    OBJECTIVE: Long-term steroid use increases the risk of developing Pneumocystis pneumonia (PcP), but there are limited reports on the relation of long-term steroid and PcP mortality. METHODS: Retrospective multicenter study to identify risk factors for PcP mortality, including average steroid dose before the first visit for PcP in non-human immunodeficiency virus (HIV)-PcP patients. We generated receiver operating characteristic (ROC) curves for 90-day all-cause mortality and the mean daily steroid dose per unit body weight in the preceding 10 to 90 days in 10-day increments. Patients were dichotomized by 90-day mortality and propensity score-based stabilized inverse probability of treatment weighting (IPTW) adjusted covariates of age, sex, and underlying disease. Multivariate analysis with logistic regression assessed whether long-term corticosteroid use affected outcome. RESULTS: Of 133 patients with non-HIV-PcP, 37 died within 90 days of initial diagnosis. The area under the ROC curve for 1-40 days was highest, and the optimal cutoff point of median adjunctive corticosteroid dosage was 0.34 mg/kg/day. Past steroid dose, underlying interstitial lung disease and emphysema, lower serum albumin and lower lymphocyte count, higher lactate dehydrogenase, use of therapeutic pentamidine and therapeutic high-dose steroids were all significantly associated with mortality. Underlying autoimmune disease, past immunosuppressant use, and a longer time from onset to start of treatment, were associated lower mortality. Logistic regression analysis after adjusting for age, sex, and underlying disease with IPTW revealed that steroid dose 1-40 days before the first visit for PcP (per 0.1 mg/kg/day increment, odds ratio 1.36 [95% confidence interval = 1.16-1.66], P<0.001), low lymphocyte counts, and high lactate dehydrogenase revel were independent mortality risk factor, while respiratory failure, early steroid, and sulfamethoxazole/trimethoprim for PcP treatment did not. CONCLUSION: A steroid dose before PcP onset was strongly associated with 90-day mortality in non-HIV-PcP patients, emphasizing the importance of appropriate prophylaxis especially in this population.

    Fibrosis of the lung can occur in idiopathic pulmonary fibrosis, collagen vascular diseases, and hypersensitivity pneumonitis, among other diseases. Transforming growth factor (TGF)-β, vascular epithelial growth factor, fibroblast growth factor, and platelet-derived growth factor contribute to the pathophysiology of fibrosis. TGF-β and other cytokines, including interleukin (IL)-1β, IL-6, and IL-23, activate type-17 immunity, which is involved in pulmonary fibrosis. The components of type-17 immunity include type-17 helper T cells, γδT cells, IL-17A-producing CD8-positive T cells, invariant NKT cells, and group 3 innate lymphoid cells. IL-17A, the main cytokine of type-17 immunity, is able to induce the epithelial-mesenchymal transition in epithelial cells via a production of TGF-β, directly stimulate fibroblasts and fibrocytes, and inhibit autophagy, which otherwise protects against pulmonary fibrosis. IL-23 induces type-17 immunity and plays an important role in the acute exacerbation of pulmonary fibrosis. Clinical studies have also linked type-17 immunity to the pathogenesis of pulmonary fibrosis. Consequently, targeting type-17 immunity may serve as a new therapeutic strategy to prevent the development or exacerbation of pulmonary fibrosis.

    BACKGROUND: Dupilumab is a fully humanized monoclonal antibody that blocks interleukin-4 and interleukin-13 signals. Several large clinical trials have demonstrated the efficacy of dupilumab in patients with severe asthma. However, few studies have examined a switch to dupilumab from other biologics. METHODS: This retrospective, multi-center observational study was conducted by the Okayama Respiratory Disease Study Group. Consecutive patients with severe asthma who were switched to dupilumab from other biologics without a treatment interval between May 2019 and September 2021 were enrolled. Patients with a treatment interval of more than twice the standard dosing interval for the previous biologic prior to dupilumab administration were excluded. RESULTS: The median patient age of the 27 patients enrolled in this study was 57 years (IQR, 45-68 years). Eosinophilic chronic rhinosinusitis (ECRS)/chronic rhinosinusitis with nasal polyp (CRSwNP) was confirmed in 23 patients. Previous biologics consisted of omalizumab (n = 3), mepolizumab (n = 3), and benralizumab (n = 21). Dupilumab significantly improved FEV1 (median improvement: +145 mL) and the asthma control test score (median improvement: +2). The overall response rate in patients receiving dupilumab for asthma as determined using the Global Evaluations of Treatment Effectiveness (GETE) was 77.8%. There were no significant differences in the baseline characteristics of the GETE-improved group vs. the non-GETE-improved group. ECRS/CRSwNP improved in 20 of the 23 patients (87.0%). Overall, 8 of the 27 patients (29.6%) developed transient hypereosinophilia (>1500/μL), but all were asymptomatic and able to continue dupilumab therapy. CONCLUSIONS: Dupilumab was highly effective for the treatment of severe asthma and ECRS/CRSwNP, even in patients switched from other biologics without a treatment interval.

    We present the case of a 59-year-old woman diagnosed with Mycobacterium shinjukuense infection using mass spectrometry of bronchioalveolar lavage fluid. We initiated treatment with clarithromycin, rifampicin, and ethambutol based on the results of drug susceptibility testing, which improved lung opacities. Most previous cases were treated with the standard regimen for Mycobacterium tuberculosis. However, our regimen may provide a therapeutic option for this rare nontuberculous Mycobacterium infection.

    Neuropeptide Y (NPY) is a neuropeptide widely expressed in not only the central nervous system but also immune cells and the respiratory epithelium. Patients with chronic obstructive pulmonary disease (COPD) reportedly exhibit decreased NPY expression in the airway epithelium, but the involvement of NPY in the pathophysiology of COPD has not been defined. We investigated the role of NPY in elastase-induced emphysema. NPY-deficient (NPY-/-) mice and wild-type (NPY+/+) mice received intratracheal instillation of porcine pancreas elastase (PPE). The numbers of inflammatory cells and the levels of cytokines and chemokines in the bronchoalveolar lavage (BAL) fluid and lung homogenates were determined along with quantitative morphometry of lung sections. Intratracheal instillation of PPE induced emphysematous changes and increased NPY levels in the lungs. Compared with NPY+/+ mice, NPY-/- mice had significantly enhanced PPE-induced emphysematous changes and alveolar enlargement. Neutrophilia seen in BAL flu12id of NPY+/+ mice on day 4 after PPE instillation was also enhanced in NPY-/- mice, and the enhancement was associated with increased levels of neutrophil-related and macrophage-related chemokines and IL-17A as well as increased numbers of type 3 innate lymphoid cells in the airways. Treatment with NPY significantly reduced PPE-induced emphysematous changes. Conversely, treatment with a NPY receptor antagonist exacerbated PPE-induced emphysematous changes. These observations indicate that NPY has protective effects against elastase-induced emphysema, and suggest that targeting NPY in emphysema has potential as a therapeutic strategy for delaying disease progression.

    BACKGROUND: Acute respiratory distress syndrome, which is caused by acute lung injury, is a destructive respiratory disorder caused by a systemic inflammatory response. Persistent inflammation results in irreversible alveolar fibrosis. Because hydrogen gas possesses anti-inflammatory properties, we hypothesized that daily repeated inhalation of hydrogen gas could suppress persistent lung inflammation by inducing functional changes in macrophages, and consequently inhibit lung fibrosis during late-phase lung injury. METHODS: To test this hypothesis, lung injury was induced in mice by intratracheal administration of bleomycin (1.0 mg/kg). Mice were exposed to control gas (air) or hydrogen (3.2% in air) for 6 h every day for 7 or 21 days. Respiratory physiology, tissue pathology, markers of inflammation, and macrophage phenotypes were examined. RESULTS: Mice with bleomycin-induced lung injury that received daily hydrogen therapy for 21 days (BH group) exhibited higher static compliance (0.056 mL/cmH2O, 95% CI 0.047-0.064) than mice with bleomycin-induced lung injury exposed only to air (BA group; 0.042 mL/cmH2O, 95% CI 0.031-0.053, p = 0.02) and lower static elastance (BH 18.8 cmH2O/mL, [95% CI 15.4-22.2] vs. BA 26.7 cmH2O/mL [95% CI 19.6-33.8], p = 0.02). When the mRNA levels of pro-inflammatory cytokines were examined 7 days after bleomycin administration, interleukin (IL)-6, IL-4 and IL-13 were significantly lower in the BH group than in the BA group. There were significantly fewer M2-biased macrophages in the alveolar interstitium of the BH group than in the BA group (3.1% [95% CI 1.6-4.5%] vs. 1.1% [95% CI 0.3-1.8%], p = 0.008). CONCLUSIONS: The results suggest that hydrogen inhalation inhibits the deterioration of respiratory physiological function and alveolar fibrosis in this model of lung injury.

    The respiratory system is continuously exposed to endogenous and exogenous oxidants. Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation of the airways, leading to the destruction of lung parenchyma (emphysema) and declining pulmonary function. It is increasingly obvious that reactive oxygen species (ROS) and reactive nitrogen species (RNS) contribute to the progression and amplification of the inflammatory responses related to this disease. First, we described the association between cigarette smoking, the most representative exogenous oxidant, and COPD and then presented the multiple pathophysiological aspects of ROS and antioxidative defense systems in the development and progression of COPD. Second, the relationship between nitric oxide system (endothelial) dysfunction and oxidative stress has been discussed. Third, we have provided data on the use of these biomarkers in the pathogenetic mechanisms involved in COPD and its progression and presented an overview of oxidative stress biomarkers having clinical applications in respiratory medicine, including those in exhaled breath, as per recent observations. Finally, we explained the findings of recent clinical and experimental studies evaluating the efficacy of antioxidative interventions for COPD. Future breakthroughs in antioxidative therapy may provide a promising therapeutic strategy for the prevention and treatment of COPD.

    Acute exacerbation of idiopathic pulmonary fibrosis has a poor prognosis associated with neutrophilic inflammation. Interleukin-23 is a proinflammatory cytokine involved in neutrophilic inflammation. However, little is known about its role in acute exacerbation of pulmonary fibrosis. This study was performed to determine the role of interleukin-23 in acute exacerbation of pulmonary fibrosis. For assessment of acute exacerbation of pulmonary fibrosis, mice were intratracheally administered bleomycin followed by lipopolysaccharide. Inflammatory cells, cytokine levels, and morphological morphometry of the lungs were analyzed. Cytokine levels were measured in the bronchoalveolar lavage fluid of idiopathic pulmonary fibrosis patients with or without acute exacerbation. Interleukin-23, -17A, and -22 levels were increased in the airway of mice with acute exacerbation of pulmonary fibrosis. Interleukin-23p19-deficient mice with acute exacerbation of pulmonary fibrosis had markedly reduced airway inflammation and fibrosis associated with decreased levels of interleukin-17A and -22 compared with wild-type mice. Treatment with an anti-interleukin-23 antibody attenuated airway inflammation and fibrosis and reduced interleukin-17A and -22 levels in mice with acute exacerbation of pulmonary fibrosis. T helper 17 cells were the predominant source of interleukin-17A in mice with acute exacerbation of pulmonary fibrosis. Interleukin-23 levels in bronchoalveolar lavage fluid tended to be higher in idiopathic pulmonary fibrosis patients with than without acute exacerbation. The data presented here suggest that interleukin-23 is essential for the development of acute exacerbation of pulmonary fibrosis, and that blockade of interleukin-23 may be a new therapeutic strategy for acute exacerbation of pulmonary fibrosis.

    A 68-year-old man presented with a solid mass at the left renal pelvis and ureter with multiple systemic lymphadenopathies and a mass with a cavity in the right lower lobe of the lung. While a transbronchial lung biopsy revealed no malignancy, a biopsy of the renal pelvis showed marginal zone lymphoma with polyclonal IgG4-positive cells. The serum IgG4 level and presence of a bilateral orbital mass suggested Mikulicz disease. The lesions shrank following the administration of steroids. A rebiopsy confirmed lung adenocarcinoma, and its background showed IgG4-positive cells a year later. IgG4-related diseases require careful follow-up because they can be complicated by malignancy.

    A 16-year-old boy with asthma participated in recovery volunteer work following the 2018 heavy rains in Japan. One month later, he experienced chest pain and dyspnea. Chest computed tomography revealed a cavity with a fungal ball, and Aspergillus fumigatus was detected in his bronchoalveolar lavage fluid. He was treated with voriconazole, but new consolidations appeared rapidly. He also experienced allergic bronchopulmonary aspergillosis. After prednisolone prescription, the consolidations improved; however, his asthma worsened. He underwent partial lung resection to avoid allergens, and his symptoms improved. We must recognize cases of infection after a disaster, especially in patients with chronic respiratory diseases.

    Cryptococcosis is an invasive mycosis that has become increasingly prevalent in immunocompromised patients. Pregnant women are also one of the risk populations for cryptococcosis. Reversal of Th2 to Th1 response following resolution of immunosuppression during the postpartum period can lead to overt clinical manifestations of a previously silent infection, resembling an immune reconstitution inflammatory syndrome. Here, we report a case of a 30-year-old woman who had an exacerbation of pulmonary cryptococcosis in the postpartum period mimicking an immune reconstitution inflammatory syndrome. In the present case, chest computed tomography showed multiple small nodules on the day of the delivery; however, pulmonary cryptococcosis, which was subclinical during pregnancy, rapidly worsened to mass-like consolidation at one month after the delivery. Pathohistological examination of the lung specimen showed lung parenchyma infiltration with histiocytes and numerous lymphocytes without granulomatous formations, and a small number of yeast-like organisms consistent with Cryptococcus without capillary involvement. Immunohistochemical staining showed predominance of CD3+ cells and CD4+ cells over CD8+ cells. In addition, GATA3+ cells dominated over T-bet + cells. These data suggested exacerbation of pulmonary cryptococcosis associated with enhancement of Th2 response in the postpartum period.

    BACKGROUND: IL-33, which is known to induce type 2 immune responses via group 2 innate lymphoid cells, has been reported to contribute to neutrophilic airway inflammation in chronic obstructive pulmonary disease. However, its role in the pathogenesis of emphysema remains unclear. METHODS: We determined the role of interleukin (IL)-33 in the development of emphysema using porcine pancreas elastase (PPE) and cigarette smoke extract (CSE) in mice. First, IL-33-/- mice and wild-type (WT) mice were given PPE intratracheally. The numbers of inflammatory cells, and the levels of cytokines and chemokines in the bronchoalveolar lavage (BAL) fluid and lung homogenates, were analyzed; quantitative morphometry of lung sections was also performed. Second, mice received CSE by intratracheal instillation. Quantitative morphometry of lung sections was then performed again. RESULTS: Intratracheal instillation of PPE induced emphysematous changes and increased IL-33 levels in the lungs. Compared to WT mice, IL-33-/- mice showed significantly greater PPE-induced emphysematous changes. No differences were observed between IL-33-/- and WT mice in the numbers of macrophages or neutrophils in BAL fluid. The levels of hepatocyte growth factor were lower in the BAL fluid of PPE-treated IL-33-/- mice than WT mice. IL-33-/- mice also showed significantly greater emphysematous changes in the lungs, compared to WT mice, following intratracheal instillation of CSE. CONCLUSION: These observations suggest that loss of IL-33 promotes the development of emphysema and may be potentially harmful to patients with COPD.

    Hermansky-Pudlak syndrome (HPS) is an autosomal recessive hereditary disease that may be complicated by progressive and potentially fatal interstitial pneumonia. We herein report a 64-year-old woman with interstitial pneumonia associated with HPS type 4 whom we treated with nintedanib after pirfenidone proved ineffective. To our knowledge, there have been no previous reports of nintedanib being used to treat a patient with HPS type 4. There is a need for clinical trials of antifibrotic agents, including nintedanib, pirfenidone, and new therapeutic agents with different mechanisms of action in these patients.

    In patients with interstitial pneumonia, pulmonary fibrosis is an irreversible condition that can cause respiratory failure. Novel treatments for pulmonary fibrosis are necessary. Inflammation is thought to activate lung fibroblasts, resulting in pulmonary fibrosis. Of the known inflammatory molecules, we have focused on S100A8/A9 from the onset of inflammation to the subsequent progression of inflammation. Our findings confirmed the high expression of S100A8/A9 in specimens from patients with pulmonary fibrosis. An active role of S100A8/A9 was demonstrated not only in the proliferation of fibroblasts but also in the fibroblasts' differentiation to myofibroblasts (the active form of fibroblasts). S100A8/A9 also forced fibroblasts to upregulate the production of collagen. These effects were induced via the receptor of S100A8/A9, i.e., the receptor for advanced glycation end products (RAGE), on fibroblasts. The anti-S100A8/A9 neutralizing antibody inhibited the effects of S100A8/A9 on fibroblasts and suppressed the progression of fibrosis in bleomycin (BLM)-induced pulmonary fibrosis mouse model. Our findings strongly suggest a crucial role of S100A8/A9 in pulmonary fibrosis and the usefulness of S100A8/A9-targeting therapy for fibrosis interstitial pneumonia. HIGHLIGHTS: S100A8/A9 level is highly upregulated in the IPF patients' lungs as well as the blood. S100A8/A9 promotes not only the growth of fibroblasts but also differentiation to myofibroblasts. The cell surface RAGE acts as a crucial receptor to the extracellular S100A8/A9 in fibroblasts. The anti-S100A8/A9 antibody effectively suppresses the progression of IPF in a mouse model. In idiopathic pulmonary fibrosis (IPF), S100A8/A9, a heterodimer composed of S100A8 and S100A9 proteins, plays a crucial role in the onset of inflammation and the subsequent formation of a feed-forward inflammatory loop that promotes fibrosis. (1) The local, pronounced increase in S100A8/A9 in the injured inflammatory lung region-which is provided mainly by the activated neutrophils and macrophages-exerts strong inflammatory signals accompanied by dozens of inflammatory soluble factors including cytokines, chemokines, and growth factors that further act to produce and secrete S100A8/A9, eventually making a sustainable inflammatory circuit that supplies an indefinite presence of S100A8/A9 in the extracellular space with a mal-increased level. (2) The elevated S100A8/A9 compels fibroblasts to activate through receptor for advanced glycation end products (RAGE), one of the major S100A8/A9 receptors, resulting in the activation of NFκB, leading to fibroblast mal-events (e.g., elevated cell proliferation and transdifferentiation to myofibroblasts) that actively produce not only inflammatory cytokines but also collagen matrices. (3) Finally, the S100A8/A9-derived activation of lung fibroblasts under a chronic inflammation state leads to fibrosis events and constantly worsens fibrosis in the lung. Taken together, these findings suggest that the extracellular S100A8/A9 heterodimer protein is a novel mainstay soluble factor for IPF that exerts many functions as described above (1-3). Against this background, we herein applied the developed S100A8/A9 neutralizing antibody to prevent IPF. The IPF imitating lung fibrosis in an IPF mouse model was effectively blocked by treatment with the antibody, leading to enhanced survival. The developed S100A8/A9 antibody, as an innovative novel biologic, may help shed light on the difficulties encountered with IPF therapy in clinical settings.

    BACKGROUND: Pirfenidone suppresses the decline of forced vital capacity (FVC) in patients with idiopathic pulmonary fibrosis (IPF). However, IPF progresses in some patients despite treatment. We analyzed patients with meaningful FVC declines during pirfenidone treatment and explored the factors predictive of disease progression after FVC decline. METHODS: This study was a retrospective, multicenter, observational study conducted by the Okayama Respiratory Disease Study Group. We defined initial decline in %FVC as 5% or greater per 6-month period during pirfenidone treatment. IPF patients who were treated with pirfenidone and experienced an initial decline from December 2008 to September 2017 were enrolled. RESULTS: We analyzed 21 patients with IPF. After the initial decline, 4 (19.0%) patients showed improvement in disease, 11 (52.4%) showed stable disease, and 6 (28.6%) showed progressive disease. There was no significant correlation between %FVC reduction on initial decline and subsequent %FVC change (p = 0.475). Deterioration of high-resolution computed tomography (HRCT) findings on initial decline was observed significantly more often in the progressive versus improved/stable disease groups (100% vs 20.0%, p = 0.009). CONCLUSIONS: We revealed that deterioration of HRCT findings may predict disease progression after the initial decline in %FVC in IPF patients treated with pirfenidone.

    BACKGROUND: Nintedanib is a multi-kinase inhibitor approved for idiopathic pulmonary fibrosis (IPF); however, its efficacy and safety for patients with IPF and restricted pulmonary function remain unclear. Therefore, the objective of this study was to determine the efficacy and safety of nintedanib for patients with IPF and forced vital capacity (FVC) ≤ 50%. METHODS: This was a multi-center retrospective study performed by the Okayama Respiratory Disease Study Group. Patients were allocated into FVC ≤ 50% and FVC > 50% groups based on their predicted FVC. The primary endpoints were FVC changes from baseline after 6 and 12 months. RESULTS: 45 patients were eligible for the study. 18 patients had FVC ≤ 50%, and 27 patients had FVC > 50%. Overall, 31 and 19 patients underwent pulmonary function tests at 6 and 12 months after initiating nintedanib, respectively. FVC changes from baseline at 6 and 12 months after initiating nintedanib were comparable between the two groups. Adverse events were seen in all patients, and the rates of patients who discontinued nintedanib were also comparable (38.9% vs. 37.0%, p = 1.000). Multiple regression analysis showed that age and forced expiratory volume in 1 second (FEV1)/FVC were negatively correlated with changes in FVC at 6 months after initiating nintedanib. CONCLUSIONS: Our data suggest that nintedanib can be a useful agent for IPF patients, including those with a low FVC, and that age and FEV1/FVC are predictive markers for changes in FVC following nintedanib treatment.

    Neuropeptide Y (NPY) is a neurotransmitter that is widely expressed in the brain and peripheral nervous system. Various immune cells express the receptor for NPY, Y1 receptor. NPY modulates these cells via its Y1 receptor, and involvement of NPY in the pathophysiology of bronchial asthma, has been reported. Increased plasma levels of NPY in asthmatic patients have been reported. NPY polymorphisms are associated with an increased risk for asthma in overweight subjects and young adults. We and other researchers have reported that using murine models of allergic airway responses, NPY and Y1 receptor play critical roles for the development of allergic airway inflammation and airway hyperresponsiveness. Therefore, manipulating NPY-Y1 pathway represents a novel therapeutic target to control allergic airway responses, and might be beneficial for treatment of bronchial asthma.

    BACKGROUND: Retinoid X receptors (RXRs) are members of the nuclear receptor (NR) superfamily that mediate signalling by 9-cis retinoic acid, a vitamin A derivative. RXRs play key roles not only as homodimers but also as heterodimeric partners, e.g., for retinoic acid receptors, vitamin D receptors, and peroxisome proliferator-activated receptors. The NR family may also play important roles in the development of emphysema. However, the role of RXRs in the pathogenesis of emphysema is not well defined. METHODS: We developed a novel RXR partial agonist (NEt-4IB) and investigated its effect and mechanism compared to a full agonist (bexarotene) in a murine model of emphysema. For emphysema induction, BALB/c mice received intraperitoneal cigarette smoke extract (CSE) or intratracheal porcine pancreas elastase (PPE). Treatment with RXR agonists was initiated before or after emphysema induction. RESULTS: Treatment with NEt-4IB significantly suppressed the increase in static lung compliance and emphysematous changes in CSE-induced emphysema and PPE-induced established and progressive emphysema. NEt-4IB significantly suppressed PPE-induced neutrophilic airway inflammation and the levels of keratinocyte chemoattractant (KC), C-X-C motif ligand5 (CXCL5), interferon (IFN)-γ and IL-17. NEt-4IB also improved the matrix metalloproteinase-9 (MMP-9)/tissue inhibitor of metalloproteinase-1 (TIMP-1) imbalance and the reduced anti-oxidant activity in bronchoalveolar lavage (BAL) fluid. NEt-4IB suppressed PPE-induced vascular endothelial growth factor (VEGF) expression in the airway. Treatment with NEt-4IB and bexarotene significantly suppressed the increase in static lung compliance and emphysematous changes. However, adverse effects of RXR agonists, including hypertriglyceridemia and hepatomegaly, were observed in bexarotene-treated mice but not in NEt-4IB-treated mice. CONCLUSION: These data suggest that RXRs play crucial roles in emphysema and airway inflammation, and novel partial RXR agonists could be potential therapeutic strategies for the treatment of PPE- and CSE-induced emphysema.

    Although recent retrospective studies suggested that the use of beta-blockers appears to help improve the mortality rate and decrease the rate of exacerbation in chronic obstructive pulmonary disease (COPD) patients with heart failure, the effects of beta-blockers on COPD patients without heart failure have not been established. Based on previous reports, we have launched a multicenter, prospective, single-arm phase II study to evaluate the preventive effect of the cardioselective beta-blocker bisoprolol in COPD exacerbation, in Japanese individuals with moderate-to-severe COPD who do not have heart failure but do have hypertension requiring the use of medication. The primary endpoint is the rate of mild-to-severe COPD exacerbation. The results of this study will clarify whether bisoprolol can prevent exacerbation in COPD patients without heart failure.

    BACKGROUND: Lung transplants have produced very favorable outcomes for patients with interstitial lung disease (ILD) in Japan. However, because of the severe donor lung shortage, patients must wait approximately 2.5 years before they can undergo transplantation and many candidates die before allocation. We reveal the clinical characteristics of Japanese patients with ILD who are candidates for lung transplants and the risk factors for early death while on the waiting list. METHODS: We retrospectively reviewed the clinical data of patients registered in the Japan Organ Transplant Network from Okayama University Hospital who are candidates for cadaveric lung transplants for ILD between 1999 and 2015. RESULTS: Fifty-three patients with ILD were included (24 patients with idiopathic pulmonary fibrosis and 29 others). They had severe pulmonary dysfunction and low exercise tolerability. The median waiting time for transplantation was 462 days, and 22 patients died before allocation. Patients who died before 462 days without undergoing transplantation had more severe dyspnea, shorter 6-minute walk distance (6MWD), and lower performance status than those who waited ≥462 days. CONCLUSIONS: Japanese candidates for cadaveric lung transplants for ILD have severe pulmonary dysfunction. Severe dyspnea, short 6MWD, and low performance status are risk factors for early death while on the waiting list.

    Background: Some recent studies have suggested that beta-blocker use in patients with chronic obstructive pulmonary disease (COPD) is associated with a reduction in the frequency of acute exacerbations. However, the long-term effects of beta-blocker use on lung function of COPD patients have hardly been evaluated. Patients and methods: We retrospectively reviewed 31 Japanese COPD patients taking beta-blockers for &gt
    1 year and 72 patients not taking them. The association between beta-blocker use and the annual change in forced expiratory volume in 1 second (FEV1) was assessed. Results: At baseline, patient demographic characteristics were as follows: 97 males (mean age 67.0±8.2 years)
    32 current smokers
    and Global Initiative for Chronic Obstructive Lung disease (GOLD) stages I: n=26, II: n=52, III: n=19, and IV: n=6. Patients taking beta-blockers exhibited a significantly lower forced vital capacity (FVC), FEV1, and %FVC, and a more advanced GOLD stage. The mean duration of beta-blocker administration was 2.8±1.7 years. There were no differences in the annual change in FEV1 between patients who did and did not use beta-blockers (-7.6±93.5 mL/year vs -4.7±118.9 mL/year, P=0.671). After controlling for relevant confounders in multivariate analyses, it was found that beta-blocker use was not significantly associated with the annual decline in FEV1 (β=-0.019
    95% confidence interval: -0.073 to 0.036
    P=0.503). Conclusion: Long-term beta-blocker use in Japanese COPD patients might not affect the FEV1, one of the most important parameters of lung function in COPD patients.

    Background: Retinoid X receptors (RXRs) are members of the nuclear receptor (NR) superfamily that mediate signaling by 9-cis retinoic acid, a vitamin A (retinol) derivative. RXRs play key roles not only as homodimers but also as heterodimeric partners-e.g., retinoic acid receptors (RARs), vitamin D receptors (VDRs), liver X receptors (LXRs), and peroxisome proliferator-activated receptors (PPARs). The NR family was recently associated with allergic diseases, but the role of RXRs in allergen-induced airway responses is not well defined. The goal of this study is to elucidate the role of RXRs in asthma pathogenesis and the potency of RXR partial agonist in the treatment of allergic airway inflammation and airway hyperresponsiveness using a murine model of asthma. Methods: We investigated the effect of a novel RXR partial agonist (NEt-4IB) on the development of allergic airway inflammation and airway hyperresponsiveness (AHR) in a murine model of asthma. Balb/c mice were sensitized (days 0 and 14) and challenged (days 28-30) with ovalbumin (OVA), and airway inflammation and airway responses were monitored 48 h after the last OVA challenge. NEt-4IB was administered orally on days 25 to 32. Results: Oral administration of NEt-4IB significantly suppressed AHR and inflammatory cell accumulation in the airways and attenuated the levels of TNF-α in the lung and IL-5, IL-13 and NO levels in bronchoalveolar lavage (BAL) fluid and the number of periodic acid Schiff (PAS)-positive goblet cells in lung tissue. Treatment with NEt-4IB also significantly suppressed NF-ΚB expression. Conclusion: These data suggest that RXRs may be of crucial importance in the mechanism of allergic asthma and that the novel RXR partial agonist NEt-4IB may be a promising candidate for the treatment of allergic airway inflammation and airway hyperresponsiveness in a model of allergic asthma.

    Background: Retinoid X receptors (RXRs) are members of the nuclear receptor (NR) superfamily that mediate signaling by 9-cis retinoic acid, a vitamin A (retinol) derivative. RXRs play key roles not only as homodimers but also as heterodimeric partners-e.g., retinoic acid receptors (RARs), vitamin D receptors (VDRs), liver X receptors (LXRs), and peroxisome proliferator-activated receptors (PPARs). The NR family was recently associated with allergic diseases, but the role of RXRs in allergen-induced airway responses is not well defined. The goal of this study is to elucidate the role of RXRs in asthma pathogenesis and the potency of RXR partial agonist in the treatment of allergic airway inflammation and airway hyperresponsiveness using a murine model of asthma.

    We herein report the case of a 44-year-old man who was diagnosed with pneumocystis pneumonia (PCP) concomitant with ectopic adrenocorticotropic hormone (ACTH) syndrome, which had been caused by a large cell neuroendocrine carcinoma of the thymus. Chest computed tomography revealed ground-glass opacities in the lungs. PCP was diagnosed by a polymerase chain reaction with bronchoalveolar lavage. The levels of cortisol were slowly corrected with an adrenal enzyme inhibitor, and the exacerbation of PCP was successfully avoided. Our case indicates that in addition to prophylaxis, the early diagnosis of PCP and the slow correction of hypercortisolemia should be considered in order to prevent an exacerbation due to the reconstitution of the immune function in patients with ectopic ACTH syndrome.

    Background: Some recent studies have suggested that beta-blocker use in patients with chronic obstructive pulmonary disease (COPD) is associated with a reduction in the frequency of acute exacerbations. However, the long-term effects of beta-blocker use on lung function of COPD patients have hardly been evaluated.
    Patients and methods: We retrospectively reviewed 31 Japanese COPD patients taking beta-blockers for &gt;1 year and 72 patients not taking them. The association between beta-blocker use and the annual change in forced expiratory volume in 1 second (FEV1) was assessed.
    Results: At baseline, patient demographic characteristics were as follows: 97 males (mean age 67.0 +/- 8.2 years); 32 current smokers; and Global Initiative for Chronic Obstructive Lung disease (GOLD) stages I: n=26, II: n=52, III: n=19, and IV: n=6. Patients taking beta-blockers exhibited a significantly lower forced vital capacity (FVC), FEV1, and %FVC, and a more advanced GOLD stage. The mean duration of beta-blocker administration was 2.8 +/- 1.7 years. There were no differences in the annual change in FEV1 between patients who did and did not use beta-blockers (-7.6 +/- 93.5 mL/year vs -4.7 +/- 118.9 mL/year, P=0.671). After controlling for relevant confounders in multivariate analyses, it was found that beta-blocker use was not significantly associated with the annual decline in FEV1 (beta=-0.019; 95% confidence interval: -0.073 to 0.036; P=0.503).
    Conclusion: Long-term beta-blocker use in Japanese COPD patients might not affect the FEV1, one of the most important parameters of lung function in COPD patients.

    We recently reported that IL-17A plays a critical role in the development of porcine pancreatic elastase (PPE)-induced emphysema. The proliferation of T-helper type 17 (Th17) cells was induced by IL-23. To determine the contribution of IL-23 to the development of pulmonary emphysema, a mouse model of PPE-induced emphysema was used in which responses of IL-23p19-deficient (IL-23(-/-)) and wild-type (WT) mice were compared. Intratracheal instillation of PPE induced emphysematous changes in the lungs and was associated with increased levels of IL-23 in lung homogenates. Compared with WT mice, IL-23(-/-) mice developed significantly lower static compliance values and markedly reduced emphysematous changes on histological analyses after PPE instillation. These changes were associated with lower levels of IL-17A and fewer Th17 cells in the lung. The neutrophilia seen in bronchoalveolar lavage fluid ofWTmice was attenuated in IL-23(-/-) mice, and the reduction was associated with decreased levels of keratinocyte-derived cytokine and macrophage inflammatory protein-2 in bronchoalveolar lavage fluid. Treatment with anti-IL-23p40 monoclonal antibody significantly attenuated PPE-induced emphysematous changes in the lungs of WT mice. These data identify the important contributions of IL-23 to the development of elastase-induced pulmonary inflammation and emphysema, mediated through an IL-23/IL-17 pathway. Targeting IL-23 in emphysema is a potential therapeutic strategy for delaying disease progression.

    KL-6 is a glycoprotein found predominantly on type II pneumocytes and alveolar macrophages, and often shows increased serum levels in patients with interstitial pneumonia. We report a case of mycobacterium avium complex (MAC) infection whose disease activity was correlated with KL-6 levels in serum. During treatment of rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) with prednisolone, chest image findings improved in association with decreased KL-6 levels. Following tapering of prednisolone, chest image findings deteriorated again as levels of KL-6 increased, suggesting recurrence of RA-ILD. Bronchoscopic examination revealed active MAC infection. Treatment of MAC infection not only improved chest image findings but also decreased KL-6 levels in serum, suggesting that KL-6 was increased by active MAC infection by itself, not by recurrence of RA-ILD. To the best of our knowledge, this is the first documentation of KL-6 elevation in serum in association with active MAC infection.

    Ambroxol is used in COPD and asthma to increase mucociliary clearance and regulate surfactant levels, perhaps through anti-oxidant and anti-inflammatory activities. To determine the role and effect of ambroxol in an experimental model of asthma, BALB/c mice were sensitized to ovalbumin (OVA) followed by 3 days of challenge. Airway hyperresponsiveness (AHR), lung cell composition and histology, and cytokine and protein carbonyl levels in bronchoalveolar lavage (BAL) fluid were determined. Ambroxol was administered either before the first OVA challenge or was begun after the last allergen challenge. Cytokine production levels from lung mononuclear cells (Lung MNCs) or alveolar macrophages (AM) were also determined. Administration of ambroxol prior to challenge suppressed AHR, airway eosinophilia, goblet cell metaplasia, and reduced inflammation in subepithelial regions. When given after challenge, AHR was suppressed but without effects on eosinophil numbers. Levels of IL-5 and IL-13 in BAL fluid were decreased when the drug was given prior to challenge; when given after challenge, increased levels of IL-10 and IL-12 were detected. Decreased levels of protein carbonyls were detected in BAL fluid following ambroxol treatment after challenge. In vitro, ambroxol increased levels of IL-10, IFN-gamma, and IL-12 from Lung MNCs and AM, whereas IL-4, IL-5, and IL-13 production was not altered. Taken together, ambroxol was effective in preventing AHR and airway inflammation through upregulation of Th1 cytokines and protection from oxidative stress in the airways.

    Acquired hemophilia A is a rare disease in which autoantibodies to factor VIII are present. It is often manifested as a sudden onset of a critical bleeding episode, and its incidence is reported to be 1.48 cases per million persons per year. We report herein on a case of acquired hemophilia A associated with a submucosal hematoma of the oral floor, pharynx, and larynx. A 78-year-old male presented with fresh bleeding from his mouth, associated with hematoma of the oral floor, pharynx, and larynx. Laboratory test showed that the activated partial thromboplastin time was prolonged, and the platelet count and prothrombin time were normal. Coagulation tests revealed decreased factor VIII levels, and the presence of factor VIII inhibitor. A diagnosis of acquired hemophilia A was made, and immunotherapy with corticosteroids was initiated. After treatment, the bleeding tendency was controlled. On hospital day 29, the symptoms disappeared. Although acquired hemophilia A is a rare coagulopathic condition, it should be considered as one of the differential diagnoses in a case of sudden onset of severe hemorrhagic tendency of unknown origin.

    The receptor for advanced glycation end-products (RAGE) is a multiligand receptor that belongs to the immunoglobulin superfamily. RAGE is reported to be involved in various inflammatory disorders; however, studies that address the role of RAGE in allergic airway disease are inconclusive. RAGE-sufficient (RAGE(+/+)) and RAGE-deficient (RAGE(-/-)) mice were sensitized to ovalbumin, and airway responses were monitored after ovalbumin challenge. RAGE(-/-) mice showed reduced eosinophilic inflammation and goblet cell metaplasia, lower T helper type 2 (Th2) cytokine production from spleen and peribronchial lymph node mononuclear cells, and lower numbers of group 2 innate lymphoid cells in the lung compared with RAGE(+/+) mice following sensitization and challenge. Experiments using irradiated, chimeric mice showed that the mice expressing RAGE on radio-resistant structural cells but not hematopoietic cells developed allergic airway inflammation; however, the mice expressing RAGE on hematopoietic cells but not structural cells showed reduced airway inflammation. In contrast, absence of RAGE expression on structural cells enhanced innate airway hyperresponsiveness (AHR). In the absence of RAGE, increased interleukin (IL)-33 levels in the lung were detected, and blockade of IL-33 receptor ST2 suppressed innate AHR in RAGE(-/-) mice. These data identify the importance of RAGE expressed on lung structural cells in the development of allergic airway inflammation, T helper type 2 cell activation, and group 2 innate lymphoid cell accumulation in the airways. RAGE on lung structural cells also regulated innate AHR, likely through the IL-33-ST2 pathway. Thus manipulating RAGE represents a novel therapeutic target in controlling allergic airway responses.

    Pulmonary emphysema is characterized by persistent inflammation and progressive alveolar destruction. The receptor for advanced glycation end-products (RAGE) is a multiligand cell surface receptor reported to be involved in the process of acute alveolar epithelial cell injury. However, studies that address the role of RAGE in pulmonary emphysema are inconclusive. We investigated the role of RAGE in the development of elastase-induced pulmonary inflammation and emphysema in mice. RAGE-sufficient (RAGE(+/+)) mice and RAGE-deficient (RAGE(-/-)) mice were treated with intratracheal elastase on Day 0. Airway inflammation, static lung compliance, lung histology, and the levels of neutrophil-related chemokine and proinflammatory cytokines in bronchoalveolar lavage fluid were determined on Days 4 and 21. Neutrophilia in bronchoalveolar lavage fluid, seen in elastase-treated RAGE(+/+) mice, was reduced in elastase-treated RAGE(-/-) mice on Day 4, and was associated with decreased levels of keratinocyte chemoattractant, macrophage inflammatory protein-2, and IL-1 beta. Static lung compliance values and emphysematous changes in the lung tissue were decreased in RAGE(-/-) mice compared with RAGE(+/+) mice on Day 21 after elastase treatment. Experiments using irradiated, bone marrow-chimeric mice showed that the mice expressing RAGE on radioresistant structural cells, but not hematopoietic cells, developed elastase-induced neutrophilia and emphysematous change in the lung. In contrast, mice expressing RAGE on hematopoietic cells, but not radioresistant structural cells, showed reduced neutrophilia and emphysematous change in the lung. These data identify the importance of RAGE expressed on lung structural cells in the development of elastase-induced pulmonary inflammation and emphysema. Thus, RAGE represents a novel therapeutic target for preventing pulmonary emphysema.

    The incidence of overlapping bronchial asthma and chronic obstructive pulmonary disease has increased in recent years. Cysteinyl leukotrienes (CysLTs) play an important role in asthma, and the type 1 CysLT receptor (CysLT(1)R) is expressed by many inflammatory cells. We evaluated the effect of montelukast, a CysLT(1)R antagonist, on mouse models of asthma, porcine pancreatic elastase (PPE)-induced emphysema, and asthma combined with emphysema. Mice were sensitized with ovalbumin (OVA) on Days 0 and 14 and subsequently challenged with OVA on Days 28, 29, and 30. Pulmonary emphysema was induced by intratracheal instillation of PPE on Day 25. Mice were treated subcutaneously with montelukast or vehicle from Day 25 to Day 31. Airway hyperresponsiveness (AHR), static compliance; the number of inflammatory cells, the levels of cytokines, chemokines, LTs, and perforin in the bronchoalveolar lavage fluid, and the quantitative morphometry of lung sections were analyzed on Day 32. Treatment with montelukast significantly attenuated the AHR and eosinophilic airway inflammation in OVA-sensitized and OVA-challenged mice. Administration of montelukast significantly reduced the AHR, static compliance, and neutrophilic airway inflammation, while attenuating emphysematous lung changes, in PPE-treated mice. In PPE-treated mice subjected to allergen sensitization and challenges, montelukast significantly suppressed the AHR, static compliance, and eosinophilic and neutrophilic airway inflammation in addition to the development of experimentally induced emphysema in the lungs. Our data suggest that CysLT(1)R antagonists may be effective in ameliorating the consequences of PPE-induced lung damage and the changes that follow allergen sensitization and challenges.

    We herein report the case of a 68-year-old man diagnosed with invasive mucinous adenocarcinoma of the lungs. Chest computed tomography showed subpleural ground-glass opacity and small nodules with cavitation. A culture of the bronchoalveolar lavage fluid resulted in the detection of Mycobacterium fortuitum. The patient's lung consolidation rapidly progressed; however, repeated bronchoscopy showed no atypical cells, thus suggesting a diagnosis of organizing pneumonia associated with M. fortuitum infection. However, the surgical biopsy specimen was diagnostic for adenocarcinoma, with no mycobacterial infection. Invasive mucinous adenocarcinoma should not be excluded in the differential diagnosis of patients with clinical features of organizing pneumonia and nontuberculous mycobacterium infection, even if a transbronchial biopsy confirms the absence of malignancy.

    Background: Chronic asthma is often associated with neutrophilic infiltration in the airways. Neutrophils contain elastase, a potent secretagogue in the airways, nonetheless the role for neutrophil elastase as well as neutrophilic inflammation in allergen-induced airway responses is not well defined. In this study, we have investigated the impact of neutrophil elastase inhibition on the development of allergic airway inflammation and airway hyperresponsiveness (AHR) in previously sensitized and challenged mice.Methods: BALB/c mice were sensitized and challenged (primary) with ovalbumin (OVA). Six weeks later, a single OVA aerosol (secondary challenge) was delivered and airway inflammation and airway responses were monitored 6 and 48 hrs later. An inhibitor of neutrophil elastase was administered prior to secondary challenge.Results: Mice developed a two-phase airway inflammatory response after secondary allergen challenge, one neutrophilic at 6 hr and the other eosinophilic, at 48 hr. PAR-2 expression in the lung tissues was enhanced following secondary challenge, and that PAR-2 intracellular expression on peribronchial lymph node (PBLN) T cells was also increased following allergen challenge of sensitized mice. Inhibition of neutrophil elastase significantly attenuated AHR, goblet cell metaplasia, and inflammatory cell accumulation in the airways following secondary OVA challenge. Levels of IL-4, IL-5 and IL-13, and eotaxin in BAL fluid 6 hr after secondary allergen challenge were significantly suppressed by the treatment. At 48 hr, treatment with the neutrophil elastase inhibitor significantly reduced the levels of IL-13 and TGF-β1 in the BAL fluid. In parallel, in vitro IL-13 production was significantly inhibited in spleen cells from sensitized mice.Conclusion: These data indicate that neutrophil elastase plays an important role in the development of allergic airway inflammation and hyperresponsiveness, and would suggest that the neutrophil elastase inhibitor reduced AHR to inhaled methacholine indicating the potential for its use as a modulator of the immune/inflammatory response in both the neutrophil- and eosinophil-dominant phases of the response to secondary allergen challenge. © 2013 Koga et al.

    Background: Pulmonary emphysema is characterized by alveolar destruction and persistent inflammation of the airways. Although IL-17A contributes to many chronic inflammatory diseases, it's role in the inflammatory response of elastase-induced emphysema remains unclear.Methods: In a model of elastase-induced pulmonary emphysema we examined the response of IL-17A-deficient mice, monitoring airway inflammation, static compliance, lung histology and levels of neutrophil-related chemokine and pro-inflammatory cytokines in bronchoalveolar lavage (BAL) fluid.Results: Wild-type mice developed emphysematous changes in the lung tissue on day 21 after elastase treatment, whereas emphysematous changes were decreased in IL-17A-deficient mice compared to wild-type mice. Neutrophilia in BAL fluid, seen in elastase-treated wild-type mice, was reduced in elastase-treated IL-17A-deficient mice on day 4, associated with decreased levels of KC, MIP-2 and IL-1 beta. Elastase-treated wild-type mice showed increased IL-17A levels as well as increased numbers of IL-17A+ CD4 T cells in the lung in the initial period following elastase treatment.Conclusions: These data identify the important contribution of IL-17A in the development of elastase-induced pulmonary inflammation and emphysema. Targeting IL-17A in emphysema may be a potential therapeutic strategy for delaying disease progression. © 2013 Kurimoto et al.

    Background: Chronic asthma is often associated with neutrophilic infiltration in the airways. Neutrophils contain elastase, a potent secretagogue in the airways, nonetheless the role for neutrophil elastase as well as neutrophilic inflammation in allergen-induced airway responses is not well defined. In this study, we have investigated the impact of neutrophil elastase inhibition on the development of allergic airway inflammation and airway hyperresponsiveness (AHR) in previously sensitized and challenged mice.
    Methods: BALB/c mice were sensitized and challenged (primary) with ovalbumin (OVA). Six weeks later, a single OVA aerosol (secondary challenge) was delivered and airway inflammation and airway responses were monitored 6 and 48 hrs later. An inhibitor of neutrophil elastase was administered prior to secondary challenge.
    Results: Mice developed a two-phase airway inflammatory response after secondary allergen challenge, one neutrophilic at 6 hr and the other eosinophilic, at 48 hr. PAR-2 expression in the lung tissues was enhanced following secondary challenge, and that PAR-2 intracellular expression on peribronchial lymph node (PBLN) T cells was also increased following allergen challenge of sensitized mice. Inhibition of neutrophil elastase significantly attenuated AHR, goblet cell metaplasia, and inflammatory cell accumulation in the airways following secondary OVA challenge. Levels of IL-4, IL-5 and IL-13, and eotaxin in BAL fluid 6 hr after secondary allergen challenge were significantly suppressed by the treatment. At 48 hr, treatment with the neutrophil elastase inhibitor significantly reduced the levels of IL-13 and TGF-beta 1 in the BAL fluid. In parallel, in vitro IL-13 production was significantly inhibited in spleen cells from sensitized mice.
    Conclusion: These data indicate that neutrophil elastase plays an important role in the development of allergic airway inflammation and hyperresponsiveness, and would suggest that the neutrophil elastase inhibitor reduced AHR to inhaled methacholine indicating the potential for its use as a modulator of the immune/inflammatory response in both the neutrophil-and eosinophil-dominant phases of the response to secondary allergen challenge.

    A 32-year-old male with CATCH22 syndrome presented with a high fever and productive cough after taking drugs for acute bronchitis, including L-carbocisteine. Chest radiography revealed ground-glass opacities in the bilateral lung fields. He had a history of similar pneumonia. Under the assumption of drug-induced pneumonia, or bacterial or viral pneumonia, all drugs including L-carbocisteine were discontinued, and antibiotics were started. A drug-induced lymphocyte stimulation test was positive only for L-carbocisteine. The only drug in common between this and the previous episode of pneumonia was L-carbocisteine. We thus concluded that this was a definite case of L-carbocisteine-induced pneumonia in a patient with CATCH22 syndrome.

    Bronchiolitis obliterans (BO) is a disease with a poor prognosis, and a key factor that limits long-term survival after allogeneic hematopoietic stem cell transplantation (HSCT). We here report a case of a 31-year woman with acute lymphatic leukemia, which was treated by chemotherapy and HSCT, and consequently developed BO 2 years after HSCT. A non-tuberculous mycobacterial infection occurred and showed gradual exacerbation. She started taking anti-mycobacterial drugs, but lost appetite, felt tired and finally lost consciousness one month after beginning medication. Arterial blood gas revealed marked hypercapnia. Using extracorporeal life support (ECLS), the carbon dioxide concentration was reduced and her consciousness recovered. To our knowledge, this is the first case in which ECLS was successfully used for hypercapnia in a patient with BO.

    Chemokine receptor (CCR) 5 is expressed on dendritic cells, macrophages, CD8 cells, memory CD4 T cells, and stromal cells, and is frequently used as a marker of T helper type 1 cells. Interventions that abrogate CCR5 or interfere with its ligand binding have been shown to alter T helper type 2-induced inflammatory responses. The role of CCR5 on allergic airway responses is not defined. CCR5-deficient (CCR5(-/-)) and wild-type (CCR5(+/+)) mice were sensitized and challenged with ovalbumin (OVA) and allergic airway responses were monitored 48 hours after the last OVA challenge. Cytokine levels in lung cell culture supernatants were also assessed. CCR5(-/-) mice showed significantly lower airway hyperresponsiveness (AHR) and lower numbers of total cells, eosinophils, and lymphocytes in bronchoalveolar lavage (BAL) fluid compared with CCR5(+/+) mice after sensitization and challenge. The levels of IL-4 and IL-13 in BAL fluid of CCR5(-/-) mice were lower than in CCR5(+/+) mice. Decreased numbers of lung T cells were also detected in CCR5(-/-) mice after sensitization and challenge. Transfer of OVA-sensitized T cells from CCR5(+/+), but not transfer of CCR5(-/-) cells, into CCR5(-/-) mice restored AHR and numbers of eosinophils in BAL fluid after OVA challenge. Accordingly, the numbers of airway-infiltrating donor T cells were significantly higher in the recipients of CCR5(+/+) T cells. Taken together, these data suggest that CCR5 plays a pivotal role in allergen-induced AHR and airway inflammation, and that CCR5 expression on T cells is essential to the accumulation of these cells in the airways.

    Most of the studies investigating the effectiveness of blocking the leukotriene B4 (LTB4) receptor 1 (BLT1) have been performed in models of primary or acute allergen challenge. The role of the LTB4-BLT1 pathway in secondary challenge models, where airway hyperresponsiveness (AHR) and airway inflammation have been established, has not been defined. We investigated the effects of blocking BLT1 on early-and late-phase development of AHR and airway inflammation in previously sensitized and challenged mice. Female BALB/c mice were sensitized (Days 1 and 14) and challenged (primary, Days 28-30) with ovalbumin. On Day 72, mice were challenged (secondary) with a single OVA aerosol, and the early and late phases of AHR and inflammation were determined. Specific blockade of BLT1 was attained by oral administration of a BLT1 antagonist on Days 70 through 72. Administration of the antagonist inhibited the secondary ovalbumin challenge-induced alterations in airway responses during the late phase but not during the early phase, as demonstrated by decreases in AHR and in bronchoalveolar lavage neutrophilia and eosinophilia 6 and 48 hours after secondary challenge. The latter was associated with decreased levels of KC protein, macrophage inflammatory protein 2, and IL-17 in the airways. These data identify the importance of the LTB4-BLT1 pathway in the development of late-phase, allergen-induced airway responsiveness after secondary airway challenge in mice with established airway disease.

    Churg-Strauss syndrome (CSS) is a granulomatous necrotizing vasculitis of unknown etiology associated with bronchial asthma. Despite affecting small to medium-sized vessels, necrosis of the digits due to vasculitis is extremely rare. We report a case of CSS with necrosis of the toe tips. A 37-year-old woman with asthma, who had been diagnosed with CSS 2 years ago, was admitted to our hospital with an exacerbation of CSS. The patient had a high grade fever and complained of abdominal pain and numbness of the lower extremities. Blood examination revealed marked eosinophilia. The fever pattern, abdominal pain and blood eosinophilia showed improvement by combination treatment with prednisolone and cyclophosphamide. However, the color of her right toe tips changed, and necrosis finally resulted despite antithrombotic therapy. Arteriography showed narrowing of the dorsalis pedis artery and of the more peripheral arteries of her right leg. Stump plasty with negative pressure dressing therapy for the toe tips, but not amputation, was done to preserve the leg function. While numbness of the extremities remained, no recurrence of necrosis was seen. Clinicians need to be aware that rare complications of CSS, including necrosis of the digits, can occur.

    Background: Inhaled corticosteroid (ICS) will be effective if used properly. Inadequate intake may result in insufficiency, such as for elderly asthmatics, in particular, for use of dry powder inhalers. Methods: 312 asthmatics treated with ICS for at least 6 months in the 6 facilities belonging to the Chugoku Shikoku Adult Asthma Research Forum were subject to investigation of the peak inspiratory flow (PIF) measured using In-check® and related factors. Results: Nine (2.8%) patients were considered to have insufficient intake. By multivariate analysis, PIF (L/min) prediction formula was as follows: 79.0 + 0.19*peak expiratory flow (PEF: L/min) + 22.9*FVC (L) - 0.68*onset age (years) + 34.7*gender (male, 1
    female, 0) + 16.1*V50/V25, [r∧2 = 0.677, p&lt
    0.0001]. Using cluster analysis with Euclidean distance and Ward's method, the PIF without an adaptor was included in the same category as height and PEF, and the PIF with an adaptor was included in the same category as %FVC and %FEV 10. Conclusion: The cases with insufficient PIF are few but present. Adequate device selection and inhalation guidance may be important. The meaning of PIF differs depending on whether or not an adaptor is present. Further investigation of intake is considered necessary. ©2011 Japanese Society of Allergology.

    Invariant NKT cells (iNKT cells) play a pivotal role in the development of allergen-induced airway hyperresponsiveness (AHR) and inflammation. However, it is unclear what role they play in the initiation (sensitization) phase as opposed to the effector (challenge) phase. The role of iNKT cells during sensitization was examined by determining the response of mice to intratracheal transfer of OVA-pulsed or OVA-alpha-galactosylceramide (OVA/alpha GalCer)-pulsed bone marrow-derived dendritic cells (BMDCs) prior to allergen challenge. Wild-type (WT) recipients of OVA-BMDCs developed AHR, increased airway eosinophilia, and increased levels of Th2 cytokines in bronchoalveolar lavage fluid, whereas recipients of OVA/alpha GalCer BMDCs failed to do so. In contrast, transfer of these same OVA/alpha GalCer BMDCs into IFN-gamma-deficient (IFN-gamma(-/-)) mice enhanced the development of these lung allergic responses, which was reversed by exogenous IFN-gamma treatment following OVA-BMDC transfer. Further, J alpha 18deficient recipients, which lack iNKT cells, developed the full spectrum of lung allergic responses following reconstitution with highly purified WT liver or spleen iNKT cells and transfer of OVA-BMDCs, whereas reconstituted recipients of OVA/alpha GalCer BMDCs failed to do so. Transfer of iNKT cells from IFN-gamma(-/-) mice restored the development of these responses in J alpha 18-deficient recipients following OVA-BMDC transfer; the responses were enhanced following OVA/alpha GalCer BMDC transfer. iNKT cells from these IFN-gamma(-/-) mice produced higher levels of IL-13 in vitro compared with WT iNKT cells. These data identify IFN-gamma as playing a critical role in dictating the consequences of iNKT cell activation in the initiation phase of the development of AHR and airway inflammation.

    Propionibacterium acnes has been implicated as an etiologic agent of sarcoidosis since the isolation of this bacterium from sarcoid lesions. We experimentally produced a murine pulmonary granuloma model using P. acnes with several features that simulate sarcoidosis. Mice were sensitized with heat-killed P. acnes and complete Freund's adjuvant and were subsequently challenged with heat-killed P. acnes at 2-week intervals. P. acnes-challenged mice developed epitheloid cell granulomas in the lungs. These mice showed a pulmonary immune response characterized by an increased number of T-lymphocytes, especially CD4+ cells, and the ratio of CD4+/CD8+ in bronchoalveolar lavage (BAL) fluid also increased. Furthermore, significant elevations in both angiotensin-converting enzyme (ACE) serum levels and antibody titers against P. acnes were observed. Mice sensitized with P. acnes without complete Freund's adjuvant were capable of forming pulmonary granulomas, which appeared to be caused by indigenous P. acnes. The genome of P. acnes was found in the lungs, BAL cells, hilar lymph nodes, liver, and spleen in non-sensitized mice, which were thought to be germ-free. These results suggest that the immune response against indigenous P. acnes may play an important role in the pathogenesis of granuloma formation in a murine model.

    Idiopathic pulmonary hemosiderosis (IPH) is one of the rare causes of diffuse alveolar hemorrhage (DAH), and usually occurs in children. The mechanism underlying this disease development has not been defined. During the acute phase, death due to massive alveolar hemorrhage and subsequent severe respiratory failure with multiple organ failure often occurs. We report a case of IPH which occurred in an advanced-aged adult during following thyroidectomy for chronic thyroiditis. Following surgery this 83-year-old male developed acute onset dyspnea and pulmonary hemorrhage. In a search for underlying causes, no disorders were found and the only finding was the presence of anti-thyroid antibody. Systemic corticosteroid therapy was effective and he fully recovered. To our knowledge, this is the second documentation of IPH in association with chronic thyroiditis. © 2009 Elsevier Ltd.

    Dendritic cells (DCs) are considered to be the most efficient antigen-presenting cells. Intratracheal administration of allergen-pulsed bone marrow-derived dendritic cells (BMDCs) before allergen challenge induces airway hyperresponsiveness (AHR) and inflammation. Ovalbumin (OVA)-pulsed BMDCs from wild-type (WT) mice were transferred into naive WT, CD4(-/-), CD8(-/-), or IL-13(-/-) mice. Two days (short protocol) or 10 days (long protocol) after BMDC transfer, mice were challenged with 1% OVA for 3 days and assayed 2 days later. Transfer of OVA-primed BMDCs into BALB/c or C57BL/6 mice elicited AHR in both protocols. Airway eosinophilia, Th2 cytokines, or goblet cell metaplasia were increased in the long but not short protocol. Lung T cells from both protocols produced Th2 cytokines in response to OVA in vitro. Carboxyfluorescein diacetate succinimidylester-labeled BMDCs were observed in bronchoalveolar lavage (BAL) fluid and lung parenchyma at early time points, and were detected in draining lymph nodes 48 hours after transfer. CD8(-/-) mice developed AHR comparable to WT mice in the short protocol, but decreased levels of AHR, airway eosinophilia, Th2 cytokines in BAL fluid, and goblet cell metaplasia compared with WT mice in the long protocol. CD4(-/-) or IL-13(-/-) mice did not develop AHR or airway inflammation in either protocol. These data suggest that allergen-pulsed BMDCs initiate development of AHR that is dependent initially on CD4(+) T cells, and at later time periods on CD8+ T cells and IL-13. Thus, the timing of allergen challenge after transfer of allergen-pulsed BMDC affects the development of AHR and airway inflammation.

    Suppressing the abnormalities associated with asthma has been difficult to accomplish using immunotherapy or vaccination once the disease is established. The effector cells necessary for effective immunization/vaccination and immunotherapy of asthma are also not well understood. Therefore, we vaccinated allergen (OVA)-sensitized mice to determine whether therapeutic immunization could suppress airway hyperresponsiveness (AHR) and inflammation and to identify key immune effector cells and cytokines. Mice were immunized with a vaccine comprised of Ag and cationic liposome-DNA complexes (CLDC), a vaccine which has previously been shown to elicit strong CD4(+) and CD8(+) T cell responses and activation of Th1 immunity. We showed that immunization with the OVA-CLDC vaccine significantly suppressed AHR, eosinophilia, goblet cell metaplasia, and Th2 cytokine production. In contrast, immunization with CLDC alone suppressed eosinophilia and Th2 cytokine production, but failed to suppress AHR and goblet cell changes. Using adoptive transfer experiments, we found that suppression of AHR was mediated by Ag-specific CD8(+) T cells and was dependent on IFN-gamma production by the transferred T cells. Thus, we conclude that generation of strong, allergen-specific CD8(+) T cell responses by immunization may be capable of suppressing AHR and allergic airway inflammation, even in previously sensitized and challenged mice.

    Previous studies have shown that leukotriene B4 (LTB4), a proinflammatory lipid mediator, is linked to the development of airway hyperresponsiveness through the accumulation of IL-13-producing CD8+ T cells, which express a high affinity receptor for LTB4, BLT1 (Miyahara et al., Am J Respir Crit Care Med 2005;172:161-167; J Immunol 2005;174:4979-4984). By using leukotriene A4 hydrolase-deficient (LTA4H-/-) mice, which fail to synthesize LTB4, we determined the role of this lipid mediator in allergen-induced airway responses. Two approaches were used. In the first, LTA4H-/- mice and wild-type (LTA4H+/+) mice were systemically sensitized and challenged via the airways to ovalbumin. In the second, mice were passively sensitized with anti-ovalbumin IgE and exposed to ovalbumin via the airways. Mast cells were generated from bone marrow of LTA4H+/+ mice or LTA4H-/- mice. After active sensitization and challenge, LTA4H-/- mice showed significantly lower airway hyperresponsiveness compared with LTA4H+/+ mice, and eosinophil numbers and IL-13 levels in the bronchoalveoloar lavage, of LTA4H-/- mice were also significantly lower. LTA4H-/- mice also showed decreased airway reactivity after passive sensitization and challenge. After LTA4H+/+ mast cell transfer, LTA4H-/- mice showed increased airway reactivity after passive sensitization and challenge, but not after systemic sensitization and challenge. These data confirm the important role for LTB4 in the development of altered airway responses and suggest that LTB4 secretion from mast cells is critical to eliciting increased airway reactivity after passive sensitization with allergen-specific IgE.

    Allergic airway hyperresponsiveness (AHR) in OVA-sensitized and challenged mice, mediated by allergen-specific Th2 cells and Th2-like invariant NKT (iNKT) cells, develops under the influence of enhancing and inhibitory gamma delta T cells. The AHR-enhancing cells belong to the V gamma 1(+) gamma delta T cell subset, cells that are capable of increasing IL-5 and IL-13 levels in the airways in a manner like Th2 cells. They also synergize with iNKT cells in mediating AHR. However, unlike Th2 cells, the AHR enhancers arise in untreated mice, and we show here that they exhibit their functional bias already as thymocytes, at an HSA(high) maturational stage. In further contrast to Th2 cells and also unlike iNKT cells, they could not be stimulated to produce IL-4 and IL-13, consistent with their synergistic dependence on iNKT cells in mediating AHR. Mice deficient in IFN-gamma, TNFRp75, or IL-4 did not produce these AHR-enhancing gamma delta T cells, but in the absence of IFN-gamma, spontaneous development of these cells was restored by adoptive transfer of IFN-gamma-competent dendritic cells from untreated donors. The i.p. injection of OVA/aluminum hydroxide restored development of the AHR enhancers in all of the mutant strains, indicating that the enhancers still can be induced when they fail to develop spontaneously, and that they themselves need not express TNFRp75, IFN-gamma, or IL-4 to exert their function. We conclude that both the development and the cytokine potential of the AHR-enhancing gamma delta T cells differs critically from that of Th2 cells and NKT cells, despite similar influences of these cell populations on AHR.

    Background: Ligation of the leukotriene B-4 (LTB4) receptor I on effector memory CD8(+) T cells by LTB4 is important for the recruitment of CD8(+) T cells into the airways, which appears central to the induction of airway hyperresponsiveness (AHR) and allergic inflammation. Phosphorylation of extracellular signal-regulated kinase (ERK) is important in activation and cytokine production from many cell types.
    Objective: The roles of ERKs in effector CD8(+) T-cell function and on CD8(+) T cell-mediated AHR were determined.
    Methods: Effector CD8(+) T cells were generated from OVA(257.264) (SIINFEKL) peptide-primed mononuclear cells from OT-1 mice. The effects of U0126, an ERK inhibitor, on effector CD8(+) T-cell function and on CD8(+) T cell-mediated AHR and allergic inflammation were examined.
    Results: Pretreatment of effector CD8(+) T cells with U0126 suppressed anti-CD3/anti-CD28-induced ERK1/2 phosphorylation and cytokine production, but did not affect LTB4-induced Ca2+ mobilization or chemotaxis. Adoptive transfer of U0126-treated CD8(+) T cells into sensitized mice before secondary allergen challenge resulted in significant decreases in AHR, eosinophilic inflammation, goblet cell metaplasia, and IL-5 and IL-13 levels in bronchoalveolar lavage fluid of recipient mice. The number of transferred CD8(+) T cells accumulating in bronchoalveolar lavage fluid or lungs was unaffected by treatment.
    Conclusion: ERK1/2-dependent pathways are essential for the effector functions of CD8(+) T cells, including T(H)2 cytokine production, allergic inflammation, and development of AHR. Inhibition of ERK1/2 signaling has potential therapeutic benefit in preventing CD8(+) T cell-mediated AHR. (J Allergy Clin Immunol 2009;123:249-57.)

    Dendritic cells (DC) are important APCs that control allergen-induced airway responses by interacting directly with T cells. Leukotriene B(4) (LTB(4)), interacting with its high-affinity receptor, LTB4 receptor 1 (BLT1), is known to attract and activate leukocytes during inflammation. We have previously shown that BLT1 expression on Ag-primed T cells is required for the development of airway hyperresponsiveness (AHR; Miyahara et al. 2005. Am. J. Respir. Crit. Care Med. 172: 161-167). However, the role for the LTB(4)-BLT1 pathway in DC function in allergen-induced airway responses has not been defined. Bone marrow-derived DCs (BMDC) were generated. Naive BALB/c mice received OVA-pulsed BLT1-deficient (BLTI(-/-)) BMDCs or wild-type BMDCs intratracheally and were then challenged with OVA for 3 days. Airway responses were monitored 48 h after the last allergen challenge. BLTI(-/-) BMDCs showed normal maturation judged from surface expression of CD markers. Compared with recipients of wild-type BMDCs, mice that received BLT1(-/-) BMDCs developed significantly lower AHR to inhaled methacholine, lower goblet cell metaplasia, and eosinophilic infiltration in the airways and decreased levels of Th2 type cytokines in the bronchoalveolar lavage fluid. Migration of BLTI(-/-) BMDCs into peribronchial lymph nodes was significantly impaired compared with BLTI(+/+) BMDCs after intratracheal instillation. These data suggest that BLTI expression on DCs is required for migration of DCs to regional lymph nodes as well as in the development of AHR and airway inflammation.

    Airway hyperresponsiveness (AHR), a hallmark of asthma and several other diseases, can be modulated by gamma delta T cells. In mice sensitized and challenged with OVA, AHR depends on allergen-specific alpha beta T cells; but V gamma 1(+) gamma delta T cells spontaneously enhance AHR, whereas V gamma 4(+) gamma delta T cells, after being induced by airway challenge, suppress AHR. The activity of these gamma delta T cell modulators is allergen nonspecific, and how they develop is unclear. We now show that CD8 is essential for the development of both the AHR suppressor and enhancer gamma delta T cells, although neither type needs to express CD8 itself. Both cell types encounter CD8-expressing non-T cells in the spleen, and their functional development in an otherwise CD8-negative environment can be restored with transferred spleen cell preparations containing CD8(+) dendritic cells (DCs), but not CD8(+) T cells or CD8-DCs. Our findings suggest that CD8(+) DCs in the lymphoid tissues enable an early step in the development of gamma delta T cells through direct cell contact. DC-expressed CD8 might take part in this interaction.

    Activation of CD4(+)CD25(+)Foxp3(+) naturally occurring regulatory T cells (nTregs) resulting in suppression of lung allergic responses requires interaction of MHC class I on nTregs and CD8. In the absence of CD8 (CD8(-/-) recipients), transferred nTregs restored airway hyperresponsiveness, eosinophilic inflammation, and IL-13 levels following allergen exposure. Enhancement of lung allergic responses was accompanied by reduced expression of Foxp3 and increased expression of IL-13 in the transferred nTregs. In CD8(-/-) recipients pretreated with glucocorticoid-induced TNFR-related protein-ligand Ab, the transferred nTregs maintained high levels of Foxp3 and did not result in altered lung responses. Thus, the regulatory function of nTregs can be subverted by reducing the expression of Foxp3 and following signaling through glucocorticoid-induced TNFR-related protein are converted nTregs into IL-13-producing CD4(+) T cells mediating lung allergic responses.

    The female hormone estrogen is an important factor in the regulation of airway function and inflammation, and sex differences in the prevalence of asthma are well described. Using an animal model, we determined how sex differences may underlie the development of altered airway function in response to allergen exposure. We compared sex differences in the development of airway hyperresponsiveness (AHR) after allergen exposure exclusively via the airways. Ovalbumin (OVA) was administered by nebulization on 10 consecutive days in BALB/c mice. After methacholine challenge, significant AHR developed in male mice but not in female mice. Ovariectomized female mice showed significant AHR after 10-day OVA inhalation. IC11182,780, an estrogen antagonist, similarly enhanced airway responsiveness even when administered 1 hour before assay. In contrast, 17 beta-estradiol dose-dependently suppressed AHR in male mice. In all cases, airway responsiveness was inhibited by the administration of a neurokinin I receptor antagonist. These results demonstrate that sex differences in 10-day OVA-induced AHR are due to endogenous estrogen, which negatively regulates airway responsiveness in female mice. Cumulatively, the results suggest that endogenous estrogen may regulate the neurokinin 1-dependent prejunctional activation of airway smooth muscle in allergen-exposed mice.

    Background: Leukotriene B-4 (LTB4) is a potent inflammatory lipid mediator that binds to LTB4 receptor 1 (BLT1). Ligation of BLT1 by LTB4 plays an important role in the recruitment of effector memory CD8(+) T cells into the airways of sensitized and challenged mice.
    Objectives: The effects of the corticosteroid dexamethasone (DEX) on BLT1-expressing effector memory CD8(+) T cells and effector memory CD8(+) T cell-mediated airway hyperresponsiveness (AHR) and allergic inflammation were determined.
    Methods: Effector memory CD8(+) T cells were generated from ovalbumin(257-264)-primed mononuclear cells from OT-1 mice in the presence of IL-2. In some cultures DEX was added. The effects of DEX on BLT1 expression, LTB4-induced Ca2+ influx, phosphorylation of extracellular signal-regulated kinase 1/2, chemotaxis, and effector memory CD8(+) T cell-mediated AHR were examined.
    Results: DEX-treated effector memory CD8(+) T cells showed significant increases in surface expression of BLT1, LTB4-induced intracellular Ca2+ influx, phosphorylation of extracellular signal-regulated kinase 1/2, and chemotaxis. Upregulation of BLT1 by DEX was accompanied by increased IL-2 receptor expression. Adoptive transfer of DEX-treated effector memory CD8(+) T cells into ovalbumin-sensitized and ovalbumin-challenged CD8(-/-) mice resulted in significant increases in AHR, allergic inflammation, goblet cell metaplasia, and numbers of both CD8(+) and CD4(+) T cells in the bronchoalveolar lavage fluid and lungs.
    Conclusions: Corticosteroids upregulate BLT1 on effector memory CD8(+) T cells and related signaling pathways and potentiate allergic airway inflammation and AHR induced by these cells.

    Methods: Sensitized wild-type and Fc epsilon RI-deficient (FC epsilon RI(-/-)) mice were exposed to allergen for 3, 5, or 12 days. As indicators of nasal reactivity, respiratory frequency and nasal resistance were monitored.
    Results: Sensitized mice exposed to 3 days of nasal allergen challenge showed a nonspecific early-phase response. As the number of allergen exposures increased, there was progressive diminution in nonspecific responses with increased allergen-specific early-phase responses and a late-phase response. Sensitized Fc epsilon RI(-/-) mice did not develop nonspecific nasal responses or late-phase responses, but transfer of in vitro-differentiated wild-type mast cells into Fc epsilon RI(-/-) mice restored nonspecific early-phase nasal responses but not the late-phase response.
    Conclusion: These data identify the nonspecific nasal response as a major contributor to the early-phase response, especially during initial allergen exposure, and is dependent on mast cells. Increasing allergen exposure results in increasing allergen-specific responses, converting the nonspecific early-phase response to a late-phase response that is allergen-specific and mast cell-independent.

    Rationale. Severe respiratory syncytial virus (RSV) bronchiolitis has been associated with deficient IFN-gamma production in humans, but the role of this cytokine in determining the outcome of reinfection is unknown.
    Objectives: To define the role of IFN-gamma in the development of RSV-mediated airway hype rresponsiveness (AHR) and lung histopathology in mice.
    Methods: Wild-type (WT) and IFN-gamma knockout mice were infected with RSV in the newborn or weaning stages and reinfected 5 weeks later. Airway responses were assessed on Day 6 after the primary or secondary infection.
    Measurements and Main Results: Both WT and IFN-gamma knockout mice developed similar levels of AHR and airway inflammation after primary infection. After reinfection, IFN-gamma knockout mice, but not WT mice, developed AHR, airway eosinophilia, and mucus hyperproduction. Intranasal administration of IFN-gamma during primary infection but not during reinfection prevented the development of these altered airway responses on reinfection in IFN-gamma knockout mice. Adoptive transfer of WT T cells into IFN-gamma knockout mice before primary infection restored IFN-gamma production in the lungs and prevented the development of altered airway responses on reinfection. Treatment of mice with IFN-gamma during primary neonatal infection prevented the enhancement of AHR and the development of airway eosinophilia and mucus hyperproduction on reinfection.
    Conclusions: IFN-gamma production during primary RSV infection is critical to the development of protection against AHR and lung histopathology on reinfection. Provision of IFN-gamma during primary infection in infancy may be a potential therapeutic approach to alter the course of RSV-mediated long-term sequelae.

    Leukotriene B4 (LTB4) is a lipid mediator with potent chemoattractant properties and that is rapidly generated from activated innate immune cells such as neutrophils, macrophages, and mast cells. Elevated levels of LTB4 have been reported in various allergic diseases and these levels have been related to disease activity and response to treatment. Recent studies using LTB4 receptor-1 (BLT1) antagonists or BLT1-deficient mice have revealed that ligation of BLT1 by LTB4 is important for the activation and recruitment of inflammatory cells including neutrophils, eosinophils, imonocytes/macrophages, mast cells, dendritic cells, and more recently, effector T cells to inflamed tissues in various inflammatory diseases. The LTB4/BLT1 pathway appears to play an important role in the pathogenesis of severe persistent asthma, aspirin- and exercise-induced asthma, allergic rhinitis, and atopic dermatitis together with other mediators including cysteinyl leukotrienes, cytokines, and chemokines. LTB4 production is in general resistant to corticosteroid treatment. In fact, corticosteroids can upregulate BLT1 expression on corticosteroid-resistant inflammatory cells such as neutrophils, monocytes, and effector memory CD8+ T cells. As a result, this corticosteroid-resistant LTB4/BLT1 pathway may contribute to the development of inflammation in allergic diseases that do not respond to the introduction of corticosteroids. Inhibition of this pathway has potential therapeutic benefit in various allergic diseases that have involvement of corticosteroid-insensitivity. © 2008 Japanese Society of Allergology.

    Mice sensitized and challenged with OVA were used to investigate the role of innate T cells in the development of allergic airway hyperresponsiveness (AHR). AHR, but not eosinophilic airway inflammation, was induced in T cell-deficient mice by small numbers of cotransferred gamma(delta) T cells and invariant NKT cells, whereas either cell type alone was not effective. Only V gamma 1(+)V delta 5(+) gamma delta T cells enhanced AHR. Surprisingly, OVA-specific alpha beta T cells were not required, revealing a pathway of AHR development mediated entirely by innate T cells. The data suggest that lymphocytic synergism, which is key to the Ag-specific adaptive immune response, is also intrinsic to T cell-dependent innate responses.

    CD4(+) T cells, particularly Th2 cells, play a pivotal role in allergic airway inflammation. However, the requirements for interactions between CD4+ and CD8(+) T cells in airway allergic inflammation have not been delineated. Sensitized and challenged OT-1 mice in which CD8(+) T cells expressing the transgene for the OVA(257-264) peptide (SIINFEKL) failed to develop airway hyperresponsiveness (AHR), airway eosinophilia, Th2 cytokine elevation, or goblet cell metaplasia. OT-1 mice that received naive CD4(+)IL-4(+) T cells but not CD4(+)IL-4(-) T cells before sensitization developed all of these responses to the same degree as wild-type mice. Moreover, recipients of CD4(+)IL-4(+) T cells developed significant increases in the number of CD8(+)IL-13(+) T cells in the lung, whereas sensitized OT-1 mice that received primed CD4(+) T cells just before challenge failed to develop these responses. Sensitized CD8-deficient mice that received CD8(+) T cells from OT-1 mice that received naive CD4(+) T cells before sensitization increased AHR and eosinophil numbers in bronchoalveolar lavage fluid when challenged with allergen. In contrast, sensitized CD8-deficient mice receiving CD8(+) T cells from OT-1 mice without CD4(+) T cells developed reduced AHR and eosinophil numbers in bronchoalveolar lavage fluid when challenged. These data suggest that interactions between CD4(+) and CD8(+) T cells, in part through IL-4 during the sensitization phase, are essential to the development of CD8(+)IL-13(+) T cell-dependent AHR and airway allergic inflammation.

    Naturally occurring Foxp3(+)CD4(+)CD25(+) T cells (nTregs) isolated from lungs of naive mice regulate allergic airway hyperresponsiveness (AHR) and inflammation. Here, we demonstrate the critical requirement for engagement of MHC class I on CD4(+)CD25(+) T cells by CD8 for the functional activation of these nTregs. Suppression of allergen-induced AHR and inflammation by nTregs was abolished in mice treated with anti-CD8. Correspondingly, decreased levels of IL-10 and TGF-beta and increased levels of Th2 cytokines in bronchoalveolar lavage were detected in these treated mice. Similarly, nTregs isolated from beta 2m(-/-) mice or from mice treated with anti-MHC I antibody in vitro before intratracheal transfer failed to modulate AHR or inflammation. Coculture of nTregs with CD8(+) T cells increased IL-10 and TGF-beta. Addition of anti-MHC I or anti-CD8 reduced IL-10 and TGF-beta. These results demonstrate that functional activation of nTregs requires the interaction between MHC I on CD4(+)CD25(+) T cells and CD8.

    Rationale: Arhgef1 is an intracellular protein, expressed by hematopoietic cells, that regulates signaling by both G protein-coupled receptors and RhoA, and, consequently, is required for appropriate migration and adhesion of diverse leukocyte populations. Objectives: To evaluate a possible contribution for Arhgef1 in the development of airway inflammation and airway hyperreactivity. Methods: Arhgef1-deficient (Arhgef1(-/-)) and wild-type (WT) mice were sensitized and airway challenged, followed by measurement of airway responsiveness to inhaled methacholine. Inflammation was assessed by several parameters that included flow cytometric analysis and histology. Arhgef1-deficient recipients were reconstituted with WT T lymphocytes before sensitization and challenge, and again measured for airway responsiveness and inflammation. Cytokine production in response to specific antigen was measured in cultures of isolated leukocytes from lung and spleen and compared with the levels generated in lung and spleen explant cultures. Measurements and Main Results: Arhgef1(-/-) mice display significantly reduced airway hyperreactivity, Th2 cytokine production, and lung inflammation, despite intact systemic immunity. After airway challenge of Arhgef1(-/-) mice, antigen-specific T cells were present in mutant lungs, but were found to interact with CD11c(+) cells at a significantly reduced frequency. Adoptive transfer of WTTcells into Arhgef1(-/-) mice restored airway hyperreactivity and inflammation. Conclusions: These data demonstrate that T cells depend on Arhgef1 to promote lung inflammation. Moreover, a deficiency in Arhgef1 results in reduced T cell-CD11c(+) antigen-presenting cell interaction, and likely underscores the inability of Arhgef1(-/-) mice to mount an adaptive immune response to airway challenge.

    Background: IL-10 affects dendritic cell (DC) function, but the effects on airway hyperresponsiveness (AHR) and inflammation are not defined.
    Objective: We sought to determine the importance of IL-10 in regulating DC function in allergen-induced AHR and airway inflammation.
    Methods: DCs were generated from bone marrow in the presence or absence of IL-10. In vivo IL-10-treated DCs from IL-10(+/+) and IL-10(-/-) donors pulsed with ovalbumin (OVA) were transferred to naive or sensitized mice before challenge. In recipient mice AHR, cytokine levels, cell composition of bronchoalveolar lavage (BAL) fluid, and lung histology were monitored.
    Results: In vitro, IL-10-treated DCs expressed lower levels of CD11c, CD80, and CD86; expressed lower levels of IL-12; and suppressed T(H)2 cytokine production. In vivo, after transfer of OVA-pulsed IL-10-treated DCs, naive mice did not have AHR, airway eosinophilia, T(H)2 cytokine increase in BAL fluid, or goblet cell metaplasia when challenged, and in sensitized and challenged mice IL-10-treated I)Cs suppressed these responses. Levels of IL-10 in BAL fluid and numbers of lung CD4(+)IL-10(+) T cells were increased in mice that received OVA-pulsed IL-10-treated DCs. Transfer of IL-10-treated DCs from IL-10-deficient mice were ineffective in suppressing the responses in sensitized and challenged mice.
    Conclusions: These data demonstrate that IL-10-treated DCs are potent suppressors of the development of AHR, inflammation, and T(H)2 cytokine production; these regulatory functions are at least in part through the induction of endogenous (DQ production of IL-10. Clinical implications: Modification of DC function by IL-10 can attenuate lung allergic responses, including the development of AHR.

    IL-18 is known to induce IFN-gamma production, which is enhanced when combined with IL-2. In the present study, we investigated whether the combination of exogenous IL-2 and IL-18 alters airway hyperresponsiveness (AHR) and airway inflammation. Sensitized mice exposed to ovalbumin (OVA) challenge developed AHR, inflammatory cells in the bronchoalveolar lavage (BAL) fluid, and increases in levels of Th2 cytokines and goblet cell numbers. The combination of IL-2 and IL-18, but neither alone, prevented these changes while increasing levels of IL-12 and IFN-gamma. The combination of IL-2 and IL-18 was ineffective in IFN-gamma-deficient and signal transducer and activator of transcription (STAT)4-deficient mice. Flow cytometry analysis showed significant increases in numbers of IFN-gamma-positive natural killer (NK) cells in the lung after treatment with the combination therapy, and transfer of lung NK cells isolated from sensitized and challenged mice treated with the combination significantly suppressed AHR and BAL eosinophilia. These data demonstrate that the combination of IL-2 and IL-18 prevents AHR and airway inflammation, likely through IL-12-mediated induction of IFN-gamma production in NK cells.

    Peripheral tolerance to allergens is mediated in large part by the naturally occurring lung CD4(+)CD25(+) T cells, but their effects on allergen-induced airway responsiveness have not been well defined. Intratracheal, but not i.v., administration of naive lung CD4(+)CD25(+) T cells before allergen challenge of sensitized mice, similar to the administration of the combination of rIL-10 and rTGF-beta, resulted in reduced airway hyperresponsiveness (AHR) and inflammation, lower levels of Th2 cytokines, higher levels of IL-10 and TGF-beta, and less severe lung histopathology. Significantly, CD4(+)CD25(+) T cells isolated from IL-10(-/-) mice had no effect on AHR and inflammation, but when incubated with rIL-10 before transfer, suppressed AHR, and inflammation, and was associated with elevated levels of bronchoalveolar lavage TGF-beta levels. By analogy, anti-TGF-beta treatment reduced regulatory T cell activity. These data identify naturally occurring lung CD4(+)CD25(+) T cells as capable of regulating lung allergic responses in an IL-10- and TGF-beta-dependent manner.

    The FeR common y-chain (FcRy) is an essential component of the receptors Fe epsilon RI, Fc gamma RI, and Fc gamma RIII, which are expressed on many inflammatory cell types. The role of these receptors in the initiation or maintenance of allergic inflammation has not been well defined. FcR gamma-deficient (FcRy(-/-)) and control (wild-type (WT)), mice were sensitized and subsequently challenged with OVA. Following sensitization and challenge to OVA, FeRy-deficient (FcRy(-/-)) mice developed comparable levels of IgE and IgG1 as WT mice. However, numbers of eosinophils, levels of IL-5, IL-13, and eotaxin in bronchoalveolar lavage fluid, and mononuclear cell (MNC) proliferative responses to OVA were significantly reduced, as was airway hyperresponsiveness (AHR) to inhaled methacholine. Reconstitution of FeRy(-/-) mice with whole spleen MNC from WT mice before sensitization restored development of AHR and the numbers of eosinophils in bronchoalveolar lavage fluid; reconstitution after sensitization but before OVA challenge only partially restored these responses. These responses were also restored when FcRy(-/-) mice received T cell-depleted MNC, T and B cell-depleted MNC, or bone marrow-derived dendritic cells before sensitization from FcR(+/+) or Fe gamma RIII-deficient but not FcRy(-/-) mice. The expression levels of Fc gamma RIV on bone marrow-derived dendritic cells from FcR(+/+) mice were found to be low. These results demonstrate that expression of FcR gamma, most likely Fc gamma RI, on APCs is important during the sensitization phase for the development of allergic airway inflammation and AHR.

    Background: The pathophysiology of the early- and late-phase nasal response to allergen challenge is not completely defined. Recent technical advances enable direct monitoring of these responses in mice.
    Objective: IL-13 is detected in the nasal membranes of both human beings and mice with allergic rhinitis, but its role in disease pathogenesis is unclear. We measured early and late nasal allergic responses after treatment with soluble IL-13R alpha 2-IgG fusion protein (sIL-13R alpha 2-Fc), and in IL-13-deficient mice (IL-13(-/-)).
    Methods: IL-13(-/-) mice (BALB/c background) and wild-type mice were sensitized to ovalbumin by intraperitoneal injection and then challenged intranasally with ovalbumin without sedation. The sIL-13R alpha 2-Fc or control human IgG was administered by intraperitoneal (i.p.) injection 24 hours and 1 hour before each ovalbumin challenge. Early nasal responses after the 4th ovalbumin challenge and late nasal responses 24 hours after the 6th ovalbumin challenge were assessed. Results: Sensitized/challenged wild-type mice treated with sIL-13R alpha 2-Fc or IL-13(-/-) mice demonstrated significantly reduced late nasal responses in face of persistent nasal tissue eosinophilia; the early nasal response was little affected by targeting IL-13. Goblet cell hyperplasia was not detected in nasal membranes.
    Conclusion: The data indicate that IL-13 is a major contributor to the development of a late nasal response with little influence on the early response, and without affecting nasal eosinophilic inflammation. Inhibition of IL-13 may have an important therapeutic application in preventing the persistent nasal blockage in allergic rhinitis.
    Clinical implications: Current therapies for allergic rhinitis may not take into account the important differences in the pathophysiology of the early and late responses and the important role of IL-13 in sustaining chronic nasal congestion and obstruction.

C57BL/6 mice, sensitized by injection of ovalbumin (OVA) on Days I and 14, were challenged with OVA on Days 28, 29, and 30 (3 challenges, short-term-challenge model) or on Days 28, 29, 30, 36, 40, 44, and 48 (7 challenges, repeated-challenge model) and evaluated 48 h later. Anti-mouse RANTES was given intravenously, and recombinant mouse RANTES or PBS was given intratracheally. These reagents were given on Days 28, 29, and 30 in the short-term-challenge study and on Days 44 and 48 in the repeated-challenge study. After short-term challenge, there were no effects after administration of anti-RANTES or RANTES. In the repeated-challenge study, although control mice showed a decrease in airway hyperresponsiveness, administration of anti-RANTES sustained and enhanced airway hyperresponsiveness and increased goblet cell numbers. In contrast, administration of RANTES normalized airway function but reduced goblet cell numbers. IL-12 and IFN-gamma levels in BAL decreased in the anti-RANTES group and increased in the RANTES group. IFN-gamma-producing CD4 T cells in lung, and IFN-gamma production from lung T cells in response to OVA in the anti-RANTES group, were significantly decreased but were increased in the RANTES group. Anti-IFN-gamma administered with RANTES, decreased the effects of RANTES on AHR after repeated challenge. These data indicate that RANTES plays a role in the regulation of airway function after repeated allergen challenge, in part through modulation of levels of IFN-gamma and IL-12.

    LTB4, a proinflammatory lipid mediator generated from arachidonic acid through the action of 5-lipoxygenase, has been known for over two decades and is implicated in a wide variety of inflammatory disorders. BLT1, a G-protein-coupled receptor, has recently been identified as a high affinity receptor specific for LTB4. Recent studies in allergen-induced airway hyperresponsiveness and inflammation using mice lacking BLT1 have shown crucial new roles for leukotriene B4 and BLT1 in Th2 cytokine IL-13 production from lung T cells and recruitment of antigen-specific effector CD8+ T cells, suggesting novel mechanisms for their actions. The leukotriene B4-BLT1 pathway is an important target for the treatment of bronchial asthma.<br>

    Exposure to inhaled allergens leads to increases in airway hyper-responsiveness (AHR) and inflammation, associated with increased levels of biologically active fragments derived from the complement C3 and C5 family of proteins. Further, complement activation during allergen challenge in sensitized animals is necessary for the development of AHR and airway inflammation. To define the complement pathway involved, we studied mice deficient in complement factor 4 (C4-/-), a critical component of the classical pathway, or factor B (fB-/-), an essential protein in the alternative complement pathway. WT, C4-/-, and fB-/- mice were sensitized to ovalbumin and subsequently exposed to nebulized ovalbumin (1% in saline) on 3 consecutive days. After allergen sensitization and challenge, fB-/- mice demonstrated significantly lower airway responsiveness to methacholine and less airway inflammation. In contrast, C4-/- mice showed no reduction in AHR and airway inflammation compared with WT mice. Tissue inflammation, goblet cell hyperplasia, and IL-4, IL-5, and IL-13 levels in BAL fluid were significantly reduced in fB-/- mice compared with C4-/- and WT mice. The development of AHR and airway inflammation in sensitized fB-/- mice could be restored after intranasal administration of purified factor B before the airway challenge. In addition, administration of a neutralizing anti-factor B mAb to sensitized mice before airway challenge reduced the development of AHR and airway inflammation. These results demonstrate that in sensitized hosts complement activation through the alternative pathway after allergen exposure is critical to the development of AHR and airway inflammation.

    We evaluated the role of Syk, using an inhibitor, on allergen-induced airway hyperresponsiveness (AHR) and airway inflammation in a system shown to be B cell- and mast cell-independent. Sensitization of BALB/c mice with ovalbumin (OVA) and alum after three consecutive OVA challenges resulted in AHR to inhaled methacholine and airway inflammation. The Syk inhibitor R406 (30 mg/kg, administered orally, twice daily) prevented the development of AHR, increases in eosinophils and lymphocytes and IL-13 levels in bronchoalveolar lavage (BAL) fluid, and goblet cell metaplasia when administered after sensitization and before challenge with OVA. Levels of IL-4, IL-5, and IFN-gamma in BAL fluid and allergen-specific antibody levels in serum were not affected by treatment. Because many of these responses may be influenced by dendritic cell function, we investigated the effect of R406 on bone marrow-derived dendritic cell (BMDC) function. Co-culture of BMDC with immune complexes of OVA and IgG anti-OVA together with OVA-sensitized spleen mononuclear cells resulted in increases in IL-13 production. IL-13 production was inhibited if the BMDCs were pretreated with the Syk inhibitor. Intratracheal transfer of immune complex-pulsed BMDCs (but not nonpulsed BMDCs) to naive mice before airway allergen challenge induced the development of AHR and increases in BAL eosinophils and lymphocytes. All of these responses were inhibited if the transferred BMDCs were pretreated with R406. These results demonstrate that Syk inhibition prevents allergen-induced AHR and airway inflammation after systemic sensitization and challenge, at least in part through alteration of DC function.

    Studies in both humans and rodents have suggested that CD8(+) T cells contribute to the development of airway hyperresponsiveness (AHR) and that leukotriene B4 (LTB4) is involved in the chemotaxis of effector CD8(+) T cells (T-EFF) to the lung by virtue of their expression of BLT1, the receptor for LTB4. In the present study, we used a mast cell-CD8-dependent model of AHR to further define the role of BLT1 in CD8(+) T cell-mediated AHR. C57BL/6(+/+) and CD8-deficient (CD8(-/-)) mice were passively sensitized with anti-OVA IgE and exposed to OVA via the airways. Following passive sensitization and allergen exposure, C57BL/6(+/+) mice developed altered airway function, whereas passively sensitized and allergen-exposed CD8(-/-) mice failed to do so. CD8(-/-) mice reconstituted with CD8(+) T-EFF developed AHR in response to challenge. In contrast, CD8(-/-) mice reconstituted with BLT1-deficient effector CD8(+) T cells did not develop AHR. The induction of increased airway responsiveness following transfer of CD8(+) TEFF or in wild-type mice could be blocked by administration of an LTB4 receptor antagonist confirming the role of BLT1 in CD8(+) T cell-mediated AHR. Together, these data define the important role for mast cells and the LTB4-BLT1 pathway in the development of CD8(+) T cell-mediated allergic responses in the lung.

    Rationale: There is conflicting information about the development and resolution of airway inflammation and airway hyperresponsiveness (AHR) after repeated airway exposure to allergen in sensitized mice.
    Methods: Sensitized BALB/c and C57BL/6 mice were exposed to repeated allergen challenge on 3, 7, or I I occasions. Airway function in response to inhaled methacholine was monitored; bronchoalveolar lavage fluid inflammatory cells were counted; and goblet cell metaplasia, peribronchial fibrosis, and smooth muscle hypertrophy were quantitated on tissue sections. Bone marrow-derived dendritic cells were generated after differentiation of bone marrow cells in the presence of growth factors.
    Results: Sensitization to ovalbumin (OVA) in alum, followed by three airway exposures to OVA, induced lung eosinophilia, goblet cell metaplasia, mild peribronchial fibrosis, and peribronchial smooth muscle hypertrophy; increased levels of interleukin (IL)-4, IL-5, IL-13, granulocyte-macrophage colony-stimulating factor, transforming growth factor-beta(1), eotaxin-1, RANTES (regulated on activation, normal T-cell expressed and secreted), and OVA-specific IgG1 and IgE; and resulted in AHR. After seven airway challenges, development of AHR was markedly decreased as was the production of IL-4, IL-5. and IL-13. Levels of IL-10 in both strains and the level of IL-12 in BALB/c mice increased. After 11 challenges, airway eosinophilia and peribronchial fibrosis further declined and the cytokine and chemokine profiles continued to change. At this time point, the number of myeloid dendritic cells and expression of CD80 and CD86 in lungs were decreased compared with three challenges. After 11 challenges, intratracheal instillation of bone marrow-derived dendritic cells restored AHR and airway eosinophilia.
    Conclusions: These data suggest that repeated allergen exposure leads to progressive decreases in AHR and allergic inflammation, through decreases in myeloid dendritic cell numbers.

    Rationale: Spleen tyrosine kinase (Syk) is important for Fc and B-cell receptor-mediated signaling.
    Objective: To determine the activity of a specific Syk inhibitor (11406) on mast cell activation in vitro and on the development of allergen-induced airway hyperresponsiveness (AHR) and inflammation in vivo.
    Methods: AHR and inflammation were induced after 10 d of allergen (ovalbumin [OVA]) exposure exclusively via the airways and in the absence of adjuvant. This approach was previously established to be IgE, Fc epsilon RI, and mast cell dependent. Alternatively, mice were passively sensitized with OVA-specific IgE, followed by limited airway challenge. In vitro, the inhibitor was added to cultures of IgE-sensitized bone marrow-derived mast cells (BMMCs) before crosslinking with allergen.
    Results: The inhibitor prevented OVA-induced degranulation of passively IgE-sensitized murine IBMMCs and inhibited the production of interieukin (IL)-13, tumor necrosis factor a, IL-2, and IL-6 in these sensitized BMMCs. When administered in vivo, R406 inhibited AHR, which developed in BALB/c mice exposed to aerosolized 1% OVA for 10 consecutive d (20 min/d), as well as pulmonary eosinophilia and goblet cell metaplasia. A similar inhibition of AHR was demonstrated in mice passively sensitized with OVA-specific IgE and exposed to limited airway challenge.
    Conclusion: This study delineates a functional role for Syk in the development of mast cell- and IgE-mediated AHR and airway inflammation, and these results indicate that inhibition of Syk may be a target in the treatment of allergic asthma.

    Background: There have been few reports using animal models to study the development of allergic rhinitis. Characterization of such a model in mice would be advantageous given the availability of reagents and gene-manipulated strains.
    Objective: We sought to develop a murine model of allergic rhinitis in the absence of lower airway changes.
    Methods: After sensitization and challenge, both wild-type and Fe epsilon RI-deficient mice were studied for their ability to develop early- and late-phase nasal responses. In the invasive approach, direct measurements of nasal airway resistance (R-NA) were obtained; in the noninvasive approach using whole-body plethysmography, respiratory frequency and expiratory and inspiratory times were monitored. In both approaches, nasal responses were determined either acutely after challenge (early phase) or 24 hours after challenge (late phase).
    Results: After challenge of sensitized mice, R-NA significantly increased. In parallel, respiratory frequency significantly decreased and was highly correlated with the increases in R-NA-Sensitized wild-type mice had an early-phase nasal response and persistent nasal blockage (late-phase response) after allergen challenge. In contrast, sensitized and challenged Fc epsilon RI alpha-chain-deficient mice did not have an early-phase nasal reaction and exhibited reduced nasal blockage and lower IL-13 levels in nasal tissue homogenates.
    Conclusions: These data indicate that Fc epsilon RI is essential to development of an early-phase nasal response and contributes to the development of the late-phase nasal response. These invasive and noninvasive approaches provide new opportunities to evaluate the mechanisms underlying the development of nasal responses to allergen and to assess various therapeutic interventions.

    S-carboxymethylcysteine (S-CMC) has been used as a mucoregulator in respiratory diseases. However, the mechanism of action of S-CMC on allergic airway inflammation has not yet been defined.
    In the present study, BALB/c mice were initially sensitised and challenged to ovalbumin (OVA) and, weeks later, re-challenged with OVA (secondary challenge). S-CMC (5-100 mg.kg(-1)) was administered from 2 days before the secondary challenge through to the day of assay.
    Mice developed airway hyperresponsiveness (AHR) 6 h after the secondary challenge and increased numbers of neutrophils were present in the bronchoalveolar lavage (BAL) fluid. At 72 h after secondary challenge, mice again developed AHR, but the BAL fluid contained large numbers of eosinophils. S-CMC treatment was found to reduce AHR and neutrophilia at 6 h, as well as eosinophilia and AHR at 72 h. These effects appeared to be dose dependent. Goblet cell hyperplasia, observed at 72 h, was reduced by S-CMC. In BAL fluid, increased levels of interferon-gamma, interleukin (IL)-12 and IL-10 and decreased levels of IL-5 and IL-13 were detected.
    In conclusion, the data indicate that S-carboxymethylcysteine is effective in reducing airway hyperresponsiveness and airway inflammation at two distinct phases of the response to the secondary allergen challenge in sensitised mice.

    Respiratory syncytial virus (RSV) infection in early life is suspected to play a role in the development of postbronchiolitis wheezing and asthma. Reinfection is common at all ages, but factors that determine the development of altered airway function after reinfection are not well understood. This study was conducted in a mouse model to define the role of age in determining the consequences on airway function after reinfection. Mice were infected shortly after birth or at weaning and were reinfected 5 wk later, followed by assessment of airway function, airway inflammation, and lung histopathology. Infection of mice at weaning elicited a protective airway response upon reinfection. In this age group, reinfection resulted in increased airway inflammation, but without development of airway hyperresponsiveness (AHR) or eosinophilia and decreased IL-13 levels. By contrast, neonatal infection failed to protect the airways and resulted in enhanced AHR after reinfection. This secondary response was associated with the development of airway eosinophilia, increased IL-13 levels, and mucus hyperproduction. Both CD4- and CD8-positive T cells were a source of IL-13 in the lung, and inhibition of IL-13 abolished AHR and mucus production in these mice. Inoculation of UV-inactivated virus failed to elicit these divergent responses to reinfection, emphasizing the requirement for active lung infection during initial exposure. Thus, neonatal RSV infection predisposes to the development of airway eosinophilia and enhanced AHR via an IL-13-dependent mechanism during reinfection, whereas infection at a later age protects against the development of these altered airway responses after reinfection.

    Rationale: Leukotriene B-4 (LTB4) is a rapidly synthesized, early leukocyte chemoattractant that signals via its cell surface receptor, leukotriene B4 receptor 1 (BLT1), to attract and activate leukocytes during inflammation. A role for the LTB4-BLT1 pathway in allergen-induced airway hyperresponsiveness and inflammation is not well defined. Objectives: To define the role of the LTB4 receptor (BLT1) in the development of airway inflammation and altered airway function. Methods: BLT1-deficient (BLT1(-/-)) mice and wild-type mice were sensitized to ovalbumin by intraperitoneal injection and then challenged with ovalbumin via the airways. Airway responsiveness to inhaled methacholine, bronchoalveolar lavage fluid cell composition and cytokine levels, and lung inflammation and goblet cell hyperplasia were assessed. Results: Compared with wild-type mice, BLT1(-/-) mice developed significantly lower airway responsiveness to inhaled methacholine, lower goblet cell hyperplasia in the airways, and decreased interleukin (IL)-13 production both in vivo, in the bronchoalveolar lavage fluid, and in vitro, after antigen stimulation of lung cells in culture. Intracellular cytokine staining of lung cells revealed that bronchoalveolar lavage IL-1 3 levels and numbers of IL-13(+)/CD4(+) and IL-13(+)/CD8(+) T cells were also reduced in BLT1 (-/-) mice. Reconstitution of sensitized and challenged BLT1(-/-) mice with allergen-sensitized BLT1(+/+) T cells fully restored the development of airway hyperresponsiveness. In contrast, transfer of naive T cells failed to do so. Conclusion: These data suggest that BLT1 expression on primed T cells is required for the full development of airway hyperresponsiveness, which appears to be associated with IL-13 production in these cells.

    CD4+ T cells have been shown to play a role in the development of airway hyperresponsivness (AHR) and airway eosinophilia in mice using ablation as well as adoptive transfer experiments. However, as other T cell subsets (CD8, NKT) may play a role in these models, we examined the responses of sensitized CD4-deficient mice after either primary or secondary airway allergen challenge. After sensitization, CD4-deficiency in mice was not associated with airway eosinophilia, allergen-specific IgE, or elevated levels of interleukin (IL)-4 or IL-13. Increases in lung CD8 T cells and IL-5 were observed and shown to be essential for AHR as demonstrated after CD8 T cell depletion or anti-IL-5 treatment. In contrast to the response of sensitized CD4-deficient mice to primary allergen challenge, they failed to develop AHR after secondary allergen challenge. Although the importance of this CD4+ T cell-independent pathway in normal mice is unclear at this time, these studies identify the diversity of the cellular pathway, which may contribute to the development of AHR after primary allergen exposure of sensitized mice.

    Recent studies in both human and rodents have indicated that in addition to CD4(+) T cells, CD8(+) T cells play an important role in allergic inflammation. We previously demonstrated that allergen-sensitized and -challenged CD8-deficient (CD8(-/-)) mice develop significantly lower airway hyperresponsiveness (AHR), eosinophilic inflammation, and IL-13 levels in bronchoalveolar lavage fluid compared with wild-type mice, and that all these responses were restored by adoptive transfer of in vivo-primed CD8(+) T cells or in vitro-generated effector CD8(+) T cells (T-EFF). Recently, leukotriene B4 and its high affinity receptor, BLT1, have been shown to mediate in vitro-generated T-EEF recruitment into inflamed tissues. In this study we investigated whether BLT1 is essential for the development of CD8(+) T cell-mediated allergic AHR and inflammation. Adoptive trans fer of in vivo-primed BLT1(+/+), but not BLTI-/-, CD8(+) T cells into sensitized and challenged CD8(-/-) mice restored AHR, eosinophilic inflammation, and IL-13 levels. Moreover, when adoptively transferred into sensitized CD8(-/-) mice, in vitro-generated BLTI+/+, but not BLT1(-/-), T-EFF accumulated in the lung and mediated these altered airway responses to allergen challenge. These data are the first to show both a functional and an essential role for BLT1 in allergen-mediated CD8(+) T-EFF recruitment into the lung and development of AHR and airway inflammation.

    The mechanisms by which respiratory syncytial virus (RSV) infection causes airway hyperresponsiveness (AHR) are not fully established. We hypothesized that RSV infection may alter the expression of airway sensory neuropeptides, thereby contributing to the development of altered airway function. BALB/c mice were infected with RSV followed by assessment of airway function, inflammation, and sensory neuropeptide expression. After RSV infection, mice developed significant airway inflammation associated with increased airway resistance to inhaled methacholine and increased tracheal smooth muscle responsiveness to electrical field stimulation. In these animals, substance P expression was markedly increased, whereas calcitonin gene-related peptide ( CGRP) expression was decreased in airway tissue. Prophylactic treatment with Sendide, a highly selective antagonist of the neurokinin-1 receptor, or CGRP, but not the CGRP antagonist CGRP( 8 - 37), inhibited the development of airway inflammation and AHR in RSV-infected animals. Therapeutic treatment with CGRP, but not CGRP( 8 - 37) or Sendide, abolished AHR in RSV-infected animals despite increased substance P levels and previously established airway inflammation. These data suggest that RSV-induced airway dysfunction is, at least in part, due to an imbalance in sensory neuropeptide expression in the airways. Restoration of this balance may be beneficial for the treatment of RSV-mediated airway dysfunction.

    Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis during infancy and is associated with subsequent wheezing and asthma, but the nature of this association is not fully understood. We investigated the role of RSV-specific IgE antibodies in the pathophysiology of virus-induced airway dysfunction in a mouse model. Lung infection with RSV resulted in significant increases in mRNA expression for IgE and both of its high- and low-affinity receptors. In serum, virus-specific IgE antibodies reached peak levels by Day 21 after infection. Data from in vitro experiments show that RSV can induce mast cell degranulation, but only if these cells are sensitized with specific IgE. When passively sensitized in vivo with virus-specific IgE, mice developed exaggerated airway responsiveness to methacholine on airway infection, an effect that required the high-affinity receptor of IgE. These data suggest that RSV-specific IgE may contribute to the pathophysiology of airway dysfunction in children who develop this class of specific antibody.

    Allergic asthma is a complex syndrome characterized by airway obstruction, airway inflammation and airway hyperresponsiveness (AHR). Using a mouse model of allergen-induced AHR, we previously demonstrated that CD8-deficient mice develop significantly lower AHR, eosinophilic inflammation and interleukin (IL)-13 levels in bronchoalveolar lavage fluid compared with wild-type mice. These responses were restored by adoptive transfer of antigen-primed CD8(+) T cells(1). Previously, two distinct populations of antigen-experienced CD8(+) T cells, termed effector (T-EFF) and central memory (T-CM) cells, have been described(2-5). After adoptive transfer into CD8-deficient mice, T-EFF, but not T-CM, cells restored AHR, eosinophilic inflammation and IL-13 levels. T-EFF, but not T-CM, cells accumulated in the lungs, and intracellular cytokine staining showed that the transferred T-EFF cells were a source of IL-13. These data suggest an important role for effector CD8(+) T cells in the development of AHR and airway inflammation, which may be associated with their Tc2-type cytokine production and their capacity to migrate into the lung.

    The role of an interleukin (IL)-1 receptor antagonist (IL-1Ra) on the development of airway hyperresponsiveness (AHR) and airway inflammation following acute O-3 exposure in mice was investigated. Exposure of C57/BL6 mice to O-3 at a concentration of 2.0 ppm or filtered air for 3 h resulted in increases in airway responsiveness to inhaled methacholine (MCh) 8 and 16 h after the exposure, and an increase in neutrophils in the bronchoalveolar lavage (BAL) fluid. IL-1beta expression, assessed by gene microarray, was increased 2-fold 4 h after O-3 exposure, and returned to baseline levels by 24 h. Levels of IL-1beta in lung homogenates were also increased 8 h after O-3 exposure. Administration of (human) IL-1Ra before, and after O-3 exposure prevented development of AHR and decreased BAL fluid neutrophilia. Increases in chemokine levels in lung homogenates, tumor necrosis factor-alpha, MIP-2, and keratinocyte chemoattractant following O-3 exposure were prevented by IL-1Ra. Inhalation of dexamethasone, an inhibitor of IL-1 production, blocked the development of AHR, BAL fluid neutrophilia, and decreased levels of IL-1 following O-3 exposure. In summary, acute exposure to O-3 induces AHR, neutrophilic inflammation, epithelial damage, and IL-1. An IL-1Ra effectively prevents the development of altered airway function, inflammation, and structural damage.

    In certain models of allergic airway disease, mast cells facilitate the development of inflammation and airway hyper-responsiveness (AHR). To define the role of the high affinity IgE receptor (Fcis an element ofRI) in the development of AHR, mice with a disruption of the a subunit of the high affinity IgE receptor (Fcis an element ofRI(-/-)) were exposed on 10 consecutive days to nebulized OVA. Forty-eight hours after the last nebulization, airway responsiveness was monitored by the contractile response of tracheal smooth muscle to electrical field. stimulation (EFS). After the 10-day OVA challenge protocol, wild-type mice demonstrated increased responsiveness to EFS, whereas similarly challenged Fcis an element ofRI(-/-) mice showed a low response to EFS, similar to nonexposed animals. Further, allergen-challenged Fcis an element ofRI(-/-) mice showed less airway inflammation, goblet cell hyperplasia, and lower levels of IL-13 in lung homogenates compared with the controls. IL-13-deficient mice failed to develop an increased response to EFS or goblet cell hyperplasia after the 10-day OVA challenge. We transferred bone marrow-derived mast cells from wild-type mice to Fcis an element ofRI(-/-) mice 1 day before initiating the challenge protocol. After the 10-day OVA challenge, recipient Fcis an element ofRI(-/-) mice demonstrated EFS-induced responses similar to those of challenged wild-type mice. Transferred mast cells could be detected in tracheal preparations. These results show that Fcis an element ofRI is important for the development of AHR after an aerosolized allergen sensitization protocol and that this effect is mediated through Fcis an element ofRI on mast cells and production of IL-13 in the lung.

    The role of Th2/CD4 T cells, which secrete IL-4, IL-5, and IL-13, in allergic disease is well established; however, the role of CD8(+) T cells (allergen-induced airway hyperresponsiveness (AHR) and inflammation) is less clear. This study was conducted to define the role of Ag-primed CD8(+) T cells in the development of these allergen-induced responses. CD8-deficient (CD8(-/-)) mice and wild-type mice were sensitized to OVA by i.p. injection and then challenged with OVA via the airways. Compared with wild-type. mice, CD8(-/-) mice developed significantly lower airway responsiveness to inhaled methacholine and lung eosinophilia, and exhibited decreased IL-13 production both in vivo, in the bronchoalveolar lavage (BAL) fluid, and in vitro, following Ag stimulation of peribronchial lymph node (PBLN) cells in culture. Reconstitution of sensitized and challenged CD8(-/-) mice with allergen-sensitized CD8(+) T cells fully restored the development of AHR, BAL cosinophilia, and IL-13 levels in BAL and in culture supernatants from PBLN cells. In contrast, transfer of naive CD8(+) T cells or allergen-sensitized CD8(+) T cells from IL-13-deficient donor mice failed to do so. Intracellular cytokine staining of lung as well as PBLN T cells revealed that CD8(+) T cells were a source of IL-13. These data suggest that Ag-primed CD8(+) T cells are required for the full development of AHR and airway inflammation, which appears to be associated with IL-13 production from these primed T cells.

    Background: IL-13 is a central mediator of allergen-induced airway hyperresponsiveness, (AHR), but its role in respiratory syncytial virus (RSV)-induced AHR is not defined. The combination of allergen exposure and RSV infection is known to increase AHR and lung inflammation, but whether IL-13 regulates this increase is similarly not known.
    Objective: Our objective was to determine the role of RSV infection and IL-13 on airway responsiveness and lung inflammation on sensitized and challenged mice.
    Methods: Using a murine model of RSV infection and allergen exposure, we examined the role of IL-13 in the development of AHR and lung inflammation in IL-13 knockout mice, as well as using a potent IL-13 inhibitor (IL-13i). Mice were sensitized and challenged to allergen, and 6 days after the last challenge, they were infected with RSV. IL-13 was inhibited using an IL-13 receptor alpha(2)-human IgG fusion protein. AHR to inhaled methacholine was measured 6 days after infection, as was bronchoalveolar lavage fluid and lung inflammatory and cytokine responses.
    Results: RSV-induced AHR was unaffected by the IL-13i, despite prevention of goblet cell hyperplasia. Similar results were seen in IL-13-deficient mice. In sensitized and challenged mice, RSV infection significantly increased AHR, and after IL-13i treatment, AHR was significantly reduced, but to the levels seen in RSV-infected mice alone.
    Conclusions: These results indicate that despite some similarities, the mechanisms leading to AHR induced by RSV are different from those that follow allergen sensitization and challenge. Because IL-13 inhibition is effective in preventing the increases in AHR and mucus production in sensitized and challenged mice infected with RSV, IL-13i could play an important role in preventing the consequences of viral infection in patients with allergic asthma.

    The lung collectin surfactant protein D (SP-D) is an important component of the innate immune response but is also believed to play a role in other regulatory aspects of immune and inflammatory responses within the lung. The role of SP-D in the development of allergen-induced airway inflammation and hyperresponsiveness (AHR) is not well defined. SP-D levels progressively increased up to 48 hours after allergen challenge of sensitized mice and then subsequently decreased. The levels of SP-D paralleled the development of airway eosinophilia and AHR. To determine if this association was functionally relevant, mice were administered rat SP-D (rSP-D) intratracheally. When given to sensitized mice before challenge, AHR and eosinophilia were reduced by rSP-D in a dose-dependent manner but not by mutant rSP-D. rSP-D administration resulted in increased levels of interleukin (IL)-10, IL-12, and IFN-gamma in bronchoalveolar lavage fluid and reduced goblet cell hyperplasia. Culture of alveolar macrophages together with SP-D and allergen resulted in increased production of IL-10, IL-12, and IFN-gamma. These results indicate that SP-D can (negatively) regulate the development of AHR and airway inflammation after airway challenge of sensitized mice, at least in part, by modulating the function of alveolar macrophages.

    An 81 year old man was admitted to hospital with pulmonary Mycobocterium tuberculosis infection and was treated with rifampicin (UP), isoniazid (INH), and ethambutol (EB). On day 9 he developed fever and dyspnoea. Chest radiographs showed new infiltration shadows in the right lung. Bronchoalveolar lavage (BAL) was performed and increased numbers of lymphocytes were recovered. Drug induced pneumonitis was suspected so the antituberculous regimen was discontinued and methylprednisolone was administered. The symptoms and infiltration shadows improved. INH and EB were reintroduced without any recurrence of the abnormal shadows. T cell subsets in the BAL fluid and a positive lymphocyte stimulation test for RFP suggest that RFP induced pneumonitis may be related to a complex immunological response.

    Patients with chronic obstructive pulmonary disease (COPD) are difficult to assess by conventional transthoracic echocardiography (TTE) because of emphysematous lungs or mediastinal deviation. We hypothesized that superior vena cava (SVC) flow is related to pulmonary circulation and may be useful for the detection of pulmonary hypertension (PH) in patients with COPD that cannot been assessed by direct evaluation using the tricuspid regurgitant Doppler velocity. SVC Doppler flow velocities were examined in 46 patients with COPD and the pressure gradient between the right ventricular and right atrial. pressure (RV-RADeltaP) was calculated by tricuspid regurgitant Doppler velocities. The patients were divided into 2 groups: 11 patients with PH (RV-RADeltaP &gt; 25 min Hg) were compared with 35 without PH. There was no significant difference in the maximal SVC peak systolic forward flow velocity during inspiration (INS) between these 2 groups. However, the minimal SVC peak systolic forward flow velocity during expiration (EXP) in the group with PH was significantly higher than that in the group without PH (37.4 +/- 20.0 cm/s vs 26.4 +/- 8.5 cm/s, P = .01). Linear regression analysis revealed a significant correlation between RV-RADeltaP and the EXP/INS ratio (r = 0.61, P &lt; .001). in COPD patients with PH, the increased expiratory SVC systolic flow supplemented the preload for the impaired right ventricular filling flow caused by PH, thereby maintaining the transtricuspid driving pressure. Our observation suggests that respiratory variation in SVC systolic forward flow may be a sensitive Doppler flow index for evaluating severity of PH in patients with COPD that cannot been assessed by conventional TTE.

Physical examination revealed a hard, rounded, a little bigger than egg-sized mass in the right scrotum. The second case was a 40-year-old man who was admitted to our hospital because of cough, fever and body weight loss. He was treated for pulmonary tuberculosis with isoniazid, rifampicin, streptomycin and pyrazinamide. Six months after admission, he complained of a painless swelling of the right scrotum. Physical examination revealed a hard, rounded, more than egg-sized mass in the right scrotum. Right orchiectomy was performed in these two cases, and they were cured.

    A 27-year-old man with a primary pulmonary lymphoma of large B-cell type is described. Symptoms involved both the upper and lower respiratory tract. A chest roentgenogram showed a dense mass with cavitation. Transbronchial biopsy specimens revealed no atypical cells, rather they demonstrated granulomatous infiltration and vasculitis consistent with but not conclusively diagnostic of Wegener's granulomatosis. The pulmonary mass became smaller after sulfamethoxazole-trimethoprim therapy. These features suggested Wegener's granulomatosis. However, an open biopsy specimen was diagnostic for diffuse lymphoma of large B-cell type. High-grade pulmonary lymphoma should be considered in the differential diagnosis of patients with clinical and pathologic features suggesting Wegener's granulomatosis.

    Alpha-1-antitrypsin (alpha1AT) deficiency is extremely rare among Orientals. We treated a 37-year-old man with severe pulmonary emphysema associated with a low serum concentration of alpha1AT. Mutation analysis of the alpha1AT gene was performed using a reverse transcription-polymerase chain reaction followed by sequencing. The patient proved to be a compound heterozygote carrying a S(iiyama) deficient allele and a QO(clayton) null allele. This is the first Japanese case of alpha1AT deficiency to arise from such compound heterozygosity in a family with no apparent consanguineous marriage, suggesting that the gene frequency for deficient alleles might be somewhat higher than previously estimated.

    Although the rehabilitation of patients with chronic obstructive pulmonary disease (COPD) improves both exercise capacity and quality of life, a standard protocol for COPD patients has not been established. To clarify whether physiologic and quality-of-life improvements can be achieved by an inpatient pulmonary rehabilitation program 5 days per week for 3 weeks, 18 patients with COPD were enrolled in a rehabilitation program. The physical exercise training regimen consisted of respiratory muscle stretch gymnastics and cycle ergometer exercise training. Pulmonary function tests, an incremental ergometer exercise test, a 6-min walking test, and a quality of life assessment by the Chronic Respiratory Questionnaire were administered before and after the program. The peak VO2, an indicator of maximal exercise capacity, did not increase, although the 6-min walking distance, an indicator of functional exercise capacity, increased significantly after rehabilitation. There was a significant improvement in the quality of life in terms of dyspnea, fatigue, and emotional state. These findings suggest that even a 3-week program may be beneficial for COPD patients. Increases in functional exercise capacity, even without an increase in maximal exercise capacity, are helpful for reducing dyspnea and improving quality of life parameters in patients with COPD.

    OBJECTIVE: The ramp exercise test has been widely used to evaluate cardiopulmonary responses to an incremental exercise load. This study was performed to clarify whether different slopes of the ramp exercise test influence exercise tolerance, exercise limiting factors, and respiratory pattern in patients with chronic obstructive pulmonary disease (COPD). SUBJECTS AND METHODS: We applied three different slopes (5 W/min, 10 W/min and 20 W/min) of the ramp exercise test in 9 patients with COPD and evaluated cardiopulmonary responses. RESULTS: There were no significant differences in peak oxygen uptake, anaerobic threshold (AT), minute ventilation, heart rate, arterial oxygen saturation, expired tidal volume, or respiratory rate at the maximal load among the three different ramp exercises tested. AT could be determined in six of nine patients (67%) at the slope of 5 W/min, in 8/9 (89%) at the slope of 10 W/min, and in 9/9 (100%) at the slope of 20 W/min. CONCLUSION: The findings suggest that the ramp slope does not affect exercise tolerance, exercise limiting factors, or respiratory patterns and each of these ramp slopes is useful for the evaluation of COPD. Ramp slopes of 10 W/ min or 20 W/min should be appropriate for the determination of AT.

    We report the transient spontaneous disappearance of a mucocele due to bronchial atresia. Two years before presentation, a chest radiograph showed a hyperlucent right upper lung and a mucocele near the right hilum. A chest radiograph taken 1 year later showed that the mucocele had disappeared leaving an ovoid outline of a dilated bronchus. A chest radiograph obtained 3 months before presentation showed that the mucocele was present again. Atresia of the B3b bronchus of the right upper lobe was noted on thoracotomy. The "disappearance" of the mucocele probably was due to the clearance of mucoid material through collateral airways.

    慢性閉塞性肺疾患(COPD)は進行性の肺および気道の炎症および破壊を生じる疾患であり、肺や気道の変化は不可逆的であり、現在のところ治療としては気管支拡張剤等による対症療法しかない。間葉系幹細胞(MSC)は、血管内皮細胞や神経細胞などの間葉系に属する細胞への分化能を有し、2型肺胞上皮への分化能も有する。炎症抑制作用も有しており、急性、慢性炎症性疾患での治療効果が報告されているが、COPDの臨床試験では炎症反応や肺機能の有意な改善効果が認められず、抗炎症作用、組織修復作用のより優れたMSCの開発が必須である。
    CCL2はマクロファージやリンパ球の遊走に関わる炎症性ケモカインであり、COPDの気道炎症、破壊に深く関与している。CCL2のドミナントネガティブ阻害剤導入MSC(7ND-MSC)は強力なCCL2抑制効果を有しており、マクロファージ等の抑制による抗炎症効果が通常のMSCより優れていると考えられる。本研究では7ND-MSCの肺気腫治療効果を通常のMSCと比較検討し、7ND-MSCの肺気腫治療への有用性を明らかにすることを目的とする。
    まず、マウスにエラスターゼを経気道投与し、肺気腫を誘導したところ、気管支肺胞洗浄液中のCCL2の有意な上昇を認め、気腫誘導へのCCL2の関与が示唆された。次にマウスエラスターゼ誘導肺気腫モデルマウスに7ND-MSCを投与したところ、通常のMSCに比較し、有意に肺気腫の進展抑制効果を得ることができた。また、7ND-MSC投与により、通常MSC投与に比較し、より強力なマクロファージ、リンパ球、好中球などの炎症細胞の増加抑制が得られており、炎症と気腫改善のより優れた改善効果を得た。
