A 35-year-old female presented with headache, photophobia and developed sudden loss of vision after having undergone right-side ophthalmectomy and radiochemotherapy for retinoblastoma in infancy. A neoplastic lesion was found in the left middle cranial fossa and was surgically removed. The diagnosis was radiation-induced osteosarcoma with RB1 gene alteration. Although she received chemotherapy for the residual tumor, it progressed 17 months later. Maximal surgical resection with craniofacial reconstruction was required. We utilized two three-dimensional models for surgical planning. She was discharged without neurological deficits other than loss of light perception subsequent to left ophthalmectomy. In cases where retinoblastoma is treated with radiotherapy, long-term follow-up is necessary to monitor for radiation-induced tumor development.

A 44-year-old Japanese man presented with fever and sore throat. He had a history of refractory chronic sinusitis that did not respond to several years of pharmacotherapy, and underwent endoscopic sinus surgery (ESS) 5 months prior to his presentation, but his symptoms persisted. A biopsy specimen was taken from the right nasal cavity, and extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) was diagnosed. Two years after complete remission was achieved by chemoradiation therapy, he developed hemophagocytic lymphohistiocytosis (HLH) without recurrence of ENKTL. Epstein-Barr virus (EBV)-DNA copy number was relatively high and EBV-infected lymphocytes (CD8 + T cells) were detected in the peripheral blood. Pathological review of the biopsy specimens taken during ESS showed that CD8 + T cells with slightly atypia infiltrating the stroma were EBV positive. These findings suggested that the patient had underlying chronic active EBV infection (CAEBV) that caused the refractory chronic sinusitis, eventually developed into ENKTL, and also caused HLH. Clinicians should consider adult-onset CAEBV in the differential diagnosis of patients with refractory chronic sinusitis.

OBJECTIVE: Combination intranasal drugs with a corticosteroid and antihistamine are available in several countries with better effect than treatments with single agents. However, it remains unclear whether this effect is also seen in Japanese cedar pollinosis (JCP), the most prevalent seasonal allergic rhinitis in Japan. We investigated the effect of an add-on intranasal antihistamine with an intranasal corticosteroid in JCP during the pollen dispersal period. (UMIN000025508) METHODS: We performed a double-blinded, randomized, placebo-controlled trial from March 1 to 14, 2017. Patients (n = 20 per group) received either a mometasone furoate nasal spray (MFNS) plus a levocabastine nasal spray (levocabastine group) or MFNS plus a placebo nasal spray (placebo group). The primary endpoint was the difference in the total nasal symptom score (TNSS) after treatment between the two groups. Differences in the total ocular symptom score, total symptom score, total medication score, total symptom-medication score, and five individual symptoms as well as safety were the secondary endpoints. RESULTS: The change in the TNSS from baseline was significantly greater in the levocabastine group than in the placebo group. A significant reduction in the TNSS was observed more than 6 days earlier in the levocabastine group than in the placebo group. Such add-on effects were also seen in the secondary endpoints. Both treatments were well-tolerated. CONCLUSION: The intranasal antihistamine provided better control of not only nasal symptoms, but also of ocular symptoms, and decreased the need for rescue medications when added to intranasal corticosteroid treatment in JCP patients.

BACKGROUND: The total naso-ocular symptom score (TSS) is widely used as an endpoint to evaluate the severity of seasonal allergic rhinitis. However, it is not a generic preference-based measure. We sought to develop an algorithm for mapping between the TSS and health utility in Japanese cedar pollinosis (JCP). We also performed a cost-utility analysis of sublingual immunotherapy (SLIT) for JCP by using this algorithm. METHODS: Patients with JCP filled out the TSS questionnaire and EQ-5D-5L simultaneously during the pollen season in 2019 and in 2020. We estimated a direct utility mapping model by regressing responses to individual TSS questions directly onto utility. The incremental cost-effectiveness ratio (ICER) of active SLIT to a placebo was determined by examining the drug expense and the estimated quality-adjusted life year (QALY) using a dataset from a double-blind placebo-controlled clinical trial. RESULTS: A total of 238 records were included for analysis. The estimated utility decreased with increasing severity of rhinitis. Patients with comorbid asthma showed lower utility. A negative and significant correlation was seen between the TSS and utility in both 2019 and 2020. The estimated equations were: Y(utility) = -0.0161∗X(TSS) + 1.005 in non-asthmatic JCP patients. The ICER of active SLIT to the placebo was estimated to be 4,049,720 and 6,011,218 JPY/QALY in the first and second year, respectively. CONCLUSIONS: It is possible to reasonably predict utility from the total naso-ocular symptom score by using regression models. In the estimated algorithm, pre-seasonal SLIT for JCP is cost-effective.

BACKGROUND: Strong eosinophil infiltration in chronic rhinosinusitis with nasal polyp (CRSwNP) is highly associated with recalcitrance and higher nasal polyp recurrence rate after surgery. The prevalence of eosinophilic CRSwNP (ECRS) is increasing in Asian countries including Japan. Benralizumab is a humanized anti-IL-5R alpha monoclonal antibody that depletes eosinophils by antibody-dependent cell-mediated cytotoxicity. OBJECTIVE: To assess the efficacy and safety of benralizumab in patients with ECRS. METHODS: This phase II, randomized, double-blind, placebo-controlled study was conducted in Japan. Patients were randomized 1:2:2 to placebo, a single administration of benralizumab 30 mg, or benralizumab 30 mg every 4 weeks (q4w) for a total of three doses. The primary endpoint was the change in nasal polyp score from baseline at Week 12. RESULTS: Overall, 56 patients were enrolled (placebo, n = 11; benralizumab single dose, n = 22; benralizumab q4w, n = 23). Although the mean total nasal polyp score began to decrease after the initiation of benralizumab treatment, there were no statistically significant differences in change in nasal polyp score from baseline at Week 12 between benralizumab and placebo (placebo, -0.5 ± 0.8; benralizumab single, -0.3 ± 0.8; benralizumab q4w, -0.5 ± 1.5). Post-hoc analysis showed that the administration of benralizumab decreased nasal polyp scores ≥2 points in 42.2% of ECRS patients and that patients with high blood eosinophil levels had a greater tendency to respond to benralizumab treatment. The safety profile was similar to that in previous studies and no unexpected adverse events were noted. CONCLUSION: Although benralizumab did not meet the primary efficacy endpoint, reductions of nasal polyp scores were seen in the benralizumab group compared with the placebo group over the whole study period, especially in patients with high levels of blood eosinophils.

BACKGROUND: Hyaluronan is one of the major extracellular matrixes in chronic rhinosinusitis (CRS) associated with tissue remodeling. Prostaglandin D2 (PGD2) is also associated with the pathogenesis of CRS. However, little is known about whether PGD2 regulates hyaluronan production by human airway fibroblasts. OBJECTIVE: We sought to determine the effect of PGD2 on the mRNA expression of three isoforms of membrane-bound hyaluronic acid synthase (HAS1, HAS2 and HAS3) in fibroblasts, the major source of hyaluronan production, derived from CRS patients. METHODS: Nasal polyp-derived fibroblasts (NPDF) and uncinate tissue-derived fibroblasts (UTDF) were established from CRS patients with nasal polyps and those without, respectively. These fibroblasts were stimulated with PGD2 or PGD2 receptor (DP/CRTH2)-selective agonists in the presence or absence of receptor-selective antagonists. mRNA levels for HAS1, HAS2 and HAS3 were determined by real-time quantitative PCR. RESULTS: PGD2 (1 µM) significantly enhanced HAS1 but not HAS2 or HAS3 mRNA expression by NPDF. Enhanced HAS1 mRNA expression was also obtained by stimulation with a DP receptor-selective agonist, but not with a CRTH2 receptor-selective agonist. In addition, PGD2-induced HAS1 mRNA expression was significantly inhibited by pre-treatment with DP receptor-selective antagonists. Similar induction of PGD2-induced HAS1 mRNA expression was seen in UTDF. CONCLUSION: PGD2 selectively stimulates HAS1 mRNA expression in local fibroblasts in CRS via DP, but not CRTH2, receptors.

BACKGROUND: Type 2 chronic rhinosinusitis (CRS), especially eosinophilic CRS (ECRS), is an intractable upper airway inflammatory disease. Establishment of serum biomarkers reflecting the pathophysiology of CRS is desirable in a clinical setting. As IgG4 production is regulated by type 2 cytokines, we sought to determine whether serum IgG4 levels can be used as a biomarker for CRS. METHODS: Association between the serum IgG4 levels and clinicopathological factors was analyzed in 336 CRS patients. Receiver operating characteristics (ROC) analysis was performed to determine the cut-off value of serum IgG4 levels that can be used to predict the post-operative recurrence. RESULTS: Serum IgG4 levels were significantly higher in patients with moderate to severe ECRS versus those with non to mild ECRS. The levels were also significantly higher in asthmatic patients and patients exhibiting recurrence after surgery compared to controls. ROC analysis determined that the best cut-off value for the serum IgG4 level to predict the post-operative recurrence was 95 mg/dL. The corresponding sensitivity and specificity were 39.7% and 80.5%, respectively. When we combined the two cut-off values for the serum IgG4 and periostin, patients with high serum levels of either IgG4 or periostin exhibited a high post-operative recurrence (OR: 3.95) as compared to patients having low serum levels of both IgG4 and periostin. CONCLUSIONS: The present results demonstrate that the serum IgG4 level is associated with disease severity and post-operative course in CRS. In particular, the combination of serum IgG4 and periostin could be a novel biomarker that predicts post-operative recurrence.

HYPOTHESIS: Macrophage migration inhibitory factor plays an important role in the expression of interleukin (IL)-1β and the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome in lipopolysaccharide-induced otitis media. BACKGROUND: NLRP3 inflammasome and macrophage migration inhibitory factor are critical molecules mediating inflammation. However, the interaction between the NLRP3 inflammasome and macrophage migration inhibitory factor has not been fully examined. METHODS: Wild-type mice and macrophage migration inhibitory factor gene-deficient (MIF) mice received a transtympanic injection of either lipopolysaccharide or phosphate-buffered saline. The mice were sacrificed 24 hours after the injection. Concentrations of IL-1β, NLRP3, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain and a pyrin domain), and caspase-1 in the middle ear effusions were measured by enzyme-linked immunosorbent assay. Temporal bones were processed for histologic examination and immunohistochemistry. RESULTS: In the immunohistochemical study using the wild-type mice, positive staining of macrophage migration inhibitory factor, NLRP3, ASC, and caspase-1 were observed in infiltrating inflammatory cells induced by lipopolysaccharide in the middle ear. The number of inflammatory cells caused by lipopolysaccharide administration decreased remarkably in the MIF mice as compared with the wild-type mice. The concentrations of IL-1β, NLRP3, ASC, and caspase-1 increased in the lipopolysaccharide-treated wild-type mice. The MIF mice with lipopolysaccharide had decreased levels of IL-1β, NLRP3, ASC, and caspase-1 as compared with the wild-type mice. CONCLUSION: Macrophage migration inhibitory factor has an important role in the production of IL-1β and the NLRP3 inflammasome. Controlling the inflammation by modulating macrophage migration inhibitory factor and the NLRP3 inflammasome may be a novel therapeutic strategy for otitis media.

BACKGROUND: A remarkable relationship between upper airway conditions and lung diseases has been reported. At the same time, sinonasal findings in chronic cough patients have not been fully examined. OBJECTIVE: The purpose of this study is to show paranasal sinus findings and lung function in chronic cough patients without asthma and chest X-ray abnormalities. METHODS: A total of 1412 patients with persistent cough were enrolled in this study. Of these patients, 376 patients were evaluated for further examination, as the patients with asthma and/or chest X-ray abnormality were excluded from the study. Normal control subjects without any chronic respiratory symptoms were also recruited. Pulmonary function was examined by spirometry. A bronchial obstruction reversibility test was applied. The Lund-Mackay computed tomography (CT) score, peripheral blood eosinophil count, and immunoglobulin E concentration in serum samples were examined. The Sino-Nasal Outcome Test was used to determine the severity of clinical symptoms. RESULTS: The patients with an abnormal soft tissue shadow in the paranasal sinus had significant obstructive lung function. The percent predicted forced expiratory volume in 1 second (FEV1.0) and the FEV1.0/forced vital capacity ratio negatively correlated with Lund-Mackay CT scores both before and after bronchodilator inhalation. There was a statistically significant correlation between pulmonary function and eosinophil count. CONCLUSION: The patients with chronic cough frequently had paranasal sinus abnormalities. The Lund-Mackay CT score may be useful for assessing the condition of the lower airway in chronic cough patients. Upper airway examinations should play a part in the management of chronic cough.

BACKGROUND: IgG4 production is regulated by type 2 (IL-4 and IL-13) and regulatory (IL-10) cytokines involved in the pathophysiology of chronic rhinosinusitis (CRS). We sought to determine the pathophysiological characteristics of IgG4-positive cells in sinonasal tissues in CRS, especially eosinophilic CRS (ECRS). METHODS: IgG4-positive cells in uncinate tissues (UT) and nasal polyps (NP) were examined by immunohistochemistry. Associations between the number of IgG4-positive cells and clinicopathological factors were analyzed. Receiver operating characteristics (ROC) analysis was performed to determine the cut-off value of IgG4-positive cells in tissue that can predict the post-operative course. RESULTS: IgG4 was mainly expressed in infiltrating plasma and plasmacytoid cells, and the number of IgG4-positive cells was significantly higher in NP, especially those from severe ECRS patients, than in UT. In CRS patients, the number of IgG4-positive cells significantly and positively correlated with blood and tissue eosinophilia, radiological severity, and serum level of total IgE. The number of infiltrating IgG4-positive cells was significantly higher in patients with a poor post-operative course (sustained sinus shadow 6 months after surgery) than in those with a good one. The number of IgG4-positive cells in NP could discriminate patients with a good or a poor post-operative course (area under the curve: 0.769). Also, 73.3% sensitivity and 82.5% specificity were achieved when the cut-off value was set at 17 cells/high-power field. CONCLUSIONS: Our results suggest that the local expression of IgG4 on cells may be used as a biomarker that reflects the pathophysiology of CRS, including the post-operative course.

: Prophylactic treatment with intranasal corticosteroids is effective for pollen-induced seasonal allergic rhinitis. However, the appropriate time to start this treatment remains unclear. We performed a double-blinded, randomized, placebo-controlled trial. Starting on February 1, 2014, patients with Japanese cedar pollinosis received either fluticasone furoate nasal spray (FFNS) for 8 weeks (Group A: n = 24), placebo nasal spray for 2 weeks followed by FFNS for 6 weeks (Group B: n = 23), or placebo for 4 weeks followed by FFNS for 4 weeks (Group C: n = 23). The primary endpoint was comparison of the total naso-ocular symptom score (TSS). Secondary endpoints including the increment cost effective ratio (ICER) were also determined. Continuous pollen dispersion began on the 24th of February. Therefore, Group A and Group B received 3-weeks and 1-week of prophylactic treatment, respectively, whereas Group C received post-onset treatment. During the peak pollen-dispersal period, significant differences in TSS were seen between the groups, particularly between Group A and C. The ICER of Group B vs. Group C was lower than that of Group A vs. Group C. These results suggest that long-term prophylactic treatment with FFNS is clinically the most potent treatment, whereas short-term prophylactic treatment is cost effective for pollen-induced allergic rhinitis.

BACKGROUND: The development of methods to predict the clinical effectiveness of sublingual immunotherapy (SLIT) for allergic diseases is a crucial matter. We sought to determine whether whole saliva, which is the first body component that contacts allergen extracts during SLIT, is associated with the clinical effectiveness of SLIT in Japanese cedar pollinosis. METHODS: Blood monocytes or monocytic THP-1 cells were cultured in the presence or absence of either whole saliva or pure saliva with or without treatments including filtration and blockade of TLR2 and/or TLR4 signaling. IL-10 levels in the supernatants were then measured. Whole saliva-induced IL-10 production by THP-1 cells was compared between asymptomatic and disease-onset patients during peak pollen dispersal after SLIT. RESULTS: Both monocytes and THP-1 cells produced substantial amounts of IL-10 in response to whole saliva. IL-10 production was significantly reduced in response to pure saliva and 0.2 μm-filtered saliva. Simultaneous treatment with polymyxin B and TL2.1, a neutralizing antibody against TLR2, also reduced IL-10 production. IL-10 levels produced by THP-1 cells in response to whole saliva collected prior to SLIT were significantly higher in asymptomatic patients determined by symptom-medication scores than disease-onset patients following SLIT. Such differences were not seen in saliva collected 3 months after the initiation of SLIT or saliva collected during peak pollen dispersal. CONCLUSIONS: Our results provide a basis for why the sublingual route is effective and preferable in allergen immunotherapy. Saliva-induced IL-10 levels produced by THP-1 cells may be a predictive marker for clinical remission after SLIT.

BACKGROUND: The nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome is a critical molecule mediating interleukin-1β (IL-1β) responses. However, the role of the NLRP3 inflammasome in otitis media has not been fully examined. AIMS/OBJECTIVES: The purpose of this study is to assess the expression of NLRP3, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain and a pyrin domain), and caspase-1 in lipopolysaccharide-induced otitis media. MATERIALS AND METHODS: BALB/c mice received a transtympanic injection of either lipopolysaccharide or phosphate-buffered saline. The mice were sacrificed 24 h after injection. Concentrations of IL-1β, NLRP3, ASC, and caspase-1 in the middle ear effusions were measured by enzyme-linked immunosorbent assay. Temporal bones were processed for histologic examination and immunohistochemistry. RESULTS: The transtympanic injection of lipopolysaccharide significantly upregulated levels of IL-1β, NLRP3, ASC, and caspase-1 in the middle ear as compared with the control mice. The proteins of NLRP3, ASC, and caspase-1 were observed in infiltrating inflammatory cells induced by lipopolysaccharide in the middle ear cavity. CONCLUSIONS AND SIGNIFICANCE: Lipopolysaccharide induces NLRP3 inflammasome components in the middle ear. The NLRP3 inflammasome may play an important role in the pathogenesis of otitis media. Modulation of inflammasome-mediated inflammation may be a novel therapeutic strategy for otitis media.

BACKGROUND: IL-10 is a major anti-inflammatory cytokine that prevents inflammation-mediated tissue damage. We characterized the production of IL-10 by sinonasal tissue cells following exposure to Staphylococcus aureus enterotoxin B (SEB), which elicits cellular responses and is associated with the pathogenesis of eosinophilic chronic rhinosinusitis (ECRS). METHODS: Dispersed nasal polyp (NP) cells and uncinate tissue (UT) cells were prepared from patients with CRS with and without NP, respectively. Cells were incubated with SEB, and then the levels of IL-10 in the cell supernatants were determined. The effect of neutralizing IL-10 on SEB-induced IL-5, IL-13, IFN-γ, and IL-17A production was examined. Expression of IL-10 in NPs was also determined. RESULTS: IL-10 was expressed in infiltrating inflammatory cells in NPs. NP cells, especially non-adherent NP cells, produced substantial amounts of IL-10 in response to SEB. Although baseline production of IL-10 was significantly higher in NP cells than UT cells, the degree of IL-10 response to SEB was not significantly different between the cell types. The degree of IL-10 production was negatively correlated with the degree of eosinophilia both in tissues and peripheral blood whereas positively correlated with the 1-s forced expiratory volume/forced vital capacity ratio. Patients with severe ECRS displayed a significant decrease in IL-10 production compared with those with non-ECRS. IL-10 neutralization significantly augmented SEB-induced IL-13 and IFN-γ production by NP cells. CONCLUSIONS: Impaired IL-10 production in response to SEB in NP may exacerbate the pathophysiology of ECRS including eosinophilia and lower airway obstruction.

OBJECTIVE: In 2013, the Japanese Rhinologic Society proposed a simple classification for endoscopic sinus surgery (ESS). This classification consists of five procedures (type I, fenestration of the ostiomeatal complex, with uncinectomy and widening of the natural ostium; type II, single-sinus procedure, with manipulating the inside of the sinus; type III, polysinus procedure; type IV, pansinus procedure; type V, extended procedure beyond the sinus wall). The clinical relevance of this classification in chronic rhinosinusitis (CRS) and paranasal sinus cyst was evaluated. STUDY DESIGN: A retrospective validation study. METHODS: A total of 122 patients (195 sinuses) who underwent ESS in Okayama University Hospital in 2012 were enrolled. The relationships between the ESS classification and the clinical course, including the operation time, bleeding amounts during surgery and postoperative changes of olfaction, the computed tomography (CT) score, and nasal airway resistance were analyzed. RESULTS: A total of 195 ESS procedures were classified into type I (n = 3), type II (n = 17), type III (n = 91), type IV (n = 82), and type V (n = 2). The major phenotypes of type II, III, and IV ESS were paranasal sinus cyst (68%), CRS without nasal polyps (77%), and CRS with nasal polyps (55%), respectively, and the difference was significant. The degree of ESS based on this classification was positively and significantly correlated with the operation time and bleeding amounts. As a whole, olfaction, CT score, and nasal airway resistance were significantly improved after surgery. The degree of improvement was similar between type III and type IV ESS. CONCLUSION: This simple classification for ESS reflected the perioperative burden of the disease.

CONCLUSIONS: Chronic rhinosinusitis diagnosed according to the European Position Paper on Rhinosinusitis and Nasal Polyps 2012, not by computed tomography alone, is one of the prognostic factors affecting long-term survival in patients with lung transplantation. Endoscopic sinus surgery might play a beneficial role in the management of lung transplantation recipients with chronic rhinosinusitis. OBJECTIVE: To show the effect of paranasal sinus infection on post-lung transplantation survival. METHOD: Lung transplantation recipients were included in this study. Computed tomography was performed before and after lung transplantation. The severity of chronic rhinosinusitis was evaluated by Lund-Mackay scoring system. The survival rate was calculated by the Kaplan-Meier method. RESULTS: One hundred and forty-eight patients received lung transplantation for various indications. Chronic rhinosinusitis was found in 18.9% (28/148) of the lung transplantation recipients. Of 28 patients with chronic rhinosinusitis, seven patients underwent endoscopic sinus surgery due to persistent post-nasal drip. The recipients with chronic rhinosinusitis who did not receive endoscopic sinus surgery (n = 21) showed a significantly lower survival rate as compared to the patients without chronic rhinosinusitis. There was no statistically significant difference in the survival rate between the recipients with (n = 50) and without (n = 98) paranasal sinus abnormality on computed tomography.

BACKGROUND: IL-22 is an IL-10-family cytokine that regulates chronic inflammation. We investigated the role of IL-22 and its receptor, IL-22R1, in the pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS: IL-22 and IL-22R1 protein and mRNA expression in NP and in uncinate tissues (UT) from CRS and non-CRS patients was examined using immunohistochemistry and real-time PCR, respectively. Dispersed NP and UT cells were cultured with the Staphylococcus aureus exotoxins, staphylococcal enterotoxin B and alpha-toxin, following which exotoxin-induced IL-22 levels and their association with clinicopathological factors were analyzed. Effects of IL-22 on MUC1 expression and cytokine release in NP cells were also determined. RESULTS: IL-22 and IL-22R1 in NP were mainly expressed in infiltrating inflammatory cells and in epithelial cells, respectively. IL-22 mRNA levels in NP were significantly higher than those in UTs from non-CRS patients whereas IL-22R1 levels were conversely lower in NPs. NP cells produced substantial amounts of IL-22 in response to exotoxins. Exotoxin-induced IL-22 production by NP cells significantly and negatively correlated with the degree of local eosinophilia and postoperative computed tomography (CT) score, whereas conversely it positively correlated with the forced expiratory volume in 1s (FEV1)/forced vital capacity (FVC) ratio. IL-22 significantly enhanced MUC1 mRNA expression in NP cells. IL-22-induced MUC1 mRNA levels were significantly and positively correlated with IL-22R1 mRNA levels in NPs. CONCLUSIONS: These data suggest that imbalance of IL-22/IL-22R1 signaling regulates the pathogenesis of CRSwNP, including local eosinophilia, via alteration of MUC1 expression.

BACKGROUND: Minimal persistent inflammation (MPI) contributes to hyperreactivity in allergic rhinitis. However, little is known regarding whether pre-onset activation of eosinophils and mast cells is present or not in Japanese cedar pollinosis (JCP). Furthermore, a prophylactic effect of intranasal corticosteroids on such MPI in JCP has not been investigated. METHODS: We designed a double-blinded, randomized, placebo-controlled, crossover trial. Twenty patients with JCP were examined outside the pollen season (UMIN000008410). Nasal provocation with paper discs containing extracts of Japanese cedar pollen was performed once a day for 3 consecutive days. Onset of nasal symptoms was monitored over 15 min after each provocation. The levels of eosinophil cationic protein (ECP) and tryptase in nasal secretions were examined. Fluticasone furoate nasal spray or placebo treatment was started one day before the first provocation. RESULTS: In the placebo group, 25% of the patients showed onset of nasal symptoms following provocation on the first day. In addition, 75% and 68% of the patients showed symptom onset on the second and third day of provocation, respectively. After the first provocation, the levels of ECP and tryptase in nasal secretions were significantly increased. These increases were seen not only in symptomatic but also in asymptomatic subjects in response to provocation, and the levels were similar between these subjects. Prophylactic treatment with fluticasone significantly suppressed the increase in nasal ECP and tryptase associated with repeated provocations. CONCLUSIONS: These results suggest that pre-onset activation of eosinophils and mast cells is present in experimental JCP, and that prophylactic treatment with intranasal corticosteroids has the potential to control such activation.

BACKGROUND: Toll-like receptor 3 (TLR3) is expressed in upper airways, however, little is known regarding whether Toll-like receptor 3 (TLR3) signals exert a regulatory effect on the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP), especially on eosinophilic inflammation. We sought to investigate the effect of Poly(IC), the ligand for TLR3, on cytokine production by dispersed nasal polyp cells (DNPCs). METHODS: DNPCs were pretreated with or without Poly(IC), and were then cultured in the presence or absence of staphylococcal enterotoxin B (SEB), following which the levels of IL-5, IL-10, IL-13, IL-17A and interferon (IFN)-γ in the supernatant were measured. To determine the involvement of IL-10 and cyclooxygenase in Poly(IC)-mediated signaling, DNPCs were treated with anti-IL-10 monoclonal antibody and diclofenac, the cyclooxygenase inhibitor, respectively. Poly(IC)-induced prostaglandin E2 (PGE2) production was also determined. RESULTS: Exposure to Poly(IC) induced a significant production of IL-10, but not of IL-5, IL-13, IL-17A or IFN-γ by DNPCs. Pretreatment with Poly(IC) dose-dependently inhibited SEB-induced IL-5, IL-13 and IL-17A, but not IFN-γ production. Neutralization of IL-10 significantly abrogated the inhibitory effect of Poly(IC). Treatment with diclofenac also abrogated the inhibitory effect of Poly(IC) on SEB-induced IL-5 and IL-13 production. However, unlike exposure of diclofenac-treated DNPCs to lipopolysaccharide, the ligand for TLR4, exposure of these cells to Poly(IC) did not enhance IL-5 or IL-13 production. Poly(IC) did not significantly increase PGE2 production by DNPCs. CONCLUSIONS: These results suggest that TLR3 signaling regulates eosinophilia-associated cytokine production in CRSwNP, at least in part, via IL-10 production.

CONCLUSIONS: The nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome plays an important role in the pathogenesis of middle ear diseases. Modulation of inflammasome-mediated inflammation may be a novel therapeutic strategy for cholesteatoma and chronic otitis media. OBJECTIVE: NLRP3 inflammasome is a critical molecule mediating interleukin (IL)-1β responses. However, the expression of NLRP3 in the pathogenesis of cholesteatoma and chronic otitis media has not been fully examined. This study sought to assess the expression of NLRP3, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain and a pyrin domain), and caspase-1 in middle ear tissues in patients with cholesteatoma or chronic otitis media. METHODS: Middle ear tissue samples were obtained from patients with cholesteatoma or chronic otitis media. Control middle ear samples were collected during cochlear implant surgery of patients without middle ear inflammation. The expression of NLRP3, ASC, and caspase-1 were examined by reverse transcription polymerase chain reaction (RT-PCR) assay and immunohistochemical study. RESULTS: The levels of mRNA of NLRP3, ASC, and caspase-1 were significantly elevated in cholesteatoma and chronic otitis media as compared with that of normal controls. The proteins of NLRP3, ASC, and caspase-1 were observed in infiltrating inflammatory cells in cholesteatoma and chronic otitis media.

BACKGROUND: A close relationship between upper and lower respiratory tract diseases has been reported. The purpose of this study was to evaluate lung function in patients with chronic rhinosinusitis (CRS) who have never smoked. METHODS: A total of 208 patients with CRS were enrolled in this study. Of these subjects, 96 patients were ever smokers and 112 patients were never smokers. CRS patients with lower pulmonary diseases including chronic obstructive pulmonary disease (COPD) and asthma were excluded from this study. Age-matched normal control subjects (n = 55) who were never smokers were also recruited. Pulmonary function testing was performed using spirometry. Lund-Mackay computed tomography (CT) score, peripheral blood eosinophil count, and immunoglobulin E (IgE) level in serum samples were examined. Nasal obstruction was evaluated by active anterior rhinomanometry. RESULTS: CRS patients who were ever smokers have decreased lung function. Never-smoking patients with CRS also showed significant obstructive lung function changes as compared with normal controls. No significant correlation was detected between the clinical parameters (CT score, eosinophil count, IgE level, and nasal resistance) and lung function. CONCLUSION: Asymptomatic obstructive lung function changes were observed in never-smoking patients with CRS. Our findings suggest that patients with CRS should be followed carefully in order to detect lung diseases.

BACKGROUND: Recent studies have revealed that Staphylococcus aureus and its components participate in the pathogenesis of eosinophilic airway diseases, such as chronic rhinosinusitis with nasal polyps. OBJECTIVE: We sought to determine whether staphylococcal protein A (SpA) from S aureus regulated cellular responses in nasal polyps, especially when coupled to immunoglobulins in immune complexes (ICs). METHODS: Dispersed nasal polyp cells (DNPCs) or peripheral blood monocytes were cultured in vitro with SpA in the presence or absence of IgG, and IL-5, IL-13, IFN-γ, IL-17A, and IL-10 levels were measured in the supernatants. The effect of SpA exposure on staphylococcal enterotoxin B-induced cytokine production by DNPCs in the presence and absence of IgG, IgA, and autologous serum was also examined. RESULTS: Exposure to SpA induced DNPCs to produce significantly higher IL-10, IL-13, and IL-17A levels than DNPCs without SpA, although the magnitude of the IL-17A increase was less than that of IL-10 and IL-13. SpA induced IL-10 production mainly from adherent DNPCs, and this was significantly enhanced in the presence of IgG; similar results were observed in peripheral blood monocytes. IC formation between SpA and IgG (SpA-IgG ICs) was confirmed by using native polyacrylamide gel electrophoresis. SpA-IgG ICs, but not SpA alone, almost completely suppressed staphylococcal enterotoxin B-induced IL-5, IL-13, IFN-γ, and IL-17A production by DNPCs; similar inhibition was observed in DNPCs treated with SpA in the presence of either IgA or autologous serum. CONCLUSIONS: Our results suggest that SpA can regulate the pathogenesis of enterotoxin-induced inflammation in patients with chronic rhinosinusitis with nasal polyps through coupling to immunoglobulins.

HYPOTHESIS: Macrophage migration inhibitory factor plays an important role in noise-induced hearing loss. BACKGROUND: Macrophage migration inhibitory factor is an essential factor in axis formation and neural development. Macrophage migration inhibitory factor is expressed in the inner ear, but its function remains to be elucidated. METHODS: Macrophage migration inhibitory factor-deficient mice (MIF(-/-) mice) were used in this study. Wild-type and MIF(-/-) mice received noise exposure composed of octave band noise. Auditory brainstem response thresholds were examined before (control) and at 0, 12, and 24 hours and 2 weeks after the intense noise exposure. Morphological findings of cochlear hair cells were investigated using scanning electron microscopy. Histopathological examination with hematoxylin and eosin staining and TUNEL assay were also performed. RESULTS: In both the wild-type and MIF(-/-) mice, acoustic overstimulation induced significant hearing loss compared with the control level. Two weeks after the intense noise exposure, the MIF(-/-) mice had an increased hearing threshold compared with the wild-type mice. Scanning electron microscopy demonstrated that the outer hair cells in the MIF(-/-) mice were affected 2 weeks after noise exposure compared with the wild-type mice. TUNEL-positive cells were identified in the organ of Corti of the MIF(-/-) mice. CONCLUSION: The MIF(-/-) mice had prolonged hearing loss and significant loss of cochlear hair cells after intense noise exposure. Macrophage migration inhibitory factor may play an important role in recovery from acoustic trauma. Management of macrophage migration inhibitory factor may be a novel therapeutic option for noise-induced hearing loss.

BACKGROUND: In contrast to Staphylococcus aureus-derived superantigenic exotoxins, the role of non-superantigenic exotoxins in the pathogenesis of eosinophilic airway diseases remains obscure. We sought to characterize S. aureus alpha-toxin-induced cellular responses in chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS: Dispersed nasal polyp cells and uncinate tissue cells were prepared from patients with CRS with and without nasal polyps, respectively. Cells were incubated with various concentrations of alpha-toxin or staphylococcal enterotoxin B and then the levels of IL-5, IL-13, IFN-γ, IL-17A, and IL-10 in the cell supernatants were determined. The pathophysiological significance of alpha-toxin-induced cytokine production was also determined including radiological severity of rhinosinusitis, tissue and blood eosinophilia, serum total IgE level, and 1-s forced expiratory volume/forced vital capacity ratio (FEV1/FVC). RESULTS: Nasal polyp cells produced substantial amounts of IL-5, IL-13, IFN-γ, IL-17A, and IL-10 in response to alpha-toxin. Cytokine production was higher in nasal polyp cells than in uncinate tissue cells. The potency of alpha-toxin in stimulating IL-5, IL-13, and IL-10 production was comparable to that of enterotoxin. Alpha-toxin-induced IFN-γ, IL-17A, and IL-10 production significantly and negatively correlated with the degree of eosinophil infiltration into nasal polyps. Conversely, alpha-toxin-induced IFN-γ and IL-10 production significantly and positively correlated with FEV1/FVC. IL-10 production was significantly lower in asthmatic patients compared to non-asthmatics CONCLUSIONS: S. aureus-derived alpha-toxin can provoke cellular responses in nasal polyps. These responses, especially failure to synthesize IL-10, may play a role in the pathophysiology of CRSwNP.

BACKGROUND: The relationship between upper and lower airway diseases has been reported. However, the pulmonary function of patients with chronic rhinosinusitis (CRS) has not been fully examined. METHODS: Pulmonary function was measured in 273 patients with CRS and 100 age-matched normal control subjects. No patients with chronic obstructive pulmonary disease (COPD) were included in this study. The patients with CRS were divided into 8 subgroups based on the presence of asthma, sensitization to common inhaled antigens, and nasal polyposis. The relationships between pulmonary function and clinical parameters, including radiographic severity of CRS according to the Lund-Mackay computed tomography (CT) staging system, eosinophil count in the peripheral blood, and serum total immunoglobulin E (IgE) levels, were assessed. RESULTS: In pulmonary function testing, the CRS patients had affected pulmonary function. The CRS patients without asthma showed latent obstructive pulmonary function changes when compared to normal controls. No significant correlations were observed between pulmonary function and any clinical parameters (Lund-Mackay CT staging score, eosinophil count in the peripheral blood, and serum total IgE levels). CONCLUSION: CRS patients had significant obstructive lung function changes regardless of the presence of asthma. The patients with CRS who had not been clinically diagnosed as having lower respiratory tract diseases might have had subclinical lower airway diseases. Therefore, clinicians should be aware of pulmonary function and lower lung diseases in patients with CRS.

Interleukin (IL)-17A is a major cytokine produced by Th17 cells, which are associated with chronic inflammations. The local expression of IL-17A in allergic rhinitis (AR) remains to be characterized. We sought to determine the role of IL-17A expression in human inferior turbinate mucosa in the pathophysiology of AR. Inferior turbinate mucosa was sampled from medical treatment-resistant, surgery-required patients with perennial AR (PAR, n = 21), nonallergic rhinitis with eosinophilia syndrome (NARES, n = 7), and nonallergic hypertrophic rhinitis (HR, n = 13). IL-17A expression was determined with immunohistochemical staining. The mean number of IL-17A(+) cells and eosinophils per field were counted. Total serum immunoglobulin E (IgE) levels, blood eosinophil count, and forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) ratio were also examined in each patient. IL-17A was primarily expressed in infiltrating inflammatory cells. The number of IL-17A(+) cells in nasal mucosa was significantly higher in the PAR group compared with HR (p = 0.002) and NARES (p = 0.021) groups. There was a significant and positive correlation between the number of IL-17A(+) cells and total nasal symptom score (rho = 0.403; p = 0.011), especially sneezing score (rho = 0.471; p = 0.003). The number of IL-17A(+) cells was significantly and positively correlated with the degree of eosinophil infiltration (rho = 0.623; p < 0.001), but not with total serum IgE levels (rho = 0.284; p = 0.098), blood eosinophil counts (rho = 0.302; p = 0.056), or FEV1/FVC ratio (rho = 0.092; p = 0.569). The present study provides evidence that IL-17A expression in the nasal mucosa is associated with the pathophysiology of AR, including disease severity and nasal eosinophilia.

BACKGROUND: Statistically significant results of medical intervention trials are not always clinically meaningful. We sought to estimate the minimal clinically important difference (MCID) (the smallest change in a given endpoint that is meaningful to a patient) during seasonal alteration of Japanese cedar/cypress pollinosis (JCCP). METHODS: Results of a double-blinded, placebo-controlled trial of JCCP patients conducted between 2008 and 2010 were analyzed using an anchor-based method in which a face scale for Japanese rhinoconjunctivitis quality-of-life questionnaire (JRQLQ) was set as an anchor. MICDs were calculated as changes of average scores, including those for naso-ocular symptoms with 5 items in diary cards (T5SS), naso-ocular symptoms with 6 items (T6SS) and QOL with 17 items on the JRQLQ when face scale scores either improved or deteriorated by one point. RESULTS: In 2009 and 2010, 3,698 and 374, respectively, grains/cm(2) of pollens were dispersed. The MCIDs for T5SS in 2009 and 2010 were 1.426 (0.285 per item) and 1.441 (0.288), respectively. The MCIDs for T6SS were 4.115 (0.686) and 3.183 (0.531) in 2009 and 2010, respectively. The MCIDs for QOL were 10.469 (0.616) and 6.026 (0.354) in 2009 and 2010, respectively. CONCLUSIONS: For T5SS in the diary, T6SS and QOL in JRQLQ, unit differences of 1.5 (0.3 per item), 3.6 (0.6) and 8.2 (0.5), respectively, were considered clinically meaningful by JCCP patients. The MCID for symptoms recorded in the diary was stable irrespective of the dispersed pollen level.

OBJECTIVES/HYPOTHESIS: Granulocyte/macrophage colony-stimulating factor is important in the pathogenesis of acute and chronic inflammatory disease. We hypothesized that granulocyte/macrophage colony-stimulating factor plays a pivotal role in middle ear inflammation and that neutralization of granulocyte/macrophage colony-stimulating factor would inhibit neutrophil migration into the middle ear and production of inflammatory mediators. STUDY DESIGN: Animal experiment. METHODS: We used transtympanic administration of lipopolysaccharide, a major component of gram-negative bacteria, into mice to induce an experimental otitis media. Control mice received injection of phosphate-buffered saline into the middle ear cavity. Mice were systemically treated with granulocyte/macrophage colony-stimulating factor neutralizing antibody or control immunoglobulin G via intraperitoneal injection 2 hours before transtympanic injection of lipopolysaccharide or phosphate-buffered saline. Middle ear effusions were collected. Concentrations of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, keratinocyte chemoattractant, and macrophage inflammatory protein-2 in middle ear effusions were measured by enzyme-linked immunosorbent assay. Histologic examination of the middle ear was also performed. RESULTS: Transtympanic injection of lipopolysaccharide upregulated levels of granulocyte/macrophage colony-stimulating factor, IL-1β, TNF-α, keratinocyte chemoattractant, and macrophage inflammatory protein-2 in the middle ear. Concentrations of cytokines and chemokines were significantly decreased in mice injected with granulocyte/macrophage colony-stimulating factor neutralizing antibody. Infiltration of inflammatory cells into the middle ear cavity induced by lipopolysaccharide was also significantly reduced by neutralization of granulocyte/macrophage colony-stimulating factor. CONCLUSIONS: Systemic injection of granulocyte/macrophage colony-stimulating factor neutralizing antibody inhibits the middle ear inflammation induced by lipopolysaccharide in mice. Our findings suggest that granulocyte/macrophage colony-stimulating factor may offer a novel therapeutic target for the management of intractable otitis media.

BACKGROUND: Interleukin-18 (IL-18) is a member of the IL-1 cytokine family that affects chronic inflammation. We sought to characterize IL-18 expression and investigate its release during chronic rhinosinusitis (CRS). METHODS: The expression of IL-18 in nasal polyps (NPs) and uncinate tissues (UTs) from both CRS and non-CRS patients was examined via immunohistochemistry. After culturing dispersed NP cells (DNPCs) with or without various stimulations, IL-18 levels were measured in the culture supernatants. Furthermore, the effect of IL-18 neutralization on staphylococcus enterotoxin B (SEB)-induced cytokine production was also examined. RESULTS: Similar expression of IL-18 in the epithelial layers was observed between the NPs and UTs. However, there was a significantly higher number of IL-18(+) cells in the lamina propria from NPs compared to UTs without CRS. This increased number was significantly correlated with the radiological severity of sinusitis and local eosinophilia. After the dispersion, IL-18 was spontaneously released by NP cells in a phase-dependent manner. While SEB, fungal antigens, and TLR agonists did not enhance the release, exposure to protease or one cycle of a freeze-and-thaw treatment did induce release of IL-18 from rested DNPCs. In addition, neutralization of IL-18 significantly suppressed SEB-induced IL-5, IL-13, and IFN-γ, but not IL-17A production. CONCLUSIONS: These results suggest that the pro-inflammatory effect of IL-18 released by danger signals may be involved in the pathogenesis of CRS, which includes eosinophilic inflammation and NP formation, via the augmentation of both Th2- and Th1-associated cytokine production.

BACKGROUND: The usefulness of early interventional treatment (EIT) with intranasal corticosteroids (INSs) compared with postonset treatment (POT) has not been clarified. OBJECTIVES: To study the efficacy and safety of EIT with INSs compared with POT and placebo in Japanese cedar/cypress pollinosis. METHODS: We designed a 3-armed, double-blinded, randomized, placebo-controlled trial. Patients received mometasone furoate nasal spray (EIT group: n = 25), placebo (n = 25), or 4 weeks of placebo followed by 8 weeks of mometasone (POT group: n = 25) for a 12-week period starting on February 1, 2011. The primary end point was the comparison of the total nasal symptom score (TNSS) among the 3 groups. Total ocular symptom score (TOSS), total naso-ocular symptom score (TSS), Allergic Rhinitis and Its Impact (ARIA) on Asthma classification, and safety were the main secondary end points. RESULTS: The placebo and POT groups, but not the EIT group, had a significant exacerbation of TNSS and TOSS soon after the start of pollen counts being high on consecutive days. The 12-week mean TSS in the EIT group (score, 2.3) was significantly lower than in the placebo (5.0; P < .01) and POT (3.9; P = .03) groups. All patients in the placebo and POT groups were classified as having persistent rhinitis, whereas 80% of the EIT group met the ARIA classification criteria (P = .03). The quality-of-life score and nasal eosinophil cationic protein levels were lower in the EIT and POT groups compared with the placebo group. Daytime sleepiness, smell disturbance, and the mean dose of loratadine taken as the rescue medication were similar. Treatment with mometasone was well tolerated. CONCLUSION: EIT with INSs is superior to POT in controlling pollinosis.

Background Lipopolysaccharide (LPS) has shown heterogeneous effects on eosinophilic inflammation in airways. However, little is known about how LPS regulates pathogenesis of chronic rhinosinusitis with nasal polyps, a major form of eosinophilic inflammation in the upper airway. Objective We sought to investigate the effect of LPS on cytokine production by dispersed nasal polyp cells (DNPCs). Methods Either diclofenac-treated or untreated DNPCs were cultured with or without staphylococcal enterotoxin B (SEB) in the presence or absence of LPS, after which the levels of IL-5, IL-13, IL-17A and IFN-gamma within the supernatant were measured. The effects of PGE(2) on LPS-induced responses by diclofenac-treated DNPCs were also examined. LPS-induced PGE(2) production and mRNA expression of COX-1, COX-2 and microsomal PGE(2) synthase-1 (m-PGES-1) were measured. Results Staphylococcal enterotoxin B induced IL-5, IL-13, IL-17A and IFN-gamma production by DNPCs. Pre-treatment with LPS prior to SEB stimulation inhibited production of these cytokines. After stimulation with LPS, PGE(2) production and expression of COX-2 and m-PGES-1 mRNA by DNPCs increased significantly. In the presence of diclofenac, the suppressive effects of LPS were eliminated. LPS pre-treatment enhanced SEB-induced IL-5, IL-13 and IL-17A production in diclofenac-treated DNPCs, while addition of PGE(2) inhibited IL-5, IL-13 and IFN-gamma production. LPS alone induced IL-5, IL-13 and IFN-gamma production by diclofenac-treated DNPCs, while the addition of EP2 and EP4 receptor-selective agonists, as well as PGE(2) itself, inhibited IL-5 and IL-13 production. Conclusions and Clinical Relevance These results suggest that the regulatory effects of LPS on eosinophilic airway inflammation are controlled via the COX-2/PGE(2) axis. For clinical implications, indiscreet use of non-steroidal anti-inflammatory drugs should be avoided in patients with chronic rhinosinusitis with nasal polyps.

BACKGROUND: Little is known about the safety and effectiveness of early interventional treatment (EIT) with intranasal corticosteroids for seasonal allergic rhinitis. We designed a double-blinded, randomized, placebo-controlled 12-week trial of EIT with mometasone furoate nasal spray (MFNS) for Japanese cedar/cypress pollinosis (JCCP). METHODS: A total of 50 JCCP patients received MFNS (200μg once daily: n = 25) or placebo (n = 25) starting on February 1, 2010. Treatments continued until the end of April. The primary endpoint was the comparison of the total nasal symptom score (TNSS) between the MFNS and placebo groups. The secondary endpoints included comparisons of QOL, daytime sleepiness, nasal ECP levels, and safety. RESULTS: Continuous dispersion of Japanese cedar pollen began on February 22. Although the placebo group showed a significant worsening of symptoms after the start of the continuous dispersion, no worsening occurred in the MFNS group. A significant difference in the TNSS between the two groups was seen starting at 4 weeks after the treatment. Similar results were seen for QOL and sleepiness. Nasal ECP levels in March were significantly lower in the MFNS group. A total of 56% of the MFNS group progressed to a persistent allergic rhinitis state in accordance with the ARIA classification, as opposed to 84% of the placebo group. MFNS was well tolerated, and the plasma cortisol concentrations were similar between the two groups. CONCLUSIONS: EIT with MFNS for JCCP is both safe and effective. This treatment can potentially lessen symptoms and help pollinosis patients remain in the intermittent state.

Otitis media is one of the most common and intractable ear diseases, and is the major cause of hearing loss, especially in children. Multiple factors affect the onset or development of otitis media. Prostaglandin D2 is the major prostanoid involved in infection and allergy. However, the role of prostaglandin D2 and prostaglandin D2 receptors on the pathogenesis of otitis media remains to be determined. Recent studies show that D prostanoid receptor (DP) and chemoattractant receptor-homologous molecule expressed on T helper type 2 (Th2) cells (CRTH2) are major prostaglandin D2 receptors. In this study, homozygous DP single gene-deficient (DP-/-) mice, CRTH2 single gene-deficient (CRTH2-/-) mice and DP/CRTH2 double gene-deficient (DP-/- CRTH2-/-) mice were used to investigate the role of prostaglandin D2 and its receptors in otitis media. We demonstrate that prostaglandin D2 is induced by lipopolysaccharide (LPS), a major component of Gram-negative bacteria, and that transtympanic injection of prostaglandin D2 up-regulates macrophage inflammatory protein 2 (MIP-2), interleukin (IL)-1β and IL-6 in the middle ear. We also show that middle ear inflammatory reactions, including infiltration of inflammatory cells and expression of MIP-2, IL-1β and IL-6 induced by LPS, are reduced significantly in DP-/- mice and DP-/- CRTH2-/- mice. CRTH2-/- mice display inflammatory reactions similar to wild-type mice. These findings indicate that prostaglandin D2 may play significant roles in LPS-induced experimental otitis media via DP. © 2010 The Authors.

BACKGROUND: Recent investigations have revealed that staphylococcal enterotoxins (SEs), COX metabolism, or both might participate in the pathogenesis of eosinophilic airway diseases, such as chronic rhinosinusitis with nasal polyposis. OBJECTIVE: We sought to determine whether COX metabolism, especially prostaglandin (PG) E(2), plays a significant role in SE-induced cellular responses in nasal polyps. METHODS: Dispersed nasal polyp cells (DNPCs) were prepared from nasal polyps by means of enzymatic digestion. DNPCs were cultured with SEB in the presence or absence of COX inhibitors (diclofenac and indomethacin) for 72 hours; then the levels of IL-5, IL-13, RANTES, and eotaxin in the supernatants were measured. The effect of PGE(2) on SEB-induced responses by diclofenac-treated DNPCs was examined, especially in terms of receptor specificity. RESULTS: DNPCs produced significant amounts of IL-5, IL-13, and RANTES in response to SEB. COX inhibitors significantly increased the production of these cytokines. The degree of local eosinophilia was significantly and positively correlated with the changes in IL-5 production induced by diclofenac treatment. PGE(2) significantly and dose-dependently inhibited SEB-induced IL-5, IL-13, and RANTES production by diclofenac-treated DNPCs. E-prostanoid (EP) 2 receptor-selective agonist strongly inhibited the production of all 3 cytokines. EP3 and EP4 receptor-selective agonists partially suppressed these responses, whereas EP1 receptor-selective agonist did not. Interestingly, all of the combined treatments with 2 of the 4 EP receptor-selective agonists significantly inhibited the SEB-induced responses by diclofenac-treated DNPCs. CONCLUSIONS: These results suggest that PGE(2) inhibits the pathogenesis of SEB-induced eosinophilic inflammation primarily through the EP2-mediated pathway in patients with chronic rhinosinusitis with nasal polyposis.

BACKGROUND: Prostaglandin D(2) (PGD(2)) participates in airway inflammation. We reported that levels of hematopoietic-type PGD(2) synthase (h-PGDS) in sinonasal tissues may play an important role in the pathophysiology of chronic rhinosinusitis (CRS). Two PGD(2) receptors have been isolated, DP and CRTH2, but whether they participate in CRS remains unclear. We sought to determine the expression and characterization of DP and CRTH2 in CRS. METHODS: Expression of DP and CRTH2 in nasal polyps (NP) and uncinate process mucosae (UPM) was examined by in situ hybridization and immunohistochemistry and evaluated by real-time quantitative PCR. h-PGDS, IL-5, eotaxin and RANTES expression was also determined. In addition, the effect of PGD(2) on the expression of both receptors in UPM was assessed. RESULTS: DP was widely expressed, not only in infiltrating inflammatory cells but also in constitutive cells such as vascular endothelial cells and ciliated columnar epithelia. CRTH2 was selectively expressed in inflammatory cells and some glands. Significantly greater levels of DP mRNA and conversely decreased levels of CRTH2 mRNA were observed in NP compared with UPM. DP and CRTH2 mRNA levels were not only positively and inversely correlated with levels of h-PGDS but also with eotaxin, respectively. Furthermore, addition of PGD(2) significantly increased DP expression and conversely reduced CRTH2 expression in UPM. CONCLUSIONS: These results suggest that distinct expression of DP and CRTH2 is associated with the pathophysiology of CRS, including NP formation, and the expression of these receptors may be regulated by h-PGDS and PGD(2).

BACKGROUND: Nasogastric tubes (NGT) are used widely for feeding and decompressions of stomach, but they are associated with several complications and discomfort. When prolonged use of NGT is required, percutaneous endoscopic gastrostomy (PEG) should be considered. However, PEG is not feasible for patients with previous gastrectomy. We have performed tube cervical esophagostomy (TCE) for such difficult cases of PEG. METHODS: The current study focused on 7 patients requiring TCE for feeding or decompression from 2004 to 2005 at Tottori Municipal Hospital in Japan. RESULTS: The procedure is relatively simply to perform under local anesthesia and significant complications were not experienced. CONCLUSIONS: Feeding or decompressive TCE is useful alternative procedure in patients where PEG is not feasible or unacceptable.

<p>形質細胞腫瘍は，B細胞の最終分化形態である形質細胞がモノクローナル性に増殖し，骨または髄外組織に局所的に発生する腫瘍性疾患である。髄外性形質細胞腫は骨髄以外の組織に発生する形質細胞腫で，頭頸部領域に好発することが知られており耳鼻咽喉科医として念頭に置くべき疾患の1つと思われる。症例は83歳男性。主訴は左鼻出血・左鼻閉。半年前からの反復する左鼻出血・左鼻閉で近医を受診し，左鼻腔に腫瘤を認め当院へ紹介となった。左鼻腔内には表面平滑な腫瘤が充満しており，副鼻腔CT・MRIでは左篩骨洞から鼻腔にかけて占拠性病変を認めた。左鼻腔腫瘤の生検結果は炎症性変化の疑いとの診断であった。左鼻閉改善の希望があり，局所麻酔下で左鼻茸摘出術を施行し，病理組織検査は形質細胞腫瘍であった。血中M蛋白や尿中Bence-Jones蛋白は陰性，骨髄生検は正常で骨髄腫の所見は認めず，髄外性形質細胞腫の診断となった。FDG-PETでは左鼻副鼻腔内のみにFDG集積を認め，頸部リンパ節転移や遠隔転移は認めなかった。全身麻酔下で左内視鏡下鼻副鼻腔手術を施行した。腫瘍の周囲組織への浸潤は認めず肉眼的には完全摘出したが，安全域をとっていないため，術後放射線治療を追加した（total 46 Gy/23 fr）。その後は再発なく外来にて経過観察中である。髄外性形質細胞腫は数年以上経過した後に多発性骨髄腫へ移行することが報告されており，局所再発や遠隔転移の有無も含めて長期にわたり厳重な経過観察が必要と思われる。</p>

アレルギー性真菌性鼻副鼻腔炎(Allergic Fungal Rhinosinusitis:AFRS)は真菌に対するアレルギー機序により生じる難治性の副鼻腔炎として知られている。以前は欧米からの報告が中心であったが、本邦でも昨今増加傾向であるがまだ不明な点も多い。真菌が副鼻腔に寄生、増殖し、副鼻腔でアレルギー反応が起こることで副鼻腔粘膜に好酸球が浸潤する。その結果、難治性の鼻ポリープおよび好酸球性ムチンが生じ、手術を行なっても再発しやすく、臨床的にも問題となることが多い、耳鼻咽喉科医にとって注意を要する疾患である。今回、AFRSについて解説するとともに、AFRSに対する術後のアレルゲン免疫療法について紹介する。(著者抄録)

鼻噴霧用ステロイド薬はアレルギー性鼻炎に対して強力な抗炎症作用を示す。花粉症の本格発症前の最小持続炎症の制御という観点から,これまで,鼻噴霧用ステロイド薬は花粉症初期治療薬としての有用性が議論されていたが,最新版の鼻アレルギー診療ガイドライン(2016年版)からは,鼻噴霧用ステロイド薬は初期療法の1つとして記載されるようになった。自験例も含めいくつかのプラセボ対照二重盲検比較試験において,鼻噴霧用ステロイド薬によるスギ・ヒノキ花粉症に対する初期治療は,プラセボと比較して症状およびQOLの増悪を有意に抑制した。一方,安全性に関しては実薬とプラセボとの間に有意な差を認めなかった。さらに発症後治療と比較しても花粉の本格飛散後の鼻眼症状の増悪を有意に抑制した。以上の結果からは鼻噴霧用ステロイド薬による初期治療は有効かつ安全な治療法であることが明らかとなった。しかし,初期治療の適切な開始時期や飛散花粉数による効果の変化など今後の検討も必要である。(著者抄録)

<p>髄膜脳瘤は頭蓋骨の欠損孔から頭蓋内容が頭蓋外に脱出する疾患である。先天性の骨欠損による髄膜脳瘤は後頭部に多く発生し，頭蓋底に発生することは稀である。今回，前頭洞後壁の骨欠損部から鼻腔へと脱出した前頭洞型頭蓋底髄膜脳瘤症例に対して，前頭開頭術と経鼻内視鏡下鼻副鼻腔手術を併用した切除術を施行し，良好な経過を得たので報告する。症例は40歳，男性。感冒薬を内服後に意識障害を認め，近医総合病院へ救急搬送された。横紋筋融解症を認め，透析などの加療が施行された。また，頭部MRIで左篩骨洞・前頭洞陰影と脳室拡大を認めた。髄液鼻漏所見を認めたため同院耳鼻咽喉科へ紹介され，左鼻腔内腫瘤の生検を行ったところ脳組織とのことであった。横紋筋融解症が改善したのちも意識障害が遷延するため，精査加療目的で当院脳神経外科へ転院となった。意識障害はフェノバルビタールナトリウムなどの点滴静注治療により軽快した。髄膜脳瘤に対して前頭開頭術と内視鏡下鼻副鼻腔手術を併用した切除手術と前頭蓋底再建術を施行した。術後2年を経過して髄膜脳瘤の再発は認められない。近年，頭蓋底髄膜脳瘤に対しては内視鏡による経鼻的アプローチのみで切除術を行う報告が増加している。本症例は前頭洞後壁に骨欠損部があり，内視鏡下操作のみでは硬膜再建が困難と判断した。髄膜脳瘤は比較的まれな疾患であり，症例によって適切なアプローチ法を検討することが必要と思われた。</p>

急性浸潤型副鼻腔真菌症は眼窩や脳内に進展し極めて難治性で予後不良な疾患である。今回，急性リンパ性白血病の寛解導入療法中に発症し，不幸な転機となった鼻脳型ムーコル症の一例を経験したため，文献的考察を加えて報告する。症例は74歳，女性。当院血液内科で急性リンパ性白血病と診断され，入院2日目より寛解導入療法を開始した。治療開始後から徐々に左視力低下，軽い左眼周囲の痛みを感じ，入院21日目より左眼瞼腫脹，複視を認めるようになり，25日目に眼科受診。左眼球運動の全方向への障害，左眼圧の上昇，左視力低下を認め，CTで副鼻腔炎からの左眼窩蜂窩織炎の疑いにて同日当科紹介受診した。両側鼻内，特に左鼻副鼻腔粘膜は大部分が黒色で壊死性変化をきたしており，病理検査でムーコル症の診断となった。診断後からリポソーマルアムホテリシンBの全身投与を開始した。左眼球摘出も含めたデブリードマンを勧めるも，患者とその家族が拒否したため，入院32日目に鼻副鼻腔内の病変部位を内視鏡下鼻副鼻腔手術にて可及的に除去した。左眼窩内への操作は行わなかった。術後からアムホテリシンBによる鼻腔内洗浄を開始した。入院33日目には左眼光覚消失，37日目より口蓋の穿孔，鞍鼻が生じた。入院96日目に急性細菌性肺炎生じ，98日目に永眠された。拡大手術を行い，薬物治療を併用したとしても根治する保証はない非常に予後の悪い疾患のため，できるだけの早期診断と治療開始が必要と考えられた。

In Japan, pollen from Japanese cedar (Cryptomeria japonica) and Japanese cypress (Chamaecyparis obtusa), species that have been planted in approximately 4.5 and 2.6 million ha, respectively, is spread wide through aerial dispersion in spring. Consequently, Japanese cedar/cypress pollinosis (JCCP) is the major phenotype of allergic rhinitis (AR) in Japan, and significantly impairs the quality of life (QOL). Compared with Japanese cedar pollinosis, the pathogenesis and management of Japanese cypress pollinosis remain unclear. Cha o 1 and Cha o 2 are major allergens in Japanese cypress pollen, and have considerable homology with Cry j 1 and Cry j 2, respectively, in Japanese cedar pollen. Several other components were recently identified in Japanese cypress pollen, and may facilitate allergic inflammation via IgE-independent mechanisms. Allergen-specific CD4 + Th2 cells producing interleukin (IL)-4, IL-5, IL-13 and IL-31 are believed to play central roles in the pathogenesis of AR. The major human T cell epitopes in Cha o 1 and Cha o 2 have been identified. Compared with those in Cry j 1 and Cry j 2, both common and unique T cell epitopes in the cypress allergens have been characterized. Peripheral blood mononuclear cells (PBMCs) produced these Th2-type cytokines in response to a crude extract of Japanese cypress pollen. Among these cytokines, induction of antigen-specific IL-5 and IL-31 production is closely associated with the onset and exacerbation of Japanese cypress pollinosis, respectively. Allergen-specific immunotherapy using a standardized extract of Japanese cedar pollen is effective in controlling both naso-ocular symptoms and QOL during the period of cedar pollen dispersion, although the significant efficacy tends to be reduced during the period of cypress pollen dispersion, especially when the pollen dispersion is high. IL-5 production by PBMCs in response to the crude extract of Japanese cypress pollen did not differ significantly between patients with and without the immunotherapy, suggesting that unique component(s) in Japanese cypress pollen can induce IL-5 production, which is not fully suppressed by immunotherapy with the standardized extract of cedar pollen. The Practical Guideline for Management of Allergic Rhinitis in Japan recommends that patients who experience severe symptoms of pollinosis every year should receive early interventional treatment. Although early interventional treatment with a histamine H1 receptor antagonist (H1RA) is effective for Japanese cedar pollinosis, especially at the beginning of the season, this treatment has limitations for Japanese cypress pollinosis when exposure to the pollen is high. Combined therapy with a leukotriene receptor antagonist and/or intranasal corticosteroids may be required to fully control the worsening of JCCP during the cypress pollen season. © 2012 Blackwell Publishing Ltd.
