Background: There are cases of idiopathic interstitial pneumonias (IIPs) that do not meet the diagnostic criteria for connective tissue disease but have clinical features suggestive of autoimmune process. Interstitial pneumonia with autoimmune features (IPAF) was recently proposed as a research concept for these patients. Although several prospective studies on IPAF have been conducted, its clinical significance in cryptogenic organizing pneumonia (COP) remains unclear. Methods: Patients aged ≥20 years with suspected COP were prospectively enrolled between June 2018 and December 2022. Among the enrolled patients, those diagnosed with COP based on computed tomography (CT) and bronchoalveolar lavage (BAL) findings were compared between the IPAF and non-IPAF groups. Results: A total of 56 patients were enrolled in this study. Of these, 30 were diagnosed with COP and included in the analysis. Clinical and serological features were positive in two and six patients, respectively. Each feature was exclusive, and eight patients (26.7%) were diagnosed with IPAF. There were no differences between the IPAF and non-IPAF groups in terms of clinical features, including BAL findings, laboratory data, CT findings, and clinical course. During the one-year follow-up period, the frequency of COP exacerbation did not differ between the IPAF and non-IPAF groups, and no cases of systemic autoimmune disease or death occurred in either group. Conclusions: The COP characteristics of the IPAF and non-IPAF groups are similar in all aspects, and distinguishing between the two groups may be of little significance.

Nuclear protein of the testis carcinoma (NUTC) is a rare and aggressive malignancy. We herein report a case of NUTC in the lung characterized by a bronchial lesion and elevated alpha-fetoprotein levels. A 35-year-old Japanese man presented to our institution with suspected advanced lung cancer based on a histological examination. Subsequently, next-generation sequencing (NGS) yielded a positive BRD4-NUTM1 fusion. In addition, positive NUT immunostaining of the lung biopsy specimen confirmed NUTC in the lungs. Systemic chemotherapy and radiotherapy showed a temporary response, with decreased serum alpha-fetoprotein levels. We highlight this case of a prompt diagnosis by NGS of NUTC in a young individual with a rapidly progressing tumor.

A 55-year-old man presented to our hospital with idiopathic pulmonary fibrosis (IPF). He was registered with the Japan Organ Transplant Network the following year due to disease progression. Treatment with clarithromycin, ethambutol, and rifampicin for complications of Mycobacterium avium pulmonary disease was initiated, but sputum conversion could not be achieved. The administration of an amikacin liposome inhalation suspension (ALIS) resulted in sputum conversion, and single-lung transplantation was performed. ALIS therapy was continued after lung transplantation, and no M. avium disease was observed for 15 months. ALIS may cause M. avium pulmonary disease with additional indications for lung transplantation.

Language：English Publishing type：Research paper (scientific journal)

A 50-year-old man was diagnosed with hypersensitivity pneumonitis caused by the environment of his bar owing to worsening symptoms, laboratory test results, and computed tomography images after an environmental inhalation challenge test. His hypersensitivity pneumonitis exacerbated despite receiving prednisolone 20 mg/day. The patient underwent allogeneic hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen-matched unrelated donor for myelodysplastic syndrome. No exacerbation of hypersensitivity pneumonitis was observed after HSCT. An environmental inhalation challenge test involving exposure to his bar confirmed the remission of hypersensitivity pneumonitis after HSCT. This case demonstrates that hypersensitivity pneumonitis can be remitted by HSCT.

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: Because exacerbation of severe asthma decreases patients' quality of life, this study aimed to identify predictive factors for asthma exacerbation. METHODS: Japanese patients with severe asthma requiring treatment according to the Global Initiative for Asthma (GINA) guidelines ≥ Step 4 between January 2018 and August 2021 were prospectively enrolled and followed up for one year at facilities participating in the Okayama Respiratory Disease Study Group (Okayama Severe Asthma Research Program). RESULTS: A total of 85 patients (29 men and 56 women) were included. The median age was 64 (interquartile range [IQR], 51-72) years. Treatment according to GINA Steps 4 and 5 was required in 29 and 56 patients, respectively, and 44 patients (51.8%) were treated with biologics. The median peripheral-blood eosinophil count, fractional exhaled nitric oxide, IgE level, and percent predicted FEV1 (%FEV1) at enrollment were 204 (IQR, 49-436)/μL, 28 (IQR, 15-43) ppb, 172 (IQR, 56-473) IU/mL, and 80.0 (IQR, 61.1-96.1) %, respectively. Exacerbation during the previous year, asthma control test (ACT) score <20, %FEV1 <60%, and serum IL-10 level >6.7 pg/mL were associated with exacerbation during the observation period. CONCLUSIONS: Exacerbation during the previous year, low ACT score, and low %FEV1 were predictive factors of future exacerbation, even in a cohort with >50% of patients treated with biologics. Furthermore, high serum IL-10 levels might be a new predictive factor.

Language：English Publishing type：Research paper (scientific journal)

The concurrent incidence of lung cancer and tuberculosis is expected to escalate due to the projected growth in the older population. Combination therapy with osimertinib and antituberculosis drugs has not been well-established. We report a case of successful treatment involving the concomitant administration of osimertinib and antituberculosis drugs in an older patient, an 89-year-old female, diagnosed with epidermal growth factor receptor (EGFR)-mutant lung cancer and pulmonary tuberculosis. Accumulating evidence is warranted to develop an optimal treatment strategy for patients with lung cancer and tuberculosis.

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.

A 56-year-old woman who received CD19 chimeric antigen receptor-T cell therapy for refractory diffuse large B-cell lymphoma developed severe coronavirus disease 2019 (COVID-19) and was treated with nirmatrelvir/ritonavir in April 2022. However, she experienced persistent fatigue and cough and fever in June. Computed tomography revealed bilateral ground-glass opacities (GGO), and the patient was treated with corticosteroids for organizing pneumonia after COVID-19. Partial improvement was observed, but new GGO appeared despite corticosteroid therapy. Genome analysis of severe acute respiratory syndrome coronavirus 2 detected Omicron variant BA.1.1.2, which was prevalent at the time of initial infection. The patient was diagnosed with protracted COVID-19 and was treated with remdesivir, molnupiravir, nirmatrelvir/ritonavir, and tixagevimab/cilgavimab. These treatments appeared to contribute to the improvement of protracted COVID-19.

A 55-year-old man with stage IV lung adenocarcinoma was treated with cisplatin, pemetrexed, nivolumab, and ipilimumab. Approximately 100 days after treatment initiation, he became disoriented and presented to the emergency department with a high fever. Blood tests revealed liver and kidney dysfunctions. Subsequently, the patient developed generalized convulsions that required intensive care. He was clinically diagnosed with cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Organ damage was gradually controlled with immunosuppressive drugs, including steroids, and the patient was discharged. Successful treatment is rare in patients with CRS, including ICANS, during immune checkpoint inhibitor treatment for solid tumors.

Pulmonary fibrosis and type-17 immunity. International journal

Satoru Senoo, Hisao Higo, Akihiko Taniguchi, Katsuyuki Kiura, Yoshinobu Maeda, Nobuaki Miyahara

Respiratory investigation 61 ( 5 ) 553 - 562 2023.9

Language：English Publishing type：Research paper (scientific journal)

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.
