RESUMO
Various symptoms emerge as immune-related adverse events of immune checkpoint inhibitor (ICI). A 73-year-old woman, a non-smoker, receiving chemotherapy including atezolizumab for lung adenocarcinoma, presented with fever, bilateral parotid swelling and sicca syndrome after four courses of chemotherapy. Because the lesions were not localized, the diagnosis was ICI-related sialadenitis rather than infectious. Prednisolone improved salivary gland swelling quickly. Six months after the last administration of ICI, there was no obvious progression of lung cancer. To our knowledge, this is the first case of sialadenitis caused by atezolizumab. ICI-related sialadenitis may be a good prognostic marker for lung cancer.
RESUMO
Non-small-cell lung cancer (NSCLC) with comorbid interstitial pneumonia (IP) is a population with limited treatment options and a poor prognosis. Patients with comorbid IP are at high risk of developing fatal drug-induced pneumonitis, and data on the safety and efficacy of molecularly targeted therapies are lacking. KRAS mutations have been frequently detected in patients with NSCLC with comorbid IP. However, the low detection rate of common driver gene mutations, such as epidermal growth factor receptor and anaplastic lymphoma kinase, in patients with comorbid IP frequently results in inadequate screening for driver mutations, and KRAS mutations may be overlooked. Recently, sotorasib and adagrasib were approved as treatment options for advanced NSCLC with KRASG12C mutations. Although patients with comorbid IP were not excluded from clinical trials of these KRASG12C inhibitors, the incidence of drug-induced pneumonitis was low. Therefore, KRASG12C inhibitors may be a safe and effective treatment option for NSCLC with comorbid IP. This review article discusses the promise and prospects of molecular-targeted therapies, especially KRASG12C inhibitors, for NSCLC with comorbid IP, along with our own clinical experience.
RESUMO
Patients with non-small cell lung cancer (NSCLC) are often positive for oncogenic driver mutations, such as EGFR, ALK, BRAF, RET and MET exon 14 skipping mutations (METex14 skipping). Recently, METex14 skipping has become a functional biomarker for NSCLC with the approval of MET kinase inhibitors. Tepotinib is an oral MET kinase inhibitor. Its overall response rate is 46%, and the median duration of the response is 11.1 months. In Japan, companion diagnostics for tepotinib are limited with the ArcherMET and AmoyDx test, but not with Oncomine Dx target test. The present study reports the case of a 60-year-old male patient with lung adenocarcinoma harboring METex14 skipping, which was positive on Oncomine DxTT, but not on ArcherMET. In his sample used for Oncomine DxTT, the read count of MET(13)-MET(15) products was only 46. He was treated with various chemotherapeutic agents, but developed cardiac tamponade due to the progression of the disease of mediastinal lymph node metastases. Tepotinib was administered following pericardial drainage, resulting in an immediate response in all lesions. The majority of the discordant samples between Oncomine DxTT and ArcherMET had read counts <800, and the patient described herein had only 46. Therefore, the results of the present study indicate that the use of tepotinib should be considered even in patients whose METex14 skipping results were negative with ArcherMET, yet positive on Oncomine DxTT, particularly relatively with low lead counts.
RESUMO
BACKGROUND/AIM: Cancer and ischemic stroke are closely associated. Thromboembolism susceptibility in lung cancer may differ depending on oncogenic alterations. However, the clinical characteristics of thromboembolism in patients with BRAF-mutant non-small-cell lung cancer remain unknown. Thus, this study aimed to evaluate the cumulative incidence of thromboembolism in this population and describe such cases in detail. PATIENTS AND METHODS: We retrospectively investigated consecutive patients with BRAF V600E-mutant non-small-cell lung cancer. Cumulative incidence was calculated using a competing risk analysis. RESULTS: Of 10 patients with BRAF-V600E mutant lung cancer, five developed a total of seven thromboembolic events, showing a 1-year cumulative incidence of 43% (95% confidence interval=11-72%). These events consisted of four cancer-related stroke (CRS) events and three venous events including deep vein thrombosis or pulmonary embolism. Of note, most of the early thrombotic events were CRS. Two patients with CRS had multiple brain infarctions during anticancer drug therapy, characterized by high D-dimer levels, resulting in short-term mortality (13 and 22 days after stroke onset). CONCLUSION: A substantial proportion of patients with BRAF V600E-mutant lung cancer experienced thromboembolism during their disease course. CRS of undetermined source may predict a worse prognosis in this population.

Acute exacerbations due to COVID-19 vaccination in patients with interstitial lung disease (ILD) have been reported, but their incidence is unknown. We investigated the incidence of exacerbations of ILD and respiratory symptoms due to the mRNA COVID-19 vaccines. A questionnaire survey was conducted on adverse reactions to the mRNA COVID-19 vaccination in 545 patients with ILD attending our hospital and retrospectively examined whether the eligible patients actually developed acute exacerbations of ILD induced by the vaccine. Of the 545 patients, 17 (3.1%) patients were aware of the exacerbation of respiratory symptoms, and four (0.7%) patients developed an acute ILD exacerbation after vaccination. Of the four patients who experienced exacerbations, two had collagen vascular disease-associated ILD, one had nonspecific interstitial pneumonia, another had unclassifiable idiopathic pneumonia, and none had idiopathic pulmonary fibrosis. Four patients were treated using steroid pulse therapy with a steroid taper, and two of the four also received intravenous cyclophosphamide pulse therapy. Tacrolimus was started in one patient with myositis-associated interstitial lung disease. Eventually, all patients exhibited improvement with immunosuppressive treatment and were discharged. COVID-19 vaccination for patients with ILD should be noted for developing acute exacerbations of ILD with low incidence, although manageable with early diagnosis and treatment.

Objective Interstitial lung disease (ILD) is the most critical manifestation in patients with rheumatoid arthritis (RA). In some cases, ILD may appear before the RA onset. Some patients with an initial diagnosis of idiopathic interstitial pneumonia (IIPs) develop RA; however, few studies have reported on its features, and the details remain unknown. In the present study, the clinical, radiological, and pathological features were evaluated in patients with ILD preceding RA. Methods The clinical, radiological, and pathological features of patients with ILD preceding RA were retrospectively reviewed using the medical records. Patients Ten patients with ILD preceding RA out of 883 IIP patients who underwent a surgical lung biopsy at our hospital from 2004 to 2018 were retrospectively examined. Results The median patient age was 59 (range 50-76) years old, and 7 of the patients were women. The median time from the ILD diagnosis to the RA onset was 50 (range 33-65) months. Regarding the high-resolution computed tomography pattern, the "indeterminate for UIP" pattern was the most popular, and cysts were seen in all cases. Attenuation around the cyst was prominent. Pathological findings showed plasma cell infiltration, bronchus-associated lymphoid tissue (BALT), and bronchiolitis in the lobules. Cellular and destructive bronchiolitis was noticeable in many patients with ILD preceding RA and contributed to the destruction and dilation of the bronchiole. Conclusion In ILD patients with IIP, radiological and pathological findings with increased attenuation around the cysts, prominent inflammatory cell infiltration (especially in plasma cells), an increase in the BALT number, and cellular and destructive bronchiolitis might serve as helpful RA development indicators.

BACKGROUND: The prognosis of lung cancer patients with interstitial lung disease (ILD) is poor, and acute exacerbation (AE) of ILD can occur during chemotherapy as a fatal adverse event. Although AE-ILD development is correlated with various factors, no reports are investigating the disease activity of lung cancer at the time of AE-ILD development. METHODS: All consecutive lung cancer patients with ILD who developed chemotherapy-related AE-ILD within 28 days after the last administration of cytotoxic chemotherapy between 2011 and 2020 were retrospectively reviewed. RESULTS: Among 206 lung cancer patients with ILD who were treated with cytotoxic chemotherapy, 30 patients were included. The median age was 72 years and all patients were men with smoking history. Usual interstitial pneumonia (UIP) and non-UIP patterns of ILD was observed in 17 and 13 patients. Most of AE-ILD occurred during second- or later-line (22/30, 73.3%) and developed within first or second courses during chemotherapy (19/30, 63.3%). Regarding tumor response to chemotherapy at AE-ILD development, majority of patients (18 patients, 60.0%) experienced progressive disease and only one patient (3.3%) experienced a partial response. Notably, 27 patients (90.0%) did not exhibit any tumor shrinkage of the thoracic lesions. CONCLUSION: Lung cancer was uncontrolled with cytotoxic chemotherapy at the time of AE-ILD development. Although AE-ILD during chemotherapy has been generally discussed in terms of drug-specific adverse effects, uncontrolled lung cancer may be also correlated with AE-ILD development.

The best available evidence and the predictive value of computed tomography (CT) findings for prognosis in patients with acute respiratory distress syndrome (ARDS) are unknown. We systematically searched three electronic databases (MEDLINE, CENTRAL, and ClinicalTrials.gov). A total of 410 patients from six observational studies were included in this systematic review. Of these, 143 patients (34.9%) died due to ARDS in short-term. As for CT grade, the CTs used ranged from 4- to 320-row. The index test included diffuse attenuations in one study, affected lung in one study, well-aerated lung region/predicted total lung capacity in one study, CT score in one study and high-resolution CT score in two studies. Considering the CT findings, pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 62% (95% confidence interval [CI] 30-88%), 76% (95% CI 57-89%), 2.58 (95% CI 2.05-2.73), 0.50 (95% CI 0.21-0.79), and 5.16 (95% CI 2.59-3.46), respectively. This systematic review revealed that there were major differences in the definitions of CT findings, and that the integration of CT findings might not be adequate for predicting short-term mortality in ARDS. Standardisation of CT findings and accumulation of further studies by CT with unified standards are warranted.

INTRODUCTION: A subgroup analysis of the CAPACITY and ASCEND trials showed that pirfenidone use beyond disease progression reduced the risk of subsequent forced vital capacity (FVC) decline and death. Our study aimed to compare the efficacy and safety of nintedanib with or without pirfenidone for patients with idiopathic pulmonary fibrosis (IPF) who experienced disease progression during previous pirfenidone therapy. METHODS: In this randomized, open-label, selection design phase II trial, patients with IPF and a ≥5% relative decline in FVC within 6âmonths of the pirfenidone administration period were randomly assigned to nintedanib (switch group) or nintedanib plus pirfenidone (combination group). The primary endpoint was the incidence of a ≥5% relative decline in FVC or death during the first 6âmonths. RESULTS: Only 7 patients were enrolled (4 in the switch group and 3 in the combination group). Although the switch group continued with nintedanib for 1âyear or more, 2 patients (66.7%) in the combination group discontinued nintedanib within 6âmonths due to severe adverse events. Given the slow case registration and safety concerns in the combination group, the trial was terminated without extending the registration. The incidence of a ≥5% relative decline in FVC during the first 6âmonths was 50.0% in the switch group and 66.7% in the combination group. There were no deaths during the observation period. CONCLUSIONS: Clinical trials verifying the use of pirfenidone after disease progression in IPF may be difficult to enroll patients. Definitive conclusions on both safety and efficacy cannot be drawn from the results of this study alone.

A 61-year-old patient with cystic bronchiectasis and bronchial artery hyperplasia in the left lung was diagnosed with polymyositis-related interstitial lung disease. After nine months of immunosuppressive therapy, he developed unilateral autoimmune pulmonary alveolar proteinosis (APAP) in the right lung with respiratory failure. After bronchial artery embolization to prevent massive hemoptysis, whole-lung lavage was performed using veno-venous extracorporeal membrane oxygenation. His respiratory condition improved, and he was discharged from the hospital with supplemental oxygen. Three reported cases of APAP with polymyositis-related interstitial lung disease, including the present case, were all positive for anti-glycyl tRNA synthetase antibody and were under immunosuppressive treatment.

BACKGROUND: This study aimed to investigate the clinical characteristics and prognosis of patients with pleuroparenchymal fibroelastosis (PPFE) and pulmonary hypertension (PH). METHODS: We retrospectively analyzed the data of patients who were diagnosed with PPFE and underwent transthoracic echocardiography (TTE) for the evaluation of their right heart systems within 3 months of their first visit between 2011 and 2018. Patients were divided into the PH and non-PH groups based on their peak tricuspid regurgitation velocity (TRV) on TTE (cutoff, 2.8 m/s). The clinical characteristics of PH and association between PH and survival among patients with PPFE were investigated. RESULTS: In total, 83 patients were enrolled. Sixteen (19.3%) patients were included in the PH group. The PH group had a lower body mass index, percent predicted forced vital capacity (FVC), 6-min walk distance, and partial pressure of arterial oxygen than the non-PH group. There was no significant difference in the presence of usual interstitial pneumonia patterns in the lower lobes between the two groups. The survival period was significantly shorter in the PH group than in the non-PH group (median survival 16.3 versus 50.2 months, log-rank p < 0.001). The multivariate Cox proportional hazard model showed that male sex (hazard ratio [HR] = 4.83, p < 0.001), Krebs von den Lungen-6 (KL-6) > 550 U/mL (HR = 3.48, p = 0.005), %FVC < 50% (HR = 3.04, p = 0.028), and peak TRV > 2.8 m/s (HR = 3.26, p = 0.038) were independently associated with poor survival. CONCLUSIONS: PH was not rare in patients with PPFE. Male sex, increased KL-6, lower FVC, and PH were independently associated with poor survival in patients with PPFE.

BACKGROUND: Surgical lung biopsy (SLB) is performed in patients with acute respiratory distress syndrome (ARDS); however, its clinical utility remains unclear. OBJECTIVES: We categorized the pathological diagnoses and investigated the predictive value for short-term mortality. METHOD: Three electronic databases (MEDLINE, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov) were searched for the included studies. The QUADAS-2 was used to evaluate the risk of bias and its applicability. The types and populations of pathological diagnoses were investigated. The pooled sensitivity, positive likelihood ratio (LR+), negative likelihood ratio (LR-), and diagnostic odds ratio (DOR) were estimated at a fixed specificity. Hierarchical summary receiver operating characteristic curves were drawn. RESULTS: A total of 16 studies that enrolled 758 patients were included. The pathological diagnoses were as follows: diffuse alveolar damage (DAD) 29.9%; infection 24.7%; interstitial lung disease 17.2%; malignancy 3.6%; cardiovascular disease 3.6%; drug toxicity 2.3%; connective tissue disease 2.2%; allergic disease 1.1%; and nonspecific diagnosis 15.4%. To predict short-term mortality, 13 studies that enrolled 613 patients used DAD as an index test and recorded a mortality rate of 56.9% (349 of 613 patients). A total of 3 studies that used index tests other than DAD were excluded. The pooled sensitivity, fixed specificity, LR+, LR-, and DOR were 0.46 (95% confidence interval [CI]: 0.29-0.56), 0.69, 1.48 (95% CI: 0.92-1.81), 0.78 (95% CI: 0.63-1.03), and 1.90 (95% CI: 0.89-2.86), respectively. CONCLUSIONS: SLB is unlikely to provide a specific diagnosis and should not be recommended for confirming DAD or predicting ARDS prognosis.

BACKGROUND: The serum Krebs von den Lungen-6 (KL-6) level is a predictive factor for acute respiratory distress syndrome (ARDS). The development of ARDS has been reported in patients with coronavirus disease 2019 (COVID-19). This study aimed to determine whether serum KL-6 levels are associated with mortality and severity in patients with COVID-19. METHODS: Among 361 Japanese patients with COVID-19 who were hospitalized at Kanagawa Cardiovascular and Respiratory Center between February 2020 and December 2020, 356 patients with data on serum KL-6 levels were enrolled and their medical records were retrospectively analyzed. RESULTS: A negative correlation was observed between KL-6 levels and the ratio of the arterial partial pressure of oxygen to the fraction of inspired oxygen on admission. The KL-6 levels on admission and the maximal KL-6 levels were higher in patients with severe disease (n = 60) than in those with nonsevere disease (n = 296). Furthermore, the maximal KL-6 levels were higher in nonsurvivors (n = 6) than in survivors (n = 350). In nonsurvivors, the KL-6 levels increased as the disease progressed. The optimal cutoff value of the maximal KL-6 level for discriminating between survivors and nonsurvivors was 684 U/mL, with a sensitivity of 83.3%, a specificity of 90.5%, and an area under the curve of 0.89. CONCLUSIONS: The serum KL-6 level was associated with disease severity. Patients with KL-6 levels ≥684 U/mL had a significantly poorer outcome than those with KL-6 levels <684 U/mL.

INTRODUCTION: Although several reports on the risk factors for severe disease of COVID-19 already exist, reports on effective early indicators are still limited, especially from Japan. This study was conducted to clarify the patient's characteristics whose disease progressed to severe status. METHODS: The medical records of all consecutive 300 Japanese patients hospitalized at our institution between February and November 2020 were retrospectively reviewed. The clinical characteristics were evaluated to compare between mild (no oxygen needed), moderate (oxygen needs of 1-4 L/min), and severe diseases (oxygen needs of 5 L/min or more). RESULTS: The median age was 68 years old, with 123 (41.0%) males and 177 (59.0%) females. Of these, 199 patients (66.3%), 55 patients (18.3%), 46 patients (15.3%) patients were in the mild disease, moderate disease, severe disease groups, respectively. Patients with severe disease were more likely to be older, have more comorbidities, and tended to have higher body mass index. In laboratory data, lymphocyte count, levels of C-reactive protein (CRP), LDH, and AST on admission were significantly associated with the severity. In multivariate analysis, age and CRP were the independent risk factors for severe disease (OR = 1.050, 1.130, respectively). The optimal cut-off value for age was 74 years old and that for CRP was 3.15 mg/dL. CONCLUSIONS: Age and CRP were independently associated with disease severity of COVID-19 in multivariate analysis. Additionally, the numbers of underlying disease, lymphocyte count, and inflammatory markers such as LDH and D-dimer may also be related to disease severity.

BACKGROUND: Pleuroparenchymal fibroelastosis (PPFE) is a unique clinical, radiologic, and histopathologic entity for which several potential etiologies have been reported recently. However, there has been no comprehensive study of secondary PPFE. OBJECTIVE: Assessment of the clinical characteristics, outcomes, and prognostic factors of secondary and idiopathic PPFE. METHODS: We retrospectively reviewed the medical records of consecutive PPFE patients between January 1999 and December 2018. We identified 132 idiopathic PPFE patients and 32 secondary PPFE patients. RESULTS: The incidence of interstitial lung disease (ILD) pattern different from the usual interstitial pneumonia (UIP) pattern in the lower lobes was higher in secondary PPFE patients (38.5%) than in idiopathic PPFE patients (61.5%, p = 0.02). The idiopathic and secondary PPFE groups did not differ significantly in terms of laboratory data, respiratory complications, and survival (median: 5.0 years vs. 4.1 years, p = 0.95). The presence of UIP pattern was independently associated with increased mortality in multivariate analyses in idiopathic PPFE patients, but not in secondary PPFE patients. CONCLUSIONS: The frequency and prognostic impact of UIP-pattern ILD differed between idiopathic and secondary PPFE patients. Lung transplantation should be considered in secondary PPFE patients with low diffusing capacity of the lungs for carbon monoxide (DLCO) regardless of lower-lobe ILD pattern.
RESUMO
A 57-year-old man visited a referral physician due to abnormal chest shadows. Transbronchial lung biopsy (TBLB) failed to diagnose his condition. As antibiotics and systemic steroids did not improve the condition, he was referred to our hospital. A second TBLB in our hospital also failed to diagnose the disease. Transbronchial lung cryobiopsy (TBLC) was performed using radial endobronchial ultrasound with guide sheath (EBUS-GS), and the patient was diagnosed with lipoid pneumonia. Right upper lobe resection was performed, and lipoid pneumonia was confirmed from the surgical specimen. We report a case of lipoid pneumonia diagnosed by EBUS-GS TBLC.

The aim of this study was to investigate the prevalence and prognostic value of coronary artery disease (CAD) and heart failure (HF) in patients with idiopathic pulmonary fibrosis (IPF). Thirteen hundred and fifty-eight patients with interstitial lung disease [851 (62%) males, mean age: 68 ± 10 years] were retrospectively analyzed. CAD was defined as (1) the presence of a clinical diagnosis of angina pectoris, (2) clinical diagnosis of a myocardial infarction, and (3) coronary angiography showing ≥ 1 vessel with a stenosis of > 75%. The definition of HF was made according to the modified Framingham criteria. Compared to the non-IPF group (n = 790), the IPF group (n = 568) had a significantly higher prevalence of CAD (9.3% vs. 4.4%, p < 0.001) and HF (8.2% vs. 3.7%, p < 0.001). During a median follow-up of 1.6 years, 152 deaths were identified. The patients with HF had a significantly worse prognosis than those without HF both in the non-IPF group and IPF group (both p < 0.05). However, the prognosis did not significantly differ between the patients with CAD and those without CAD both in the non-IPF group and IPF group. The presence of HF was an independent predictor of death in the IPF [hazard ratio (HR) 3.67, 95% confidence interval (CI) 1.57-8.56, p = 0.0025] and non-IPF (HR 5.07, 95% CI 1.44-17.86, p = 0.011) patients. The prevalence of CAD and HF was significantly higher in IPF than non-IPF patients. In addition, the presence of HF was a significant prognostic factor for both IPF and non-IPF patients. These results indicated that the importance of HF as a comorbidity for patients with ILD.

BACKGROUND: In the phase III trial of nintedanib, only 10.8% of participants were aged ≥75 years. Here, we aimed to evaluate the tolerability and safety of nintedanib in elderly patients with idiopathic pulmonary fibrosis (IPF). METHODS: In total, 71 consecutive patients with (1) IPF, (2) age ≥75 years, and (3) newly prescribed nintedanib from September 2015 to April 2018 (elderly group) were retrospectively reviewed. Patient characteristics, treatment status, and adverse events (AEs) were compared between the elderly group and 126 patients with IPF, aged <75 years, with newly prescribed nintedanib during the same period (non-elderly group). RESULTS: In the elderly group, 32 patients (46.4%) discontinued nintedanib within 6 months. Body size was significantly smaller, the incidence rates of anorexia and nausea were significantly higher, and early termination within 6 months were more common in the elderly than in the non-elderly group. In elderly patients, a univariate logistic regression analysis showed that body mass index (BMI) and percentage forced vital capacity (FVC) were risk factors for early termination (p = 0.02 and 0.03, respectively). A low initial nintedanib dose did not reduce the incidence of AEs and early termination rate in the elderly group. CONCLUSIONS: In elderly patients with IPF, the incidence of early nintedanib termination was higher, and anorexia and nausea were common AEs compared with those in non-elderly IPF patients. Treatment was frequently discontinued in elderly patients with low BMI and FVC, and chest physicians should be aware that nintedanib therapy may result in early termination in these patients.

BACKGROUND: Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by deteriorated exocrine gland function with associated lymphocytic infiltration. However, there are few pathological studies on bronchial glands in SS. In this study, we aimed to clarify pathological features of bronchial glands in SS. METHODS: We retrospectively evaluated infiltration of lymphocytes in the bronchial glands incidentally collected by transbronchial lung cryobiopsy (TBLC), which were performed for the diagnosis of diffuse lung diseases. The degrees of lymphocyte infiltration in the bronchial glands were classified into four grades (grade 0-3). We compared the degrees of infiltration of SS with those of other diffuse lung diseases. RESULTS: TBLC for diagnosis of diffuse lung diseases were performed on 432 cases during the study period. The samples of 50 cases included bronchial glands. Of those, 20 cases were excluded due to insufficient size or influence of therapy. The remaining 30 cases included 17 of idiopathic interstitial pneumonias, 5 of chronic hypersensitivity pneumonia, 6 of connective tissue disease (SS; n = 4, systemic sclerosis; n = 1, dermatomyositis; n = 1) and 2 of other diseases. In SS, infiltration of lymphocytes was observed in all cases; grade 1 in one, grade 2 in one, and grade 3 in two cases. In contrast, 11 of 26 in other diseases showed no lymphocytes infiltration, with the remaining 15 of grade 1 infiltration. Grade 2 or more infiltration were found only in SS but not in other diseases. CONCLUSION: Our results suggested that high-grade lymphocytic infiltration of bronchial glands is a distinct characteristics in SS.

INTRODUCTION: Bronchial thermoplasty (BT) improves asthma-related quality of life and decreases the number of asthma exacerbations. However, the effectiveness of BT in the treatment of severe asthma with smoking history is unclear because previous studies have excluded patients with smoking history of more than 10 pack-years. OBJECTIVE: The aim of the study was to clarify the effectiveness and safety of BT for severe asthma with smoking history. METHODS: We retrospectively reviewed patients who received BT and compared its effectiveness and safety with and without smoking history. RESULTS: Seven patients were assigned to the smoking group and 9 to the nonsmoking group. Before BT, despite Global Initiative for Asthma step 4 or 5 treatment including oral corticosteroids (OCS) or monoclonal antibody drugs, most patients in both groups had asthma-related symptoms every day (85.7 vs. 77.8%; p = 0.475) and frequent asthma exacerbations. After BT, in the smoking group, 3 patients could discontinue or reduce OCS and all 3 patients treated with monoclonal antibody drugs could discontinue them. In the smoking group, 6 patients (85.7%) experienced a reduction in the rate of symptoms, of which 3 patients (42.9%) had a disappearance of symptoms, similar to the nonsmoking group. BT was effective in 5 patients (83.3%) in the smoking group and 6 patients (75.0%) in the nonsmoking group. There were no severe complications. CONCLUSIONS: BT was found to be effective and safe for treatment of severe asthma with smoking history. Our results suggest that BT may be a therapeutic option for asthma-chronic obstructive pulmonary disease overlap.
