    BACKGROUND: Nontuberculous mycobacteria (NTM), particularly the Mycobacterium avium complex (MAC), is becoming a global health burden with increasing incidence worldwide. Previous studies have linked pulmonary function impairment with increased mortality in NTM lung disease, suggesting that lung volume may be a critical predictor of mortality. The objective of this study was to assess the prognostic value of lung field area (LFA) in predicting all-cause mortality among patients with MAC lung disease. METHODS: We conducted a longitudinal cohort study of 232 patients diagnosed with MAC lung disease at NHO Fukuoka National Hospital from April 1996 to December 2021. Quantitative CT image analysis was performed to measure LFA. Statistical analysis included Kaplan-Meier curves and Cox proportional hazards models to estimate mortality risk, adjusting for demographic and clinical variables. RESULTS: Patients with lower LFAs had significantly higher mortality rates (P < 0.01 for a trend), with a multivariable-adjusted hazard ratio of 5.90 (95% CI, 1.85-18.76) for the lowest tertile as compared to the highest. The predicting ability of mean LFA for all-cause death was superior to that of cavitary lesions assessed by low-attenuation areas (LAA), with area under the curve values of 0.77 for LFA versus 0.53 for LAA (P < 0.01). CONCLUSION: Decreased LFA is an independent risk factor for mortality in patients with MAC lung disease, offering better prognostic utility than traditional markers of disease severity such as cavity lesions. These findings highlight the potential for LFA to guide clinical management and risk stratification in MAC lung disease.

    Abstract <p>Background Low skeletal muscle mass has been reported to associated with poor prognosis in patients with idiopathic pulmonary fibrosis (IPF). However, such associations have scarcely reported in idiopathic interstitial pneumonias (IIPs) other than IPF. Quantification of muscle mass obtained from chest computed tomography (CT) is used as a simple screening tool for sarcopenia in patients with respiratory diseases. However, the optimal thoracic site for muscle mass quantification is controversial. Moreover, there have been no reports investigating the association between muscle mass and acute exacerbations. This study aimed to evaluate optimal site for muscle mass quantification in chest CT to predict survival and acute exacerbation in IPF and non-IPF idiopathic interstitial pneumonias (IIPs).Methods This study included 528 patients diagnosed with IIP at 29 facilities between September 1, 2013, and April 30, 2016, following multidisciplinary discussions with prospective follow-up over a 5-year period. The cohort was divided into two groups: those with IPF and those with non-IPF IIPs. Skeletal muscle mass was quantified using the erector spinae muscle index (ESMI) and pectoralis muscle index (PMI) based on chest computed tomography (CT) at the time of enrollment. Associations between these indices at baseline and both survival and acute exacerbation were analyzed.Results In both IPF and non-IPF cohorts, Cox regression analysis revealed that patients with low ESMI had a poorer prognosis compared to those with normal ESMI, even after adjusting for age, sex, %FVC, and smoking exposure level (HR 0.62, p = 0.013; HR 0.46, p = 0.009, respectively). In contrast, no significant relationship was identified between PMI and survival. Multivariable Cox regression analysis confirmed that ESMI was an independent predictor of survival in both IPF and non-IPF patients. Additionally, acute exacerbations occurred more frequently in the low ESMI group, particularly among non-IPF patients.Conclusions The ESMI obtained from chest CT is associated with survival in not only in IPF patients but also in the non-IPF patients. The ESMI also associate with acute exacerbations in non-IPF patients.</p>

    The Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification, based on percent predicted forced expiratory volume in 1 s (ppFEV1), has been widely adopted for assessment of chronic obstructive pulmonary disease (COPD) severity. However, the STaging of Airflow obstruction by Ratio (STAR) system, based on the ratio of FEV1 to forced vital capacity, was recently proposed as an alternative classification. This study aimed to compare the prognostic performance of the GOLD and STAR classifications for prediction of mortality and exacerbation risk in individuals with COPD. This 5-year prospective, multicenter cohort study enrolled 370 individuals with COPD at 29 medical centers. All-cause mortality risk across GOLD and STAR stages was evaluated with Kaplan-Meier curves and Cox proportional hazards models. The risk of moderate to severe COPD exacerbations across GOLD and STAR stages was examined with cumulative incidence function (CIF) curves and Fine and Gray models. Both classification systems showed a significant association with mortality and exacerbation risk (P < 0.01 for trend). The GOLD classification provided a better separation of Kaplan-Meier and CIF curves for advanced stages, whereas the STAR classification showed a clearer distinction between stages I and II. These associations remained consistent after multivariable adjustments. The GOLD classification was superior for prediction of prognosis in advanced COPD, whereas the STAR classification provided better differentiation in early-stage disease. These findings highlight the complementary roles of the GOLD and STAR classifications in assessment of COPD severity.

    BACKGROUND: Osimertinib is a standard treatment for non-small cell lung cancer (NSCLC) positive for EGFR activating mutations. Although renal dysfunction associated with osimertinib treatment is reported to be rare, detailed information on this adverse effect is needed because cytotoxic drugs such as pemetrexed are also widely administered for NSCLC but cannot be used in individuals with renal dysfunction. METHODS: We retrospectively collected clinical data including the serum creatinine concentration and estimated glomerular filtration rate (eGFR) during osimertinib treatment for 130 NSCLC patients. RESULTS: Serum creatinine and eGFR worsened gradually during osimertinib treatment, with the median value of creatinine at the point of greatest deterioration differing significantly from that at baseline (0.93 versus 0.72 mg/dL, P < 0.01). Seventy patients (54 %) experienced worsening of the CTCAE grade for creatinine increased, with the frequency of patients with grade 1 or 2 being increased significantly (P < 0.01) at the point of greatest deterioration relative to baseline (grade 1, 46.9 % versus 14.6 %; grade 2, 14.6 % versus 0.8 %, respectively). A higher serum creatinine level at baseline was a significant risk factor for worsening of the CTCAE grade (odds ratio of 1.66, P < 0.001). The median serum creatinine and eGFR at 4 weeks after osimertinib discontinuation had improved to levels similar to those for baseline. CONCLUSIONS: Renal dysfunction occurred frequently during osimertinib treatment but was ameliorated after drug discontinuation, suggesting that, although renal function should be carefully monitored, its impairment is not likely to affect subsequent chemotherapy in most patients.

    BACKGROUND AND OBJECTIVE: Lung function abnormality of obstructive sleep apnea (OSA) has not been explored well. Preserved ratio impaired spirometry (PRISm) is known for its association with obesity and cardiovascular morbidity, which are also characteristic features of OSA. This study aims to investigate whether the prevalence of PRISm increases according to apnea-hypopnea index levels among subjects with OSA. METHODS: Conducted as an observational cross-sectional study, the study included 372 patients ≥40 years of age with definitive diagnoses of OSA and pulmonary function assessment from 2000 to 2004. Study subjects were classified based on OSA severity (mild/moderate versus severe). The prevalence of PRISm was estimated and compared between mild/moderate and severe OSA groups. RESULTS: The prevalence of PRISm was 9.4 % in study subjects, with a higher prevalence in the severe OSA group than the mild/moderate group (12.9 % and 6.2 %, respectively, P = 0.04). The positive association between severe OSA and PRISm remained robust after multivariable adjustment for age, gender, and obesity (multivariable-adjusted odds ratio 2.29 (95 % confidence intervals 1.08-4.86), P = 0.03). CONCLUSION: Severe OSA is an independent risk factor for PRISm, highlighting the need for comprehensive management of OSA that addresses the potential risk of PRISm.

    BACKGROUND: Hay fever (HF) presents with various symptoms, including allergic conjunctivitis and rhinitis, and requires cross-organ treatment. This study assessed the impact of the coronavirus disease 2019 (COVID-19) pandemic on HF treatment trends. METHODS: This retrospective cohort study utilized data from the JMDC database collected between January 2018 and May 2021. Patients with HF were identified based on the relevant International Classification of Diseases 10th Revision diagnosis codes and the prescription of HF-related medications. The treatment approaches were compared during the cedar and cypress pollen allergy season (January to May in Japan) before and during the COVID-19 pandemic (2018 and 2019, and 2020 and 2021, respectively). RESULTS: This study included 2,598,178 patients with HF. The numbers of prescribed HF-related claims in 2018, 2019, 2020, and 2021 were 3,332,854, 3,534,198, 2,774,380, and 2,786,681 times, respectively. Oral second-generation antihistamine prescriptions decreased by >10% from 2019 to 2020, with a <10% change in the subsequent year. Anti-allergic eye drop prescriptions also decreased by >10% from 2019 to 2020 but increased by >10% from 2020 to 2021. Compared with 2018, 2019, and 2020, the number of claims in the rhinitis symptoms dominant group was significantly decreased in 2021 (p < 0.001, all). In contrast, the number of claims in the eye symptoms dominant group and the rhinitis and eye symptoms dominant group increased in 2021 compared with that in 2018, 2019, and 2020 (p < 0.001, all). CONCLUSION: Changes in HF treatment and related outcomes could be attributed to lifestyle modifications resulting from the COVID-19 pandemic. Measures, such as limiting outdoor activities and adopting mask-wearing practices may have influenced HF symptoms, preventive behaviors, and the overall approach to treating HF.

    This report presents the case of a 42-year-old Japanese woman with recurrent hormone receptor-positive breast cancer who developed eosinophilic pneumonia (EP) during treatment with abemaciclib combined with endocrine therapy. Seven years after a radical surgery and definite diagnosis of Stage I breast cancer, her cancer recurred with metastases to multiple organs. Initially treated with abemaciclib plus letrozole and goserelin for 3 months, she developed EP, which improved after the discontinuation of anti-cancer treatment and the administration of prednisolone. However, EP occurred again upon the reintroduction of endocrine therapy (i.e., letrozole and goserelin). It improved gradually with the suspension of endocrine therapy and the re-administration of prednisolone. This case underscores the need for further research into the prevention and management of EP in patients receiving abemaciclib with endocrine therapy for advanced breast cancer.

    The increasing prevalence of Mycobacterium avium complex (MAC) pulmonary disease poses a significant therapeutic challenge, particularly due to the limited efficacy and systemic toxicity associated with conventional guideline-based therapy. Amikacin liposome inhalation suspension (ALIS) has been developed, yet its real-world application remains underreported. This retrospective analysis, conducted from March 2021 to February 2024, examined ALIS's clinical use in patients aged 20 years or older with refractory MAC pulmonary disease at our institution. The primary objective of this study is to describe the patient characteristics and clinical trajectories associated with the initiation of ALIS therapy in real-world settings for individuals diagnosed with MAC pulmonary disease. Of 11 patients initiated on ALIS, one was excluded due to financial constraints impacting continuation. The analysis proceeded with the remaining 10 subjects. The mean age of participants was 70.2 years, with a predominance of female patients (n = 7, 70%) and a higher incidence of M. avium infections (n = 6, 60%). Forty percent of the cohort (n = 4) had a history of ethambutol-induced optic neuritis leading to the cessation of the drug. The average interval from the initiation of guideline-based therapy to the start of ALIS was 8.5 ± 6.9 years (mean ± standard deviation). The majority (80%) presented with positive Gaffky scores at ALIS initiation, and a significant proportion exhibited resistance to clarithromycin and ethambutol. Comorbid conditions, including diabetes and previous cancer, were noted. The study also observed elevated anti-MAC antibody levels. Treatment duration varied, with fatigue leading to discontinuation in two cases. Treatment-emergent adverse events were documented in individual patients, each presenting with grade 1 severity: hemoptysis (n = 1, 10%), elevated creatinine levels (n = 1, 10%), and dysphonia (n = 2, 20%) were observed, respectively. Correlation analysis revealed a significant inverse relationship between body mass index (BMI) and ALIS discontinuation due to fatigue, and a positive correlation between Gaffky scores and C-reactive protein (CRP) levels. These results underscore the potential benefits and limitations of ALIS, suggesting that timely intervention and comprehensive healthcare support are crucial for optimal outcomes in the treatment of advanced MAC pulmonary disease.

    Here, we report a case of an 87-year-old female patient with rheumatoid arthritis (RA) treated with methotrexate (MTX) and golimumab who developed severe pneumocystis pneumonia (PCP), also known as Pneumocystis jirovecii pneumonia. The patient presented with chief complaints of dyspnea on exertion, dry cough, and fatigue. A high-resolution chest CT scan revealed diffuse, unevenly distributed ground-glass opacities throughout both lungs. The patient was clinically diagnosed with PCP based on the clinical settings, imaging, and a high level of serum β-D-glucan. While the patient required high-flow oxygen therapy, low-dose trimethoprim/sulfamethoxazole and corticosteroid therapy improved her condition, and the patient was discharged on day 25. Although to our knowledge no case report has been published regarding PCP in patients with RA treated with golimumab, this case emphasizes the importance of attention to opportunistic infections in elderly patients receiving immunosuppressive therapy. MTX use alongside tumor necrosis factor inhibitors like golimumab may increase the risk of serious infections such as PCP. The case underscores the necessity of prophylactic measures and early intervention for PCP, highlighting the delicate balance between immunosuppression benefits and infection risks in RA management.

Despite the absence of any smoking or dust exposure history, multiple cystic lesions were apparent in both lungs on her CT scan. We suspected Sjögren's syndrome-associated lymphocytic interstitial pneumonia (LIP) due to her additional symptoms of dry mouth and eyes. Her respiratory function test showed a restrictive disorder with a forced vital capacity (FVC) of 1.23 L (70.3 % predicted), forced expiratory volume in 1 s (FEV1) of 0.88 L, and FEV1/FVC of 71.5 %. The flow-volume curve showed a downward convex, suggesting peripheral airway obstruction. We initiated a daily inhalation treatment regimen comprising vilanterol 25 μg and fluticasone furoate 200 μg. One month later, at the follow-up visit, the clinical diagnosis of Sjögren's syndrome with LIP was made by positive SS-A and SS-B antibodies in the initial blood work, a Saxon test that confirmed decreased salivary secretion, and a confirmed diagnosis of dry eyes by her ophthalmologist. We noted improvement in FVC of 1.45 L (+17.8 %) and FEV1 to 0.99 L (+12.5 %) in the subsequent respiratory function test, along with alleviation of her symptoms. The present case represents the first report of LIP treated exclusively with inhaled corticosteroids and bronchodilators, highlighting a potential therapeutic approach, particularly for elderly patients vulnerable to immunosuppressive therapies.

    We report a case of a female patient in her 50s, previously diagnosed with follicular lymphoma (now in complete remission), who was admitted to our hospital due to antibiotic-resistant pneumonia lasting a month. The patient had contracted coronavirus disease 2019 (COVID-19) pneumonia a year earlier and exhibited persistent hypogammaglobulinemia. Chest CT scans revealed wondering ground-glass opacities and consolidations initially suggestive of cryptogenic organizing pneumonia (COP). Despite repeatedly negative nasopharyngeal SARS-CoV-2 tests, the virus was detected in the bronchoalveolar lavage fluid (BALF) using the BioFire FilmArray Respiratory Panel 2.1. She was subsequently diagnosed with COVID-19 pneumonia and responded well to treatment with remdesivir (RDV) and intravenous immunoglobulin. The SARS-CoV-2 variant in the BALF was suspected as the Omicron variant (XBB.1.16), prevalent in the area at the admission, indicating a re-infection rather than a recurrence. This case underscores the protracted nature of COVID-19 pneumonia in immunocompromised patients and the risks of false negatives in nasopharyngeal SARS-CoV-2 tests. Direct SARS-CoV-2 measurement from BALF can be crucial in such cases. A COP diagnosis based solely on imaging and administering corticosteroids without antiviral treatment might exacerbate the situation by reactivating SARS-CoV-2. Given the current pandemic, clinicians should be aware of the potential for persistent or recurrent COVID-19, particularly in immunocompromised patients.

    We report a 72-year-old female who presented to our hospital with a worsening cough and dyspnea that had emerged a week earlier following the accidental inhalation of a significant quantity of spray-type imiprothrin (a synthetic pyrethroid)-based insecticide in her bathroom. She exhibited acute respiratory failure necessitating 4 L/minute of nasal oxygen at maximum. Chest CT images showed diffuse centrilobular ground-glass opacities with mosaic attenuation and consolidation areas in the lower lobes of both lungs. The patient was diagnosed with acute pneumonitis due to insecticide inhalation, and her symptoms improved following methylprednisolone pulse and alpha-tocopherol therapy. Generally, the accidental inhalation of aerosolized pyrethroids does not induce significant respiratory symptoms, and case reports on pulmonary toxicity related to pyrethroid inhalation are scarce. This case report underscores the need to include inhaled pyrethroid insecticides in the differential diagnosis of patients with acute pneumonitis and suggests that methylprednisolone and alpha-tocopherol therapy can be beneficial for treating this condition.

    We report a case of a 68-year-old woman who was being treated for bronchial asthma and developed allergic bronchopulmonary aspergillosis (ABPA) that was unresponsive to benralizumab therapy but went into remission with dupilumab therapy. The patient presented with an exacerbation of dry cough and was diagnosed with ABPA based on new diagnostic criteria. Despite the attempted therapeutic intervention, the patient declined to use systemic corticosteroids due to concerns about potential side effects. Subsequently, itraconazole and benralizumab were administered, with temporary relief before relapse. Given the patient's refusal to continue itraconazole and benralizumab, dupilumab was administered as an alternative therapy, which resulted in significant improvement of both symptoms and imaging. Although the use of biological agents for ABPA lacks clear evidence, our results suggest that dupilumab may provide an effective therapeutic strategy.

    We report a case of a 74-year-old male who exhibited bilateral lower extremity edema over three days. Examination revealed no signs of heart, renal, or hepatic failure, and hypothyroidism was also ruled out. An outpatient regimen of 40 mg furosemide was initiated. At a 12-day follow-up, although the edema had improved, the patient had developed pain in both lower limbs, especially ankles, accompanied by numerous petechiae and erythemas, some of which had formed papules. Skin biopsy of the rash displayed leukocytoclastic vasculitis with immunoglobulin A (IgA) deposition within the vascular walls, leading to a diagnosis of IgA vasculitis. Given the rarity of IgA vasculitis in elderly patients and the broad spectrum of potential diagnoses related to bilateral lower extremity edema in this population, IgA vasculitis can be easily overlooked. While this case did not present with glomerulonephritis, regular renal function monitoring is recommended due to the prognostic implications of renal involvement in adult-onset IgA vasculitis.

    An 82-year-old man had been diagnosed with asthma. He experienced repeated exacerbations requiring treatment with a systemic corticosteroid despite being treated with medications including high-dose fluticasone furoate/umeclidinium/vilanterol, montelukast sodium, and theophylline; treatment with mepolizumab was then initiated. The patient had been free from exacerbations for 15 months; however, he suffered from post-obstructive pneumonia and atelectasis secondary to mucoid impaction in the right middle lobe of the lung, accompanied by a productive cough, wheezing, dyspnea, and right chest pain. In addition to the development of mucus plugs, the levels of serum IgE specific to Aspergillus spp. became positive; a definite diagnosis of allergic bronchopulmonary aspergillosis (ABPA) was established. The patient underwent treatment with tezepelumab. Over 3 months, the mucus plugs and pulmonary opacities diminished gradually in parallel with the improvement in the control of asthmatic symptoms. Tezepelumab might provide a novel steroid-sparing strategy for the management of ABPA, although further studies are required.

    BACKGROUND: Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) patients experience exacerbations more frequently than those with asthma or COPD alone. Since low diffusing capacity of the lung for carbon monoxide (DLCO) is known as a strong risk factor for severe exacerbation in COPD, DLCO or a transfer coefficient of the lung for carbon monoxide (KCO) is speculated to also be associated with the risk of exacerbations in ACO. METHODS: This study was conducted as an observational cohort survey at the National Hospital Organization Fukuoka National Hospital. DLCO and KCO were measured in 94 patients aged ≥ 40 years with a confirmed diagnosis of ACO. Multivariable-adjusted hazard ratios (HRs) for the exacerbation-free rate over one year were estimated and compared across the levels of DLCO and KCO. RESULTS: Within one year, 33.3% of the cohort experienced exacerbations. After adjustment for potential confounders, low KCO (< 80% per predicted) was positively associated with the incidence of exacerbation (multivariable-adjusted HR = 3.71 (95% confidence interval 1.32-10.4)). The association between low DLCO (< 80% per predicted) and exacerbations showed similar trends, although it failed to reach statistical significance (multivariable-adjusted HR = 1.31 (95% confidence interval 0.55-3.11)). CONCLUSIONS: Low KCO was a significant risk factor for exacerbations among patients with ACO. Clinicians should be aware that ACO patients with impaired KCO are at increased risk of exacerbations and that careful management in such a population is mandatory.

    Purpose: Similar to chronic obstructive pulmonary disease (COPD), the diffusing capacity of the lung (DLCO) might be decreased and associated with poor prognosis in preserved ratio impaired spirometry (PRISm), a clinical entity as a prodromal phase of COPD. The aims of the present study were to evaluate the distributions of DLCO and to assess the association between DLCO and mortality among subjects with PRISm. Patients and Methods: We conducted an observational cohort study at the National Hospital Organization Fukuoka National Hospital. We classified the 899 patients ≥ 40 years of age with an assessment of DLCO into five groups based on spirometry: preserved spirometry, PRISm, mild COPD, moderate COPD, and severe/very severe COPD. The prevalence of low DLCO (< 80% per predicted) was compared among the five groups. Using PRISm patients with follow-up data, we further investigated the association of low DLCO with all-cause mortality. Results: The prevalence of low DLCO in the PRISm group (58.8%) was significantly higher than that in the preserved-spirometry group (21.8%), the mild-COPD group (23.5%), and the moderate-COPD group (36.0%) (all P < 0.01), and it was comparable to that in the severe/very severe-COPD group (63.2%). The results remained unchanged after adjusting for potential confounders. Among the PRISm subjects, the overall survival rate was significantly lower in the low-DLCO group than in the preserved-DLCO group (P < 0.01). The multivariable-adjusted hazard ratio (HR) for all-cause mortality was significantly higher in the low-DLCO group than in the preserved-DLCO group (HR = 10.10 (95% confidence interval 2.33-43.89)). Conclusion: Diffusing capacity was more impaired in PRISm subjects than in those with preserved spirometry or mild to moderate COPD. Regarding PRISm, low DLCO was a significant risk factor for all-cause mortality. Clinicians should assess DLCO in the management of PRISm to predict the future risk of overall death.

  • 閉塞性肺疾患を有する患者と有しない患者由来の末梢気道細胞を用いた感染防御免疫 応答の解析

    clinical research

      More details

    Authorship:Coinvestigator(s) 

    気道のウイルス感染や細菌感染は気管支喘息やCOPDなどの閉塞性肺疾患の急性増悪の主たる原因であり、急性増悪を繰り返すことによりそれらの疾患の更なる病態悪化を招くことが知られている。ただし閉塞性肺疾患患者の気道局所における感染反復および急性増悪発症の機序は明らかでない。本研究では閉塞性肺疾患(気管支喘息あるいはCOPD)を有する患者と有しない患者由来の末梢気道細胞を採取し、培養条件下でウイルスや細菌に対する感染防御免疫応答の解析を行う。日常臨床として施行される気管支鏡検査の際に、少量の気道上皮細胞を採取培養し、ウイルスや細菌感染による免疫応答の変化を細胞レベルで比較検討する。

  • 閉塞性肺疾患を有する患者と有しない患者由来の唾液・舌苔・気管支被覆液を用いたマイクロバイオームの比較研究

    clinical research

      More details

    Authorship:Coinvestigator(s) 

    閉塞性肺疾患発症の主因はタバコ煙をはじめとした有害物質の長期吸入とされるが、罹患者の一部は非喫煙者であり、新規原因物質の特定が待たれている。近年、下気道・肺に微生物が常在することが明らかとなり、検出された菌種から口腔の常在微生物叢(マイクロバイオーム)が主要な供給源であることが指摘されている。我々は、口腔マイクロバイオームの量や質の悪化が、下気道における慢性炎症リスクに寄与しているとの仮説を立てた。本研究では、口腔マイクロバイオームの量や質の悪化が下気道・肺のマイクロバイオーム、肺機能などの検査所見や臨床症状へ及ぼす影響の検討を目的とする。閉塞性肺疾患を有する患者(患者群)と有しない患者(対照群)由来の唾液・舌苔および気管支被覆液を採取し、マイクロバイオームの性状について患者群間および群内での比較解析を行う。患者群および対照群のマイクロバイオームに影響を与える因子の同定・比較検討や、マイクロバイオームの差異が肺機能・胸部CT画像所見・臨床症状へ及ぼす影響の検討を行う。
