Respiratory investigation 64(4) 101463-101463 2026年6月5日BACKGROUND: Nintedanib is widely used for idiopathic pulmonary fibrosis (IPF) and progressive fibrosing interstitial lung disease (PF-ILD). However, real-world data regarding its efficacy and safety in patients aged 75 years or older remain limited. This study aimed to evaluate these parameters in an older Japanese population. METHODS: We retrospectively enrolled patients who initiated nintedanib for IPF or PF-ILD between August 2019 and July 2023 across 15 institutions. Patients were stratified into the older group (≥75 years) and the younger group (<75 years). Clinical outcomes, including annual forced vital capacity (FVC) decline and the incidence of adverse events, were compared. RESULTS: The older and younger groups comprised 191 and 222 patients, respectively. The median survival time after nintedanib initiation was significantly shorter in the older group (1054 vs. 1400 days). The annual FVC change after nintedanib initiation was -61.3 and -61.4 mL/year for the younger and older groups, respectively. Although older patients frequently required dose reductions or had shorter treatment durations, the overall adverse events incidence remained similar (65.4% in the older group vs. 68.9% in the younger group). No significant differences were observed in the time to adverse events onset or severity. CONCLUSIONS: In real-world clinical practice, nintedanib demonstrated comparable efficacy in attenuating pulmonary function decline and a similar safety profile in older patients compared to younger patients. The shorter survival in older patients likely reflects diminished physiological reserve against respiratory events rather than reduced therapeutic efficacy. These findings support nintedanib use for interstitial lung disease in older populations.

BMC pulmonary medicine 2026年5月19日BACKGROUND: The neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation, with prognostic value in interstitial lung disease (ILD). However, the association between baseline NLR and the therapeutic efficacy of nintedanib remains unclear. This study investigates the relationship between baseline NLR values and clinical outcomes in patients with idiopathic pulmonary fibrosis (IPF) and progressive fibrosing-ILD (non-IPF ILD) receiving nintedanib therapy. METHODS: This retrospective multicenter study included 406 patients-169 with IPF and 237 with non-IPF ILD-who initiated nintedanib treatment between 2019 and 2023 across 15 institutions in Japan. Patients were stratified into low- and high-NLR groups using a cutoff of 2.86. Comparative analysis assessed survival time, forced vital capacity (FVC) changes, and acute exacerbations. RESULTS: The high-NLR group demonstrated shorter median survival time in the overall study population (1,171 vs. 1,386 days; p =0.025). In subgroup analyses, higher NLRs were associated with shorter survival time in patients with IPF (778 vs. 1,447 days; p =0.006), but not in the non-IPF ILD group. While nintedanib mitigated FVC decline in most subgroups, this effect was attenuated in patients with IPF and high-NLR, with no statistically significant benefit (-8.63% vs. -6.71%). In multivariable analysis, NLR was not found to be an independent predictor of the annual relative FVC decline in any group. The incidence of acute exacerbations did not differ significantly between groups. CONCLUSIONS: While baseline NLR did not independently predict the annual relative FVC decline, it was identified as a significant independent predictor of survival time in patients with ILD, particularly those with IPF, following the initiation of nintedanib.

Anticancer research 46(5) 2789-2806 2026年5月BACKGROUND/AIM: Cancer cachexia, characterized by weight loss and systemic inflammation, has been associated with poor prognosis in non-small cell lung cancer (NSCLC). However, its impact on treatment outcomes in tumors with mutant epidermal growth factor receptor (EGFR) remains unclear. This multicenter retrospective cohort study evaluated the impact of cancer cachexia on treatment selection after the development of resistance to EGFR tyrosine kinase inhibitors (TKIs). PATIENTS AND METHODS: This study included 439 patients with advanced EGFR-mutant NSCLC who received chemotherapy (n=304) or immune checkpoint inhibitors (ICIs) combined with chemotherapy (n=135) after EGFR-TKI failure. Cancer cachexia was diagnosed based on specific weight loss criteria and laboratory data. Propensity score matching was performed to adjust for baseline differences, and survival outcomes were compared. RESULTS: Overall, significant differences in treatment outcomes were observed between the groups. In the chemotherapy group, cancer cachexia was an independent predictor of overall survival (hazard ratio=1.53; p=0.004), whereas it was not associated with survival in the ICIs/chemotherapy group. Among patients with cachexia, overall survival was significantly longer with ICIs/chemotherapy than with chemotherapy alone (13.8 vs. 11.2 months; p=0.049). CONCLUSION: Although no significant survival difference was found between chemotherapy and ICIs/chemotherapy in the overall population, ICIs/chemotherapy conferred a survival benefit to patients with cancer cachexia. These findings suggest that the presence of cachexia may serve as a potential biomarker for treatment selection in EGFR-TKI-resistant, EGFR-mutant NSCLC.

Fujita medical journal 11(3) 121-128 2025年8月OBJECTIVES: To develop a comprehensive machine learning model incorporating various clinical factors, including frailty and comorbidities, to predict 30-day readmission and mortality risk in patients with chronic obstructive pulmonary disease (COPD). METHODS: This retrospective cohort study used electronic health records (EHR) from Fujita Health University Hospital (2004-2019) for 1294 patients with COPD and 3499 hospitalization or death events. The EHR contained longitudinal patient data (demographics, diagnoses, test results, clinical records). We developed two eXtreme Gradient Boosting models, the comprehensive Top64 and practical 11-feature models. We compared these with the Comorbidity, Obstruction, Dyspnea, and Previous Exacerbations index (CODEX) model, a widely used tool for predicting hospital readmission or death in patients with COPD. The area under the receiver operating characteristic curve (AUC) with 95% confidence interval (CI), sensitivity, and specificity were used to evaluate the model performance. RESULTS: The Top64 (AUC: 0.769, 95% CI: 0.747-0.791) and practical 11-feature (AUC: 0.746, 95% CI: 0.730-0.762) models performed better than the CODEX model (AUC: 0.587, 95% CI: 0.563-0.611). The Top64 model showed 0.978 sensitivity and 0.341 specificity, and the practical 11-feature model achieved 0.955 sensitivity and 0.361 specificity. The calibration curves showed good agreement between the observed and predicted results for both models. CONCLUSIONS: A machine learning approach based on clinical data readily available from the EHR performed better than existing models in predicting 30-day readmission and mortality risks in patients with COPD. A comprehensive risk prediction tool may enhance individualized care strategies and improve patient outcomes in COPD management.

Heart and vessels 2025年7月21日Duchenne muscular dystrophy (DMD) is a progressive myopathy caused by a mutation in the dystrophin gene. Cardiac disease is currently the leading cause of death in patients with DMD; thus, early diagnosis and management of cardiomyopathy are essential. Intra-voxel incoherent motion (IVIM) analysis provides quantitative values from diffusion-weighted imaging (DWI) and may serve as a novel index for evaluating myocardial properties in DMD. We conducted IVIM analysis in patients with DMD and compared their results with those of healthy volunteers to confirm that IVIM analysis can detect myocardial damage more effectively than conventional imaging methods. Patients with DMD who underwent cardiac magnetic resonance IVIM were enrolled. D and F values were measured using DWI of the left ventricle. Six healthy volunteers served as the control group. Twelve male patients with DMD were enrolled (median age, 14 years). Creatinine kinase levels were elevated, brain natriuretic peptide values remained within the normal range, and troponin T levels were only mildly elevated. The D value in patients with DMD was significantly higher than that in healthy volunteers, indicating increased diffusion in the myocardium (2.59 vs. 1.85, p = 0.0057); however, the F value was comparable between the two groups (0.62 vs. 0.61, p = 0.60). The D and F values from IVIM analysis provided a more detailed reflection of myocardial properties. Myocardial diffusion in patients with DMD was elevated compared with that in healthy volunteers.

Nihon Shokakibyo Gakkai zasshi = The Japanese journal of gastro-enterology 122(4) 297-304 2025年A 60-year-old male patient with metastasis from sigmoid colon cancer in the pancreatic uncinate process who received chemotherapy was treated with edoxaban (EDO) because of deep vein thrombosis. The pancreatic metastasis appeared to shrink, but the patient had repeated acute pancreatitis. An upper gastrointestinal endoscopy was performed to determine the cause. Bleeding from the major papilla and the minor papilla was detected, and he was diagnosed with hemosuccus pancreaticus. Pancreatic duct stenting was conducted from the minor papilla. The pancreatitis was then improved and the EDO dosage was reduced. The pancreatic duct stent fell off during the course. Hemosuccus pancreaticus has not relapsed after 1 year from the dropout of the stent. EDO was considered responsible for hemosuccus pancreaticus.
