The index case was a 71-year-old man with no smoking history. He was given a diagnosis of idiopathic interstitial pneumonia at the age of 65. He was admitted to our hospital because of persistent cough and dyspnea on exertion. Two months after initiation of corticosteroid treatment he died of acute exacerbations of interstitial pneumonia. Among his family, four of seven brothers had interstitial pneumonia and all three sons of his were also found to have interstitial pneumonia, and of these seven patients six had a history of smoking. The average age at diagnosis of his generation was 66.5 and that of his son's generation was 45.3. In proband generation chest CT showed traction bronchiectasis or honeycombing in subpleural lesions. In addition, it revealed centrilobular micronodules and interlobular reticular shadow in the second generation. We found 2 single nucleotide polymorphisms of surfactant protein C gene in all children of the proband.

Epidemiological studies indicate that the involvement of the immune system in the pathogenesis of infections associated with chronic obstructive pulmonary disease (COPD), asthma, and interstitial lung disease (ILD) remains unclear. This study aims to assess the potential causal link between infections associated with COPD, asthma, or ILD and immune system function. We conducted a two-sample Mendelian randomization analysis using publicly available genome-wide association study (GWAS) datasets.

: During the acute phase of COVID-19, a number of immunological abnormalities have been reported, but few studies longitudinally analyzed the specific subsets of peripheral blood lymphocytes. : In this observational, prospective, and longitudinal study, adult patients developing acute pneumonia during the COVID-19 pandemic have been followed up for 12 months. Peripheral blood lymphocyte subsets were assessed (with a specific focus on the memory markers) at 6 time points after the disease onset until 12 months.

Lung malignancies, including cancerous lymphangitis and lymphomas, can mimic interstitial lung diseases like cryptogenic organizing pneumonia (COP) on imaging, leading to diagnostic delays. We aimed to identify potential biomarkers to distinguish between these conditions. We analyzed bronchoalveolar lavage fluid from 8 patients (4 COP, mean age 59.

Following the COVID-19 pandemic, the prevalence of pulmonary fibrosis has increased significantly, placing patients at higher risk and presenting new therapeutic challenges. Current anti-fibrotic drugs, such as Nintedanib, can slow the decline in lung function, but their severe side effects highlight the urgent need for safer and more targeted alternatives. This study explores the anti-fibrotic potential and underlying mechanisms of an endogenous peptide (P5) derived from fibroblast growth factor 2 (FGF2), developed by our research team.
