Pulmonary-renal syndrome is a common and serious disorder with a broad differential diagnosis. We describe a case of a middle-aged man presenting with interstitial pulmonary disease and severe renal impairment caused by a hypocomplementemic immune-complex-mediated interstitial nephritis. Serum levels of IgG4 were elevated, and renal biopsy specimens revealed the presence of interstitial IgG4(+) plasma cells. There was a rapid improvement of both pulmonary and renal abnormalities after the initiation of corticosteroids. To our knowledge, this report is the first to show interstitial pulmonary disease in association with interstitial kidney disease as the predominant and presenting symptoms of IgG4-related disease.

Dendriform pulmonary ossification (DPO) is a rare condition characterized by mature bone formation in the lung. DPO has been linked to various conditions, but little is known about the link between DPO and hazardous airborne exposures. We queried research databases of military personnel evaluated for deployment-related respiratory diseases at two occupational pulmonary medicine clinics (Colorado, USA) for diagnoses of DPO, and summarized demographics, Gulf War military deployment history, medical history, and pulmonary function testing.

Porcine reproductive and respiratory syndrome virus (PRRSV) causes significant economic losses in the global swine industry due to its high genetic diversity and different virulence levels, which complicate disease management and vaccine development. This study evaluated longitudinal changes in the immune cell composition of bronchoalveolar lavage fluid and the clinical outcomes across PRRSV strains with varying virulence, using techniques including single-cell transcriptomics. In highly virulent infection, faster viral replication results in an earlier peak lung-damage time point, marked by significant interstitial pneumonia, a significant decrease in macrophages, and an influx of lymphocytes.

Objective: This study aimed to share the process of epidemiologic survey and demonstrate the decisive factors for evaluating work-related Idiopathic interstitial pneumonias (IIPs) in Korea.
Methods: Data and reports of epidemiologic surveys were investigated and completed during 2010-2022.
Results: A total of 228 idiopathic pulmonary fibrosis (IPF) cases requested for an epidemiologic survey, of which 153 (67.

Object: Patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) have a high risk of serious infection, in particular severe pneumonia. This study aimed to investigate the transcriptional landscape, lower respiratory tract (LRT) microbiome and metabolomic profiles in the lung of RA-ILD patients with pneumonia.
Method: A total of 10 RA-ILD with pneumonia were enrolled in this study.
