Article Synopsis
  • Fibrotic hypersensitivity pneumonitis (FHP) is an interstitial lung disease linked to unclear immune reactions, and researchers studied immune cells from various patient groups using single-cell RNA sequencing.
  • The analysis revealed an increase in specific immune cells, including classical monocytes and GZM cytotoxic T cells, in FHP patients compared to controls and those with idiopathic pulmonary fibrosis (IPF).
  • These findings highlight unique immune disturbances in FHP, suggesting potential new biomarkers and treatment strategies based on the distinct inflammatory responses observed in the disease.

Background: Honeycomb cysts (HC) within the alveolar region are distinct histopathological features in the lungs of idiopathic pulmonary fibrosis (IPF) patients. HC are lined with a single-or stratified layer of basal cells (BC), or with a bronchiolar-like epithelium composed of basal-, ciliated- and secretory epithelial cells. By using cultured IPF patient-derived alveolar BC, we aimed to establish an in vitro- and in vivo model to mimic HC formation in IPF.

Autoimmunity plays a role in certain types of lung fibrosis, notably connective tissue disease-associated interstitial lung disease (CTD-ILD). In idiopathic pulmonary fibrosis (IPF), an incurable and fatal lung disease, diagnosis typically requires clinical exclusion of autoimmunity. However, autoantibodies of unknown significance have been detected in IPF patients.

Article Synopsis
  • * Researchers analyzed various data from IPF patients, finding elevated levels of the chemokine CXCL6, which correlates with poorer patient survival.
  • * The study suggests that CXCL6, produced by abnormal airway epithelial cells, enhances collagen production in lung fibroblasts, contributing to the pathology of IPF and highlighting a potential target for treatment.

Rationale And Objectives: The extent and commonality of peripheral blood immune aberrations in fibrotic interstitial lung diseases are not well characterized. In this study, we aimed to identify common and distinct immune aberrations in patients with idiopathic pulmonary fibrosis (IPF) and fibrotic hypersensitivity pneumonitis (FHP) using cutting-edge single-cell profiling technologies.

Methods: Single-cell RNA sequencing was performed on patients and healthy controls' peripheral blood and bronchoalveolar lavage samples using 10X Genomics 5' gene expression and V(D)J profiling.

Introduction: In the INBUILD trial in patients with progressive pulmonary fibrosis other than idiopathic pulmonary fibrosis (IPF), nintedanib slowed the rate of decline in forced vital capacity (FVC; mL/year) over 52 weeks compared with placebo. We assessed the efficacy of nintedanib across subgroups in the INBUILD trial by baseline characteristics.

Methods: We assessed the rate of decline in FVC over 52 weeks and time to progression of interstitial lung disease (ILD) (absolute decline from baseline in FVC % predicted > 10%) or death over the whole trial in subgroups based on sex, age, race, body mass index (BMI), time since diagnosis of ILD, FVC % predicted, diffusing capacity of the lungs for carbon monoxide (DLco) % predicted, composite physiologic index (CPI), GAP (gender, age, lung physiology) stage, use of anti-acid therapy and use of disease-modifying antirheumatic drugs (DMARDs) at baseline.

Article Synopsis
  • * Researchers studied 1,909 sarcoidosis patients across Europe, genotyping them for specific genetic markers to see if there were connections between these markers and the disease's various phenotypes.
  • * The study found no broad genetic associations after adjusting for multiple tests, but did identify specific genetic links to acute onset in certain regions (like Serbia and Poland), implying that local environmental factors might influence these genetic effects.

Hemoptysis resembles a clinical emergency and necessitates a fast and well-coordinated diagnostic and therapeutic approach. While up to 50% of the underlying causes remain unidentified, the majority of cases in the western world can be attributed to respiratory infections and pulmonary neoplasm. While 10% of the patients present with massive, life-threatening hemoptysis, which require a timely airway protection in order to secure a sustained pulmonary gas-exchange, the vast majority presents with non-critical pulmonary bleeding events.

The evaluation of a patient with interstitial lung disease (ILD) includes assessment of clinical, radiological, and often histopathological data. As there were no specific recommendations to guide the evaluation of patients under the suspicion of an ILD within the German practice landscape, this position statement from an interdisciplinary panel of ILD experts provides guidance related to the diagnostic modalities which should be used in the evaluation of ILD. This includes clinical assessment rheumatological evaluation, radiological examinations, histopathologic sampling and the need for a final discussion in a multidisciplinary team.

Sjögren's syndrome (SjS) is a possible autoimmune cause of interstitial lung disease. The diagnostic pathway for SjS, however, is largely undefined in comparison to other systemic autoimmune diseases. Subjective sicca symptoms, anti-SS-A/Ro antibodies and even ANA as screening tests all have relevant limitations in sensitivity and/or specificity.

The SARS-CoV-2 pandemic had a tremendous impact on diagnosis and treatment of interstitial lung diseases (ILD). Especially in the early phase of the pandemic, when the delta variant was prevailling, a huge number of viral pneumonias were observed, which worsened pre-existing, triggered de novo occurence or discovery of previously subclincal interstitial lung diseases. The effect of SARS-CoV-2 infection - without or with accompanying viral pneumonia - on the further development of pre-existing ILD as well of new pulmonary inflitrates and consolidiations is difficult to predict and poses a daily challenge to interdisciplinary ILD boards.

Article Synopsis
  • Idiopathic pulmonary fibrosis (IPF) is a serious and progressive lung disease linked to changes in metabolism, mitochondria, and cellular cleanup processes in lung cells.
  • The microRNA-33 (miR-33) family regulates metabolism and impacts macrophage responses, showing increased levels in lung fluid from IPF patients compared to healthy individuals.
  • By removing miR-33 in macrophages, researchers demonstrated reduced lung fibrosis and inflammation, suggesting that targeting miR-33 could offer a new treatment strategy for IPF.

Background And Objective: The minor T-allele of the MUC5B promoter polymorphism rs35705950 is strongly associated with idiopathic pulmonary fibrosis (IPF). However, conflicting results have been reported on the relationship between the MUC5B minor allele and survival and it is unknown whether a specific subgroup of IPF patients might benefit from MUC5B minor allele carriage. We investigated the association between MUC5B rs35705950, survival and patient characteristics in a real-world population of European IPF patients.
