S1P Contributes to Endotoxin-enhanced B Cell Functions Involved in Hypersensitivity Pneumonitis.

Am J Respir Cell Mol Biol 2020 Apr 14. Epub 2020 Apr 14.

Quebec Heart and Lung Institute, 55973, Quebec, Quebec, Canada.

Background: In a proportion of patients with hypersensitivity pneumonitis, biological and environmental factors sustaining inflammation are ill-defined, resulting in no effective treatment option. Bioaerosols found in occupational settings are complex and often include Toll-like receptor ligands, such as endotoxins. How Toll-like receptor ligands contribute to the persistence of hypersensitivity pneumonitis, however, remains poorly understood. Read More

A Systematically Derived Exposure Assessment Instrument for Chronic Hypersensitivity Pneumonitis.

Chest 2020 Jun 17;157(6):1506-1512. Epub 2020 Jan 17.

Department of Medicine, University of California, San Francisco, CA.

Background: Chronic hypersensitivity pneumonitis (CHP) is an immune-mediated interstitial lung disease (ILD) caused by inhalational exposure to environmental antigens, resulting in parenchymal fibrosis. By definition, a diagnosis of CHP assumes a history of antigen exposure, but only half of all patients eventually diagnosed with CHP will have a causative antigen identified. Individual clinician variation in eliciting a history of antigen exposure may affect the frequency and confidence of CHP diagnosis. Read More

Evaluation of Renin and Soluble (Pro)renin Receptor in Patients with IPF. A Comparison with Hypersensitivity Pneumonitis.

Lung 2019 12 15;197(6):715-720. Epub 2019 Oct 15.

Laboratorio de Biología Molecular, Instituto Nacional de Enfermedades Respiratorias, Ismael Cosío Villegas, Mexico City, Mexico.

Introduction: Idiopathic pulmonary fibrosis (IPF) is a lethal disease with an unclear pathogenic mechanism. Components of the renin-angiotensin system (RAS) have a role in the pathogenesis of IPF, specifically, the aspartyl protease renin acts as a profibrotic factor in the lung. However, the concentration of the RAS components renin and soluble (pro)renin receptor (sPRR) have not been previously evaluated neither in serum nor in bronchoalveolar lavage fluid (BAL) of patients with IPF or chronic Hypersensitivity pneumonitis (cHP), a disease which may be confused with IPF.

Case of summer-type hypersensitivity pneumonitis complicated with IgA nephropathy.

BMJ Case Rep 2019 Jun 18;12(6). Epub 2019 Jun 18.

Respiratory Disease Center, Tazuke Kofukai Foundation, Medical Research Institute, Kitano Hospital, Osaka, Japan.

Association between pulmonary disease and IgA nephropathy (IgAN) has been previously reported. However, no association has been reported between hypersensitivity pneumonitis (HP) and IgAN. Here, we report about a patient with no particular medical history, who experienced worsening dyspnoea in the course of 1 month, with ground-glass opacity on chest CT and no improvement after antibiotic therapy.

Pemetrexed-induced Interstitial Lung Disease Mimicking Hypersensitivity Pneumonia: A Pathologically Proven Case.

Intern Med 2019 Sep 7;58(18):2679-2682. Epub 2019 Jun 7.

Department of Respiratory Medicine, Kanagawa Cardiovascular and Respiratory Center, Japan.

We herein report a 45-year-old woman with lung adenocarcinoma stage IV (cT4N3M1a). She was treated with pemetrexed (PEM) monotherapy following four cycles of first-line treatment with carboplatin, paclitaxel, and veliparib. After three cycles of PEM treatment, she presented with dyspnea, and chest computed tomography showed diffuse ground-glass attenuation (GGA), suggesting hypersensitivity pneumonia (HP). Read More

The incidence of ALK inhibitor-related pneumonitis in advanced non-small-cell lung cancer patients: A systematic review and meta-analysis.

Lung Cancer 2019 06 10;132:79-86. Epub 2019 Apr 10.

Department of Radiology, Brigham and Women's Hospital and Dana-Farber Cancer Institute, Harvard Medical School, 450 Brookline Ave, Boston, MA, USA. Electronic address:

Introduction: We evaluated the incidence of pneumonitis in clinical trials of anaplastic lymphoma kinase (ALK) inhibitors in patients with advanced non-small cell lung cancer (NSCLC) and compared the incidence among different cohorts, in order to identify possible predisposing factors for ALK inhibitor-related pneumonitis.

Methods: MEDLINE and EMBASE search up to 1/30/18 using the keywords, "alectinib", "ceritinib", "crizotinib", "brigatinib", and "lung cancer", resulting in a total of 20 eligible cohorts with 2261 patients treated with ALK inhibitor monotherapy for advanced NSCLC. The pooled incidences of all-grade, high-grade, and grade 5 pneumonitis were calculated. Read More
