Longitudinal association between nailfold capillaroscopy and incident interstitial lung disease: A EUSTAR database analysis.

Objectives: To evaluate (1) the association between nailfold capillaroscopy pattern and 5-year risk for incident interstitial lung disease and (2) the association between transition in nailfold capillaroscopy pattern and risk of incident interstitial lung disease.

Methods: Data of adult patients from the EUSTAR database fulfilling the ACR-EULAR criteria with a disease duration ⩽5 years, having a scleroderma pattern at nailfold capillaroscopy with high-resolution computed tomography confirmed absence of interstitial lung disease (i.e.

Gastroesophageal reflux disease is associated with a more severe interstitial lung disease in systemic sclerosis in the EUSTAR cohort.

Objectives: Gastroesophageal reflux disease (GERD) is frequent in systemic sclerosis (SSc) and could predict progression of interstitial lung disease (ILD). We aimed to analyse (1) the prevalence of GERD among SSc-ILD patients, (2) its association with disease characteristics and (3) predictive factors for ILD progression in SSc-ILD patients with GERD.

Methods: SSc patients from the EUSTAR database with ILD were included.

Evaluation of rheumatoid arthritis-associated interstitial lung disease in patients treated with JAK inhibitors: a MAJIK-SFR cohort study.

Objective: To examine the course of interstitial lung disease associated with rheumatoid arthritis (RA-ILD) in France on treatment with Janus kinase inhibitors (JAKis) using the MAJIK-SFR registry.

Methods: Prospective national multicentre observational study identifying patients with RA-ILD from the MAJIK-SFR registry. Pulmonary assessment data were collected at JAKi initiation and follow-up visits (6 months, 12 months and a median of 21 months postinclusion), including chest high-resolution CT (HRCT), pulmonary function tests (forced vital capacity (FVC) and diffusing capacity of the lungs for carbon monoxide (DLCO)), acute exacerbations of ILD, respiratory infections and lung cancers.

Crystalline silica on the lung-environment interface: Impact on immunity, epithelial cells, and therapeutic perspectives for autoimmunity.

Crystalline silica (the most abundant form of silicon dioxide) is a natural element that is ubiquitous in the Earth's crust. Chronic personal or professional exposure has been implicated in various pathologies, including silicosis and autoimmune diseases since the early 20th century. More recently, a specific pathogenic role for crystalline silica has been identified through its impact on lung epithelial cells as well as immune cells present at this organism barrier.

Altered X-chromosome inactivation of the TLR7/8 locus and heterogeneity of pDCs in systemic sclerosis.

Systemic sclerosis (SSc) is an autoimmune disease that has a strong female predominance. Both the X-linked TLR7 and TLR8 can induce type I IFN (IFN-I) by plasmacytoid DCs (pDCs), which can promote fibrosis. We identified five subclusters of pDCs, including ISGhigh clusters that were over-represented in SSc patients.
