Advanced therapies in US veterans with rheumatoid arthritis-associated interstitial lung disease: a retrospective, active-comparator, new-user, cohort study.

Background: Uncertainty exists regarding patient outcomes when using TNF inhibitors versus other biological and targeted synthetic disease-modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis-associated interstitial lung disease (ILD). We compared survival and respiratory hospitalisation outcomes following initiation of TNF-inhibitor or non-TNF inhibitor biological or targeted synthetic DMARDs for treatment of rheumatoid arthritis-associated ILD.

Methods: We did a retrospective, active-comparator, new-user, observational cohort study with propensity score matching following the target trial emulation framework using US Department of Veterans Affairs (VA) electronic and administrative health records.

Proteomic profiling of bronchoalveolar lavage fluid uncovers protein clusters linked to survival in idiopathic forms of interstitial lung disease.

Background: Idiopathic interstitial pneumonias (IIPs), such as idiopathic pulmonary fibrosis and interstitial pneumonia with autoimmune features, present diagnostic and therapeutic challenges due to their heterogeneous nature. This study aimed to identify intrinsic molecular signatures within the lung microenvironment of these IIPs through proteomic analysis of bronchoalveolar lavage fluid (BALF).

Methods: Patients with IIP (n=23) underwent comprehensive clinical evaluation including pre-treatment bronchoscopy and were compared with controls without lung disease (n=5).

Airways Abnormalities in a Prospective Cohort of Patients With Rheumatoid Arthritis.

Background: Rheumatoid arthritis (RA) affects roughly 1% of the population and commonly involves the lungs. Of lung involvement in RA, interstitial lung disease (ILD) is well known; however, airways disease in RA is relatively understudied.

Research Question: What are the baseline airways abnormalities in a prospective cohort of patients with RA based on pulmonary function testing (PFT) results, high-resolution CT (HRCT) scans, and computational imaging analysis and are there associations between these abnormalities and respiratory symptoms?

Study Design And Methods: In this single-center study, 188 patients with RA without a clinical diagnosis of ILD underwent HRCT imaging and PFT.

2023 American College of Rheumatology (ACR)/American College of Chest Physicians (CHEST) Guideline for the Treatment of Interstitial Lung Disease in People with Systemic Autoimmune Rheumatic Diseases.

Objective: We provide evidence-based recommendations regarding the treatment of interstitial lung disease (ILD) in adults with systemic autoimmune rheumatic diseases (SARDs).

Methods: We developed clinically relevant population, intervention, comparator, and outcomes questions. A systematic literature review was then performed, and the available evidence was rated using the Grading of Recommendations, Assessment, Development, and Evaluation methodology.
