Association of rheumatoid arthritis-related autoantibodies with pulmonary function test abnormalities in a rheumatoid arthritis registry.

Introduction: We investigated whether rheumatoid arthritis (RA)-related autoantibodies were associated with abnormalities on pulmonary function tests (PFTs).

Methods: We studied RA serostatus and PFT abnormalities within a RA registry. RA serostatus was assessed by research assays for cyclic citrullinated peptide (CCP) and rheumatoid factor (RF).

Correlates of Successful Rheumatoid Arthritis Flare Management: Clinician-driven Treatment, Home-based Strategies, and Medication Change.

Objective: Describe strategies used to manage rheumatoid arthritis (RA) flares that contribute to a successful postflare outcome.

Methods: Data were collected from the BRASS registry, including clinical and patient-reported outcomes, and a survey with a Likert scale assessing postflare symptoms (better, unchanged, or worse). A logistic regression analysis adjusting for age, sex, flare number in the past 6 months, flare pain severity, home management, clinical consultation, and medication change was performed to evaluate factors influencing flare outcome.

Rheumatoid Arthritis Disease Activity Predicting Incident Clinically Apparent Rheumatoid Arthritis-Associated Interstitial Lung Disease: A Prospective Cohort Study.

Objective: To evaluate rheumatoid arthritis (RA) disease activity and risk of RA-associated interstitial lung disease (RA-ILD).

Methods: We investigated disease activity and risk of RA-ILD using the Brigham RA Sequential Study (BRASS, 2003-2016). All patients were diagnosed as having RA according to accepted criteria.

Personalized Risk Estimator for Rheumatoid Arthritis (PRE-RA) Family Study: rationale and design for a randomized controlled trial evaluating rheumatoid arthritis risk education to first-degree relatives.

We present the rationale, design features, and protocol of the Personalized Risk Estimator for Rheumatoid Arthritis (PRE-RA) Family Study (ClinicalTrials.gov NCT02046005). The PRE-RA Family Study is an NIH-funded prospective, randomized controlled trial designed to compare the willingness to change behaviors in first-degree relatives of rheumatoid arthritis (RA) patients without RA after exposure to RA risk educational programs.
