Patients with systemic autoimmune rheumatic diseases remain at risk for hospitalisation for COVID-19 infection in the Omicron era (2022-2024): a retrospective cohort study.

Objective: To investigate the risk factors for severe acute COVID-19 outcomes in the Omicron era among individuals with systemic autoimmune rheumatic diseases (SARDs).

Methods: We identified patients with confirmed SARDs and COVID-19 (positive PCR and/or antigen test) from 1 September 2022 to 15 March 2024 in the Mass General Brigham healthcare system. We estimated the associations of baseline characteristics with the odds of hospitalisation due to COVID-19 infection, verified by medical record review, using multivariable logistic regression.

Impact of long COVID on self-reported disease activity, disability, and quality of life in individuals with inflammatory arthritis.

Background: People with inflammatory arthritis are at risk for poor COVID-19 outcomes. Little is known about the impact of long COVID on disease activity, disability, and quality of life in this population.

Methods: We included participants with rheumatoid arthritis, psoriatic arthritis, juvenile idiopathic arthritis, or axial spondyloarthritis from RheumCARD, a prospective cohort study of people with rheumatic disease with and without prior COVID-19.
