Cardiovascular Safety of Biologics and JAK Inhibitors in Patients with Rheumatoid Arthritis.

PURPOSE OF REVIEW

Increased cardiovascular (CV) risk and associated mortality in rheumatoid arthritis (RA) are not fully explained by traditional CV risk factors. This review discusses the epidemiology and mechanisms of increased CV risk in RA and treatment effects on CV risk focusing on biologic disease-modifying anti-rheumatic drugs (DMARDs) and JAK inhibitors.

RECENT FINDINGS

Intermediary metabolic changes by inflammatory cytokines are observed in body composition, lipid profile, and insulin sensitivity of RA patients, leading to accelerated atherosclerosis and increased CV risk. Successful treatment with DMARDs has shown beneficial effects on these metabolic changes and ultimately CV outcomes, in proportion to the treatment efficacy in general but also with drug-specific mechanisms. Recent data provide further information on comparative CV safety between biologic DMARDs or JAK inhibitors as well as their safety signals for non-atherosclerotic CV events. CV benefits or safety signals associated with DMARD treatments can differ despite similar drug efficacy against RA, suggesting that both anti-inflammatory and drug-specific mechanisms are involved in altering CV risk.
