We performed a systematic review and meta-analysis to evaluate the comparative effects of tumor necrosis factor inhibitors (TNFi), non-TNFi biologics, and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) on cardiovascular risk in rheumatoid arthritis (RA).
Using a systematic search through May 8, 2018, we included 14 observational studies in adults with RA treated with TNFi, non-TNFi biologics, tofacitinib, or csDMARDs, reporting the risk of major adverse cardiovascular events (MACE) or stroke. Only studies reporting active comparators were included. We performed random effects meta-analysis and estimated odds ratios (ORs) and 95% confidence intervals (95% CIs).
As compared to TNFi, tocilizumab was associated with a decreased risk of MACE (OR 0.59 [95% CI 0.34-1.00]), whereas csDMARDs were associated with an increased risk of MACE (csDMARDs including methotrexate OR 1.45 [95% CI 1.09-1.93]; without methotrexate OR 2.57 [95% CI 1.32-5.00]), without heterogeneity (I
Based on meta-analysis, as compared to TNFi, tocilizumab may be associated with a reduced risk of MACE, whereas csDMARDs may be associated with an increased risk of MACE and stroke.
