In RA, treatment with etanercept has a lower percentage of discontinuation than infliximab and adalimumab. Concomitant use of DMARDs, disease duration before treatment with a biologic and female sex predict time to discontinuation.

Objective. To analyze lipid changes in patients with rheumatoid arthritis (RA) and patients with spondyloarthritis (SpA) treated with biologic agents or tofacitinib in randomized clinical trials (RCTs).Methods. A systematic literature search was performed, using the Medline, Embase, Cochrane Library, and Web of Knowledge databases. Meta-analyses were performed using random-effects models to assess changes in the percentage of patients with abnormal lipid values or in the mean percentage of increase in the cholesterol and triglycerides levels.Results. Conclusion. In patients with RA treated with tocilizumab or tofacitinib but not with TNF antagonists, moderate changes in lipids are observed. Whether these changes pertain to the control of inflammation or to the mechanism of action of the biologic agents or tofacitinib remains undetermined.Rheumatoid arthritis (RA) and the spondyloarthritides (SpA) ankylosing spondylitis and psoriatic arthritis have an important impact on a patient's wellbeing, related partly to joint damage, disability, and poor quality of life but also to increased cardiovascular morbidity and mortality (1-3). The most important cause of death in RA and SpA is cardiovascular disease (4-6).

RCTs are not sensitive enough to assess the risk of reactivation of latent TB infection (LTBI). Disease, treatment and background TB rate are associated with different frequencies of active TB. The benefit/risk balance of preventing reactivation of LTBI in different backgrounds should be considered in clinical practice.
