ObjectiveWe 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).MethodsUsing 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).ResultsAs 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 (I2 = 0%); there was no difference in risk of MACE between abatacept and TNFi (OR 0.89 [95% CI 0.71–1.11]), or between tocilizumab and abatacept (OR 0.81 [0.57–1.16]). Based on 11 cohorts (n = 135,053 patients), as compared to TNFi, csDMARDs were associated with an increased risk of stroke (OR 1.17 [95% CI 1.01–1.36]); there was no difference in risk of stroke between different biologics (tocilizumab versus TNFi OR 0.98 [95% CI 0.59–1.61]; abatacept versus TNFi OR 1.08 [0.86–1.34]; tocilizumab versus abatacept OR 0.73 [95% CI 0.39–1.38]), without heterogeneity (I2 = 0%). No comparative studies on cardiovascular risk with tofacitinib were identified.ConclusionBased 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.

ObjectiveIt is unclear whether isolated cutaneous lupus erythematosus (CLE) affects cardiovascular risk. We estimated the cumulative incidence and mortality of cardiovascular diseases in a population‐based CLE cohort and compared the risk with a matched non‐CLE cohort.MethodsAll incident cases of CLE in Olmsted County, Minnesota, between 1965 and 2005 were followed until December 2013. The cumulative incidence of cerebrovascular accidents (CVAs [including stroke and transient ischemic attack]), ischemic heart disease (IHD [including coronary artery disease, myocardial infarction, and angina pectoris]), heart failure, and peripheral arterial disease (PAD) was derived and compared to an age‐, sex‐, and calendar year–matched non‐CLE cohort using Cox models.ResultsThere were 155 patients with CLE (mean ± SD age at diagnosis 48 ± 16 years, 65% female, mean ± SD BMI 26.3 ± 7.1 kg/m2, 40% smokers, 9% with diabetes mellitus). During a median followup of 14.6 years, 41 CLE patients had cardiovascular events (15 patients with CVAs, 32 patients with IHD), with a 20‐year cumulative incidence of 31.6%. As compared to non‐CLE subjects, the risk of CVAs (smoking‐adjusted hazard ratio [HR] 2.97 [95% confidence interval (95% CI) 1.13–7.78]) and PAD (HR 2.06 [95% CI 0.99–4.32]) was increased in patients with CLE, but the risk of IHD was not increased (HR 0.94 [95% CI 0.57–1.54]). There was no increase in cardiovascular mortality (HR 1.68 [95% CI 0.76–3.75]). The magnitude of risk for any cardiovascular outcome was not significantly influenced by the extent of cutaneous involvement.ConclusionCLE may be associated with an increased risk of CVAs and PAD, but not IHD. Factors contributing to increased CVA risk in patients with CLE merit evaluation.

AbstractWhile fertility is preserved in females with systemic lupus erythematosus (SLE), it is well established that pregnancy in these patients is associated with adverse maternal and fetal outcomes, including pregnancy loss, pre‐eclampsia, preterm delivery and intrauterine growth retardation, as well as neonatal mortality. Mechanisms underlying these adverse outcomes are poorly understood, and better understanding of these would allow development of targeted and personalized treatment strategies. Established risk factors for adverse pregnancy outcomes include active disease within 6 months prior to conception and during pregnancy, active nephritis, maternal hypertension, antiphospholipid antibodies and hypocomplementemia. While intensive monitoring is recommended, the comparative effectiveness of appropriate management strategies is unclear. While current strategies are able to achieve live births in 85–90% of pregnancies, certain aspects such as prevention of preterm birth, treatment of congenital heart block due to neonatal lupus and recurrent pregnancy loss despite best management, remains challenging. Pregnancy is also associated with an increased risk of flare of lupus, particularly in patients with active disease at time of conception or within 6 months prior to conception. Pregnant patients withSLEshould be followed in a high‐risk obstetric clinic, and care should be closely coordinated between the obstetrician and rheumatologist.
