BackgroundSeveral studies have shown a relationship between psoriasis and metabolic syndrome (MS), but no meta-analysis has been restricted to studies that adjusted for confounders.ObjectiveTo determine the association between psoriasis and MS.MethodsA systematic review and meta-analysis of observational studies on psoriasis and MS in adults was performed from MEDLINE, Scopus, SciELO, Google Scholar, Science Direct, and LILACS from inception to January 2016. We performed a random effects model meta-analysis for those studies reporting adjusted odds ratios (ORs) with 95% confidence intervals (CIs). The subgroup analysis was related to geographic location, diagnosis criteria and risk of bias.ResultsIn all, 14 papers including a total of 25,042 patients with psoriasis were analyzed. We found that MS was present in 31.4% of patients with psoriasis (OR, 1.42; 95% CI, 1.28-1.65). Middle Eastern studies (in Israel, Turkey, and Lebanon) (OR, 1.76, 95% CI, 0.86-2.67) reported a greater risk for MS than European studies (in Germany, Italy, the United Kingdom, Norway, and Denmark) (OR, 1.40; 95% CI, 1.25-1.55).LimitationsFew adjusted studies existed, and there was inconsistency between publications.ConclusionBecause of the increased risk for MS, clinicians should consider screening patients with psoriasis for metabolic risk factors.Copyright © 2017 American Academy of Dermatology, Inc.
