Background: Psoriasis is a chronic inflammatory disease of the skin with joint manifestations. Psoriasis severity and lower response to treatment have been linked to obesity. But the effect of weight reduction by non-pharmacologic intervention on disease severity is still questionable. This is a systematic review and meta-analysis of randomized-controlled trials (RCT) of the effect of dietary and lifestyle weight loss interventions on psoriasis severity. Methods: We comprehensively searched PubMed/MEDLINE, EMBASE, and CENTRAL from their inception to August 2014. Inclusion criteria were randomized controlled studies that examined lifestyle intervention by diet or exercise in overweight or obese patients with psoriasis and measured the severity of psoriasis as an outcome compared with controls. Two authors independently assessed article quality and extracted the data. Results: From 11 full-text articles, 6 RCT involving 842 participants met our inclusion criteria, and 5 studies were included in the meta-analysis that was based on the random effects model. There was a greater reduction of Psoriasis Area Severity Index (PASI) score in those receiving weight loss intervention compared with controls with a pooled mean difference of −2.23 (95% CI −3.77 to −0.69). More participants in the intervention group achieved a 75% reduction in PASI (PASI 75) than those in the control group with pooled OR=2.92 (95% CI 1.39–6.13). Conclusion: Non-pharmacologic, non-surgical weight loss intervention is associated with reduction in the severity of psoriasis in overweight or obese patients. However, more randomized controlled studies with more participants or on different weight loss methods are needed to provide better quality of evidence.
