BackgroundPsoriasis is associated with health-related quality-of-life impairment and depression.ObjectiveWe sought to determine the effect of adalimumab on depression symptoms in patients with psoriasis.MethodsPatients with moderate to severe psoriasis in a randomized, placebo-controlled, double-blind clinical trial were assessed for depression symptoms at baseline and week 12 or early termination (ET) using the Zung Self-rating Depression Scale (ZDS). The effects of adalimumab (40 mg every other week) versus placebo on ZDS score at week 12/ET were assessed using analysis of covariance. Relationships between ZDS and the Psoriasis Area and Severity Index (PASI), the Dermatology Life Quality Index, and the Short Form 36 Health Survey were assessed using Pearson correlations. Changes in ZDS score were compared for patients with and without a 75% or greater reduction in baseline PASI score.ResultsCompared with the placebo group (n = 52), the adalimumab group (n = 44) experienced an additional 6-point reduction in ZDS score (95% confidence interval: 2.5-9.5; P < .001) by week 12/ET. Depression improvement was correlated with improvement in PASI (r = 0.5; P < .0001) and Dermatology Life Quality Index (r = 0.5; P < .0001). Greater ZDS score improvement was observed at week 12/ET in responders with a 75% or greater reduction in baseline PASI score than in nonresponders (10.6 [SD = 9.4] vs 1.4 [SD = 9.6]; P < .001).LimitationsThis analysis cannot distinguish whether adalimumab has a direct or indirect effect on depression.ConclusionsAdalimumab treatment reduced psoriasis symptoms, reduced depression symptoms, and improved health-related quality of life in patients with moderate to severe psoriasis.
