Do Biologic Treatments for Psoriasis Lower the Risk of Psoriatic Arthritis? A Systematic Review.

Biologic treatments may be effective in preventing the development of psoriatic arthritis in patients with psoriasis. More research is needed given the retrospective cohort design of all studies included in the review limiting the generalizability of the results, and the conflicting results from the registry study. At present, biologic agents should not be prescribed to unselected patients with psoriasis for the sole purpose of preventing psoriatic arthritis.
