Abstract

Background and Objective: The effectiveness of biologic treatments in slowing the progression of psoriatic arthritis is well established, but there is limited and conflicting evidence on their ability to prevent the development of psoriatic arthritis in patients with psoriasis. The objective of this review was to evaluate the role of biologic treatment for psoriasis in preventing or delaying subsequent psoriatic arthritis. Methods: A literature search was performed using MEDLINE (PubMed), Embase, Web of Science, and the Cochrane Library for studies published in English from database inception to March 2022 that statistically compared the risk of psoriatic arthritis in patients aged > 16 years who were previously treated with biologic disease-modifying antirheumatic drugs or with other drugs for skin psoriasis. Results: Four articles were eligible for analysis, all retrospective cohort studies. Three were conducted in preselected patients attending dermatology or dermatology–rheumatology collaboration centers and one was a large population-based study. In three studies, a primary two-step statistical analysis yielded a significantly lower risk of psoriatic arthritis in patients treated with biologic agents. These findings were not supported by the large retrospective electronic health record-based study. Conclusions: 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.
