This study aims to estimate the effect of synthetic and biologic disease-modifying antirheumatic drugs (DMARDs) on radiographic progression and quality of life in adult patients with psoriatic arthritis. A comprehensive search was performed using MEDLINE, Embase, Web of Science, Scopus, and Cochrane Central Register of Controlled Trials (CCRCT). Clinical trials comparing DMARDs with placebo for ≥ 12 weeks were included. The meta-analysis was conducted with a random-effects model using mean differences (MD). A total of 16 trials with overall moderate quality of evidence were included. Exposure to a biologic agent reduced radiographic progression at 24 weeks of treatment (MD: − 0.66; [95% CI − 0.97 to − 0.34]; P <.00001; I2 = 100%). The reduction of the baseline score was more than two times higher for TNF blockers compared with IL-17 and IL-12/IL-23 inhibitors (MD: − 0.94 vs − 0.41). Improvement in health-related quality of life scores was observed in biologic-treated populations (MD: − 0.21; [95% CI − 0.25 to − 0.18]; P <.00001; I2 = 97%). No sufficient data were available regarding conventional synthetic agents. Our data analyses suggest a better control of radiological damage with bDMARDs, as compared to placebo, after 24 weeks of treatment. However, the accuracy of these results in real life are jeopardized by the exceedingly high level of heterogeneity exhibited within and across included studies, and the true intervention effect cannot be determined with confidence. Further research is required to assess long-term outcomes and to control heterogeneity in the evaluation of treatments for psoriatic arthritis. PROSPERO registration number: CRD42019122223. Key Points • Radiographic progression is not the primary outcome for most efficacy studies in psoriatic arthritis; hence, baseline data are substantially diverse in major clinical trials. • The best available evidence on this particular outcome is currently at a moderate risk of bias. • Existing reports of the effect of DMARDs on structural damage must be taken with caution. • Further research is required to assess long-term outcomes and to control heterogeneity between studies.
