Abstract:AIM: To conduct a systematic review and Meta-analysis to examine the association between uveitis and psoriatic disease, and to evaluate whether one condition predisposes individuals to the other. METHODS: We performed a comprehensive search of PubMed and EMBASE to identify cohort studies examining the association between uveitis and psoriatic disease [psoriasis and/or psoriatic arthritis (PsA)]. We used a random-effects model to calculate the pooled relative risks (RRs) adjusted for confounders, along with the 95% confidence intervals (CIs). RESULTS: This Meta-analysis included a total of 6 studies and a maximum of 80 178 648 participants. Compared with non-psoriatic controls, uveitis risk was significantly elevated in patients with psoriasis (RR=1.49; 95%CI: 1.08-2.07), and PsA (RR=3.16; 95%CI: 2.16-4.63). Furthermore, pre-existing uveitis was associated with a significantly increased risk of psoriasis (RR=1.62; 95%CI: 1.44-1.83), and PsA (RR=4.44; 95%CI: 3.52-5.60). CONCLUSION: The results of this systematic review and Meta-analysis suggest an overall positive bidirectional association between uveitis and psoriatic disease (psoriasis and PsA), warranting increased awareness among clinicians involved in the management of these two conditions. Therefore, there remains a need for more detailed studies of the possible common pathogenesis of psoriatic disease and uveitis.
