Objective Data on uveitis in juvenile psoriatic arthritis (JPsA), a category of juvenile idiopathic arthritis (JIA), are scarce. We describe prevalence and risk factors for JPsA-associated uveitis (JPsA-U). Methods Cross-sectional data from the National Pediatric Rheumatological Database (from 2002 to 2014) were used to characterize JPsA-U and assess risk factors for uveitis development. Results Uveitis developed in 6.6% of 1862 JPsA patients. JPsA-U patients were more frequently female (73.0 vs 62.9%, p=0.031), ANA positive (60.3 vs 37.0%, p<0.001), younger at JPsA onset (5.3 ± 4.1 vs 9.3 ± 4.4 years, p<0.001), and received DMARD (disease modifying antirheumatic drug) treatment significantly more frequently than JPsA patients without uveitis. On multivariable analysis of a subgroup of 655 patients, mean cJADAS during study documentation was significantly associated with uveitis development. Children with early onset of JPsA were significantly more frequently ANA positive (48.4% vs 35.7% for those younger than 5 years at JPsA onset versus those aged 5 years and older, p<0.001), less often affected by skin disease (55.3% vs 61.0%, p=0.032), but more frequently by uveitis (17.3% vs 3.8%, p<0.001), and required DMARD treatment more frequently (52.9% vs 43.8%, p<0.001). Conclusion The characteristics of JPsA patients developing uveitis are similar to those of patients with uveitis in other JIA categories, such as oligoarticular JIA. Especially those children with early onset of JPsA seem to be at a higher risk for ocular involvement. Our data support the notion of a major clinical difference between those patients with early versus late onset of JPsA.
