Clinical characteristics of pediatric noninfectious uveitis and risk factors for severe disease: a single-center study

Abstract

Objectives We aimed to present the demographic, clinical, laboratory, and treatment data of children with non-infectious uveitis and to evaluate the risk factors for the development of complications and the need for biological treatment. Method Patients diagnosed with non-infectious uveitis in childhood and followed up for at least 1 year were included in the study. Demographic data, including age, gender, age at diagnosis, uveitis in first-degree relatives, and rheumatologic diseases, were obtained retrospectively from medical records. The presence of complications or the need for biologic therapy was considered a composite outcome suggesting severe disease. Results The study included 123 patients (female: n = 59, 48%). The mean age at diagnosis was 14.89 ± 4.86 years. Uveitis was symptomatic in 104 patients (84.6%). Approximately one-quarter of the patients had at least one rheumatic disease (n = 35, 28.5%), the most common being juvenile idiopathic arthritis. Thirty-three patients (26.8%) had anti-nuclear antibody positivity. Biologic agents were needed in 60 patients (48.8%). Complications developed in 14 patients (11.4%). Early age at disease onset (aOR, 0.875; 95% C.I. 0.795–0.965, p = 0.007) and female gender (aOR, 2.99; 95% C.I. 1.439–6.248, p = 0.003) were significantly associated with the need for biologic treatment, while Behçet’s disease (BD) was strongly associated with uveitis-related complications (aOR, 14.133; 95% C.I. 2.765–72.231, p = 0.001). Conclusion We suggest that among pediatric patients with non-infectious uveitis, females, those with an early age of disease onset, and those with BD need to be closely monitored due to a significantly increased risk of severe disease. Key Points• Limited data exist on the clinical course of non-infectious uveitis in children and the associated risk factors for severe disease.• Our study reveals that nearly a quarter of pediatric patients with non-infectious uveitis also have a rheumatic disease.• Among pediatric patients diagnosed with non-infectious uveitis, we observed an increased risk of severe disease in those with an earlier onset age, in female patients, and in those diagnosed with Behçet’s disease.
