Purpose: To describe the effectiveness of leflunomide as adjunctive therapy with anti-tumor necrosis factor (anti-TNF) agents in pediatric patients with uveitis who are not able to tolerate methotrexate.
Methods: A retrospective case series was performed of pediatric patients who were receiving leflunomide in conjunction with anti-TNF agent therapy after intolerance to a combination of methotrexate with anti-TNF therapy. Dose and duration of methotrexate, leflunomide, and anti-TNF therapy were recorded. Extensive history, demographics, laboratory data, and uveitis flare rate were obtained.
Results: A total of five children were included in the study. Most patients were initially receiving methotrexate and an anti-TNF agent was added subsequently due to inadequate response to monotherapy. After discontinuation of methotrexate, leflunomide was initiated with anti-TNF therapy. The replacement of methotrexate with leflunomide showed decreased side effects and was associated with lower flare rates and steroid-free remission.
Conclusions: Leflunomide was found to be well tolerated and effective at maintaining uveitis quiescence in conjunction with anti-TNF agents in pediatric patients who do not tolerate methotrexate. [J Pediatr Ophthalmol Strabismus. 2023;60(6):417-420.].
