Safety of Intravenous Methylprednisolone in Refractory and Severe Pediatric Uveitis.

Purpose: To evaluate the safety of intravenous high-dose pulse methylprednisolone succinate (IVHDM) in the management of severe or refractory non-infectious pediatric uveitis. Methods: We reviewed all uveitis patients who were ≤16 years of age and who received IVHDM with a dose of ≥500 mg per day (1-3 days a month) for at least 3 months during their management at a tertiary care eye hospital. Results: Twenty pediatric patients with severe or refractory uveitis who received IVHDM were identified. Six patients received IVHDM either once, as a preoperative medication, or at a lower dose than 500 mg, and were excluded. The remaining 14 patients received IVHDM for at least 4 months. Age (mean±SD) was 11.9±2.4 years and 50% were female. Duration of treatment was 14.2±7.5 months. Thirteen patients received IVHDM in combination with other immunomodulatory therapy (IMT). Except for two outliers, IVHDM was given at a dose of 8-25 mg/kg per infusion. Three major adverse events (AEs) occurred in two patients: a single episode of bradycardia, compression fracture following minor trauma and adrenal insufficiency. The number of AEs (major and minor) strongly correlated with duration of treatment (p=0.004) and moderately correlated with the cumulative dose/weight (p=0.051). Weight gain was associated with the use of concomitant oral steroids and not with duration of treatment or cumulative dose. Conclusion: IVHDM may be a valid therapeutic option for aggressive/refractory pediatric uveitis. The reported AEs in this series can also be attributed to the concurrent IMT or the underlying disease itself.
