Abstract
Background: The application of biologic agents has benefited patients with Behcet's uveitis (BU) who do not respond to conventional treatment regimens. However, there is currently no consensus on the optimal treatment regimen of interferon alpha-2a (IFN-α2a) for refractory BU.
Objectives: To evaluate treatment outcomes and safety of IFN-α2a in a large series of refractory BU patients and to explore whether nonbiologic immunomodulatory agents (cyclosporin A) other than corticosteroids should be concomitantly used.
Design: We conducted a retrospective cohort study, which included 153 BU patients who received IFN-α2a treatment between December 2012 and September 2023 with a minimum duration of 6 months.
Methods: Best-corrected visual acuity (BCVA), the frequency of uveitis relapse, corticosteroid-sparing effect, and side effects were evaluated.
Results: Of the 153 patients enrolled, 87 patients were treated with IFN-α2a plus corticosteroids (IC), and 66 patients were treated with IFN-α2a plus corticosteroids and cyclosporin A (ICC). Both IFN-α2a treatment regimens significantly improved BCVA as early as 2 months following treatment, and the improvement was maintained over at least a 2-year follow-up. At the final visit, 86.8% and 73.1% of the affected eyes in the ICC and IC groups achieved improved or stable vision, respectively. The ICC regimen was more effective at improving vision (p = 0.01). Overall, the frequency of uveitis relapse and the dose of oral prednisolone were significantly reduced in both groups after treatment (all p < 0.0001). However, there were no statistically significant differences in these parameters between the two groups. None of the included patients experienced serious side effects that led to the discontinuation of IFN-α2a therapy.
Conclusion: IFN-α2a treatment is a promising option for patients with refractory BU. Our results showed that cyclosporin A as an adjunct could enhance the therapeutic effect of IFN-α2a.
