ABSTRACT

Purpose: To investigate the long-term efficacy and safety of interferon alpha-2a (IFNα-2a) in Chinese patients with Behçet’s uveitis (BU) refractory to conventional therapy.

Methods: In a prospective observational cohort study, 127 patients were treated with an initial dosage of 3 million units per day in the first three months, followed by gradual tapering of the dose.

Results: After 3 months of treatment, IFNα-2a was shown to be effective in 115 cases (91%). At the end of the 1-year follow-up, the frequency of ocular relapses decreased to 1.59 ± 1.68 per year (ranging 0–6) (p < 0.001), as compared to 5.09 ± 2.51 per year (ranging 3–15). Moreover, the frequency of oral ulcer relapses also decreased to 2.49 ± 1.84 per year (ranging 0–6) (p < 0.001), as compared to 8.20 ± 3.72 per year (ranging 2–10). Visual improvement or stability was observed in 32 patients (59%) in these 54 patients. During a mean follow-up of 11 months (range 3–33), the mean final VA (logMAR) had progressed from 1.0 logMAR to 0.8 logMAR in all treated patients.

Conclusions: Long-term low dose of IFNα-2a is useful in treating Chinese BU patients who do not respond adequately to conventional therapy.
