Rise of biologics in noninfectious uveitis: a retrospective cohort study from Nepal

Abstract

Background: Uveitis is a sight-threatening disease that poses a heavy burden on the quality of life. The treatment of uveitis has been revolutionized in the past two decades. Most remarkable among these is the emergence of biologics, which have shown to be effective and safer therapeutic option in noninfectious uveitis. Biologics are very useful when conventional immunomodulator therapy has failed or has been poorly tolerated. The most widely used biologics are tumor necrosis factor-α inhibitors (infliximab and adalimumab) with promising results. Other drugs include anti-CD20 inhibitors (rituximab), interleukin-6R-inhibitor (tocilizumab), interleukin-1R-inhibitor (anakinra), and Janus-associated kinase inhibitor (tofacitinib) Methods: A retrospective review of all cases of noninfectious uveitis and scleritis presenting to our center from July 2019 to January 2021 and had been treated with biological therapy were included. Results: We included 12 eyes of 10 patients. The mean age was 42.10 ± 9.71 years. Anterior nongranulomatous uveitis comprised 70% of the cases and the most common etiology of anterior uveitis was spondyloarthritis (seven cases among which five cases were nonradiographic) axial spondyloarthritis (human leukocyte antigen B27 positive) followed by radiographic axial spondyloarthritis (two cases). The first line of treatment in all cases was conventional synthetic disease-modifying antirheumatic agents among which 50% (n = 5) had received methotrexate (≥ 15 mg/week). As a second line of treatment, one or more biologics was used. Majority of the patients received oral tofacitinib 50% (n = 5) followed by Inj adalimumab 30% (n = 3). One case of Behcet’s disease required sequential biologics (Inj adalimumab followed by oral tofacitinib). All patients tolerated and responded well to the treatment and no recurrences were observed after discontinuation of biologics drugs during the follow-up period of 1 year. Conclusion: Biologics are a relatively safe and effective modality of treatment in refractory, recurrent noninfectious uveitis.
