Impact of systemic treatments on the course of HLA-B27-associated uveitis: A retrospective study of 101 patients

Purpose To investigate the efficacy and tolerance of systemic treatments for the prevention of HLA-B27-associated acute uveitis (AU) recurrence. Methods Retrospective review of patients with HLA-B27-associated uveitis followed in our tertiary center over a 15-year period. Systemic treatments were prescribed to patients with frequent (more than 2 flares per year) or severe uveitis, according to a step-up strategy Results 101 patients (51.5% of men, 88.1% of white Europeans) with a median age of 37 years. AU was mostly recurrent (68.3%) and associated with spondyloarthritis (60.4%). After a median follow-up duration of 22 months (3-73), 37.6% of the patients have received systemic treatment. 88.5% of the patients have been treated with sulfasalazine (SSZ) for ophthalmologic purposes (23/26). Methotrexate (MTX) and anti-TNFa agents have been initiated for a rheumatologic indication in 81.8% (9/11) and 100% of the patients (13/13), respectively. The annual uveitis relapse rate significantly decreased on SSZ (0.37 recurrences/year versus baseline 2.46 recurrences/year; p< 0.001) and MTX (1.54 recurrences/year versus 4.17/year; p = 0.008). Patients under ADA for ophthalmologic purposes (n = 2) did not experience any recurrence. Conclusion We report an open-label strategy to prevent the recurrences of HLA-B27-associated AU. First-line sulfasalazine reduced uveitis relapses. The use of anti-TNF alpha agents for ophthalmologic purposes was unnecessary with rare exceptions.
