Title: Miscellaneous Rheumatic and Inflammatory Diseases Oral Session II
Session Type: ACR Concurrent Abstract Session
Session Time: 2:30PM-4:00PM
Background/Purpose:
Anti-tumour necrosis factor (TNF) molecules have become a valuable addition to the therapeutic armamentarium for patients with severe uveitis. However, direct comparison of safety and efficacy of infliximab (IFX) and adalimumab (ADA) is lacking.
In this French nationwide study, we analyzed the efficacy and safety of IFX and ADA in patients with severe uveitis.
Methods: 203 patients (31 [20-42] years with 57% of women) with severe uveitis treated with anti-TNF alpha (IFX 5mg/kg at week 0, 2, 6 and every 6 weeks or ADA 40mg/2 weeks) were included. Because of the non-randomized design, the comparison of the anti-TNF treatments was performed using a propensity score approach. The probability of receiving either IFX or ADA, conditionally on baseline characteristics, was computed using a logistic regression model. The comparison of efficacy between IFX and ADA was considered as the primary end-point. Ocular involvement response to treatment was evaluated according to the SUN Workgroup criteria.
Results: Uveitis was bilateral in 163 cases (80%). Main etiologies of uveitis included Behçet’s disease (38%), juvenile idiopathic arthritis (20%), spondylarthropathies (11%) and sarcoidosis (5%). The median duration of disease before starting anti-TNF treatment was 42 [15-104] months. Ninety six percent of patients achieved complete or partial response to anti-TNF alpha therapy. In univariate analysis, the factors associated with complete response of uveitis included Behçet’s disease (OR=5.89 [1.65-21.0], p=0.006) and more than 5 uveitis flares before anti-TNFα treatment (OR: 2.37 [1.13-4.97], p=0.022). In contrast, previous immunosuppressive use was negatively associated with complete response to anti-TNFα (OR=0.25 [0.11-0.54]; p=0.0004). The complete response rate and the time to first improvement of uveitis were similar regardless the anti-TNFα (IFX or ADA) used (OR 0.88 [0.23-3.35]; p=0.85 and 0.93 [0.41-2.10] months; p=0.86, respectively) in a logistic regression model weighted by the inverse of propensity score. Side effects were reported for 28% of patients and 12% had serious adverse events. No significant difference was observed in terms of serious side effects between IFX and ADA (OR 0.25 [0.047-1.29]; p=0.097).
Conclusion: Overall efficacy and safety were equivalent between IFX and ADA in severe uveitis. Behçet’s patients had a 4 times higher odds of complete response to anti-TNFα therapy.
