Résumé

Objectives

To report the safety and efficacy of tocilizumab in patients with severe and refractory non-infectious uveitis.

Methods

Eight consecutive unselected patients with severe and refractory non-infectious uveitis[Birdshot chorioretinopathy (n=1), Behçet’s disease (n=1) and idiopathic bilateral panuveitis (n=6)] treated with tocilizumab (8mg/kg every 4 weeks intravenously) were included. The primary outcome was the response to treatment, defined by decrease of inflammatory ocular signs.

Results

Four (50%) patients were of female gender and the median (IQR) age was 41 (31-47) years. The median number of previous immunosupressants was of 5.5 (4-6.7). Seven patients had been previously treated with anti-TNF-α [infliximab (n=5) and adalimumab (n=2)]. The immunosupressive drugs used in association with tocilizumab were azathioprine (n=2), mycophenolate mofetil (n=2) and methotrexate (n=2). After a median follow-up of 8 months (6-25), 6/8 (75%) improved under tocilizumab and 2 (25%) were non-responders. The visual acuity improved in five patients. The median dose of prednisolone decreased from 16mg/day (10.6-20.5) to 10 mg/day (10-13.7), at baseline and at the end of follow-up, respectively. Tolerance of tocilizumab was satisfactory and side effects included bronchitis (n=1) and grade 1 leukopenia (n=1) and thrombocytopenia (n=1).

Conclusions

Tocilizumab seems to be a safe and promising therapy in severe and refractory non-infectious uveitis.

Objective

To analyze the factors associated with response to anti-tumor necrosis factor (anti-TNF) treatment and compare the efficacy and safety of infliximab (IFX) and adalimumab (ADA) in patients with refractory noninfectious uveitis.

Methods

This was a multicenter observational study of 160 patients (39% men and 61% women; median age 31 years [interquartile range 21-42]) with uveitis that had been refractory to other therapies, who were treated with anti-TNF (IFX 5 mg/kg at weeks 0, 2, 6, and then every 5-6 weeks [n = 98] or ADA 40 mg every 2 weeks [n = 62]). Factors associated with complete response were assessed by multivariate analysis. Efficacy and safety of IFX versus ADA were compared using a propensity score approach with baseline characteristics taken into account. Subdistribution hazard ratios (SHRs) and 95% confidence intervals (95% CIs) were calculated.

Results

The main etiologies of uveitis included Behçet’s disease (BD) (36%), juvenile idiopathic arthritis (22%), spondyloarthropathy (10%), and sarcoidosis (6%). The overall response rate at 6 and 12 months was 87% (26% with complete response) and 93% (28% with complete response), respectively. The median time to complete response was 2 months. In multivariate analysis, BD and occurrence of >5 uveitis flares before anti-TNF initiation were associated with complete response to anti-TNF (SHR 2.52 [95% CI 1.35-4.71], P = 0.004 and SHR 1.97 [95% CI 1.02-3.84], P = 0.045, respectively). Side effects were reported in 28% of patients, including serious adverse events in 13%. IFX and ADA did not differ significantly in terms of occurrence of complete response (SHR 0.65 [95% CI 0.25-1.71], P = 0.39), serious side effects (SHR 0.22 [95% CI 0.04-1.25], P = 0.089), or event-free survival (SHR 0.55 [95% CI 0.28-1.08], P = 0.083).

Conclusion

Anti-TNF treatment is highly effective in refractory inflammatory uveitis. BD is associated with increased odds of response. IFX and ADA appear to be equivalent in terms of efficacy.
