AB0669 Maintenance treatment with adalimumab in refractory uveitis due to behÇet’s disease: optimised vs non-optimised group

Background Uveitis is the most common ocular manifestation in Behcet’s Disease (BD), which can cause irreversible blindness.1–2 Objectives To assess efficacy, safety and cost-effectiveness of adalimumab (ADA) therapy optimisation in a series of patients with uveitis due to BD. Methods Multicenter study of 74 ADA-treated patients with BD uveitis refractory to conventional immunosuppressants. Following remission, optimisation was performed by increasing the ADA dosing interval. Comparison between optimised and non-optimised group was performed. Results Ocular remission was achieved in 65 (86.6%) patients after a median ADA duration of 63–12 months. ADA was optimised in 23 cases. In the remaining 42 ADA was maintained at 40 mg/sc/2 weeks. No baseline differences were found at ADA onset between the optimised and non-optimised groups. Ocular outcomes were similar after a mean ±S.D. follow-up of 34.7±13.3 and 26±21.3 months in the both groups (table 1). Adverse effects were seen in non-optimised group (lymphoma, pneumonia, local reaction and bacteremia). Mean ADA treatment costs were lower in the optimised vs non-optimised group (6101.25 €/patient/year vs 12339.48). Conclusions ADA optimisation in BD uveitis refractory to conventional therapy is effective, safe and cost-effective. References [1] Calvo-Rio V, Blanco R, Beltran E, et al.
