RESUMO
INTRODUCTION: Behçet's disease (BD) is a systemic, inflammatory disorder affecting multiple organ systems, frequently treated with TNF-α blocking agents, as infliximab and adalimumab. Insights about long-term use of adalimumab are lacking. Therefore, we conducted a study into the long-term efficacy and safety of adalimumab in BD. METHODS: A retrospective cohort study from patients with BD treated with adalimumab in the Erasmus Medical Center was performed. Patients included were at least 18 years of age, diagnosed according to ISG criteria, and uninterruptedly used adalimumab for at least 36 months. RESULTS: In a population of 39 BD patients using adalimumab, 29 patients persisted treatment >36 months (range 37-206 months). Indications for treatment were uveitis (n = 15) 51.7%, mucocutaneous involvement (n = 9) 31%, arthritis (n = 2) 6.9%, intestinal disease (n = 3) 10.3%. Overall, adalimumab decreased the occurrence of flares from 0.64 to 0.17 flares per year and BCVA improved subsequently. Also, a steady decline in BDCAF is reported over the course of at least 5 years. Subsequently, 79% was able to reduce their use of immunosuppressive agents aside from adalimumab. Adverse effects were reported in, (n = 15) 51.7% of which (n = 13) 86.6% were infectious complications. Two of those required inpatient hospital care. CONCLUSION: Our study illustrates durable long-term efficacy of adalimumab treatment in patients with BD. In our patient cohort long-term adalimumab treatment is safe, with a low incidence of serious adverse events.
