OBJECTIVE: To test the hypothesis that remission of Behçet's disease (BD) in patients with severe vital organ involvement is maintained after withdrawal of successful anti-tumor necrosis factor (anti-TNF) treatment. METHODS: This single-center, retrospective, longitudinal outcomes study focused on consecutive patients with disease refractory to treatment with conventional immunosuppressant agents who responded to add-on long-term anti-TNF treatment that was subsequently discontinued. The end point was the proportion of patients remaining in complete remission for at least 3 years after withdrawal of anti-TNF treatment. RESULTS: In our BD cohort comprising 87 patients, 29 were eligible for analysis. All of these patients had disease that was refractory to conventional immunosuppressive therapy and had received successful anti-TNF treatment for a median of 2 years (interquartile range [IQR] 1.1-2.0) before treatment discontinuation. Of these patients, 12 (41%) achieved the study end point. The remaining 17 patients experienced a relapse within 1 year (IQR 0.6-1.5) after discontinuation. Re-treatment with anti-TNF was safe and effective in 14 (82%) of 17 patients; so far, 4 of these patients also achieved the study end point. Overall, 16 patients have remained in complete remission (median 6.5 years [IQR 5.5-8]). Ten of these patients are in drug-free remission (treated with anti-TNF agents, mainly for sight-threatening disease), and 6 are in azathioprine-maintained remission (treated with anti-TNF agents for ocular, intestinal, or central nervous system involvement). Notably, patients in drug-free remission were significantly younger and had a significantly shorter duration of BD when anti-TNF treatment was initiated compared to patients receiving azathioprine maintenance treatment. CONCLUSION: Drug-free, long-term remission after withdrawal of successful anti-TNF treatment is feasible in patients with severe BD. Because an anti-TNF agent-induced "cure" cannot be differentiated from spontaneous remission by natural history, prospective studies should examine whether anti-TNF agents should be used as first-line treatment for the induction of remission in every patient with vital organ involvement.
