    Abstract:
    AIM OF THE STUDY: To retrospectively evaluate the efficacy, the duration of response, and the tolerance of Remicade in anoperineal Crohn's disease. METHODS: Fifty patients with severe symptomatic and refractory anoperineal Crohn's lesions (38 fistulae and 29 cavitating ulcers and superficial fissures) were treated with 3 intravenous infusions of Remicade (5 mg/kg) at weeks 0, 2 and 6. Efficacy was assessed using Allan's functional score and proctologic examination at 8 weeks (W8) and 24 weeks (W24) after the first infusion. RESULTS: At W8, a response was noted for 71% (27/38) of fistulae and 79% (23/29) of ulcers and fissures. Healing rates were 39% and 49%, respectively. Efficacy of Remicade at W8 did not vary according to sex, number and type of fistulae and other treatments. At W24, 58% (15/26) of patients with fistulae and 63% (10/16) of patients with ulcers or fissures had a response. The response rate at W24 was higher in patients having anoperineal Crohn's lesions for less than one year: 77% vs 32% (P=0.004). Median Allan's score significantly decreased from 3.9 before treatment to 1.7 at W2 (P<0.001), 1.3 at W6 and 0.8 at W8. Median duration of response was 9.5 months (range: 0.5-12.5) after last infusion and was not influenced by associated treatments including immunomodulators. The relapse rate at 1 year was 64% for the responders followed at least one year (n=21). Minor adverse events occurred during 12% of all infusions. Eight patients had an infection, including one pneumonia. Eight patients developed a perineal abscess 16 weeks (range: 4-32) after the first infusion. CONCLUSION: Remicade is rapidly effective and well tolerated in anoperineal Crohn's lesions, but the high relapse rate stresses the need for long term therapeutic strategies in these patients.
