Résumé

Background & aims: The management of intra-abdominal abscesses complicating Crohn's disease (CD) is challenging and surgery with delayed intestinal resection is often recommended. The aims of this study were to estimate the success rate of adalimumab (ADA) in CD patients with an intra-abdominal abscess resolved without surgery, and to identify predictive factors for success.Methods: A multicenter, prospective study was conducted in biologic-naïve CD patients with resolved intra-abdominal abscess treated with ADA with a two-year follow-up. The primary endpoint was ADA failure at W24 defined as a need for steroids after W12, intestinal resection, abscess recurrence, and clinical relapse. Secondary post-hoc endpoint was the long-term success defined as the survival without abscess relapse or intestinal resection at W104. The factors associated with ADA failure at W24 and W104 were identified using a logistic and a cox regression, respectively.Results: From April 2013 to December 2017, 190 patients from 27 GETAID centers were screened, and 117 were included in the analysis. Fifty-eight (50%) patients were male and the median age at baseline was 28 years. At W24, 87 (74%, 95%CI: 65.5-82.0, n=117) patients achieved ADA success. Among the 30 patients with ADA failure, 15 underwent surgery. At W104, the survival rate without abscess recurrence or surgery was 72·9% (95%CI: 62.1-79.8, n=109). Abscess drainage was significantly associated with ADA failure at W24 (OR=4.18; 95%CI: 1.06-16.5; p=0.043). Disease duration (HR=1.32, 95%CI: 1.09-1.59, p=0.008), abscess drainage (HR=5.59, 95%CI: 2.21-14.15, p=0.001), and inflammatory changes in mesenteric fat (HR=0.4, 95%CI: 0.17-0.94, p=0.046) were significantly associated with ADA failure at W104.Conclusion: Provided that the abscess was carefully managed before initiating medical treatment, this study showed the high efficacy of ADA in the short and long term in biologic-naïve patients with CD complicated by an intra-abdominal abscess.
