Aim: To investigate genetic differences between Crohn's disease (CD) patients with a sustained remission vs relapsers after discontinuing infliximab while in corticosteroid-free remission.
Methods: Forty-eight CD patients received infliximab and were in full corticosteroid-free clinical remission but then discontinued infliximab for reasons other than a loss of response, were identified by review of an electronic database and charts. Infliximab-associated remission was defined as corticosteroid-free plus normalization of clinical disease activity [CD activity index (CDAI) < 150] during follow-up visits based on physician global assessments.
Objective: To determine whether the clinical efficacy and safety of infliximab in diverse clinical referral practices was similar to that seen in the randomized, controlled clinical trials.
Methods: Data were gathered from a review of charts of 109 consecutive patients with inflammatory and/or fistulizing Crohn's disease who received infliximab infusions. Responses were recorded based on the physician's global clinical assessment and classified as complete, partial or nonresponse.
