Summary

Background  Some reports have suggested that infliximab may induce obstructive symptoms and, although there is no firm evidence, it is usually contra-indicated in-patients with Crohn’s disease (CD) and strictures.

Aims  To evaluate the effect of infliximab on symptomatic strictures of the small intestine in CD and to identify predictive factors of clinical response.

Methods  This retrospective study included symptomatic patients treated with infliximab after conventional treatment had failed. The short-term (week 8) and long-term results were classified according to predefined criteria as complete, partial response, or failure.

Results  Before infliximab, 18 patients had complete obstruction or intermittent chronic abdominal pain. Fourteen patients were treated by corticosteroids and 13 received immunosuppressive drugs. At week 8, complete, partial response and failure were observed in 10, 7 and 1 patients, respectively. Fourteen patients continued maintenance infliximab treatment after week 8. During the most recent evaluation (median follow-up: 18 months), 8 patients were on maintenance infliximab treatment; only eight were still on prednisone; there were five complete responses, 10 partial responses and three failures. Initiating prednisone or increasing its dosage was the only factor associated with a short-term complete response.

Conclusions  Infliximab may be effective in patients with symptomatic strictures from CD, and should be tested before considering surgery.
