Patients with refractory inflammatory bowel disease (ulcerative colitis and Crohn's disease) before and after treatment with infliximab.

Infliximab (IFX) is an effective treatment for Crohn's disease and ulcerative colitis (UC) patients not responding to standard therapy. 30-40% of patients do not improve and response is often incomplete. The aim of this study is to identify mucosal gene signatures predictive of response to IFX using high-density oligonucleotide arrays. Forty-three patients with inflammatory bowel disease, 19 with Crohn's colitis and 24 with UC, undergo a colonoscopy with biopsies before and 4 to 6 weeks after the first IFX treatment. Response to IFX is defined as endoscopic and histologic healing. Total RNA was isolated from pre-IFX biopsies, labelled and hybridized to Affymetrix HGU133plus2.0 Array. Microarray data were analyzed using Bioconductor software. Quantitative real time RT-PCR and immunohistochemistry were used to confirm microarray data.
