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

Detailed Description:

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.
