Rapid weight gain in infliximab treated Crohn's disease patients is sustained over time: real-life data over 12 months.

Background: Infliximab (IFX) is used in active Crohn's disease for induction and maintenance of remission. There are scanty data on weight gain in IBD-patients under anti-TNF treatment. We investigated changes in weight and blood chemistry in anti-TNF-naïve Crohn's disease patients during their first course of IFX.
