BACKGROUND AND AIMS This study evaluates the long-term safety of infliximab in patients with inflammatory bowel disease (IBD) treated with the drug over a 14-year period. METHODS The medical records of 734 patients with IBD treated with infliximab and 666 control patients not treated with infliximab were reviewed for adverse events. The time of onset and(More)
Fecal microbiome variation in the average, healthy population has remained under-investigated. Here, we analyzed two independent, extensively phenotyped cohorts: the Belgian Flemish Gut Flora Project (FGFP; discovery cohort; N = 1106) and the Dutch LifeLines-DEEP study (LLDeep; replication; N = 1135). Integration with global data sets (N combined = 3948)(More)
BACKGROUND AND AIMS Several antibodies have been associated with Crohn's disease and are associated with distinct clinical phenotypes. The aim of this study was to determine whether a panel of new antibodies against bacterial peptides and glycans could help in differentiating inflammatory bowel disease (IBD), and whether they were associated with particular(More)
BACKGROUND & AIMS Clinical presentation at diagnosis and disease course of Crohn's disease (CD) are heterogeneous and variable over time. Early introduction of immunomodulators and/or biologicals might be justified in patients at risk for disease progression, so it is important to identify these patients as soon as possible. We examined the influence of(More)
BACKGROUND Infliximab treatment is effective in 70-80% of patients with refractory luminal and fistulizing Crohn's disease. The effect of infliximab is ascribed to induction of apoptosis. AIM To study whether polymorphisms in apoptosis genes predict the response to infliximab and whether they interact with clinical predictors. METHODS Cohort of 287(More)
Primary sclerosing cholangitis (PSC) is a chronic bile duct disease affecting 2.4-7.5% of individuals with inflammatory bowel disease. We performed a genome-wide association analysis of 2,466,182 SNPs in 715 individuals with PSC and 2,962 controls, followed by replication in 1,025 PSC cases and 2,174 controls. We detected non-HLA associations at rs3197999(More)
BACKGROUND TGR5, the G protein-coupled bile acid receptor 1 (GPBAR1), has been linked to inflammatory pathways as well as bile homeostasis, and could therefore be involved in primary sclerosing cholangitis (PSC) a chronic inflammatory bile duct disease. We aimed to extensively investigate TGR5 sequence variation in PSC, as well as functionally characterize(More)
BACKGROUND The outcome of primary sclerosing cholangitis (PSC) has improved by liver transplantation (LT), but patients often develop malignancies. We analysed morbidity and mortality patterns to define strategies to prevent complications. METHODS Two hundred consecutive patients diagnosed before October 2005 were studied. RESULTS Malignancies developed(More)
BACKGROUND The autophagy pathway has been linked with Crohn's disease (CD) through association of the ATG16L1 and IRGM genes with susceptibility for CD, and also to the Nod2 pathway, involved in CD. Our aim was to investigate polymorphisms in selected autophagy genes for their association with susceptibility to CD. METHODS We prioritized all known human(More)
