Crohn's disease and ulcerative colitis, the two main types of chronic inflammatory bowel disease, are multifactorial conditions of unknown aetiology. A susceptibility locus for Crohn's disease has been mapped to chromosome 16. Here we have used a positional-cloning strategy, based on linkage analysis followed by linkage disequilibrium mapping, to identify(More)
In the West, the incidence and prevalence of inflammatory bowel diseases has increased in the past 50 years, up to 8-14/100,000 and 120-200/100,000 persons, respectively, for ulcerative colitis (UC) and 6-15/100,000 and 50-200/100,000 persons, respectively, for Crohn's disease (CD). Studies of migrant populations and populations of developing countries(More)
OBJECTIVE The aim of this work was to assess the quality of life (QoL) of patients with Crohn's disease (CD) prospectively over 1 yr and to determine factors of influence. METHODS A total of 231 CD patients were included. At month 0 (M0), M3, M6, M9, and M12, patients were given a validated QoL questionnaire (self-administered) to fill in and a clinical(More)
BACKGROUND & AIMS The natural history of pediatric Crohn's disease and risk factors necessitating surgery have not been thoroughly described. METHODS In a geographically derived incidence cohort diagnosed from 1988 to 2002, we identified 404 Crohn's disease patients (ages, 0-17 years at diagnosis) with a follow-up time >or=2 years. RESULTS Median(More)
BACKGROUND Crohn's disease incidence rates have stabilised in industrialised countries since the 1980s. Conversely, a continuing increase in childhood-onset Crohn's disease incidence has been reported. AIM To confirm trends in inflammatory bowel disease (IBD) incidence in northern France over an extended time period (1988-2007) with a focus on(More)
There were no data concerning the incidence of inflammatory bowel disease (IBD) in France. The aim of this study was to investigate the incidence of Crohn's disease and ulcerative colitis in northern France. This prospective population based study was realised through the gastroenterologists of the region Nord-Pas de Calais and the Somme Department. Each(More)
Elevated antibody levels against the yeast Saccharomyces cerevisiae have been reported in sera from patients with Crohn's disease and not with ulcerative colitis. The aim of the study was to identify the nature of the epitopes supporting this antibody response. Whole cells from different S. cerevisiae strains were selected in immunofluorescence assay for(More)
BACKGROUND Tioguanine (TG) is an antimetabolite which may be regarded as an alternative to azathioprine (AZA)/mercaptopurine (MP) in patients with inflammatory bowel diseases. AIMS : To evaluate the tolerance and efficacy of TG in patients with Crohn's disease, intolerant or resistant to AZA/MP. METHODS An open prospective study was made on Crohn's(More)
BACKGROUND & AIMS Familial aggregation argues for genetic susceptibility to Crohn's disease. The aim of this study was to compare the age of onset and the clinical features of Crohn's disease between patients with familial disease and those with sporadic disease and investigate the concordance for disease location and type among relatives with Crohn's(More)
BACKGROUND Parenteral nutrition (PN) is still widely preferred to enteral nutrition (EN) in malnourished patients undergoing allogeneic stem-cell transplantation (allo-SCT) after myeloablative conditioning (MAC). The purpose was to determine whether EN improves early outcome after MAC allo-SCT. METHODS Early outcome was prospectively assessed in patients(More)
