ABSTRACT The objective of this study was to determine gender differences in pediatric patients with Crohn disease.
We conducted a retrospective cohort study of 989 consecutive pediatric patients (566 boys, 423 girls) who had Crohn disease (aged 0 to 17 years at diagnosis) by using the Pediatric IBD Consortium Registry. Uniform data were analyzed to compare the presentation and course of disease according to gender.
Median follow-up time was 2.8 years. Mean +/- SD age at diagnosis of inflammatory bowel disease (11.5 +/- 3.8 years) did not differ by gender. Compared with boys, girls had a higher prevalence of mouth sores at symptom onset and a higher prevalence of hypoalbuminemia at the time of diagnosis. Location of disease did not differ by gender. A higher proportion of girls had abnormal anti-outer membrane porin of Escherichia coli levels compared with boys. Girls were at increased risk for erythema nodosum/pyoderma gangrenosum and decreased risk for growth failure compared with boys.
Girls appear to have an overall more severe course of disease; however, boys are at increased risk for developing growth failure. Disease course and the impact of disease severity on growth according to gender in pediatric Crohn disease require prospective study.

    ABSTRACT: Crohn's disease in childhood causes linear growth retardation, which has a substantial effect on management of this disease. By contrast, growth is rarely a problem in children presenting with ulcerative colitis. Depending on how growth failure is defined, approximately one-third of children with Crohn's disease have growth retardation at diagnosis. Although corticosteroids can suppress growth, decreased height at diagnosis demonstrates that this finding is a consequence of the disease and not merely an adverse effect of treatment. Both inflammation and undernutrition contribute to decreased height velocity. Increased cytokine production acts both on the hepatic expression of insulin-like growth factor 1 (IGF-1) and at chondrocytes of the growth plates of long bones. Growth hormone insensitivity caused by deranged immune function is a major mechanism in growth retardation. Resolution of inflammation is the cornerstone of treatment, but current studies on growth hormone and IGF-1 might yield therapies for those children whose inflammation is refractory to treatment.

    ABSTRACT: Crohn's disease (CD) and ulcerative colitis (UC) are the two main forms of inflammatory bowel disease (IBD) with both overlapping and distinct clinical, pathological and biomolecular features. It has been suggested that pediatric IBD is a distinct disease entity, with probably different disease subtypes.The aim of this study is to review and summarize the evolution of the current concept of pediatric IBD. The results of this review reinforce the idea that pediatric CD and UC may be further classified in various clinicopathologic entities. For clinicians and pathologists convenience, practical algorithms for the distinction of the various subphenotypes of pediatric IBD are also provided.

    ABSTRACT: Gender differences in paediatric patients with inflammatory bowel disease (IBD) are frequently reported as a secondary outcome and the results are divergent. To assess gender differences by analysing data collected within the Swiss IBD cohort study database since 2008, related to children with IBD, using the Montreal classification for a systematic approach.
