[Parenteral symptoms and intestinal complications in children with inflammatory bowel diseases in relation to card15 mutation].
OBJECTIVE
Was evaluation of the incidence of parenteral symptoms and complications in children with inflammatory bowel disease and their analysis in relation to the examined mutations of CARD15 gene.


METHODS
The study involved 38 children with Crohn's disease, aged from 5 to18 years (median14) and 40 children with ulcerative colitis, aged from 6 to18 years (median14). The control group included 23 children, aged from 4 to 18 years (median15), with functional disorders of the alimentary tract resulting from lactose intolerance. In all the examined patients as well as in the control group, mutations R702W, G908R and L1007fs of the CARD15 gene were determined, according to the protocol described by Tukel et al.


RESULTS
Parenteral symptoms, in the group of children with Crohn's disease, manifested as arthritis and erythema nodosum, were observed in 7 patients (18.4%), whereas in the group with ulcerative colitis they presented - in 4 children (10%). Intestinal complications in the form of stenosis, fistula, abscess and gastrointestinal bleeding were the most frequently observed changes in children with Crohn's disease (n=15; 39,5%). Parenteral symptoms were statistically significantly more frequent in children with Crohn's disease and with at least one mutation of CARD15 gene. Intestinal complications statistically appeared more often in children with Crohn's disease and mutation L1007fs.


CONCLUSIONS
1. Parenteral symptoms and intestinal complications occurred more frequently in the group of children with Crohn's disease, in comparison with the children with ulcerative colitis. 2. We observed a relation between parenteral symptoms and at least one mutation of CARD15 gene and a relation between intestinal complications and L1007fs mutation.
