Assessment and management of ulcerative colitis in children.

The incidence of ulcerative colitis in school-age children in most parts of Europe has been steady at 1.5-2.0 per 100,000 children per year for the last 20-30 years. In comparison to adults, abdominal pain is a relatively frequent presenting symptom in children in addition to rectal bleeding, bloody diarrhoea or diarrhoea. Distribution of disease in children is generally more extensive (ratio rectal:left sided:extensive 25:30:45). There are remarkably few clinical trials of therapy in children and reasons for this are discussed. Subjective indices of disease severity and activity are unreliable in children. Objective measures such as endoscopy are of value to define the extent of ulceration and histopathological features; a test of gut protein loss using whole gut lavage gives an objective index of disease activity. Principles of medical management in children are generally the same as in adults with the additional need for scrupulous attention to nutrition and growth, and psychological factors. Reassuring results of a review of the health status of young adults who had developed ulcerative colitis in childhood are presented. Twenty-four of 27 considered themselves fully fit although nine of the patients had a permanent ileostomy.
