Corticosteroids are used in patients with refractory celiac disease. In order to minimize theirsystemic side effects, we assessed the role of a locally active sustained release corticosteroid withminimal systemic bioavailability in patients with refractory celiac disease in an open labelednoncontrolled study.
Patients who received budesonide for refractory celiac disease were classified according to whetherthey were primarily or secondarily unresponsive to the diet, and whether they had a polyclonal(type I) or clonal (type II) expansion of intraepithelial lymphocytes. The response to budesonide wasassessed globally and by reduction in bowel movements.
Patients (N = 29, 72% female) received budesonide for a mean of 6.7 ± 8.5 months, 5 patients(18%) had type II disease (clonal T-cell population); 76% responded to the medication, 55%completely. Response occurred when budesonide was used alone or with oral corticosteroidsand/or azathioprine. There was an objective improvement in the number of bowel movements inthose that responded. Response occurred in those with either primary or secondary refractorydisease and in those with type II disease, irrespective of the presence of microscopic colitis (N = 7).
There was no improvement in the duodenal biopsy over the study period and there were no sideeffects of budesonide.
