title: Failure of cimetidine to prevent gastroduodenal ulceration and bleeding after renal transplantation.
abstract: Treatment of renal transplant patients with the H2-antagonist cimetidine has previously been assumed to be of reasonable prophylactic value in controlling the incidence of the postoperative complications of gastric or duodenal ulceration. We attempted to evaluate the performance of the drug in a controlled trial by treating transplant patients with either cimetidine or a placebo. Of the 59 patients accepted for the trial, four had to be excluded eventually because of irregularities in the administration of the drug and, in on case, nonfatal respiratory failure. Six of 27 from the cimetidine group had erosions or ulcers by the third day after surgery and two more had them by the end of the fourth week. Three of 28 placebo patients developed lesions after 3 days and three more developed them after 7 weeks. In the months after transplantation, one cimetidine and two placebo patients developed ulcers. Bleeding occurred three times with cimetidine and twice with the placebo. Renal function was similar in both groups as was the necessity of transplantectomy because of irreversible rejection. We conclude that cimetidine does not lower the incidence of gastroduodenal mucosal lesions and upper gastrointestinal bleeding after renal transplantation, nor does it influence rejection of the allograft.
