Abstract

This prospective randomized double-blind study examined whether sulphydryl-containing agents stimulate the healing and prevent the recurrence of duodenal ulceration in man. To this end, DL-methionine methyl sulphonium chloride (MMSC, 500 mg four times daily) or DL-cysteine (200 mg four times daily) were orally administered with cimetidine. Symptomatic endoscopy-proven duodenal ulcer patients who were smokers and social drinkers were randomized to receive for 8 weeks cimetidine (400 mg b.d.), cimetidine (400 mg b.d.) with MMSC, or cimetidine (400 mg b.d.) with cysteine. These patients were then kept on their respective oral regimens (except for cimetidine which was changed to 400 mg at bedtime) for 1 year (maintenance) and followed up for another. After 8 weeks of treatment, the ulceration healed in 65 patients (74%) given cimetidine alone but in all the patients given MMSC (n = 87) or cysteine (n = 86) with cimetidine (p less than 0.01). During the maintenance year, 15 patients (29%) given cimetidine at night relapsed. Addition of MMSC or cysteine to cimetidine incurred a significantly (p less than 0.001) lower relapse rate. During the year following maintenance therapy, the relapse rate in the group that had been previously treated with cimetidine alone (63%, n = 51) was significantly (p less than 0.001) higher than that in the groups previously treated with MMSC and cimetidine (6%, n = 67) or cysteine with cimetidine (6%, n = 64). The results suggest that sulphydryl-containing agents stimulate the healing and protect against the recurrence of duodenal ulceration.
