title: [Prevention of duodenal ulcer recurrence by the use of anti H2. Comparison of continuous long-term and seasonal therapy].
abstract: The Authors have assessed the incidence of ulcer recidivation in patients with cicatrized bulbar ulcers following anti H2 treatment using two maintenance therapy protocols: 1) 400 mg/day of cimetidine in a single evening dose for 1 year (continuous therapy); 2) the same dose of cimetidine administered at the same time but only for 4 months a year (February-March and September-October) (seasonal therapy). Ninety patients with cicatrized ulcers which had been diagnosed using endoscopy were randomly assigned to the two treatment protocols. Protocols were followed for a least one year with endoscopic controls every 6 months. There were no significant differences between continuous and seasonal therapy in relation to the recurrence of duodenal ulcers (Log Rank test p less than 0.05). Cox's proportional hazard model was used to assess the effect of the two treatment protocols on ulcer recurrence eliminating the influence of sex, age and smoking; it was seen that only smoking influenced the incidence of recidivation (p less than 0.05). These results suggest that seasonal maintenance therapy with anti H2 is as efficacious as continuous therapy in preventing the recurrence of ulcers.
