Treatment of hemorrhagic gastritis with 15(R)-15 methyl prostaglandin E2: report of a case.
A 19-yr-old male developed severe hemorrhagic gastritis following three abdominal operations. Treatment with intravenous cimetidine and hourly antacids to maintain his gastric pH above 5 failed to affect gastrointestinal bleeding. Also, peripheral venous vasopressin, propantheline bromide, and glucagon were without effect. Total gastrectomy was considered to control his bleeding. However, since a number of prostaglandin analogs prevent gastric lesions produced by many noxious agents (e.g., aspirin, alcohol, strong acid or alkali, etc.) in animals and humans, the patient was treated with 50 micrograms of 15(R)-15 methyl prostaglandin E2 intragastrically every 6 h for 10 days. To epimerize the 15(R) form to the more active 15(S) form, 50-100 ml of 50-mN HCl was placed into the patient's stomach immediately before each dose. Bleeding ceased within 24 h of the onset of 15(R)-15 methyl prostaglandin E2 therapy and did not recur. The prompt response to 15(R)-15 methyl prostaglandin E2 in combination with hourly antacids in this patient with persistent and severe hemorrhagic gastritis suggests a therapeutic effect and the need for a prospective double-blind clinical trial.
