Prostaglandin E2 and F2 alpha levels in the duodenal and antral mucosa of non-ulcer dyspeptic and duodenal ulcer patients

In the present study we evaluated the contents of endogenous prostaglandins type E2 and F2 alpha in the antral mucosa, and the type E2 in the duodenal mucosa in a group of thirty non-ulcer dyspeptics in comparison with a group of thirty duodenal ulcer patients. A significantly reduced concentration of duodenal and antral PGE2 was found in ulcer patients as compared with dyspeptic subjects. A significantly increased concentration of antral PGE2 was observed in cases with active superficial antral gastritis, either in dyspeptics or in duodenal ulcer patients, as compared with normal antrum cases. A significantly increased level of PGF2 alpha was found in active superficial gastritis of the dyspeptic group.
