Mucosal and plasma prostaglandin E2 in ulcerative colitis.

Author information

Department of Infectious Diseases, Medical Academy of Bialystok, Poland.



Despite extensive studies, the role of prostaglandins in the course of inflammatory bowel diseases and their possible usefulness as predictive indicators of inflammation, remain largely speculative. The aim of this study was to determine whether mucosal and plasma concentrations of prostaglandin E2 (PGE2) are affected by the clinical course and degree of colonic injury in patients with ulcerative colitis.


PGE2 concentration was measured with an enzyme immunoassay (EIA) in biopsies of rectal mucosa and in the plasma of 38 patients with ulcerative colitis and 12 controls. Patients were divided into groups according to mild or severe clinical course of the disease, and with respect to scored endoscopical picture.


Ulcerative colitis resulted in an increase of mucosal and plasma concentrations of PGE2, that was significantly elevated in patients with a severe clinical course of the disease. These concentrations increased depending on degree of mucosal injury. A significant, positive correlation with endoscopical score regarding plasma and mucosal PGE2 concentration, as well as between them, was found.


Plasma and mucosal PGE2 rise simultaneously with degree of colonic injury. Because of a good correlation with mucosal injury and PGE2 content, measurement of plasma PGE2 could be considered as a possible surrogate marker of bowel inflammation.
