Comparison of Serum Trefoil Factor-3 to Endoscopy in Diagnosing Helicobacter Pylori Associated Gastric Ulcer

Helicobacter pylori-associated gastric ulcer (H.pylori-GU) is a serious condition, not only because H.pylori is identified as a grade 1 carcinogen but also because GU is a precancerous condition. Identification and treatment of H.pylori-GU may prevent the sequential progression of dysplasia to carcinoma. Trefoil factor 3 (Tf3) has been implicated in gastric mucosal repair. We compared serum Tf3 to gastric endoscopy in diagnosing H.pylori-GU. The study included eighty patients suffering from H.pylori induced gastritis, forty of which presented with GU. Gastric endoscopy with slide urease test was used to diagnose H.pylori-GU. Serum Tf3 level was determined using an enzyme immunoassay in all patients as well as thirty healthy volunteers. Serum Tf3 showed a significant stepwise decrease among the studied groups. It was significantly lower in patients compared to the control group (p
