Helicobacter pylori infection in various groups of patients studied, estimated by 14C-urea breath test
Abstract:
The aim of this study was the detection of helicobacter pylori (HP) infection and estimation of the clinical validity and the accuracy of the 14C-urea breath test in the groups of patients studied. A total of 248 patients with gastric diseases were examined. There were 38 patients with gastric ulcer, 41 with duodenal ulcer, 43 with gastroduodenitis erosiva, 26 with hiatus hernia, 36 with gastric carcinoma and 64 patients with gastritis. There were 103 true positive (TP), 139 true negative (TN), 4 false negative (FN) and 2 false positive (FP) patients. There was no significant difference in the incidence of the HP infection between the groups of patients studied (p > 0.05). Sensitivity of the method was 96.3%, specificity 98.6%, positive predictive value 98.1%, negative predictive value 97.2% and accuracy 97.6%. Our results point out that the method is very accurate for the detection of HP infection.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
