Abstract

Among 92 patients with chronic gastritis we conducted a synchronous diagnosis of the Helicobacter pylori (H. pylori) infection using a culture and a serological test (IFP), in conjunction with breath and urine tests involving 14C-urea (BTU-C14 and UTU-C14). The infection was confirmed by isolation in 71 persons (77.2%), the presence of specific IgG in the blood serum was found in 75 (81.5%). In comparison, the BTU-C14 indicated a group of 77 people (83.7%) as infected, and the UTU-C14 a group of 76 (82.6%). In order to determine the diagnostic value (sensitivity, specificity and efficiency) of the latter tests, the results were compared with those of the culture and of the serological tests. It was found that the BTU-C14 test used showed a 100% sensitivity, a 89.5% specificity and a 97.9% efficiency. The UTU-C14 test showed a 100.0% sensitivity, a 94.4% specificity and a 98.9% efficiency in the detection of the H. pylori infection.
