Abstract

Helicobacter pylori is the most frequent cause of chronic active gastritis (CAG), namely the first step for gastric cancer development. When infection is not detected at histology, another test is advised. EndoFaster is novel device that reveal the presence of H. pylori by determining ammonium concentration in the gastric juice during endoscopy. We evaluated whether this test may improve etiological diagnosis in CAG patients. In 595 consecutive patients who underwent upper endoscopy gastric juice was analysed with EndoFaster and standard biopsies were taken. CAG with typical bacteria was detected in 102 (17.1%) patients, and CAG without H. pylori was found in 36 (6.3%) cases. EndoFaster detected the infection in 22 (61.1%) of these patients. Neither ongoing proton pump inhibitor therapy nor previous eradication therapy affect the test accuracy. By using EndoFaster, another test to search for the infection in H. pylori-negative CAG patients may be avoided in more than 60% of cases, impacting on both patients discomfort and health resources use.
