title: [Helicobacter pylori infection diagnosis in dyspeptic patients from the City of San Luis, Argentina, using invasive methods].
abstract: In this study we present a relationship between different gastroduodenal pathologies and Helicobacter pylori infection. We used four diagnosis invasive methods for H. pylori infection: urease test (UT), histopathology (H), Gram stain (G) and culture (C). The upper gastrointestinal endoscopy of 300 dyspeptic patients showed that 71.6% had erosive congestive gastropathies, 13.6% had duodenopathies, 5.6% had gastric ulcer, 6.3% had duodenal ulcer and 2.6% had probable gastric neoplasia. We also correlated the data of water intake source with the pathologies. The percentage of infected patients with H. pylori was determined using: a) two simultaneous reference tests (UT and H), 54.3%, b) each test UT = 55.0%, H = 59.0%, G = 51.3%, and C = 43.0%. Sex, age and the source of water ingested did not show statistically significant differences.
