MARTINEZ ECHAVARRIA, María Teresa; FERREIRA CAPOTE, Raúl  e  GONZALEZ TORRES, Maximino. Helicobacter pylori in patients with different gastroduodenal diseases. Rev cubana med [online]. 2008, vol.47, n.4. ISSN 0034-7523.

The role played by Helicobacter pylori in the development of different digestive diseases has been widely studied and discussed. The presence of this bacterium in biopsy samples obtained by endoscopy was studied. 69 patients with duodenal ulcer, gastric ulcer, chronic gastritis and dyspepsia were investigated. The diagnoses of gastric ulcer and chronic gastritis were histologically confirmed. 27 duodenal ulcers, 12 gastric ulcers, 24 chronic gastritis and 6 dyspepsias were analyzed. The presence of Helicobacter pylori was detected through the amplification of a fragment of the Ure A gene by polymerase chain reaction in 100 % of the duodenal ulcers, in 100 % of the gastric ulcers, in 83 % of the dyspepsias and in 92 % of chronic gastritis, for a total prevalence of 95.7 %.
