[Helicobacter pylori detection by polymerase chain reaction in gastric juice and its correlation with the histology...

HP infection is involved in the pathogenesis of several gastroduodenal diseases, as type B chronic gastritis, duodenal and gastric ulcer, MALT lymphoma and gastric cancer. The recent availability of molecular techniques, specifically the PCR, allow us to detect very low amounts of the bacterium. The aim of the study is to evaluate the presence of HP in gastric juice by PCR technique and to correlate this findings with histology (Giemsa) of gastric mucosa. Gastric juice PCR positive findings were found in 10/31 (32.3%) HP positive patients at histology. We concluded that HP in gastric juice is possible to detect by molecular techniques. In our study 32.3% of the patients showed the presence of HP in gastric juice.
