Abstract

Culture is one of the methods used for detecting Helicobacter pylori in the stomach. However, since it is costly, labor-consuming, and in a number of infected subjects gives a false negative result, the procedure is not routinely used. The aim of the study was to analyze some of the factors that may affect the outcome of H. pylori culture from endoscopic gastric mucosal specimens. The study was conducted in a group of 265 subjects. The culture of gastric mucosal specimens was verified by urease test and histological examination. If the culture result was not consistent with one or two verifying tests, an additional two tests were used, i.e. H. pylori antigens in stool samples and anti-H. pylori antibodies in blood serum. In patients infected with H. pylori (at least two positive diagnostic tests), the analysis of factors that may affect the culture outcome revealed that neither age, gender, smoking, history of eradication, endoscopic diagnosis, use of proton pump inhibitors, ultrasonography of the abdomen or chest radiology performed the day before or on the day of gastroscopy, nor preparation for colonoscopy using osmotic fluids 1-2 days prior to gastroscopy had an effect on the culture outcome. Only high activity of gastritis...Continue Reading

Atrophic Gastritis

Atrophic Gastritis is a process where gastric glandular cells are lost and replaced with firbous tissues, as a result of chronic inflammation. Learn more about Atrophic Gastritis here.
