[Incidence of Helicobacter pylori infections in patients with duodenogastric reflux].

The purpose of the work was a comparison of the incidence of Helicobacter pylori (HP) infections in persons with dyspeptic symptoms of non-ulcer dyspepsia (NUD) character in relation to the presence or absence of duodenogastric reflux (DGR). The study included 80 patients aged from 17 to 80 years, 21 males and 59 females. In all studied patients endoscopy of upper digestive tract segment was performed with biopsy specimen taking for microbiological investigations. From each patient two biopsy specimens were taken from the prepyloric part and the fundus. The specimens were subjected to a microbiological analysis using the rapid urease test, culturing, and direct preparation. The presence of duodenogastric reflux was evaluated during endoscopy. In persons with diagnosed NUD and duodenogastric reflux, lower incidence of HP infections was found than in patients with the same diagnosis but without the reflux.
