[Gastrointestinal giardiasis associated with Helicobacter pylori].

The study involved 160 patients with chronic cholecystitis associated with chronic gastroduodenitis. Obtaining biopsy specimens of gastric mucosa and bile samples allowed to compare the microbial picture and the morphological structure of gastric mucosa in the same patient, to identify patterns of colonization of the stomach, 12 duodenal ulcer and gall bladder various microorganisms. At cytological examination was detected in the gall bladder G. lamblia in 47.5 +/- 3.95% of cases in the stomach--in 29.09 +/- 6.12% of cases. The frequency of H. pylori detection in biopsy of gastric mucosa amounted to 98.18 +/- 1.8% of cases, in 12-duodenum--93.75 +/- 1.9%, in the gall bladder--to 54.38 +/- 3.94%, in the bile duct--in 54.38 +/- 3.94%. It was found strict association between the detection of H. pylori and G. lamblia in the stomach--100% of H. pylori-infection combined with giardiasis. Morphological changes of gastric mucosa in the form of lymphoid infiltration detected mainly in the mixed-infection H. pylori and G. lamblia.
