Abstract :
Background: Helicobacter pylori is the responsible for chronic infection in the human stomach. Approximately half of the world population colonized or/and infected by this organism. H. pylori can increase the pH of the stomach lumen by urease producing and secretion. In this situation pathogenic intestinal protozoa can cross through stomach easily and cause disease. The aim of this study was to evaluate the relationship between H. pylori infection and intestinal parasitic infections in patients of Ilam city.
Materials and Methods: Following stool samples collection during 2013 in patients with abdominal pain in Ilam, Iran. H. pylori infection was investigated based on stool antigen analysis (HPSA) by enzyme-linked immunosorbent assay (ELISA) method in patients who had recurrent abdominal pain. Stool specimens were examined using the direct examination and the spontaneous sedimentation method for detecting the trophozoite and cyst of parasites.
Results: In this study, we found 65 patients with H. pylori infection. Out of these 65 patients, the percentage of patients with positive results for Giardia lamblia was 30.7% and for Entamoebahistolytica/dispar was 12.3%.
Conclusion: The results of this study suggest that H. pylori infection may provide favorable conditions for giardiasis infection; however, this presumption needs further studies with larger sample size.
