This cross sectional study was conducted from October 2023 to March 2024, on 170 patients
attending Gastroenterology outpatient clinic in Benha University hospital and aimed to investigate
the association of intestinal parasites with H. pylori infection and the associated symptoms.
Stool samples were collected and examined within an hour by: direct wet smear technique,
concentration method and Modified Ziehl-Neelsen stain. A rapid chromatographic immuno- assay
was used for the qualitative detection of H. pylori copro-antigens in stool. All patients with
aged ranged from 20 to 60 years old, were 73 males (42.94%) and 97 females (57.06%) presenting
with gastrointestinal manifestations.
The results showed that 103 (60.59%) patients were positive H. pylori copro-antigen in stool
and 24 (14.12%) had different intestinal parasites. There was a significant association between
intestinal parasites and H. pylori infection (P= 0.0001). Besides, intestinal parasites were associated
with H. pylori were in (18.45%) of positive patients, and in (7.46%) of H. pylori negative
patients.
There was significant difference for different types of intestinal parasites as regarding H. pylori
infection (P=0.007). Entamoeba histolytica 11 (10.68%) were the most frequently detected parasite
in association with H. pylori, followed by Giardia lamblia 5 (4.85%) and Enterobius vermicularis
2 (1.9%).
