Prevalence of intestinal parasites and Helicobacter pylori coinfection, and contributing factors among patients with gastrointestinal manifestations at Addis Zemen primary hospital, Northwest Ethiopia

Background The urease-producing Helicobacter pylori increase the likelihood that pathogenic intestinal protozoa will use the stomach's increased hydrogen potential to propagate the disease. Coinfections exacerbate the onset and severity of gastrointestinal symptoms. This study aimed to assess the prevalence of intestinal parasites/Helicobacter pylori coinfection and contributing factors in patients with gastrointestinal symptoms at Addis Zemen Primary Hospital, Northwest Ethiopia. Methods From April to July 2023, patients with gastrointestinal problems participated in a cross-sectional study carried out in a hospital. To collect the clinical and sociodemographic data, a questionnaire was employed. Intestinal parasites and Helicobacter pylori were detected using the saline stool wet mount and Helicobacter pylori stool antigen tests, respectively. SPSS version 20 was used to analyze the data and variables with p-values < 0.05 were considered statistically significant. Result The study included 384 participants in total, of which 47.3% (182/384) were farmers and 50.3% (193/384) were women. Of the study subjects, 69/384 or approximately 18%, had intestinal parasitic infections. In 12% of cases (46/384), Helicobacter pylori were detected. A coinfection of Helicobacter pylori and intestinal parasites was found in 5.5% (21/384) of the subjects. Multiple logistic regression revealed increased risk of coinfection of Helicobacter pylori and intestinal parasites in patients who drink surface water (AOR: 10.7, p = 0.03) family history of Helicobacter pylori (AOR: 3.3, p = 0.024) and those with untrimmed fingers (AOR: 4.9, p = 0.031). Conclusions Giardia lamblia and Entamoeba histolytica/dispar/ moshkovskii/ bangladeshi complex are the most common protozoans that cause coinfection with Helicobacter pylori. Drinking surface water, family history of Helicobacter pylori and untrimmed fingers are the contributing factors to intestinal parasites/Helicobacter pylori coinfection.
