Co-infection of Helicobacter pylori with Blastocystis and Giardia intestinalis in children with gastrointestinal symptoms

This study was conducted to investigate the relationship between Helicobacter pylori infection with Blastocystis and Giardia intestinalis infections in children

A total of 300 pediatric patients (0-17 years of age), including 155 patients who were determined to be H. pylori positive and 145 patients who were determined to be H. pylori negative, were included in the study. Stool samples of all patients included in the study were analyzed by the nativ-Lugol method

Among H. pylori-positive patients, 3.2% (5/155) had G. intestinalis and 6.4% (10/155) had Blastocystis. In H. pylori negative patients, G. intestinalis was detected in 3.4% (5/145) and Blastocystis in 6.2% (9/145). No statistically significant difference was found between H. pylori and G. intestinalis or Blastocystis positivity.

The incidence of G. intestinalis and Blastocystis infections in children is independent of H. pylori infection
