Coexistence of Helicobacter pylori and Intestinal Parasitosis in Children with Chronic Abdominal Pain.

Objective: The aim of this study was to determine the incidence of coinfection with Helicobacter pylori and intestinal parasitosis in children with chronic abdominal pain (CAP) and to investigate the common risk factors in the development of both infections.

Methods: Ninety patients with CAP were enrolled in this study. Blood samples of each case were screened for human preformed IgG (HpIgG) antibodies, and stool samples were tested for HpSA and also examined for intestinal parasites by direct wet-mount, formalin-ethyl-acetate concentration, and Trichrome staining procedures. Cellophane tape test was used for Enterobius vermicularis. Children tested positive for HpIgG and/or HpSA were accepted as H. pylori positive. The risk factors were compared with a questionnaire.

Results: The incidence of Giardia intestinalis was 14.8% in the H. pylori-positive group and was found to be statistically higher than that in the H. pylori-negative group (1.6%). The positivity rates of H. pylori were found to be statistically higher in children attending school and using drinking water from taps. The incidences of parasitosis were significantly higher in children with a low maternal education level and with a history of parasitosis treatment in the family.

Conclusion: The most common etiologies of CAP in children are H. pylori infection and intestinal parasitosis. İmprovement of hygienic conditions would be beneficial in preventing both infections.
