The prevalence of Helicobacter pylori positivity in human immunodeficiency virus-infected children.
To investigate the prevalence of Helicobacter pylori infection in pediatric patients infected with the human immunodeficiency virus, we sought to detect the presence of antibodies against this organism in 23 human immunodeficiency virus-infected children of central African ethnic origin by means of a second-generation enzyme-linked immunoassay (ELISA) test for the detection of immunoglobulin G (IgG) antibodies to Helicobacter pylori (Malakit Helicobacter pylori, Biolab, Limal, Belgium). They were compared to an asymptomatic control population matched for age and ethnic origin. Blood samples were taken during routine blood analysis before the monthly administration of intravenous gamma-globulins in the human immunodeficiency virus-infected patients and during preoperative blood analysis in the control population. Despite the fact that most human immunodeficiency virus-infected patients had IgG antibodies against other frequently encountered pathogens, none of them had a positive serology for Helicobacter pylori, compared to 10 of 52 patients (19.2%) in the control population. This difference is statistically significant (p = 0.01).
