The Relation betweenHelicobacter pyloriInfection and Acute Bacterial Diarrhea in Children

Abstract

Background.H. pyloriinfection leads to chronic gastritis in both children and adults. But recently, there are arising theories of its protective effect in diarrheal diseases.Aim. To explore the prevalence ofH. pyloriinfection in children with bacterial diarrhea and compare it with healthy controls.Patients and Methods. Two matched groups consisted of 122 consecutive children, aged 24–72 months old, with acute bacterial diarrhea, who had Shigellosis (N=68) and Salmonellosis (N=54) as patients group and 204 healthy asymptomatic children as control group enrolled in this study.Results. The prevalence ofH. pyloriinfection in healthy control children was significantly higher than in patients group, (odds ratio = 3.6, 95% CI: 1.33–9.5,P=0.007). In our study, only 2/54Salmonellainfected patients and 3/68 of Shigellosis had evidence ofH. pyloriinfection, while normal control children had 27/204 infected individuals.Conclusion.H. pyloriinfection may play a protective role against bacterial diarrhea in children. So it is important to consider all of the positive and negative aspects ofH. pyloriinfection before its eradication.
