The effect of Helicobacter pylori eradication on functional dyspepsia in Turkish children

BackgroundThe aim of this study was to evaluate the effect of Helicobacter pylori (H.pylori) eradication on dyspepsia symptom scores in children with functional dyspepsia (FD). Materials and MethodsOne hundred and fifty functional dyspeptic children (ages 8-18years, mean: 13.32.84years; 30% male) were enrolled to this prospective study. Upper gastrointestinal endoscopy was performed on all patients, and the samples from the gastric antrum and corpus were obtained for the existence of H.pylori. (13)Carbon-urea breath test was performed to evaluate the eradication therapy's efficacy. The symptoms were assessed at first visit and at the 8th week and 16th week. ResultsForty-nine (33%) children were in the H.pylori-positive group, and 101 (67%) children were in the H.pylori-negative group. Dyspepsia symptom scores improved at 8th week in both groups (P<.05). Helicobacter pylori was eradicated in 30 patients (61%), while in the H.pylori-eradicated group, all dyspepsia symptoms' scores decreased, and in the H.pylori-uneradicated group, only three symptoms' scores decreased. Symptom scores were lower in H.pylori-eradicated group than H.pylori-uneradicated group. ConclusionsAlthough the tests used for the diagnosis of H.pylori in functional dyspeptic patients increased the cost of health care, the dyspepsia symptom scores decreased with the eradication therapy in a high prevalence community. The findings may differ in low prevalence communities where the diagnostic tests for H.pylori infection are not recommended in children in the absence of alarm signs or symptoms.
