title: Helicobacter pylori infection in childhood: results of management with ranitidine bismuth citrate plus amoxicillin and tinidazole.
abstract: OBJECTIVE
  To verify whether a triple therapy bismuth citrate plus amoxicillin and tinidazole eradicates H. pylori infection in pediatric patients.
  
  
  METHODS
  Fifty children (30 females; mean age 12.4 +/- 1.1 years, range 10-15 years) suffering from upper abdominal complaints and Helicobacter pylori (H. pylori)-associated gastroduodenal disease were treated with a 4 week course of ranitidine bismuth citrate (400 mg, twice daily) plus oral tinidazole (20 mg/kg) and amoxicillin (50 mg/kg) for the first 2 weeks.
  
  
  RESULTS
  The endoscopic diagnoses were: esophagitis (seven cases), gastritis (six cases), gastroduodenitis (43 cases), duodenitis (one case), gastric ulcer (two cases) and duodenal ulcer (13 cases). Helicobacter pylori was eradicated in 40 (80%) patients and clinical improvement was noticed in 39 (78%) of symptomatic subjects. Duodenal ulcers were healed in all the children, but lymphoid nodular hyperplasia was persistent in all patients, independent of the H. pylori status. The potentially drug-related adverse events (blackening of the tongue, six patients; diarrhea, one patient; disturbance of taste, two patients) were registered in seven (14%) patients and dark stools were observed in 48 (96%) patients. No children withdrew from the study because of either side-effects or clinical laboratory changes. No patient had toxic levels of blood bismuth (values ranged between 2.1 and 5.4 microg/L, mean value 3.4 +/- 1.04 microg/L).
  
  
  CONCLUSIONS
  Findings suggest that the present treatment regimen is effective enough in the resolution of H. pylori-associated peptic ulcer disease of childhood.
