One week treatment for Helicobacter pylori infection.

Helicobacter pylori is associated with primary antral gastritis, duodenal ulceration, and gastric cancer. Current regimens for treating infection in children using bismuth and antibiotics for two to six weeks are cumbersome. The aim of this study was to evaluate a one week course of treatment. All children undergoing endoscopy were assessed for the presence of H pylori by culture, histology, rapid urease test, and 13C urea breath test. Infected children received a one week course of colloidal bismuth subcitrate 480 mg/1.73 m2/day (maximum 120 mg four times a day), combined with metronidazole 20 mg/kg/day (maximum 200 mg three times a day), and clarithromycin 15 mg/kg/day (maximum 250 mg twice a day). To optimise compliance, drugs were dispensed in a 'Redidose' box containing a compartment for each day, and subcompartments marked 'breakfast', 'lunch', 'dinner', and 'bedtime'. Compliance and side effects were assessed immediately after treatment. A urea breath test was performed at least one month after treatment. Twenty two children infected with H pylori were entered into the study; 20 of these took all doses; two children suffered significant side effects (diarrhoea and vomiting). H pylori was eradicated in 21 of the 22 children (95.45%; 95% confidence interval 77% to 100%). This study shows that H pylori infection in children can be cleared by a one week course of treatment.
