Abstract
Helicobacter pylori infection is acquired primarily during childhood and carries a significant lifetime risk for morbidity. In developing countries, approximately 70% of children are infected with the bacterium by their 15th birthday. In the United States, the rate of H pylori infection among children varies widely--approximately 10% of all 10-year-olds are infected; however, this figure is substantially higher among populations of immigrant children and children born of recent immigrants to the United States. H pylori transmission is primarily "person-to-person" via fecal-oral, gastric-oral, or oral-oral routes, with evidence suggesting contaminated water as a potential source of infection. Risk factors for infection in childhood include an infected family member, having > or =2 siblings, crowded living conditions, lower socioeconomic means, and attendance at a daycare facility. The natural history of H pylori infection includes an increased lifetime risk for peptic ulcer and gastric adenocarcinoma or lymphoma. In children and adults who develop H pylori-related peptic ulcer, cure of the infection is associated with a <5% rate of ulcer recurrence. The ideal mode of H pylori detection among children is unclear--currently available serology and whole blood tests are unreliable, while the urea breath test and stool antigen tests have not been studied adequately. Children with confirmed H pylori-related peptic ulcer disease, iron-deficiency (sideropenic) anemia, or a first-degree relative with gastric cancer should be treated for the infection using 1 of 3 available 10- to 14-day triple therapy regimens recommended by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.
