title: [Helicobacter pylori infection in children].
abstract: Helicobacter pylori (Hp) is a pathogen of human gastric mucosa and is considered as the major cause of chronic gastritis and duodenal ulcer disease recurrence. The prevalence rate of Hp infection increases with age and is related to low socioeconomic status in childhood. Childhood appears to be a high-risk period for Hp infection. Clinical and histological features of Hp infection are variable and often moderate in children. This is probably due to both genetic and environmental factors. Abdominal pain is the most frequent symptom and is usually associated with a mild chronic gastritis. Serology, 13C-urea breath test, bacterial culture and histological examination of biopsy specimen can be used for the diagnosis of Hp infection. Eradication of Hp infection is difficult and indications and modalities of treatment need to be specified in children. A better knowledge of epidemiology and natural history of Hp infection in childhood should permit to answer these questions.
