title: [Diagnostic methods for Helicobacter pylori infection in children].
abstract: A Helicobacter pylori infection is usually acquired during early childhood. Poor socioeconomic circumstances form an important risk factor for this. An untreated infection may lead to peptic ulceration and, particularly in adults, to gastric cancer and mucosa associated lymphoid tissue (MALT) lymphoma. The gold standard for the diagnosis of H. pylori infection is gastroscopy with histology and culture of biopsy specimens. Non-invasive tests are serology, 13C-urea breath test and stool antigen test. The sensitivity and specificity of serology tests are low in children, but for both the 13C-urea breath test and the stool antigen test the sensitivity and specificity are high. A 'test and treat' approach is advised with due consideration for possible symptoms and the risk for peptic ulcers and gastric cancer at a more advanced age. The treatment results must be evaluated. If necessary, young children can be treated at a later age.
