Clinical Dilemmas for the Diagnosis and Treatment of Helicobacter pylori Infection in Children: From Guideline to Practice.

Helicobacter pylori infection is often acquired in early childhood. While most infected children remain asymptomatic, H. pylori can cause chronic gastritis, gastric ulceration, and, in the long term, gastric cancer. This article aimed to review different diagnostic and treatment options and discuss the challenges associated with applying the current guidelines in the real world. Relevant articles published from 2015 to August 2023 in the English language in PubMed and Medline electronic databases were extracted using subject headings and keywords of interest to the topic. References of interest in the selected articles were also considered. Invasive and noninvasive diagnostic tests have advantages but also disadvantages and limitations according to the clinical setting and age of the child. Guidelines recommend not performing diagnostic testing in children with long-lasting or recurrent abdominal complaints or cases of a family history of severe disease caused by H. pylori. However, parents regularly consult with the explicit demand to test for H. pylori because of them or a close family member experiencing severe gastric disease caused by H. pylori. In some situations, it may be challenging for the healthcare professional to stick to evidence-based guidelines and not consider "patient-centered care," with the risk of putting a trustful relationship in danger. Physicians may find it challenging not to perform diagnostic tests for H. pylori and prescribe eradication treatment in specific clinical settings when maintaining a trusting patient-physician relationship by applying this "patient-centered care" method when evidence-based guidelines recommend differently.
