Abstract

H. pylori infection is one of the most frequent chronic bacterial infections in human beings. Through different pathogenic factors (adhesins, urease, cagA and vacA cytotoxic proteins) it may produce mucosal changes that can be seen in an upper gastrointestinal endoscopy. These changes include, among others, ulcerative lesions, cobblestone mucosa and pallor alternating with erythema. Its favorite targets in children are the gastric antrum and proximal duodenum. This article reviews the endoscopic findings related to H. pylori infection in children and their possible causes and clinical consequences.
