Diagnostic Accuracy Of Stool Antigen In Diagnosis Of Helicobacter Pylori Infection In Children

Helicobacter pylori is among the most common bacterial infections in humans. Helicobacter pylori is a Gram-negative, S -shaped rod .The most likely mode of transmission is fecal-oral or oral-oral. Helicobacter pylori infection is acquired in early life and continues to have a high prevalence, especially in developing countries. Growing antibiotic-resistant strains necessitate adapted treatments. The majority of children with Helicobacter pylori infection remain asymptomatic, although a percentage of the infected children do develop Helicobacter. pylori-associated diseases. Helicobacter pylori is closely associated with the development of gastritis, gastric or duodenal ulcers. Helicobacter pylori infection can manifest with abdominal pain or vomiting and, less often, refractory iron deficiency anemia or growth retardation. Helicobacter pylori can be associated, though rarely, with chronic autoimmune thrombocytopenia. Anemia, idiopathic thrombocytopenic purpura, short stature, and sudden infant death syndrome (SIDS) have also been reported as possible extra-gastric manifestations of Helicobacter pylori infection . The diagnosis of Helicobacter pylori infection is made histologically by demonstrating the organism in the biopsy specimens. 13 C-urea breath tests and stool antigen tests are reliable noninvasive methods of detecting Helicobacter pylori infection in patients who do not require endoscopic evaluation. However, some guidelines recommend that non-invasive assessment methods are reserved to determine whether Helicobacter pylori has been eradicated not for diagnosis .However Helicobacter pylori-associated gastritis may, however, be an incidental histopathologic finding during upper endoscopy performed for unrelated indications such as the diagnosis of inflammatory bowel disease, or celiac disease.
