Application of a stool antigen test to evaluate the burden of Helicobacter pylori infection in dyspepsia patients

Helicobacter pylori (HP) is causally associated with peptic ulcer disease and gastric carcinoma. Determination of the prevalence of HP infection in dyspepsia patients′ in particular geographical area is imperative for the appropriate management of dyspepsia. HP antigen detection in stool is a noninvasive diagnostic test of HP infection. This prospective study was conducted to find out the prevalence of HP infection based on stool antigen testing in dyspeptic patients who had also undergone upper gastrointestinal (GI) endoscopy. This study highlights the high prevalence of HP infection in dyspeptic Indian patients, particularly males, and emphasizes the growing importance of the bacterium causing infection among children. We also found HP stool antigen testing to be superior to upper GI endoscopy for detecting HP infection. Hence, we recommend initial testing for HP stool antigen in dyspeptic patients before initiating treatment and before carrying out any invasive procedure such as endoscopy.
