OBJECTIVE Atrophic gastritis is defined as a chronic inflammatory process in gastric mucosa leading to loss of glandular cells. It is considered a precancerous condition, thus its early diagnosis is of importance. Although histo-pathologic studies remain as the gold standard of diagnosis, non-invasive methods suitable for screening purposes are being developed. This includes measurement of serum gastric profile. METHODS Two hundred and fifty 250 patients who were planned to undergo upper gastrointestinal endoscopy were randomly selected to be included in this study. Serum levels of pepsinogen I and II, gastrin-17 and anti-Helicobacter pylori (Hp) antibody were measured and the results were compared with that of histopathologic assessment of biopsy specimens obtained during endoscopy. RESULTS IgG anti-Hp, PGII and PGI/PGII ratio showed correlation with age. PGI/PGII ratio showed best sensitivity (96.1%) and negative predictive value (97.7%). PGI has the highest specificity (94.6%), and PGII also had a high negative predictive value (90.7%). IgG anti-Hp showed poor sensitivity and specificity (58.8% and 26.5%, respectively). CONCLUSIONS Pepsinogen I/II ratio appears to be the most suitable single measurement for screening purposes in atrophic gastritis.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
