title: Accuracy of serum pepsinogens I and II, gastrin-17 and anti-helicobacter pylori antibodies in histological diagnoses of atrophic gastritis.
abstract: 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.
