摘要

OBJECTIVE: Atrophic body gastritis (ABG) is common in China. Although histology via endoscopy is an efficient and reliable means of diagnosing ABG, it is an invasive procedure. Therefore, in the present study serum pepsinogen (PG) was used as a biomarker to develop a novel noninvasive test as the first option for screening of ABG in certain groups of Chinese.METHODS: The study population consisted of 81 selected dyspeptic patients (mean age, 64.8 +- 0.7 years; M:F, 43:38) who underwent diagnostic gastro-scopy. At least four biopsy specimens were taken from the antrum and corpus of the stomach (two specimens from each site) for histological diagnosis. Blood samples for ELISA assays of serum pepsinogen I (PGI), pepsinogen II (PGII) and IgG antibodies against Heli-cobacter pylori (Hp IgG) were drawn after endoscopy. Cut-off points were calculated using receiver operating curves (ROC).
