Serum Gastrin Level and Pepsinogen I/II Ratio as Biomarker of Helicocater Pylosri Chronic Gastritis
To find out biomarker as diagnostic tool of H. Pylori chronic gastritiswho fulfilled the inclusion and exclusion criteria. The diagnosis of H. Pylori chronic gastritis was based on histopathological examination and PCR with ure C primer of the gastric biopsy specimen. In addition, we also performed the examination of serum gastrin, pepsinogen (PG) I and PG (Pepsinogen) II level. By using analysis of receiver operating characteristic (ROC), an optimal cut off point of serum gastrin, PGI and PGII level as well as PGI/PGII ratio was determined. Analysis of bivariate logistic regression was used to determine the involved independent variables and possibilities as biomarkers. Significance level was determined by p value 5.89 pmol/L and PGI/PGII ratio≤13.6 can be utilized as biomarkers of H. Pylori chronic gastritis.
