title: [The relationship of gastrin, pepsinogen, and Helicobacter pylori in erosive reflux esophagitis].
abstract: OBJECTIVE
  Helicobacter pylori (H. pylori) infection is known as a major cause of atrophic gastritis and is associated with serum gastrin, pepsinogen, and gastric acid secretion. There is still a controversial association between gastroesophageal reflux disease and H. pylori infection. This study was designed to investigate the relationship among serum gastrin, pepsinogen, and H. pylori infection in the erosive reflux esophagitis (ERD) patients.
  
  
  METHODS
  Patients who were diagnosed as ERD by one gastroenterologist at the Kangnam St. Mary's hospital were prospectively enrolled. The persons without ERD in the control group were matched for age and sex. We examined the gastrin, pepsinogen I (PG I), PG II, PG I/II ratio, and H. pylori infection.
  
  
  RESULTS
  Forty five patients were enrolled in ERD group and 66 persons in control group. The H. pylori infection rate in ERD group was lower than that in the control group (11.1% vs. 43.9%, p<0.001). PG I/II ratio in ERD group was higher than that in the control group (7.0+/-3.1 vs. 5.3+/-2.6, p=0.003). The PG II (p=0.016) and gastrin (p=0.029) in ERD group were lower than those in the control group. BMI in ERD group was higher than that in the control group (24.5 vs. 23.1 kg/m2, p=0.013).
  
  
  CONCLUSIONS
  The H. pylori infection rate in ERD group was lower and PG I/II ratio was higher than that in the control group. Reflux esophagitis is thought to be reversely associated with the atrophy of gastric mucosa.
