The association of histologic gastritis with gastroesophageal reflux and delayed gastric emptying.
The aims of this study were to: 1) investigate the incidence of histologic gastritis in patients with gastroesophageal reflux (GER); 2) ascertain if gastritis in GER patients could be correlated with impaired gastric emptying; and 3) determine if the presence of histologic antral gastritis correlated with other parameters of esophageal and gastric function. Twenty-three GER patients, mean age 53.3 years (range 28-68 years) with subjective and objective evidence for GER; and 20 normal subjects (13 males and seven females), mean age 28.7 years (range 19-46 years), underwent upper gastrointestinal endoscopy. Antral biopsies obtained from the greater curvature were graded as: 0 = normal; 1 = chronic gastritis; 2 = chronic active gastritis; and 3 = chronic atrophic gastritis. All patients underwent a gastric emptying study using an isotope-labeled semisolid meal. Eighteen of the 23 GER patients (78%) had histologic gastritis compared to two (10%) of the normals. No subject had endoscopic evidence of gastritis. Gradings of histologic gastritis were significantly (p less than 0.05) correlated with delayed gastric emptying. Twelve GER patients had severe gastritis (grades 2 or 3) and their gastric emptying, 79.7% +/- 5.8 (mean +/- S.E.M.) retention of isotope at 90 minutes after the meal, was significantly slower (p less than 0.01) than the 11 GER patients with either grade 0 or 1 gastritis, 56.1% +/- 5.9 retention, or the normal subjects, 51.8% +/- 1.7. We conclude that: 1) histologic gastritis is associated with GER disease; and 2) slowing of gastric emptying can be significantly correlated with increased severity of histologic gastritis in GER patients.
