Objective Atrophic gastritis may affect circulating ghrelin levels and, indirectly, body mass index. The aim of this study was to investigate the relationship between atrophic gastritis, focusing on autoimmune atrophic gastritis and advanced stages of atrophic gastritis, serum ghrelin levels and BMI. Methods Sixty-three patients, of whom 18 had autoimmune atrophic gastritis, 27 non-autoimmune antrum and corpus atrophic gastritis, and 18 non-atrophic gastritis or antrum-limited atrophic gastritis (control group) were assessed. All participants underwent endoscopy with multiple gastric biopsies. Atrophic gastritis was diagnosed by histology, classified according to the Updated Sydney System and staged by the Operative Link on Gastritis Assessment (OLGA) Classification. Total serum ghrelin, body weight and height were measured. Results Compared with control patients (144.6 ± 111 pg/ml), mean serum level of total ghrelin was higher in patients with autoimmune atrophic gastritis (226.08 ± 243.03 pg/ml, P = 0.65) and lower in those with both antrum and corpus atrophic gastritis (74.51 ± 37.38 pg/ml, P = 0.12), although differences were not statistically significant. Serum ghrelin decreased in patients with advanced OLGA stages of atrophic gastritis. In non-obese patients BMI was significantly lower in those with both antrum and corpus atrophic gastritis than in control patients (23.1 ± 1.8 vs. 24.5 ± 1.6, P = 0.01), also after adjustment for age and sex (P = 0.02); BMI was positively correlated with serum total ghrelin (r = 0.51, P < 0.001). Conclusion Advanced stages of atrophic gastritis, but not autoimmune atrophic gastritis, seem to be associated with lower serum levels of ghrelin and lower BMI. In non-obese patients, BMI was positively correlated with total serum ghrelin.
