摘      要：AIM To investigate the relationship between plasma ghrelin level, Helicobacter pylori(H. pylori) infection status and the severity of atrophy in hemodialysis *** One hundred eights patients who received hemodialysis and 13 non-hemodialysis H. pylori-negative controlsunderwent gastroduodenoscopy to evaluate the severity of gastric atrophy. Serum levels of pepsinogen(PG) were measured as serum markers of gastric atrophy. H. pylori infection was evaluated by anti-H. pylori IgG antibody, rapid urease test and culture test. We classified H. pylori infection status as non-infection, present infection and past infection. In addition, plasma acyl-ghrelin and desacyl-ghrelin levels were measured by enzyme-linked immunosorbent assay. RESULTS Infection rate of H. pylori was 45.4%(49/108). Acylghrelin level in the non-infection group(39.4 ± 23.0 fmol/ml) was significantly higher than in the past(23.4 ± 19.9 fmol/ml, P = 0.005) and present infection groups(19.5 ± 14.0 fmol/ml, P 0.001). Furthermore, desacyl-ghrelin level in the non-infection group(353.2 ± 190.2 fmol/ml) was significantly higher than those in the past(234.9 ± 137.5 fmol/ml, P = 0.008) and present infection groups(211.8 ± 124.2 fmol/ml, P 0.001). Acyl-ghrelin was positively correlated with the PG Ⅰ level and PG Ⅰ/Ⅱ ratio(|R| = 0.484, P 0.001 and |R| = 0.403, P 0.001, respectively). Both ghrelins were significantly decreased in accordance with the progress of endoscopic atrophy(both P 0.001) and acyl-ghrelin was significantly lower in patients with mild, moderate and severe atrophy(24.5 ± 23.1 fmol/ml, 20.2 ± 14.9 fmol/ml and 18.3 ± 11.8 fmol/ml) than in those with non-atrophy(39.4 ± 22.2 fmol/ml, P = 0.039, P = 0.002 and P 0.001, respectively).CONCLUSION In hemodialysis patients, plasma ghrelin level was associated with the endoscopic and serological severity of atrophy related to H. pylori infection.
