RESUMO
AIMS: To investigate the situations of abnormal glucose metabolism and dysfunction of pancreatic islet beta cells in subjects of chronic hepatitis B (CHB) with cirrhosis. METHODS: 106 hepatitis B virus (HBV) positive subjects with liver cirrhosis as well as with different grade of Child-Pugh and 37 healthy subjects were included in this study. The oral glucose tolerance test (OGTT), C-peptide and insulin release test were detected. Plasma glucose and insulin levels were analyzed periodically for 2 h after oral glucose loading. RESULTS: There was no significant difference in the level of fasting plasma glucose and C-peptide between cirrhosis group and control group (P>0.05). The levels of OGTT 2 h glucose, insulin and C peptide were significantly higher in cirrhosis group than control group (P<0.01). Peak plasma glucose levels were obtained at 60 min in normal group and cirrhosis group. The peak insulin and C-peptide response occurred at 60 min in normal group, whereas it was delayed to 120 min in cirrhosis group. There was a significant difference between two groups in the pattern of plasma glucose levels at corresponding time points (P<0.05). The OGTT 2 h glucose and insulin levels were positively correlated with Child-Pugh Score (r1 = 0.389, r2 = 0.508, P<0.01). CONCLUSION: These findings implied that there was a certain degree of insulin resistance and abnormal glucose metabolism in the patients with liver cirrhosis.
