BACKGROUND
Glucose intolerance and diabetes mellitus are frequently observed in chronic liver disease. However, the causal relationships between these two are difficult to prove. Chronic hepatitis B infection, which is prevalent in Korea, is thought to be a good model to study the natural history of abnormal glucose metabolism in chronic liver disease because many patients with chronic hepatitis B infection eventually progress to liver cirrhosis. METHODS: In order to evaluate glucose metabolism in chronic hepatitis B infection, we did intravenous glucose tolerance test in patients with chronic hepatitis B and age, sex and body mass index matched controls and compared the first phase insulin response and glucose disappearance rates between 2 groups. RESULTS: Patients with chronic hepatitis B showed lower glucose disappearance rate and higher plasma insulin and C-peptide area (0-10min after iv glucose) than controls. Patients with decreased glucose disappearance rate had higher AST level and decreased plasma C-peptide area (0-10min). CONCLUSION: Most of the patients with chronic hepatits B infection is associated with insulin resistance and compensatory increase in the first phase insulin secretion. Inadequate insulin secretion may contribute to decreased glucose disappearance rate in these patients. |
