METHODS:HbA_(1c) values were determined in 15 patients with compensated liver cirrhosis and in 20 patients with chronic hepatitis using the ion-exchange high performance liquid chromatography and the immunoassay methods. Fructosamine was determined using nitroblue tetrazolium. RESULTS:Forty percent of patients with liver cirrhosis had HbA_(1c) results below the non-diabetic reference range by at least one HbA_(1c)method,while fructosamine results were either within the reference range or elevated.Twenty percent of patients with chronic hepatitis(hepatic fibrosis) had HbA_(1c)results below the non-diabetic reference range by at least one HbA_(1c)method.In patients with chronic hepatitis treated with ribavirin,50% of HbA_(1c)results were below the non-diabetic reference using at least one of the HbA_(1c)methods. CONCLUSION:Only evaluated in context with all liver function parameters as well as a red blood count including reticulocytes,HbA_(1c)results should be used in patients with advanced liver disease.HbA_(1c)and fructosamine measurements should be used with caution when evaluating long-term glucose control in patients with hepatic cirrhosis or in patients with chronic hepatitis and dbavidn treatment.展开更多
