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

Women with a HbA1C ≥ 6.5% （group one） were instructed on diet and daily self-monitoring of blood glucose. Women with a HbA1C between 5.7%-6.4% （group two） were offered testing or daily self-monitoring of blood glucose. Women with a HbA1C 〈 5.7% （group three） were tested at 24-28 wk. Patients were tested for GDM using the two step testing and Carpenter and Coustan values as cutoffs. Medication was started if patients failed to meet glycemic goals of fasting ≤ 95 mg/dL （5.3 mmol/L） and 2 h postprandial ≤ 120 mg/dL （6.7 mmol/L）.RESULTS： In group one （n = 16）, 15/16 （95%） re-quired medication to achieve euglycemia. The mean gestational age at which medication was required was early at 14 ± 6 wk. Postpartum, 14/16 patients （87%） remained diabetic. Group two contained 82 patients. Sixty-sixpatients （80%） were given a diagnosis of GDM and 52 patients （64%） required medication. The mean gestational age at which medication was started in group two was 20 ± 7.8 wk. There were 205 patients in group three, 18 patients （8.7%） were diagnosed with GDM and 13 patients （6%） required medication. In comparison to group three, patients in group one were 220 times more likely to require medication （95%CI： 26.9- 〉 999, P 〈 0.0001）. Patients in group two were 26 times more likely to require medication （95%CI： 12.5-54.3, P 〈 0.0001）.展开更多
