This study evaluated the relation of leptin with glycaemic control and the effect of 14 days of diet, or diet combined with gliclazide, glipizide-GITS or metformin treatment, on leptin concentration in 51 female patients with type 2 diabetes mellitus. Leptin levels were similar both at baseline and after treatment in diabetic and control groups. Diabetic patients with basal fasting plasma glucose (FPG) < 10 mmol/l or with basal postprandial plasma glucose (PPPG) < 13.9 mmol/l had significantly higher leptin levels than diabetic patients with basal FPG > or = 10 mmol/l or with basal PPPG > or = 13.9 mmol/l (19.6+/-8.7 vs. 13.65+/-5.4 microg/l, p < 0.05; and 20.2+/-7.9 vs. 12.9+/-5.2 microg/l, p < 0.05, respectively). Mode of treatment did not influence leptin levels. Delta leptin showed a weak correlation with basal FPG (r = 0.346; p < 0.05), basal and post-treatment PPPG (r = 0.335, p < 0.05 and r = 0.325, p < 0.05, respectively) and a moderate correlation with post-treatment FPG (r = 0.391, p < 0.01). In conclusion, leptin level is not affected by the presence of type 2 diabetes mellitus and by short-term treatment with diet or oral antidiabetic drugs but is directly related to glycaemic control in female patients with type 2 diabetes mellitus.

The influence of the hypoglycemic agent glipizide (0-100 microM) on the rate of gluconeogenesis from lactate, as well as on the levels of fructose 2,6-bisphosphate, has been investigated in hepatocytes isolated from genetically obese (fa/fa) Zucker rats and from their corresponding lean (Fa/-) littermates. As compared to lean rat hepatocytes, liver cells isolated from obese animals showed a lower rate of basal gluconeogenesis (0.9 +/- 0.2 vs 5.4 +/- 0.5 micromol of lactate converted to glucose/g cell x 30 min, n=4) and higher levels of fructose 2,6-bisphosphate (11.5 +/- 1.0 vs 5.9 +/- 0.4 nmol/g cell, n=8-9). In lean rat hepatocytes, the presence of glipizide in the incubation medium caused a dose-dependent inhibition of the rate of lactate conversion to glucose (maximal inhibition=46%; EC50 value=26 microM), and simultaneously raised the cellular content of fructose-2,6-bisphosphate (maximal increment=40%; EC50 value=10 microM). In contrast, in hepatocytes isolated from obese rats, the inhibition of gluconeogenesis and the increment in fructose-2,6-bisphosphate levels elicited by glipizide were significantly reduced (maximal effects of 22 and 13%, respectively). Similarly, the activation of glycogen phosphorylase and the increase in hexose 6-phosphate levels in response to glipizide were less marked in obese rat hepatocytes than in liver cells isolated from lean animals. These results demonstrate that the efficacy of sulfonylureas as inhibitors of hepatic gluconeogenesis is reduced in the genetically obese (fa/fa) Zucker rat.

OBJECTIVES: The study was performed to see that, whether metabolic control and response to treatment in freshly diagnosed patients of type 2 diabetes mellitus is affected by primary pathology (hyperinsulinemia/inappropriate insulin secretion). METHODS: One hundred and eight freshly diagnosed patients of type 2 diabetes mellitus with age range from 30-65 years were followed for a period of three months. The blood glucose, serum triglyceride, and serum insulin levels were determined in each patient. Patients were found to have either higher or normal to low serum insulin values at fasting, and accordingly patients were distributed into two groups; group one (normal to low initial fasting serum insulin level i.e. < or = 30 microU/ml) and group two (high fasting serum insulin level i.e. > or = 30 microU/ml). Each group was further divided into two subgroups A and B. Subgroup A was treated with glipizide and B with metformin. RESULTS: Diabetic patients who had fasting hyperinsulinemia (n = 53, 100%) had blood pressure > or = 140/90 at the time of presentation. Patients who had fasting serum insulin within normal range only 30% (n = 17) had hypertension. Patients of group one had good recovery from hyperglycemia and reduction in triglyceride values when treated with sulphonylurea (subgroup A) as compared to patients treated with biguanide (subgroup B). On the contrary patients of group two showed poor glycemic control, increase in blood pressure and rise in serum triglyceride titre when treated with sulphonylurea (subgroup A) while in the same group biguanide effectively produced euglycemia with normalization of blood pressure and decrease in triglyceride levels (subgroup B). CONCLUSION: Assessment of initial serum insulin levels is helpful guide to decide about the type of oral hypoglycemic agent to be used in freshly diagnosed patients to type 2 diabetes mellitus.
