Clinically, determination of insulin resistance is important for diabetic patients. We evaluated the relationship among 20/(fasting C-peptide × fasting plasma glucose), HOMA-IR and QUICKI indices in type 2 diabetic patients. The study included 40 patients with type 2 diabetes. Patients divided into three groups based on their medication: metformin, metformin + glibenclamide and metfor-min + glitazone. Fasting blood sugar, and lipid profile were measured by enzymatic method, serum insulin, and C-peptide were measured by ELISA method. Insulin resistance was calculated by using of 20/(fasting C-peptide × fasting plasma glucose), HOMA-IR and QUICKI indices. There was no significant relationship between 20/(fasting C-peptide × fasting plasma glucose) index and other parameters in all studied groups except QUICKI in metformin group showed a significant correlation with 20/(fasting C-peptide × fasting plasma glucose) index (r = 0.56 and p = 0.03). There was a significant correlation between HOMA-IR and QUICKI indices in all studied groups. There was no significant relationship between 20/(fasting C-peptide × fasting plasma glucose) index with other clinical parameters. On the other hand, our data strongly suggested a significant correlation between HOMA-IR and QUICKI indices in studied subjects with type 2 diabetes.
