Hemostasis and fibrinolysis factors in first-degree relatives of patients with Type 2 diabetes without hypertension.
First-degree relatives of type 2 diabetic patients with or without a family history of hypertension are at increased risk for cardiovascular diseases. The aim of this study was to verify some possible hemostatic alterations in first-degree relatives of type 2 diabetic, normotensive and hypertensive patients. In 78 non-diabetic, normotensive first-degree relatives of type 2 diabetic patients (47 without a family history of hypertension and 31 with a family history of hypertension) and in 36 normoglycemic, normotensive subjects with no family history of hypertension, we evaluated plasma levels of fasting glucose and insulin, tissue-type plasminogen activator (t-PA), plasminogen activator-inhibitor (PAI-1), D-dimer (DD) and prothrombin fragment 1 + 2 (F1+2). Insulin resistance, calculated by the HOMA model, and plasma levels of t-PA and PAI-1 were significantly higher in relatives of diabetics compared to controls. As far as the thrombin activation indexes are concerned, we detected a significant increase in DD and F1+2 in relatives of diabetics with hypertension compared to other study subjects. In conclusion, our data indicate that familial predisposition may influence the hemostatic system in first-degree relatives of diabetic and/or hypertensive patients.
