Abstract

We previously found a relationship between plasminogen activator inhibitor type-1 and lipoprotein(a) in non-insulin-dependent diabetes mellitus and hypothesized that this could be due to a compensatory mechanism able to lower the risk of hypofibrinolysis found in type II diabetes mellitus. The aims of the present study were: (1) to confirm the association between plasminogen activator inhibitor type-1 and lipoprotein(a) in a different group of non-insulin-dependent diabetes mellitus patients and (2) to investigate whether the association could be related to diabetic complications. Other vascular risk factors able to influence fibrinolytic parameters such as glycemia, obesity, hypertension, dyslipidemia, and oxidative stress were also considered. Sixty-six non-insulin-dependent diabetes mellitus patients without diabetic complications (48 men, 18 women), 45 non-insulin-dependent diabetes mellitus patients with complications (21 men, 24 women), and 31 control subjects (17 men, 14 women) were studied. Plasma concentrations of lipoprotein(a), plasminogen activator inhibitor type-1 antigen and activity, and the main parameters of lipo- and glycometabolic balance were determined. Antioxidant defense was assayed as oxygen radical absorbance capacity of serum. Statistically significant differences among controls and the two diabetic groups were found for fasting glucose, cholesterol, triglycerides, and oxygen radical absorbance capacity of serum, while no statistically significant differences were evident for plasminogen activator inhibitor type-1 antigen and activity and lipoprotein(a). Regression analysis of log plasminogen activator inhibitor type-1/lipoprotein(a) showed a significant correlation only in diabetic patients without complications (r = -0.57, P
