Plasma plasminogen activator inhibitor-1 activity in normoglycemic hypertriglyceridemic north Asian Indian subjects: a preliminary case-control study.

BACKGROUND
Recent evidence suggests that increased activity of plasma plasminogen activator inhibitor-1, an important component of the insulin resistance syndrome, plays a crucial role in the pathogenesis of atherosclerosis.


METHODS AND RESULTS
In this case-control study, relationships between plasma plasminogen activator inhibitor-1 activity, serum triglyceride levels and hyperinsulinemia were explored in 40 non-diabetic patients with primary hypertriglyceridemia (Group 1) and 40 non-diabetic normotriglyceridemic controls (Group 2) matched for potential confounders like smoking and physical activity. Mean values of fasting serum insulin levels were increased in Group 1 (p>0.05). Hyperinsulinemia was observed in 14 (17.5%) individuals in Group 1 and 11 (13.8%) individuals in Group 2. Mean plasma plasminogen activator inhibitor-I activity in Group 1 (9.8+/-8.4 IU) was higher than in Group 2 (7.0+/-7.7 IU), though the difference was not significant (p>0.05). However, when only subjects with elevated levels of plasma plasminogen activator inhibitor-1 activity were taken into account, mean values were significantly higher in Group 1 (p<0.05). The plasma plasminogen activator inhibitor-1 activity was higher in subjects with body mass index >25 in both the groups, significantly so in males (p=0.05). Hyperinsulinemic subjects with a body mass index >25 and raised serum triglyceride levels had higher mean values of plasma plasminogen activator inhibitor-1 activity (18.42+/-11.15 IU) than subjects with similar characteristics and normal triglyceride levels (14.22+/-8.20 IU, p<0.05).


CONCLUSIONS
Though in the current study a trend for hyperinsulinemia and high plasma plasminogen activator inhibitor-1 activity was observed in hypertriglyceridemic subjects, a larger study is needed to achieve significant differences and correlations. Obese male subjects, irrespective of their lipid profile, are at risk for thrombotic events in view of their significantly higher plasma plasminogen activator inhibitor-1 values. Procoagulant tendency is further enhanced if hypertriglyceridemia and hyperinsulinemia are added on to obesity.
