Changes induced by gemfibrozil on lipidic, coagulative and fibrinolytic pattern in patients with type IV...

A short term open study (90 days) was carried out with Gemfibrozil in patients (n = 10) suffering from type IV hyperlipoproteinemia. For the whole observation period (120 days) the patients followed a standard diet. Every 30 days the following parameters were checked: total cholesterol, serum triglycerides, HDL-C and its fractions (HDL2-C and HDL3-C), apolipoprotein A1 and B, glucose, fibrinogen, plasminogen, euglobulin lysis time, antithrombin III, alpha-2-antiplasmin and PTT. The administration of the drug caused a reduction of serum triglycerides by 39.5%, an increase of HDL-C by 16.2% together with a significant increase of cholesterol bound to HDL2 (+27.6%). A significant increase was also noticed for the mean levels of apolipoprotein A1 (+19.8%), confirming thus the antidislipidemic effect of the drug. Significant reductions were also found in the mean levels of fibrinogen and alpha-2-antiplasmin together with a return to normality of mean values of antithrombin III and of the euglobulin lysis time. The effect on the lipid, haemocoagulative and fibrinolytic parameters shows that the administration of Gemfibrozil causes favourable changes both on the hyperlipoproteinemic pattern and on the thrombophilic state present in these patients.
