title: Plasma prekallikrein, kallikrein inhibitors, kininogen and lipids during gemfibrozil treatment in type II dyslipidaemia.
abstract: The effects of gemfibrozil on plasma prekallikrein, kallikrein inhibitors, kininogen and plasma lipids were investigated in 31 male subjects having either type IIA or IIB dyslipidaemia. During gemfibrozil use, plasma prekallikrein and kininogen were increased significantly while kallikrein inhibitors increased only slightly. Total cholesterol and triglycerides decreased while HDL cholesterol was increased. Changes in prekallikrein and HDL cholesterol were correlated, whereas no other significant correlations between changes in lipid and kinin parameters were seen. The observed changes in prekallikrein and kininogen possibly indicate a shift in the thrombo-haemorrhagic balance in favour for increased fibrinolysis. If so, the effects of gemfibrozil in prevention and management of atherosclerosis would not be solely due to correlation of the dyslipidaemia but also to protection against the accelerated coagulation tendency seen in type II dyslipidaemia.
