The effects of HMG CoA reductase inhibitor PRAVASTATIN on plasma lipoprotein levels, lipid transfer protein (LTP) activity and lecithin cholesterol acyltransferase (LCAT) activity were investigated in 20 patients with heterozygous familial hypercholesterolemia. Plasma total cholesterol decreased from 299.2±45.2 to 245.9±45.1 (mean±SD in mg/dl) (p<0.0001), low density lipoprotein (LDL) cholesterol from 221.1±47.6 to 164.9±48.1 (p<0.0001) and LDL-triglycerides from 38.0±10.2 to 30.2±8.8 (p<0.0001). High density lipoprotein (HDL) cholesterol increased from 60.1±13.9 to 63.1±17.0 (p=0.0264). The HDL-cholesterol: HDL-triglycerides ratio increased from 3.91±1.14 to 4.91±1.65 (p=0.0029). Lipid transfer protein (LTP) activity (as% of transferred cholesteryl ester (CE)) decreased from 4.68±2.47 to 3.70±2.31 (p=0.0024) and LCAT activity decreased from 113.1±29.9 (U/L) to 97.0±22.7. There was a negative correlation between LTP/LCAT ratio and HDL-C levels. These results suggested that the changes in plasma HDL-cholesterol concentrations during treatment with pravastatin may be related to the decreases in LTP and LCAT activity due to this drug.
