['The postprandial lipid metabolism in metabolic syndrome patients is disturbed and may add to the increased cardiovascular risk in these patients. It is not known whether postprandial high density lipoprotein-cholesterol (HDL-c) metabolism is also affected and whether this can be influenced by statin and/or ezetimibe treatment.', 'Prospective, randomized, double blind, crossover trial comparing simvastatin 80 mg with simvastatin/ezetimibe 10 mg/10 mg treatment for 6 weeks on postprandial HDL-c metabolism in 15, nonsmoking, male, obese metabolic syndrome patients (Adult Treatment Panel III, ATPIII). Only study medication was allowed. HDL-c concentrations, cholesteryl ester transfer (CET), CET protein (CETP) mass and adiponectin were measured before and after oral fat loading. ClinicalTrials.gov NCT00189085.', 'Plasma HDL-c levels remained stable during continuous fasting following an overnight fast. Pre-fat load HDL-c concentrations without treatment, after simvastatin and simvastatin/ezetimibe treatment were 1.15 +/- 0.04, 1.16 +/- 0.05 and 1.11 +/- 0.04 mmol/l. Fat load induced a 11% drop in HDL-c plasma levels; 1.02 +/- 0.05 mmol/l (P < 0.001) which was not affected by either therapy. Triglyceride levels during fat load were similar after both treatments. Total CET increased from 9.73 +/- 0.70 to 12.20 +/- 0.67 nmol/ml/h (P = 0.004). Four hours after fat loading CETP mass was increased while adiponectin levels were decreased, irrespective of treatment.'] Does lipid-lowering therapy affect the postprandial drop in high density lipoprotein-cholesterol ( HDL-c ) plasma levels in obese men with metabolic syndrome : a randomized double blind crossover trial?
