Ezetimibe is the first cholesterol absorption inhibitor, a novel class of lipopenic drugs that inhibit intestinal absorption of biliary and dietary cholesterol. From a pathophysiological point of view, combining complementary drugs that act on different cholesterol metabolism pathways is particularly interesting. This interest has been confirmed in clinical studies combining ezetimibe and statins, which inhibit cholesterol synthesis in the liver.

Methods And Results: We tested the hypothesis that carriers of the -516T allele, who may display consistent elevation in plasma cholesterol over their lifetime, may present more extensive atherosclerotic disease than noncarriers. Genotyping of the apoB 516 C/T promoter polymorphism was performed in 326 subjects at low cardiovascular risk.

Unlabelled: A spectrum of disease from myalgia to rhabdomyolysis exists as classic side-effect of lipid-lowering treatment (LLT). While myopathy has generated considerable interest, mild musculo-skeletal symptoms are poorly assessed.
Objective: To report on the muscular side-effects of LLT with a particular focus on the overlooked milder ones.
Objective: The combination of LDL apheresis with high doses of a potent hepatic hydroxymethylglutaryl coenzyme A reductase inhibitor, such as atorvastatin, has been the best therapy available for the prevention of cardiovascular disease in patients with homozygous familial hypercholesterolemia (HFH). However, some concerns have been made about the effect of atorvastatin on HDL cholesterol levels in these patients.
Methods And Results: HDL cholesterol levels were determined bimonthly over the course of 2 years of treatment with high-dose atorvastatin in genotypically defined HFH patients either receptor-defective (n=6) or receptor-negative (n=6) under long-term treatment with LDL apheresis.
Objectives: In severe type IV hypertriglyceridemia (triglyceride levels >10 g/l), it is yet unknown whether lipoprotein lipase (LPL) differs according to the presence or not of diabetes.
Methods: We compared LPL activity and the presence of four common variants in the LPL gene (Asp 9 Asn (exon 2), Gly 188 Glu (exon 5), Asn 291 Ser (exon 6) and Ser 447 Ter (exon 9)) in a group of 34 patients of whom 17 presented diabetes mellitus.
Results: Maximum triglyceride, cholesterol levels and distribution of apolipoprotein E phenotypes did not differ between the two subgroups.
Objective: To improve the preoperative selection for operation of patients with solitary thyroid nodules.
Design: Prospective cohort study.
Setting: University hospital, France.
