Statins do have modest affects on HDL, increasing concentrations by 5% to 10%, providing a secondary benefit to this therapy beyond LDL reduction. The effect of torcetrapib is dose-dependent; for example, increasing the dose from 10 mg to 120 mg twice daily is associated with an almost 90% CETP inhibition and a greater rise in HDL. 365(24):2255-67. In persons with multiple (2+) risk factors and 10-year risk of equal to or less than 20%, the LDL goal is < 130 mg/dL, while the non-HDL goal is < 160 mg/dL. 2011 Dec 15. 1986 Nov 7. [Medline].

Dose-related effects of repeated ETC-216 (recombinant apolipoprotein A-I Milano/1-palmitoyl-2-oleoyl phosphatidylcholine complexes) administrations on rabbit lipid-rich soft plaques: in vivo assessment by intravascular ultrasound and magnetic resonance imaging. It may be proatherogenic if the VLDL-LDL cholesteryl ester is taken up by arterial macrophages. 2011 Jun 10. Homozygotes have only preβ-1 HDL present in their plasma, while heterozygotes lack large α-1 and α-2 HDL particles, normal preβ-1 HDL, and only 50% of normal cellular cholesterol efflux.

[3, 4, 5, 6, 29], The basic purpose of the management of HA and related lipid abnormalities is to reduce the risk of atherosclerosis, which is the main mechanism of increased morbidity and mortality. [39]. Executive Summary of the Third Report of the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III). Familial hypoalphalipoproteinemias. Tangier disease is a familial HDL deficiency characterized by enlarged orange tonsils, mild hepatosplenomegaly, corneal opacification, and a marked reduction of serum HDL-C and LDL-C as well as mild hypertriglyceridemia. Familial HDL deficiency characterized by hypercatabolism of mature apoA-I but not proapoA-I. Plasma high density lipoproteins. Metabolic and Molecular Bases of Inherited Disease. [43, 44, 45].

Grundy SM, Cleeman JI, Merz CN, et al. FEBS Lett. 110(2):227-39. [Medline]. People in the study had a protein in their HDL, the aforementioned apo A-I Milano, that seemed to be better at stimulating the removal of cholesterol from plaques than was HDL containing the normal protein, called apo A-I. Patrice Wending. Furthermore, signs and symptoms of Familial HDL deficiency may vary on an individual basis for each patient. Available at http://www.cardiosource.com/clinicaltrials/trial.asp?trialID=486. [30, 31], A small study in 2004 involving the CETP inhibitor torcetrapib showed that the drug markedly increased HDL levels and decreased LDL levels when taken alone and also when taken in combination with a statin. 63(18):1907-45.

GILMORE N. O'NEILL, MASON W. FREEMAN, in Peripheral Neuropathy (Fourth Edition), 2005, Macrophages and fibroblasts from TD and FHA patients demonstrate a significant defect in lipid-poor apo A-I–stimulated cholesterol and phospholipid efflux.13,30,84,102 As a result, cholesteryl esters accumulate in membrane free droplets. At 12 months follow-up, patients who received torcetrapib demonstrated a mean increase of 72.1% in HDL cholesterol and a mean decrease of 24.9% in LDL cholesterol, as well as a mean decrease of 9% in TGs compared with baseline (all P< .001 vs atorvastatin-only patients). 2500032-overview 8th ed. 2003 Nov 5.

Circulation 101, 2446–2448. The document also reported that there are several causes of low HDL cholesterol levels and that a number of these—including type II diabetes, overweight, obesity, elevated triglycerides (TGs), and a lack of physical activity—are associated with insulin resistance. The protein content should be approximately 15% of total energy intake. Figure 2. The investigation showed that the atherosclerosis in the coronary vessel wall could be modified in a much shorter time than anticipated, ie, within 5-6 weeks. Treatment for isolated low HDL cholesterol is provided mainly to patients with CHD and CHD risk equivalents. Such patients can have high ratios of total cholesterol to HDL-C (e.g., >10) despite having a normal plasma cholesterol level. Familial hypoalphalipoproteinemia is defined as an HDL cholesterol level below the 10th percentile without a secondary cause and associated with a family history of low HDL levels.
