Methods: rhLCAT (ACP-501) was infused intravenously over 1 hour on 3 occasions in a dose optimization phase (0.3, 3.0, and 9.0 mg/kg), then 3.0 or 9.0 mg/kg every 1 to 2 weeks for 7 months in a maintenance phase. 290(17):2322-4. Although these were exciting results, a larger trial employing synthetic HDL infusion therapy is needed. [Medline]. Plasma apo AI concentration is extremely low, with a relative increase in precursors of apo AI. Therefore, no particular treatment recommendations can be made at this juncture. In the ADvicor Versus Other Cholesterol-Modulating Agents Trial Evaluation (ADVOCATE), 315 patients with high LDL (≥160 mg/dL without CAD, or ≥130 mg/dL with CAD) and low HDL (< 45 mg/dL in men, and < 50 mg/dL in women) were randomized to 16 weeks of a combination of niacin/lovastatin versus standard doses of atorvastatin or simvastatin. These patients cannot form HDL, and therefore have a defect in reverse cholesterol transport, whereby cholesterol is mobilized from peripheral sites and returned to the liver. The statin/niacin combination also resulted in a 60-90% reduction in the incidence of major coronary events. Familial Hypoalphalipoproteinemia. The following are recommendations: Patients should reduce their intake of saturated fats to less than 7% of their total calorie (energy) intake. [3, 4, 5, 6] ; lowering LDL levels has been demonstrated to reduce CHD morbidity and mortality in multiple randomized clinical trials. Lamon-Fava S, Postfai B, Diffenderfer M, et al. A severe type of this deficiency … Several novel approaches to increasing HDL cholesterol that have been under investigation include the following: The aforementioned partial CETP inhibitor, torcetrapib, may increase HDL by as much as 46%. In the present guidelines, low HDL cholesterol both modifies the goal for LDL-lowering therapy and is used as a risk factor to estimate 10-year risk for CHD." 40(3):486-94. The Seattle Hypertriglyceridemia Study conducted at the same time with hypertriglyceridemic probands, who did not have clinical atherosclerosis, found no evidence for premature CAD in the FHTG families.110 This was confirmed by a 20-year follow-up study.19 It also is possible that the families termed FHTG in the NHLBI Family Heart Study111 actually had FHA.

A comparison of methods for the estimation of plasma low- and very low-density lipoprotein cholesterol. [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. Two pharmacologic inhibitors of CETP have undergone phase 3 clinical trials: torcetrapib and JTT-705. 1998 Aug 19. HDL is often referred to as "good cholesterol" because high levels of this substance reduce the chances of developing heart and blood vessel (cardiovascular) disease. 48(3):592-9. 1983 Mar 24. Clinical manifestations in patients with Tangier disease. 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. 66(6):1845-56. In homozygotes, plasma HDL is virtually absent and triglyceride levels are often elevated. John D. Brunzell, in Clinical Lipidology, 2009, In 1992, Genest and colleagues proposed that FHA, a disorder with elevated triglyceride and low HDL cholesterol, was a common genetic dyslipidemia associated with premature CAD.106,107 The HDL Atherosclerosis Treatment Study (HATS) selected middle-aged men and women with premature CAD for an intervention study.108 In HATS, 87 men with low HDL selected to not have diabetes or elevated apoB levels were proposed to have FHA.101 These men had normal levels of apoB compared with FCHL.101 In contrast to FHTG, men with FHA had lower plasma apoA-I levels and did not have triglyceride-rich HDL particles as seen in FHTG.

Familial HDL Deficiency This inherited disorder causes a person to have abnormally low levels of HDL (“good”) cholesterol circulating in their system. Stanbury JB, Wyngaarden JB, Fredrickson DS, et al, eds. J Clin Endocrinol Metab. However, mutations in these candidate genes are rare and account for little FHA. Fish eye disease, initially described in two families of Swedish origin, is characterized by the absence of LCAT activity towards HDL only. Obligatory heterozygotes have half the normal plasma HDL-C and apo AI levels. Whenever possible, eliminate medications associated with low HDL cholesterol levels. Overall, fibrates reduce the risk for major coronary events by 25%, whereas currently available data for niacin suggest about a 27% reduction. Medscape Reference Feature Series - Lipid Newsletter. 2008 Mar 18. This disorder is characterized by a genetic predisposition in subjects consuming high-fat, high-cholesterol diets to an increased secretion of apo B-containing lipoproteins and an increased catabolism of apo A-I-containing lipoproteins. Human HDL deficiency (hypoalphalipoproteinemia) defines a group of dyslipidemias characterized by an HDL cholesterol level below the 10th percentile for age- and sex-matched subjects. Eur J Haematol. 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). Brites FD, Bonavita CD, De Geitere C, et al. J Am Coll Cardiol. Reproduced with permission from Komuro, R., et al. The NCEP has recommended a therapeutic lifestyle-change diet, which should be incorporated in the treatment of all patients. The glitazones, which are PPAR (peroxisome proliferator-activated receptor) agonists, act by lowering free fatty acid (FFA) and TG levels and by raising HDL. Ordovas, in Encyclopedia of Human Nutrition (Third Edition), 2013.
