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. Role of the estrogen and progestin in hormonal replacement therapy on apolipoprotein A-I kinetics in postmenopausal women. Narrower (1) Hdl Deficiency, Type 2. Whereas phospholipid efflux is abnormal, total cell phospholipid content is not significantly altered.

Funke and colleagues in 1991 reported a 42-year-old German patient with corneal opacification, marked HDL deficiency and apoA-I deficiency, significantly decreased plasma LCAT activity, increased non-HDL-C and TGs, and lack of CVD. Twin bothers living on Tangier Island, Chesapeake Bay, Virginia, suffered from yellow-orange tonsils, hepatosplenomegaly, and neuropathy. levels of paraoxonase, an HDL-associated, antioxidant enzyme, were also increased by 10%. Singh VN. Circulation 101, 2446–2448. [Medline]. 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. FEBS Lett. The apo A-1 deficiency states are due to rare deletions, rearrangements, or point mutations within the apo A-I/C-III/A-IV gene complex. Reproduced with permission from Hirano, K., et al. Jul 21, 2005. series 1(9):[Full Text]. Rader DJ, deGoma EM. Fibroblasts and macrophages from Tangier patients are characterized by defective lipid, cholesterol, and phospholipid efflux. Recombinant apo A-1 Milano mimics the activity of nascent HDL and has shown promise in early trials in patients with acute coronary syndromes. 2007 Mar. Eslick GD, Howe PR, Smith C, et al.

A significant (albeit small) change in serum electrolytes—a reduction in potassium and increases in sodium and serum bicarbonate—was also found in the torcetrapib patients. 2002 May 7. Statins lower total cholesterol and represent the most efficacious way to lower the ratio of total cholesterol to HDL-C. Statins decrease clinical events in patients with low HDL-C.151 As noted earlier, pharmacologic therapies for raising HDL levels, notably niacin and inhibition of CETP, have not yet shown efficacy in cardiovascular outcome trials. Medscape Reference Feature Series - Lipid Newsletter. [43, 44, 45]. JAMA. Third JL, Montag J, Flynn M, et al. (2000). [The relationship between high-density lipoproteins, thromboxane B2 and arteriosclerosis in a case of primary hypoalphalipoproteinemia]. [Medline]. Randomized trial of estrogen plus progestin for secondary prevention of coronary heart disease in postmenopausal women. Patients suffer from symptoms caused by the accumulation of cholesteryl ester in many tissues throughout the body (Fig. [Medline]. Gemfibrozil and fenofibrate modestly raise the HDL cholesterol level. The tonsils are enlarged and show distinctive alternating bands of red, orange, or yellowish white striations overlying the normal red mucosa. 1989 Dec. 80(12):1345-9. Vega GL, Grundy SM. You will see meanings of Familial HDL Deficiency in many other languages such as Arabic, Danish, Dutch, … Effect of recombinant ApoA-I Milano on coronary atherosclerosis inpatients with acute coronary syndromes: a randomized controlled trial. Overall, fibrates reduce the risk for major coronary events by 25%, whereas currently available data for niacin suggest about a 27% reduction. A severe type of this deficiency … 1990 Aug. 86(2):379-84. 2008 Mar. Gebauer SK, Destaillats F, Dionisi F, Krauss RM, Baer DJ. 2012. Int J Cardiol. Mutations in ABCA1 have been shown to be the cause of Tangier disease (TD) and some forms of familial hypoalphalipoproteinemia (HA), two genetic disorders characterized by low plasma HDL levels. Cardiosource: American College of Cardiology. It is still controversial whether patients with homozygous Tangier disease develop premature CHD. ABCA1 is the cholesterol/phospholipid efflux protein that is defective in patients with Tangier disease and familial HDL deficiency. 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. With regard to HA, the ATP III report stated, "Low HDL cholesterol is a strong independent predictor of CHD [coronary heart disease]. Clinical manifestations in patients with Tangier disease. It is unclear whether pharmacologic agents should be used to raise the HDL cholesterol level in otherwise healthy persons, because no published clinical trials are available that demonstrate a benefit. Looking for familial high-density lipoprotein (HDL) deficiency? Saku K, Zhang B, Shirai K, et al. In a study by AIM-HIGH Investigators et al, the addition of niacin to statin therapy did not provide any clear benefit to patients with cardiovascular disease and low HDL levels. It may be proatherogenic if the VLDL-LDL cholesteryl ester is taken up by arterial macrophages. It is not known whether FHA is a discrete genetic disorder. [Full Text]. Additionally, the combination products that include simvastatin or lovastatin plus long-acting niacin (ie, Advicor, Simcor) were withdrawn from the U.S. market at the beginning of 2016 and are no longer available. Treatment There are drugs that can increase serum HDL such as niacin or gemfibrozil . (B) Altered actin cytoskeletons observed in fibroblasts and macrophages from TD patients. [Medline]. Instruct patients who smoke to stop smoking, tell persons who are overweight to manage their weight, and encourage individuals who are sedentary to engage in regular exercise. 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. [Medline]. An apo A-I mimetic peptide under development, D-4F, is targeted not at raising HDL but at changing pro-inflammatory HDL into anti-inflammatory HDL in high-risk patients. 35(3):640-6. However, its association with and promotion of atherosclerosis may require a variety of surgical interventions, as follows: Cardiac catheterization, coronary angiography, and various percutaneous interventions for coronary heart disease (CHD), Coronary bypass grafting surgery for patients with CHD, Percutaneous interventions and bypass procedures for peripheral vascular disease, Carotid endarterectomy for carotid disease, Gastric stapling and other related intestinal surgeries for weight reduction and the management of metabolic syndrome. Rader DJ. [Medline]. [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. Vasc Health Risk Manag. Satta MA, Scoppola A, Melina D, et al. High-density lipoproteins as an emerging therapeutic target for atherosclerosis. Dietary management should follow the NCEP guidelines for lowering frequently associated low-density lipoprotein (LDL) cholesterol, which is the primary target in lipid management [Medline]. 290(17):2292-300. The primary endpoint of ARBITER 2 was change in common carotid intima-media thickness (CIMT). Hulley S, Grady D, Bush T, et al. Furthermore, the FHA patients had a selective decrease in the HDL2 apoA-I (without apoA-II) particle.109. [Medline]. [Medline]. Increased self-reported risk of coronary artery disease in Caucasians with extremely low HDL cholesterol due to mutations in ABCA1, APOA1, and LCAT. Individuals possessing apo Milano were found to have very low levels of HDL and yet, as a group, had a very low prevalence of atherosclerotic disease because most of their HDL was apo A-I Milano. 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. New Insights From the Framingham Offspring Study. Kort EN, Ballinger DG, Ding W, et al. Whenever possible, eliminate medications associated with low HDL cholesterol levels. The non–HDL-C goal is the same as the patient's LDL-C goal plus 0.8 mmol/L (30 mg/dL).97, Amy S. Paller MD, Anthony J. Mancini MD, in Hurwitz Clinical Pediatric Dermatology (Fourth Edition), 2011. [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. Biochim Biophys Acta. New York, NY: McGraw-Hill; 2001. vol 2: 2817-33. Managing isolated low HDL cholesterol is also important. Dioguardi N, Vergani C. [Familial alpha lipoprotein deficiency. Polyunsaturated fats should constitute up to 10% of total energy intake, and monounsaturated fats, up to 20% of total energy intake. [Medline]. 2500032-overview [36]. In the ARterial Biology for the Investigation of the Treatment Effects of Reducing Cholesterol (ARBITER 2) study, a double-blind, placebo-controlled trial was performed on an extended-release niacin/statin therapy. According to the ATP III executive summary, "After the LDL goal has been reached, emphasis shifts to weight reduction and increased physical activity (when the metabolic syndrome is present)." 2003 Nov 5. Follow an appropriate management strategy. The ATP III reported, "When a low HDL cholesterol is associated with high triglycerides (200-499 mg/dL), secondary priority goes to achieving the non-HDL cholesterol goal." People with familial HDL deficiency may develop cardiovascular disease at a relatively young age, often before age 50. The increases in HDL levels were much higher than can be achieved with existing lipid drugs. Cholesteryl ester transfer protein: a novel target for raising HDL and inhibiting atherosclerosis. [Medline]. The Lipid Research Clinics Prevalence Study. Share cases and questions with Physicians on Medscape consult. [Full Text]. Ahumada Ayala M, Jimenez Villanueva C, Cardoso Saldana G, et al. The radioactivity decay curve of 125 I labelled HDL was used for assessment of kinetics. 2004 Jul 13. [Medline]. The genetic defect or defects are not known; however, it has been suggested that FCH, familial hyperapobetalipoproteinemia, familial dysbetalipoproteinemia, and familial hypoalphalipoproteinemia may be variants of a single disorder. Eur J Haematol. Vergani's disease]. Atherosclerosis.
