Cicero, AFG, Landolfo, M, Ventura, F, Borghi, C
Expert opinion on pharmacotherapy. 2019;(10):1277-1288
Abstract
INTRODUCTION Atherosclerotic cardiovascular disease (ASCVD) and its clinical manifestations, remain a leading cause of death and disability worldwide. One of the major risk factors of ASCVD is dyslipidemia and all the available guidelines suggest the importance of strategies for lipid control in a remarkable proportion of the general population. AREAS COVERED This review focuses on the therapeutic options available for the management of lipid disorders in adults. EXPERT OPINION A large body of evidence supports that statins are still the first-line option for the management of hypercholesterolemia in a large percentage of patients. Statins should be given at the appropriate dose and considering the differences in lipid-lowering potency across the different medications. The main current challenge in the treatment of lipid disorders is the need of improving patient adherence and persistence to lipid-lowering treatments beyond the drug choice and the target lipid component. To achieve this goal, the best strategy would be to treat the patients by using the appropriate drugs given at adequate doses to reach the treatment target. We should also avoid drug interactions, monitor possible untoward side effects and promote adherence to treatment by tailoring treatment strategies to each patient.

Abstract
PURPOSE OF REVIEW Lipoprotein apheresis is a very efficient but time-consuming and expensive method of lowering levels of low-density lipoprotein cholesterol, lipoprotein(a)) and other apoB containing lipoproteins, including triglyceride-rich lipoproteins. First introduced almost 45 years ago, it has long been a therapy of "last resort" for dyslipidaemias that cannot otherwise be managed. In recent years new, very potent lipid-lowering drugs have been developed and the purpose of this review is to define the role of lipoprotein apheresis in the current setting. RECENT FINDINGS Lipoprotein apheresis still plays an important role in managing patients with homozygous FH and some patients with other forms of hypercholesterolaemia and cardiovascular disease. In particular, patients not achieving treatment goals despite modern lipid-lowering drugs, either because these are not tolerated or the response is insufficient. Recently, lipoprotein(a) has emerged as an important cardiovascular risk factor and lipoprotein apheresis has been used to decrease lipoprotein(a) concentrations in patients with marked elevations and cardiovascular disease. However, there is considerable heterogeneity concerning the recommendations by scientific bodies as to which patient groups should be treated with lipoprotein apheresis. Lipoprotein apheresis remains an important tool for the management of patients with severe drug-resistant dyslipidaemias, especially those with homozygous FH.

[New perspectives in the treatment of hypercholesterolaemia since the availability of PCSK9 inhibitors].
Pintó, X, Sarasa, I
Hipertension y riesgo vascular. 2019;(4):213-220
Abstract
The large clinical trials on cardiovascular prevention have demonstrated that the more atherogenic cholesterol is reduced the greater the preventive benefit, and neither a threshold value below which that effect disappears nor negative effects on health have been observed. Therefore, the objectives of hypercholesterolaemia control in patients at high cardiovascular risk are becoming ever stricter. The fact that most high-risk patients do not achieve these objectives requires, among other measures, rational use of available lipid-lowering drugs, including monoclonal antibodies that inhibit the protein PCSK9 (PCSK9i). The PCSK9i that are currently licensed for clinical use, evolocumab and alirocumab, have shown high potency in lowering LDL-cholesterol, which can exceed 60%, and other favourable effects on lipid profiles, including a very marked reduction of non-HDL cholesterol and apolipoproteinB. Likewise, through large-scale clinical trials, both drugs have demonstrated a preventive effect against cardiovascular diseases, and a high degree of safety. In addition, in the case of alirocumab, a reduction in all-cause mortality has been observed. However, the high cost of the PCSK9i means that prescription is restricted to patients at highest cardiovascular risk who cannot be controlled with high-potency statins and ezetimibe. It is to be hoped that the new guidelines that are to be issued soon by various scientific societies will define in greater detail the patients and the conditions in which we can use PCSK9i, drugs which currently constitute the greatest advance in hypercholesterolaemia of recent decades.

An evaluation of pitavastatin for the treatment of hypercholesterolemia.
Chan, P, Shao, L, Tomlinson, B, Zhang, Y, Liu, ZM
Expert opinion on pharmacotherapy. 2019;(1):103-113
Abstract
Statins are the first line of therapy to reduce low-density lipoprotein cholesterol (LDL-C) in order to decrease cardiovascular events. Pitavastatin is the latest statin to be introduced to the market. Areas covered: In this article, the authors review the efficacy, safety, and tolerability of pitavastatin. The authors also review a recent cardiovascular outcome study. Expert opinion: Pitavastatin produces dose-dependent reductions in LDL-C at lower doses than other statins. The maximum approved dose of 4 mg reduces LDL-C by about 40-49% in different patient groups and is equivalent to atorvastatin 20 mg in this effect. Pitavastatin undergoes minimal metabolism so drug-drug interactions are less likely than with many other statins, but it can interact with some drugs that inhibit drug transporters. Compared with other statins, it has been associated with greater increases in high-density lipoprotein cholesterol and it was found to be less likely to cause new onset diabetes. In a recent study in Japanese patients with stable coronary artery disease, pitavastatin 4 mg was more effective than pitavastatin 1 mg in reducing cardiovascular events. Therefore, the highest dose may be preferred in high-risk patients.

PCSK9 inhibitors: a non-statin cholesterol-lowering treatment option.
Pokrywka, GS
Postgraduate medicine. 2018;(3):287-298
Abstract
Elevated low-density lipoprotein cholesterol (LDL-C) plays a major role in the development of atherosclerotic cardiovascular disease. Statins are the first-line treatment to lower LDL-C in patients with hypercholesterolemia; however, some high cardiovascular risk patients may have inadequate responses to statin therapy or are intolerant to statins, and may need additional and/or alternative non-statin therapies to further reduce their LDL-C levels. Monoclonal antibodies that inhibit proprotein convertase subtilisin/kexin type 9 (PCSK9), a key regulator of circulating LDL-C levels, have received considerable attention as promising non-statin therapeutic options for the management of hypercholesterolemia. This review provides a brief overview of the history and science of PCSK9 inhibitors, focusing on two PCSK9 monoclonal antibodies that have been approved by the US Food and Drug Administration: alirocumab and evolocumab. Recently released and forthcoming clinical trial data will be discussed, as well as the practical application of patient populations that may benefit from PCSK9 inhibitors. Finally, the recent expert recommendations regarding the use of PCSK9 inhibitors and other non-statin therapies to treat patients with inadequate LDL-C-lowering on statin therapy will be summarized.

A Brief Drug Class Review: Considerations for Statin Use, Toxicity, and Drug Interactions.
Wooten, JM
Southern medical journal. 2018;(1):39-44
Abstract
For approximately 30 years, statins have been effectively used to control cholesterol, thereby reducing the morbidity and mortality associated with cardiovascular disease. Evidence-based recommendations regarding how these drugs are dosed and used have changed significantly through the years. There are seven statins approved for use in the United States, and although the mechanism of action pertaining to cholesterol reduction is the same for all statins, each has its own specific pharmacologic profile. One unique aspect of statin dosing is understanding the potential drug interactions associated with statin use; interactions can occur with all statins, but the mechanism and type of interaction can vary significantly among drugs. These interactions can result in significant elevations in statin blood concentrations, thereby increasing the risk of the adverse effects of statins, the most significant of which is muscle toxicity. Practitioners who care for patients receiving statins should understand the pharmacologic differences among these drugs, as well as the varied drug interaction potential that all statins possess.

New and Future Parenteral Therapies for the Management of Lipid Disorders.
Garcia, R, Burkle, J
Archives of medical research. 2018;(8):538-547
Abstract
Cardiovascular disease (CVD) is the leading cause of death in the world. According to the World Health Organization, an estimated 17.9 million people died from CVD in 2016, representing 31% of all global deaths. Of these deaths, 5% are due to myocardial infarction and stroke. Dyslipidemia is known as the major risk factor of atherosclerotic cardiovascular disease. With current therapies, about 60% of high-risk CVD patients do not achieve LDL-C goals, and in patients with familiar hypercholesterolemia (FH) at maximum intensity statin treatment, only 20% achieve LDL-C goals. We discuss new and future parenteral therapies for the management of lipid disorders.

Vaccines Targeting PCSK9: A Promising Alternative to Passive Immunization with Monoclonal Antibodies in the Management of Hyperlipidaemia?
Weisshaar, S, Zeitlinger, M
Drugs. 2018;(8):799-808
Abstract
Hypercholesterolaemia is frequently observed in patients with cardiovascular diseases (CVD) and is associated with increased mortality. Statin treatment has been the standard of care for reducing low-density lipoprotein cholesterol (LDL-C) to improve cardiovascular outcomes. However, statins have limited effects in some patients and may be discontinued due to adverse effects resulting in LDL-C above target levels. The proprotein convertase subtilisin kexin type 9 (PCSK9) is a pivotal regulator in the LDL-C metabolism by degrading the LDL-C receptor on hepatocytes. Inhibition of PCSK9 by monoclonal antibodies (mAb) significantly lowers LDL-C levels and is considered to reduce the likelihood of adverse cardiac events. However, such treatment regimens are not cost-effective, and require frequent administrations at high doses that may be associated with side effects and poor drug adherence. Furthermore, it has been shown that these PCSK9 medicines may trigger the formation of antidrug antibodies followed by a significant attenuation of the LDL-C-lowering effect. Active vaccination inducing high-affinity antibodies against PCSK9 with less frequent administration intervals may be a novel promising therapeutic approach to overcome the drawback of passive immunization with PCSK9 mAb. However there is a paucity of available clinical safety and efficacy data. This article discusses challenges in the development of PCSK9 vaccines and their potential therapeutic benefits by reviewing clinical studies that evaluated the safety and efficacy of PCSK9 mAb.
