Introduction: Familial hypercholesterolemia (FH) is characterized by extremely high levels of circulating low-density lipoprotein cholesterol (LDL-C) and is caused by mutations of genes involved in LDL-C metabolism, including LDL receptor (LDLR), apolipoprotein B (APOB), or proprotein convertase subtilisin/Kexin type 9 (PCSK9). Accordingly, PCSK9 inhibitors (PCSK9i) are effective in LDL-C reduction. However, no data are available on the pleiotropic effect of PCSK9i. To this end, we performed an untargeted metabolomics approach to gather a global view on changes in metabolic pathways in patients receiving treatment with PCSK9i. Methods: Twenty-five FH patients starting treatment with PCSK-9i were evaluated by an untargeted metabolomics approach at baseline (before PCSK9i treatment) and after 12 weeks of treatment. Results: All the 25 FH subjects enrolled were on maximal tolerated lipid-lowering therapy prior to study entry. After a 12 week treatment with PCSK9i, we observed an expected significant reduction in LDL-cholesterol levels (from 201.0 ± 69.5 mg/dL to 103.0 ± 58.0 mg/dL, p < 0.001). The LDL-C target was achieved in 36% of patients. After peak validation and correction, after 12 weeks of PCSK9i treatment as compared to baseline, we observed increments in creatine (p-value = 0.041), indole (p-value = 0.045), and indoleacrylic acid (p-value= 0.045) concentrations. Conversely, significant decreases in choline (p-value = 0.045) and phosphatidylcholine (p-value < 0.01) together with a reduction in platelet activating factor (p-value = 0.041) were observed. Conclusions: Taking advantage of untargeted metabolomics, we first provided evidence of concomitant reductions in inflammation and platelet activation metabolites in FH patients receiving a 12 week treatment with PCSK9i.

Autosomal Dominant Disorder

Familial hypercholesterolaemia is an autosomal-dominant disorder associated with mutations in the LDL receptor gene resulting in markedly elevated plasma low-density lipoprotein cholesterol levels. FH is significantly underrecognised with as many as 1 in 300 having the heterozygous form and 1 in 1 million having the homozygous form of the disease. Early diagnosis and treatment of FH is paramount to reduce the risk of premature atherosclerotic cardiovascular disease and death. The goal of treatment is to reduce LDL-C by 50 % from baseline levels with lifestyle modification, pharmacologic lipid-lowering therapy, LDL apheresis and in rare cases, liver transplantation. Pharmacologic treatment ranges from statin medications to newer agents such as lomitapide, mipomersin and PCSK9 inhibitors. Combination therapy is frequently required to achieve goal lipoprotein level reductions and prevent complications.

Pharmacological Management

Background and aims Untreated Familial Hypercholesterolemia (FH) leads to premature morbidity and mortality. In France, its epidemiology and management are understudied in ambulatory care. We described the clinical profile, pharmacological management, and clinical outcomes in a French sample of FH patients. Methods This was a retrospective longitudinal study on patients from The Health Improvement Network (THIN®) database in France, between October 2016-June 2019. Patients ≥18 years, with probable/definite FH based on the Dutch Lipid Clinic Network (DLCN) criteria were included. Baseline characteristics, lipid profile, lipid-lowering therapy (LLT), low-density lipoprotein-cholesterol (LDL-C) goal achievement; and disease management at 6-month of follow-up were analyzed. Results 116 patients with probable (n = 70)/definite (n = 46) FH were included (mean age:57.8±14.0 years; 56.0% women; 9.5% with personal history of cardiovascular events); 90 patients had data available at follow-up. At baseline, 77.6% of patients had LDL-C>190 mg/dL, 27.6% were not receiving LLTs, 37.9% received statins alone, 20.7% statins with other LLTs, and 7.7% other LLTs. High-intensity statins were prescribed to 11.2% of patients, 30.2% received moderate-intensity statins, and 8.6% low-intensity statins. Only 6.0% of patients achieved LDL-C goal. At 6-month of follow-up, statins discontinuation and switching were 22.7% and 2.3%, respectively. None of the patients received proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors at baseline nor follow-up. Conclusions Despite the existence of effective LLTs, FH patients are suboptimally-treated, do not achieve LDL-C goal, and exhibit worsened pharmacological management over time. Future studies with longer follow-up periods and assessment of factors affecting LDL-C management, including lifestyle and diet, are needed.

And Function

Background:One of the important factors in Low-Density Lipoprotein (LDL) metabolism is the LDL receptor (LDLR) by its capacity to bind and subsequently clear cholesterol derived from LDL (LDL-C) in the circulation. Proprotein Convertase Subtilisin-like Kexin type 9 (PCSK9) is a newly discovered serine protease that destroys LDLR in the liver and thereby controls the levels of LDL in plasma. Inhibition of PCSK9-mediated degradation of LDLR has, therefore, become a novel target for lipid-lowering therapy.Methods:We review the current understanding of the structure and function of PCSK9 as well as its implications for the treatment of hyperlipidemia and atherosclerosis.Results:New treatments such as monoclonal antibodies against PCSK9 may be useful agents to lower plasma levels of LDL and hence prevent atherosclerosis.Conclusion:PCSK9's mechanism of action is not yet fully clarified. However, treatments that target PCSK9 have shown striking early efficacy and promise to improve the lives of countless patients with hyperlipidemia and atherosclerosis.

Lipid Lowering Therapy

Familial hypercholesterolemia (FHC) is a common monogenic disease that occurs with a frequency of ~1:250 and is characterised by a high content of low-density lipoprotein (LDL) in the blood. This disease leads to the early development of atherosclerotic cardiovascular diseases (ACVD). Although the screening and diagnostics issues concerned with FHC are well developed and the modern lipid-lowering therapy can significantly improve the prognosis, the detectability of this disease remains extremely low. In recent years, the concept of FHC has undergone significant changes under the influence of large epidemiological studies, including verification of the FHC diagnosis using genetic tests. The article is aimed at discussing the clinical manifestations of FHC, as well as modern medical and extracorporal approaches to its treatment.Conclusion.Until the advent of modern lipid-lowering drugs, FHC had remained to be a disease with a poor prognosis due to early ACVD and the associated premature death. Today, the diseases is amenable to successful treatment, which, though not eliminating the genetic defect, allows almost the same life duration as in the general population to be achieved. However, all the possibilities of modern approaches to the treatment of this serious disease can be realized provided that a state-level screening program for such patients has been implemented.Conflict of interest: the authors declare no conflict of interest.

Abstract Aims To estimate the proportion of patients with a recent myocardial infarction (MI) who would be eligible for additional lipid-lowering therapy according to the 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines for the management of dyslipidaemias, and to simulate the effects of expanded lipid-lowering therapy on attainment of the low-density lipoprotein cholesterol (LDL-C) target as recommended by the guidelines. Methods and results Using the nationwide SWEDEHEART register, we included 25 466 patients who had attended a follow-up visit 6–10 weeks after an MI event, 2013–17. While most patients (86.6%) were receiving high-intensity statins, 82.9% of the patients would be eligible for expanded lipid-lowering therapy, as they had not attained the target of an LDL-C level of &lt;1.4 mmol and a ≥50% LDL-C level reduction. When maximized use of high-intensity statins followed by add-on therapy with ezetimibe was simulated using a Monte Carlo model, the LDL-C target was reached in 19.9% using high-intensity statin monotherapy and in another 28.5% with high-intensity statins and ezetimibe, while 50.7% would still be eligible for proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors. When use of alirocumab or evolocumab was simulated in those who were eligible for PCSK9 inhibitors, around 90% of all patients attained the LDL-C target. Conclusion  Our study suggests that, even with maximized use of high-intensity statins and ezetimibe, around half of patients with MI would be eligible for treatment with PCSK9 inhibitors according to the 2019 ESC/EAS guidelines. Considering the current cost of PCSK9 inhibitors, the financial implications of the new guidelines may be substantial.

Representatives of different groups of lipid-lowering drugs may have some differences in the nature and severity of the effect on the blood lipid spectrum. A new class of drugs, PCSK9 inhibitors, whose activity is associated with a protein involved in the control of low density lipoprotein receptors, has recently appeared. In clinical practice, this group is represented by monoclonal antibody preparations evolocumab and alirocumab. PCSK9 inhibitors are promising drugs for use in combination lipid-lowering therapy, which so far, given the results of clinical studies, can be recommended in the third place after statins and ezetimibe. In clinical studies, it was shown that alirocoumab and evolocumab alone or in combination with statins and/or other lipid-lowering drugs significantly reduce cholesterol levels in low density lipoproteins – by an average of 60%, depending on the dose.

BackgroundProprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are a major development in the prevention of cardiovascular disease (CVD) and is one of the most significant discoveries since the development of statin therapy. Administration of two human monoclonal antibodies to PCSK9 (alirocumab and evolocumab) can significantly reduce low-density lipoprotein cholesterol (LDL-c) concentrations, thus improving lipid management. Accordingly, guidelines on the specific indications for alirocumab and evolocumab usage have been released. This multicentre study aimed to estimate the proportion of patients treated for an acute myocardial infarction (MI) who could be considered for PCSK9 inhibitors under the current National Institute for Health and Care Excellence (NICE) lipid targets criteria.MethodsThe records of 596 patients in two large hospitals in Liverpool, UK were analysed. Information was collected on lipid profiles during and after admission, lipid-lowering therapy and previous CVD.ResultsAt least 2.2% of patients were eligible for PCSK9 inhibitors post-MI under the current NICE guidance. Additionally, 29% of patients failed to achieve LDL-c concentrations <2.0 mmol/L despite maximum statin therapy and failed to meet eligibility for PCSK9 inhibitors as per the NICE criteria. This cohort represents a group of patients ‘in limbo’, in which statin therapy alone is not sufficient to reduce LDL-c.ConclusionsPCSK9 inhibitors are expensive and so their use must be highly selective. At present, in a real-world setting with ezetimibe underprescribing, ~2% of patients are eligible and a further 30% are deprived of benefit and improved outcomes by lack of optimisation and/or potential use of PCSK9 inhibitors.

Aim: to evaluate the efficacy and safety of the use of evolocumab in patients with familial hypercholesterolemia (FH).Materials and methods: Fifteen patients with a definite FH were treated with PCSK9 inhibitors, in 11 patients with a history of CAD. Eight patients (53.3%) received evolocumab (Repata) subcutaneously 140 mg once every 2 weeks, their average age was 51.4±2.3 years, 6 men. Lipid spectrum, ALT, AST, creatinine, glucose, Lp (a) were evaluated after 3, 6, 12 and 18 months, the ECG and the clinical picture were monitored. Evolocumab was prescribed in connection with the failure to achieve the target LDL. Before the start of therapy, 7 patients received statins, 5 statins with ezetemib, 1 patient did not receive lipid-lowering therapy due to intolerance. The target LDL levels were considered: for very high risk patients less than 1.4 mmol/L, high risk – less than 1.8 mmol/L. Statistical processing of the material was performed using STATISTICA10.0.Results: On the background of evolocumab therapy, the average level of LDL after 3 months of therapy decreased by 56.4% (from 3.9±0.3 to 1.71±0.2 mmol/L), the effect persisted after a year. All patients did not stop the therapy; there were no side effects, including local ones. Target LDL was achieved in 62.5% of patients, the average LDL level after 3 months of therapy decreased by 56.4% in patients from the initial, including the case of monotherapy with evolocumab. The Lp (a) level during therapy decreased by 30%.Conclusions: Evolocumab allows to increase the achievement of the target LDL level on 40% in FH patients; target LDL level was achieved in 62.5%. LDL decreased after 3 months by 56.4%, remaining stable with prolonged therapy. The decrease in Lp(a) reached 30%. Evolocumab therapy was characterized by high adherence and the absence of side effects.
