Klin Lab Diagn 2018 ;63(6):324-332

FGBNU "Research Institute of General Pathology and Pathophysiology", Academy of Sciences of the Russian Federation, 125315, Moscow.

The abuse of food of carnivores (meat) by phylogeneticallyI herbivorous Homo sapiens (a patient) initiates atherosclerosis. Addressing biogenetic law of E. Haeckel that ontogeny recapitulates phylogeny (a universal anamnesis), we suggest a diagnostic technique that allows evaluation of the meat diet abuse by a herbivorous Homo sapiens. Read More

Authors:
A David Marais

Pathology 2019 Feb 28;51(2):165-176. Epub 2018 Dec 28.

Chemical Pathology Division, Pathology Department, University of Cape Town Health Science Faculty and National Health Laboratory Service, Cape Town, South Africa. Electronic address:

Apolipoprotein E (apoE), a 34 kDa circulating glycoprotein of 299 amino acids, predominantly synthesised in the liver, associates with triglyceride-rich lipoproteins to mediate the clearance of their remnants after enzymatic lipolysis in the circulation. Its synthesis in macrophages initiates the formation of high density-like lipoproteins to effect reverse cholesterol transport to the liver. In the nervous system apoE forms similar lipoproteins which perform the function of distributing lipids amongst cells. Read More

Klin Lab Diagn 2018 ;63(1):4-15

The Federal state budget scientifc institution "The research institute of general pathology and pathophysiology" of the Russian academy of sciences, 125315, Moscow, Russia.

According to phylogenetic theory of general pathology, when living in ocean all were carnivorous (piscivorous) fatty acids transferring to cells in form of non-polar triglycerides nitially began apoB-48 chylomicrons, continued lipoproteins of very low and low density and fnalized its apoB-100 endocytosis. The fatty acids are transferred by chylomicrons + lipoproteins of very low density + lipoproteins of low density and non-polar triglycerides are hydrolyzed by hepatic glycerolhydrogenase and co-enzyme apoC-III; according WHO classifcation, hyperlipoproteinemia corresponds to type V. On land, in herbivorous who are not yet synthesized insulin, apoB-48 and chylomicrons left process of non-polar triglycerides transferring. Read More

The spectrum of type III hyperlipoproteinemia.

J Clin Lipidol 2018 Nov - Dec;12(6):1383-1389. Epub 2018 Sep 14.

Centre Hospitalier de l'Universite Laval, Quebec, Quebec, Canada.

Background: Type III hyperlipoproteinemia is a highly atherogenic dyslipoproteinemia characterized by hypercholesterolemia and hypertriglyceridemia due to markedly increased numbers of cholesterol-enriched chylomicron and very-low-density lipoprotein (VLDL) remnant lipoprotein particles. Type III can be distinguished from mixed hyperlipidemia based on a simple diagnostic algorithm, which involves total cholesterol, triglycerides, and apolipoprotein B (apoB). However, apoB is not measured routinely. Read More

Pharmacological treatment options for severe hypertriglyceridemia and familial chylomicronemia syndrome.

Expert Rev Clin Pharmacol 2018 Jun 11;11(6):589-598. Epub 2018 Jun 11.

c Department of Metabolic Medicine/Chemical Pathology , Guy's and St Thomas' Hospitals , London , UK.

Introduction: A spectrum of disorders, ranging from rare severe cases of homozygous null lipoprotein lipase deficiency (LPLD)-familial chylomicronemia syndrome (FCS) to heterozygous missense LPLD or polygenic causes, result in hypertriglyceridemia and pancreatitis. The effects of mutations are exacerbated by environmental factors such as diet, pregnancy, and insulin resistance. Areas covered: In this review, authors discuss chronic treatment of FCS by ultra-low fat diets allied with the use of fibrates, omega-3 fatty acids, niacin, statins, and insulin-sensitizing therapies depending on the extent of residual lipoprotein lipase (LPL) activity; novel therapies in development target triglyceride (TG)-rich lipoprotein particle clearance.

Roles of high apolipoprotein E blood levels and HDL in development of familial dysbetalipoproteinemia in ε2ε2 subjects.

Clin Biochem 2018 Feb 20;52:67-72. Epub 2017 Nov 20.

Department of Endocrinology, University of Groningen and University Medical Center Groningen, 9700 RB Groningen, The Netherlands.

Objective: Familial dysbetalipoproteinemia (FD) or Type III hyperlipoproteinemia is a mixed hyperlipidemia closely associated with the ε2ε2 genotype of the common APOE polymorphism although not all homozygotes progress to FD. Unlike the polymorphism, few studies explore effects of apolipoprotein E (apoE) blood levels on FD development. Likewise, despite the known apoE2 lipoprotein binding preference for high-density lipoprotein (HDL); little work exists exploring HDL in FD. Read More

Case of familial hyperlipoproteinemia type III hypertriglyceridemia induced acute pancreatitis: Role for outpatient apheresis maintenance therapy.

World J Gastroenterol 2017 Oct;23(40):7332-7336

Division of Gastroenterology and Liver Disease, Department of Internal Medicine, University Hospitals Cleveland Medical Center, Case Western Reserve University, Cleveland, OH 44106, United States.

Hypertriglyceridemic pancreatitis (HTGP) accounts for up to 10% of acute pancreatitis presentations in non-pregnant individuals and is the third most common cause of acute pancreatitis after alcohol and gallstones. There are a number of retrospective studies and case reports that have suggested a role for apheresis and insulin infusion in the acute inpatient setting. We report a case of HTGP in a male with hyperlipoproteinemia type III who was treated successfully with insulin and apheresis on the initial inpatient presentation followed by bi-monthly outpatient maintenance apheresis sessions for the prevention of recurrent HTGP.

Current insights into the German lipoprotein apheresis standard: PCSK9-inhibitors, lipoprotein apheresis or both?

Atheroscler Suppl 2017 Nov 1;30:44-49. Epub 2017 Jun 1.

Department of Medicine II for Nephrology, Hypertension and Vascular Risks, AGAPLESION Markus Hospital, Frankfurt, Germany.

According to current European guidelines, lipid lowering therapy for progressive cardiovascular disease including cardiovascular events has to be focused on a target level for LDL-C. In contrast for Lp(a) a threshold has to be defined with respect to the method of measurement. However, due to new lipid lowering drug developments like PCSK9-inhibitors (PCSK-9-I) a therapeutic algorithm for patients with severe hypercholesterolemia or isolated Lipoprotein(a)-hyperlipoproteinemia with progressive cardiovascular disease may be necessary to manage the use of PCSK9-I, lipoprotein apheresis (LA) or both.

ABCG5/G8 gene is associated with hypercholesterolemias without mutation in candidate genes and noncholesterol sterols.

J Clin Lipidol 2017 Nov - Dec;11(6):1432-1440.e4. Epub 2017 Oct 4.

Unidad Clínica y de Investigación en Lípidos y Arteriosclerosis, Hospital Universitario Miguel Servet, Instituto de Investigación Sanitaria Aragón (IIS Aragón), CIBERCV, Universidad de Zaragoza, Zaragoza, Spain.

Context: Approximately 20% to 40% of clinically defined familial hypercholesterolemia (FH) cases do not show a causative mutation in candidate genes (mutation-negative FH), and some of them may have a polygenic origin.

Objective: The aim of this work was to study the prevalence of ABCG5/G8 genetic variants in mutation-negative FH, as defects in these genes relate to intestinal hyperabsorption of cholesterol and thus ABCG5/G8 variants could explain in part the mechanism of hypercholesterolemia.

Design, Setting, And Patients: We sequenced the ABCG5/G8 genes in 214 mutation-negative FH and 97 controls. Read More

Anti-PCSK9 antibodies for the treatment of heterozygous familial hypercholesterolemia: patient selection and perspectives.

Vasc Health Risk Manag 2017 4;13:343-351. Epub 2017 Sep 4.

Department of Pharmacological and Biomolecular Sciences, Università degli Studi di Milano.

Heterozygous familial hypercholesterolemia (FH) is a genetic disorder characterized by high low-density lipoprotein cholesterol levels from birth, which exposes the arteries to high levels of atherogenic lipoproteins lifelong and results in a significantly increased risk of premature cardiovascular events. The diagnosis of FH, followed by an appropriate and early treatment is critical to reduce the cardiovascular burden in this population. Phase I-III clinical trials showed the benefit of proprotein convertase subtilisin kexin 9 inhibitors, both alirocumab and evolocumab, in these patients with an average low-density lipoprotein cholesterol reduction ranging from -40% to -60%.

Novel treatment options for the management of heterozygous familial hypercholesterolemia.

Expert Rev Clin Pharmacol 2017 Dec 14;10(12):1375-1381. Epub 2017 Sep 14.

a First Propedeutic Department of Internal Medicine, Medical School , Aristotle University of Thessaloniki, AHEPA Hospital , Thessaloniki , Greece.

Introduction: Even though statins represent the mainstay of treatment of heterozygous familial hypercholesterolemia (FH), their low-density lipoprotein cholesterol (LDL-C) lowering efficacy is finite and most patients with FH will not achieve LDL-C targets with statin monotherapy. Addition of ezetimibe with or without bile acid sequestrants will also not lead to treatment goals in many of these patients, particularly in those with established cardiovascular disease. In this selected subgroup of the FH population, proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors provide substantial reductions in LDL-C levels, reduce cardiovascular morbidity and appear to be safe.

Effect of LDL cholesterol, statins and presence of mutations on the prevalence of type 2 diabetes in heterozygous familial hypercholesterolemia.

Sci Rep 2017 07 17;7(1):5596. Epub 2017 Jul 17.

Lipid and Vascular Unit, Department of Endocrinology and Nutrition, Hospital del Mar, Universitat Autònoma de Barcelona, Barcelona, Spain.

Patients with heterozygous familial hypercholesterolemia (HeFH) have been reported to be less vulnerable to type 2 diabetes mellitus (T2DM), although the mechanism is unknown. The aims of the present study were to assess the effects of low density lipoprotein (LDL) cholesterol concentration and the presence of FH-causing mutations on T2DM prevalence in HeFH. Data were collected from the Dyslipidemia Registry of the Spanish Arteriosclerosis Society. Read More

Comparison of Lipoprotein Electrophoresis and Apolipoprotein E Genotyping in Investigating Dysbetalipoproteinemia.

J Coll Physicians Surg Pak 2017 Jun;27(6):378-379

Department of Clinical Pathology, Northampton General Hospital, Cliftonville, Northampton, UK.

Dysbetalipoproteinemia is often associated with apolipoprotein E2E2 homozygosity; however, lipoprotein electrophoresis may also be used to assist in the diagnosis. The aim of this study was to compare apolipoprotein E (apo E) genotyping and lipoprotein electrophoresis in investigating dysbetalipoproteinemia. Data were collected over a three-year period from a lipid clinic in a tertiary referral centre and reviewed for apo E genotyping and lipoprotein electrophoresis. Read More

Apolipoprotein E - A Multifunctional Protein with Implications in Various Pathologies as a Result of Its Structural Features.

Comput Struct Biotechnol J 2017 6;15:359-365. Epub 2017 Jun 6.

Institute of Cellular Biology and Pathology "Nicolae Simionescu" of the Romanian Academy, 8 B. P. Hasdeu Street, Sector 5, 050568 Bucharest, Romania.

Apolipoprotein E (apoE), a 34 kDa glycoprotein, mediates hepatic and extrahepatic uptake of plasma lipoproteins and cholesterol efflux from lipid-laden macrophages. In humans, three structural different apoE isoforms occur, with subsequent functional changes and pathological consequences. Here, we review data supporting the involvement of apoE structural domains and isoforms in normal and altered lipid metabolism, cardiovascular and neurodegenerative diseases, as well as stress-related pathological states.

Toward an international consensus-Integrating lipoprotein apheresis and new lipid-lowering drugs.

J Clin Lipidol 2017 Jul - Aug;11(4):858-871.e3. Epub 2017 Apr 25.

Division of Clinical Pharmacology, Department of Internal Medicine, University of Kansas Medical Center, Kansas City, KS, USA.

Background: Despite advances in pharmacotherapy of lipid disorders, many dyslipidemic patients do not attain sufficient lipid lowering to mitigate risk of atherosclerotic cardiovascular disease. Several classes of novel lipid-lowering agents are being evaluated to reduce atherosclerotic cardiovascular disease risk. Lipoprotein apheresis (LA) is effective in acutely lowering the plasma concentrations of atherogenic lipoproteins including low-density lipoprotein cholesterol and lipoprotein(a), and novel lipid-lowering drugs may dampen the lipid rebound effect of LA, with the possibility that LA frequency may be decreased, in some cases even be discontinued.

In silico analyses of deleterious missense SNPs of human apolipoprotein E3.

Sci Rep 2017 05 30;7(1):2509. Epub 2017 May 30.

Programa de Pós-Graduação em Ciências Genômicas e Biotecnologia, Universidade Católica de Brasília, Brasília-DF, Brazil.

ApoE3 is the major chylomicron apolipoprotein, binding in a specific liver peripheral cell receptor, allowing transport and normal catabolism of triglyceride-rich lipoprotein constituents. Point mutations in ApoE3 have been associated with Alzheimer's disease, type III hyperlipoproteinemia, atherosclerosis, telomere shortening and impaired cognitive function. Here, we evaluate the impact of missense SNPs in APOE retrieved from dbSNP through 16 computational prediction tools, and further evaluate the structural impact of convergent deleterious changes using 100 ns molecular dynamics simulations.

Medizinische Klinik V (Nephrologie, Hypertensiologie, Rheumatologie, Endokrinologie, Diabetologie), Medizinische Fakultät Mannheim der Universität Heidelberg, Mannheim, Deutschland.

Congenital disorders of lipid metabolism are caused by a wide range of variants of the genes for receptors, apolipoproteins, enzymes, transfer factors, and cellular cholesterol transporters. Clinically most relevant are autosomal dominant familial hypercholesterolemia (FH) and familial combined hyperlipoproteinemia (FCHL). FH has a prevalence of 1:250. Read More

Design and rationale of the ODYSSEY DM-DYSLIPIDEMIA trial: lipid-lowering efficacy and safety of alirocumab in individuals with type 2 diabetes and mixed dyslipidaemia at high cardiovascular risk.

Cardiovasc Diabetol 2017 05 25;16(1):70. Epub 2017 May 25.

Sanofi, Paris, France.

Background: Type 2 diabetes mellitus (T2DM) is often associated with mixed dyslipidaemia, where non-high-density lipoprotein cholesterol (non-HDL-C) levels may more closely align with cardiovascular risk than low-density lipoprotein cholesterol (LDL-C). We describe the design and rationale of the ODYSSEY DM-DYSLIPIDEMIA study that assesses the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, versus lipid-lowering usual care in individuals with T2DM and mixed dyslipidaemia at high cardiovascular risk with non-HDL-C inadequately controlled despite maximally tolerated statin therapy. For the first time, atherogenic cholesterol-lowering with a PCSK9 inhibitor will be assessed with non-HDL-C as the primary endpoint with usual care as the comparator. Read More

Unidad Clínica y de Investigación en Lípidos y Arteriosclerosis, Hospital Universitario Miguel Servet, Instituto de Investigación Sanitaria Aragón (IIS Aragón), Zaragoza, Spain.

Introduction And Objectives: The equations used in the general population to calculate cardiovascular risk are not useful in genetic hypercholesterolemia (GH). Carotid plaque detection has proved useful in cardiovascular prediction and risk reclassification but there have been no studies of its usefulness in GH. The aim of this study was to determine the association between the presence of carotid artery plaque and the occurrence of cardiovascular events in patients with GH. Read More

Efficacy and Safety of Lomitapide in Japanese Patients with Homozygous Familial Hypercholesterolemia.

J Atheroscler Thromb 2017 Apr 2;24(4):402-411. Epub 2017 Feb 2.

National Cerebral and Cardiovascular Research Center.

Aim: There is an unmet need in Japan for more optimal lipid-lowering therapy (LLT) for patients with homozygous familial hypercholesterolemia (HoFH) who respond inadequately to available drug therapies and/or apheresis, to achieve goals of low-density lipoprotein cholesterol (LDL-C) reduction by 50% or to <100 mg/dL.

Methods: In this study, Japanese patients with HoFH on stable LLT and diet were treated with lomitapide, initiated at 5 mg/day and escalated to maximum tolerated dose (up to 60 mg/day) over 14 weeks. The primary efficacy endpoint was mean percentage change from baseline to Week 26 in LDL-C. Read More

Research Institute of Nephrology, I.P. Pavlov First Saint Petersburg State Medical University, Ministry of Health of the Russian Federation, Saint Petersburg, Russia.

Lipoprotein glomerulopathy (LPG) is a rare disease characterized by specific histological, immunomorphological, and ultrastructural changes. The main pathomorphological signs of LPG are lipoprotein thrombi in the lumen of the capillary loops, proteinuria, and dyslipoproteinemia as an increased concentration of apolipoprotein E (phenotypes E2/E3, E2/E4). A patient aged 47 years had nephrotic syndrome with a daily protein loss of 12. Read More

[Hyperlipoproteinemia and dyslipidemia as rare diseases. Diagnostics and treatment].

Vnitr Lek Fall 2016;62(11):887-894

Hyperlipoproteinemia (HLP) and dyslipidemia (DLP) are of course mainly perceived as diseases of common incidence and are typically seen as the greatest risk factors (RF) in the context of the pandemic of cardiovascular diseases. This is certainly true and HLP or DLP overall affect tens of percents of adults. However we cannot overlook the fact that disorders (mostly congenital) of lipid metabolism exist which, though not formally defined as such, amply satisfy the conditions for classification as rare diseases.

Value of the Definition of Severe Familial Hypercholesterolemia for Stratification of Heterozygous Patients.

Am J Cardiol 2017 03 2;119(5):742-748. Epub 2016 Dec 2.

Unidad Clínica e Investigación en Lípidos y Arteriosclerosis, Hospital Universitario Miguel Servet, IIS Aragón, Universidad de Zaragoza, Zaragoza, Spain.

Familial hypercholesterolemia (FH) is characterized by high low-density lipoprotein (LDL) cholesterol with co-dominant transmission and high risk of cardiovascular disease (CVD), although with high variability among subjects. Currently, CVD stratification tools for heterozygous FH (HeFH) are not available. A definition of severe HeFH has been recently proposed by the International Atherosclerosis Society (IAS), but it has not been validated. Read More
