Objective: Familial dysbetalipoproteinemia (FD) or Type III hyperlipoproteinemia is closely associated with the ε2ε2 genotype of the common APOE polymorphism although not all ε2 homozygotes develop FD indicating that additional factors play a role including insulin resistance (IR). The current study was undertaken to explore relationships and influences among factors, especially IR, that might elucidate FD progression pathways.
Methods: Bayesian network (BN) modeling, a probabilistic graphical exploratory data analysis tool that portrays relationships and influences among variables as simple diagrams, was applied to 52 e2e2 subjects. Read More

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

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.

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%.

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.

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.

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.

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

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

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.

Fasting hypertriglyceridemia is positively associated with the morbidity of coronary heart disease (CHD), and postprandial (non-fasting) hypertriglyceridemia is also correlated with the risk status for CHD, which is related to the increase in chylomicron (CM) remnant lipoproteins produced from the intestine. CM remnant particles, as well as oxidized low density lipoprotein (LDL) or very low density lipoprotein (VLDL) remnants, are highly atherogenic and act by enhancing systemic inflammation, platelet activation, coagulation, thrombus formation, and macrophage foam cell formation. The cholesterol levels of remnant lipoproteins significantly correlate with small, dense LDL; impaired glucose tolerance (IGT) and CHD prevalence. Read More

Familial type III hyperlipoproteinemia (HLP) was first recognized as a distinct entity over 60 years ago. Since then, it has proven to be instructive in identifying the key role of apolipoprotein E (apoE) in removal of the remnants of very low density lipoproteins and chylomicrons produced by the action of lipoprotein lipase on these triglyceride-transporting lipoproteins. It has additionally shed light on the potent atherogenicity of the remnant lipoproteins. Read More

Considerable evidence suggests that "the lower the better" is a reasonable approach for reducing cardiovascular risk by lowering LDL cholesterol levels. Despite the reduction in cardiovascular events and mortality achieved by statin therapy, significant residual risk remains, especially in severe hereditary hypercholesterolemia, such as familial hypercholesterolemia. Some new strategies to achieve even lower LDL levels are now available, including the addition of cholesterol absorption inhibitor ezetimibe, and the recently available Proprotein convertase subtilisin/kexin type 9 monoclonal antibodies.

Methods: ODYSSEY ESCAPE is a randomized, double-blind, placebo-controlled, parallel-group, 18-week, phase 3 study being conducted in the United States and Germany. Read More

Activation of nuclear factor-κB (NF-κB) by increased production of reactive oxygen species (ROS) might induce transcription and expression of different antioxidant enzymes and also of nitric oxide synthase (NOS) isoforms. Thus, we aimed at studying the effect of NF-κB inhibition, caused by JSH-23 (4-methyl-N (1)-(3-phenyl-propyl)-benzene-1,2-diamine) injection, on ROS and NO generation in hereditary hypertriglyceridemic (HTG) rats. 12-week-old, male Wistar and HTG rats were treated with JSH-23 (bolus, 10 μmol, i.

Background: Lipoprotein lipase (LPL) deficiency is a serious lipid disorder of severe hypertriglyceridemia (SHTG) with chylomicronemia. A large number of variants in the LPL gene have been reported but their influence on LPL activity and SHTG has not been completely analyzed. Gaining insight into the deleterious effect of the mutations is clinically essential. Read More

Aims: Homozygous familial hypercholesterolaemia (HoFH) is a rare disorder usually caused by mutations in both alleles of the low-density lipoprotein receptor gene (LDLR). Premature death, often before the age of 20 years, was a common fate for patients with HoFH prior to the introduction of statins in 1990 and the use of lipoprotein apheresis. Consequently, HoFH has been widely considered a condition exclusive to a population comprising very young patients with extremely high LDL cholesterol (LDL-C) levels. Read More
