In line with current guideline recommendations, patients at high cardiovascular risk are usually treated with statins for secondary as well as for primary prevention. While many studies investigated treatment goal achievement with regards to low-density lipoprotein (LDL-C) and total cholesterol (TC) there is paucity of data regarding high density lipoprotein (HDL-C), and/or triglycerides (TG).

These agents may eventually play a role as add-on therapy in those with dyslipidemias because of their significant effect on LDL-C. Further explorations in large phase 3 clinical trials are warranted to evaluate the effect of these therapies on cardiovascular clinical outcomes and long-term safety.

Although autoimmune syndromes such as systemic lupus erythematosus and dermatomyositis have been previously reported in association with statin use, vasculitis has not been well described. We present a patient with an antineutrophil cytoplasmic antibody-positive, predominantly cutaneous vasculitis, the temporal course of which was associated with simvastatin/ezetimibe use. The patient's serologic findings were consistent with drug-induced disease, with high titer antimyeloperoxidase, in addition to antinuclear and anti-Ro (SSA) antibodies. The patient demonstrated complete resolution of symptoms simply by withdrawing the drug.

The purpose of this paper is to examine the role of molecular mobility in the recrystallization process from the amorphous state of the anticholesterol drug ezetimibe. Both the molecular dynamics and crystallization kinetics have been studied using various experimental techniques, such as broadband dielectric spectroscopy (BDS), differential scanning calorimetry (DSC), and X-ray diffraction (XRD). Our investigations have shown that ezetimibe easily recrystallizes from the disordered state, both below and above its glass transition temperature (Tg = 336 K). Moreover, we found that an only slightly elevated pressure (5 MPa) significantly accelerates the recrystallization process at T > Tg. We predict that the structural relaxation time of amorphous ezetimibe at 293 K (storage temperature) and ambient pressure is only 22 days. This result corresponds to the characteristic time, determined from XRD measurements, for amorphous ezetimibe to recrystallize during storage at Troom = 298 K. It leads to the conclusion that the molecular mobility reflected in structural relaxation of ezetimibe is mainly responsible for devitrification of this drug. Finally, we determined a relatively easy way to improve the physical stability of the drug by preparing a binary amorphous ezetimibe-Soluplus mixture. Ezetimibe in an amorphous mixture with 20 wt % Soluplus has a much better (over six times) solubility than the pure crystalline material.

Reducing the level of low-density lipoprotein cholesterol (LDL-C) with statins induces important pleiotropic effects such as platelet inhibition. An insufficient LDL-C reduction often is treated with ezetimibe, an intestinal cholesterol absorption inhibitor, in combination with a low statin dose. It is not known whether this combination therapy has the same pleiotropic effects as a statin monotherapy.
The inhibition of cholesterol synthesis by a statin enhances intestinal absorption of both cholesterol and various phytosterols. The atherogenic role of phytosterols, well proven in hypersitosterolemia, is now suspected in patients with premature coronary artery disease. The cholestanol/cholesterol ratio can be used as a marker of intestinal cholesterol absorption. Individuals with elevated ratio ("high absorbers") have less favourable cholesterol-lowering response and cardiovascular protection with statin therapy as compared to individuals with low ratio ("high synthesizers"). They may benefit of an adjunct therapy with phytostanols or ezetimibe, both being capable to reduce plasma concentrations of cholesterol and of phytosterols.

The study recruited 4,132 individuals (3,745 of whom were ≥18 years of age); 2,752 of those enrolled were molecularly diagnosed FH cases. Mean follow-up was 5.1 ± 3.1 years; 71.8% of FH cases were on maximal LLT, and an LDL-C treatment target <100 mg/dl was reached by only 11.2% of patients. At follow-up, there was a significant increase in the use of ezetimibe, drug combinations with statins, and maximal LLT. The presence of type 2 diabetes mellitus, a defective allele mutation, ezetimibe use, and the absence of previous ASCVD were predictors of the attainment of LDL-C goals.
Recent studies revealed the importance of transporters in the behaviors of small molecules in the body. In mammals, the presence of a lot of transporters has been suggested, such as ATP-binding cassette (ABC) transporters and solute ligand carrier (SLC) transporters, some of which are clarified to be causative genes for various kinds of genetic disorders. In addition, a lot of transporters are known to mediate cellular import or export of drugs, to contribute to the pharmacokinetics of substrate drugs and to be involved in the interindividual differences of drug responses. In this review, I introduce our recent work on the transporter-mediated regulation of pharmacokinetics of lifestyle-related substances, such as cholesterol and urate.

Intestinal cholesterol absorption is specifically inhibited by the 2-azetidinone cholesterol absorption inhibitor ezetimibe. Photoreactive ezetimibe analogues specifically label a 145-kDa protein in the brush border membrane of enterocytes from rabbit small intestine identified as aminopeptidase N (CD13). In zebrafish and mouse small intestinal cytosol, a heterocomplex of M(r) 52 kDa between annexin II and caveolin 1 was suggested as a target of ezetimibe. In contrast, in the cytosol and brush border membrane vesicles (BBMV) from rabbit small intestine of control animals or rabbits treated with the nonabsorbable cholesterol absorption inhibitor AVE 5530, both annexin II and caveolin 1 were exclusively present as monomers without any heterocomplex formation. Upon immunoprecipitation with annexin II a 52-kDa band was observed after immunostaining with annexin II antibodies, whereas no staining of a 52-kDa band occurred with anti-caveolin 1 antibodies. Vice versa, a 52-kDa band obtained by immunoprecipitation with caveolin 1 antibodies did not stain with annexin II-antibodies. The intensity of the 52-kDa band was dependent on the amount of antibody and was also observed with anti-actin or anti-APN antibodies suggesting that the 52-kDa band is a biochemical artefact. After incubation of cytosol or BBMV with radioactively labelled ezetimibe analogues, no significant amounts of the ezetimibe analogues could be detected in the immunoprecipitate with caveolin-1 or annexin II antibodies. Photoaffinity labelling of rabbit small intestinal BBMV with ezetimibe analogues did not result in labelling of proteins being immunoreactive with annexin II, caveolin 1 or a 52-kDa heterocomplex. These findings indicate that the rabbit small intestine does not contain an annexin II/caveolin 1 heterocomplex as a target for ezetimibe.

The obesity epidemic has now spread worldwide. With increase in weight, there is an increase in dysregulated energy metabolism ultimately leading to dysfunction of multiple organ systems recognized as the metabolic syndrome. Nonalcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease worldwide, and is thought to be the hepatic manifestation of metabolic syndrome. It is a nondiscriminating disease affecting both children and adults and no socioeconomic class is spared. There is a well-defined increase in both liver-related and all-cause mortality. Current projections foresee a continued worsening in prevalence, especially with the increased rate of childhood obesity. Prevention would be the ultimate goal, but with continued trends in obesity, therapeutic options are needed to manage this chronic liver disease and prevent its complications of cirrhosis and even hepatocellular carcinoma. Therapies will need to be affordable, tolerable, and safe to be useful on such a large scale. This article will discuss some of the basic understanding of NAFLD, as well as review the currently tested therapies, some novel therapies, and potential future therapeutic options.

This was a Phase I, open-label, multiple-dose,3-period crossover study conducted in healthy adult men and women. Subjects received fenofibrate 145 mg alone, fenofibrate 145 mg with ezetimibe 10 mg, and ezetimibe 10 mg alone for 10 consecutive days, in an order determined by computerized randomization schedule. Blood samples were collected for up to 24 hours after dosing on study day 1 and up to 120 hours after dosing on study day 10 for determination of plasma concentrations of fenofibric acid, unconjugated (free) ezetimibe, and total (conjugated and unconjugated) ezetimibe using validated high-performance liquid chromatography methods with mass-spectrometric detection. Ezetimibe glucuronide concentrations were estimated by subtracting free ezetimibe concentrations from total ezetimibe concentrations.
Sitosterolemia is a rare autosomal recessive disorder characterised by a high plasma level of sterols. A homozygous mutation or the compound heterozygous mutation in the ABCG5 gene or the ABCG8 gene leads to a complete loss of function of the ATP-binding cassette (ABC) heterodimer transporter G5-G8, which is localised to the apical membrane of enterocytes and hepatocytes. In enterocytes, this complex rejects plant sterols, whereas it promotes their excretion into the bile in the liver. The loss of function of the transporter ABCG5-G8 leads to a high concentration of plasma plant sterols and to its accumulation in tissues. We report here a new mutation of sitosterolemia in a 59-year-old woman with xanthelasma, precocious atherosclerosis, haemolytic anemia and macrothrombocytopenia. She was treated before the availability of Ezetimibe wich is now the gold standard treatment of this disease.

Hypertension is the main clinic characteristic of ASH and asymmetric LV hypertrophy in patients with asymptomatic aortic stenosis independent of severity of aortic stenosis.
Adjustment of cardiac dimensions by measures of body size appears intuitively convincing and in patients with aortic stenosis, aortic valve area (AVA) is commonly adjusted by body surface area (BSA). However, there is little evidence to support such an approach.

The results show that lutein absorption is, at least in part, mediated by influx transporters NPC1L1 and SR-B1 rather than mediated by efflux transporters such as ABC (ATP-binding cassette) transporters.
Ezetimibe, 10 mg/day, was added to pravastatin 20 mg/day, while patients maintained the same antiretroviral regimen. Determinations of total, LDL-, and high density lipoprotein (HDL)-cholesterol, triglycerides, apoproteins, and inflammatory factors (homocystein and C-reactive protein) were performed at baseline, and at weeks 6, 12, and 24. Liver enzymes and creatinine phosphokinase were also assessed. Protease inhibitor (PI) or non-nucleoside reverse transcriptase inhibitor (NNRTI) Cmin was determined just before and 12 weeks after ezetimibe introduction.

Statins may exert important pleiotropic effects, ie, improve endothelial function, independently of their impact on LDL cholesterol. In humans, however, pleiotropic effects of statins have never been unequivocally demonstrated because prolonged statin treatment always results in reduced LDL cholesterol levels. We therefore tested the hypothesis that similar reductions in LDL cholesterol with simvastatin and ezetimibe, a novel cholesterol absorption inhibitor, result in different effects on endothelial function.

Homozygous familial hypercholesterolemia (HoFH) is a rare, genetic disorder characterized by an absence or impairment of low-density lipoprotein receptor (LDLR) function resulting in significantly elevated low-density lipoprotein cholesterol (LDL-C) levels. The cholesterol exposure burden beginning in utero greatly increases the risk for atherosclerotic cardiovascular disease (ASCVD) and premature death. The genetic heterogeneity of HoFH results in a wide range of LDL-C levels among both untreated and treated patients. Diagnosis of HoFH should, therefore, be based on a comprehensive evaluation of clinical criteria and not exclusively LDL-C levels. As treatment goals, the European Atherosclerosis Society and International FH Foundation suggest target LDL-C levels of <100 mg/dL (<2.5 mmol/L) in adults or <70 mg/dL (<1.8 mmol/L) in adults with clinical coronary artery disease or diabetes. The National Lipid Association (NLA) recommends that LDL-C levels be reduced to <100 mg/dL (<2.5 mmol/L) or by at least ≥50 % from pretreatment levels. Conventional therapy combinations that lower atherogenic lipoproteins levels in the blood, such as statins, ezetimibe, bile acid sequestrants and niacin, as well as lipoprotein apheresis, are usually unable to reduce LDL-C levels to recommended targets. Two recently approved agents that reduce lipoprotein synthesis and secretion by the liver are lomitapide, a microsomal triglyceride transfer protein inhibitor, and mipomersen, an apolipoprotein B antisense oligonucleotide. The newly approved inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9), evolocumab, also shows promise for the management of FH. Because of the extremely high risk for ASCVD, HoFH patients should be identified early.

High field magnetic resonance imaging (MRI) was performed to investigate the long-term effect of ezetimibe (eze), a cholesterol resorption blocker, on atherosclerotic lesion formation in the thoracic aorta of apolipoprotein E-deficient mice (apoE ( -/- )) in comparison to wild type mice (WT). Fifteen-month-old apoE ( -/- ) (Western type diet), apoE ( -/-eze ) (Western type diet with eze) which received eze (5 mc/kg/day) continuously, and age-matched WT (normal chow) were studied using contrast-enhanced 3D turbo-spin-echo sequences (RARE factor 2) on a 7 Tesla scanner. Vessel parameters were analyzed in the aortic root (AR) and aortic arch (AA) and compared to those found in histology. Plasma cholesterol levels were reduced at 15 months by 71% (P < 0.01) in apoE ( -/-eze ) compared to apoE ( -/- ). Vessel wall thickness was increased in the AR and AA in apoE ( -/- ) by 189.1 and 147.2%, respectively compared to WT. ApoE ( -/-eze ) showed reduced wall thickness in the AR (127.4%) and AA (102.8%, both P < 0.05 vs. apoE ( -/- )). A significant increase in total aortic vessel area was determined in the AR and AA in apoE ( -/- ) by 134.7 and 118.3%, respectively, compared to WT. This effect was inhibited in apoE ( -/-eze ) (AR: 126.7%, AA: 86.4%, both P < 0.05). Histological analysis confirmed the effect of eze observed by MRI and demonstrated a significant correlation between the two techniques (P < 0.001). MRI demonstrates that ezetimibe significantly reduces atherosclerotic disease in apoE ( -/- ). MRI is therefore a useful technique to perform in vivo interventional studies in experimental atherosclerosis.

Ergosterol-containing extracts from A. bisporus lowered hepatic triglyceride and modify the mRNA expression of cholesterol-related genes although the transcriptional regulation was unrelated to changes in plasma lipid profile. These extracts may be useful limiting hepatic steatosis and as bioactive ingredients to design novel functional foods preventing lifestyle-related diseases such as non-alcoholic fatty liver disease.
