The impact of an amino acid-based peritoneal dialysis fluid on plasma total homocysteine levels, lipid profile and body fat mass. (1/418)

BACKGROUND: The caloric load from glucose-based peritoneal dialysis (PD) fluids contributes to hypertriglyceridaemia, adiposity and, as result of anorexia, protein malnutrition in PD patients. It has been suggested that replacement of a glucose-based by an amino acids-based PD fluid (AA-PDF) for one exchange per day might improve the nutritional status and lipid profile. Due to the uptake of methionine from the dialysate, however, exposure to AA-PDF might aggravate hyperhomocysteinaemia, a frequently occurring risk factor for atherosclerosis in uraemic patients. METHODS: We studied the impact of a once daily exchange with 1.1% AA-PDF instead of glucose-based PD fluid for 2 months on plasma methionine and total homocysteine (tHcy) levels, lipid profile, butyrylcholinesterase (BChE) and body fat mass of seven stable PD patients. Results are expressed as mean+/-SEM. RESULTS: Methionine levels did not increase significantly during therapy, but tHcy levels increased substantially from 60+/-12 to 84+/-19 micromol/l after 1 month (P=0.039), and to 85+/-22 micromol/l after 2 months of AA-PDF treatment. Serum triglyceride concentration decreased from 3.0+/-0.4 mmol/l at entry to 2.6+/-0.5 mmol/l (at 1 month, P=0.041 vs baseline). Serum BChE also decreased from 6.9+/-0.4 U/ml at entry to 6.3+/-0.4 U/ml after 2 months (P=0.014). Total cholesterol concentration and cholesterol fractions did not change. The reduced exposure to glucose-based PD fluid for 2 months resulted in a 0.5 kg reduction in fat mass which was due mainly to a reduction in fat mass of the trunk region (0.3 kg, P=0.031). CONCLUSIONS: It is concluded that methionine-containing AA-PDF induces an increase in the plasma tHcy level. This might, potentially, offset the beneficial effects of an improved serum lipid profile and reduced fat mass on the risk of cardiovascular disease in PD patients. Lowering the methionine content of the fluid, therefore, may be required to overcome this adverse effect.  (+info)

Effects of alcohol and cholesterol feeding on lipoprotein metabolism and cholesterol absorption in rabbits. (2/418)

Alcohol fed to rabbits in a liquid formula at 30% of calories increased plasma cholesterol by 36% in the absence of dietary cholesterol and by 40% in the presence of a 0.5% cholesterol diet. The increase was caused almost entirely by VLDL, IDL, and LDL. Cholesterol feeding decreased the fractional catabolic rate for VLDL and LDL apoprotein by 80% and 57%, respectively, and increased the production rate of VLDL and LDL apoprotein by 75% and 15%, respectively. Alcohol feeding had no effect on VLDL apoprotein production but increased LDL production rate by 55%. The efficiency of intestinal cholesterol absorption was increased by alcohol. In the presence of dietary cholesterol, percent cholesterol absorption rose from 34.4+/-2.6% to 44.9+/-2.5% and in the absence of dietary cholesterol, from 84.3+/-1.4% to 88.9+/-1.0%. Increased cholesterol absorption and increased LDL production rate may be important mechanisms for exacerbation by alcohol of hypercholesterolemia in the cholesterol-fed rabbit model.  (+info)

Overexpression of human hepatic lipase and ApoE in transgenic rabbits attenuates response to dietary cholesterol and alters lipoprotein subclass distributions. (3/418)

The effect of the expression of human hepatic lipase (HL) or human apoE on plasma lipoproteins in transgenic rabbits in response to dietary cholesterol was compared with the response of nontransgenic control rabbits. Supplementation of a chow diet with 0.3% cholesterol and 3.0% soybean oil for 10 weeks resulted in markedly increased levels of plasma cholesterol and VLDL and IDL in control rabbits as expected. Expression of either HL or apoE reduced plasma cholesterol response by 75% and 60%, respectively. The HL transgenic rabbits had substantial reductions in medium and small VLDL and IDL fractions but not in larger VLDL. LDL levels were also reduced, with a shift from larger, more buoyant to smaller, denser particles. In contrast, apoE transgenic rabbits had a marked reduction in the levels of large VLDLs, with a selective accumulation of IDLs and large buoyant LDLs. Combined expression of apoE and HL led to dramatic reductions of total cholesterol (85% versus controls) and of total VLDL+IDL+LDL (87% versus controls). HDL subclasses were remodeled by the expression of either transgene and accompanied by a decrease in HDL cholesterol compared with controls. HL expression reduced all subclasses except for HDL2b and HDL2a, and expression of apoE reduced large HDL1 and HDL2b. Extreme HDL reductions (92% versus controls) were observed in the combined HL+apoE transgenic rabbits. These results demonstrate that human HL and apoE have complementary and synergistic functions in plasma cholesterol and lipoprotein metabolism.  (+info)

Binding of beta-VLDL to heparan sulfate proteoglycans requires lipoprotein lipase, whereas ApoE only modulates binding affinity. (4/418)

The binding of beta-VLDL to heparan sulfate proteoglycans (HSPG) has been reported to be stimulated by both apoE and lipoprotein lipase (LPL). In the present study we investigated the effect of the isoform and the amount of apoE per particle, as well as the role of LPL on the binding of beta-VLDL to HSPG. Therefore, we isolated beta-VLDL from transgenic mice, expressing either APOE*2(Arg158-->Cys) or APOE*3-Leiden (E2-VLDL and E3Leiden-VLDL, respectively), as well as from apoE-deficient mice containing no apoE at all (Enull-VLDL). In the absence of LPL, the binding affinity and maximal binding capacity of all beta-VLDL samples for HSPG-coated microtiter plates was very low. Addition of LPL to this cell-free system resulted in a 12- to 55-fold increase in the binding affinity and a 7- to 15-fold increase in the maximal binding capacity (Bmax). In the presence of LPL, the association constant (Ka) tended to increase in the order Enull-VLDL+info)

Lipid transfer inhibitor protein defines the participation of lipoproteins in lipid transfer reactions: CETP has no preference for cholesteryl esters in HDL versus LDL. (5/418)

Cholesteryl ester transfer protein (CETP) catalyzes the net transfer of cholesteryl ester (CE) between lipoproteins in exchange for triglyceride (heteroexchange). It is generally held that CETP primarily associates with HDL and preferentially transfers lipids from this lipoprotein fraction. This is illustrated in normal plasma where HDL is the primary donor of the CE transferred to VLDL by CETP. However, in plasma deficient in lipid transfer inhibitor protein (LTIP) activity, HDL and LDL are equivalent donors of CE to VLDL (Arterioscler Thromb Vasc Biol. 1997;17:1716-1724). Thus, we have hypothesized that the preferential transfer of CE from HDL in normal plasma is a consequence of LTIP activity and not caused by a preferential CETP-HDL interaction. We have tested this hypothesis in lipid mass transfer assays with partially purified CETP and LTIP, and isolated lipoproteins. With a physiological mixture of lipoproteins, the preference ratio (PR, ratio of CE mass transferred from a lipoprotein to VLDL versus its CE content) for HDL and LDL in the presence of CETP alone was approximately 1 (ie, no preference). Fourfold variations in the LDL/HDL ratio or in the levels of HDL in the assay did not result in significant preferential transfer from any lipoprotein. On addition of LTIP, the PR for HDL was increased up to 2-fold and that for LDL decreased in a concentration-dependent manner. Under all conditions where LDL and HDL levels were varied, LTIP consistently resulted in a PR >1 for CE transfer from HDL. Short-term experiments with radiolabeled lipoproteins and either partially purified or homogenous CETP confirmed these observations and further demonstrated that CETP has a strong predilection to mediate homoexchange (bidirectional transfer of the same lipid) rather than heteroexchange (CE for TG); LTIP had no effect on the selection of CE or TG by CETP or its mechanism of action. We conclude, in contrast to current opinion, that CETP has no preference for CE in HDL versus LDL, suggesting that the previously reported stable binding of CETP to HDL does not result in selective transfer from this lipoprotein. These data suggest that LTIP is responsible for the preferential transfer of CE from HDL that occurs in plasma. CETP and LTIP cooperatively determine the extent of CETP-mediated remodeling of individual lipoprotein fractions.  (+info)

Role of cholesterol ester mass in regulation of secretion of ApoB100 lipoprotein particles by hamster hepatocytes and effects of statins on that relationship. (6/418)

Our understanding of the factors that regulate the secretion of apoB100 lipoproteins remains incomplete with considerable debate as to the role, if any, for cholesterol ester in this process. This study examines this issue in primary cultures of hamster hepatocytes, a species in which both cholesterol and apoB100 metabolism are very similar to man. Addition of oleate to medium increased the mass of triglyceride and cholesterol ester within the hepatocyte and also increased the secretion of triglycerides, cholesterol ester, and apoB100 into the medium. Next, the responses of hamster hepatocytes to addition of either an HMG-CoA reductase inhibitor (lovastatin) or an acyl-CoA cholesterol acyltransferase inhibitor (58-035) to the medium, with or without added oleate, were determined. Effects of either agent were only evident in the oleate-supplemented medium in which cholesterol ester mass had been increased above basal. If oleate was not added to the medium, neither agent reduced apoB100 secretion; equally important, over the 24-hour incubation, neither agent, at the concentration used, produced any detectable change in intracellular cholesterol ester mass. However, in contrast to the estimates of mass, which were unchanged, under the same conditions radioisotopic estimates of cholesterol ester synthesis were markedly reduced. Any conclusion as to the relation of cholesterol ester mass to apoB100 secretion would therefore depend on which of the 2 methods was used. Overall, the data indicate a close correlation between the mass of cholesterol ester within the hepatocyte and apoB100 secretion from it and they go far to explain previous apparently contradictory data as to this relation. More importantly, though, taken with other available data, they indicate that the primary response of the liver to increased delivery of lipid is increased secretion rather than decreased uptake. These results point, therefore, to a hierarchy of hepatic responses to increased flux of fatty acids and increased synthesis of cholesterol that in turn suggests a more dynamic model of cholesterol homeostasis in the liver than has been appreciated in the past.  (+info)

Dietary pectin lowers sphingomyelin concentration in VLDL and raises hepatic sphingomyelinase activity in rats. (7/418)

There is evidence that cholesterol and sphingomyelin metabolism are interrelated, and thus the hypothesis tested was that dietary pectin, because it can alter hepatic cholesterol metabolism, would also alter hepatic sphingomyelin metabolism. For that purpose, 4-wk-old female Wistar rats were fed a diet without or with pectin (20 g/100 g) up to 21 d. In accordance with previous work, pectin consumption caused a significant (P < 0.001) reduction in hepatic (65%), whole plasma (37%), and VLDL (80%) cholesterol levels. Pectin also significantly reduced VLDL sphingomyelin concentrations (57%), but raised the amount of sphingomyelin in the high density lipoproteins (HDL)-2 fractions (58%), so that the level of sphingomyelin in whole plasma remained unaffected. Pectin did not affect the sphingomyelin concentration in the liver. Pectin consumption did not affect the hepatic sphingomyelin synthesizing enzymes, serine palmitoyltransferase, phosphatidylcholine:ceramide phosphocholine transferase, or phosphatidylethanolamine:ceramide phosphoethanolamine transferase. In contrast, dietary pectin activated both lysosomal (28%) and plasma membrane (26%) sphingomyelinase and thus may have enhanced sphingomyelin degradation. An attempt was made to describe the effects of dietary pectin on sphingomyelin metabolism in terms of altered fluxes through liver and plasma, with whole liver and whole plasma concentrations of sphingomyelin remaining unaffected.  (+info)

The lipoprotein profile of women with hyperprolactinaemic amenorrhoea. (8/418)

The aim of this study was to evaluate the lipoprotein profile in women with hyperprolactinaemic amenorrhoea and to establish whether effective dopamine agonist therapy might have a beneficial effect. Blood samples were collected from women with hyperprolactinaemic amenorrhoea and from controls matched for age, body mass index and smoking. Follow-up blood samples were collected from women on dopamine agonist therapy as treatment for their hyperprolactinaemia. Plasma cholesterol, high density lipoprotein cholesterol, low density lipoprotein (LDL) cholesterol, very low density lipoprotein cholesterol, triglycerides, serum oestradiol and prolactin were measured. No statistically significant differences were found in the lipoprotein profile of the patient (n = 15) and control (n = 15) groups. During treatment with the dopamine agonist, bromocriptine (n = 9), significant reduction in total cholesterol [4.87 (3.98-5.87) versus 5.60 (4.55-6.61) mmol/l, P = 0.024] and LDL cholesterol [3.22 (2.01-4.23) versus 3.72 (2.59-4.93) mmol/l, P = 0.033] was noted. We conclude that beneficial alterations in the lipoprotein profile may occur in response to effective dopamine agonist therapy, presumably as a consequence of return of ovarian function and alleviation of oestrogen deficiency. Women with hyperprolactinaemic amenorrhoea should be encouraged to take effective therapy to improve their lipoprotein profile and potentially reduce their cardiovascular risk.  (+info)

Most adults who are getting regular preventive healthcare are familiar with the lipid panel performed as a routine check for cholesterol levels. What they may not know is that the standard lipid panel can only identify about 40% of the people who are at high risk for heart disease. The result of this is that many adults mistakenly believe they have reduced their heart attack risk when they are actually carrying around ticking time bombs that could be defused with improved treatment. While the exact treatment for blood lipid problems varies, doctors seldom consider any such treatments without the test data to justify them. You could argue that the conventional cholesterol test actually increases the risk for heart attacks by leaving people unwisely complacent because of incomplete and inaccurate information about the nature of the fats in their blood. For instance, the LDL cholesterol number for bad cholesterol in the conventional tests is just a calculated estimate, not a direct measurement. ...

In humans, cholesterol is acquired from dietary sources and is produced de novo in the liver, intestine, and various other tissues. Normally, the balance among cholesterol synthesis, dietary intake, and degradation is adequate to maintain healthy cholesterol plasma levels; however, in subjects with hypercholesterolemia, elevation in low-density lipoprotein cholesterol leads to atherosclerotic deposition of cholesterol in the arterial walls (atherosclerosis) and subsequent coronary heart disease. Thus, it has been established that lowering the low-density lipoprotein cholesterol plasma concentrations effectively reduces cardiovascular morbidity and mortality. Additional lipid risk factors for coronary heart disease include elevated triglyceride, very low-density lipoprotein cholesterol and low-density lipoprotein cholesterol levels, and low levels of high-density lipoprotein cholesterol.. Despite changes in lifestyle and the availability of potent lipid-lowering agents, cardiovascular disease ...

Bolton-Smith et al. performed a cross-sectional analysis of the association between the intake of trans fatty acids and the presence of previously undiagnosed coronary heart disease among participants in the Scottish Heart Study. The intake of trans fatty acids was positively correlated with the ratio of LDL plus very-low-density lipoprotein cholesterol to HDL cholesterol. The odds ratios for coronary heart disease in the quintile with the highest intake as compared with the quintile with the lowest intake were elevated but not significantly so (1.26 in women and 1.08 in men). The results from this study were weak statistical associations that were not statistically significant - meaning the probability was unacceptably high the barely detectable associations could have occurred by chance. Even the study authors conclude,The results, therefore, do not support a major effect of dietary trans fatty acid…. ...

RESULTS In healthy subjects, log-transformed serum ferritin (LOGFER) correlated with basal serum glucose (r = 0.44, P = 0.007), but not with BMI, age, systolic or diastolic blood pressure, total cholesterol, VLDL cholesterol, HDL cholesterol, total triglycerides, VLDL triglycerides, serum insulin, or HbA1c (all P = NS). Identical results were obtained when the two lowest quartiles of serum ferritin were evaluated separately. However, in the two highest quartiles, LOGFER correlated with BMI (0.50, P = 0.02), diastolic blood pressure (r = 0.8, P , 0.0001), serum LDL cholesterol (r = 0.57, P = 0.01), VLDL cholesterol (r = 0.48, P = 0.03), total cholesterol and HDL2 and HDL3 subtractions of HDL cholesterol (r = −0.68, −0.76, −0.55, P = 0.001. , 0.0001, and 0.01, respectively), total triglycerides (r = 0.60, P = 0.006), HDL2/HDL3 quotient (P = −0.71, P = 0.001), VLDL triglycerides (r = 0.65, P = 0.004), and serum uric acid (r = 0.51, P = 0.03), but not with systolic blood pressure (r = 0.38, ...

Now that we have seen the issue of word choice when discussing HDL we can appreciate that LDL and LDL-cholesterol are NOT the same! With this in mind now we can discuss measuring the levels of LDL cholesterol within the blood. It is important to understand that there are both indirect and direct methods of calculating this value. In many labs, once the total cholesterol and HDL-cholesterol has been measured, for the sake of convenience and cost, the LDL cholesterol is mathematically calculated. The formula is listed below.. LDL-cholesterol = (Total cholesterol) - (HDL-choesterol) - (Triglycerides/5). Triglycerides/5 is a number used to estimate the amount of VLDL-cholesterol in the serum. And this element of the formula can be the downfall of the indirect method. That is to say, very high levels of triglycerides will compromise the accurate of this approximation and require the direct measurement of LDL-cholesterol.. WHEN READING AN LDL (**LDL-CHOLESTEROL!) VALUE MAKE SURE YOU ARE AWARE IF THIS ...

This randomized, double-blind, placebo-controlled clinical trial was conducted to investigate the effects of an extract of Angelica gigas Nakai (AGNE) on blood triglycerides (TG).. To do so, 100 Korean subjects (130 mg/dL ≤ fasting blood TG ≤ 200 mg/dL) were randomized to receive either 1 g/day of AGNE (as A. gigas Nakai extract 200 mg/d) or a placebo for 12 weeks.. Outcomes were efficacy TG, lipid profiles, atherogenic index, and safety parameters.. Results showed that TG, free fatty acids and very low-density lipoprotein cholesterol (VLDL-C) concentration and TG/HDL-C ratio in the AGNE group were significantly reduced compared to the placebo group (p , 0.05). There were no statistically significant differences between the groups for any other variables. No significant changes in any safety parameter were observed. In conclusion, ingestion of AGNE for 12 weeks is safe and may improve blood triglycerides and be useful to manage or prevent hypertriglyceridemia.. Jung SJ, Kim WR, Oh MR, Cha ...

Benecol is a margarine-like, vegetable-oil-based spread sold in eight-ounce tubs with the following labels: Proven to Reduce Cholesterol; No Trans Fat; No Trans Fatty Acids; and Each serving contains .85g of Plant Stanol Esters. Reid alleged that, despite Benecols premium price, he bought it in reliance on its representations that (1) plant stanol esters may reduce the risk for coronary heart disease; (2) Benecol is proven to reduce cholesterol; and (3) Benecol contains no trans fat or trans fatty acids. He alleged falsity and misbranding because: (1) Benecol does not contain sufficient plant stanol esters per serving; (2) Benecol does not contain the minimum amount of vitamin A required prior to any nutrient addition; and (3) Benecols label contains an inaccurate level of recommended consumption of plant stanol esters pursuant to federal law. Separately, he alleged that Proven to Reduce Cholesterol was false and misleading because no ...
Hypertriglyceridemia is an independent risk factor for cardiovascular disease. Dietary interventions based on protein restriction (PR) reduce circulating triglycerides (TGs), but underlying mechanisms and clinical relevance remain unclear. Here, we show that 1 week of a protein-free diet without enforced calorie restriction significantly lowered circulating TGs in both lean and diet-induced obese mice. Mechanistically, the TG-lowering effect of PR was due, in part, to changes in very low-density lipoprotein (VLDL) metabolism both in liver and peripheral tissues. In the periphery, PR stimulated VLDL-TG consumption by increasing VLDL-bound APOA5 expression and promoting VLDL-TG hydrolysis and clearance from circulation. The PR-mediated increase in Apoa5 expression was controlled by the transcription factor CREBH, which coordinately regulated hepatic expression of fatty acid oxidation-related genes, including Fgf21 and Ppara. The CREBH-APOA5 axis activation upon PR was intact in mice lacking the ...

Atherosclerotic cardiovascular diseases (ASCVDs) cause every fifth death worldwide. However, it is possible to prevent the progression of ASCVDs by reducing circulating concentrations of low-density lipoprotein cholesterol (LDL-C). Recent large meta-analyses demonstrated that by reducing the dietary intake of saturated fat and cholesterol, it is possible to reduce the risk of ASCVD events. Plant stanols, as fatty-acid esters, were developed as a dietary adjunct to reduce LDL-C levels as part of a heart-healthy diet. They reduce cholesterol absorption so that less cholesterol is transported to the liver, and the expression of LDL receptors is upregulated. Ultimately, LDL-C concentrations are reduced on average by 9–12% by consuming 2–3 g of plant stanol esters per day. In this review, we discuss recent information regarding the prevention of ASCVDs with a focus on dietary means. We also present new estimates on the effect of plant stanol ester consumption on LDL-C levels and the risk of ASCVD
plant stanol ester: antilipamic agent lowers serum total and low-density lipoprotein cholesterol concentrations of healthy children
As we can see cholesterol performs vital functions in our body. However, there are two types of cholesterol, the good and the bad.. High-density lipoprotein cholesterol (HDL), is also known as good cholesterol. This form takes the excess from our blood and transports it to the liver so it can be removed from our body. (4). Then you have, low-density lipoprotein cholesterol (LDL), otherwise called bad cholesterol. It also transports cholesterol around the body to where it might be needed. However, as well as depositing it to repair cells it leaves excess cholesterol behind in the arteries. Very low density lipoprotein cholesterol (VLDL) is another bad form of cholesterol. When levels of this substance are high it can contribute to cardiovascular disease. Triglycerides are another fatty substance in our blood, in fact its the most common type of lipid (fat) in the body. Their role is to store excess energy we produce from our diet. VLDL is responsible for carrying triglycerides around ...

ApoB-containing lipoproteins are assembled in at least 2 stages.11,13,17 The first of these, with the initiation step resulting in VLDL precursors, involves the folding of apoB into a precise secretion-competent conformation by interaction with the membrane lipids of the endoplasmic reticulum.17 In the present work, particles similar to the VLDL precursors were secreted in association with the HDL fraction of the medium (Figure 2), as has been shown previously.18,19 The second step, the maturation phase, depends on fusion of the VLDL precursor with a neutral, lipid-rich, apoB-free particle to produce full-size VLDL.17. Insulin inhibits the overall assembly of VLDL from apoB (see review1) by a mechanism that involves an increase in apoB degradation. Insulin injection directly into the portal vein in humans decreases VLDL output into the hepatic vein.4 A postprandial decrease in splanchnic VLDL output after an oral glucose load has also been reported,20 and increased portal insulin resulting from ...

TY - JOUR. T1 - Hepatitis C virus. T2 - A new class of virus associated with particles derived from very low-density lipoproteins. AU - Ye, Jin. PY - 2012/5/1. Y1 - 2012/5/1. N2 - Hepatitis C virus (HCV) infects 3% of the world population and is the leading cause of liver failure in the United States. A unique feature of HCV is that the viral particles are integral to very low-density lipoprotein (VLDL)-derived lipoprotein particles. The virus is assembled into VLDL in hepatocytes and released out of the cells together with VLDL. The virus then infects more hepatocytes by entering the cells through the low-density lipoprotein receptor, which mediates uptake of majorities of VLDL-derived lipoprotein particles. These observations suggest that HCV may belong to a novel class of viruses that is associated with VLDL. Understanding the relationship between HCV and VLDL metabolism may reveal new strategies to treat HCV infection.. AB - Hepatitis C virus (HCV) infects 3% of the world population and is ...
The lipids can be classified as TC, triglycerides, LDL, HDL and very low density lipoprotein (VLDL) cholesterol.. Total cholesterol: According to guidelines of National Cholesterol Education Program (NCEP), TC concentrations below 200 mg/dL have been regarded as desirable, whereas, concentrations greater than 240 mg/dL are referred to as hyperlipidemic. However, epidemiological evidence suggests that the risk of cardiac events decreases as TC levels fall approximately to 150mg/dL. Moreover, TC should be less than 180 mg/dL for children.. Triglyceride: The excess calories, alcohol or sugar in the body get converted into triglycerides and stored in fat cells throughout the body. The triglyceride concentration less than 150 mg/dL is regarded as normal, whereas, concentrations of 200-499 mg/dL are considered as high..
