Acute Stevia Consumption does not Alter Endocrine Responses in Individuals with Normal Weight, Overweight, and Type 2 Diabetes Mellitus.

BACKGROUND: Stevia is a plant-based non-nutritive sweetener. Acute effects of stevia ingestion on glycemia and hormonal responses have not been fully investigated. OBJECTIVE: This objective of this study was to evaluate the acute effects of beverages containing stevia alone and in combination with glucose on glycemic, hormonal, and appetite responses. METHODS: This study evaluated three cohorts of n=23 individuals with either normal weight (NW), overweight (OW), or type 2 diabetes mellitus (T2DM) for which each individual completed four test conditions in a randomized sequence crossover study design. The four test conditions were beverages containing stevia (75.6 mg steviol equivalents), water, glucose (30 g), and stevia+glucose (30 g glucose+75.6 mg steviol equivalents). Blood samples were collected before and for 180 min after beverage consumption. Assessments included net area under the curve (niAUC) and incremental maximal concentration values for plasma glucose, insulin, glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1, glucagon, and PYY. Appetite was assessed with visual-analog scale questions and energy consumption during an ad libitum meal. RESULTS: Responses to the stevia beverage did not differ significantly from those for water alone, and stevia + glucose did not differ significantly from glucose alone for any of the three groups. CONCLUSION: Acute stevia consumption did not materially alter responses for glycemia or hormones involved in glucose and appetite regulation, appetite ratings, or energy intake at a subsequent meal.

Effects of fenofibrate on atherogenic dyslipidemia in hypertriglyceridemic subjects.

BACKGROUND: The metabolic syndrome (MS) is often accompanied by atherogenic dyslipidemia, which is characterized by elevated triglycerides (TG), reduced high-density lipoprotein cholesterol (HDL-C), and elevated numbers of small, dense low-density lipoprotein (LDL) particles. HYPOTHESIS: It was hypothesized that a threshold exists for the circulating TG level needed to produce changes in LDL subclass distribution. METHODS: Hypertriglyceridemic (TG > or =300 and <1000 mg/dl) subjects with the MS were randomly assigned to placebo (n=50) or 130 mg/day of micronized fenofibrate-coated microgranules (n=96) for 8 weeks. RESULTS: In the overall analysis, fenofibrate treatment resulted in significant (p < 0.05) changes versus placebo in TG (-36.6%), non-HDL-C (-7.5%), very low-density lipoprotein-C (-32.7%), LDL-C (15.0%), HDL-C (14.0%), remnant lipoprotein-C (-35.1%), apolipoprotein B (-6.0%), apolipoprotein A-I (5.3%), and apolipoprotein C-III--29.7%). Changes in LDL particle diameter in the fenofibrate group were significantly inversely associated with the TG level achieved on treatment (p = 0.019). When individually matched for percent change in TG, subjects with on-treatment TG < 200 mg/dl, in contrast to those with on-treatment values > or =200 mg/dl, had significantly different median responses (p < 0.05) in LDL size (0.79 vs. -0.06 nm) and cholesterol carried by small (-35 vs. 21 mg/dl) and large (31 vs. 11 mg/dl) particles. CONCLUSION: These data support the view that a threshold exists below which the TG level must be lowered to produce shifts in LDL particle size.

Reduced treatment success in lipid management among women with coronary heart disease or risk equivalents: results of a national survey.

BACKGROUND: This survey assessed and compared National Cholesterol Education Program (NCEP) Third Adult Treatment Panel lipid treatment goal achievement for men versus women undergoing treatment of dyslipidemia. METHODS: Patients receiving treatment for dyslipidemia from physicians (N = 376) in the United States who were high prescribers of lipid medications were enrolled in the NCEP Evaluation Project Utilizing Novel E-Technology (NEPTUNE) II. Data from a single office visit were collected and entered into the NEPTUNE software on a personal digital assistant and uploaded to a central database via the Internet. RESULTS: Of the 4885 patients evaluated, 2103 (43%) were women. NCEP Third Adult Treatment Panel low-density lipoprotein cholesterol (LDL-C) goal achievement was similar between women and men with 0 or 1 risk factor (89% and 88%, respectively) and 2 or more risk factors (75% and 76%, respectively). However, fewer women than men achieved goal in the coronary heart disease and risk equivalents (CHD + CHD RE) category (50% vs 60%, respectively; P < .001). Logistic regression analyses examining the association between sex and LDL-C treatment goal achievement, and evaluating potential confounding by other predictors of treatment success, indicated an age-adjusted odds ratio of 0.66 (95% confidence interval, 0.56-0.77; P < .001) and a multivariate odds ratio of 0.76 (95% confidence interval, 0.62-0.93; P = .009) for women compared with men in the CHD + CHD RE category. CONCLUSIONS: Female sex was associated with lower likelihood of LDL-C goal achievement among patients with CHD + CHD RE. This relationship remained significant after adjustment for other significant predictors of treatment success.

Ethnic differences in achievement of cholesterol treatment goals. Results from the National Cholesterol Education Program Evaluation Project Utilizing Novel E-Technology II.

BACKGROUND: African Americans (AA) have the highest coronary heart disease mortality rate of any ethnic group in the United States. Data from the National Cholesterol Education Program Evaluation ProjecT Utilizing Novel E-Technology (NEPTUNE) II survey were used to assess ethnic differences in low-density lipoprotein cholesterol (LDL-C) goal achievement. METHODS: NEPTUNE II surveyed patients with treated dyslipidemia to assess achievement of treatment goals established by the Adult Treatment Panel III of the National Cholesterol Education Program. United States physicians working in primary care or relevant subspecialties enrolled 10 to 20 consecutive patients (May to September 2003), and patient data were recorded in Personal Digital Assistants and uploaded to a central database via the internet. RESULTS: Among 4,885 patients receiving treatment for dyslipidemia, 79.7% were non-Hispanic white (NHW) and 8.4% were AA. Non-Hispanic white and AA patients had significantly different frequencies of treatment success, with 69.0% and 53.7%, respectively, having achieved their LDL-C goal (P<.001). African-American patients were more likely to be in the highest risk category, and less likely to be using lipid drug therapy, taking high-efficacy statins, and receiving care from a subspecialist, but the difference in goal achievement remained significant (P<.001) after adjustment for these and other predictors of treatment success. CONCLUSIONS: The frequency of treatment success in dyslipidemia management was significantly lower in AA than NHW patients. Additional research is needed to elucidate reasons for this disparity and to evaluate strategies for improving goal achievement among AA patients receiving therapy for dyslipidemia.

Non-high-density lipoprotein cholesterol: the forgotten therapeutic target.

The National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) has acknowledged mounting evidence of an independent association between hypertriglyceridemia and coronary artery disease risk by issuing guidelines that identify non-high-density lipoprotein (HDL) cholesterol as a secondary target for therapy in patients with elevated triglyceride levels. In 2003, a national survey of outpatient lipid management was conducted for patients undergoing treatment by physicians who were high prescribers of lipid-altering drugs. Results of the NCEP Evaluation Project Utilizing Novel E-Technology II (NEPTUNE II) survey indicated much higher frequencies of low-density lipoprotein (LDL) cholesterol goal achievement compared with frequencies observed in a similarly designed survey in 1997. However, non-HDL cholesterol treatment success in the NEPTUNE II survey was markedly lower than that for LDL cholesterol overall and across risk categories. More aggressive therapy is therefore needed to achieve non-HDL cholesterol goals than LDL cholesterol goals. After achievement of LDL cholesterol goals, non-HDL cholesterol can be managed more aggressively by lowering LDL cholesterol or by using strategies that target a reduction in very-low-density lipoprotein cholesterol. Because the prevalence of hypertriglyceridemia in the United States is high and increasing, enhanced efforts to improve non-HDL cholesterol goal achievement have the potential to produce a substantial effect on public health.

Results of the National Cholesterol Education (NCEP) Program Evaluation ProjecT Utilizing Novel E-Technology (NEPTUNE) II survey and implications for treatment under the recent NCEP Writing Group recommendations.

The most recent national survey of compliance with the National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) guidelines was completed before ATP III and showed significant underachievement of low-density lipoprotein (LDL) cholesterol goals. The NCEP Evaluation ProjecT Utilizing Novel E-Technology (NEPTUNE) II was a national survey conducted in 2003. Of the 4,885 patients, 67% achieved their LDL cholesterol treatment goal, including 89%, 76%, and 57%, respectively, in the 0 or 1 risk factor, > or = 2 risk factors or coronary heart disease (CHD), and CHD risk equivalent categories. The percentage with triglyceride concentrations > or = 200 mg/dl (2.25 mmol/L) in each risk category who achieved their LDL cholesterol and non-high-density lipoprotein cholesterol goals was 64%, 52%, and 27%, respectively. Patients with diabetes (55%) and other CHD risk equivalents (40%) were less likely to have achieved their LDL cholesterol targets than those with CHD (62%). Of the 1,447 patients with cardiovascular disease, 75% could be classified as very high risk according to the new July 2004 NCEP Writing Group recommendations, and 17.8% of those at very high risk had an LDL cholesterol level of <70 mg/dl (<1.81 mmol/L). In conclusion, these results suggest improved lipid management compared with previous surveys. The largest treatment gaps were found for features new to ATP III as of July 2004, including goal achievement for patients with CHD risk equivalents and for non-high-density lipoprotein cholesterol targets. Most of those (75%) with cardiovascular disease in NEPTUNE II would be considered very high risk and candidates for aggressive therapy to reach the new optional treatment goals.

A multicenter, open-label study to evaluate satisfaction and menopausal quality of life in women using transdermal estradiol/norethindrone acetate therapy for the management of menopausal signs and symptoms.

AIM: This multicenter, open-label, single-arm study evaluated subject satisfaction and improvements in menopausal quality of life among menopausal women using the CombiPatch transdermal system consisting of 17beta-estradiol 0.05 mg plus norethindrone acetate 0.14 mg in a matrix patch formulation. METHODS: The 193 postmenopausal women between the ages of 45 and 65 years who comprised the modified intent-to-treat population (at least one patch and one efficacy assessment) were required to have reported at least five daily moderate-to-severe hot flashes and episodes of nocturnal sweating upon study entry for at least 1 month and applied one patch twice a week for 12 weeks. At weeks 0, 6, and 12, the women completed the Menopause-Specific Quality of Life (MENQOL) Questionnaire and, as a secondary study outcome, reported the scale of their application site discomfort. During weeks 1-12, they also kept diary records of number and severity of hot flashes and four other menopausal symptoms. Skin tolerance and adherence of the transdermal system were evaluated at weeks 6 and 12 by qualified evaluators. At week 6 and the end of the study, both subjects and physicians rated their satisfaction with the system. RESULTS: Among women in the modified intent-to-treat population, transdermal 17beta-estradiol plus norethindrone acetate significantly reduced the mean daily number of moderate-to-severe hot flashes experienced by women from 4.1 at week 1 to 0.6 at week 12 (p < 0.0001). The mean ratings of headache severity, insomnia, and vaginal irritation/dryness also improved significantly by week 6 and were maintained at week 12. At week 12, 92.4% of the subjects and 97.3% of the physicians reported that they were 'satisfied' or 'very satisfied' with the transdermal hormone delivery system. CONCLUSIONS: The results of this study compare favorably with previous placebo-controlled studies of transdermal hormone therapy in managing menopausal signs and symptoms. Furthermore, quality of life was significantly improved by the transdermal hormone therapy system, and both subjects and physicians reported high levels of satisfaction.

Lipid responses to a dietary docosahexaenoic acid supplement in men and women with below average levels of high density lipoprotein cholesterol.

OBJECTIVE: To assess fasting lipid responses to a docosahexaenoic acid (DHA) supplement in men and women with below-average levels of high-density lipoprotein (HDL) cholesterol. METHODS: This randomized, double-blind, controlled clinical trial included 57 subjects, 21-80 years of age, with fasting HDL cholesterol concentrations < or =44 mg/dL (men) and < or =54 mg/dL (women), but > or =35 mg/dL. Subjects were randomly assigned to receive either 1.52 g/day DHA from capsules containing DHA-rich algal triglycerides or olive oil (control) for six weeks. RESULTS: There were no significant differences between groups in baseline lipid values. The DHA supplemented group showed significant changes [-43 (DHA) vs. -14 (controls) mg/dL, p = 0.015] and percent changes [-21% (DHA) vs. -7% (controls), p = 0.009] in triglycerides, total (12 vs. 3 mg/dL; p = 0.021 and 6% vs. 2%; p = 0.018) and low-density lipoprotein (17 vs. 3 mg/dL; p = 0.001 and 12% vs. 3%; p = 0.001) cholesterol concentrations, and in the triglyceride to HDL cholesterol ratio (-1.33 vs. -0.50, p = 0.010), compared with controls. In addition, there was a significant reduction in the percentage of LDL cholesterol carried by small, dense particles in the DHA supplemented group (changes = -10% vs. -3%, p = 0.025). CONCLUSIONS: Supplementation with 1.52 g/d of DHA in men and women with below-average HDL cholesterol concentrations raised the LDL cholesterol level, but had favorable effects on triglycerides, the triglyceride/HDL cholesterol ratio and the fraction of LDL cholesterol carried by small, dense particles. Further research is warranted to evaluate the net impact of these alterations on cardiovascular risk.

Dietary factors in the prevention of diabetes mellitus and coronary artery disease associated with the metabolic syndrome.

Coronary artery disease (CAD) and diabetes mellitus are 2 of the most common causes of morbidity and mortality in the United States. Diabetes has been recognized for decades as a major risk factor for the development of CAD. However, a growing consensus has emerged over the last several years that diabetes and CAD share a number of common precursors, which are metabolically linked and which often occur together in the same individual. This cluster of metabolic disturbances has been coined the metabolic syndrome by the Third Adult Treatment Panel (ATP III) of the National Cholesterol Education Program (NCEP). Other terms have been used to describe this constellation of risk factors, including syndrome X, the deadly quartet, and the insulin resistance syndrome.

Fibrates for treatment of the metabolic syndrome.

The National Cholesterol Education Program Adult Treatment Panel III has provided a clinical definition for the metabolic syndrome that is practical for use in an office setting. Identification and treatment of the metabolic syndrome is of enormous public health importance because it is associated with a marked elevation in coronary heart disease risk and affects nearly 25% of adults in the United States. First-line therapy is lifestyle modification, which includes body weight reduction, increased physical activity, and moderation of the dietary glycemic load. Drug treatments focusing on the major components of the syndrome (atherogenic dyslipidemia, hypertension, and a prothrombotic state) have demonstrated efficacy for reducing coronary heart disease events. Fibrates seem to be particularly effective in patients for whom a disturbance of the triglyceride-high-density lipoprotein axis is the primary lipid disorder. Fibrates also appear to influence a number of emerging risk factors, including hemostatic and inflammatory markers and indicators of improved vascular wall biology, which may contribute to their cardioprotective effects.

Inclusion of guar gum and alginate into a crispy bar improves postprandial glycemia in humans.

A novel induced viscosity fiber (IVF) crispy bar was formulated with the viscous dietary fibers alginate and guar gum. To evaluate the glycemic response and gastrointestinal tolerance to IVF crispy bars, nondiabetic healthy adult subjects (n = 48) were studied in a randomized, double-masked, crossover design. The control crispy bars and IVF crispy bars were identical except for the 2 dietary fibers contained in the experimental (IVF) bars. After an overnight fast, subjects consumed test bars containing 50 g carbohydrate. Their capillary blood glucose response was determined for 180 min postprandially. When subjects consumed IVF, the incremental blood glucose excursions were reduced (P < 0.05) at 15, 30, 45, and 120 min. At 180 min, the subjects' blood glucose concentration was maintained above the basal blood glucose concentration for both bars. Compared with controls, the incremental peak blood glucose concentration was reduced (P < 0.001) 30% when subjects consumed IVF. When subjects consumed IVF, the positive incremental area under the curve for glucose was reduced (P < 0.01) by 33% compared with controls. In the 24-h postprandial period after each treatment, the frequency and intensity of gastrointestinal tolerance symptoms did not differ. In conclusion, compared with a control crispy bar, the IVF crispy bar attenuated the postprandial glycemic excursion without gastrointestinal intolerance in healthy adult subjects.

Lipid responses in mildly hypertriglyceridemic men and women to consumption of docosahexaenoic acid-enriched eggs.

This randomized, double-blind, controlled clinical trial assessed lipid responses in mildly hyper-triglyceridemic men and women to consumption of docosahexaenoic acid (DHA)-enriched eggs or ordinary chicken eggs. The study included 153 subjects aged 21-80 years, with serum triglyceride concentrations between 140 and 450 mg/dL, inclusive, and serum total cholesterol concentrations < 300 mg/dL. Subjects were randomly assigned to receive either DHA-enriched (147 mg DHA/egg) or ordinary eggs (20 mg DHA/egg), added to their usual diets for six weeks (10 eggs/week). Both treatments significantly lowered triglycerides and increased high-density lipoprotein (HDL) cholesterol levels from baseline; however, these changes were not significantly different between treatments. Low-density lipoprotein (LDL) cholesterol concentrations increased significantly in subjects who consumed DHA-enriched eggs (p = 0.047 vs. control). This increase was significantly higher than that observed with ordinary eggs. However, there was no significant increase in cholesterol carried by small, dense LDL particles, as determined by nuclear magnetic resonance analysis. Results of exploratory analyses suggest favorable effects of the DHA-enriched eggs over ordinary eggs on triglyceride and HDL cholesterol levels in subjects with body mass index > or = 30 kg/m2; the DHA treatment produced a larger reduction in serum triglyceride concentration vs. ordinary eggs (-12.3 vs. 2.1%; p = 0.027), and there was a greater increase for HDL cholesterol in the DHA-enriched vs. ordinary egg group (5.0 vs. 1.1%; p = 0.040).

Food products containing free tall oil-based phytosterols and oat beta-glucan lower serum total and LDL cholesterol in hypercholesterolemic adults.

This randomized, double-blind, controlled trial evaluated the influence of low fat, low saturated fat food products that contained free tall oil-based phytosterols (TOP) and oat beta-glucan (from whole oats and bran concentrate) on serum lipid concentrations in adults with mild-to-moderate hypercholesterolemia. After a 5-wk National Cholesterol Education Program Step I diet lead-in period, 112 subjects incorporated one of two treatments into their diets for 6 wk: food products (cereal, snack bar and beverage) that provided 1.8 g TOP and 2.8 g beta-glucan/d and contained < or =3.0 g total fat and < or =1.0 g saturated fat (TOP/beta-glucan treatment) or similar control foods. The serum LDL cholesterol response from baseline to the end of study was significantly larger in the TOP/beta-glucan treated group than in the control group, in which there was no change (-3.7 vs. 0.4%; P = 0.013). Likewise, total cholesterol decreased in the TOP/beta-glucan treatment group and did not change significantly in the controls (-2.3 vs. 0.8%; P = 0.043). Serum HDL cholesterol and triglyceride responses did not differ between the groups. The results of this trial suggest that consumption of a group of low fat, TOP and beta-glucan- containing foods is a useful adjunct in the dietary management of hypercholesterolemia.

Pullulan is a slowly digested carbohydrate in humans.

Pullulan is an extracellular polysaccharide excreted by the fungus Aureobasidium pullulans. To evaluate the glycemic and breath hydrogen responses and gastrointestinal tolerance to pullulan, nondiabetic healthy adult subjects (n = 28) were studied in a randomized, double-masked, crossover design. After an overnight fast, subjects consumed beverages containing 50 g of carbohydrate from either maltodextrin (control) or pullulan. Capillary blood glucose response was determined for 180 min postprandially. Breath hydrogen response was determined for 8 h postprandially. Compared with control, incremental peak blood glucose concentration was reduced (P < 0.01) when subjects consumed pullulan (4.24 +/- 0.35 vs. 1.97 +/- 0.10 mmol/L). In addition, pullulan reduced (P < 0.01) the positive incremental area under the glucose curve by 50%. When subjects consumed pullulan, the incremental blood glucose excursions were reduced (P < 0.01) at 15, 30, 45, 60 and 90 min, but were maintained above basal glucose concentrations at 150 and 180 min. At 180 min, the blood glucose concentration was higher (P < 0.05) when subjects consumed pullulan compared with control, supporting the hypothesis that pullulan is digested slowly. Breath hydrogen concentrations were increased (P < 0.01) at 3, 4, 5, 6, 7 and 8 h postprandially when subjects consumed pullulan. In the first 24-h postprandial period, the frequency and intensity of flatulence was higher (P < 0.05) after subjects consumed pullulan compared with control. In conclusion, pullulan attenuated the postprandial glycemic excursion compared with an equivalent maltodextrin challenge. Pullulan also increased breath hydrogen excretion and the incidence of gastrointestinal intolerance symptoms, indicating that a portion of pullulan was malabsorbed.

Lipid management and the elderly.

Advancing age is an independent risk factor for the development of coronary heart disease. However, the significance of hypercholesterolemia as a cardiovascular risk factor in the elderly, has been widely debated. While no large-scale, randomized clinical trial has been conducted to evaluate cholesterol lowering solely in the elderly, evidence from older subgroups in several intervention trials supports the efficacy of lowering elevated low-density lipoprotein cholesterol for reducing cardiovascular risk in the elderly. Furthermore, although the relative risk of hyper-cholesterolemia for coronary heart disease incidence may be attenuated with advancing age, the population-wide impact of treating elevated cholesterol levels in the elderly would be large, due to the high frequency of coronary heart disease in the elderly. This article reviews key issues in the management of hyper-cholesterolemia with respect to coronary heart disease risk reduction in the elderly.

Consumption of diacylglycerol oil as part of a reduced-energy diet enhances loss of body weight and fat in comparison with consumption of a triacylglycerol control oil.

BACKGROUND: Diacylglycerol is a natural component of edible oils that has metabolic characteristics that are distinct from those of triacylglycerol. OBJECTIVE: We assessed the efficacy of an oil containing mainly 1,3-diacylglycerol in reducing body weight and fat mass when incorporated into a reduced-energy diet. DESIGN: The study was a randomized, double-blind, parallel intervention trial that was conducted at an outpatient clinical research center. The subjects (n = 131) were overweight or obese men (waist circumference > or = 90 cm) and women (waist circumference > or = 87 cm). Food products (muffins, crackers, soup, cookies, and granola bars) containing diacylglycerol or triacylglycerol oil and having the same fatty acid composition were incorporated into a reduced-energy diet (2100-3350-kJ/d deficit) for 24 wk. Percentages of change in body weight, fat mass, and intraabdominal fat area were assessed. RESULTS: In an intention-to-treat analysis, body weight and fat mass decreased significantly more in the diacylglycerol group than in the triacylglycerol group (P = 0.025 and 0.037, respectively). By the end of the trial, mean body weight had decreased 3.6% and 2.5% in the diacylglycerol and triacylglycerol groups, respectively. Fat mass decreased 8.3% and 5.6% in the diacylglycerol and triacylglycerol groups, respectively. CONCLUSION: Foods containing diacylglycerol oil promoted weight loss and body fat reduction and may be useful as an adjunct to diet therapy in the management of obesity.

Management of hypercholesterolaemia in postmenopausal women.

Increased rates of coronary heart disease (CHD) occur with advancing age in both sexes, although CHD rates in women lag behind those of men by about 10 years. There is a sharp increase in CHD rate among women after approximately 50 years of age. The reasons for this are not completely understood and are undoubtedly multifactorial. Cross-sectional data from large-scale population studies suggest that around the time of the menopause, low-density lipoprotein (LDL)-cholesterol levels increase by approximately 15 to 25%. Because this increase is larger than that observed in men over the same age span and closely approximates that observed in women after oophorectomy, it is likely that reduced circulating estrogen levels associated with menopause play a role in the adverse changes in both blood lipid levels and CHD incidence. There is clear evidence that treating hypercholesterolemia reduces cardiovascular risk in women, as well as in men. In the US National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) guidelines, diet and other lifestyle changes are recommended as first-line therapy. If the treatment goals cannot be achieved through non-pharmacological measures, drug therapy should be added. Of the available lipid-lowering agents, HMG CoA reductase inhibitors (statins) are the clear choice to decrease LDL-cholesterol levels. However the favourable effects of statins on high-density lipoprotein (HDL)-cholesterol and triglyceride levels are more modest, and statins are not known to decrease lipoprotein (a) [Lp(a)] levels. Estrogen or hormone replacement therapy (ERT/HRT) and nicotinic acid improve LDL- and HDL-cholesterol levels and also decrease Lp(a) levels. However, ERT/HRT is no longer recommended as first-line therapy for decreasing CHD risk. Nicotinic acid is particularly useful for decreasing triglyceride levels (as are fibrates) and raising HDL-cholesterol levels. Bile-acid sequestrants reduce LDL-cholesterol and slightly increase HDL-cholesterol levels. Both bile acid sequestrants and ERT/HRT tend to raise triglyceride levels, therefore they should be used cautiously in women with hypertriglyceridaemia. Treatment should be individualised for each patient. It is important to evaluate the primary form of dyslipidaemia, other CHD risk factors, comorbidities, and the extent of lipid improvement needed in order to reach treatment goals. The effects of each type of therapy and potential adverse effects should also be considered.
