The effects of bezafibrate and fenofibrate on serum lipoproteins and serum urinary uric acid were compared. In a double-blind, placebo-controlled, cross-over study, each drug was administered in random order for 6 weeks followed by a 3-week drug-free phase to ten men with primary hypertriglyceridemia. Serum triglyceride and cholesterol concentrations decreased significantly with both fenofibrate and bezafibrate, although no significant change in serum apolipoprotein B, serum low density lipoprotein (LDL) cholesterol or serum high density lipoprotein (HDL) cholesterol concentrations was apparent. Serum uric acid levels, which were elevated on placebo and bezafibrate, were significantly reduced by 20% by fenofibrate. This was associated with an increase in renal uric acid clearance of 30% during fenofibrate therapy. Because it seems likely that hypertriglyceridemia and hyperuricemia are linked by a common carbohydrate inducibility, we studied the acute hyperuricemic response to orally administered fructose. Fructose (50 g) caused the anticipated rise in serum urate reaching a peak between 60 and 90 minutes, which was quantitatively greater in the men with hypertriglyceridemia than in healthy controls. The serum uric response to fructose was unaffected by bezafibrate, but was converted to normal by fenofibrate. The hyperuricemic action of fenofibrate is of sufficient magnitude to be of therapeutic value in the management of patients whose hypertriglyceridemia is associated with gout.

A large segment of the population gradually develops insulin resistance, and the related metabolic syndrome is one of the most frequent causes of atherosclerosis. Searching for a practical indicator of insulin resistance, we studied the correlations between fasting serum insulin level, the general manifestations of insulin resistance syndrome, and various aspects of coronary artery disease in 797 men and 322 women. After we classified patients according to the quartiles of serum insulin level, we noted in the top quartile the presence of practically all manifestations of insulin resistance syndrome in persons of both sexes (e.g., increased waist/hip ratio, body mass index, glucose, uric acid, triglycerides, apolipoprotein B and decreased high-density lipoprotein cholesterol levels as well as apolipoprotein A-I/B ratios, and so forth). We also noted a higher prevalence of hypertension, diabetes mellitus, and type IV hyperlipidemia. Significantly more women in the fourth than in the first quartile had angiographically documented significant stenosis of the coronary arteries (p = 0.0016, odds ratio 2.9, 95% confidence interval 1.5 to 5.6) and previous myocardial infarction (p = 0.0297, odds ratio 2.1, 95% confidence interval 1.1 to 4.1). Men in both the first and the fourth quartile had a more disturbed lipid profile and a higher prevalence of significant stenoses of coronary arteries and/or previous myocardial infarction than women; there was a tendency toward a lower prevalence of alcohol consumption (p = 0.0503), a higher prevalence of gout (p = 0.0634), and previous myocardial infarction (p = 0.0791) in men in the fourth than in the first quartile.(ABSTRACT TRUNCATED AT 250 WORDS)

The association between serum uric acid concentration and some cardiovascular risk factors was examined in a working Hong Kong Chinese population (mean age 38 years), consisting of 910 men and 603 women. There was no significant age-related rise in serum uric acid concentration. Positive associations were found between serum uric acid concentration and body mass index, waist hip ratio, systolic and diastolic blood pressure, urea, creatinine, protein, glucose (fasting and 2 hours after 75 g oral glucose load), 2 hour insulin, triglycerides, and apolipoprotein B in men. Similar, but fewer, associations were seen in women, with the addition of a positive association with age. In both sexes, serum uric acid was negatively associated with high-density lipoprotein cholesterol. These findings complement the well-known clinical association between gout and cardiovascular and metabolic diseases, such as hypertension, hyperlipidaemia and diabetes mellitus, and suggest that serum uric acid may be a marker for the presence of an adverse cardiovascular risk factor profile.

Using logistic regression analysis, we investigated whether or not excessive alcohol intake and increased BMI, both of which are known causes of lipid metabolism abnormality, are associated with increased serum triglyceride, apolipoprotein B concentrations and decreased high-density lipoprotein cholesterol (HDL-C), high-density lipoprotein 2 cholesterol (HDL2-C) levels in patients with gout. Serum triglyceride levels were significantly higher in patients with gout than in normal subjects. In contrast, serum levels of HDL-C and HDL2-C were significantly lower in patients with gout than in normal subjects. These results were further analysed using stepwise logistic regression. This analysis demonstrated that both serum triglyceride levels and alcohol consumption discriminated subjects with gout from controls but BMI, HDL-C and HDL2-C did not, suggesting that increased serum triglyceride levels exist intrinsically in gout, while decreased concentrations of HDL-C and HDL2-C may be attributed to hypertriglyceridaemia.

Niacin has been used for many years to treat hyperlipidemia. It has been shown to reduce coronary death and non-fatal myocardial infarction and, in a separate analysis of long-term (15-year) follow-up, all cause mortality. It reduces total cholesterol, low density lipoprotein cholesterol (LDL-C) and triglycerides and increases high density lipoprotein cholesterol (HDL-C). Sustained-release niacin may be associated with more dramatic changes in LDL-C and triglyceride, whereas the short acting preparation causes greater increases in HDL-C. The increase of HDL-C occurs at a lower dose (1500 mg/day) than the reduction of LDL-C (> 1500 mg/day). Niacin also favorably influences other lipid parameters including lipoprotein(a) [Lp(a)], alimentary lipemia, familial defective apolipoprotein B-100 and small dense LDL. Combination of niacin with a bile acid sequestrant or a reductase inhibitor represents a powerful lipid-altering regimen. Whereas the reductase inhibitors and bile acid binding resins primarily affect LDL-C, the combined therapy has a synergistic effect to reduce LDL-C and, in addition, the niacin reduces triglycerides and increases HDL-C. The major drawback in the use of niacin is associated side effects (flushing and palpitations) and toxicity (worsening of diabetes control, exacerbation of peptic ulcer disease, gout, hepatitis). Niacin has a long history of use as a lipid lowering agent and has several attractive features. Unfortunately, the side effect profile of this agent warrants its use only in patients with marked dyslipidemia in whom side effects and potential toxicity are closely monitored.

Background Bempedoic acid (BA) is a novel lipid-lowering drug. We performed a systematic review and meta-analysis on efficacy and safety of BA compared with standard treatment in patients with hypercholesterolemia. Methods and Results Studies were systematically searched in the PubMed, Web of Science, Scopus, and EMBASE databases. Efficacy outcome was represented by percentage changes (mean difference [MD] with pertinent 95% CIs) in total cholesterol, low-density lipoprotein cholesterol, triglycerides, high-density lipoprotein cholesterol, apolipoprotein B, non-high-density lipoprotein cholesterol, and hs-CRP (high-sensitivity C-reactive protein) in BA patients and controls. Seven studies were included (2767 BA-treated patients and 1469 controls), showing a more significant reduction in low-density lipoprotein cholesterol (MD, -17.5%; 95% CI, -22.9% to -12.0%), total cholesterol (MD, -10.9%; 95% CI, -13.3% to -8.5%), non-high-density lipoprotein cholesterol (MD, -12.3%; 95% CI, -15.3% to -9.20%), apolipoprotein B (MD, -10.6%; 95% CI, -13.2% to -8.02%), and hs-CRP (MD, -13.2%; 95% CI, -16.7% to -9.79%) in BA-treated patients compared with controls. Results were confirmed when separately analyzing studies on patients with high cardiovascular risk, studies on statin-intolerant patients, and studies on patients with hypercholesterolemia on maximally tolerated lipid-lowering therapy. BA-treated subjects reported a higher rate of treatment discontinuation caused by adverse effects, of gout flare, and of increase in uric acid compared with controls. On the other hand, BA-treated patients showed a lower incidence of new-onset diabetes mellitus than controls. Conclusions BA is associated with a significant reduction in low-density lipoprotein cholesterol, total cholesterol, non-high-density lipoprotein cholesterol, apolipoprotein B, and hs-CRP compared with standard treatment. Documented efficacy is accompanied by an acceptable safety profile.
