The incidence of cardiovascular disease is four to five times greater in people with diabetes than in people without diabetes. Lipid disorders, along with elevated blood pressure, cigarette smoking, and abdominal obesity, are major risk factors for people with diabetes. All adults with diabetes should be screened for blood lipid levels including triglycerides, cholesterol, and high-density lipoprotein (HDL) cholesterol. The low-density lipoprotein (LDL) cholesterol should be measured more routinely in people with diabetes than suggested in the National Cholesterol Education Project (NCEP) guidelines. No single diet is best for persons with diabetes. Sometimes a lower fat, higher carbohydrate diet is more acceptable, and other times a lower carbohydrate, higher monounsaturated fatty acid (MUFA) diet is preferred. The decision regarding the level of fat in the diet is based both on patient preference as well as serial measurements of metabolic control. Changing eating habits regarding lipids is a gradual process and can best be accomplished when introduced in a staged approach.

Patients with combined dyslipidemia are at high risk for coronary artery disease and often require combination drug therapy to achieve lipid levels recommended by the US National Cholesterol Education Program's third Adult Treatment Panel (ATP III). In addition to recommendations for low-density lipoprotein (LDL) cholesterol and triglyceride levels, ATP III established non-high-density lipoprotein (HDL) cholesterol goals for individuals with triglycerides >or=2.26 mmol/L (>or=200 mg/dL). It also introduced certain criteria for the diagnosis of the metabolic syndrome, a clustering of risk factors (abdominal obesity, elevated triglycerides, low HDL cholesterol, elevated blood pressure, impaired fasting glucose) that increases cardiovascular risk and is common in patients with combined dyslipidemia. Statin monotherapy has been shown to benefit these patients, and additional benefit may be obtained by combination therapy that provides greater reductions in both LDL cholesterol and triglycerides as well as greater increases in HDL cholesterol. However, combining a statin with either niacin or a fibrate may increase the risk for myopathy and therefore requires careful monitoring and evaluation of the risk-benefit ratio for each patient. Moreover, combination therapy may be associated with increased drug costs and decreased patient compliance. Recently developed agents that may improve the effectiveness of combination therapy include ezetimibe-a cholesterol absorption inhibitor-and a formulation that combines extended-release niacin and lovastatin in a single pill. Clinical trials are needed to determine the optimal treatment in patients with combined dyslipidemia.

Considerable data on the pathophysiology, epidemiology, and treatment of dyslipidemia-induced coronary heart disease (CHD) have accumulated in recent years. These data have been assessed and incorporated into the guidelines of the National Cholesterol Education Program Expert Panel on the Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel [ATP] III). A major focus of the new guidelines is the assessment of the near-term (i.e., 10-yr) risk of experiencing a CHD event and matching the intensity of treatment to this risk. Patients with diabetes and those with a greater than 20% 10-year risk of experiencing a CHD event have been elevated to the risk level of CHD equivalent. The ATP III guidelines also modify several lipid and lipoprotein classifications. A low-density lipoprotein cholesterol (LDL) level below 100 mg/dl is now considered optimum for all individuals. In addition, high-density lipoprotein cholesterol (HDL) and triglyceride cutoff points have been modified to reflect more accurately the risk associated with abnormalities in these lipoproteins. As with the previous guidelines, the primary target of therapy remains LDL. Therapeutic lifestyle changes consisting of diet, weight reduction, and increased physical activity should be included in all treatment regimens. Based on their potent LDL-lowering properties and their proven ability to decrease mortality in a variety of patient populations, statins are generally the first choice for pharmacologic therapy. A secondary target of therapy includes non-HDL goals for patients with high triglyceride levels and the metabolic syndrome, which is characterized by abdominal obesity, elevated triglyceride levels, low HDL levels, and insulin resistance. Management of these secondary targets includes weight reduction and increased physical activity, and treatment of the lipid and nonlipid risk factors. Overall, ATP III represents an aggressive approach to treating dyslipidemia, greatly extending the number of individuals who qualify for treatment.

The metabolic syndrome (MS) is a frequent cause of coronary artery disease (CAD), and recently the National Cholesterol Education Program Adult Treatment Panel III suggested its diagnosis in the presence of 3 to 5 quantitatively defined markers. Because the consequences of the MS are likely related to the number and diversity of markers, we studied the relation between the number of markers-the MS score-and the degree of abdominal obesity, risk factor profile, and severity of CAD. One thousand one hundred eight subjects of a mostly white population with symptoms of CAD (793 men and 315 women; 58.1 +/- 9.8 years of age) were divided into 6 groups based on their MS scores. A low high-density lipoprotein cholesterol level was the most frequently observed marker, followed by increased blood pressure, triglycerides, waist circumference, and fasting glucose. As the MS score increased so did abdominal obesity, parameters of "nontraditional" dyslipidemia with surrogate markers of dense low-density lipoprotein and high-density lipoprotein particles, blood pressure, fasting glucose, insulin, and the homeostatic model assessment insulin resistance index. Similarly, an increasing MS score was significantly related to more severe coronary angiographic alterations and higher frequencies of unstable angina, myocardial infarction, percutaneous coronary intervention, and coronary artery bypass grafting. Therefore, the MS score provides a clinically useful index of MS severity and the associated atherosclerotic risk factor profile. It also correlates with the angiographic severity of CAD and its clinical complications.

The metabolic syndrome, recognized by the co-occurrence of general or abdominal obesity, hypertension, dyslipidemia, insulin resistance, and dysglycemia, appears to involve disturbances in metabolism, autonomic function, and health-related behaviors. However, physiological processes linking the components of the metabolic syndrome remain obscure. The current study examined associations of central nervous system serotonergic function with each metabolic syndrome risk variable, the metabolic syndrome, and physical activity. The subjects were 270 adult volunteers who participated in a study of cardiovascular disease risk factors and neurobehavioral functioning. Central serotonergic responsivity was indexed as the prolactin (PRL) response evoked by the serotonin-releasing agent, fenfluramine. Across the sample, low PRL response was associated with greater body mass index, higher concentrations of triglycerides, glucose, and insulin, higher systolic and diastolic blood pressure, greater insulin resistance, and less physical activity (P < 0.03-0.001). There also existed an inverse linear relationship between PRL response and the number of metabolic syndrome risk factors individuals possessed (P for trend = 0.002). Finally, a 1 SD decline in PRL response was associated with an odds ratio for the metabolic syndrome of 2.05 (95% confidence interval, 1.10-3.83; P = 0.002) and 5.70 (95% confidence interval, 1.69-19.25; P = 0.005), according to the definitions of the National Cholesterol Education Program and the World Health Organization, respectively. These findings reveal a heretofore unrecognized association between reduced central serotonergic responsivity and the metabolic syndrome.

Obesity is a major risk factor for several metabolic diseases, frequently clustering to form the metabolic syndrome, carrying a high risk of cardiovascular mortality. We aimed to assess the prevalence of the metabolic syndrome in treatment-seeking obese subjects and the potential protective effect of physical activity. A cross-sectional analysis of data from a large Italian database of treatment-seeking obese subjects was performed. The metabolic syndrome was defined according to the criteria provisionally set by the National Cholesterol Education Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults, based on waist circumference, fasting glucose, triglyceride (TG) and high-density lipoprotein-cholesterol (HDL-C) levels, and arterial pressure. Data were available in 1,889 Caucasian subjects, 78% females, from 25 obesity centers. Minimum criteria for the metabolic syndrome were fulfilled in 53% of cases. The prevalence increased with age and obesity class and was negatively associated with participation in a structured program of physical activity (odds ratio, 0.76; 0.58 to 0.99; P =.041), after correction for age, sex, and body mass. The prevalence of cardiovascular disease was higher in subjects with the metabolic syndrome. A subset of 12.8% of cases had no metabolic abnormalities. They had a lower prevalence of abdominal obesity and cardiovascular disease. Isolated obesity was significantly associated with physical activity (odds ratio, 1.86; 1.33 to 2.60; P =.0003). Multiple metabolic disorders are present in most obese patients, and their prevalence is lower in physically active subjects. It is time to move towards a more integrated approach and to reconsider resource allocation to improve lifestyle changes for large-scale control of obesity.

The metabolic syndrome is intended to identify patients who have increased risk of diabetes and/or a cardiac event due to the deleterious effects of weight gain, sedentary lifestyle, and/or an atherogenic diet. The National Cholesterol Education Program's Adult Treatment Panel III definition uses easily measured clinical findings of increased abdominal circumference, elevated triglycerides, low high-density lipoprotein-cholesterol, elevated fasting blood glucose and/or elevated blood pressure. Three of these five are required for diagnosis. The authors also note that other definitions of metabolic syndrome focus more on insulin resistance and its key role in this syndrome. This review focuses on how treatment might affect each of the five components. Abdominal obesity can be treated with a variety of lower calorie diets along with regular exercise. Indeed, all of the five components of the metabolic syndrome are improved by even modest amounts of weight loss achieved with diet and exercise. For those with impaired fasting glucose tolerance, there is good evidence that a high fiber, low saturated fat diet with increased daily exercise can reduce the incidence of diabetes by almost 60%. Of note, subjects who exercise the most, gain the most benefit. Metformin has also been shown to be helpful in these subjects. Thiazolidinedione drugs may prove useful, but further studies are needed. Although intensified therapeutic lifestyle change will help the abnormal lipid profile, some patients may require drug therapy. This review also discusses the use of statins, fibrates, and niacin. Likewise, while hypertension in the metabolic syndrome benefits from therapeutic lifestyle change, physicians should also consider angiotensin converting enzyme inhibitor drugs or angiotensin receptor blockers, due to their effects on preventing complications of diabetes, such as progression of diabetic nephropathy and due to their effects on regression of left ventricular hypertrophy. Aspirin should be considered in those with at least a 10% risk of a coronary event over 10 years. Finally, three related conditions, nonalcoholic fatty liver disease, polycystic ovary syndrome and protease inhibitor associated lipodystrophy improve with therapeutic lifestyle change. Although metformin is shown to be useful with polycystic ovary syndrome, the data supporting drug therapy for the other syndromes is less convincing. More robust studies are needed before any firm recommendations can be made.

The National Cholesterol Education Program's Adult Treatment Panel III identifies persons with multiple metabolic risk factors or "metabolic syndrome" as candidates for intensified therapeutic lifestyle changes. This article reviews the important role of weight reduction,diet, and exercise in improving the metabolic syndrome and its risk factors of abdominal obesity, impaired fasting glucose,dyslipidemia, and coagulation/inflammatory factors. The article also provides practical strategies.

Genetic factors, alone or in interaction with components of the diet, are thought to be involved in the development of the metabolic syndrome. The objective of our study was first to compare the frequency of the peroxisome proliferator-activated receptor (PPAR)alpha-L162V polymorphism in a sample of men with and without the metabolic syndrome as defined by the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATPIII) guidelines, and secondly, to evaluate gene-diet interaction effects on features of the metabolic syndrome. The PPARalpha-L162V genotype was determined in a sample of 632 men by a polymerase chain reaction-restriction length polymorphism (PCR-RFLP)-based method; fat as well as saturated fat intakes were evaluated by a dietitian-administered food frequency questionnaire. The frequency of the V162 allele was similar in men with ( n=281) and without ( n=351) the metabolic syndrome ( chi(2)=0.03, p=0.84) but was higher in subjects having simultaneously abdominal obesity, hypertriglyceridemia, and low high-density lipoprotein cholesterol (HDL-C) levels ( chi(2)=3.73, p=0.05). Carriers of the V162 were characterized by higher plasma apolipoprotein B and triglyceride (TG) levels ( p=0.10, p=0.004). In a model including the PPARalpha-L162V polymorphism, fat or saturated fat, its interaction, and covariates (smoking habits, and energy and alcohol intake), the interaction explained a significant percentage of the variance observed in waist circumference ( p<0.05). In conclusion, the PPARalpha-L162V polymorphism alone or in interaction with dietary fat intake is associated with components of the metabolic syndrome.

Recent definitions of the metabolic syndrome from the World Health Organization (WHO) and National Cholesterol Education Program (NCEP) have given us a clearer picture of the prevalence of the metabolic syndrome and the risks it poses for cardiovascular disease and type 2 diabetes. Solid epidemiological and trial evidence support lifestyle changes as the main modifiable risk factors, including abdominal obesity, sedentary lifestyle and a diet rich in saturated fat and low in fiber content, in the treatment of individual components of the metabolic syndrome. Physical activity may prevent the metabolic syndrome as defined by the WHO and NCEP, but the evidence for lifestyle changes using these definitions is still sparse. No trials on the treatment of the metabolic syndrome to prevent diabetes have been published. However, both the Finnish Diabetes Prevention Study and the Diabetes Prevention Program found that moderate lifestyle interventions in persons with impaired glucose tolerance, a condition related to the metabolic syndrome. decreased the incidence of type 2 diabetes by 58%. Some drugs may also prevent diabetes. Further research on lifestyle modifications in the prevention and treatment of the metabolic syndrome, and on how best to promote lifestyle changes, is needed. In the meantime, efforts to curb obesity and overweight, increase physical activity and improve compliance with current dietary recommendations should continue.
