1. We established a new animal model of metabolic syndrome, SHRSP fatty (fa/fa) rats, by crossing stroke-prone spontaneously hypertensive rats of the Izumo strain (SHRSP/Izm) to Zucker fatty (ZF) (fa/fa) rats. 2. The SHRSP fatty (fa/fa) rats have a missense mutation of the leptin receptor gene and plasma leptin concentrations are augmented. The SHRSP fatty (fa/fa) rats develop obesity and hypertension simultaneously. 3. Plasma metabolic parameters, including glucose, insulin and total cholesterol and triglyceride levels, were markedly elevated in SHRSP fatty (fa/fa) rats compared with SHRSP/Izm rats. Plasma triglyceride concentrations in SHRSP fatty (fa/fa) rats were significantly elevated compared with those in ZF (fa/fa) rats. The weight of adipose tissues in SHRSP fatty (fa/fa) rats was greater than that of SHRSP/Izm rats. The phenotype of SHRSP fatty (fa/fa) rats is similar to that of human metabolic syndrome.

Diabetes mellitus is a serious problem that will soon reach epidemic proportions in the United States and throughout the world. The incidence of this condition will skyrocket in the next quarter century as demographic changes increase the size of highly susceptible populations (e.g., the elderly and Hispanic communities) and sociocultural developments create a more sedentary populace as well as expose people in developing nations to new risk factors for this disease. Along with substantial direct morbidity and mortality, diabetes is independently associated with the incidence and severity of a variety of cardiovascular illnesses. Individuals with diabetes are substantially more likely than their nondiabetic counterparts to suffer stroke, myocardial infarction, or heart failure, with a worse prognosis following any of these conditions. Many factors may be relevant to this association, but recent studies have elucidated a major role for the metabolic syndrome, which has been shown to be predictive of both diabetes and cardiovascular disease. Consequently, early intervention to control blood glucose levels and other risk factors may mitigate the severity of these conditions, possibly even before the disease begins.

The prospective associations between the metabolic syndrome as defined by the National Cholesterol Education Program (NCEP/ATP III) expert panel and mortality from cardiovascular disease and all-causes has not been extensively examined. Using data from the National Health and Nutrition Examination Survey II Mortality Study (1976-1992), the author examined the association between the metabolic syndrome and mortality from all-causes and cardiovascular disease among 2431 US adults aged 30-75 years. The NCEP/ATP III criteria were modified to substitute body mass index >/=25 kg/m(2) for waist circumference for women and >/=30 kg/m(2) for men. After multiple-adjustment, the hazard ratios for participants with the metabolic syndrome were 1.37 (95% confidence interval (CI): 1.02, 1.85) for mortality from cardiovascular disease, 1.29 (95% CI: 0.92, 1.82) for mortality from coronary heart disease, 1.68 (95% CI: 0.86, 3.27) for mortality from stroke, 1.23 (95% CI: 0.95, 1.59) for mortality from diseases of the circulatory system, and 1.15 (95% CI: 0.92, 1.45) for all-cause mortality compared with participants without the syndrome. The association between the number of metabolic syndrome criteria and mortality from cardiovascular disease was near linear (P = 0.007). Three criteria of the syndrome-excess weight, hypertriglyceridemia, and low high-density lipoprotein cholesterol concentration-were not independently associated with any of the outcomes. Additional prospective studies are needed to examine the association between the metabolic syndrome and the incidence of cardiovascular disease and mortality from cardiovascular disease and all-causes.

Hyperuricemia (HU) is present in 5-30% of the general population, although the prevalence is higher among some ethnic groups and seems to be increasing worldwide. Classically, chronic HU has been considered a risk factor for gout or lithiasis and is associated with alcoholism, obesity, hypertension, dyslipidemia, hyperglycemia/diabetes mellitus, renal failure and intake of certain drugs. HU is also associated with cardiovascular diseases such as hypertension, vascular disease, pre-eclampsia, pulmonary arterial hypertension, stroke, heart failure, ischemic heart disease and also metabolic syndrome, renal disease and increased mortality. It is uncertain if these associations are dependent or not, especially cardiovascular and renal diseases. Patients with chronic HU and also those with gout require both medical investigation for associated diseases or drugs as well as nutritional counseling and life-style changes. HU should alert physicians to possible complications.

Numerous studies have demonstrated that increased C-reactive protein (CRP) levels predict coronary heart disease, stroke, peripheral vascular disease, and diabetes, and are associated with features of the metabolic syndrome. Only three previous studies have investigated the heritability of CRP levels, primarily in samples of Caucasian families. The purpose of the present study was to estimate the magnitude of genetic influences on CRP levels, and to examine potential associations between variation in the APOE gene and CRP levels, using a sample of 562 individual Japanese Americans from 68 extended kindreds. In general, correlation coefficients between first-degree relatives for CRP were approximately 0.2, and spouse correlations did not differ from zero, consistent with genetic influences. Heritability estimates were approximately 0.3 (p < 0.01), even with adjustment for factors known to influence CRP levels. A significant relationship was seen between unadjusted CRP levels and APOE genotypes (p = 0.02), with the highest mean CRP level among epsilon2 carriers (1.20 mg/L), and nearly the same mean levels among epsilon3/epsilon3 subjects and epsilon4 carriers (0.72 and 0.74 mg/L, respectively). However, this relationship was diminished with adjustment for covariates (p = 0.07). These results demonstrate the presence of both genetic and environmental effects on CRP levels among Asian Americans, and additional studies are needed to determine if the APOE gene contributes to these genetic influences.

The insulin resistance syndrome (syndrome X, metabolic syndrome) has become the major health problem of our times. Associated obesity, dyslipidemia, atherosclerosis, hypertension, and type 2 diabetes conspire to shorten life spans, while hyperandrogenism with polycystic ovarian syndrome affect the quality of life and fertility of increasing numbers of women. Whereas a growing number of single genetic diseases affecting satiety or energy metabolism have been found to produce the clinical phenotype, strong familial occurrences, especially in racially prone groups such as those from the Indian subcontinent, or individuals of African, Hispanic, and American Indian descents, together with emerging genetic findings, are revealing the polygenetic nature of the syndrome. However, the strong lifestyle factors of excessive carbohydrate and fat consumption and lack of exercise are important keys to the phenotypic expression of the syndrome. The natural history includes small for gestational age birth weight, excessive weight gains during childhood, premature pubarche, an allergic diathesis, acanthosis nigricans, striae compounded by gynecomastia, hypertriglyceridemia, hepatic steatosis, premature atherosclerosis, hypertension, polycystic ovarian syndrome, and focal glomerulonephritis appearing increasingly through adolescence into adulthood. Type 2 diabetes, which develops because of an inherent and/or an acquired failure of an insulin compensatory response, is increasingly seen from early puberty onward, as is atheromatous disease leading to coronary heart disease and stroke. A predisposition to certain cancers and Alzheimer's disease is also now recognized. The looming tragedy from growing numbers of individuals affected by obesity/insulin resistance syndrome requires urgent public health approaches directed at their early identification and intervention during childhood. Such measures include educating the public on the topic, limiting the consumption of sucrose-containing drinks and foods with high carbohydrate and fat contents, and promoting exercise programs in our nation's homes and schools.

Regional body fat distribution has an important influence on metabolic and cardiovascular risk factors. Increased abdominal (visceral) fat accumulation is a risk factor for coronary artery disease (CAD), dyslipidemia, hypertension, stroke, and type 2 diabetes. The recent emphasis on treatment of the dyslipidemia of the metabolic syndrome (hypertriglyceridemia, reduced high-density lipoprotein, and increased small, dense low-density lipoprotein particle number) has compelled practitioners to consider lipid-lowering therapy in a greater number of their patients, as one in two individuals over age 50 has the metabolic syndrome. Individuals with the metabolic syndrome typically have normal low-density lipoprotein cholesterol levels, and current lipid-lowering guidelines may underestimate their cardiovascular risk. Two subgroups of patients with the metabolic syndrome are at particularly high risk for premature CAD. One, individuals with type 2 diabetes, accounts for 20-30% of early cardiovascular disease. The second, familial combined hyperlipidemia, accounts for an additional 10-20% of premature CAD. Familial combined hyperlipidemia is characterized by the metabolic syndrome in addition to a disproportionate elevation of apolipoprotein B levels. The measurement of fasting glucose and apolipoprotein B, in addition to the fasting lipid profile, can help to estimate CAD risk in patients with the metabolic syndrome.

Type 2 diabetes mellitus (DM) has traditionally been considered a disease of adults. However, in the last 2 decades, it is increasingly being reported in children and adolescents. Obesity is a strong correlate, and the increasing prevalence of obesity and poor physical activity is precipitating type 2 DM at younger ages in the ethnic groups at risk. Indians and other South Asians are among the ethnic groups particularly prone to insulin resistance and type 2 DM, the other racial groups being some American Indian tribes like the Pima Indians, Mexican Americans,Pacific Islanders and African Americans,among others. The WHO has predicted that India will have the greatest number of diabetic individuals in the world by the year 2025. Type 2 DM starting during adolescence puts the individual at risk for major morbidity and even mortality right during the productive years of life. The microvascular complications of DM (nephropathy, retinopathy, neuropathy) are brought on at an early age. In addition, type 2 DM and obesity are two components of a metabolic syndrome of insulin resistance, the other features of which include hypertension, dyslipidemia and hypercoagulability of blood. All these conditions together increase the risk for cardiovascular and cerebrovascular mortality and morbidity (i.e., myocardial infarction and stroke). The resulting economic burden will be enormous. Type 2 DM and the insulin resistance syndrome are to a large extent preventable. Adoption of a healthy eating and physical activity pattern has resulted in decreasing the development of DM in a few recent studies from various parts of the world. A concerted,multi-pronged effort is needed, involving the general public, pediatricians and general physicians, teachers and schools, the media,the government and professional medical bodies, to generate a momentum towards the goal of prevention of type 2 DM and the insulin resistance syndrome in the young population of India.

Type 2 diabetes plays significant roles in pathogenesis of metabolic syndrome. The Japan Diabetes Complications Study(JDCS) is an ongoing trial with 2,205 patients with type 2 diabetes. It is clarified that the frequencies of CHD and stroke events in type 2 diabetic patients are three or more times greater than non-diabetic subjects. Gender, LDL cholesterol, glycohemoglobin A1c and triglycerides are significant age-adjusted risk factors for CHD in patients with type 2 diabetes, while systolic blood pressure and glycohemoglobin A1c are those for stroke. We can conclude from these results that the control of risk factors like LDL cholesterol and blood pressure, together with glycemic control, is essential for preventing CHD and stroke also in Japanese patients with type 2 diabetes.

High-sensitivity C-reactive protein (hsCRP) is a marker of inflammation that predicts incident myocardial infarction, stroke, peripheral arterial disease, and sudden cardiac death among healthy individuals with no history of cardiovascular disease, and recurrent events and death in patients with acute or stable coronary syndromes. hsCRP confers additional prognostic value at all levels of cholesterol, Framingham coronary risk score, severity of the metabolic syndrome, and blood pressure, and in those with and without subclinical atherosclerosis. hsCRP levels of less than 1, 1 to 3, and greater than 3 mg/L are associated with lower, moderate, and higher cardiovascular risks, respectively. This article summarizes epidemiologic data on the relation between CRP and atherothrombotic disease and provides clinical guidelines for hsCRP screening in cardiovascular risk assessment.
