The 10-year follow-up of the Munich General Practitioner Project was designed as a long-term prospective study to evaluate factors predicting macrovascular and overall mortality in a random cohort of non-insulin-dependent diabetic (NIDDM) patients. Of the original 290 patients (103 males, 187 females, median age 65 years) 92.5% could be assessed, 103 subjects had died, 58 from macrovascular causes. In an univariate analysis of baseline data, deceased patients, and especially those who died from macrovascular causes had significantly higher fasting blood glucose, HbA1c, von Willebrand-factor protein, urine albumin excretion, and serum beta 2-microglobulin, were significantly older, exhibited significantly more ischaemic heart disease (abnormal ECG Minnesota codes), carotid artery and peripheral vascular disease (both determined by ultrasound-Doppler), and had significantly inferior knowledge about diabetes and its treatment. No significant differences were seen for gender, blood pressure, smoking, total cholesterol, triglycerides, HDL-cholesterol, or the use of antidiabetic, antihypertensive or coronary drugs. In a multiple logistic regression analysis, the risk factors for macrovascular death were age, HbA1c and von Willebrand-factor protein. When baseline macrovascular disease was taken into account, carotid artery disease was also a determinant. The main variables from the metabolic syndrome (blood pressure, dyslipidaemia, body mass index) did not enter a multiple logistic regression analysis. The data suggest that age and haemoglobin A1c are major determinants, and that in addition von Willebrand-factor associated endothelial damage is a risk factor for macrovascular mortality in NIDDM patients.

In NIDDM a clustering of established coronary risk factors, e.g. the metabolic syndrome is responsible for excessive incidence of myocardial infarction. The harmful effects of these risk factors are aggravated by poor glucose control. Hyperinsulinaemia is associated with a higher level of risk factors for coronary heart disease. Individuals with subsequent myocardial infarction exhibit higher levels of serum insulin at entry. However, insulin in multivariate analysis was no independent risk factor. Perfect control of blood glucose, triglycerides and blood pressure was associated with a lower incidence of coronary heart disease. By extrapolation an integrated approach to correct the anomalies of the metabolic syndrome seems to be necessary to prevent macroangiopathy and improve life expectancy.

Recently, an inverse correlation between serum uric acid concentrations and insulin sensitivity has been described in subjects with varying degrees of metabolic syndrome, suggesting that measurement of serum uric acid may provide a simple marker of insulin resistance. Several biochemical and clinical features of polycystic ovary syndrome (PCOS) resemble those of metabolic syndrome: women with PCOS are often obese; they are also at increased risk for the development of coronary artery disease, hypertension and diabetes mellitus. The objective of the present study was to analyse the usefulness of serum uric acid measurement in screening for the metabolic syndrome in women with PCOS. For that purpose serum concentrations of uric acid, insulin and triglycerides were measured in 38 women with PCOS and 20 weight-matched control women with regular menstrual cycles. No differences were found in the uric acid concentrations between the PCOS and control groups. The mean concentrations of triglycerides and fasting insulin were higher in the women with PCOS than in the healthy controls. Serum uric acid concentrations were inversely related to serum hormone-binding globulin (SHBG) concentrations, and positively with body mass index (BMI), insulin concentrations and testosterone:SHBG ratio in the PCOS group. Our results suggest that measurement of serum uric acid does not provide new means for identification of metabolic syndrome in patients with PCOS.

A group of metabolic disorders including insulin resistance and hyperinsulinemia, impaired glucose tolerance, visceral obesity, hypertension, dyslipidemia, hyperuricemia, hypercoagulability and microalbuminuria determine the risk for the development of atherosclerosis, coronary artery disease and cerebral vascular disorders. Although available studies on the pathogenesis of the metabolic syndrome are equivocal, it is most frequently hypothesized that hereditary of insulin resistance leads to the remaining metabolic disorders including diabetes mellitus, atherosclerosis and coronary artery disease. Despite pathogenetic controversies, there are convincing arguments for the diagnosis of the metabolic syndrome and search for therapy improving insulin sensitivity and reducing hyperinsulinemia thus preventing the development of diabetes mellitus and coronary artery disease.

Metabolic syndrome is characterized by a large number of metabolic disorders, the findings being generally a combination of insulin resistance, obesity, hypertension, dislipidemia and pathological glucose tolerance or diabetes mellitus type II. Metabolic syndrome is diagnosed too seldom in view of the fact that a prevalence of at least 10% must be assumed for the population as a whole. Besides genetic predisposition, environmental factors such as diet, physical inactivity and nicotine and alcohol consumption play a decisive role in its clinical manifestation. The paper briefly examines the pathophysiological connections between the individual findings, with the central role of insulin resistance being emphasized. With a multifactorial therapy, in which non-medicamentous treatment is predominant, it must be assumed that on the whole compliance will tend to be poor. Prognostically the syndrome is serious, very frequently resulting in premature atherosclerosis. The paper concludes with a consideration of the underwriting of metabolic syndrome, one of the points being that the extramortality rates of the individual impairments should not be applied additively.

Noninsulin-dependent diabetes mellitus is a genetically determined form of diabetes, due to impaired insulin secretion by the B-cells as well as to insulin resistance of the peripheral tissues. According to the glucose toxicity theory hyperglycemia and hyperinsulinemia exist in a vicious circle. Therefore, it is a major therapeutical aim to put the B-cell to rest and improve insulin sensitivity by a strict control of fasting blood glucose and of postprandial hyperglycemia. Furthermore, associated abnormalities within the metabolic syndrome, such as hypertension, dyslipoproteinemia and hemostatic disorders should be corrected to avoid vessel complications. Therefore, it should be started with basic measures as body weight reduction, carbohydrate-rich and fat-poor diet and exercise. If these measures fail to achieve acceptable glycemic control, antihyperglycemic drugs (acarbose, metformin) are indicated, eventually in a combination with small doses of short-acting sulfonylureas. Further impairment of insulin secretion is the indication for sulfonylurea and/or insulin application. HbA1c of 7 to 7.5% should be the goal of antidiabetic therapy, also for patients in advanced age. The main criterion for the choice of antidiabetics is the present insulin secretion capacity. Simple indicators in this respect are changes of body weight, plasma triglycerides and C-Peptide after i.v. glucagon stimulation. Application of insulin in combination with other antidiabetics or in the form of intensified insulin therapy should not be too much postponed.

The metabolic syndrome consists of a cluster of metabolic diseases which often coexist: abdominal obesity, glucoseintolerance, diabetes mellitus type II, dyslipidemia, hypertension and impaired fibrinolysis. The common pathophysiologic link of these diseases in insulin resistance. All clinical disorders of the metabolic syndrome are risk factors for the vascular system. Since several diseases are present at the same time the risk for atherosclerotic complications such as coronary artery disease and apoplexy is potentiated. As a consequence the costs for direct and indirect health care are high. Besides a genetic predisposition the metabolic syndrome is mainly caused by the typical life style in industrialized countries with high energy and fat intake, physical inactivity, alcohol consumption, smoking, and stress. Therefore, prophylaxis and therapy imply the removal of these factors. In order to be successful experienced physicians and motivated patients are prerequisites. Even more affective than therapy is prophylaxis which is, however, not established in Germany. The metabolic syndrome is up to now not identified as a major health problem neither by the medical profession nor by health insurances and politicians. An effective therapy and prophylaxis would induce far-reaching changes in our health system and diminish health costs.

Abnormal liver tests, as well as morphological changes in the liver, are frequent among obese patients. Other frequent disturbances are visceral fat accumulation, insulin resistance, non-insulin-dependent diabetes mellitus (NIDDM), hypertriglyceridemia, and hypertension; these are set of aberrations known as the metabolic syndrome. In order to investigate a possible relationship between the metabolic syndrome and impaired liver status we examined associations between liver tests, metabolic variables (insulin, glucose, and triglycerids), body composition and nutrition in 1,083 men (BMI 28.8-63.8 kg/m2) and 1,367 women (BMI 26.7-68.0 kg/m2) in the ongoing intervention study of Swedish Obese Subjects (SOS). Standard biochemical techniques were used to assess liver status and metabolic variables. Lean body mass (LBM) and masses of visceral and subcutaneous adipose tissue (AT) were estimated by means of computed tomography (CT) calibrated anthropometric equations. In both genders aspartate aminotransferase and alanine aminotransferase were, or tended to be, positively correlated to fasting serum insulin, visceral AT (women), and alcohol intake. In women, the aminotransferases were also correlated with fasting blood glucose. In both genders alkaline phosphatase was, or tended to be, positively associated with visceral AT, insulin (women), and glucose. Bilirubin was negatively correlated to insulin and visceral AT in men and women. Additional multivariate analyses indicated that alcohol had less explanatory power than serum insulin for the examined liver tests, especially among women. These results suggest that pathological liver tests in the obese may represent an expression of the metabolic syndrome.

The association of a parental history of diabetes mellitus and hypertension with the multiple metabolic syndrome (MMS) was studied in a population survey of middle-aged adults. The eligible population was drawn from the baseline examination of the Atherosclerosis Risk in Communities Study, a population-based, bi-ethnic, multi-centre cohort study. The MMS was defined as a multivariate, categorical phenotype of co-occurring diabetes, hypertension, and dyslipidaemia. MMS cases (n = 356) were compared to disorder-free control subjects (n = 6797) with respect to their parental history of diabetes and hypertension. MMS cases were more likely to report a history of diabetes in both parents (odds ratio [OR] 4.7, 95 % confidence interval (CI) 1.5-14.7) or a history of hypertension in both parents (OR 1.9, 95 % CI 1.1-3.0) than control subjects, adjusting for BMI, waist-to-hip ratio, age, gender, and ethnicity/centre. A parental history of diabetes and hypertension in both parents was associated with the greatest increase in odds of MMS (OR 8.3, 95 % CI 3.0-22.8). A dose-response relationship between the number of parental disorders (one; two; three to four) and the odds of MMS was observed (OR 1.2, 95 % CI 0.9-1.7; OR 2.0, 95 % CI 1.4-2.8; OR 4.0, 95 % CI 2.5-6.2). Based on the marked associations observed between a parental history of MMS components and the clustering of these metabolic disorders in the offspring generation, we conclude that genetic and/or non-genetic familial influences play a role in the development of the multiple metabolic syndrome.

We evaluated venous plasma ET-1 concentrations in 18 never-treated obese men (body mass index 31.0 +/- 0.5 kg/m2; age 45.4 +/- 4.3 years) showing the whole features of the above syndrome and 12 control men (age 44.1 +/- 3.6 years). Circulating ET-1 levels were significantly higher in patients than in controls (p < 0.05), and were directly correlated with fasting insulin levels (r = 0.564, p = 0.015) and erythrocyte Na+/Li+ counter-transport activity (r = 0.504, p = 0.033). In conclusion, venous plasma ET-1 levels are elevated in obese men manifesting the whole features of the metabolic syndrome. Due to the biological properties of ET-1, our findings suggest the peptide as a further component of the cluster of cardiovascular risk factors which characterizes this syndrome.
