Total cholesterol levels, obesity index and blood pressure were measured in 6,278 school-age children living in Ibaraki Prefecture in 1991, and children with high risk for atherosclerosis were identified. The frequencies of the school-age children with hypercholesterolemia (total cholesterol > or = 200 mg/dl), obesity (obesity index > or = 40%) or hypertension were 7%, 5%, 1%, respectively. In half of the area where the children lived, lipid measurements were also obtained in the parents of hypercholesterolemic children. Twenty-nine out of ninety fathers (32%) and 22 out of 140 mothers (16%) were hypercholesterolemia (total cholesterol > or = 240 mg/dl). Among them five families of familial hypercholesterolemia were diagnosed. Seventy children with hypercholesterolemia and 81 obese children, who were screened and received health counseling, were re-examined after one year. The levels of LDL-cholesterol, triglyceride and atherogenic index were significantly decreased and HDL cholesterol level was significantly increased in the children with hypercholesterolemia. Obesity index, triglyceride level and atherogenic index were significantly decreased and HDL cholesterol level was significantly increased in the children with obesity. In addition, the frequencies of the children with dyslipidemia or liver dysfunction were significantly decreased in the obese children after one year. These data suggested that the screening system and the plans after the examinations described here were effective in reducing risk factors for atherosclerosis in children.

During the last twenty years we witnessed a remarkable increase in knowledge of the mechanism as regards insulin action, the central hormone of metabolic regulations. Interest in cellular and molecular mechanisms of action was conditioned by a high prevalence of insulin resistance and the fact that insulin resistance holds a key position in the pathogenesis of many diseases, in particular atherosclerosis, obesity, hypertension, diabetes mellitus type II, ovarian hyperandrogenism and others. The syndrome of hyperinsulinaemia/insulin resistance is the basic component of the so-called X syndrome defined in 1988 by Reaven. It is encountered in subjects with a normal glucose tolerance but a predisposition for diabetes type II. If this disposition, probably genetic by nature, is potentiated by the central type of obesity and a sedentary lifestyle it can influence the development of hypertension and dyslipidemia. The sum of these factors promotes acceleration of atherosclerosis and frequently its premature manifestations: myocardial infarction and other cardiovascular diseases which hold the first place as regards causes of death on a world wide scale. It is important to identify but also to treat this complex not only metabolic risk factors for macrovascular diseases. It is a paradox that some drugs used as antihypertensives can cause deterioration of insulin resistance, subsequently influence in an adverse manner dyslipidemia and thus increase the metabolic risk of cardiovascular diseases. In the submitted paper the authors tried to summarize hitherto expressed views on the syndrome of hyperinsulinaemia and insulin resistance, using as a basic the results of their own work.

Cholesterol-lowering drugs include three major pharmacological classes: a) fibrates, b) statines, HMG-CoA reductase inhibitors and c) cholestyramine. The late eighties were characterized by the introduction of HMG-CoA reductase inhibitors in therapeutics. For 12 months (1st January-31 December 1991), a prospective intensive program of pharmacovigilance investigated the occurrence of side effects among the three pharmacological classes of cholesterol-lowering drugs in a specialized unit for prevention of atherosclerosis and dyslipidemia. Among 3,506 out patients who received cholesterol-lowering drugs, 36 side effects were reported (i.e. 1 side effect for 98 out-patients). Most of the side effects were observed with statines (61%). The most frequently observed side effects were gastralgia (19.5%) observed with the three classes of drugs and hepatitis with HMG-CoA reductase inhibitors (8.5%) or fibrates (3%) whereas myopathy (12%) only occurred with statines. The other side effects were cutaneous (14%: eczema, skin rashes) or neuropsychiatric (11%: insomnia...) ones. This study emphasizes the low frequency of severe side effects (myopathy: 1 per 1,000 prescriptions, hepatitis: 1 per 1,000 prescriptions) with cholesterol-lowering drugs in current practice.

Diabetic patients have a 2 to 4 times higher risk of development of atherosclerosis than non-diabetic subjects. One of the risk factors of atherosclerosis is an impaired lipid and lipoprotein metabolism which is influenced by the type of diabetes, the degree of its metabolic compensation, character of treatment and other concurrently present metabolic abnormalities. In metabolically balanced type 1 diabetes the levels of commonly assessed lipoproteins do not differ from those in non-diabetic subjects, the HDL-cholesterol level can be even higher. The lipid profile of type 2 diabetics is not very homogeneous, however, usually elevated levels of VLDL-triglycerides and of apoprotein B and a reduced HDL-cholesterol level are found. At present there are no unequivocal views on the role of the lipoprotein (a) ratio in the increased risk of atherosclerosis in diabetics as investigations devoted to the lipoprotein (a) level and its relation to macrovascular complications in diabetes did not give unequivocal results. The scope of dyslipidemia in diabetics with nephropathy is in addition to the effect of the basic disease influenced also by the extent of renal damage. The lipid disorder, on the other hand, leads to deterioration of albuminuria and progression of the renal disease.

Insulin resistance has been recently distinguished as a syndrome associated with a clustering of metabolic disorders, including non-insulin dependent diabetes mellitus (NIDDM), obesity, hypertension, dyslipidemia and atherosclerosis. To date, it is thought that all of these disorders are the resulting consequences of primary insulin resistance. We propose that insulin resistance and the metabolic diseases mentioned can be caused by primary overactivity of the Na+/H+ exchange. This hypothesis has practical connotations for understanding the pathogenesis of the insulin resistance syndrome.

Existing evidence suggests that dyslipidemia associated with long-lasting nephrotic syndrome and with chronic renal insufficiency may favor in the long run the occurrence of cardiovascular complications, and also aggravate glomerular damage with a pathological mechanism analogous to atherosclerosis. Correction of hypercholesterolemia and hypertriglyceridemia is therefore mandatory in both clinical conditions. This goal can be achieved with the combination of dietary intervention and the administration, even for long periods of time, of hypolipemic drugs (hydroxymethylglutaryl coenzyme A, HMGCoA, reductase inhibitors, to correct hypercholesterolemia in nephrotic syndrome, and fibric acids, to correct hypertriglyceridemia in uremic and dialyzed patients are the drugs of choice). In end-stage renal failure, the choice of the type of dialysis is also important. The value of extracorporeal LDL cholesterol removal is still to be proven.

The relationship between obesity and prevalence of dyslipidemia is well known. Recent studies affirm that differences in fat distribution can be predictive for differences in the prevalence of metabolic disturbances and cardiovascular disease independently of the BMI, presently the most common index of obesity. In order to verify whether body fat distribution can be associated with a higher risk of atherosclerosis, we have evaluated in a group of obese women the eventual presence of endocrine and metabolic diseases. Assessing regional fat distribution, the waist/hip ratio has been shown to be more closely correlated with these diseases than BMI. We have studied two groups of 10 women, comparable for age and BMI: group A aged 45.8 +/- 6.9 years with a BMI of 35.6 +/- 2.8 kg/m2; group B aged 48.3 +/- 3.6 years with a BMI of 38.5 +/- 2.8 kg/m2. The women were divided according to the waist-hip ratio, which was calculated by measuring the circumference of the waist, namely the smallest circumference between the xiphoid and the umbilicus, and the circumference of the hips at the point of the maximum protuberance of the buttocks. The cut-off value for the waist/hip ratio was considered as 0.80 for the reason that this variable is the most accurate cut-off value for abdominal obesity: for group A 0.76 +/- 0.02; for group B 0.89 +/- 0.02 (p < 0.01). All the women were healthy. None of them was in therapy with any kind of drugs, nor was there any restriction to diet. Nobody was a smoker, neither did anyone drink alcoholic beverages.(ABSTRACT TRUNCATED AT 250 WORDS)

Atherosclerosis is the principal cause of diabetic morbidity and mortality. Diabetic dyslipidemia, obesity, and hypertension are significant contributing factors in the acceleration of the atherosclerotic process. Regardless of the type of diabetes, increased levels of very-low-density lipoprotein triglyceride, modified levels of low-density lipoprotein cholesterol, and decreased levels of high-density lipoprotein (HDL) cholesterol are the main lipoprotein abnormalities in diabetic patients. These abnormalities can be improved in part by glycemic control, but additional intervention may be needed. Diet and exercise are important elements in the management of dyslipidemia, but lipid-lowering drugs (especially fibrates and HMG-CoA reductase inhibitors) also may be necessary for the control of diabetic dyslipidemia. Based on these findings, the American Diabetes Association Consensus Panel and the revised treatment guidelines of the National Cholesterol Education Program recommend treatment of hypertriglyceridemia/low HDL cholesterol as a risk factor of coronary heart disease in diabetic and nondiabetic individuals alike. Aggressive treatment is recommended, therefore, particularly in diabetic patients and in all patients with existing vascular disease.

Peripheral insulin resistance with normal glucose homeostasis and compensatory hyperinsulinemia is a common feature of a series of conditions. It is usually present in obesity and initiates the events leading to non insulin dependent diabetes. It is also pathogenetically related to hypertension, dyslipidemias and clinical atherosclerosis, diseases that are frequently associated between them. Although its etiology remains partially unknown, strong evidences suggest that it is due to a post receptor defect, involving the intracellular signals that drive carbohydrate metabolism. This explains the preservation of other insulin actions and the effect of hyperinsulinemia on hypertension, dyslipidemia and atherogenesis. In obesity, the increased lipid oxidation and serum free fatty acid levels, inhibit enzymes and cofactors involved in carbohydrate metabolism. This leads to a reduction in glucose disposal and increases hepatic glucose output, outlining a post receptor defect leading to insulin resistance.

The effect of bovine lipoprotein lipase (LPL) on very low density lipoprotein (VLDL) binding to subendothelial matrix was studied. Without LPL, VLDL bound poorly to the matrix. However, decreasing NaCl or elevating Ca++ concentration increased matrix VLDL binding. With LPL, VLDL binding was markedly increased. Since LPL is a normal constituent of the artery wall and is elevated in atherosclerotic lesions, we postulate two potential mechanisms for the involvement of VLDL and LPL in atherogenesis. First, VLDL acquisition is attenuated by the increased matrix LPL content in the developing atheroma. Secondly, elevated plasma levels of VLDL (and VLDL remnants) such as in Type II or III dyslipidemia could enhance such interactions. These events likely accelerate the rate of atherosclerosis lesion development.
