The diagnostics of hyperlipoproteinaemias is essentially based on the proof of biochemical parameters. The simultaneous determination of triglycerides and cholesterol in the serum is the most important measure for establishing disturbances of the lipid metabolism. The behaviour of these two lipids, the consideration of the serum and the lipoprotein electrophoresis in most cases make possible a classification according to the distributed all over the world and clinically relevant division according to Fredrickson. Loading tests for the early recognition of hyperlipoproteinaemias - analogus to protodiabetes - are hitherto not yet known. Within the diagnostics shoude be taken into consideration that hyperliproproteinaemias are frequently associated with other metabolic diseases (obesity, gout, diabetes mellitus, hypertension) as so-called metabolic syndrome.

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 metabolic syndrome usually goes along with abdominal obesity: diabetes type II, hypertension, dyslipidemia, and gout are often associated. The common characteristic is the resistance to insulin action. Reasons for the metabolic syndrome are--besides a genetic determination--overnutrition, physical inactivity, and alcohol consumption. Therefore, a causal therapy aims at the elimination of these factors. Consequently, the non-pharmacological therapy of the metabolic syndrome should be emphasized. The most important treatment is the reduction of body weight in the presence of obesity which is relevant for almost 90% of the patients. Body weight can rapidly be diminished by hypocaloric diets. Both, conventional reducing diets or formula diets may be used for weight reduction. Total fasting should not be performed for several reasons. For minor weight reduction or weight maintenance following a period of rapid weight loss with a hypocaloric diet, increased physical activity also lowers weight or prevents relapsing. Aims of therapeutical procedures are the elimination or amelioration of insulin resistance and subsequently the diseases of the metabolic syndrome. Both methods, reducing diet and physical training, act on various factors related to insulin resistance. For example, hypocaloric diets activate thyroxine kinase of the insulin receptor and reduce glucose and insulin in plasma. Physical training reduces not only insulin and glucose in plasma but also free fatty acids in addition and increases capillary density in skeletal muscle. Using the glucose clamp technique, diets and training are equally effective in improving glucose metabolism. Compared to these non-pharmacological methods drugs are less convincing. Since the non-pharmacological treatment implies behavioral changes with regard to nutrition, physical activity and alcohol consumption, simple instructions are not sufficient. Usually long-lasting changes in life style are necessary in order to achieve health improvement. Therefore, health care programs on individual or social basis are required in order to improve nutrition and increase physical activity. However, long-acting effects are difficult to achieve in adults; more promising is the prevention of insulin resistance.

The associates of gout-obesity, hypertriglyceridemia, glucose intolerance, and hypertension, strikingly resemble those of insulin resistance. In the present study we determined whether hyperuricemia is associated with insulin resistance and, if so, whether this association can be explained by other components of the syndrome. For this purpose we quantitated insulin sensitivity (euglycemic clamp) in 37 nondiabetic subjects (aged 30-68 yr) exhibiting varying degrees of the metabolic syndrome (body mass index, 21.5-35.7 kg/m2; serum triglycerides, 0.4-22.0 mmol/L; high density lipoprotein cholesterol 0.38-1.86 mmol/L; blood pressure, 190-100/116-60 mm Hg). In simple linear regression analysis, the serum uric acid concentration (range, 182-568 mumol/L) was inversely correlated with insulin sensitivity (rate of glucose utilization; r = -0.61; P < 0.001) and positively with serum triglycerides (r = 0.68; P < 0.001), but not with body mass index, age, or the plasma glucose concentration. In multiple linear regression analysis, both insulin sensitivity (P < 0.05) and serum triglycerides (P < 0.005) were independently associated with the serum uric acid concentration, and together explained 50% of its variation. Addition of body mass index or age to the model did not improve the degree of explanation. Acute elevation of serum triglycerides about 3-fold, of plasma FFA about 9-fold, or of serum insulin about 28-fold had no effect on the serum uric acid concentration in healthy volunteers. The data indicate that hyperuricemia is indeed an inherent component of the metabolic syndrome and could also be used as a simple marker of insulin resistance.

Therapy of hyperuricemia and gout has to depend on pathogenesis and stage of the disease. Dietary regimen are in the forefront in treatment of asymptomatic hyperuricemia. Uric acid lowering drugs can only be supported in repeated serum-measures from 9 mg/dl up. The therapy of an acute attack of gout primarily is done with non-steroidal antiinflammatory drugs, in rare cases with colchicine or corticoids. Gouty arthritis in intermission, independent of the extent of hyperuricemia, as well as chronic gout are indications for an uric acid lowering pharmacotherapy, usually for life. A special therapeutic challenge arises out of renal complications and the frequent association with the metabolic syndrome.

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.

The prevalence of the metabolic syndrome is increasing owing to lifestyle changes leading to obesity. This syndrome is a complex association of several interrelated abnormalities that increase the risk for cardiovascular disease and progression to diabetes mellitus (DM). Insulin resistance is the key factor for the clustering of risk factors characterizing the metabolic syndrome. The National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III defined the criteria for the diagnosis of the metabolic syndrome and established the basic principles for its management. According to these guidelines, treatment involves the improvement of the underlying insulin resistance through lifestyle modification (eg, weight reduction and increased physical activity) and possibly by drugs. The coexistent risk factors (mainly dyslipidemia and hypertension) should also be addressed. Since the main goal of lipid-lowering treatment is to achieve the NCEP low-density lipoprotein cholesterol (LDL-C) target, statins are a good option. However, fibrates (as monotherapy or in combination with statins) are useful for the treatment of the metabolic syndrome that is commonly associated with hypertriglyceridemia and decreased high-density lipoprotein cholesterol (HDL-C) levels. The blood pressure target is < 140/90 mm Hg. The effect on carbohydrate homeostasis should possibly be taken into account in selecting an antihypertensive drug. Patients with the metabolic syndrome commonly have other less well-defined metabolic abnormalities (eg, hyperuricemia and raised C-reactive protein levels) that may also be associated with an increased cardiovascular risk. It seems appropriate to manage these abnormalities. Drugs that beneficially affect carbohydrate metabolism and delay or even prevent the onset of DM (eg, thiazolidinediones or acarbose) could be useful in patients with the metabolic syndrome. Furthermore, among the more speculative benefits of treatment are improved liver function in nonalcoholic fatty liver disease and a reduction in the risk of acute gout.

Hypertension and hypertension-associated ESRD are epidemic in society. The mechanisms responsible for renal progression in mild to moderate hypertension and those groups most at risk need to be identified. Historic, epidemiologic, clinical, and experimental studies on the pathogenesis of hypertension and hypertension-associated renal disease are reviewed and an overview/hypothesis for the mechanisms involved in renal progression is presented. There is increasing evidence that hypertension may exist in one of two forms/stages. The first stage, most commonly observed in early or borderline hypertension, is characterized by salt-resistance, normal or only slightly decreased GFR, relatively normal or mild renal arteriolosclerosis, and normal renal autoregulation. This group is at minimal risk for renal progression. The second stage, characterized by salt-sensitivity, renal arteriolar disease, and blunted renal autoregulation, defines a group at highest risk for the development of microalbuminuria, albuminuria, and progressive renal disease. This second stage is more likely to be observed in blacks, in subjects with gout or hyperuricemia, with low level lead intoxication, or with severe obesity/metabolic syndrome. The two major mechanistic pathways for causing impaired autoregulation at mild to moderate elevations in BP appear to be hyperuricemia and/or low nephron number. Understanding the pathogenetic pathways mediating renal progression in hypertensive subjects should help identify those subjects at highest risk and may provide insights into new therapeutic maneuvers to slow or prevent progression.

Gout is an increasingly common medical problem. The traditional risk factors of male sex and high red meat or alcohol consumption have been joined by a wave of newer risk factors, such as increased longevity, the metabolic syndrome (hypertension, diabetes, dyslipidemia, truncal obesity, increased cardiovascular disease risk), use of diuretics, low-dose aspirin, or cyclosporine, and end-stage renal disease. Atypical presentations of gout in the elderly can mimic osteoarthritis and rheumatoid arthritis. There is a resurgence of interest in hyperuricemia as an independent and potentially modifiable cardiovascular risk factor. The pharmacologic management of gout in general practice suffers from a number of quality-control issues. This article reviews these and other new epidemiologic data on this ancient disease.

It has been suggested that hyperuricemia and possibly gout are associated with the metabolic syndrome, but there have been no direct studies. This study was undertaken to obtain the prevalence of the metabolic syndrome in patients with gout and to compare it with those from the general population studies. This was a 4-institutional case-historical control study composed of 168 patients with gout. We assessed the prevalence of metabolic syndrome according to the ATP III criteria and compared the prevalence with that of the historical controls. To elucidate the factors in gout that were associated with metabolic syndrome, a multivariate analysis was done. The age-adjusted prevalence of metabolic syndrome in gout patients was 43.6%, which was significantly higher than that of the Korean control population (5.2%) from the previous studies. Patients with gout had more components of metabolic syndrome than did the controls. Body mass index (BMI, OR = 1.357 (95%CI 1.111-1.657)) and high density lipoprotein (HDL, OR = 0.774 (95%CI 0.705-0.850)) were the variables most significantly associated with the occurrence of metabolic syndrome in gout, but alcohol consumption did not show such associations. Gout is associated with the metabolic syndrome, and furthermore, obesity and dyslipidemia were the factors most associated with the syndrome in these patients.
