The Authors have analyzed the complex problems of the possible binding between uric acid and plasma proteins using two methods consisting of serum ultrafiltration at 22 degrees C or electrophoresis on different supports with successive specific coloration of the free and bound uric acid. The percentage of free and bound uric acid was established in serum from normal subjects, patients with primary gout, patients with renal insufficiency treated by dialysis and subjects with type IV dyslipidemia. The Authors discuss the results obtained as regards the possible role played by urate-plasma proteins binding in the interpretation of a genetic defect present in gouty patients involving a diminished uric acid binding capacity of plasma proteins.

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.

Dyslipidaemia may be treated with a number of safe and effective pharmacological agents that target specific lipid disorders through a variety of mechanisms. The bile-acid sequestrants--cholestyramine and colestipol--primarily decrease LDL cholesterol by binding bile acids, thereby decreasing intrahepatic cholesterol, and by increasing the activity of LDL receptors. Nicotinic acid lowers LDL cholesterol and triglyceride by decreasing VLDL synthesis and by decreasing free fatty acid mobilization from peripheral adipocytes. The HMG-CoA reductase inhibitors--fluvastatin, lovastatin, pravastatin and simvastatin--lower LDL cholesterol by partially inhibiting HMG-CoA reductase (the rate-limiting enzyme of cholesterol biosynthesis) and by increasing the activity of LDL receptors. The fibric-acid derivatives--bezafibrate, ciprofibrate, clofibrate, fenofibrate and gemfibrozil--primarily decrease triglyceride by increasing lipoprotein lipase activity and by decreasing the release of free fatty acids from peripheral adipose tissue. Probucol decreases LDL cholesterol by increasing non-receptor-mediated LDL clearance; as an anti-oxidant, probucol also decreases LDL oxidation; oxidized LDL which is thought to lead to atherogenesis. Although these agents have been proven safe in clinical trials, like any drug, they carry the risk for adverse effects. The bile-acid sequestrants may cause constipation, reflux oesophagitis, and dyspepsia, and may bind coadministered medications such as digitalis glycosides, beta blockers, warfarin, and exogenous thyroid hormone. Nicotinic acid use is commonly associated with flushing and pruritus and may also cause non-specific gastrointestinal complaints, hepatotoxicity (hepatic necrosis, hepatitis, or elevated liver enzymes), gout, myolysis, decreased glucose tolerance and increased fasting glucose levels, and ophthalmological complications including decreased visual acuity, toxic amblyopia, and cystic maculopathy. The HMG-CoA reductase inhibitors may produce liver enzyme elevations, creatine kinase elevations and rhabdomyolysis. The combination of a reductase inhibitor and a fibrate increases the risk for rhabdomyolysis. Possible adverse effects of the fibric-acid derivatives include abdominal discomfort, nausea, flatulence, increased lithogenicity of bile, liver enzyme elevations and creatine kinase elevations. Probucol may increase the QTc interval and may cause non-specific gastrointestinal complaints.

Niacin has been used for many years to treat hyperlipidemia. It has been shown to reduce coronary death and non-fatal myocardial infarction and, in a separate analysis of long-term (15-year) follow-up, all cause mortality. It reduces total cholesterol, low density lipoprotein cholesterol (LDL-C) and triglycerides and increases high density lipoprotein cholesterol (HDL-C). Sustained-release niacin may be associated with more dramatic changes in LDL-C and triglyceride, whereas the short acting preparation causes greater increases in HDL-C. The increase of HDL-C occurs at a lower dose (1500 mg/day) than the reduction of LDL-C (> 1500 mg/day). Niacin also favorably influences other lipid parameters including lipoprotein(a) [Lp(a)], alimentary lipemia, familial defective apolipoprotein B-100 and small dense LDL. Combination of niacin with a bile acid sequestrant or a reductase inhibitor represents a powerful lipid-altering regimen. Whereas the reductase inhibitors and bile acid binding resins primarily affect LDL-C, the combined therapy has a synergistic effect to reduce LDL-C and, in addition, the niacin reduces triglycerides and increases HDL-C. The major drawback in the use of niacin is associated side effects (flushing and palpitations) and toxicity (worsening of diabetes control, exacerbation of peptic ulcer disease, gout, hepatitis). Niacin has a long history of use as a lipid lowering agent and has several attractive features. Unfortunately, the side effect profile of this agent warrants its use only in patients with marked dyslipidemia in whom side effects and potential toxicity are closely monitored.

Obesity leads to and exacerbates many serious disorders, including hypertension, dyslipidemia, cardiovascular disease, non-insulin-dependent diabetes mellitus, gallbladder disease, respiratory dysfunction, gout, and osteoarthritis. Many short-term studies have shown that weight loss can ameliorate or, in some cases, reverse such disorders. Fewer long-term studies-defined as those whose combined acute intervention and follow-up phases extend for at least 1 year-of the therapeutic benefits of weight loss on specific disorders have been undertaken. Those long-term studies that have been performed tend to confirm the results of briefer studies. Even when weight loss has been comparatively modest or some degree of weight regain has occurred, weight loss is generally associated with a decrease in risk factors and the alleviation of clinical symptoms.

Overweight and obese adults are at increased risk for morbidity and mortality associated with many acute and chronic medical conditions, including hypertension, dyslipidemia, coronary heart disease, diabetes mellitus, gallbladder disease, respiratory disease, some types of cancer, gout, and arthritis. In addition, overweight during childhood and adolescence is associated with overweight during adulthood, and previous reports have documented an increase in the prevalence of overweight among children, adolescents, and adults from 1976-1980 to 1988-1991. This report presents data from CDC's Third National Health and Nutrition Examination Survey (NHANES III) (1988-1994) to provide the most recent national estimates of overweight among children (ages 6-11 years), adolescents (aged 12-17 years), and adults (aged > or = 20 years) in the United States. The findings indicate that the prevalence of overweight in the United States has continued to increase.

Aim of this paper is to describe and discuss, on the basis of the available current literature, the case of a female patient affected by a tophaceous gout associated with plurimetabolic syndrome. Hyperuricemia and gout may be seen today in all the populations of developed countries, with increasing frequency on the last fifty years. Increased production or reduced urinary excretion of uric acid (and hypoxanthine and xanthine) are the most important pathogenetic mechanisms of primary or secondary hyperuricemia. Gout is an acute rheumatic disorder (characterized by a limited range of manifestations) which occurs in humans in connection with deposition of crystals of monosodium urate (the final product of purine metabolism) in the articular and soft periarticular tissues. Hyperuricemia and/or gout are often associated with hyperinsulinemia, obesity, diabetes mellitus, hyperlipemia, hypertension and atherosclerosis to form the syndrome called "Plurimetabolic syndrome" or "Syndrome X". Here we report the clinical case of a 64-year-old female patient who had android obesity, type 2 diabetes mellitus, hypertension, dyslipidemia and hyperuricemia and had been suffering (over many years) from intermittent episodes of severe pain and inflammatory joint swelling (first metacarpo- and metatarso-phalangeal joints) with development of pronounced multiple tophi in bone articular and soft periarticular tissues. Hyperuricemia and acute episodes had never been treated with anti-hyperuricemic drugs because gouty arthritis had never been diagnosed. This severe tophaceous gout associated to multiple metabolic disorders prompted us to present knowledge on gout and to focus on the interrelationships between hyperuricemia and/or gout and plurimetabolic syndrome, important risk factors for coronary heart disease.

Obese patients are at an increased risk for developing many medical problems, including insulin resistance and type 2 diabetes mellitus, hypertension, dyslipidemia, cardiovascular disease, stroke, sleep apnea, gallbladder disease, hyperuricemia and gout, and osteoarthritis. Certain cancers are also associated with obesity, including colorectal and prostate cancer in men and endometrial, breast, and gallbladder cancer in women (1-6). Excess body weight is also associated with substantial increases in mortality from all causes, in particular, cardiovascular disease. More than 5% of the national health expenditure in the United States is directed at medical costs associated with obesity (7). In addition, certain psychologic problems, including binge-eating disorder and depression, are more common among obese persons than they are in the general population (8.9). Finally, obese individuals may suffer from social stigmatization and discrimination, and severely obese people may experience greater risk of impaired psychosocial and physical functioning, causing a negative impact on their quality of life (10).

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.
