Gout is a disease caused by deposits of sodium urate crystals in tissues. This disease, already known of Hippocrates, is now due to new causes, notably iatrogenic, and has new clinical forms. The typical initial attack usually occurs in men in their fifties and affects the big toe; in the absence of treatment it evolves towards chronic tophaceous gout. When gout occurs in subjects younger than 30 years, these must be investigated for enzyme deficit which is usually partial. The incidence of gout in women is ever increasing, being encouraged by treatments with diuretic drugs. Gout is often atypical, affecting predominantly the hands and with rapid development of tophus. In transplanted patients other drugs, such as cyclosporin, may induce an early, polyarticular and tophaceous gout. Alcohol is a facilitating factor of hyperuricaemia. Disturbances of metabolism, such as hyperlipidaemia, obesity or arterial hypertension, are often associated with hyperuricaemia. With an early and well-conducted treatment the passage to chronicity and the occurrence of complications can be avoided.

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.

In obese adults body fat distribution is more closely associated with cardiovascular risk factors and cardiovascular disease, type II diabetes and gout than the degree of obesity; the android, abdominal body fat pattern carrying more risk than the gynoid, femoral form. For characterizing the different types of fat distribution the ratio of waist to hip girth (WHR) is commonly used. The question was whether these facts can already be demonstrated in obese children. In the studied group of 69 obese children, aged between 3-16 years (mean = 10.8 years) with a mean of 47% overweight no correlations between percentage overweight and waist hip ratio could be found. Better correlations of serum triglycerides, total- and LDL-cholesterol, the atherogenic index LDL/HDL-cholesterol, fasting insulin level, oral glucose tolerance and blood pressure were obtained with percentage overweight than with waist-hip-ratio. HDL-cholesterol was the only parameter showing better and significant correlation with waist-hip-ratio than with percentage overweight. These results are in contrast to the situation in adults but are comparable with other studies in normal weighed and obese children, where correlations of waist hip ratio with body fat and risk factors were low in childhood, becoming higher in adolescence. Only after onset of puberty does waist hip ratio seem to be an indicator for body fat distribution and for possibly associated additional risk factors as in adults. For estimation of the cardiovascular risk in obese children, determination of WHR need not to be recommended.(ABSTRACT TRUNCATED AT 250 WORDS)

We now have sufficient knowledge to be able to identify the factors contributing to hyperuricemia in most patients with gout. Some of these factors, such as obesity, a high-purine diet, regular alcohol consumption, and diuretic therapy, may be correctable. In patients with persistent hyperuricemia, regular medication should lower the serum urate concentration to an optimal level. The continuing challenge is to educate patients about correctable factors and the importance of regular medication and ensure their compliance so that attacks of gout do not recur.

Choice of diet is one way in which an individual can influence his/her own health, and it is to be expected that patients will seek their physician's expert opinion regarding dietary matters. Respect for the legitimacy of these enquiries and balanced informed discussion, which includes general advice for a prudent diet, as well as disease-specific recommendations when indicated, can be the key to a productive relationship between patients and physician. The issue of dietary advice has an impact on the management of most forms of arthritis including osteoarthritis (obesity/energy balance), gout (dietary purines, energy balance, alcohol, fluid intake) and rheumatoid arthritis (n-3 fatty acids). Food hypersensitivity appears to be a rare cause of polyarthritis, and elimination diets and fasting have little or no place in routine practice. Strategies under investigation include oral tolerization, the utility of which remains to be established.

Experts agree that overweight and obesity pose a significant public health problem in the United States. Obesity is considered to be a complex, multifactorial disease involving genetics, physiology, psychology, and environment, and is influenced by cultural messages. Comorbidities linked to obesity include coronary heart disease, stroke, hypertension, diabetes mellitus, gout, dyslipidemias, cholecystitis, and gallstones. Pharmacists can help patients with dietary goals by understanding sound principles of weight management.

Characteristic feature of pathogenesis, epidemiology and laboratory findings in hyperuricemia of gouty patients are studied and reasonable treatments of gout in clinical medicine are discussed. Gout is characterized by repeated arthritis attacks on the metacarpophalangeal joint of the first toe or other small joints, especially overworked joints or those exposed to cold. The arthritis attack lasts for 3.5 days and then diminishes gradually. The intervals are shortened in patients under poor hyperuricemic control but tophi formation is less frequent. Complications in combination with hyperlipidemia, diabetes mellitus, obesity and hypertension, which are compatible to syndrome X, are frequent in gouty patients and are suspected of rapidly progressing to arteriosclerosis, such as ischemic heart diseases. Hyperuricemia consists of over-production and underexcretion, which can be diagnosed by the urate clearance test. Classification is valuable for surveying the underlying diseases of secondary hyperuricemia and treating gouty patients. Underexcretion was observed in 85% of gouty patients with hyperuricemia and even the mean urate clearance in the overproduction type was significantly lower than that of normal controls, suggesting that underexcretion is a fundamental phenomenon in all gouty patients. Treatments of complications as well as those of hyperuricemia with uricosuric agents are required for clinical treatment of gouty patients.

Several health hazards and social disabilities are associated with obesity. Increased mortality is associated with increased body weight. A high rate of mortality results from heart disease, diabetes mellitus, gallbladder disease, high blood pressure, and cancer. Physiologic cardiovascular changes occur, leading to left ventricular hypertrophy and lipid abnormalities. Hypertension, stroke, and venous stasis are increased. Pulmonary abnormalities include obstructive sleep apnea, which can be associated with secondary polycythemia and right ventricular hypertrophy. Gallstones, gallbladder disease, and accumulation of fat on the liver are significantly increased. Gout and reproductive abnormalities in women are common. Osteoarthritis of the knees and spine occur, although osteoporosis is rare. Risk for endometrial and breast cancer is increased, particularly in the presence of increased central fat. Changes in the skin include stretch marks, acanthosis negricans, hirsutism, intertrigo, and multiple papillomas. Impaired psychosocial function is manifested as social isolation, loss of job mobility, increased employee absenteeism, and economic and social discrimination.

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.
