The objective of the study was to determine if male subjects with coronary atherosclerotic heart disease (CHD) without major CHD risk factors have hyperinsulinemia and related metabolic changes. Previous studies suggested that hyperinsulinemia is a CHD risk factor, but they did not entirely exclude concurrent metabolic abnormalities. A prospective, comparative, cross-sectional study in a tertiary care teaching hospital in Mexico City was conducted in 15 men who had suffered myocardial infarction 6 to 24 months before and had significant coronary occlusion on angiography. Control group was formed by 15 age-matched healthy men. None had hypertension, obesity, diabetes, gout, glucose intolerance or hyperlipidemia. Body mass index (BMI), waist/hip ratio (WHR), blood pressure (BP); oral glucose tolerance test (OGTT) with measurement of serum glucose, insulin and C-peptide every 30 min for 2 h, fasting serum cholesterol, triglycerides and uric acid, areas under curve (AUC) of glucose and insulin, insulin/glucose ratio and insulin sensitivity index were calculated. BMI, WHR and BP were similar in both groups. Fasting and post-load serum glucose and insulin concentrations were significantly higher in CHD than in control group (p < 0.01); fasting glucose 5.9 +/- 0.6 vs. 4.8 +/- 0.7 nmol/1, 2-h glucose 8.3 +/- 0.6 vs. 7.3 +/- 0.9 mmol/l, fasting insulin 17.5 +/- 1.2 vs. 15.3 +/- 1.7 pmol/l, 2 h insulin 448 +/- 108 vs. 282 +/- 87 pmol/l in CHD and control group, respectively. AUC of glucose, AUC of insulin, insulin/glucose ratio, post load C-peptide, serum cholesterol, triglycerides and uric acid levels were also significantly higher in CHD than in healthy controls. Insulin sensitivity index was significantly lower in patients with CHD (27.7 +/- 8.3) than in healthy control subjects (73.9 +/- 18) (p < 0.001). Patients with CHD have hyperinsulinemia and subtle metabolic abnormalities related with insulin resistance even in absence of overt risk factors.

The purpose of this study was to determine the characteristics of gouty arthritis in an urban Guatemalan population. We reviewed the medical records of 148 (145 males and 3 females) patients with a diagnosis of acute gouty attack seen at an urban rheumatology clinic in Guatemala City between 1982 and 1993. Mean age at diagnosis was 49 years (range 21-87), mean age of onset was 42 years, mean duration of disease 7.4 years, family history of gout 42 (28%), peak prevalence 5th decade 39 (26%). Seventy-one (48%) had monarticular, 49 (33%) oligoarticular, and 22 (15%) polyarticular attacks, respectively. Podagra was seen in 34 (23%) patients; however, 108 (73%) developed it at any moment of their life. Tophaceous gout was seen in 33 (22%). Mean serum urate concentrations (enzymatic method) were higher than 7.0 mg % in 90 (60%) patients. At follow-up, 44 (30%) patients never returned to our clinic, and a large majority of them [66 (45%)] were seen only during acute attacks. Associated disorders included hypertension (43%), obesity (27%), nephrolithiasis (16%), ischaemic heart disease (7%), renal insufficiency (2%), stroke (0.6%), and diabetes mellitus (0.6%), and two died due to sepsis; high alcoholic intake was found in 58 (39%) patients. In conclusion, our findings indicate that gout is not an unusual disorder in the Guatemalan population. It presents with the same characteristics as those reported in Caucasians, with the possible exception of a lower frequency of diabetes mellitus as an associated disorder.

We evaluated the effect of accumulation of intraabdominal visceral fat on the metabolism of uric acid in 50 healthy male subjects to elucidate any relationship between such obesity and hyperuricemia. The area of abdominal fat (visceral fat and subcutaneous fat) was measured at the level of the umbilicus by abdominal computed tomographic scanning. Serum and urinary concentrations of uric acid and creatinine were determined with an autoanalyzer. Uric acid clearance and the ratio of urinary uric acid to creatinine excreted in urine were calculated. Univariate and multivariate analyses were used to evaluate the relationship between uric acid metabolism and body fat. The size of the area of visceral fat was significantly correlated with the serum concentration of uric acid (r = .37, P < .01), uric acid clearance (r = -.34, P < .05), and the urinary uric acid to creatinine ratio (r = .65, P < .0001). The size of the area of subcutaneous fat was significantly correlated only with the urinary uric acid to creatinine ratio (r = .38, P < .01). Multivariate analyses, including body mass index (BMI), showed that the size of the visceral fat area was the strongest contributor to an elevated serum concentration of uric acid, a decrease in uric acid clearance, and an increase in the urinary uric acid to creatinine ratio. These results suggest that accumulation of visceral fat may have a greater adverse effect on the metabolism of uric acid than BMI or accumulation of subcutaneous fat. Clearly, patients with hyperuricemia should lose weight to reduce excessive visceral fat stores, to help avoid attacks of gout.

An increasing prevalence of obesity all over the world reflects a lack of effective measures in both prevention and treatment of obesity. Obesity as a disease has been underestimated by the lay-public as well as health care providers. However, obesity represents a substantial health problem associated with a decreased quality of life. Obesity is linked to numerous chronic diseases (cardiovascular diseases, diabetes, hyperlipidemia, gout, osteoarthritis, gall-stones, and bowel, breast and genitourinary cancers) that lead to premature disability and mortality. Health risks increase with a body mass index (BMI) over 25 in individuals 19-35 years of age and with a BMI over 27 in those 35 years of age and older. Health risks also increase with an excess accumulation of visceral fat manifested as an increase in waist circumference (> 100 cm) or in waist to hip ratio (> 0.85 for females and > 1.00 for males). According to studies carried out in different countries current economic costs of obesity represent 5-8% of all direct health costs. In contrast, effective treatment of obesity results in a substantial decrease in expenditures associated with pharmacotherapy of hypertension, diabetes, hyperlipidemia and osteoarthritis. Both scientists and clinicians involved in obesity research and treatment recommend to introduce the long-term weight management programs focussing more on the overall health of the participants than the weight loss per se. Therefore, it will be necessary to establish new realistic goals in the obesity management that reflect reasonable weights and recently experienced beneficial health effects of modest (5-10%) weight loss. Comprehensive obesity treatment consisting of low fat diet, exercise, behavioral modification, drug therapy and surgical procedures requires differentiated weight management programs modified according to the degree and type of obesity as well as to current health complications present. The Czech Society for the Study of Obesity defined a comprehensive weight reduction program carried out in weight reduction clubs, out-patient obesity clinics and in specialized departments attached to the university hospitals. In order to provide an integrated knowledge from many different disciplines connected with obesity three week postgraduate course has been organized for physicians involved in obesity management. Even the most spread weight reduction clubs in our country (STOB) are supervised by the trained counselors. The main goal of different weight management programs is to find out optimal approaches leading to long-term beneficial outcome and ameliorating the variety of disorders associated with obesity.

The clinical features of 90 Black South African patients with gout seen at a large urban hospital were reviewed. The mean age of the patients was 54.3 and 55.3 years for men and women, respectively. The male:female ratio was 3.3:1. All except one of the women were postmenopausal. Seventy-nine percent of patients were from the lower income groups of "blue collar" workers, old-age pensioners or the unemployed. Polyarticular gout was observed in 44.4% of the patients. Tophi were noted in 51.1% of patients but none had a history of renal calculi. Risk factors were assessed by comparing the gouty patients to an equal number of age- and sex-matched hospital controls. Case-control analysis showed a "white collar" occupation (odds ratio = 7.4), obesity (odds ratio = 5.3), alcohol intake (odds ratio = 3.5) and hypertension (odds ratio = 3.3) to be significant risk factors for gout in the overall group of both men and women. In the subgroup of men only, obesity (odds ratio = 7.8), a "white collar" occupation (odds ratio = 6.4), hypertension (odds ratio = 4.9) and alcohol intake (odds ratio = 3.5) were similarly associated with gout. In women, a history of alcohol intake was the only significant risk factor associated with gout (odds ratio = 5.0). These findings suggest that in a population where gout was previously rare, changing dietary habits and lifestyle, together with improving socioeconomic conditions are contributing significantly to the increasing prevalence of the disease.

An epidemiologic study to determine lipids and biochemical traits was performed in central Taiwan aborigines with and without gout and in the local Han Chinese. The lipid profile included measurement of serum triglyceride, cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A-I (apoA-I), and apoB. The results showed no significant difference for body mass index (BMI) and cholesterol between the three groups. Greater alcohol consumption was found in aborigines with gout compared with the other two groups. With univariate analysis, serum triglyceride, uric acid, creatinine, LDL-C, and apoB were significantly higher in aborigines with gout versus aborigines without gout or Han people (P<.001). By contrast, HDL-C and apoA-I were significantly lower in aborigines with gout (P<.001 or .01). However, with multivariate analysis, only serum triglyceride, uric acid, and apoB-1 were significantly different between aborigines with versus without gout. In conclusion, the apparent lipid abnormalities, particularly triglyceride and apoB, in Taiwan aborigines with gout are unlikely secondary to obesity. Instead, excessive alcohol intake or genetic factors may play a role in inducing hyperlipidemia in gout.

Gout is a disease resulting from the deposition of urate crystals caused by the overproduction or underexcretion of uric acid. The disease is often, but not always, associated with elevated serum uric acid levels. Clinical manifestations include acute and chronic arthritis, tophi, interstitial renal disease and uric acid nephrolithiasis. The diagnosis is based on the identification of uric acid crystals in joints, tissues or body fluids. Treatment goals include termination of the acute attack, prevention of recurrent attacks and prevention of complications associated with the deposition of urate crystals in tissues. Pharmacologic management remains the mainstay of treatment. Acute attacks may be terminated with the use of nonsteroidal anti-inflammatory agents, colchicine or intra-articular injections of corticosteroids. Probenecid, sulfinpyrazone and allopurinol can be used to prevent recurrent attacks. Obesity, alcohol intake and certain foods and medications can contribute to hyperuricemia. These potentially exacerbating factors should be identified and modified.

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.

Influence of dietary habits, body weight on blood uric acid was studied in 416 elderly people. The result showed that level of blood uric acid in the people who had habits of drinking alcohol, tea and taking hot foods was higher than that who never had those habits (P < 0.05 or 0.01). It also showed that level of blood uric acid was significantly increased in the over-weight or obesity people (P < 0.05). The hyperuricemia incidence in the over-weight or obesity people is 27.4 per cent, and it is 2 times and 3.4 times of the people with ideal weight and weak-weight, respectively. It is suggested that the patients with gout or hyperuricemia give up drinking alcohol, tea and taking hot foods for their health. Reducing body weight is one of the effective measures to prevent and treat gout or hyperuricemia in the elderly.

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).
