Thirty patients with gouty arthritis were studied over 3 years. The diagnosis was established with the help of polarised light microscopy. All the patients were males, with a median age of 45 years. They belonged to the middle or upper socio-economic class and were obese (mean body mass index 29.7). Chronic alcoholism, diabetes mellitus and hypertension were present in one patient each. No patient had symptomatic coronary artery disease. Although 6 patients had a history of renal colic, only one had gouty nephropathy with chronic renal failure. Six patients had a positive family history of gout. The disease involved mostly the joints of the lower extremity and podagra was observed in 70% of patients. Eight patients had tophi at various sites. There were 17 'over producers' and 13 'under excretors' of uric acid. The treatment consisted of patient education, symptomatic control with non steroidal anti-inflammatory drugs and/or colchicine and antihyperuricaemic therapy. The overproducers were treated with allopurinol while the under excretors were treated with [corrected] sulfinpyrazone. In general, there was a good response to therapy as indicated by lowering of serum uric acid and the number of painful episodes per year. The overall profile of the disease appears similar to that seen in the West.

Metabolic diseases with a mass incidence (simple obesity, arterial hypertension, hyperlipoproteinaemia, type II diabetes and gout) are the main risk factors for the manifestation of cardiovascular diseases which can be influenced, as has been reliably proved. They are at present the cause of 56% of all deaths in Czechoslovakia. It is important to emphasize that we are living and dying in an epidemic of cardiovascular diseases. The founder of morbid anatomy, Rudolf Virchow, stated more than 100 years ago: "If the prevalence of a certain disease in a population becomes epidemic, it reflects always a disorder of human culture". It is a fact that a great proportion of the population in Czechoslovakia has adopted during the past decades and still practices an unsound dietary regime and there are other negative lifestyle factors (obesity, smoking, little exercise, high alcohol consumption) for which we pay at present by a declining life expectancy, unnecessary human suffering and the nation as a whole by immense economic losses. The question arises: who and what prevents us from starting in Czechoslovakia as rapidly as possible expedient, comprehensively conceived prevention on a wide front, making use of all findings and advances of world science in this field?

The Japanese population in Hawaii has one of the longest life expectancies of any large population subgroup in the U.S. and the world. Cross-sectional data on 1,379 elderly, noninstitutionalized, male Japanese American survivors of a population-based cohort study indicated the most common health problems were hypertension (43%), arthritis (33%), diabetes (13%), and gout (9%). For cancer and hypertension there is a trend toward higher prevalence in older age groups. For coronary heart disease, stroke, and angina the oldest age group (75-81 years) has a higher prevalence than that seen in younger age groups. Other relatively common diseases such as diabetes, gout, peptic ulcer, and arthritis do not have higher prevalence in older age groups. Drugs reported to be used frequently by study participants were for hypertension, gout, CHD, and diabetes. The prevalence rates of major limitations of mobility and of living alone appear to be relatively low in this population. Less than one percent of the current population rate their health status as poor. The prevalence of normal serum cholesterol and smoking are similar to those seen in U.S. White males, while the rates of hypertension appear lower. Prevalence rates for stroke and heart attack also appear to be somewhat lower in these long-lived individuals than those seen in U.S. Whites.

48 patients, 40 men (mean age 57.4 years) and 8 women (mean age 56.7 years) with stable arterial pressure--II B and III stage according to A. L. Miasnikov's classification, were treated and followed up dynamically in the course of 8 years. The treatment with diuretics, beta-blockers and reserpin has led to a permanent and satisfactory regulation of arterial pressure in most of the patients. Only in 10.4% of the patients the therapeutic results were not satisfactory. In spite of the normalization of the arterial pressure the number of patients with various forms of ischemic heart disease is high--79.2%. The risk factors and their combinations play an important role for this condition (diabetes mellitus, gout, obesity, lipid metabolism changes, etc.). These data imply a new assessment of the drugs used in the treatment of arterial hypertension.

During a prospective cohort-study of several year's duration the results of a survey regarding prevalence of arterial occlusive disease, as well as classical risk factors and rheological profile of patients suffering from vascular disease were examined. 364 patients out of a total of 2,498 individuals suffered from vascular disease. 168 (6.7%) had cardiovascular, 151 (6.0%) cerebrovascular and 109 (4.4%) peripheral vascular disease. Compared to to healthy individuals, the patients showed a significant accumulation of classical risk factors (elevated cholesterol and triglyceride values, decreased HDL-cholesterol concentration, obesity, smoking, high blood pressure, gout or diabetes mellitus). Only 30.2% of the healthy controls presented two or more risk factors, whereas the angiological patients showed two or more risk factors in 71.9%. Rheological parameters measured in the survey were: Plasma viscosity, erythrocyte and platelet aggregation, erythrocyte rigidity and hematocrit. Only 14.2% of the healthy individuals had two or more rheological parameters exceeding the 1-s range, whereas 56.6% of the patients showed two or more elevated rheological parameters.

The drug treatment of mild hypertension has been shown to afford protection against fatal and nonfatal strokes, congestive heart failure, progression to more severe levels of hypertension, and all-cause mortality, but not against the complications of coronary artery disease. The lack of benefit against coronary artery disease may result from failure to reduce other risk factors or because the drugs employed increased coronary risk. It can be taken as axiomatic that effective preventive antihypertensive therapy is more likely with drugs with mechanisms and sites of action that are focused on the underlying pathophysiology than with drugs that lower blood pressure by means unrelated to the hypertensive process. Adrenergic predominance plays a major role in the initiation and maintenance of essential hypertension and, consequently, the alpha-adrenergic receptor inhibitors were among the first substances to receive serious consideration as antihypertensive agents. However, since these drugs are nonselective, feedback control of transmitter norepinephrine was lost and, consequently, the clinical expectations of the early alpha-adrenergic receptor inhibitors in the treatment of high blood pressure were not fulfilled. The discovery of selective postjunctional alpha 1-adrenergic-receptor inhibitors, such as prazosin and doxazosin, which preserve feedback control of transmitter norepinephrine release, was the crucially important step in the development of specific drugs to combat the hyperactivity of adrenergic vasoconstrictor nerves in hypertension. These drugs have been shown to normalize hemodynamics in hypertensive patients. They lower blood pressure through a reduction in peripheral resistance at rest and during exercise, independent of changes in heart rate and blood pressure, with minimal reflex activation or tolerance development. Alpha 1-adrenergic-receptor inhibitors, such as prazosin and doxazosin, represent an attractive choice for initial therapy in all grades of hypertension and are especially appropriate in hypertensive patients with congestive heart failure, asthma and chronic obstructive airways disease, renal impairment, diabetes mellitus, hyperlipidemia, benign prostatic hyperplasia, or gout, and in those involved in vigorous work, sports, or exercise. There are no known contraindications to these drugs, except in patients who are sensitive to quinazolines.

Exposure to lead results in accumulation in proximal renal tubular lining cells in the form of morphologically discernible inclusion bodies which are lead-protein complexes. Acute nephrotoxicity consists of proximal tubular dysfunction and can be reversed by treatment with chelating agents. Chronic lead nephrotoxicity consists of interstitial fibrosis and progressive nephron loss, azotaemia and renal failure. Potential complications of lead nephropathy include gout and hypertension. Cadmium accumulates in renal tubular lining cells bound to metallothionein, a small protein containing 30% cystine. Metallothionein protects against nephrotoxicity by binding cadmium in a nontoxic form. Renal tubular dysfunction and chronic interstitial fibrosis occur when cadmium levels in the renal cortex exceed the critical concentration of about 200 micrograms/g. Recommendations are made for specific research needs.

The best definition of risk factors for renal injury, irrespective of the aetiological agent, comes from observations in patients with acute renal failure. From such observations, two subdivisions have evolved, i.e., acute insults and host risk factors. Acute renal insults include: hypertension, sepsis, use of nephrotoxic drugs (e.g., aminoglycoside antibiotics and contrast media), haemoglobinuria or myoglobinuria, liver disease and extracellular volume depletion. Host risk factors include: advanced age, hypertension, gout and hyperuricaemia, diabetes mellitus, chronic renal failure and use of diuretics. Furthermore, the mechanism of acute renal injury can be correlated with different risk factors: for a tubular toxic agent, acting either directly on the cells or haemodynamically, a dose-dependency is characteristic; while for immunologically mediated injury, genetic predisposition is more important. The identification of risk factors for chronic toxic injury is confounded by the possibilities of multiple episodes of subclinical renal injury, the distinct possibility that a major component of the ageing process may be a loss of renal reserve, and a progressive body burden, of, e.g., cadmium, which may deplete intrinsic protective mechanisms. However, clinically relevant risk factors can alert the clinician to exercise additional caution when prescribing medications that are potentially nephrotoxic. Such factors include dehydration, pre-existing renal disease, age, co-existing diseases that cause renal ischaemia, gender, concomitantly administered drugs, and electrolyte abnormalities.

The calcium antagonists are effective and safe agents for the treatment of arterial hypertension. They are well tolerated by the patients. In contrast to other types of antihypertensive agents, they cause few metabolic disturbances. They can be combined with diuretics, beta-blockers, and angiotensin-converting enzyme (ACE) inhibitors. They can be safely prescribed to patients with hypertension and concomitant diseases such as diabetes mellitus, chronic obstructive lung disease, congestive heart failure, gout, renal failure, peripheral atherosclerotic disease, or Raynaud's phenomenon. Dietary sodium restriction during antihypertensive therapy with calcium antagonists is not required for optimal antihypertensive efficacy. The second generation of calcium antagonists especially the dihydropyridine analogues that have greater potency and vascular selectivity, and a longer duration of action, will optimize the treatment of hypertension. Their antiatherosclerotic, antiplatelet, and "antitrophic" effects in experimental models for atherogenesis and hypertension hold great promise for the future since, so far, there has been no major success in reducing the incidence of coronary death by the treatment of hypertension.

Whereas up to the end of the last century overweight reflected the privilege of the high society and her relative good health, the recent epidemiological studies have assessed the relations between body weight and general or cause specific morbidity and mortality. The major diseases associated with obesity are hypertension, atherosclerosis and diabetes, as well as certain types of cancer. Less well known complications include hepatic steatosis, gallbladder diseases, pulmonary function impairment, endocrine abnormalities, obstetric complications, trauma to the weight bearing joints, gout, cutaneous diseases, proteinuria, increased hemoglobin concentration and possibly immunologic impairments. From these wide epidemiological studies arise the definition of obesity: with an excess of 20% beyond the desirable weight, the complications bound to the overweight become statistically more frequent. Over there a U or J shaped curve illustrates the relation between the overweight and the degree of these various complications. An excess of 45 kg or more represents the critical level which defined "morbid obesity" with its own complications, the most important are sudden unexplained death, ventilatory disorders, circulatory congestion and functional limitations in activities of daily living and of course psychological consequences. When for certain complications, such as diabetes, the relationship with the overweight is evident, discrepancies between certain studies, especially for the cardiovascular diseases, had focused the attention on the regional patterns of fat distribution. Cross-sectional studies have shown abdominal obesity to be strongly associated with risk factors for cardiovascular disease, stroke and death independent of the total degree of obesity.(ABSTRACT TRUNCATED AT 250 WORDS)
