Coffee as a rule develops stimulating effects on the central nervous system, heart and circulation which are mainly caused by caffeine. In certain cases coffee may also have a sedative effect and sometimes even it is useful to fall asleep quickly. Furthermore coffee may be advantageous in the treatment of some functional disorders caused by lacking of dopamine, because coffee is able to increase the dopamine formation in brain. Concerning the effects of coffee in the gastrointestinal-tract and liver-bile system caffeine is only of secondary importance. Hereby certain roasting substances, possibly also chlorogenic acid or caffeic acid should be responsible for the stimulating effects observed in these organs. These stimulating effects could be caused whether directly or indirect e.g. by liberating gastrin or other gastrointestinal hormones. Vitamin niacin, which is formed in greater amounts from trigonelline during the roasting process, may also be important from the nutritional standpoint. Therefore coffee may be prescribed as a true drug in cases of deficiency in vitamin niacin or also in the pellagra disease. By extensive epidemiological studies performed lately it could be demonstrated that there exists no correlation between coffee consumption and certain risk factors as hypertension, heart infarction, diabetes, gout or cancer diseases. Furthermore there was no evidence that coffee or its caffeine content are able to induce genetic alterations or even malformations.

We investigated the prognosis of 153 hypertensive patients, whose initial concentration of serum uric acid had been evaluated. One hundred and seventeen subjects could be followed up after 4 years and 16 of them died during the follow-up period. Cerebrovascular disease was seen in 6 subjects, 4 of whom died from the disease. Myocardial infarction and heart failure occurred in 9 and 7 of them died as a result. The frequency of these diseases was greater among the hyperuricemic group and 8 of the 11 who died belonged to this group. Four men were struck by gouty attacks. They were all hyperuricemic and had been proven to have at least one family member with asymptomatic hyperuricemia and/or gout. It is reasonable to regard the presence of hyperuricemia as one of the poor risk factors for vascular diseases. I addition, we must investigate more closely personal and family histories of gout when we see hyperuricemic subjects, regardless of absence of gouty symptoms.

We studied the prevalence and the risk factor among the patients of gout in Mexico. Research was conducted in the National Institute of Cardiology and in our private practice. Prevalence of hiperuricemia and gout in the Institute of Cardiology was of 1% (970 out of nearly 100,000 patients). We divided those cases of two subgroups: Reumatology patients (333) and Cardiovascular patients (529). In the first group primary gout was (96.3), and (50.32% in the second. Risk factor was quite different too: nephropathy 9.9%, lithiasis 9.3%, pyelonephritis 2.7%, cardioangiosclerosis 12.9%, aortosclerosis 6.6%, coronary insufficiency 6.3%, myocardial infarction 0.9%, arterial hypertension 24.6% obesity 56.1% and diabetes 9.9% in the Reumatology group; in the Cardiovascular one, nephropathy 14.3%, lithiasis 12.2%, pyelonephritis 7.1%, cardioangiosclerosis 62.7%, aortosclerosis 31.7%, coronary insufficiency 24.9%, myocardial infarction 29%, arterial hypertension 51%, obesity 54.8% and diabetes 20.4%. Among the private practice patients prevalence was of 10.1% (961). In an early age (39 years) in men and a later one for women (53 years). Other characteristics of epidemiology and risk factor are: primary gout 89%, atherosclerosis 5%, coronary disease 4.6%, lithiasis 4.7%, nephropathy 2%, pyelonephritis 1%, obesity 43%, and diabetes 4.6%. In an small group of patients of our private practice we made an exhaustive study of risk factor and the metabolic disorder of lipids. We found the following frequency: 9.3 of nephropathy, 31.2% of lithiasis, 18.7% of pyelonephritis, 68.9% of cardioangiosclerosis, 46.8% de coronary insufficiency, 9.3% of myocardial infarction, 68.7% of arterial hypertension, 68.7% of obesity and 18.7% of diabetes. In the lipid profile we found an increase in triglicerids and prebeta lipoprotein. We have amply discussed the relation between hiperuricemia and pathology considered as a risk factor from the genetic point of view as well as the metabolic and circumstancial aspect. From all that we concluded that risk is multifactorial.

A study of the clinical profile of gout-diagnosed patients was undertaken within general practice in Great Britain. At the time of the first attack of acute gouty arthritis, the mean age was 52.3 years and 15.6% of the total 1077 patients were female. Males had an earlier clinical onset than females and the average frequency of attacks of acute gouty arthritis was 0.91 per patient year. Ten per cent of the cases were believed to be secondary gout, with diuretic therapy the most frequent cause. The sample showed a highly significant association between gout and the higher social classes, a family history among blood relatives in 23% of cases, tophi were noted in 4.6% of cases where sought and 38.2% of cases were 10% or more overweight and significantly heavier than a non-gouty population. The great toe joint was most frequently involved, both in the first episode and in all acute episodes combined. The most frequently occurring associated chronic condition was hypertension which was present in 27.8% of cases. Renal stones occurred in 6.1% and renal impairment in 2.2%. Only 20.4% of the patients were referred to hospital, with the younger being referred more frequently than the older. Those with joint involvement other than the great toe had a greater chance of being referred, as did those who also had angina pectoris, myocardial infarction and hypertension. Allopurinol appeared to be the drug of choice for long-term control therapy and phenylbutazone for the acute attack.

A study of the distribution of the various risk factors for coronary artery disease as a function of the age and sex of a homogenous population of 316 patients has brought to light the following findings: -- These was found to be a greater incidence (statistically significant) of hypertension disorders of glucose metabolism obesity and hypercholesterolaemia in the females, and of tobacco consumption (cigarettes) and, to a lesser extent, of hypertriglyceridaemia and of gout in the males; -- The females who 'tot up' risk factors have their myocardial infarction at a greater age than the males -- The risk factor which separates the two sexes in the consumption of cigarette tobacco. These findings agree with those already in the literature.

As part of a cardiovascular survey study on the relationships between physical fitness and coronary heart disease, 5249 Copenhagen males aged between 40 and 59 were interviewed to identify a history of gout. Subjects who had experienced attacks of painful swelling, with abrupt onset and remission in one to two weeks, diagnosed and treated as gout by their own physician, were regarded as having experienced gout. In an initial cross-sectional examination, 86 men fulfilled the criteria. At a one year follow-up examination it was discovered that 56 men had had gout during the year of observation. Among these 18 were new cases. At the end of the study a total of 104 men had experienced gout and these were compared, with respect to the continuously distributed variables, those 104 gout subjects were compared to 208 computer selected age-matched controls drawn at random from the entire sample. The gout cases were found to have higher relative weights, higher diastolic blood pressure and lower levels of physical fitness estimated by use of a bicycle ergometer test. Angina pectoris occurred more frequently among the gout cases than among controls. No significant differences in the occurrence of myocardial infarction, intermittent claudication or renal stones were found. The habits of smoking and coffee consumption were equal in gout cases and controls. Alcohol consumption and consumption of drugs were higher in gout cases than controls. Gout was the most frequent in the lowest social classes.

The etiology of hyperuricemia following myocardial infarction was investigated by uric acid kinetic studies carried out on seven male patients following myocardial infarction and on two control subjects. The patients selected had uncomplicated myocardial infarction and were maintained on a low-purine diet. Measurements of uric acid pool size and turnover rates using 2-C14 uric acid were made, commencing on days 2-5 following myocardial infarction. Initial concentration of serum uric acid ranged from 2.9 to 9.8 mg/100 ml. Uric acid pool size was elevated in six of seven patients. Five had a pool size of from 36.9 to 79.6 mg/kg, while the single gouty subject demonstrated 104 mg/kg compared with 12.6 and 16.8 mg/kg for the control subjects. Turnover rates were also increased, ranging from 1036 to 2772 mg/day (controls, 612 and 872 mg/day). Twenty-four-hour urine uric acid excretions ranged from 358 to 623 mg/24 hr. Serum lactic acid concentration was normal (1.03 plus or minus 0.17 muM/ml), and endogenous creatinine clearance in all cases was 77.9 ml/min or greater. These data suggest that following myocardial infarction there is an expansion of the uric acid pool with an increased uric acid turnover rate. Only the patient with a previous history of gout had uric acid excretion outside the normal range.

1) Patients with myocardial infarction constituted 2.36% of all the hospitalized patients during 1961-1968. The mortality of the hospitalized patients with myocardial infarction during the same term was 19.1%. The ratio of the male to female patients with myocardial infarction was 5.2. 2) As the risk factors of myocardial infarction, the following items were considered to be of importance: 1. gout in past history, 2. angina pectoris in family history, 3. diabetes mellitus in family history, 4. cigaret smoking over 40 pieces per day, 5. diabetes mellitus in past history, 6. administrative occupation, 7. serum cholesterol level over 250 mg/100 ml, 8. obesity of 20% excess over standard body weight, 9. hypertension in family history. 3) According to the statistical analysis, several groups of risk factors and interrelationship of risk factors are recognized.

The authors report on 14 cases of osteonecrosis of the femoral head (ONFH) in patients suffering from gout. The cases of association were discovered over a period of 10 years among 232 patients with ONFH and 651 with gout. The necrosis had no particular characteristics except that there was a clear preponderence in males and a slight tendency to be bilateral; it occurred, perhaps, at a slightly earlier age. The patients with gout did not show any special clinical features ; the gout always preceded the necrosis, on average by 7 1/2 years. There was no obvious history of painful crises in the hip that could be attributed to the acute gout, except in one case. The excess of urate was detected by the baseline level of uricaemia (91 mg/litre on average), by the frequency of tophus (4 out of 14), and by the frequency of urinary lithiasis (2 out of 14), and did not appear to be any greater in the patients with gout and ONFH than it was in the whole of the population of gout patients. In those patients in whom it was estimated, the lipid analysis showed most frequently an increase in total lipids, in triglyceridaemia, and in cholesterolaemia. In the 5 patients in whom the investigations were sufficiently detailed, the dyslipidaemia was of Frederickson type II + IV (mixed hyperlipidaemia according to de Gennes' classification). Different physiopathological hypotheses are discussed by the authors, notably those concerned with micro-particulate fatty emboli (lipomicrons), which may obstruct, among others, the terminal arteries of the femoral head. Of the 6 patients for whom it was possible to obtain information, for an average period of 10 years since the onset of the necrosis, 2 had presented with untreated hyperlipidaemia and a severe general vascular illness (myocardial infarction in one case and regressive hemiplegia in the other). These findings lead to the conclusion that correction of the hyperlipidaemia by diet is indispensable to ensure the long-term survival of these patients.
