Recently atherosclerotic diseases, such as coronary heart disease and cerebrovascular disease have been considered as an important complication of hyperuricemia and gout. However, it is still controversial whether or not hyperuricemia is an independent risk factor of atherosclerotic diseases. On the other hand, several risk factors for coronary heart disease, for example hyperlipidemia and hypertension, are frequently observed in the patients with gout. Atherosclerosis in relation to hyperuricemia was discussed in view of definite and probable risk factors.

There are at least two groups of issues connected with an impact of a realization of the "Human Genome Project": a) philosophical; b) ethical, which can be divided into four groups: 1) the influence of DNA technologies on everyday applications of bioethical principles; 2) ethical aspects of genetic diversity; 3) ethical aspects of genetic screening; 4) somatic and germ-cell gene therapy; Unlike essential philosophical issues practical realization of issues in question can be largely expressed as only revitalization of old ones and concerns: the principle of justice-equal access and priorities; protection of reproductive choices; disclosure to patients and to relatives at genetic risk (disclosure and exclusion tests); prenatal diagnosis for "mild to moderate" diseases with and without genetic indication-commercialization; insurance policy; non-directive and directive genetic counseling. Maybe there are regional and other differences, but in practice, the main ethical issues are likely to involve screening for genetic risk of common diseases of adult life e.g. hypertension, diabetes, gout, dyslipoproteinemia, genes for premature atherosclerosis, etc. because of the possible direct impact on a patient, an implication for life-insurance, employers and commercial exploitation.

We report a 62-year-old man who developed coma and died in a fulminant course. The patient was well until May 1, 1996 when he noted chillness, tenderness in his shoulders, and he went to bed without having his lunch and dinner. In the early morning of May 2, his families found him unresponsive and snoring; he was brought into the ER of our hospital. He had histories of hypertension, gout, and hyperlipidemia since 42 years of the age. On admission, his blood pressure was 120/70, heart rate 102 and regular, and body temperature 36.3 degrees C. His respiration was regular and he was not cyanotic. Low pitch rhonchi was heard in his right lower lung field. Otherwise general physical examination was unremarkable. Neurologic examination revealed that he was somnolent and he was only able to respond to simple questions such as opening eyes and grasping the examiner's hand, but he was unable to respond verbally. The optic discs were flat; the right pupil was slightly larger than the left, but both reacted to light. He showed ptosis on the left side, conjugate deviation of eyes to the left, and right facial paresis. The oculocephalic response and the corneal reflex were present. His right extremities were paralyzed and did not respond to pain Deep tendon reflexes were exaggerated on the right side and the plantar response was extensor on the right. No meningeal signs were present. Laboratory examination revealed the following abnormalities; WBC 18,400/ml, GOT 131 IU/l GPT 50 IU/l, CK616 IU/l, BUN 30 mg/dl, Cr 2.1 mg/ dl, glucose 339 mg/dl, and CRP 27.4 mg/dl. ECG showed sinus tachycardia and ST elevation in II, III and a VF leads and abnormal q waves in I, V5, and V6 leads. Chest X-ray revealed cardiac enlargement but the lung fields were clear. Cranial CT scan revealed low density areas in the left middle cerebral and left posterior cerebral artery territories. The patient was treated with intravenous glycerol infusion and other supportive measures. At 2: 10 AM on May 3, he developed sudden hypotension and cardiopulmonary arrest. He was pronounced dead at 3:45 AM. The patient was discussed in a neurological CPC, and the chief discussant arrived at the conclusion that the patient had acute myocardial infarction involving the inferior and the true posterior walls and left internal carotid embolism from a mural thrombus. Post mortem examination revealed occlusion of the circumflex branch of the left coronary artery due to atherom plaque rupture and myocardial infarction involving the posterior and the lateral wall with a rupture in the postero-lateral wall. Marked atheromatous changes were seen in the left internal carotid, the middle cerebral and the basilar arteries; the left internal carotid and the middle cerebral arteries were almost occluded by thrombi and blood coagulate. The territories of the left middle cerebral and the occipital arteries were infarcted; but the left thalamic area was spared. The neuropathologist concluded that the infarction was thrombotic origin not an embolic one as the atherosclerotic changes were severe. Cardiac rupture appeared to be the cause of terminal sudden hypotension and cardiopulmonary arrest. It appears likely that a vegetation which had been attached to the aortic valve induced thromboembolic occlusion of the left internal carotid artery which had already been markedly sclerotic by atherosclerosis. It is also possible that the vegetations in the aortic valve came from mural thrombi at the site of acute myocardial infarction, as no bacteria were found in those vegetations.

Some epidemiological studies have associated tea drinking with several health benefits, while other such studies have been inconclusive. The liver enzyme, xanthine oxidase (XO) produces uric acid and reactive oxygen species (ROS) during the catabolism of purines. Excess of the former can lead to gout and of the latter to increased oxidative stress, mutagenesis and possibly cancer. Polyphenols are antioxidants, and it has been suggested that they can reduce oxidative stress by their antioxidant properties. We report here on the inhibition of XO by five tea catechins and two flavones. The Ki values (microM) and types of inhibition were catechin (C) (Ki = 303.95, uncompetitive), epicatechin (EC) (Ki = 20.48, mixed), epigallocatechin (EGC) (Ki = 10.66, mixed), epicatechin gallate (ECg) (Ki = 2.86, mixed) and epigallocatechin gallate (EGCg) (Ki = 0.76, competitive). The Ki of EGCg was similar to that of allopurinol (Ki = 0.30, mixed), the drug of choice for inhibition of XO in gout patients. Thus, tea catechins may act at.an earlier stage than has previously been suspected, by inhibiting ROS production, rather than only neutralizing the already formed ROS. This suggests a new mechanism whereby tea drinking may prevent oxidative stress related diseases, e.g. atherosclerosis and cancer.

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.

Green tea, the most popular beverage in Japan and China, contains epicatechin-derived compounds which have been characterized in some epidemiological studies as having protective effects against cancer. Epigallo catechin-O-gallate (EGCG), the most active epicatechin in green tea was previously found to block the in vitro growth of many cancer cell lines and in vivo to strongly reduce tumor growth in cancer-bearing animals. Today, green tea consumption by animals is shown to markedly reduce VEGF-induced angiogenesis, a neo-vascularization process occurring in several physio-pathological conditions. EGCG is also able to inhibit endothelial cell growth in vitro and angiogenesis process in vivo. Elsewhere, EGCG has been described as a potent inducer of apoptosis and an inhibitor of telomerase activity. Because EGCG is acting on different processes, it could trigger various molecular mechanisms of action. Its anti-oxidant properties could explain its antagonistic action in some inflammatory processes. In summary, although no direct molecular target has been so far elucidated for EGCG, the multi-potentialities of this molecule, along with its broad bioavailability, render it very attractive as a putative curative drug for various diseases such as dermatosis, gout, atherosclerosis and cancer.

Gout is an inflammatory response to deposition of monosodium urate crystals in and around joints. It is primarily a disease of adult men. In acute gout, treatment options include non-steroidal anti-inflammatory drugs (NSAIDs), colchicine and corticosteroids, administered either intra-articularly, orally or parenterally. Asymptomatic hyperuricaemia does not require specific treatment, but should prompt screening for atherosclerosis risk factors, and general lifestyle modification to reduce serum urate levels. Gout presents differently in the elderly. Both women and men are affected, attacks are frequently polyarticular and in the upper limbs, and the gout may be associated with diuretic use, hypertension and renal impairment. In patients with peptic ulcer disease, selective COX-2 inhibitors provide another treatment option. In the presence of renal impairment, allopurinol is the treatment of choice for urate lowering therapy, but doses of allopurinol and colchicine must be adjusted. Urate lowering therapy should only be used if recurrent episodes of gout occur despite aggressive attempts to reverse or control the underlying causes. It should not be introduced or discontinued during an acute episode of gout, and gout prophylaxis (NSAIDs or colchicine) should be prescribed during the introduction of urate lowering therapy.

Obesity tracks from childhood into adulthood, and the persistence of obesity rises with age among obese children. Early onset obesity was suggested as a risk factor for morbidity and mortality later in life. In both sexes, rates of diabetes, coronary heart disease, atherosclerosis, hip fracture and gout were increased in those who were overweight as adolescents. Especially in females, obesity at late adolescence was associated with several and relevant psychosocial consequences in adulthood. Finally, a higher mortality risk for all causes of death, especially atherosclerotic cerebrovascular disease and colorectal cancer, was demonstrated in males but not in females who were overweight during high school years. Although the persistence of excess adiposity from childhood to adulthood is a morbidity risk factor, it is not known if total body fat or body fat distribution is the main factor responsible. In particular, a specific role for the intra-abdominal adipose tissue (IAAT) in childhood, independently from that of total body fat, on morbidity risk in adulthood was not demonstrated yet. The association between childhood obesity and adult morbidity and mortality strongly suggests that a more effective prevention and treatment of childhood obesity should be pursued.

A 47-year-old man lost his consciousness and brought to our hospital by ambulance. On admission, he had aphasia and upper right limb paresis. Diffusion weighted MR image of the brain on admission showed multiple high intensity areas in the left middle cerebral artery (MCA) territory. Brain angiography performed on the 2nd hospital day revealed the left MCA severe stenosis. We started intravenous antithrombotic therapy on the 1st day. The left carotid angiography on 12th day demonstrated that the left MCA stenosis was improved. He had medical history of hypertension, diabetes mellitus and gout. But he had only slight atherosclerosis, and had no arrhythmia and patent foramen ovale. Blood chemistry test showed marked hypoproteinemia and hyperlipidemia, and urine examination showed proteinuria. He was diagnosed as nephrotic syndrome for the first time. Nephrotic syndrome brought hypercoagulability, so we suspected that nephrotic syndrome concerned with brain infarction.

Previous studies have suggested that there is an increased incidence of degenerative vascular disease in patients with gout and an increased rate of turnover of blood platelets in patients and animals with atherosclerosis. A disturbed uric acid metabolism and "secondary" gout have long been known to occur with bone marrow diseases. A study of platelet economy and blood clotting factors in subjects with primary gout was therefore undertaken.Twenty-two male subjects with gout but with no clinical evidence of vascular disease were studied. Half of these had a negative family history for vascular disease and half had less fortunate ancestors. The most striking differences were found when gouty patients with a negative family history for vascular disease were compared with similar control subjects. The mean platelet half-life was 2.85 days in the gouty subjects and 3.74 days in the controls. The mean platelet turnover (number/c.mm./day) was 58,750 in gouty subjects, 42,370 in controls. Platelet adhesiveness and plasma thromboplastic activity were correspondingly increased in the gouty subjects. Control subjects with a positive family history all showed relatively active clotting system and platelet turnover, similar to the values found in atherosclerotic subjects. The data indicated that there is increased platelet destruction and production in some patients with primary gout. The relation between this anomaly and the vascular disease, and disturbed urate metabolism in gouty subjects, remains to be investigated.
