We studied the frequency of heart disease and association with other coronary risk factors in 243 consecutive patients (124 male and 119 female) suffering from arterial hypertension (Group HT). The mean age was 67.5 +/- 9.6 years. This group was compared to a group of 357 subjects (217 male and 140 female) without arterial hypertension (Group noHT) and mean age of 63.5 +/- 13 years. In our group the patients with arterial hypertension presented smoking habits in 35%, hypercholesterolemia in 22%, left ventricular hypertrophy (LVH) in 18%, alcoholic habits in 15%, hypertriglyceridemia in 12%, diabetes in 9% and hyperuricemia in 7%. 15% of the patients suffering from arterial hypertension turned out with coronary heart disease (62% angina and 38% myocardial infarction), 19% with atrial fibrillation and 13% with heart failure. Compared to the patients without hypertension we found significant statistical correlation with the age (67.5 +/- 9.6 HT and 63.5 +/- 13 no HT, p < 0.001), the LVH (18% HT and 4% no HT, p < 0.001) and number of coronary risk factors (2 +/- 1 HT and 1.1 +/- 0.9, p < 0.001). The percentage of people without cardiac disease is lower among the group with arterial hypertension (53% HT and 71% noHT, p < 0.001), showing as well a higher incidence of atrial fibrillation (19% HT and 11% noHT, p < 0.05) and heart failure (13% HT and 7% noHT, p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

The long-term management of cyanotic congenital heart disease requires treatment of raised haematocrit (> 65%) whilst conserving the quality of the red blood cells [mean corpuscular volume, mean corpuscular haemoglobin concentration (MCHC)]. Since 1975, the author has chosen chemotherapy (hydroxyurea, pipobroman) as first-line treatment, reserving iron supplements, phlebotomy and platelet antagonists as adjuvant therapy. Pre-treatment data of 170 patients showed: a high prevalence of hypochromic microcytosis due to iron deficiency and of thrombopaenia, in relation to the severity and duration of the polycythaemia. Hyperuricaemia was greater than 420 mumol/l in 67% of cases; effort tolerance and hyperviscosity were related to the haematocrit and iron deficiency. One hundred and forty seven patients were followed up for a total duration of 769 years of chemotherapy. Clinical tolerance was good: biological tolerance was marked by a high frequency of thrombocytopaenia requiring withdrawal (10 cases) or reduction of treatment (34 cases). The causes of the 39 deaths observed are analysed: none was related to the hydroxyurea or pipobroman. The treatment or follow-up was stopped in 29 cases: the reasons are reported. Seventy eight patients under treatment had a favourable outcome with normal social reinsertion in 74 cases. This efficiency was related to maintenance of a haematocrit < 65%, to correction of the iron deficiency and increase in the MCHC. These results were obtained with an average dosage of 19 +/- 4.5 mg/kg/day of hydroxyurea (69 patients). By slowing erythropoiesis, chemotherapy reduces the indication of phlebotomy, so reducing iron loss: it also inhibits excessive bouts of polycythaemia in cases of iron therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Hyperuricemia is commonly recognized in adolescents and adults with cyanotic congenital heart disease. We report a case of a male infant with hyperuricemia, Taussig-Bing anomaly, and interruption of the aortic arch. The patient underwent correction of interrupted aortic arch and pulmonary arterial banding at the age of 7 days. Hyperuricemia appeared when he was 2 months old (max 17.7 mg/dl) and persisted until he underwent a Jatene operation at the age of 10 months. The hyperuricemia improved gradually after the disappearance of hypoxia and polycythemia. The laboratory findings suggest that hyperuricemia can result from uric acid overproduction due to secondary polycythemia, impairment of uric acid excretion by the kidney, or the acceleration of anaerobic metabolism. Allopurinol and benzbromarone together were partially effective treatments for hyperuricemia in this patient with cyanotic congenital heart disease.

This study examines the exacerbating factors of hyperuricaemia in patients with cyanotic congenital heart disease (CCHD). We studied 59 CCHD patients aged 1 month-30 years. The following variables were assessed: serum uric acid levels, red blood cell count, haemoglobin, hematocrit, partial oxygen pressure and arterial oxygen saturation. Uric acid excretion and renal function were also measured in ten patients with serum levels of uric acid greater than 8 mg/dl (hyperuricaemia group). Serum uric acid level correlated significantly with age and severity of polycythaemia. However, it did not correlate with partial oxygen pressure or arterial oxygen saturation. Uric acid excretion was measured in hyperuricaemia group. Urinary uric acid excretion (24 h) was within normal limits in infants but markedly lower in patients over 15 years of age. The aetiology of hyperuricaemia and decreased uric acid fractional excretion and clearance in infants appears to be secondary to diminished excretion of uric acid in concert with uric acid overproduction. Hyperuricaemia in adolescents and adults with CCHD, however, results mainly from age-related impairment of uric acid excretion.

Hypertension in the elderly features differently from its younger counterpart in terms of diagnosis, associated condition, atypical manifestation, management and complication. Epidemiological study in this increasing age group in the community is, therefore, needed. 334 elderly subjects living in various parts of Bangkok were randomly recruited by appointment at 7 geriatric day centers situated in local health offices of Bangkok Metropolitan Authority. Each subject received blood tests before being interviewed and measured by digital sphygmomanometer. Blood pressure and heart rate changes were recorded during lying, sitting and standing. The prevalence of hypertension was 36.5 per cent, 33.2 per cent were already aware of its existence while 3.3 per cent were newly detected by the survey. Isolated systolic hypertension, a unique subtype found in the elderly, was 4.5 per cent of all or 37.5 per cent among the hypertensive group. The associated medical conditions among the case group were diabetes mellitus 22.9 per cent, hyperlipidemia 13.9 per cent, hyperuricemia 33.3 per cent and heart disease 18.0 per cent. As far as postural hypotension is concerned, 14.8 per cent of case group whereas 11.3 per cent of the control group were affected. On the other hand, the symptom of postural dizziness was found to be 31.1 per cent and 55.2 per cent in the case and control group respectively. Following the statistical logistic regression analysis, the independent associated factors in the hypertension group were: history of hyperlipidemia, increased serum uric acid and poor heart rate response after standing. These findings, as parts of the multiple pathology and potential complications prevalent among this group, should be of concern by any physician looking after the elderly.

To establish a practical weight management program for mariners in the Japan Maritime Self-Defense Force (JMSDF) Fleet Escort Force, the relationship between morbidity and body mass index (BMI) was studied. To estimate morbidity, 10 medical problems were used as indices (hyperlipidemia, hyperuricemia, diabetes mellitus, lung disease, heart disease, upper gastrointestinal tract disease, hypertension, renal disease, liver disease, and anemia). A curvilinear relationship was found between morbidity and BMI, in which a BMI of 17.5 was associated with the lowest morbidity. This curvilinear pattern was more complex than a curve reported previously for Japanese civilians. Using the present curve and aiming for a BMI of 17.5 will help in the design and implementation of a practical management program for health promotion in the JMSDF.

The aim of the present study is to establish a highly sensitive method for the determination of uric acid (UA) in human saliva. The monitoring of UA levels in less invasive biological samples such as saliva is suggested for the diagnosis and therapy of gout, hyperuricemia, and the Lesch-Nyhan syndrome, and for detecting such conditions as alcohol dependence, obesity, diabetes, high cholesterol, high blood pressure, kidney disease, and heart disease. Reversed-phase high-performance liquid chromatography with electrochemical detection (HPLC-ED) was employed for the determination of UA obtained by solid-phase extraction from saliva. To quantify UA, we compared the ED efficiencies of an amperometric ED (Ampero-ED) with a single electrode and a coulometric ED (Coulo-ED) with a multiple electrode array. The results showed that the detection limits (S/N=3) were 3 nM for Ampero-ED and 6 nM for Coulo-ED, and the linearity of the calibration curves of 60-6000 nM had correlation coefficients exceeding 0.999. In addition, the total analytical time was 10 min. In the sample preparation of UA in saliva, an Oasis MAX solid-phase cartridge was used. The recoveries of UA spiked at 0.6 and 3 microM in saliva were above 95% with a relative standard deviation (RSD) of less than 15%. Therefore, the present method may be used in the routine and diagnostic determination of UA in human saliva.

We evaluated the association between pulse pressure (PP) and cardiovascular risk factors in a screened cohort. Individuals who were receiving medications for hypertension or heart disease, who had no ECG record, or who had a record of arrhythmia were excluded. In total, 8,508 subjects (5,299 men and 3,209 women; age range, 18 to 89 years) were studied. Subjects were divided into four PP classes: PP.1 (PP < or = 40 mmHg, n=2,127), PP.2 (40 < or = PP < or = 44 mmHg, n=2,127), PP.3 (44 < or = PP < or = 50 mmHg, n=2,127) and PP.4 (50 mmHg < or = PP, n=2,127). Multiple regression analysis was used for evaluating the association between PP and cardiovascular risk factor or lifestyle. In men, the regression coefficient was 0.27 for age, 2.50 for diabetes mellitus, 0.33 for uric acid, 0.20 for body mass index, 0.07 for heart rate, -0.83 for current smoking habit and 1.23 for habitual drinking. In women, the regression coefficient was 0.37 for age, 4.09 for diabetes mellitus, 0.42 for body mass index, 0.14 for heart rate, and 0.84 for habitual exercise. In both men and women, PP was significantly increased in association with an increase in the number of risk factors (diabetes mellitus, obesity, current drinking status, heart rate, and hyperuricemia). In conclusion, higher PP was associated with cardiovascular risk factors. These associations were similar in both men and women.

A 72-year-old white man presented with a large cutaneous tumor on his back. The patient said the lesion, mostly asymptomatic, had increased in size for about 7 years. Physical examination revealed a vegetating mass (Figure 1), partially ulcerated, measuring 30 x 20 cm, which easily dripped serum and blood, with small necrotic areas and a sclerotic border. Perilesional skin appeared edematous, probably owing to inflammation and impaired lymphatic flow. Clinically, there was no evidence of lymph node involvement. His family history was noncontributory. Hematologic examination revealed hypochromic microcytic anemia. Laboratory test results showed hyperuricemia and hypercholesterolemia. The patient's history revealed mild hypertension, ischemic cardiopathy treated with percutaneous transluminal coronary angioplasty and anticoagulant drugs, and moderate chronic renal insufficiency. Histologic examination of a biopsy specimen taken from the margin of the lesion displayed a superficial area of ulceration and invasion of the deeper dermis and subcutaneous tissue (Figure 2A and Figure 2B). The tumor mostly showed an adenoid pattern: gland-like structures and cystic spaces sometimes containing amorphous or granular material, surrounded by strands of basaloid cells devoid of any peripheral palisading (Figure 2C). In some areas, the adenoid pattern coexisted with infiltrated areas characterized by thin and elongated strands or cords of basaloid cells with irregular and jagged peripheral contours within a fibrous or edematous stroma (Figure 2D). Basaloid cells often revealed nuclear atypia, marked pleomorphism and hyperchromatism (Figure 2C and Figure 2D). Therefore, a diagnosis of basal cell carcinoma, adenoid subtype, was made. Magnetic resonance imaging showed a 10-cm wide thickening of the subcutaneous layer on the lumbar region, with a partial neoplastic infiltration of the muscle fascia. No evidence of metastases was found with a total body computed tomography scan. Because the patient was taking anticoagulant drugs and had unstable renal and cardiac function, surgical treatment was at least temporarily excluded, and the patient was referred for radiation therapy.

In humans, the hepatic end product of purine metabolism is uric acid. Serum uric acid levels physiologically and gradually rise during human lifetime. Hyperuricemia also arises from excess dietary purine or ethanol intake, decreased renal excretion of uric acid, tumor lysis in lymphoma, leukemia or solid tumors, and sometimes pharmacotherapy. The definition of hyperuricemia is currently arbitrary. Hyperuricemia is associated with chronic kidney disease, arterial hypertension, coronary artery and heart disease, cerebrovascular disease and diabetes mellitus. Xanthine oxidase, a hepatic enzyme, catalyzes the production of uric acid, nitric oxide, and reactive oxygen species, which potentially damage deoxyribonucleic acid, ribonucleic acid and proteins, inactivate enzymes, oxidize amino acids and convert poly-unsaturated fatty acids to lipids. This is believed to contribute to atherosclerosis, endothelial dysfunction, renovascular hypertension, and cardiovascular disease. Xanthine oxidase inhibition efficiently blocks uric acid generation, and this improves glomerular filtration rates, systemic blood pressure, and cerebro-cardiovascular outcomes. Here, data from animal, in vivo, retro- and prospective, and interventional studies are reported.
