A forty-two years old male underwent an aortic arch replacement for an emergency treatment of dissecting aortic aneurysm (DeBakey type I). Separate cardiopulmonary bypass was used with main arterial inflow cannula inserted to right femoral artery. After the operation, ischemia of the right lower extremity led to acute renal failure due to myonephropathic-metabolic syndrome. Peritoneal dialysis, hemodialysis, and continuous arterio-venous hemofiltration were performed. Renal failure improved gradually. At the diuretic phase serum calcium concentration began to rise. Inspite of large amount of fluid and furosemide injection it became higher and finally reached to 20 mg/dl level. Calcitonin injection (320 mu/day) was very effective. In 2 months after surgery serum creatinine and calcium concentrations went down to normal range. Abnormalities in calcium metabolism are frequent in rhabdomyolysis-induced acute renal failure. However, it is rare to encounter such a remarkable hypercalcemia as seen in this patient. When treating MNMS we should pay attention to the changes of serum calcium concentration.

The removal of serum myoglobin with extracorporeal circulation using a column filled with methylmethacrylate-divinylbenzene (MMA-DVB) was studied in experimentally induced myonephropathic metabolic syndrome in the dog. All animals showed marked edema in the hind limbs and degeneration or necrosis of the adductor muscle 5 hours after the reestablishment of arterial flow. The serum levels of myoglobin, creatinine phosphokinase, glutamic oxaloacetic transaminase and aldolase increased linearly after the reperfusion of blood in the group of animals which received no extracorporeal circulation (group 1). Sediments of numerous myoglobin casts in the renal tubules and immunoreactive myoglobin in the renal epithelium of almost all the tubules were seen in 4 out of 5 cases. In the group of animals reperfused with extracorporeal circulation using the MMA-DVB column, serum myoglobin was adsorbed selectively by the column and showed a significantly lower value at 0.5, 1, 2 and 3 hours than that of the group 1 animals. Concomitantly, the immunoreactive myoglobin was absent or scant in the renal epithelium of the proximal convoluted tubule. The present study therefore indicates that extracorporeal circulation using the MMA-DVB column is useful for the removal of serum myoglobin from experimentally induced myonephropathic metabolic syndrome.

Coincident pathological parameters were selected from 24 laboratory-diagnostic parameters of a second stage of diagnostics after x-rays screening concerning heart and vessel diseases tested by a check representative constellation in the shape of relative frequency was determined. For the parameters cholesterol, uric acid and glucose, belonging to the metabolic syndrome, it was possible to demonstrate relations to the erythrocyte sedimentation rate. The transaminases ASAT and ALAT especially showed correlations of pathological values among one another. There were found out one-sided relations for instance concerning the proportion of transaminases, thymol turbidity test as well as creatinine to the erythrocyte sedimentation rate. The connections as has been proved appeared in female cardiac patients in a more distinct way. The results, which were interpreted in the context of a further mathematic-statistical analysis, allow the conclusions for an efficient indicational application of clinical chemical research methods in chronic heart and vessel diseases in practice.

The cardiovasculary risk profile of 138 old grown long term diabetics (mean age 71,1 years, mean duration of the disease 19,9 years) was analysed in the frame of the so called metabolic syndrome and put in relation to the corresponding value of serum creatinine. With increasing concentration of creatinine the mean value of diabetes-associated cardiovasculary risk factors grew with old age, where only the frequency of hyperuricaemia correlated positively to the creatinine level. With comparable level of uric acid in serum the part of pathological increasing of creatinine in older age was more marked distinctly than with younger long term diabetics et respective time of disease (n = 112, mean age 45,7 years, mean duration of the disease 19,6 years). 42,0 per cent of the younger and 60.9 per cent of the older long term diabetics showed increased values of serum creatinine (p less than 0,01). The reduction of the cardiovasculary risk factors should also be forced with old grown long term diabetics.

Of 250 diabetics with a duration of the disease between 15 and 54 years the relations between the renal function and the cardiovascular risk profile were examined. The clearly increased serum creatinine values the frequency of persons with overweight was lower than in diabetics with very favourable creatinine levels. The increasing concentration of the serum led to an increase of the frequency of hyperuricaemia, whereas the frequencies of hypertension hypertriglyceridaemia and hypercholesterolaemia did not show any significant changes. The habits of smoking of long-term diabetics with and without renal insufficiency did not differ from each other qualitatively. Particularly after the 50th year of age long-term diabetics more frequently had diabetic blood-relatives than newly detected diabetic patients of the same age. Patients with familial occurrence of diabetes (relatives of 1st degree) in comparison to diabetics without known diabetic relatives showed an identical cardiovascular risk profile, so that there is no influence of the heredity of diabetes on the formation of the non-diabetic sizes of influence of the metabolic syndrome.

We investigated the association between fasting insulin concentration--an indicator of insulin resistance in nondiabetic individuals--cardiovascular risk factors, and coronary heart disease in a study of 390 men in the town of Zutphen. In 1990, an extensive examination was carried out on the participating men (aged 70 to 89 years). Fasting insulin levels were determined and a number of other risk factors measured. Known and newly diagnosed diabetics were excluded from the data analyses. Fasting insulin concentration was significantly associated with levels of glucose, triglycerides, uric acid, serum albumin, creatinine, and fibrinogen as well as resting heart rate. Inverse associations with high-density lipoprotein cholesterol and factor VII activity were observed. These results were independent of confounding factors such as age, body mass index, ratio of subscapular to triceps skinfold thicknesses, cigarette smoking, physical activity, and alcohol consumption. Men with a fasting insulin level higher than 80 pmol/L (highest quartile of the distribution) had a significantly higher prevalence of coronary heart disease and especially of myocardial infarction. This result was independent of potential confounding variables as well as of possible intermediates (total and high-density lipoprotein cholesterol, hypertension, serum triglycerides, fasting glucose, and other risk factors related to fasting insulin) (odds ratio, 2.2; 95% confidence interval, 1.2-4.0). No association between fasting insulin level and hypertension or blood pressure was observed. These results show that fasting insulin is an important indicator of coronary heart disease in elderly men. Clotting factors, resting heart rate, uric acid, serum albumin, and creatinine may also play a role in this metabolic syndrome.

Microalbuminuria has been associated with cardiovascular risk factors, events, and mortality. It also clusters with hyperinsulinemia and the metabolic syndrome. How urinary albumin excretion and the fasting serum insulin level relate to coronary artery disease (CAD) has not been previously determined. In 308 patients undergoing elective coronary angiography, the albumin to creatinine ratio was measured in urine from an early morning void. The fasting serum insulin level was also determined. CAD was assessed by angiography. Urinary albumin excretion was 28 +/- 5 mg/g (mean +/- SE) in patients with CAD and 10 +/- 1 mg/g in those without CAD (P < 0.001). Fasting serum insulin levels were also greater in patients with CAD compared with those without CAD; 20 +/- 3 and 13 +/- 1 microU/mL, respectively (P = 0.016). Urinary albumin excretion and fasting serum insulin levels increased progressively with severity of CAD. In patients without diabetes (n = 255), significant relationships of urinary albumin excretion and the fasting serum insulin levels to CAD were observed, but they were more pronounced when patients with diabetes (n = 53) were included. In multiple regression analysis, the odds ratios for severe CAD were 2.2 (95% confidence interval, 1.1 to 4.5) for microalbuminuria and 2. 2 (95% confidence interval, 1.3 to 3.8) for hyperinsulinemia. In summary, urinary albumin excretion and the fasting serum insulin levels were directly related to angiographic evidence of CAD. Microalbuminuria and hyperinsulinemia predict a significantly elevated risk for coronary atherosclerosis.

The metabolic syndrome is characterized by a clustering of cardiovascular risk factors including type 2 diabetes mellitus, hypertension, dyslipidemia, and obesity. Elevated plasma insulin and urinary norepinephrine (noradrenaline) and reduced urinary epinephrine (adrenaline) excretion are associated with obesity in Caucasian populations. We examined the interrelationships between obesity, plasma insulin, and urinary catecholamine excretion in Chinese subjects with various components of the metabolic syndrome. A total of 577 Chinese subjects (aged 38 +/- 10 years; 68% with type 2 diabetes mellitus, hypertension, dyslipidemia, obesity, and/or albuminuria and 32% healthy subjects) were studied, all of whom had a plasma creatinine less than 150 micromol/L. The blood pressure, height, weight, waist and hip circumference, and fasting plasma glucose, insulin, lipid, and creatinine levels were measured. A 24-hour urine sample was collected for measurement of albumin and catecholamine excretion. The body mass index (BMI) and waist circumference were used as measures of general and central obesity, respectively. The insulin resistance index was estimated by the calculated product of fasting plasma insulin and glucose concentrations. Patients with an increasing number of components of the metabolic syndrome (type 2 diabetes mellitus, hypertension, dyslipidemia, obesity, and/or albuminuria) were more obese, hyperglycemic, dyslipidemic, and albuminuric and had higher blood pressure, plasma insulin, insulin resistance indices, and 24-hour urinary norepinephrine excretion but lower urinary epinephrine output (all P < .005). Increasing quintiles of BMI in the whole population or waist circumference in both sexes were associated with increasing trends for adverse lipid profiles, plasma insulin, insulin resistance indices, and urinary norepinephrine excretion but a decreasing trend for urinary epinephrine output (all P < .001). There were close associations between age, obesity, blood pressure, fasting plasma glucose, lipid, insulin, insulin resistance indices, and urinary catecholamine excretion. Using stepwise multiple regression analysis (all P < .001), 34% of the variability of the BMI and 45% of that of the waist circumference were independently related to gender (waist higher in males and BMI higher in females), increased plasma insulin, triglyceride, and urinary norepinephrine excretion, and decreased high-density lipoprotein (HDL) cholesterol and urinary epinephrine output. In Chinese subjects with different manifestations of the metabolic syndrome, hyperinsulinemia, insulin resistance, elevated norepinephrine, and reduced epinephrine excretion were closely associated with general and central obesity. Based on these findings, we postulate that complex interactions between the insulin and sympathoadrenal systems may lead to the development of obesity and the metabolic syndrome.

In order to evaluate the clinical characteristics of metabolic syndrome, a screening procedure was performed and in a cohort of middle-aged (40-60 years) hyperinsulinaemic (fasting plasma insulin > 15 microU/ml) and/or postprandial [120 min after 75 g glucose load] insulin > 45 microU/ml) subjects (n = 91; men/women: 38/53; age mean +/- SD 47.6 +/- 4.3 years; body mass index: 34.6 +/- 4.9 kg/m2; waist-hip ratio: 0.92 +/- 0.07; actual blood pressure 146 +/- 16/87 +/- 9 mmHg; fasting insulin: 24.2 +/- 11.3 microU/ml; postprandial insulin 125.5 +/- 103.8 microU/ml; serum LDL-cholesterol: 3.73 +/- 1.09 mmol/l; HDL-cholesterol: 1.12 +/- 0.30 mmol/l; triglycerides: 2.97 +/- 2.38 mmol/l; uric acid 279 +/- 79 mumol/l) plasma fasting homocysteine, vitamin B12 and folic acid levels were simultaneously determined. The values were separately evaluated according to the stages of glucose tolerance (normal glucose tolerance [n = 47]; impaired glucose tolerance [n = 24] and diabetes mellitus [n = 20]). Laboratory normal values were determined in 47 healthy subjects (control group, age: 45.0 +/- 7.8 years, men/women: 19/28). There was no significant difference between hyperinsulinaemic and control subjects regarding plasma homocysteine (9.28 +/- 3.81 mumol/l vs. 9.63 +/- 2.70 mumol/l), folic acid (8.5 +/- 5.9 ng/ml vs. 7.5 +/- 2.1 ng/ml) and vitamin B12 levels (423 +/- 141 pg/ml vs. 356 +/- 121 pg/ml). Plasma homocysteine levels were significantly (p < 0.001) higher in hyperinsulinaemic men than women (11.34 +/- 4.72 mumol/l [n = 38] vs. 7.86 +/- 2.13 mumol/l [n = 53]). There was no significant difference between subgroups classified according to the stages of glucose tolerance in hyperinsulinaemic groups. Plasma homocysteine values exceeding the upper limit of normal range (> 12.45 mumol/l) were detected at a similar prevalence rate in control (4/47 = 8.5%) and in hyperinsulinaemic subjects (10/91 = 10.9%). A weak but statistically significant correlation was found between plasma homocysteine values and age of subjects (r = 0.222; p < 0.05) whereas a stronger correlation was documented between plasma homocysteine and serum creatinine values (r = 0.658; p < 0.001) in hyperinsulinaemic groups (n = 91). Plasma homocysteine values independently from the stages of glucose tolerance are not elevated in hyperinsulinaemic subjects. Hyperhomocysteinaemia is not a characteristic feature of hyperinsulinism suggesting that plasma homocysteine levels are of no considerable importance in the complex pathomechanism of atherosclerosis at early stages of metabolic syndrome.

In Western society, the triad of hypertension, metabolic syndrome and obesity (which caries a high risk for renal disease) is increasing, as is the intake of caffeine. However, no information is available regarding the metabolic or renal consequences of caffeine consumption in this complex disease entity. The purpose of this study was to investigate the effects of chronic caffeine consumption on renal function and metabolic status in obese ZSF1 rats, an animal model of obesity, hypertension and the metabolic syndrome. Fifteen, 18-week-old male, obese ZSF1 rats were randomized to drink tap water (Cont, n = 8) or 0.1% solution of caffeine (Caff, n = 7) for 8 weeks. Metabolic and renal function measurements were performed at baseline and after 4 and 8 weeks of treatment. Caffeine treatment significantly (p < 0.05) reduced body weight, food, and fluid consumption and improved insulin sensitivity (fasting insulin 129.6+/-8.1 vs 97.5+/-3.6 microIU/mL; fed insulin 146.3+/-8.5 vs 110.6+/-3.4 microIU/mL; fasting glucose 138.7+/-13.4 vs 145+/-8.0 mg/dL; fed glucose 373+/-19.4 vs 283.3+/-19.6 mg/dL, Cont vs Caff, respectively). After 8 weeks of caffeine treatment, animals were less glycosuric as compared with control group. Area under glucose curves (AUC-glucose) in oral glucose tolerance test did not differ between the two groups (AUC- glucose: 592.5+/-42.7 vs 589.5+/-20.5 mg/dL x h, Cont vs Caff), whereas caffeine treatment significantly decreased AUC of insulin (AUC-insulin: 257.77+/-12.9 vs 198.0+/-5.9 microIU/mL x h, Cont vs. Caff, p<0.05). No differences were found with regard to plasma triglycerides and glycerol levels; however, caffeine significantly increased cholesterol levels after 4 and 8 weeks (2F-Anova, p<0.001). Moreover, caffeine significantly decreased creatinine clearance after 4 and 8 weeks (CrCl, Cont: 3.5+/-0.4, Caff: 2.2+/-0.2 L/kg/day, p<0.05) and increased protein/CrCl ratio (Cont: 323+/-30, Caff: 527+/-33 mg/L/day). Caffeine treatment for 8 weeks tended to increase plasma norepinephrine levels (p<0.06), but the two groups did not differ with regard to plasma renin activity, blood pressure, renal blood flow or and renal vascular resistance. The study indicates that caffeine improves insulin sensitivity but increases plasma cholesterol levels and impairs renal function in obesity with the metabolic syndrome and hypertension. Our results imply that the health consequences of chronic caffeine consumption may depend heavily on underlying pathophysiology process.
