As part of an on-going longitudinal study, 7895 men of Japanese ancestry living on the island of Oahu, aged 45-68 and free of evidence of prior stroke at entry examination, have been followed by re-examinations and surveillance. During ten years of follow-up 154 men developed thromboembolic stroke, 65 developed intracranial hemorrhage, and 19 developed stroke of unknown type. There were 79 deaths attributed to stroke. The independent risk factors for thrombo-embolic stroke were elevated blood pressure, glucose intolerance, age, electrocardiographic evidence of left ventricular hypertrophy or strain, cigarette smoking and proteinuria. Attributes associated with increased risk of intracranial hemorrhage were age, elevated blood pressure, cigarette smoking, serum uric acid and, inversely, serum cholesterol level. Electrocardiographic evidence of left ventricular hypertrophy or strain significantly increased the risk of cerebral hemorrhage, but was not associated with subarachnoid hemorrhage. In univariate analysis, there was an inverse relation between dietary fat intake and thrombo-embolic and total stroke incidence. An inverse relation was also shown between protein intake and total stroke incidence. These dietary relations became statistically not significant in multivariate analysis. No relation was found between salt intake and the incidence of stroke.

To determine whether sustained control of hyperglycaemia in Type 2 (non-insulin-dependent) diabetic patients would diminish proteinuria, the effect of hypocaloric diet therapy (500 kcal/day) on proteinuria was assessed in obese, Type 2 diabetic patients (n = 24) and compared with results obtained for obese subjects with normal glucose tolerance (n = 7) and impaired glucose tolerance (n = 6). Diet therapy of similar mean duration resulted in similar percentage weight loss (mean percentage of original weight +/- SEM) in diabetic (13.6 +/- 1.6%), glucose intolerant (16.4 +/- 3.3%) and obese non-diabetic (11.0 +/- 1.0%) subjects. Following therapy, plasma glucose concentrations 2h after an oral glucose load declined in the diabetic (18.34 +/- 0.81 to 10.67 +/- 0.50 mmol/l, mean +/- SEM; p less than 0.001) and in the glucose intolerant subjects (10.2 +/- 0.3 to 7.3 +/- 0.4 mmol/l, p less than 0.01) while remaining unchanged in the obese non-diabetic subjects (7.09 +/- 0.23 to 6.77 +/- 0.32 mmol/l, NS). Concentrations of total protein of plasma origin and albumin in 24-h urine collections were quantified by a sensitive immunonephelometric assay using specific antisera. Initially, 24-h excretion of total protein and albumin were elevated in the diabetic [mg protein/24 h; (median +/- 95% confidence limits): 63 (42-138), p less than 0.05; albumin: 26 (14-56), p less than 0.05] and glucose intolerant subjects [protein: 52 (13-92), NS; albumin: 24 (3-61), NS] compared with the non-diabetic subjects [protein: 20 (5-38); albumin: 6.2 (3.5-9.5)].(ABSTRACT TRUNCATED AT 250 WORDS)

Studies were conducted to assess the renal functional state in two recently discovered diabetic chimpanzees. Both were nonobese, adult female animals with the non-insulin-dependent form of impaired glucose tolerance, analogous to the Type II or nonobese, maturity-onset diabetes of humans. Both animals displayed moderate-to-heavy proteinuria and glycosuria in response to intravenous administration of glucose or tolbutamide. Chimpanzee number 333, but not number 1037, had fasting proteinuria and chronic hypertension. Renal function studies, using the inulin clearance method, demonstrated significantly decreased glomerular filtration rates and elevated rates of sodium excretion for both animals. The rate of chloride excretion was also elevated in animal number 1037, but potassium excretion was apparently unaffected in both animals. Abnormal serum biochemical parameters demonstrated for chimpanzee number 333 included elevations in calcium, magnesium, creatinine, urea nitrogen, and uric acid; animal number 1037 had only an elevated serum creatinine. Results are consistent with the occurrence of renal disease similar to the nephropathy that develops in human diabetics. The difference in severity of renal impairment in the two chimpanzees is possibly related to differences in duration and severity of impaired glucose tolerance. A progression of both diabetic and renal disorders is most probable.

The Strong Heart Study, a study of cardiovascular disease among American Indians, was conducted to determine cardiovascular disease rates and the prevalence of risk factors among members of 13 tribal groups in South Dakota/North Dakota (SD/ND), southeastern Oklahoma, and Arizona. From 1989 to 1992, 4,549 tribal members aged 45-74 years (62% of eligible participants) were surveyed and examined for cardiovascular disease and its risk factors. Mean total cholesterol concentrations were over 20 mg/dl lower among the men and 27 mg/dl lower among the women than national mean levels for the same age groups. Cholesterol levels varied by tribal group; Arizona Indians had mean levels more than 20 mg/dl lower than those of SD/ND Indians. The prevalence of hypercholesterolemia was almost twice as high among SD/ND Indians as among Arizona Indians, but the rates for all three groups were much lower than total US rates (all races). Mean levels of high density lipoprotein cholesterol were lower among Indian men and women than in the US population as a whole. The prevalence of hypertension among Arizona and Oklahoma Indians was higher than that for the entire United States. SD/ND Indians had significantly lower mean blood pressures and prevalence rates of hypertension than Oklahoma and Arizona Indians and the United States as a whole. The prevalence of cigarette smoking was higher for all Indian groups except Arizona women in comparison with US rates. Smoking rates were highest in SD/ND and lowest in Arizona. Indian smokers smoked fewer cigarettes per day than the average US smoker. Arizona Indians had the highest prevalence of diabetes mellitus; over 60% of those participants were diabetic. In Oklahoma and SD/ND, one third of the men and over 40% of the women were diabetic. In addition, 13-20% of the participants had impaired glucose tolerance. Proteinuria was also a common problem; almost half of the Arizona Indians had micro- or macroalbuminuria, and 20% of Oklahoma and SD/ND Indians had significant proteinuria. The prevalence of obesity was high in all three groups, with Arizona Indians having the highest rates and the highest mean body mass indices. The prevalence of current alcohol use was lower among Indians than in the nation as a whole, but binge drinking was common among those who used alcohol. These results indicate that cardiovascular disease risk factors vary significantly among tribal groups. Prevention programs tailored toward decreasing the prevalence of risk factors are recommended for long-term reduction of cardiovascular disease rates in American Indian communities.

We studied 318 subjects aged 80 years of over included in the Cardiovascular Study in the Elderly (CASTEL). Some well known risk factors (left ventricular hypertrophy, glucose intolerance, cholesterol, ApoB/ApoA ratio, triglycerides, proteinuria, cigarette smoking, and ECG abnormalities), whose importance in cardiovascular risk is definitely accepted for young adults, were very poor predictors of mortality in our survey. On the contrary, FEV1 reduction and blood uric acid were strong predictors.

Twenty-one patients with membranous nephropathy, heavy proteinuria and progressive renal failure were treated with alternating monthly cycles of corticosteroids and chlorambucil for six months. Four patients received repeat courses. After a median period of follow-up of 39 months, three patients had died, six were receiving renal replacement therapy or had serum creatinine > 500 mumol/l, and one had progressive renal failure. Eleven patients had either stable or improved renal function, as judged by serum creatinine concentration. Of these eleven, four patients were in partial remission (daily protein excretion 0.2-2.0 g), and two were in complete remission. There was a tendency for those who received intravenous methylprednisolone to have a more favourable outcome. There was a high incidence of side-effects, with significant complications related to drug therapy observed in > 50% of subjects. Although individual patients appeared to respond well, sometimes dramatically, these results are less encouraging than other reports. We would urge caution in the use of this form of therapy, particularly in older patients who may have occult neoplasms, impaired glucose intolerance or pre-existing cardiac disease.

Cerebrovascular and cardiovascular diseases are important predictors for survival in patients undergoing continuous ambulatory peritoneal dialysis (CAPD), and account for about half the deaths in these patients. Lipoprotein(a) [Lp(a)] is known to show high values in diabetics with proteinuria, and albuminuric renal disease. The purpose of this study was to determine Lp(a) levels and to investigate the association of Lp(a) and atherosclerotic risk factors in patients treated by CAPD. Lp(a) concentration were measured in 20 CAPD patients in the age range 31 to 83 years. Mean (+/- SD) levels of serum Lp(a) were elevated in the CAPD patients compared to age, sex matched 17 controls (49.5 +/- 27.7 vs. 15.5 +/- 12.4 mg/dl, p < 0.001). The levels of Lp(a) were significantly higher in the diabetic CAPD patients than in non-diabetics. There were significant positive correlations between serum Lp(a) concentrations and fasting blood sugar. However, when the above two groups were matched for age, sex, body mass index and FBS, Lp(a) concentrations were also significantly higher in CAPD patients than those in normal controls. We found no statistically significant correlations of Lp(a) with either age, body mass index, blood pressure, serum lipoprotein, apoprotein, glycated hemoglobin, BUN, creatinine or serum protein levels. There were no correlations between serum Lp(a) levels and albumin and LP(a) concentrations in the dialysate in all CAPD patients. Along with assessment of other known established cardiovascular risk factors such as elevated blood pressure, atherogenic abnormalities of plasma lipids and lipoproteins, and impaired glucose tolerance, we suggest that elevated levels of Lp(a) may lead to the accelerated atherosclerosis in these patients.

The 50 g oral glucose challenge test (50gGCT) was performed on 622 pregnant women, and 75 g oral glucose tolerance test (75gGTT) was further done on subjects with screening tests value of > or = 7.78 mmol/L. The results showed that there were 16.56% (103/622) women with screening value of > or = 7.78 mmol/L, among whom, 32 were identified as having gestational impaired glucose tolerance (GIGT) and 12, gestational diabetes mellitus (GDM) by confirmatory test of 75gGTT. The sensitivity of 50gGCT was 42.72%(44/103). The incidences of edema-proteinuria-hypertension syndrome (EPH-syndrome), premature rupture of membranes, fetal macrosomia, operative deliveries and perinatal morbidity were higher in women with GIGT/GDM than in women without GIGT/GDM. It suggests that 50gGCT is an ideal method of screening for GDM and should be performed on all pregnant women.

An increased albumin excretion rate (AER) is associated with impaired glucose tolerance and diabetes mellitus in some populations, but data on Americans of Northern European origin are lacking. In 1986-1987, AER and creatinine clearance were measured in 455 adults in a survey of the population of Wadena, Minnesota. Thirty-five subjects (8%) had an AER > or = 15 micrograms/minute, and eight of these had overt proteinuria (AER > or = 175 micrograms/minute). AER and creatinine clearance were uncorrelated except when AER was increased. Unadjusted mean AER in a stratified random sample of adults (n = 374) was 3.6 micrograms/minute. Adjusted values for 277 subjects with normal glucose tolerance and for 80 subjects with impaired glucose tolerance were very similar (3.8 and 3.7 micrograms/minute, respectively), whereas mean AER was 5.4 micrograms/minute for persons with non-insulin-dependent diabetes mellitus (NIDDM) who were not taking insulin and 9.4 micrograms/minute for persons with NIDDM who were taking insulin (p < 0.0001). After adjustment for age, mean creatinine clearance was unrelated to glucose tolerance. Systolic blood pressure was a major determinant of increased AER (p < 0.0001) and lowered creatinine clearance (p = 0.0011), independently of diabetes. AER was stable over 5 years among the 321 cases who were not taking insulin and were not severely hypertensive. The decrease in creatinine clearance was greater in ex-smokers and current smokers than in nonsmokers. The authors conclude that hypertension and NIDDM were independently associated with the risk of kidney damage in this population, as indicated by a higher AER. High-normal blood pressure, but not impaired glucose tolerance, was associated with microalbuminuria. These relatively mild changes may reflect an ethnically based resistance to the damaging effects of hyperglycemia on the kidney. Smoking may accelerate the aging-related decline in glomerular filtration rate.

This study evaluated the role of impaired glucose tolerance (IGT) as a risk factor in a general population of 2079 non-diabetic elderly subjects. The 10-year cardiovascular morbidity was similar in normal and IGT subjects. Mortality was greater in IGT, but the Cox equations of the hazard rate were different in younger and older subjects: age, sex, lung function (forced expiratory volume in 1 s, FEV1), serum uric acid, IGT and proteinuria were predictors of overall mortality in the age class 65-79 years, while only the first 4 were associated with cardiovascular mortality. The same four items also predicted overall survival in subjects over 79 years old, while only age and uric acid were predictors of cardiovascular mortality. In older subjects, total cholesterol showed an inverse predictive value. Hyperuricaemia (> 6.4 mg/dl) and proteinuria did predict mortality in normal but not in IGT subjects, while reduced FEV1 (< 60% theoretical) was predictive in all. In 65-79-year old subjects IGT predicted mortality provided that FEV1 was normal, while in those 380 years old IGT was not a predictor. These interrelationships should be taken into account to better understand the factors underlying mortality.
