    Notes: Summary Pancreatic islet cell antibodies and 12 other autoantibodies were measured at the time of diabetes diagnosis in 46 Pima Indians, aged 17–47 years, and in 46 age-sex matched non-diabetic controls. Islet cell antibodies were found in only two diabetics, aged 20 and 25, compared with none of 46 controls. Neither of the subjects with islet cell antibodies had other autoantibodies. At least one type of autoantibody was found in 14 (30%) of the diabetics and in 14 controls, but none was significantly associated] with diabetes. This study indicates that diabetes in the Pima Indians, even those with an onset below 25 years of age, is almost entirely of type II, in that the disease is not associated with islet cell antibodies, ketoacidosis, or insulin dependence.

    Notes: Summary We studied the occurrence of renal disease by measuring serum creatinine and urine protein concentrations in the diabetic members of 316 Pima Indian families with Type 2 (non-insulin-dependent) diabetes in two successive generations to determine if diabetic renal disease aggregates in families. After adjustment for sex and other risk factors, proteinuria occurred among 14.3% of the diabetic offspring if neither parent had proteinuria, 22.9% if at least one diabetic parent had proteinuria, and 45.9% if both parents had diabetes and proteinuria. Among male offspring, an elevated serum creatinine concentration (≥177 μmol/l) was present in 11.7% if the parent had an elevated creatinine and in 1.5% if the parent did not. Thus, proteinuria and high serum creatinine aggregated in diabetic families, suggesting that susceptibility to renal disease is inherited independently of diabetes.

    Notes: Summary The prevalence of abnormal urinary albumin excretion, defined by a urine albumin to creatinine ratio〉-30 mg/g (approximately equivalent to an albumin excretion rate of 〉-30 mg/24 h), was determined in 2728 Pima Indians aged 〉-15 years from the Gila River Indian Community in Arizona, a population with a high prevalence of Type 2 (non-insulin-dependent) diabetes mellitus. Excessive albumin excretion was present in 8% of subjects with normal glucose tolerance, 15% of those with impaired glucose tolerance, and 47% of subjects with diabetes. The intermediate prevalence of abnormal albuminuria in those with impaired glucose tolerance suggests that hyperglycaemia even at levels below those diagnostic of diabetes is associated with renal abnormalities in some subjects and that these abnormalities may precede the onset of diabetes. Abnormal albuminuria at levels not reliably detected by the usual dipstick methods was commonly observed in Pima Indians with diabetes, even those with diabetes of recent onset. Associations were found with age, duration of diabetes, level of glycaemia, blood pressure, and treatment with insulin.

    Notes: Summary To determine if parental hypertension is associated with proteinuria in offspring with non-insulin-dependent diabetes mellitus (NIDDM), 438 diabetic Pima Indians (172 men, 266 women) aged 20 years or more and both of their parents were examined. Hypertension was defined as a systolic blood pressure 140 mm Hg or more, diastolic blood pressure 90 mm Hg or more, or treatment with antihypertensive medicine. Sixty-three percent of the fathers and 80 % of the mothers had diabetes at the time their blood pressure was measured. Families in which either parent had proteinuria, defined as a urine protein-to-creatinine ratio ≥ 0.5 g/g were excluded; 73 (16.7 %) of the offspring had proteinuria. The prevalence rates of proteinuria in the offspring were similar if neither parent or only one parent had hypertension (8.9 and 9.4 %, respectively), but was significantly higher if both parents had hypertension (18.8 %), after adjustment for age, sex, duration of diabetes, and 2-h post-load plasma glucose concentration in the offspring and diabetes in the parents by logistic regression. The odds for proteinuria being present in the offspring if both parents had hypertension was 2.2 times (95 % confidence interval, 1.2 to 4.2) that if only one parent had hypertension. When mean arterial pressure and blood pressure treatment in the offspring were added to the model the relationship remained (odds ratio = 2.2; 95 % confidence interval, 1.1 to 4.3). Hypertension in both parents is associated with the development of proteinuria in offspring with NIDDM. This relationship was present even when controlled for the effects of blood pressure and its treatment in the offspring. [Diabetologia (1996) 39: 433–438]

    Notes: Abstract In 1986, 110,660 of 281,589 residents aged 25–74 years in Da Qing, Hei Long Jiang Province of China, were surveyed. Based on the results of a 75-g oral glucose tolerance test, 630 subjects were found to have previously undiagnosed diabetes according to 1985 WHO criteria. Among them, 600 diabetics aged 35–74 years (288 men, 312 women) and 410 non-diabetics of similar age with normal glucose tolerance (207 men, 203 women) were examined to determine the prevalence of retinopathy and coronary heart disease (CHD) and to evaluate associated characteristics. Retinal examinations of 423 newly diagnosed diabetics showed that 15.5% had several microaneurysms and/or small intraretinal haemorrhage, 5.5% soft exudates, 7.1% hard exudates, and 2.3% proliferative retinopathy. Among 220 non-diabetics, 13.6% had one or two microaneurysms and/or small intraretinal haemorrhage, and only 1.4% had a few soft exudates; half of the non-diabetics with retinopathy had hypertension. CHD, according to Minnesota coding (1.1–1.3, 5.1–5.3 and 7.1) of resting electrocardiograms, was ten times more frequent in the diabetics (3.59%) than in the controls (0.32%), after adjusting for age and sex. Multiple regression analysis showed that plasma glucose concentration analysis showed that plasma glucose concentration was a risk factor for retinopathy after adjusting for age, sex, body mass index (BMI), smoking and blood pressure. Two-hour plasma glucose concentration (after adjusting for age, sex, BMI, smoking and blood pressure) and blood pressure (after adjusting for age, sex BMI, smoking and 1-h or 2-h plasma glucose level) were associated with CHD among the diabetics and non-diabetics and among the diabetics alone. Thus, both micro-and macrovascular complications occur frequently in previously undiagnosed Chinese diabetics and the frequency of CHD is markedly increased compared to the low frequency among Chinese non-diabetics.

    Notes: Abstract A comparative study of hypertension, and indicators of and risk factors for coronary heart disease was undertaken in samples of rural Wallisians of Wallis Island, and first generation Wallisian migrants in the urban centre of Noumea, New Caledonia. Approximately 20% of the adult population of the two communities was included in the study. Higher mean blood pressure and hypertension prevalence in Wallisians in Noumea compared to those in Wallis was documented. There was no significant rise in blood pressure with age in rural Wallisian males. Wallisians in Noumea tended to be more obese than those in Wallis (particularly females). Although differences in the extent of obesity appeared to explain some of the differences in blood pressure between populations of Wallis and Noumea, other environmental factors (such as salt intake) are probably important. There was a trend for a higher prevalence of O wave changes on the ECG in urbanized Wallisians compared to their rural counterparts. There was no significant or consistent differences in plasma lipid concentrations between the two groups. The prevalence of diabetes was 7 and 4 times higher in Noumea compared to Wallis for males and females respectively. Differences in diabetes and hypertension prevalence are more likely to account for the variation in ischaemic heart disease than plasma lipid levels.
