Type 2, non-insulin-dependent diabetes mellitus accounts for 60% of the end-stage renal disease attributed to diabetes in the United States, yet little is known about glomerular function or the development of renal disease in this type of diabetes. The Diabetic Renal Disease Study (DRDS) is a longitudinal study designed to elucidate the natural history of renal disease and to characterize glomerular function throughout the course of renal disease in type 2, non-insulin-dependent diabetes mellitus. The study is being conducted among the Pima Indians from the Gila River Indian Community in Arizona because they experience a very high rate of type 2 diabetes mellitus, which often develops at a young age and which is frequently associated with the development of renal disease. Glomerular filtration rate, renal plasma flow, albumin and IgG excretion, level of vasoactive hormones, retinal damage, and glomerular capillary permeability to dextrans of different sizes will be assessed at regular intervals over 48 months in six groups of subjects representing a range of glucose tolerance from normal to diabetes, and among the diabetic subjects, a range of proteinuria from normal to overt diabetic nephropathy. The DRDS is designed to provide new information on the functional determinants of renal disease in type 2, non-insulin-dependent diabetes mellitus and will serve as the basis for designing intervention strategies.

Renal failure among elderly individuals with diabetes is a substantial clinical and public health problem. These individuals account for the majority of renal failure among people with diabetes mellitus in the United States. Although limited population-based data directly provide evidence regarding the incidence of and risk factors for ESRD, extant data suggest that blacks and Pima Indians have a markedly increased risk of ESRD compared with whites in the United States. Proteinuria and microalbuminuria appear to be extremely common in elderly individuals with NIDDM and are strongly associated with overall survival, cardiovascular morbidity and mortality, and the development of ESRD. Although randomized clinical trials are needed to test intervention strategies to reduce morbidity and mortality associated with renal disease among individuals with NIDDM, extant data suggest that management efforts directed at hypertension control and, possibly, moderate restriction of protein intake may be important therapeutic modalities for prevention of renal disease and its associated sequelae among elderly individuals with diabetes.

The incidence of fatal coronary heart disease (CHD) was determined in a population of Pima Indians from the Gila River Indian Community in Arizona. Between 1975 and 1984, 394 deaths occurred among 4,828 subjects aged 5 years or older, and 199 of these occurred in the 1,093 persons with non-insulin-dependent diabetes. Only 28 deaths were attributed to CHD; all occurred among the 689 diabetic persons 45 years of age or older. No CHD deaths occurred among the 419 nondiabetic subjects 45 years of age or older. The rate of fatal CHD among the diabetic subjects was higher in men than in women and increased with advancing age and duration of diabetes. A higher incidence of fatal CHD was associated with proteinuria, renal insufficiency, medial arterial calcification, diabetic retinopathy, insulin therapy, and an abnormal electrocardiogram. In Pima Indians aged 50-79 years, the incidence of fatal CHD was less than half that found in the Framingham population after controlling for age, sex, and diabetes (incidence rate ratio, 0.4; 95% confidence interval, 0.2-0.7). Factors protecting Pima Indians from fatal CHD may include racial heritage, low serum concentrations of total and low density lipoprotein cholesterol, and rarity of heavy smoking. Among the diabetic subjects, mortality from diabetic renal disease, which shows many of the same risk factors, may selectively compete and remove those at risk for fatal CHD. This would not, however, explain the lack of fatal CHD among the nondiabetic subjects. Fatal CHD shares many of the risk factors associated with the specific microvascular complications of diabetes, and diabetes and its associated attributes are the major predictors of fatal CHD in this population.

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 (greater than or equal to 177 mumol/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.

Diabetic renal disease is a major source of morbidity and mortality in Pima Indians. Excess mortality in NIDDM occurs principally in those with proteinuria regardless of whether death is due to cardiovascular or renal disease. Diabetes duration is a strong predictor of diabetic renal disease. Additional predictors include blood pressure, severity of diabetes, and, most likely, genetic or shared environmental determinants. The incidence rate of diabetic renal disease in Pima Indians with NIDDM is similar to that reported for subjects with IDDM with equivalent durations of diabetes. These observations suggest that clinical proteinuria and renal failure may occur in patients with NIDDM just as frequently as in those with IDDM. This finding has important implications and suggests that the variations in the frequency and age of onset of NIDDM among different populations and ethnic groups may be primarily responsible for the apparent variations in the frequency of ESRD associated with diabetes in different populations. Furthermore, diabetic renal disease appears to account for virtually all of the excess mortality associated with diabetes among Pima Indians and may perhaps do so in other populations. Improved survival of persons with NIDDM, an increasing incidence of this disease, and a relatively early age of onset in many populations could lead to a dramatic increase in the incidence of ESRD in the future. On the other hand, if diabetic renal disease and its consequences could be prevented, a profound improvement in the longevity and quality of life of those afflicted with diabetes might be possible.

Little is known of the natural history of nephropathy in type 2 (non-insulin-dependent) diabetes, yet type 2 diabetes is a major cause of end-stage renal disease in the United States. The incidence rate of heavy proteinuria was determined in Pima Indians participating in a longitudinal population study of diabetes and its complications. Heavy proteinuria was defined by a urine protein (g/liter) to urine creatinine (g/liter) ratio greater than or equal to 1.0 (greater than or equal to 113 mg protein/nmol creatinine), a level which corresponds to a urine protein excretion rate of about 1 g/day. The incidence rates of proteinuria in diabetic Pimas were 4, 12, 37, and 106 cases/1,000 person-years at risk in the periods 0 to 5, 5 to 10, 10 to 15, and 15 to 20 years after the diagnosis of diabetes. The cumulative incidence rates were 2%, 8%, 23%, and 50% at 5, 10, 15, and 20 years, respectively. The duration of diabetes, severity of diabetes as determined by the degree of hyperglycemia and type of treatment, and blood pressure were risk factors for proteinuria. The presence of heavy proteinuria was strongly associated with the development of renal insufficiency, defined by serum creatinine greater than or equal to 2.0 mg/dl (greater than or equal to 177 mumol/liter). The incidence of proteinuria in type 2 diabetes in Pima Indians was as high as that reported in type 1 diabetes in other populations and represents a frequent, serious complication of the disease.

The incidence of proliferative diabetic retinopathy was determined in the Pima Indians of the Gila River Indian Community in Arizona. Over 4 yr, this complication developed in 25 of 953 subjects greater than or equal to 9 yr of age with non-insulin-dependent diabetes. No cases were diagnosed in less than 35-yr-old subjects, and the incidence was strongly related to the duration of diabetes. The cumulative incidence of proliferative retinopathy after 20 yr duration was 14%. All cases of proliferative retinopathy occurred in subjects with background retinopathy. Younger age at diagnosis of diabetes was associated with a higher incidence of proliferation when subjects with diabetes of similar duration were compared. A higher incidence of proliferative retinopathy, after controlling for age, sex, and diabetes duration, was associated with hypertension, proteinuria, renal insufficiency, absence of Achilles tendon reflex, elevated total serum cholesterol concentration, and insulin therapy.

The effect of proteinuria (greater than or equal to approximately 1 g/day) on mortality in non-insulin-dependent diabetes mellitus (NIDDM) was assessed in Pima Indians aged greater than or equal to 45 yr. Among 1426 subjects, 48% with NIDDM at the beginning of followup, there were 489 deaths in 13,345 person-yr of observation. The age- and sex-adjusted mortality rate was 32.7/1000 person-yr (95% Cl = 27.6, 37.8) in diabetic subjects without proteinuria, similar to the rate of 30.1/1000 person-yr (95% Cl = 25.7, 34.4) in nondiabetic subjects without proteinuria. By contrast, in diabetic subjects with proteinuria the mortality rate was 121.4/1000 person-yr (95% Cl = 97.5, 145.3). When controlled for age, sex, and diabetes duration, diabetic subjects with proteinuria had a death rate 3.5 times as high (95% Cl = 2.8, 4.4) as those without proteinuria. Of the excess mortality associated with NIDDM in Pima Indians, 97% was found in subjects with proteinuria. The death rate in diabetic subjects without proteinuria was not appreciably greater than the rate in nondiabetic subjects. Mortality rates from uremia and cardiovascular disease were significantly higher in diabetic Pima Indians with proteinuria than in those without. These relationships are similar to observations reported in people with insulin-dependent diabetes.

Medical arterial calcification was studied among 4,553 subjects in a 20-year, longitudinal study of Pima Indians. The prevalence and incidence of medial arterial calcification were highest among men, the elderly, and patients with Type 2 (non-insulin-dependent) diabetes mellitus. Medial arterial calcification was most commonly observed in the feet and appeared to progress proximally. Proportional hazards analysis was used to evaluate risk factors for medial arterial calcification in the feet and to evaluate medial arterial calcification as a risk factor for death and for complications of diabetes. Among diabetic patients, risk factors for medial arterial calcification were impaired vibration perception, long duration of diabetes, and high plasma glucose concentration (p less than 0.01 for each). Among nondiabetic subjects, age, male gender (p less than 0.01 for each), and high serum cholesterol concentration (p = 0.02) were risk factors for medial arterial calcification. Nondiabetic subjects with medial arterial calcification did not have higher mortality rates than subjects without medial arterial calcification (rate ratio = 0.95, 95% confidence interval = 0.7-1.3). Diabetic patients with medial arterial calcification, compared with diabetic patients without medial arterial calcification, had 1.5-fold the mortality rate (95% confidence interval = 1.0-2.1), 5.5-fold the rate of amputations (95% confidence interval = 2.1-14.1), 2.4-fold the rate of proteinuria (95% confidence interval = 1.3-4.5), 1.7-fold the rate of retinopathy (95% confidence interval = 0.98-2.8), and 1.6-fold the rate of coronary artery disease (95% confidence interval = 0.48-5.4).

The risks of microvascular complications over periods of 3 and 6 years in relation to baseline plasma glucose concentrations were estimated in Pima Indians of Arizona aged 25 years or more and who were not taking hypoglycaemic medicine at their initial examinations. Retinopathy (microaneurysms, haemorrhages, or neovascularisation) developed within 3 years in 1% of 181 subjects with initial fasting plasma glucose concentrations less than 140 mg/dl (1 mg/dl = 0.0555 mmol/l) and in 13% of 39 subjects with higher initial fasting plasma glucose levels. No one with an initial 2 h glucose concentration less than 200 mg/dl had retinopathy within 3 years, but the rate was 12% in 60 subjects with higher glucose concentrations. Retinopathy developed within 6 years in 1% of 446 subjects whose 2 h post-load glucose concentrations were less than 200 mg/dl and in 20% of 113 subjects with higher levels. Subsequent development of heavy proteinuria (urine protein/creatinine ratio at least 1.0) was less common than that of retinopathy, but was similarly related to the initial fasting and 2 h plasma glucose concentrations. The finding that these microvascular complications rarely appeared in individuals with fasting plasma glucose concentrations less than 140 mg/dl or 2 h plasma glucose concentrations less than 200 mg/dl supports the validity of these concentrations as part of the new diagnostic criteria for diabetes mellitus.
