High-performance liquid chromatographic (HPLC) analysis of human serum albumin (HSA) on Asahipak GS-520H columns at neutral pH (6.87) showed a clear resolution of human mercaptalbumin (HMA) and nonmercaptalbumin (HNA), which are reduced and oxidized form of HSA, respectively. We studied the conversion of HMA to HNA (mercapt-nonmercapt conversion) as an index of oxidative change of the tissues and organs in 28 normal subjects and in a total of 47 patients with non-insulin dependent diabetes mellitus (NIDDM). Mean (+/- SD) values of the HMA fraction of HSA, f(HMA), [HMA/(HMA + HNA)], was significantly lower in NIDDM patients than in normal subjects (0.63 +/- 0.067 vs 0.75 +/- 0.028, P < 0.001). It was lower in poorly controlled NIDDM patients (0.63 +/- 0.058, n = 20) than in well controlled NIDDM patients (0.67 +/- 0.032, n = 9) (P < 0.05). Plasma glucose values sampled on occasions including overnight fasting and postprandial ones (r = -0.441, n = 47, P < 0.01), but not plasma glucose values sampled on overnight fasting (r = -0.345, n = 29) or postprandial (r = -0.467, n = 18) conditions and HbA1c (r = -0.211, n = 34), negatively correlated with the f(HMA) values, indicating that mercapt-nonmercapt conversion may not be due to cumulative hyperglycemia over a month, but due to short-term alteration in blood glucose level. The presence or absence of diabetic complications including nephropathy, retinopathy and neuropathy did not affect the f(HMA) values. In conclusion, decreased f(HMA) values in the diabetic patients suggested the presence of a rapidly altered oxidative change of albumin due to hyperglycemia.

According to international consensus, microalbuminuria is defined as an elevated urinary albumin excretion rate (UAER) of 20-200 micrograms/min, which is below the proteinuric range. Nephropathy is a major complication in IDDM, seen in about 30% of patients after many years of diabetes. Increasing microalbuminuria is an excellent marker of subsequent nephropathy in these patients. End-stage diabetic nephropathy is also important in NIDDM, but in most Western countries this serious complication eventually develops in only 5 to 10% of cases, whereas the majority of patients die before this from cardiovascular disease. In completely healthy individuals there is no clear correlation between age and UAER, at least up to about 70 years of age. The mean excretion rate is around 5 micrograms/min, with a considerable range, but excretion only rarely exceeds 15 micrograms/min. In population studies among middle-aged and elderly individuals, higher values are seen. In newly diagnosed NIDDM about 40% of patients show an excretion rate above 15-20 micrograms/min. There is a significant but not precise correlation between albumin excretion rate and glycemic control, and usually UAER is reduced by standard antidiabetic treatment. In a considerable number of patients, high values cannot be reduced. In the course of NIDDM about 20-30% of patients show microalbuminuria. In patients with known diabetes, microalbuminuria is related not only to subsequent diabetic proteinuria, but even more strongly to early death, mainly from cardiovascular disease. Even slight microalbuminuria (15-40 mg/l in early morning urines) is clearly associated with increased mortality. In subjects with newly detected elevated blood glucose (by screening) microalbuminuria also predicts early mortality. The mechanisms are not established, but several arteriosclerosis-related risk factors are seen more frequently in patients with microalbuminuria, e.g. lipid abnormalities, elevated systolic blood pressure (BP), hemostatic measures, as well other markers of cardiovascular disease. Usually there is a significant but not precise correlation between BP and UAER in groups of patients throughout the course of diabetes. New studies document that also in the elderly background population microalbuminuria is a significant risk factor for early death, maybe even stronger than the established risk markers, which thus may be confounded with the presence of microalbuminuria.

We prospectively conducted a hospital based study to determine the prevalence of vascular complications in NIDDM and their risk factors. Using standard protocol for interviewing, physical examination and laboratory investigations, we studied 207 patients from the diabetic clinic and medical outpatient department (ratio 3.9:1) by systematic sampling. The prevalence of hypertension, coronary heart disease cerebrovascular disease, peripheral and large vessel disease was 22.2, 22.2, 8.2, 21.3 and 34.8 per cent respectively. We found that the prevalence of small vessel disease, retinopathy and nephropathy was 34.3, 25.1 and 12.5 per cent respectively. The complications were slightly higher in females and increased with duration of diabetes. By univariate and logistic regression analysis, we found that the risk factors of large vessel disease were body mass index, diastolic blood pressure, duration of diabetes and for small vessel disease were duration of diabetes and high uric acid.

Points of agreement: (1) In IDDM, hypertension occurs in patients who have already developed nephropathy, probably in the microalbuminuric phase. (2) Hypertension is an important accelerator of the development of diabetic nephropathy. (3) Hypertension, obesity and NIDDM are often associated, and insulin resistance is commonly observed in all three states. (4) Antihypertensive therapy retards the development of diabetic nephropathy in IDDM and reduces proteinuria in NIDDM. (5) The choice of antihypertensive agent in the diabetic patient must be based upon the efficacy of the drug as well as avoidance of side effects including deleterious influence on glucose, insulin and lipid levels and renoprotection. (6) Carefully conducted long-term comparative trials between different classes of antihypertensive drugs in microalbuminuric IDDM and NIDDM patients are essential. Points of major controversy: (1) Detection of IDDM patients prone to the development of diabetic nephropathy can be performed by measuring specific parameters such as erythrocyte Na(+)-Li+ countertransport activity. (2) Insulin resistance is a pathogenic mechanism rather than purely an association with hypertension and obesity. (3) A certain class of antihypertensive agents--ACE inhibitors--confers a specific renoprotective effect in diabetic nephropathy, in addition to its effects upon systemic blood pressure. (4) Reduction of blood pressure should be considered in the normotensive microalbuminuric diabetic patient. (5) Microalbuminuria is a sufficient 'surrogate endpoint' for the progression of renal failure.

We designed this study to elucidate a possible involvement of genetic factors which influence the progression of renal dysfunction in patients with non-insulin dependent diabetes mellitus (NIDDM). A total of 328 patients was randomly selected in the Tokai University Hospital. They had been cared for in our hospital as NIDDM for the past five years, until April, 1989. Fifty-six patients with persistent albuminuria, and an equal number of patients without persistent albuminuria were included in this study. No significant differences were observed between the two groups in terms of age, estimated period of illness, blood pressure, body-mass index, HbAlc, blood glucose, total cholesterol, triglyceride level and mean blood pressure. The family histories obtained by questionnaires revealed that there might be some genetic predisposing factors leading to the onset of nephropathy in patients with NIDDM, especially in cases with paternal high blood pressure. It is suggested that paternal hypertension might be related to the development of nephropathy in patients with NIDDM.

Not all patients with diabetes develop clinically significant nephropathy and, for this reason, attention has begun to focus on the risk factors for development of this serious complication. These risk factors have not been quantified to the same degree as those factors associated with more common progressive vascular diseases, such as atherosclerosis. However, studies of pathogenesis and clinical and epidemiological surveys of diabetic nephropathy point to numerous risk categories. Glycemic control, genetic and familial predispositions, renal and glomerular enlargement, glomerular hyperfiltration, and capillary and systemic hypertension can be invoked as contributors to this disease process. This review focuses on hemodynamic alterations and their role in the development and progression of diabetic nephropathy. Increases in GFR, largely driven by increases in plasma flow and capillary pressure, appear in early IDDM and NIDDM. This abnormality of renal vascular control probably is derived from alterations in several vasoactive control systems. In addition, the elevations in capillary pressure may be damaging to the glomerular capillaries. Arterial hypertension is not necessarily present before clinical nephropathy appears; however, it is a usual concomitant of progressive diabetic renal disease. The strongest evidences for the roles of altered systemic and renal hemodynamics in the progression of diabetic renal disease are clinical and experimental studies demonstrating attenuation of the disease process by lowering systemic and capillary pressures with antihypertensive agents, and dietary and glycemic modifications. Thus, although multiple factors probably interact to determine risk for the development of diabetic nephropathy, hemodynamic forces are a particularly important contributor and are especially amenable to therapeutic intervention.

Diabetes mellitus is a disease with major long-term implications, not only for the health and well-being of affected individuals, but also for costs to the National Health Service. Treatment of the disease and its complications takes up 4-5% of total health care expenditure in the U.K. These costs are dominated by in-patient care for the complications arising from diabetes. This paper presents a review of studies which have been carried out on the costs of diabetes and its complications. For such a chronic and potentially disabling disease with numerous complications it is surprising that costs have not been more extensively researched. A large amount of data are available about the implications of diabetes in terms of incidence and prevalence, but few costs have been collected, particularly indirect and marginal costs. Both insulin dependent (IDDM) and non-insulin dependent (NIDDM) diabetic patients exhibit similar complications so that the cost of treatment may be comparable, but further studies are needed to establish this. In addition, few studies have included diabetes as a secondary diagnosis. The studies which are available have tended to focus on direct costs, for example, the costs of hospital care, consultations and drugs, because they are the easiest to measure. Fewer studies have included indirect costs, such as the effect of time lost from work, early retirement and premature death, because of the difficulties in assigning monetary values to these factors. The most important contributors to the costs of diabetes are those of treating complications such as eye and limb disease, heart disease, neuropathy and nephropathy.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors investigated the incidence of different disorders of the lipid metabolism and their age dependence in a group of 67 patients with type 2 diabetes hospitalized at the First Medical Clinic in Kosice. Some disorder of the lipid metabolism was recorded in 67% of the patients. The most frequently encountered disorder was hypertriglyceridaemia (21%). Hypercholesterolaemia was recorded in 16%, combined hyperlipidaemia in 18% and hypoalphalipoproteinaemia in 12% of the patients. Patients with diabetic nephropathy had significantly elevated mean triglyceride levels and reduced HDL-cholesterol levels, as compared with patients without nephropathy. In diabetic women a significantly higher incidence of combined hyperlipidaemias was recorded, as compared with men and the mean total cholesterol and triglyceride levels were also significantly higher in women with type 2 diabetes.

Hypertension is a very frequent condition in individuals with non-insulin dependent diabetes mellitus (NIDDM) in Japan and has affected the occurrence of late diabetic complications, especially stroke and nephropathy. Despite similar characteristics of hypertension among Japanese and white patients, the effect of hypertension on the development of coronary artery disease (CAD) in these two populations is strikingly different. In white NIDDM patients, hypertension is one of the major risk factors for the development of CAD. However, CAD is an infrequent complication in NIDDM patients in Japan, even though they have hypertension, lipid abnormalities, and renal complications.

Non-insulin-dependent diabetes mellitus is epidemic among African-American women in the United States; reports of its prevalence among African Americans range from 50% to 60% higher than among whites. African Americans also incur higher rates of diabetes-related complications such as blindness, end-stage renal disease, and amputations. Data indicate that non-insulin-dependent diabetes among African Americans is associated with lower socioeconomic status and with obesity. Because obesity has been hypothesized as contributing to the growing numbers of non-insulin-dependent diabetics among African-American women, new strategies are urgently needed to promote weight loss in this population. Community organization can broaden health education and facilitate behavior change toward development of life- and self-mastery skills. Specific strategies of this approach include (1) integrating community values into health messages, (2) facilitating neighborhood "ownership" and decision-making, (3) utilizing existing formal and informal networks, and (4) empowering individuals and community. Community organization may be a promising strategy among low-income minority communities to reduce the risk of non-insulin-dependent diabetes by promoting changes in dietary patterns, because it ensures that the health messages and programs that emerge will be consistent with existing sociocultural norms and beliefs.
