Of the various types of diabetes mellitus, non-insulin-dependent diabetes (NIDDM) is by far the most common and is increasing rapidly in many populations around the world. It is a heterogeneous disorder, characterized by a genetic predisposition and interaction between insulin resistance and decreased pancreatic beta-cell function. There is a strong association between the presence of obesity and low levels of physical exercise and the development of NIDDM. However, NIDDM may also develop in lean individuals and the incidence increases significantly with increasing age. A diagnosis of impaired glucose tolerance or gestational diabetes is a strong predictor for future development of NIDDM and should signal appropriate interventions to prevent or delay the progression to NIDDM. NIDDM is frequently associated with other conditions such as hypertension, hypertriglyceridemia and decreased high-density lipoprotein which are additional risk factors for atherosclerosis and cardiovascular disease. The 'insulin resistance syndrome', which includes obesity, NIDDM, hypertension, hyperinsulinemia and dyslipidemia is a major and increasing cause of morbidity and mortality in many populations. In addition, people with NIDDM and poor glycemic control may develop severe microvascular complications of diabetes, including retinopathy, nephropathy and neuropathy. Appropriate diet, weight control and increased physical activity will increase insulin sensitivity in insulin resistant patients and are effective treatments for patients with NIDDM or may prevent the development of NIDDM in susceptible individuals. If these measures are unsuccessful, then oral hypoglycemic agents or insulin therapy may be required.(ABSTRACT TRUNCATED AT 250 WORDS)

Dyslipidemia accompanies end-stage renal disease (ESRD) and contributes to the high incidence of cardiovascular disease in patients on chronic dialysis treatment. The lipid abnormalities of elevated triglyceride level and reduced high-density lipoprotein cholesterol level that occur in ESRD are associated in the normal population with an altered distribution of low-density lipoprotein (LDL) particle size, a pattern associated with increased risk of coronary heart disease. To assess the effect of ESRD on LDL particle size distribution, we examined plasma lipid levels and LDL particle size in 43 subjects on chronic hemodialysis, 23 subjects on continuous ambulatory peritoneal dialysis, and 30 control subjects with normal renal function. Of subjects on continuous ambulatory peritoneal dialysis, 48% had small LDL particle size compared with 23% of subjects on hemodialysis and 7% of control subjects. Subjects on both forms of dialysis also had higher triglyceride levels and lower high-density lipoprotein cholesterol levels that correlated with LDL particle size. We conclude that altered LDL particle size forms an important component of the metabolic abnormalities that contribute to the increased cardiovascular risk found in ESRD.

We retrospectively analyzed the courses of 37 non-insulin dependent diabetics (hemodialyzed:HD group) with end-stage renal disease (ESRD), to identify factors predisposing to renal failure. The factors analyzed were: diabetic (non-proliferative and proliferative) retinopathy, family histories of diabetes and hypertension, smoking, dyslipidemia, first examination proteinuria and non-compliance. These factors were statistically compared in 37 NIDDM without renal failure (non-HD group). There were no significant differences in age or duration of diabetes between the two groups. Significant differences (P < 0.001) were, however, recognized in diabetic proliferative retinopathy and hypertension between the two groups. Hypertension was present in 35/36 (97.2%) HD patients and in 21/36 (58.3%) non-HD patients. A family history of hypertension was recognized in 16/37 HD (43.2%) and in 7/33 (21.2%) non-HD (P < 0.05). Differences were recognized in HDL-cholesterol, LDL-cholesterol and TG levels (38.2 +/- 12.5 mg/dl and 56.7 +/- 18.5 mg/dl, 140.4 +/- 57.1 mg/dl and 115.6 +/- 33.6 mg/dl, 169.9 +/- 89.4 mg/dl and 115.7 +/- 75.1 mg/dl, in HD and non-HD, respectively, P < 0.05). First visit proteinuria was found in all HD patients, and in 6/34 (17.6%) non-HD. The difference in previous treatment refusal, for 7 or more years, was significant with 23/36 (58.9%) HD patients and only 1/25 (4.0%) non-HD patients (P < 0.001) having a history of prolonged non-compliance with diabetic treatment. Diabetic retinopathy, non-proliferative and proliferative, hypertension and a family history of hypertension, elevated triglyceride and LDL-cholesterol, low HDL-cholesterol, first visit proteinuria, and prolonged non-compliance correlated with progression to ESRD. We advocate expanding diabetic education to include prevention of complications such as diabetic nephropathy.

In older type II diabetics, complications progress more rapidly than in younger diabetics for any given degree of hyperglycemia. Therefore, it is important to closely monitor blood glucose levels. When their sugars are controlled, older diabetics will have less nocturia and polyuria; fewer infections; better wound healing; a decrease in the rate of progression of cataracts, diabetic retinopathy, and nerve and renal disease; and better control of dyslipidemia. To learn some useful tips for managing older patients with type II diabetes, GERIATRICS reader David B Jack, MD, interviewed Nancy J.V. Bohannon, MD, for this "Ask the Expert" article.

To examine the characteristic features of risk factors for macroangiopathy (MA) in nonobese Japanese NIDDM patients, 899 NIDDM patients with and without MA were registered from 40 facilities. Of these, 386 subjects were identified as having any form of MA (total MA); these included 211 with ischemic heart disease (IHD), 163 with cerebrovascular disease (CVD), and 77 with peripheral vascular disease (PVD). Univariate analyses revealed the following common risk factors for total MA, IHD, CVD, and PVD: age, hypertension, systolic blood pressure (sBP) or diastolic blood pressure (dBP), duration of diabetes, diabetic microangiopathy (retinopathy, nephropathy, and neuropathy), low HDL cholesterol level, and higher LDL cholesterol/HDL cholesterol ratio. Additional significant risk factors for specific conditions were also identified, respectively, as male sex for total MA, IHD, and PVD, smoking for IHD and PVD, and high fasting plasma glucose level for total MA and CVD. With stepwise multivariate logistic regression analysis, older age, duration of diabetes, smoking, and low LDL cholesterol/HDL cholesterol ratio were identified as significant and independent risk factors for total MA, IHD, CVD, and PVD. Other risk factors identified were high dBP for IHD, CVD, and PVD, high sBP for total MA, and low BMI for PVD. These results clearly demonstrated that duration of diabetes, smoking, hypertension, and dyslipidemia are major risk factors for MA in NIDDM patients. Since the mean BMI was similar for both groups (approximately 23 kg/m2) and there were no significant differences in immunoreactive insulin levels before and after 75-g oral glucose challenge testing, obesity and hyperinsulinism at the time of the analyses were not considered to play an important role for the pathogenesis of MA in Japanese NIDDM patients. By using the chi 2 test, cutoff points were determined for six of the most commonly measured risk factors. The cutoff point was the level beyond which a significantly higher prevalence of MA occurred. The cutoff points (rounded slightly upward in some cases) for fasting plasma glucose, sBP, dBP, serum total cholesterol level, serum triglyceride level, and BMI were 140 mg/dl, 140 mmHg, 80 mmHg, 180 mg/dl, 120 mg/dl, and 23 kg/m2, respectively. When these cutoff points were used as control criteria, the prevalence of MA was significantly lower in subjects whose risk factor measurements remained under the proposed control criteria for four or more of the six variables. In conclusion, in nonobese NIDDM patients, age, hypertension, and dyslipidemia were found to be risk factors for MA. Duration of diabetes was also demonstrated as an independent risk factor, indicating the close association of deranged glucose metabolism with the pathogenesis of MA in NIDDM patients. It seems to be crucial to control these risk factors for the prevention of MA in NIDDM patients.

Renal disease is accompanied by specific alterations of the lipoprotein metabolism. While marked hyperlipidemia is a characteristic finding in the nephrotic syndrome, the dyslipoproteinemia of renal insufficiency is predominantly reflected in an abnormal apolipoprotein pattern but does not necessarily include elevated plasma lipid concentrations. The specific changes in nephrotic syndrome include increased formation primarily of cholesterol-rich and to a varying extent of triglyceride-rich ApoB-containing lipoproteins in the VLDL-LDL density range with little or no change among the ApoA-containing lipoproteins in HDL. The dyslipoproteinemia of renal failure is, on the other hand, mainly characterized by a decreased catabolism of the triglyceride-rich ApoB-containing lipoproteins with increased concentrations of partially metabolized lipoproteins of intermediate and very low density and a decreased concentration of ApoA-containing lipoproteins in HDL. In addition, increased levels of Lp(a) are found both in the nephrotic syndrome and in renal failure. Dialysis treatment appears to have only a modest influence on the renal dyslipoproteinemia. Due to its atherogenic character, the dyslipidemia of renal disease may be related to the accelerated development of cardiovascular disease in these patients.

Patients with renal disease have an increased cardiovascular mortality. Hyperlipidemia, a hallmark of renal disease, is recognized as a principal cause of atherosclerosis. However, it is difficult to prove a pathogenetic role of renal dyslipidemia per se in this increased cardiovascular risk since multiple risk factors are often present in patients with progressive renal insufficiency, e.g. hypertension, diabetes and hypercoagulability. However, evidence is accumulating demonstrating detrimental effects of hyperlipidemia during both initiation and progression of the atherosclerotic process. The present review discusses this evidence in patients with renal disease, and the possible implications for treatment.

Dyslipidemia in end-stage renal disease is a common problem and may contribute to the high rates of morbidity and mortality in this population. Recent studies indicate that defective lipolysis is a major factor in the development of this disorder which is characterized by increased levels of very-low-density-lipoprotein remnant particles, hypertriglyceridemia and occasionally hypercholesterolemia. There are no prospective long-term studies on the effect of lipid-lowering treatment on morbidity and mortality related to dyslipidemia. Therefore, at present pharmacologic treatment of hyperlipidemia should be undertaken in patients with severe hypertriglyceridemia (> 500 mg/dl) or hypercholesterolemia (LDL > 130 mg/dl) who are at high risk for coronary artery disease. This review discusses the pathogenesis of dyslipidemia, common clinical patterns of hyperlipidemia and various nonpharmacologic and pharmacologic treatment options.

Dyslipidemia is common in patients with renal disease, may contribute to the high incidence of cardiovascular disease, and may play a role in progressive renal injury. Recent studies have shown that newer antilipemic agents appear to be safe and effective in patients with renal disease. This should make it possible to conduct large, controlled clinical trials examining the effect of lipid-lowering strategies on cardiovascular disease, and on renal disease progression.

Maintenance dialysis patients experience an exceedingly high incidence of arteriosclerotic cardiovascular disease (CVD) events that are poorly predicted by traditional CVD risk factor indices. We evaluated the prevalence of three non-traditional CVD risk factors, i.e. hyperhomocysteinemia, hyperfibrinogenemia, and lipoprotein (a) Lp(a)) excess, and combined hyperhomocysteinemia, hyperfibrinogenemia, and Lp(a) excess, in maintenance dialysis patients. Fasting total plasma homocysteine (Hcy), fibrinogen, Lp(a), glucose, and total and HDL cholesterol levels, and traditional CVD risk factor (i.e. glucose tolerance, smoking, hypertension, dyslipidemia) prevalences were assessed in 71 dialysis patients and 71 age, sex, and race matched Framingham Study controls free of clinical renal disease, with normal serum creatinine (< or = 1.5 mg/dl). Mean plasma Hcy 23.7 vs. 9.9 microM, P = 0.0001), fibrinogen (457 vs. 309 mg/dl, P = 0.0001), and Lp(a) (30 vs. 17 mg/dl, P = 0.0070) levels were substantially increased in the dialysis patients. Matched odds ratios (with 95% confidence intervals), dialysis patients/controls, for hyperhomocysteinemia, hyperfibrinogenemia, and Lp(a) excess, alone or combined, were markedly greater in the dialysis patients, with no evidence of confounding by the traditional CVD risk factors: hyperhomocysteinemia, 105.0 (29.9-368.9); hyperfibrinogenemia, 16.6 (6.6-42.0); Lp(a) excess, 3.5 (1.5-8.4); all three combined 35.0 (5.7-199.8). Given in vitro evidence that Hcy, Lp(a), and fibrinogen interact to promote atherothrombosis, combined hyperhomocysteinemia, hyperfibrinogenemia, and Lp(a) excess may contribute to the high incidence of vascular disease sequelae experienced by dialysis patients, which is inadequately explained by traditional CVD risk factors. Controlled, prospective studies of well-characterized maintenance dialysis cohorts are urgently required to substantiate this hypothesis.
