We studied the levels of cardiovascular risk factors in a population sample of 511 men and 920 women aged 65-74 years and living in East Finland. Altogether 312 men and 515 women had normal glucose tolerance, 84 men and 158 women impaired glucose tolerance (IGT), 33 men and 59 women newly diagnosed non-insulin-dependent diabetes (NIDDM) detected at the survey, and 82 men and 188 women previously diagnosed NIDDM. Subjects with IGT or newly diagnosed NIDDM had higher levels of total triglycerides and apolipoprotein B and lower levels of HDL cholesterol and apolipoprotein A1 than subjects with normal glucose tolerance, similarly as in previously diagnosed NIDDM. Furthermore, subjects with IGT or newly diagnosed NIDDM were more obese, had higher waist-hip ratio, and more frequently hypertension than subjects with normal glucose tolerance. Thus, asymptomatic hyperglycemia in the elderly is not a benign phenomenon, but is associated with similar adverse changes in cardiovascular risk factors as in middle-aged subjects.

Fasting total cholesterol (TC), triglycerides (TG), HDL cholesterol (HDL C), apolipoprotein A1 (apo A1) and apolipoprotein B (apo B) were measured in 35 non-insulin dependent diabetic patients treated by diet with or without sulphonylureas and 35 control subjects matched for age, sex, and body mass index. Ratios of apolipoprotein and lipid were calculated. The diabetics were well controlled with a mean (+/- SD) glycosylated haemoglobin (HbA1) of 8.5 +/- 1.3% (normal range less than 8%). Compared to non-diabetic control subjects apo A1: HDL C, apo B: TC, and apo B: calculated LDL C were significantly higher in the NIDDM patients, (112.9 +/- 26.3 vs 83.0 +/- 28.7, p less than 0.001, 15.89 +/- 1.68 vs 14.22 +/- 3.48, p less than 0.01, and 24.32 +/- 3.19 vs 22.33 +/- 5.49, p less than 0.05 respectively). These findings reflect differences in cholesterol content in the absence of differences in apolipoprotein concentrations between the NIDDM and control groups. The cardiovascular risk ratio HDL C: non HDL C was significantly lower in the NIDDM patients (0.25 +/- 0.09 vs 0.31 +/- 0.15, p less than 0.01), but there was no difference in apo A1:apo B (1.42 +/- 0.42 vs 1.43 +/- 0.52, NS). Although apo A1: apo B correlated well with HDL C:non HDL C in both NIDDM and controls (r = 0.88, 0.72, p less than 0.001 respectively) the slope of the relationships differed b = 4.01 NIDDM vs 2.50 controls (95% confidence intervals for difference is 0.22-2.78). Simple widely available methods can identify abnormalities of lipoprotein content in treated NIDDM patients. Both HDL and LDL contain less cholesterol.(ABSTRACT TRUNCATED AT 250 WORDS)

Lp(a) has been considered as an independent risk factor for atherosclerosis, mainly for coronary heart disease. Recent epidemiologic studies have demonstrated elevation of Lp(a) serum concentration in diabetes mellitus. Atherosclerosis is the most common cause of death in diabetic patients, but there is little information available concerning the importance of Lp(a) in these patients. We investigated the relationship between Lp(a) serum concentration and the presence of chronic diabetic complications. Lp(a) was determined in 14 IDDM patients and 62 NIDDM patients. Median Lp(a) serum concentration in diabetics was 21.8 mg/dl, which was significantly higher than in nondiabetic controls described before. Glucose, HbA1c, fructosamine, total cholesterol, triglycerides, HDL-cholesterol, apolipoprotein A1, B and E were not associated with raised Lp(a) values. With increasing Lp(a) levels, higher prevalences of retinopathy and of albuminuria were observed. We conclude that in diabetic patients, Lp(a) levels are elevated compared with non-diabetic subjects, and that higher Lp(a) levels are associated with higher prevalences of retinopathy and of albuminuria.

Metabolic disturbances such as hyperinsulinaemia, dislipoproteinaemia and glucose intolerance are often associated with essential hypertension and markedly affect cardiovascular morbidity in hypertensive patients. In order to shed some light on the prognostic significance of white coat hypertension (raised clinic and normal ambulatory blood pressure), we compared the metabolic profile in a group of white coat and sustained previously untreated hypertensives. We studied 84 newly detected hypertensive patients (49 men, 35 women, 47 +/- 8 years, range 28-59 years). Subjects with obesity (BMI > 30), NIDDM and target organ damage were excluded. Ambulatory blood pressure monitoring was performed by SpaceLabs 90207-31. Total cholesterol and triglycerides, LDL-cholesterol, HDL-cholesterol (HDL-C) and subclasses HDL2 and HDL3 cholesterol as well as apolipoprotein A1 and B were measured in fasting plasma. Glucose and insulin were determined in fasting and postload (glucose 75 g plasma. Twenty patients (24%, 8 men and 12 women) were classified as white coat hypertensives. No differences in age, BMI and waist to hip ratio were observed between white coat and sustained hypertensive patients. Plasma glucose and lipoprotein levels were similar in the two groups. Fasting and postload insulin levels were significantly lower in white coat hypertensives (fasting insulin 7.1 +/- 2.9 vs. 12 +/- 8.6 microU/ml, P < 0.02; insulin 120 minutes 48 +/- 27 vs. 65 +/- 41 microU/ml, P < 0.05); glucose/insulin rate was higher in white coat than in sustained hypertensive patients (15 +/- 7 vs. 11 +/- 7, P = 0.03).(ABSTRACT TRUNCATED AT 250 WORDS)

Increased lipid peroxidation has been commonly observed in diabetic patients as compared to control subjects. However, studies on the relationship to metabolic control have yielded conflicting results and no data are available on the relationship of hyperinsulinaemia to lipid peroxidation. We investigated, in well-characterized groups of 93 patients with non-insulin-dependent diabetes mellitus, 22 subjects with impaired glucose tolerance (IGT) and 96 subjects with normal glucose tolerance (NGT), the determinants of plasma lipid peroxidation measured by plasma thiobarbituric acid reactive substances (TBARS). These were significantly higher in subjects with IGT (1.04 +/- 0.48 mumol I-1) and in NIDDM patients (1.00 +/- 0.48 mumol I-1) than in those with NGT (0.75 +/- 0.46 mumol I-1; p < 0.05). The glucose tolerance status was the major determinant of increased lipid peroxidation even after controlling for the effects of age, sex, body mass index, physical activity, use of alcohol, smoking, and the use of diuretics. In regression analyses the major determinants of plasma TBARS were fasting plasma glucose, insulin, and apolipoprotein A1 (inversely) levels. To conclude, plasma TBARS were increased in impaired glucose tolerance and in diabetes and they were related to prevailing plasma glucose and insulin levels, suggesting a role for insulin resistance in increased lipid peroxidation process. On the contrary, apolipoprotein A1 may have protective effects in this respect.

To assess the prevalence of urinary albumin excretion abnormalities and their associations with cardiovascular disease or its classical risk factors in type 2 diabetes mellitus, 1348 clinic-proceeding patients have been studied retrospectively. The overnight urinary albumin excretion rate, blood pressure, smoking, ophthalmic and cardiovascular status, current therapies, estimates of glycemic control, plasma lipids, serum creatinine and uric acid have been ascertained. 767 (56.8%) patients were found normoalbuminuric, 461 (34.1%) microalbuminuric and 120 (8.9%) macroalbuminuric. In bivariate analyses, the urinary albumin excretion rate had statistically significant (P < 0.05) relationships with age, duration of diabetes, male sex, waist-to-hip ratio, systolic and diastolic pressure, coronary heart disease, cerebrovascular disease, peripheral vascular disease, hypertension, antihypertensive therapy, laser-treated retinopathy, kind of treatment, smoking habit, fasting glycaemia, HbA1c, creatinine, uric acid, triglycerides, high density lipoprotein (HDL)-cholesterol and apolipoprotein B. Borderline statistically significant (P < 0.1) relationships were found with hypolipidaemic therapy, insulin dose, non-HDL-cholesterol, apolipoprotein A1 and lipoprotein (a). In a multivariate stepwise logistic regression model, HbA1c, hypertension, male sex, age, diastolic blood pressure, coronary heart disease and body-mass index were sequentially selected as variables independently associated with microalbuminuria. Serum creatinine, HbA1c, male sex and hypertension were sequentially selected as independently associated with macroalbuminuria. Micro and macroalbuminuria are frequent abnormalities associated with poorly controlled and complicated disease, with overt cardiovascular disease and its classical risk factors as well as with the male sex.

Non-insulin dependent diabetes (NIDDM) is associated with an increased risk of peripheral vascular disease (PVD), but within the diabetic population the relationship between lipid profile and PVD has not been clearly defined. In this study we examined the association of lipid parameters and in particular low density lipoprotein (LDL) particle size, with the presence of PVD in subjects with and without NIDDM. 41 NIDDM patients and 31 non-diabetic subjects with PVD in the absence of rest pain or ulceration, defined by ankle-brachial index measurements and duplex scanning, were compared with 41 NIDDM and 31 euglycemic control subjects of comparable age and sex, without PVD. In both groups those with PVD were found to have significantly elevated triglycerides (2.7 [2.2-3.3] versus 1.9 [1.6-2.2] mmol/l; P < 0.05 in the diabetic group and 2.0 [1.6-2.3] versus 1.4 [1.1-1.5] mmol/l; P < 0.05 in the non-diabetic group), decreased apolipoprotein A1 (124 +/- 3 versus 139 +/- 5 mg/dl; P < 0.01 in the diabetic group and 133 +/- 4 versus 147 +/- 4 mg/dl; P < 0.05 in the non-diabetic group) and decreased LDL particle size (25.4 +/- 0.1 versus 25.8 +/- 0.1 nm; P < 0.01 in the diabetic group and 26.0 +/- 0.1 versus 26.3 +/- 0.1 nm; P < 0.05 in the non diabetic group). In the non-diabetic group apolipoprotein[a] (365 [239-554] versus 184 [17-266] U/l; P < 0.01), total cholesterol (6.3 +/- 0.2 versus 5.6 +/- 0.2 mmol/l; P < 0.05), LDL cholesterol (4.1 +/- 0.2 versus 3.6 +/- 0.2 mmol/l; P < 0.05) and apolipoprotein B (146 +/- 8 versus 117 +/- 5 mg/dl; P < 0.05) were also found to be associated with PVD although these associations were not observed in the group with diabetes. In addition, 11 NIDDM subjects and 11 non-diabetic subjects with rest pain or ulceration were compared to the corresponding groups with uncomplicated PVD and had lipid profiles with significantly lower levels of total cholesterol and LDL cholesterol. We conclude that the dyslipidemic profile characterized by increased triglyceride level, decreased apolipoprotein A1 level and small dense LDL is associated with uncomplicated PVD in both NIDDM and non-diabetic subjects.

This study investigated the effects of oral combined hormone replacement therapy (OCHRT) on lipid concentrations and subpopulation distribution of lipoproteins in nine postmenopausal women with type 2 diabetes mellitus and moderate glycemic control. After 16 weeks of continuous daily therapy of conjugated estrogens 0.625 mg and medroxyprogesterone 2.5 mg, the mean concentration of high-density lipoprotein (HDL) cholesterol showed a statistically significant increase of 16.7%, predominantly in the HDL2 subfraction. No statistically significant changes in mean concentrations of total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, very low-density lipoprotein (VLDL) triglycerides, apolipoprotein A1, or apolipoprotein B were evident. Likewise, no changes were found in the average diameter of VLDL, LDL, or HDL particles; triglyceride concentrations of VLDL subfractions; cholesterol concentrations of LDL subfractions; or chemical composition of plasma LDL. These findings lend further support to the use of OCHRT in postmenopausal women with diabetes to decrease their risk for coronary artery disease.

Spirulina, with its high concentration of functional nutrients, is emerging as an important therapeutic food. This study aimed to evaluate the hypoglycemic and hypolipidemic role of Spirulina. Twenty-five subjects with type 2 diabetes mellitus were randomly assigned to receive Spirulina (study group) or to form the control group. At baseline, the control and study groups were matched for various variables. The efficacy of Spirulina supplementation (2 g/day for 2 months) was determined using the preintervention and postintervention blood glucose levels, glycosylated hemoglobin (HbA(1c)) levels, and lipid profiles of the diabetic subjects. Two-month supplementation with Spirulina resulted in an appreciable lowering of fasting blood glucose and postprandial blood glucose levels. A significant reduction in the HbA(1c) level was also observed, indicating improved long-term glucose regulation. With regard to lipids, triglyceride levels were significantly lowered. Total cholesterol (TC) and its fraction, low-density lipoprotein cholesterol (LDL-C), exhibited a fall coupled with a marginal increase in the level of high-density lipoprotein cholesterol (HDL-C). As a result, a significant reduction in the atherogenic indices, TC:HDL-C and LDL-C: HDL-C, was observed. The level of apolipoprotein B registered a significant fall together with a significant increment in the level of apolipoprotein A1. Therefore, a significant and favorable increase in the ratio of A1:B was also noted. These findings suggest the beneficial effect of Spirulina supplementation in controlling blood glucose levels and in improving the lipid profile of subjects with type 2 diabetes mellitus.

Type 2 diabetes mellitus and the closely related metabolic syndrome are associated with significant risk for cardiovascular disease. Recent evidence suggests that both conditions are increasing in epidemic proportions. Dyslipidemia is characterized by increased triglyceride-rich lipoproteins; low high-density lipoprotein cholesterol; small, dense low-density lipoprotein particles; increased postprandial lipemia; and abnormal apolipoprotein A1 and B metabolism. All these lipoprotein disturbances accelerate atherosclerosis in these patients. It is likely that many patients will need combinations of lipid-modifying therapy to achieve American Diabetes Association (ADA), Adult Treatment Panel III, and American Heart Association (AHA)/American College of Cardiology (ACC) guidelines to help prevent cardiovascular disease and death.
