Plasma lipoproteins were studied longitudinally at the 1st, 2nd, and 3rd trimester of gestation and at postpartum and postlactation in 12 age-matched PGDM women, 9 GDM women, and 12 healthy control subjects. FPG and HbA1c were higher in every case in PGDM women than in control subjects, whereas in GDM patients, glucose was augmented only after parturition. FFA and beta-hydroxybutyrate levels were higher in both PGDM and GDM patients than in control subjects during gestation but not after parturition. Total TGs and VLDL, LDL, and HDL TGs increased with gestational time in the three groups and declined at postpartum, and although total cholesterol and VLDL, LDL, and HDL cholesterol followed a similar trend, their rise was less pronounced, and the decline after parturition was slower than that of the TGs in the three groups, with no difference among them. The VLDL TG/cholesterol ratio declined in the three groups at the 3rd gestational trimester, whereas in both LDL and HDL, the TG/cholesterol ratio, but not the cholesterol/phospholipid ratio, increased during gestation in the three groups, indicating a specific enrichment of TGs in these particles. The increase in apoA-I and apoB with gestation was parallel to the respective changes in HDL and LDL cholesterol and, again, no difference was observed between the three groups. Plasma levels of beta-estradiol, progesterone, and prolactin increased sharply with gestation and declined at postpartum in the three groups, but absolute values of beta-estradiol and prolactin, at the three trimesters of gestation, were lower in PGDM patients, but progesterone levels were lower than controls in GDM women only at the 3rd trimester.

High density lipoprotein subfraction 2 (HDL1)-cholesterol level is usually decreased in Type 2 (non-insulin-dependent) diabetes. A study was carried out in 251 Type 2 diabetic patients (106 males [M], 145 females [F]) and in 120 non diabetic controls in order to determine the influence of hypertriglyceridaemia and obesity on the HDL2-cholesterol level and to analyse the relationship between HDL2-cholesterol level and atherosclerosis (coronary heart disease, peripheral atherosclerosis or cerebral vascular disease), in Type 2 diabetes. Influence of hypertriglyceridaemia and obesity on HDL2-cholesterol level was studied by comparing the mean values of HDL2-cholesterol between diabetics and controls, after controlling for hypertriglyceridaemia and obesity, and by a multiple linear regression test. A stepwise logistic regression was performed to analyse the association between the prevalence of atherosclerosis and several variables: age, duration of diabetes, hypertension, cigarette smoking, body mass index, mean glycaemia, total cholesterol, triglyceride, HDL-cholesterol, HDL2-cholesterol and HDL3-cholesterol levels. In both men and women, when both of the factors (hypertriglyceridaemia and obesity) were present of when only one was, HDL2-cholesterol level was significantly lower in the diabetic population, compared with controls. But when obesity and hypertriglyceridaemia were absent, HDL2-cholesterol level, in the diabetic population, was not significantly different from controls (M: 17.9 +/- 13.3 vs 20.5 +/- 13.8 mg/dl: NS; F: 30.1 +/- 21.5 vs 27.6 +/- 14.2 mg/dl: NS).(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to evaluate the prevalence of arterial hypertension and other risk factors in patients suffering from peripheral arterial disease (PAD) in two clinical samples (1.: 102 patients with PAD 69 M, 33 F, studied in our angiology laboratory, matched for sex and age with 102 healthy volunteers; 2.: 184 hospitalized patients, 80 M, 104 F, mean age 57.2 +/- 10.8, with PAD) and in two epidemiological cohorts (1.: Trabia Study, 835 subjects; 2.: Casteldaccia Study, 723 subjects). All patients were subjected to a full clinical and laboratory examination, including the determination of the ankle/arm pressure ratio (Winsor index, positive for PAD when lower than 0.95). In the first clinical study we observed a significantly (p < 0.01) greater prevalence of arterial hypertension (51.9 vs 9.8%), hypercholesterolemia (48.2 vs 21.6%), hypertriglyceridemia (53.7 vs 26.1%), smoking habit (64.3 vs 44.2%), and hyperglycemia (26 vs 7,9%) in PAD patients than in controls. In the second clinical study considering separately the patients under and over 65 years, all risk factors resulted to be more prevalent in younger people than in the aged, except for diabetes and hypertension. In our epidemiological experience, the prevalence of PAD increases with aging, above all in males. In the Trabia Study the risk factors, more associated with PAD, were hypercholesterolemia, smoking and obesity (41.18%) in males and hypertension and hypercholesterolemia (33.3%) and obesity (25%) in females. In the Casteldaccia Study the most important risk factors were smoking (64.28%), hypercholesterolemia (42.86%) and hypertriglyceridemia (35.71%) in males, and obesity (60%), hypercholesterolemia (30%) and diabetes (20%) in females. Cholesterol levels and smoking were significantly higher in PAD patients than in the general population, whereas hypertriglyceridemia and glycemia were not. Arterial hypertension was significantly associated with PAD in the Trabia but not in the Casteldaccia Study. Obesity was significantly associated to PAD in females in both studies. In the Casteldaccia Study, lower HDL-cholesterol levels were observed in PAD patients, above all in males, whereas significantly greater Apo-B values and lower Apo-A1 levels (in males) were shown. The different levels of associated risk factors and their prevalence in PAD patients confirm the multifactorial pathogenesis of atherosclerosis. The exact role of each risk factor in the genesis of PAD is difficult to be evaluated due to the complex biological and statistical interrelationships among different risk factors. However, the management of associated risk factors may favourably influence the risk profile in each patient suffering from PAD.

The aim of this study was to assess the prevalence of peripheral vascular disease (PVD) in newly diagnosed diabetic patients and the possible relationship to various risk factors. One hundred and twenty non-insulin-dependent diabetics (NIDDs) aged 50-70 years and 93 non-diabetic subjects, matched for age and sex, were studied using Doppler ultrasound. None had a history of alcoholic abuse, while 12 diabetic and 8 non-diabetic subjects were smokers. There were 6 male subjects with PVD (5 NIDDs, 1 control subject) and 2 female diabetic subjects with PVD (p: No SD). In group of male diabetics with PVD, HDL-C levels were found to be lower and triglyceride levels higher, than in those without diabetes, but the difference was not significant. Hypertension, body mass index and smoking were not associated with the presence of PVD in either female or male diabetic subjects. It is concluded that, although PVD tended to be more common in men with newly diagnosed diabetes, the overall findings support the view that macrovascular disease is related to duration of diabetes.

Hyperlipidaemia, in particular raised concentrations of serum triglycerides, together with raised plasma non-esterified fatty acid concentrations, is common in patients with Type 2 (non-insulin-dependent) diabetes mellitus and may be associated with insulin insensitivity. Thirty non-obese Type 2 diabetic patients (15 controlled with diet alone and 15 with diet plus oral sulphonylurea therapy) were therefore recruited to take part in a double-blind, randomized, crossover comparison of acipimox (250 mg three times daily for 3 months) and placebo. Serum lipids, blood glucose control, insulin sensitivity, and glucose tolerance were measured before and after each treatment period. There was a significant decrease in serum triglycerides (2.05 +/- 1.08 vs 2.91 +/- 1.75: p < 0.005), cholesterol (5.66 +/- 1.02 vs 6.26 +/- 1.17: p = 0.0005), and apoprotein B (1.32 +/- 0.23 vs 1.44 +/- 0.25: p < 0.05) while HDL cholesterol and apoprotein A-1 concentrations were unchanged. There was no change in blood glucose control measured by fasting glucose, insulin, and HBA, concentrations, but there was a significant improvement in insulin action assessed by glucose-insulin infusion. Although plasma non-esterified fatty acid concentrations were lower during the oral glucose tolerance test after acipimox, there was no difference in either the peak or 2-h plasma glucose concentrations and the total area under the glucose curve did not change. Acipimox was well tolerated and no patients withdrew from the study for drug-related symptoms. Thus, acipimox effectively lowers serum cholesterol and triglycerides in patients with Type 2 diabetes without adversely altering blood glucose control, and appears to improve insulin sensitivity.

Risk factor analysis in coronary artery disease was conducted in 303 patients who underwent coronary arteriography to identify associations between personal characteristics and the prevalence of coronary heart disease. Age, sex, obesity, smoking, alcohol intake, hypertension, diabetes mellitus, serum uric acid, total cholesterol, LDL- and HDL-cholesterol, triglyceride, and atherogenic indices were statistically analyzed. All 13 variables were first compared between patients with positive and negative ergonovine tests. Only total cholesterol was significantly different, while significant differences in age, sex, history of diabetes, total cholesterol, LDL- and HDL-cholesterol, triglyceride and atherosclerotic indices were observed between patients with and without organic coronary artery stenosis. A multivariate analysis was performed, and the resulting equation was tested using the remaining patients. Logistic analysis of all 13 variables identified 5 (age, sex, diabetes mellitus, LDL- and HDL-cholesterol) which accounted for the differences between patients with and without significant coronary artery disease and that were validated in the test group. The sensitivity for prediction of coronary artery disease was 75.8%, specificity 68.5%, and predictive accuracy 71.5% in the test group. Thus, risk factor analysis appears to be very valuable in screening subjects with high-risk organic coronary stenosis and in optimizing the preventive and therapeutic modalities, but not in predicting vasospastic subjects.

Hypertension is a powerful predisposing risk factor for cardiovascular disease at all ages and in both sexes. Epidemiological assessment indicates the largest risk ratios for stroke and congestive heart failure (CHF), but coronary heart disease (CHD) is the most common and most lethal sequela of hypertension. Examination of the risk of cardiovascular sequelae in the hypertensive population indicates that this is not uniform and varies over a 10-fold range, depending on the associated risk factors. Systolic pressure merits greater consideration than the diastole pressure because isolated systolic hypertension is a powerful cardiovascular risk at all ages. Furthermore, recent trials have indicated the benefit of therapy for systolic-based hypertension in the elderly, even using a diuretic, for coronary disease as well as stroke. Persons with hypertension have a high prevalence of associated cardiovascular risk factors, including elevated cholesterol, reduced HDL-C, diabetes, left ventricular hypertrophy (LVH), and obesity. About 9% under the age of 65 years have an associated overt cardiovascular disease; above age 65 about 30% are so afflicted. Each of these risk factors can double the risk associated with hypertension. Because they are so common, a large fraction of the disease sequelae of hypertension is attributable to these associated risk factors. The high risk of coronary disease in hypertensive patients is concentrated in those with a high total/HDL-cholesterol ratio, impaired glucose tolerance, high fibrinogen, ECG abnormalities, and cigarette smokers. Stroke risk in hypertensive persons is concentrated in those with cardiovascular disease, diabetes, atrial fibrillation, LVH and cigarette smoking.(ABSTRACT TRUNCATED AT 250 WORDS)

Hypertension, dyslipidaemia, glucose intolerance (associated with insulin resistance and compensatory hyperinsulinaemia) and other abnormalities are complementary coronary risk factors which often occur in association. A familial trait for essential hypertension seems to coexist commonly with defects in carbohydrate and lipoprotein metabolism which can be detected before the appearance of hypertension. Diabetes mellitus as well as obesity promotes the development of hypertension and dyslipidaemia. Moreover, certain drugs used for antihypertensive therapy can further modify lipoprotein and glucose metabolism. Thiazides in high dosage and loop-diuretics can increase serum low-density-lipoprotein cholesterol (LDL-C) and/or very-LDL-C and the total C/high-density lipoprotein cholesterol (HDL-C) ratio, while HDL-C is largely unchanged; triglycerides (Tg) are also often elevated. Premenopausal women may be protected from this side effect. Whether diuretic-induced dyslipidaemia is dose-dependent and low thiazide doses (i.e. hydrochlorothiazide < or = 12.5 mg daily) are less active, awaits clarification. The diuretic-antihypertensive agent, indapamide, given at a dose of 2.5 mg.day-1, seems to exert no relevant effect on serum lipoprotein or glucose metabolism. The potassium-sparing diuretic, spironolactone, also may be largely neutral with regard to lipids. Moreover, potassium sparing diuretics may possibly counteract, at least in part, a dyslipidaemic influence of potassium-loosing diuretics in medium dose. Drug-induced dyslipidaemia, as well as glucose intolerance, represent potentially adverse influences. In the hypertensive population, effective blood pressure control with traditional drug therapy based on thiazide-type diuretics in high dosage led to a distinct decrease in cerebrovascular morbidity and mortality, but a lesser decrease in coronary events.(ABSTRACT TRUNCATED AT 250 WORDS)

Japanese-American men have higher rates of non-insulin-dependent diabetes mellitus and coronary heart disease than same-aged men in Japan. Associations of educational attainment with either non-insulin-dependent diabetes mellitus or coronary heart disease were examined in a sample of 229 second-generation Japanese-American men (aged 45 to 74 years) living in King County, Washington (1984 through 1985). Men with a terminal school education showed higher frequencies of both disease compared to men with any college education and to men with high school educations. Occupation, income, diet, physical activity, weight, insulin, lipids, and lipoproteins were examined to determine whether they could account for the observed associations of educational attainment with disease. Logistic regression analysis indicates that the association of educational attainment with risk of coronary heart disease is explained, in part, by the larger average body mass index, higher total and VLDL triglyceride, and lower HDL and HDL-2 cholesterol observed in men with technical school educations compared to the other men. The association of educational attainment with risk of non-insulin-dependent diabetes is not explained by any of the factors examined. The findings suggest that attainment of a college education ameliorates some of the negative effects of westernization on the health of Japanese-American men.

The Authors examine the relationship between diabetes mellitus, lipid metabolism and atherosclerosis with particular emphasis on the role of insulin and on the therapeutic consequences. The results of a study on the efficacy and tolerability of simvastatin in the treatment of hypercholesterolemia in non insulin-dependent diabetic patients are reported. Simvastatin administration induce a significant reduction and increase in total and HDL cholesterol levels respectively contributes to the decrease of triglycerides without interfering with the metabolic control of diabetic condition.
