Recent data indicate that low-birthweight adults are at a higher risk than their high-birthweight peers of developing ischemic heart disease or a cluster of conditions known as the IRS, which includes dyslipidaemias, hypertension, unfavorable body fat distribution and NIDDM. Thus far these observations have been limited to Caucasians from the United Kingdom. we extended these observations to a broader segment of the general population by studying the association of birthweight and adult health outcomes in a biethnic population of the United States. We divided a group of 564 young adult Mexican-American and non-Hispanic white men and women participants of the San Antonio Heart Study into tertiles of birthweight and compared metabolic, anthropometric, haemodynamic, and demographic characteristics across these tertile categories. Additionally, we studied birthweight as a predictor of the clustering of diseases associated with the IRS, defined as any two or more of the following conditions: hypertension, NIDDM or impaired glucose tolerance, dyslipidaemia. Normotensive, non-diabetic individuals whose birthweight was in the lowest tertile had significantly higher levels of fasting serum insulin and a more truncal fat deposition pattern than individuals whose birthweight was in the highest tertile, independently of sex, ethnicity, and current socioeconomic status. Also, the odds of expressing the IRS increased 1.72 times (95% confidence interval: 1.16-2.55) for each tertile decrease in birthweight. These findings were independent of sex, ethnicity, and current levels of socioeconomic status or obesity. In conclusion, low birthweight could be a major independent risk factor for the development of adult chronic conditions commonly associated with insulin resistance in the general population.

In 370 non-insulin-dependent diabetic (NIDDM) patients less than 66 years of age, we found the prevalence of albuminuria (> 300 mg 24 h-1) to be 13.8%. Males had a higher prevalence than females (19 vs. 5%). A kidney biopsy was performed in 35 patients. The biopsy revealed diabetic glomerulosclerosis in 77% of the cases and a variety of non-diabetic glomerulopathies in the remaining 23%. Fifty-six per cent of the patients with diabetic glomerulosclerosis had diabetic retinopathy, whereas none of the patients with non-diabetic glomerulopathies had signs of retinopathy. The presence of diabetic retinopathy strongly suggests that diabetic glomerulosclerosis is the cause of albuminuria. During a 5-year (range 1-7 years) prospective study, the course of kidney function was followed in 26 NIDDM patients with diabetic glomerulosclerosis. The glomerular filtration rate declined, and elevated systolic blood pressure was positively correlated to the rate of decline. The frequency of diabetic complications increased with increasing levels of urinary albumin excretion. In a cross-sectional study of 549 NIDDM patients, the prevalence of proliferative retinopathy was 2, 5 and 12%, the prevalence of hypertension 46, 68 and 85%, and the prevalence of ischaemic heart disease 22, 26 and 46% in normo-, micro-, and macroalbuminuria, respectively. The mortality from cardiovascular disease is increased ninefold in NIDDM patients with macroalbuminuria compared to the non-diabetic background population. The presence of the well-established risk factors cannot account for this finding alone.(ABSTRACT TRUNCATED AT 250 WORDS)

In the Copenhagen Male Study we found an increased risk of ischaemic heart disease (IHD) in men with the Lewis phenotype Le(a-b-). This study investigated whether, within the group of Le(a-b-) men, any conventional risk factors modified their increased risk. Three thousand, three hundred and eighty-three men aged 53 to 75 years were examined in 1985/86 and their morbidity and mortality over the next four years recorded. Three hundred and forty-three men with cardiovascular diseases were excluded at baseline. Potential risk factors examined were: alcohol consumption, physical activity, tobacco smoking, serum cotinine, serum lipids, body mass index, blood pressure, hypertension, non-insulin dependent diabetes mellitus and social class. In eligible men with Le(a-b-), N = 280 (9.6%), alcohol was the only risk factor associated with risk of IHD. There was a significant inverse dose-effect relationship between alcohol consumption and risk. The age-adjusted p-values of trend tests were for risk of non-fatal + fatal IHD: p = 0.03; for risk of fatal IHD: p = 0.02. In eligible men with other phenotypes, N = 2,649 (90.4%) only a limited and non-significant negative association with alcohol. In Le(a-b-) men, a group genetically at increased risk of IHD, the risk was strongly and significantly negatively correlated with alcohol consumption.

Prospective studies showed that hypersecretion of albumin in the urine of patients with type 2 diabetes mellitus is associated with high morbidity and mortality from cardiovascular disease and nephropathy. 65 type 2 diabetes from 6 family medicine practices were studied. Microalbuminuria was found in 37% and was significantly more common in men than in women (53% and 23%, respectively; p < 0.02). Uncontrolled blood glucose levels were also more common in men (p < 0.03). Using logistic regression with microalbuminuria as the dependent variable, a significant correlation was found with male gender, fasting blood glucose 155 mg/dl or more, and systolic blood pressure 159 mm Hg or higher. Among those with microalbuminuria, ischemic heart disease was significantly more common in those 65 years or older than in those younger (p = 0.02). This study strengthens the assumption that type 2 diabetics with microalbuminuria might be at greater risk for developing ischemic heart disease. Strict detection and control are recommended.

A total of 40 patients with diabetes mellitus without anginal episodes and equivalents were studied. 24-hour monitoring identified 2 groups of patients: (1) 13 patients with recorded silent myocardial ischemic episodes and (2) 23 patients without episodes. Four patients were found to have stress-echocardiographic silent myocardial ischemia. Silent myocardial ischemia was detected in 42.5% of patients with diabetes mellitus. The patients from Group 1 exhibited more frequently Type II diabetes mellitus whose duration was over 9 years and concurrent retino- and polyneuropathies. There was a relationship between silent myocardial ischemia to heart failure and myocardial hypertrophy as evidenced by two-dimensional echocardiography. The patients from Group 1 had a higher pain sensitivity threshold than those from Group 2. Autonomic polyneuropathy was observed in 46% of Group 1 patients and in 21% of Group 2 patients.

Angiotensin 1 converting enzyme (ACE) catalyses the step which generates angiotensin II, and also inactivates bradykinin, peptides which play a key role in modulating vascular tone. Plasma ACE levels are under genetic control and up to 50% of the variation is due to an insertion/deletion (I/D) polymorphism of ACE gene with highest levels found in DD homozygotes. Studies have shown an association of diabetic nephropathy and ischaemic heart disease with angiotensin converting enzyme gene polymorphism in subjects with diabetes. We examined the association between diabetic retinopathy and ACE gene insertion/deletion polymorphism in 363 subjects with NIDDM (aged 68.3 +/- 10.7 years; 201 male, 162 female), 186 subjects with IDDM (aged 42.4 +/- 15.0 years; 100 male, 86 female) and 98 controls. These subjects were characterized for ACE I/D polymorphism employing standard primers. Diabetic retinopathy was diagnosed by ophthalmoscopy through dilated pupils by an ophthalmologist and classified as non-proliferative or proliferative retinopathy. As expected, diabetic retinopathy was strongly associated with duration of diabetes (p < 0.001) in both IDDM and NIDDM. Any retinopathy was present in 51% subjects with IDDM and 49% of subjects with NIDDM, while 22% of IDDM subjects and 5% of subjects with NIDDM had proliferative retinopathy. The frequency of I allele was 0.477 vs 0.482 vs 0.510 and D allele was 0.523 vs 0.518 vs 0.490, among subjects with IDDM, NIDDM and controls, respectively. The frequency of ACE I/D genotype was similar in subjects with IDDM, NIDDM, and controls (chi 2 = 0.46, df = 4, p = ns). Presence or absence of retinopathy was not significantly associated with ACE genotype in subjects with IDDM (chi 2 = 3.42, df = 2, p = ns) or NIDDM (chi 2 = 0.51, df = 2, p = ns). Among subjects with retinopathy, there was no significant association between ACE genotype and type of retinopathy. Controlled for duration of diabetes, the frequency of I/D genotype was not significantly different in 271 subjects with retinopathy (IDDM and NIDDM combined) when compared with 86 subjects without retinopathy at 15 years or more after diagnosis of diabetes (chi 2 = 1.29, df = 2, p = ns). These findings indicate that I/D polymorphism of ACE gene is not a useful marker and is unlikely to play a major role in determining genetic susceptibility to diabetic retinopathy or the severity of diabetic retinopathy.

There is limited evidence that raised hematocrit levels may be associated with insulin resistance, which links cardiovascular disease with NIDDM. The association between hematocrit level at screening and the subsequent development of physician-diagnosed NIDDM during 12.8 years of follow-up was examined in a prospective study of 7,735 middle-aged men drawn at random from general practice in 24 British towns. With the exclusion of men with missing hematocrit data and men with diabetes at screening, data were available for 7,193 men, in whom there were 187 new cases of NIDDM during follow-up. The risk of NIDDM increased significantly with increasing hematocrit levels. There was more than a fourfold increase in relative risk (RR) of diabetes among men with a hematocrit of > or = 48% relative to those with a hematocrit <42%, adjusted for age and BMI (RR 4.5; 95% CI 2.5-6.3). On further adjustment for predictors of NIDDM with which hematocrit is correlated, there remained a strong linear association with the risk of diabetes. There was a nearly fourfold increased risk of NIDDM in the highest relative to the lowest hematocrit group in the fully adjusted proportional hazard model (RR 3.6; 95% CI 1.7-7.6). The strong positive association between hematocrit level and risk of diabetes was seen even after exclusion of men with preexisting ischemic heart disease. The findings suggest that a raised hematocrit level, which is a major determinant of whole blood viscosity, should be added to the cluster of risk factors that link NIDDM with atheromatous, vascular disease.

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.

In order to study the plasminogen activator inhibitor activity (PAI-1) in subjects at different risk of non-insulin-dependent diabetes and ischaemic heart disease we examined 89 subjects with diet controlled NIDDM (49 Caucasian, 40 Asian), 29 with impaired glucose tolerance (IGT) (13 Caucasian, 16 Asian), and 149 with normal glucose tolerance (67 Caucasian, 82 Asian). Diabetes was diagnosed by WHO criteria and highly specific, monoclonal antibody-based assays were used to measure insulin, intact proinsulin, and des 31,32 proinsulin. Subjects with NIDDM were significantly more obese, had more central distribution of obesity, higher fasting plasma specific insulin concentrations (NIDDM median 74 pmol l-1 vs IGT 41 pmol l-1, p < 0.01 and vs normals 34 pmol l-1, p < 0.001) and higher PAI-1 activity than normals and those with IGT (NIDDM 23.0 +/- 6.9 vs IGT 16.8 +/- 5.0, p < 0.001 and vs normals 17.1 +/- 6.9 AU ml-1, p < 0.001). However, PAI-1 activity was not significantly different between Asian and Caucasian normals (17.5 +/- 7.3 vs 16.5 +/- 6.4 AU ml-1, p = ns) and diabetic (22.8 +/- 7.3 vs 23.1 +/- 6.6 AU ml-1, p = ns) subjects. In addition to relationships with obesity and plasma triglyceride, PAI-1 activity, after controlling for age, sex, body mass index, and waist-hip ratio, was related to fasting insulin (partial r = 0.22, p < 0.001), intact proinsulin (partial r = 0.36, p < 0.001), and des 31,32 proinsulin concentrations (partial r = 0.33, p < 0.001) as measured by highly specific assays. The association of PAI-1 with diabetes was weakened but remained statistically significant (p = 0.042) after controlling for age, sex, ethnicity, obesity, plasma triglyceride, and all insulin-like molecules. We conclude that, although PAI-1 activity is raised in subjects with diet-treated NIDDM, it is normal in subjects with IGT and non-diabetic Asians, populations at high risk of NIDDM and ischaemic heart disease. Raised PAI-1 activity may play an important role in the pathogenesis of macrovascular disease in subjects with NIDDM, but is unlikely to explain excess risk of ischaemic heart disease in Asians and those with impaired glucose tolerance.

The prevalence of vascular complications was assessed in 726 South Indian non-insulin dependent diabetes mellitus (NIDDM) patients with over 25 years' duration of diabetes. Retinopathy was detected in 52.0% of patients which included 41.7% with non-proliferative and 10.3% with proliferative diabetic retinopathy. Nephropathy was present in 12.7% and neuropathy in 69.8% of patients. While 32.8% of patients had ischaemic heart disease, the prevalence of peripheral vascular disease was only 15.4%. Multivariate logistic regression analyses showed that serum creatinine was associated with retinopathy, creatinine and post-prandial plasma glucose with nephropathy and post-prandial plasma glucose and age with neuropathy. This is one of the first reports on vascular complications in long-term diabetes from the Indian sub-continent.
