The incidence of CAD was 38.7% among all the patients. Patients with CAD had significantly low levels of high-density lipoprotein cholesterol (HDL-C) as compared with patients without CAD (45 ± 9 vs 51 ± 13 mg/dL; P = .009). Multivariate analysis showed that only low HDL-C levels were associated with the presence of CAD (adjusted odds ratio, 0.946; 95% confidence interval, 0.911-0.983; P = .004). The optimal cutoff level of HDL-C to predict CAD was 47.50 mg/dL. The CAD is common in patients with aortic aneurysms, and low levels of HDL-C are independently associated with the presence of CAD.

Incident HTN over a 7-year follow-up was assessed among 1,375 first-degree non-diabetic and non-hypertensive relatives of consecutive patients with type 2 diabetes who were 30 to 70 years of age. HTN was defined as a blood pressure reading ≥140/90 mm Hg or the use of antihypertensive medications. We examined the incidence of HTN across VAI quintiles and four groups defined according to baseline fasting serum triglyceride (TG) levels and waist circumference (WC). The VAI and the HTGW phenotype at baseline were related to an increased risk for HTN. In comparison with the lowest VAI quintile, the highest VAI quintile showed a significant associated with HTN in an age- and gender-adjusted model (odds ratio [OR], 1.65; 95% confidence interval [CI], 1.07 to 2.5...

The incidence of CAD was 38.7% among all the patients. Patients with CAD had significantly low levels of high-density lipoprotein cholesterol (HDL-C) as compared with patients without CAD (45 ± 9 vs 51 ± 13 mg/dL; P = .009). Multivariate analysis showed that only low HDL-C levels were associated with the presence of CAD (adjusted odds ratio, 0.946; 95% confidence interval, 0.911-0.983; P = .004). The optimal cutoff level of HDL-C to predict CAD was 47.50 mg/dL. The CAD is common in patients with aortic aneurysms, and low levels of HDL-C are independently associated with the presence of CAD.

At baseline and at follow-ups, participants underwent a standard 75 g 2-hour oral glucose tolerance test (OGTT). Prediction of progression to type 2 diabetes was assessed by using area under the receiver-operating characteristic (ROC) curves based upon measurement of FPG, post-load glucose values and HbA1c. The incidence of type 2 diabetes was 33.9 per 1000 person-years in men and 48.6 in women. The incidence rates were 4.6, 50.7, and 99.7 per 1000 person-years in FDR with normal glucose tolerance, impaired fasting glucose and impaired glucose tolerance respectively. ...

After the initial selection in 1999, the patients were followed for five years. Mean and standard deviation (SD) of age and duration of diabetes was 57.4 (9.5) and 10.2 (4.7) years, respectively. BMI, blood pressure, fasting plasma glucose, HbA1c, serum lipids and serum creatinine were measured and re-examined every three months. 24-h urinary albumin excretion was measured and reviewed annually. Microalbuminuria was diagnosed when at least two measurements indicated the excretion of more than 30 mg albumin in 24-h urinary samples. During 5-year follow up, 176 patients developed microalbuminuria, giving an incidence rate of 82.3/1000 ...

A total of 222 FDR of consecutive patients with T2DM aged between 35 and 55 years and 202 healthy individuals with no family history of diabetes were investigated for NAFLD. Fatty liver was diagnosed by ultrasonography using standard criteria. Height, weight, fasting glucose, alanine aminotransferase (ALT), total cholesterol and triglyceride were determined by routine laboratory methods. Compared to subjects with no family history of diabetes, the age and sex adjusted odds ratio (OR) of NAFLD was 1.83 (95% CI: 1.11-3.03) for FDR of patients with T2DM. After further adjusting for BMI, fasting glucose, ALT, asparate aminotransferase (AST), triglyceride and cholesterol, the multivariate OR of prevalent NAFLD in FDR of patients with T2DM compared with individuals with no family ...

A cross-sectional study of FDR of type 2 diabetes patients was conducted between 2003 and 2005. A total of 2,368 FDR of type 2 diabetes outpatients aged 30-60 years (614 men and 1754 women) from Isfahan Endocrine and Metabolism Research Center (Iran) were examined. All subjects underwent a standard 75 g 2-h oral glucose tolerance test (OGTT). IGT, IFG and type 2 diabetes were diagnosed according to the criteria of the American Diabetes Association (ADA). The mean (SD) age of participants was 43.1 (6.9) years. The prevalence of type 2 diabetes, IGT and IFG were 10.3% (95% CI: 9.1-11.5), 19.5% (17.9-21.1) and 17.3% (15.8-18.8) respectively. The prevalence rates were significantly higher than those reported for a control population of the same age (type 2 diabetes, 6.0% (95% CI: 5....

We investigated the prevalence of hypogonadism in Iranian type 2 diabetic men. Total testosterone (TT) and sex hormone binding globulin (SHBG) concentrations were measured in 247 diabetic men >30 years who had symptoms of androgen deficiency, according to ADAMs questionnaire. The correlation between some parameters and total, free and bioavailable testosterone levels was determined using Pearson correlation coefficient. Free and bioavailable testosterone were calculated by electronic calculator. Four patients were excluded because of high testosterone level, due to unreported androgen use. Overt hypogonadism was defined as total testosterone ≤8 nmol/l or calculated bioavailable testosterone (cBT)≤2.5 nmol/l and borderline hypogonadism was considered as TT 8-12 nmol/l or cBT 2.5-4nmol/l. The mean and SD of age was 59 (9.3) years. The mean TT, calculated free testosterone (cFT), and cBT and SHBG l...
