BACKGROUND
Glycated hemoglobin (HbA1c) levels represent a 2~3 month average of blood glucose concentration. The use of HbA1c as a diagnostic tool for diabetes is gaining interest. Therefore, we determined the cutoff point of HbA1c for predicting abnormal glucose tolerance status in non-diabetic Korean subjects. METHODS: We analyzed the data from 1,482 subjects without diabetes mellitus in whom a 75-g oral glucose tolerance test (OGTT) was performed due to suspected abnormal glucose tolerance. We obtained an HbA1c cutoff point for predicting diabetes using Receiver Operating Characteristic (ROC) curve analysis. RESULTS: A cut-off point of 5.95% HbA1c yielded sensitivity of 60.8% and specificity of 85.6%, respectively, for predicting diabetes. There was a difference in HbA1c cut-off value between men and women, 5.85% and 6.05%, respectively. CONCLUSION: To use the cut-off point of 5.95% HbA1c for predicting undiagnosed diabetes in Koreans may be reliable. However, studies of different ethnic groups have reported disparate HbA1c cut-off points. Thus, ethnicity, age, gender, and population prevalence of diabetes are important factors to consider in using elevated HbA1c value as a tool to diagnose diabetes.

BACKGROUND
A recently discovered adipokine, retinol-binding protein-4 (RBP-4), is reportedly associated with insulin resistance and metabolic syndrome. This study was performed to analyze the relationship between serum RBP-4 levels and coronary artery disease (CAD) in Korean adults. METHODS: In 235 subjects (mean age 58 years) in whom coronary artery angiograms were performed due to complaints of chest pain, serum RBP-4 levels were measured by enzyme-linked immunosorbent assay. Coronary artery angiograms were performed in all subjects and the severity of CAD was assessed by the number of stenotic vessels. The presence of metabolic syndrome was defined by AHA/NHLBI criteria with body mass index substituted for waist circumference. RESULTS: Coronary angiogram showed that 101 subjects (43%) had normal coronary vessel, 82 subjects (34.9%) had 1-vessel disease, 31 subjects (13.2%) had 2-vessel disease and 21 subjects (8.9%) had 3-vessel disease. Subjects with coronary artery stenosis showed a higher mean age (60.5 +/- 10.0 years), fasting glucose (123.3 mg +/- 45.0 mg/dL) and lower mean value for high-density lipoprotein cholesterol (HDL-C) level (49.0 +/- 13.2 mg/dL), although serum RBP-4 levels were not significantly different between those with and without CAD. Mean age and fasting glucose level increased significantly as the number of stenotic vessels increased, although serum RBP4 level showed no significant differences among the different groups. Among the metabolic parameters, only serum triglyceride levels showed a significant correlation with serum RBP-4 levels. CONCLUSION: There was no difference in mean serum RBP-4 levels between subjects with or without coronary artery disease in Korean adults. Further studies are warranted to draw a clear conclusion on the effect of RBP-4 on atherosclerosis.

Abstract PDF

BACKGROUND
Insulin resistance and progressive pancreatic beta cell dysfunction have been identified as the two fundamental features in the type 2 diabetes. Homeostasis model assessment (HOMA), based on plasma levels of fasting glucose and insulin, has been widely validated and applied for quantifying insulin resistance and secretion. This study was performed to assess the predictive value of HOMA indices for future diabetes risk. METHODS: In 14,976 Korean men, in which medical check-up was performed both in 2002 and 2006 in a university hospital health promotion center in Seoul, Korea, prospective assessment for diabetes risk was assessed. At baseline, anthropometric measurements were done and fasting glucose, insulin, lipid profiles were measured. HOMA-insulin resistance (HOMA-IR) and beta cell function (HOMA beta-cell) were calculated from fasting glucose and insulin levels. RESULTS: After 4 years, 286 subjects (1.9%) were newly diagnosed as diabetes mellitus. These patients (mean age 40.3 years) were age-matched with 632 control subjects (mean age 39.8 years) and diabetes risk was assessed with HOMA indices. Among the parameters, body mass index, fasting glucose and HOMA beta-cell were the significant determinants for future diabetes risk. When the subjects were divided into two groups according to the baseline median values of HOMA-IR and HOMA beta-cell, and assessed jointly, those with the low HOMA beta-cell and high HOMA-IR showed the highest risk for future diabetes (RR 39.065, 95% CI 11.736~130.035, P < 0.01). The subjects with low baseline HOMA beta-cell showed higher RR for diabetes than those with high baseline HOMA-IR (4.413 vs. 3.379, P = 0.018, P = 0.051). CONCLUSION: High HOMA-IR and low HOMA beta-cell were associated with the highest risk for future diabetes in this prospective study of Korean male subjects. These data suggest the value of HOMA indices for diabetes risk in epidemiologic studies in Asian subjects.

Abstract PDF

BACKGROUND
We compared the prevalences of two criteria of metabolic syndrome, that is, American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) and International Diabetes Federation (IDF), in Korean male adults and compared the predictability of insulin resistance and future cardiovascular diseases using Framingham Risk Score. METHODS: In total 23,467 male adults (mean age 43.3 years) who participated in medical check-up in 2005, the prevalences of metabolic syndrome according to AHA/NHLBI and IDF criteria and the presence of insulin resistance, defined by the highest quartile of Homeostasis Model Assessment of insulin resistance index (HOMA-IR), were compared. The relative risk (calculated risk/average risk) for 10-year risk for coronary artery disease (CHD) assessed by Framingham Risk Score were compared. RESULTS: 5.8% of the subjects had diabetes mellitus. 20.7% and 13.2%of the subjects had metabolic syndrome defined by AHA/NHLBI and IDF criteria, and the two criteria showed high agreement with kappa value of 0.737 (P < 0.01). More subjects in IDF-defined group had insulin resistance compared with AHA/NHLBI definition (59.8 vs. 54%, P < 0.01). The odds ratio for increased relative risk (> 1.0) for 10-year CHD were higher in AHA/NHLBI-defined subjects compared with IDF-defined subject (3.295 vs. 3.082). The Kappa values for the analysis of agreement between each criteria and prediction of insulin resistance or cardiovascular disease risk, were too low for comparison. CONCLUSION: In Korean males, the prevalence for metabolic syndrome defined by AHA/NHLBI criteria was higher than those defined by IDF criteria. IDF criteria detected more subjects with insulin resistance, but didn't have better predictability for CHD compared with AHA/NHLBI criteria.

Abstract PDF: BACKGROUND
PPAR-gamma, a member of nuclear family, which is involved in the differentiation of adipose tissue, is reported to be associated in the pathogenesis of type 2 diabetes mellitus, insulin resistance and atherosclerosis. We conducted a research to see whether the prevalence of coronary artery disease is associated with Pro12Ala polymorphism in exon B of PPAR-gamma in Korean adults. METHODS: The study was conducted in 161 subjects (97 males, 64 females, mean age 57 year old) who underwent coronary angiogram due to chest pain. We assessed cardiovascular risk factors in all subjects, such as blood pressure, body mass index (BMI), fasting blood sugar and serum lipid profiles. Subjects were divided into four groups as normal, 1-vessel, 2-vessel and 3-vessel disease according to the number of stenosed coronary arteries. Genotypings of Pro12Ala polymorphism were done with Real-time polymerase chain reaction. RESULTS: Allelic frequency for proline was 0.957 and 0.043 for alanine, and they were in compliance with Hardy-Weinberg equilibrium (P = 0.85). 79 subjects (43.5%) had normal coronary artery, 52 subjects (31%), 1-vessel disease, 24 subjects (14.9%), 2-vessel disease and 15 subjects (9.3%), 3-vessel disease. When the cardiovascular risk factors were compared among these four groups, there were no meaningful differences except the age and high-density lipoprotein cholesterol levels, which were lost after adjustment for age and BMI. There were no significant differences in the prevalence or severity of coronary artery diseases according to the different genotypes of Pro12Ala polymorphism. CONCLUSIONS: There was no significantassociation between Pro12Ala polymorphism in exon B of PPAR-gamma and prevalence or severity of coronary artery disease in Korean adults. It is considered that further studies on the correlation between Pro12Ala polymorphism and coronary artery disease should be carried out in larger Korean population in the future

Abstract PDF: BACKGROUND
Interleukin(IL)-6 is a cytokine that is produced from immune cells and adipose tissue. It is thought to be a factor to explain the link between insulin resistance and inflammation, and it is also thought to be involved in glucose metabolism and lipid metabolism. We observed the frequency of the G174C polymorphism in the IL-6 gene promoter region in Korean women and we investigated the association of fasting glucose, insulin resistance indices and metabolic syndrome. METHODS: Measurements of the blood pressure, body fat, fasting glucose, insulin, lipid profiles and anthropometric measurements were done for 268 Korean women(mean age 51.4yrs, range 37~73yrs). Homeostasis model assessement(HOMA) and the quantitative insulin sensitivity check index(QUICKI) were calculated and the presence of metabolic syndrome was assessed according to ATP III criteria. Genotyping was done with the PCRRFLP method on the blood samples of the participants. RESULTS: The allele frequencies were 0.965 for the G allele and 0.035 for the C allele, and they were in Hardy-Weinberg equilibrium(P=0.50). The fasting insulin level and HOMA were significantly higher and the QUICKI was significantly lower in the C allele carriers compared with non-carriers. Although the prevalence of metabolic syndrome was not significantly different according to the different genotypes, among the individual components, the prevalence of hypertriglyceridemia was significantly higher in the C allele carriers compared with the non-carriers. There were no differences in the prevalence of normoglycemia, fasting hyperglycemia and provisional diabetes according to the different genotypes. CONCLUSION: The G174C polymorphism in The IL-6 promoter region was not frequently observed in Korean women. The insulin resistance indices were higher in the C allele carriers compared with the non-carriers. Although the prevalence of metabolic syndrome was not associated with the polymorphism, the prevalence of hypertriglyceridemia was higher in The C allele carriers, suggesting that it is possibile for candidate gene of insulin resistance

Left Ventricular Mass Index Increases in Proportion to the Urinary Microalbumin Excretion Rate in Type 2 Diabetes.: Seung Ha Park, Won Young Lee, Sun Woo Kim; Korean Diabetes J. 2002;26(6):500-508. Published online December 1, 2002

Abstract PDF: BACKGROUND
In type 2 diabetes, microalbuminuria is an early marker of the atherosclerotic process and of endothelial dysfunction. It has also been shown to be related with the prevalence and morbidity of renal and cardiovascular diseases, and is associated with other risk factors of vascular damage. Left ventricular hypertrophy (LVH) has long been established as a major independent marker of future cardiovascular morbidity and mortality, depending on the body mass and blood pressure load. In order to clarify any association between the urinary microalbumin excretion rate (UAER) and the left ventricular mass index (LVMI), which may explain the observed poor prognosis in these patients, we analysed the clinical characteristics and laboratory findings data of type 2 diabetes. METHODS: We conducted a cross-sectional study of 48 patients with type 2 diabetes, who had been echocardiographically assessed and their 24-h urine collection analyzed for UAER, and the patients with clinical evidence of heart and renal diseases were excluded. The patients were divided into two groups according to their mean LVMI value (Low LVMI group: LVMI <97 g/m2, n=26; High LVMI group: LVMI >or=97 g/m2, n=22). RESULTS: The UAER, and systolic and diastolic blood pressures, were higher in the High LVMI group, but age, sex, body mass index (BMI) and duration of diabetes were similar in both group. The correlation of UAER and systolic blood pressure with LVMI remained significant, even after a multiple regression analysis (p=0.042, p=0.01 respectively). CONCLUSION: The significant relationship between the UAER and LVMI was independent of blood pressure, age, sex, BMI, duration of diabetes and other cardiovascular risk factors in type 2 diabetes. Therefore, an increased UAER may play an important role in the development of LVH.

Relationship between C-peptide, Metabolic Control and Chronic Complications in Type 2 Diabetes.: Jeung Mook Kang, Won Young Lee, Ji Youn Kim, Jung Won Yun, Sun Woo Kim; Korean Diabetes J. 2002;26(6):490-499. Published online December 1, 2002

Abstract PDF: BACKGROUND
Type 2 diabetes mellitus is a heterogeneous disease characterized by variable degrees of insulin resistance, impaired insulin secretion and increased glucose production. As the decline of beta-cell function in type 2 diabetes is very slow, the relationship between the insulin secretory capacity, the degree of metabolic control and chronic complications is still unclear. The determination of plasma C-peptide allows for the assessment of the endogenous insulin production, even in the presence of exogenous insulin administration. The aim of this study was to evaluate the relationship between the serum C-peptide level and metabolic parameters, and the complications in type 2 diabetes. METHOD: The clinical characteristics and laboratory findings, such as lipid profile, fasting plasma glucose, HbA1C and uric acid, were evaluated, and their relationships with chronic complications analyzed. We measured the serum C-peptide level by radioimmunoassay (RIA) in 384 type 2 diabetes mellitus patients. The patients were divided into quartile groups according to their fasting C-peptide levels (quartile 1: <1.73 ng/mL, n=95; quartile 2:>or=1.73 ng/mL and <2.38 ng/mL, n=95; quartile 3:>or=2.38 ng/mL and <3.18 ng/mL, n=98; quartile 4:>or=3.18 ng/mL, n=96). RESULTS: Patients in the lowest C-peptide quartile showed significantly higher durations of diabetes, HbA1C and postprandial plasma glucose values, and HDL-cholesterol. Conversely, the BMI, systolic blood pressure, total cholesterol and triglyceride were significantly higher in the highest C-peptide quartile. The prevalence of diabetic retinopathy and urinary protein excretion were higher in lowest quartile, and the diastolic blood pressure was highest in the upper quartile, but these were not statistically significant. The associations between C-peptide, and the duration of diabetes, BMI, total cholesterol, triglyceride, HDL cholesterol, postprandial 2 plasma glucose and systolic blood pressure remained significant, even after multiple adjustments. CONCLUSION: In type 2 diabetes, higher C-peptide levels are associated with a component of metabolic syndrome and lower C-peptide levels due to decreased cell reserves, associated with hyperglycemia and microvascular complications
