AbstractAbstract PDF
The oral glucose tolerance test (OGTT) for detection of diabetes is difficult to perform in clinical settings. The aim of this study is to evaluate the performance of a more practical detection test, combined fasting plasma glucose (FPG) and glycosylated hemoglobin (HbA1c), as a predictor of diabetes mellitus (DM) in a Korean sample. METHODS: We examined 2,045 (M = 1,276, mean age = 47.8 +/- 9.0 yrs) medical check-up program participants between January 2002 to December 2003. FPG, HbA1c and a number of other biochemical tests were performed at baseline and four after years after initial screening. Patients who originally presented with diabetes were excluded. The characteristics of newly-diagnosed DM patients and non-diabetic patients were compared. RESULTS: The incidence of newly diagnosed diabetes was 1.6% (32/2,045) after four years of follow up. The subjects in the DM group were older, had higher levels of SBP, DBP, FPG, HbA1c, triglyceride, HDL cholesterol, GGT and LDH (P < 0.05). In multivariate logistic regression analysis, FPG (odds ratio [OR] 1.124) and HbA1c (OR 4.794) were significantly correlated with onset of diabetes (P < 0.05). The interaction parameter between FPG and HbA1c was more than 1.0, indicating that the two effects are synergistic. The predictive cut-off values of HbA1c and FPG were 5.35% (area under curve [AUC] = 0.944) and 102.5 mg/dL (AUC = 0.930), respectively. CONCLUSION: The combination of HbA1c above 5.35% and FPG above 102.5 mg/dL predicted the onset of diabetes in a Korean sample. These results suggest that the combination of FPG and HbA1c may be useful for predicting progression to type 2 diabetes in east Asians.

AbstractAbstract PDF
Lipid oxidation and formation of oxygen radicals have been identified to be the important factors of atherogenesis. Because bilirubin, a potent physiological antioxidant inhibits lipid oxidation, it is suggested that low serum concentrations of bilirubin is associated with atherosclerosis. The aim of this study was to evaluate the relationship between bilirubin levels and coronary atherosclerosis. METHODS: The coronary calcium score (CCS) of 172 subjects (male 63, mean age 60.5 +/- 1.0) with type 2 diabetes were evaluated in Yeungnam University Hospital between January 2005 and February 2007. The subjects were divided into two groups with CCS 10 as the cut off. RESULTS: Higher CCS was significantly associated with lower bilirubin (P < 0.05), but after adjusted with age, no longer correlation were seen (P = 0.121). To determine the relationship between subclinical coronary atherosclerosis and bilirubin, the subjects with previous history of cardiovascular disease were excluded. In 138 subjects (male 54, mean age 58.4 +/- 1.1), higher CCS was significantly associated with lower levels of bilirubin. After adjusted with age, duration of diabetes, and history of hypertension, CCS was also inversely related with bilirubin (P < 0.05). CONCLUSION: These results suggest that lower levels of bilirubin might be considered as a risk factor of coronary artery disease, especially in type 2 diabetics without cardiovascular disease.

AbstractAbstract PDF
Diabetic retinopathy is a leading cause of adult blindness. Some patients show early development and progression of diabetic retinopathy despite of apparently good glycemic control. This is suggesting the involvement of other contributing factors. Recent studies have shown that retinopathy and GAD autoantibody (GADA) show an inverse relationship immunologically. This study is designed to investigate the clinical manifestation of diabetes who are positive for GADA and the relationship between GADA and diabetic retinopathy. METHODS: Type 1 diabetic patients & LADA patients who had visited Yeungnam university Medical Center from 1988 to 2005 were involved. We reviewed the pathologic and laboratory records of these patients and investigated the development of diabetic microvascular complications. RESULTS: Compared with patients who had GADA negative diabetes, patients with GADA positive diabetes had lower prevalence of diabetic retinopathy (GADA negative subject: 25.8% vs. GADA positive subject: 9.6%, P < 0.05). CONCLUSION: We confirmed that diabetic retinopathy and GADA showed an inverse relationship. It seems quite probable that GADA may contribute to the prevention of retinopathy. Further research should be needed concerning the effect of GADA on diabetic retinopathy.

AbstractAbstract PDF
Hyperglycemia is a well-recognized pathogenic factor of long term complications in diabetes mellitus and hyperglycemia also generates reactive oxygen species (ROS) in beta cells when ROS accumulate in excess for prolonged periods of time, they cause chronic oxidative stress and adverse effects. Unfortunately, the islet contacts low capacity of endogenous antioxidant effects. But, gamma-glutamylcysteine synthetase (gamma-GCS), the rate-limiting enzyme for glutathione synthesis, is well represented in islets. METHODS: This study is to evaluate the changes in the activity of gamma-GCS, glutathione in beta-cells exposed to high glucose, in pancreatic tissue of OLETF (Otsuka Long Evans Tokushima Fatty) and LETO (Long-Evans Tokushima Otsuka) rats, in leukocytes from patients with Korean type 2 DM (T2DM) and to disclose the effects of high blood glucose on this impairment in patients with T2DM. We divided our patients into 3 groups by HbA1c (controls: n = 20, well controls diabetes: n=24, poorly controlled diabetes: n = 36). RESULTS: We observed that decreased glutathione level, gamma-GCS expression, glucose-stimulated (GSIS) and increased intracellular peroxide level in the INS-1 cells exposed to 30 mM glucose condition. Also decreased glutathione level at erythrocytes, gamma-GCS expression at leukocytes and increased oxidized LDL, MDA (malondialdehyde) level at plasma from patients with T2DM compared to controls (esp, poorly controlled patients). CONCLUSION: These results suggest that insufficient antioxidant defenses by the glutathione pathway may be one of the factors responsible for development of complications in T2DM.

AbstractAbstract PDF
BACKGOUND: Chronic hyperglycemia is the proximate cause of many complications of diabetes. The beta cells in type 2 diabetes are also adversely affected by chronic hyperglycemia, with this relentless deterioration in cell function, due to constant exposure to supraphysiologic concentrations of glucose, is termed glucose toxicity; however, the mechanism of glucose toxicity is uncertain. The purpose of this study was to determine whether prolonged exposure of pancreatic islets to supraphysiologic glucose concentration disrupts the intracellular balance between reactive oxygen species(ROS) and antioxidant enzyme; thereby, causing defective insulin secretion. METHODS: HIT-T15 cells were treated with H2O2(20, 50 and 100micrometer) directly added to the culture media, and then intracellular peroxide and insulin mRNA were then measured. The effects of H2O2 on the total peroxide level and insulin secretion were also examined. Isolated pancreatic islet cells from Wistar and 2 beta cell lines (INS-1, HIT-T15) were cultured in either a glucose or ribose (5.6, 11.1, 22.2, 30 and 50mM) containing culture media for 72hours. The intracellular peroxide was measured using flow cytometry and glucose stimulated insulin secretion(GSIS). RESULTS: The intracellular peroxide levels due to H2O2 in HIT-T15 cells were higher with a high concentration of H2O2, and the insulin mRNA in HIT-T15 cells decreased when the cells are treated with a high concentration H2O2. The insulin mRNA of the HIT-T15 cells cultured in a high concentration of ribose was lower than of those cultured in a low concentration of glucose. INS-1, HIT-T15 and rat islet cells, cultured for 72 hours, had progressively greater peroxide levels with higher concentrations of both glucose and ribose. The GSIS in the cells cultured in high concentrations of both glucose and ribose were decreased. CONCLUSION: These results suggest only one potential central mechanism for glucose toxicity in beta cells, this being the formation of excess ROS.
