BACKGROUND
With the extension of human life span, the prevalence of diabetes in elderly population is increasing. The glycemic control is also important in elderly diabetics because the life expectancy in elderly is steadily increased. In this study, we investigated the role of family support on glycemic control in elderly type diabetic patients. METHODS: This study was conducted with 126 type 2 diabetic patients over 60 years of age who were enrolled between March and December, 2005. The data for glycemic control, family characteristics, and family support were collected by structured questionnaire, personal interview, and medical record review. We used total supportive index scores to evaluate family support. We evaluated the relationship between family support and glycemic control. RESULTS: Fasting plasma glucose was positively correlated with duration of diabetes (r = 0.277, P = 0.003). Postprandial 2 hour plasma glucose was negatively correlated with monthly incomes (r = -0.357, P = 0.002), assessment support (r = -0.201, P = 0.029). Hemoglobin A1c was positively correlated with duration with diabetes (r = 0.294, P = 0.002) and insulin use (r = 0.259, P = 0.004), but it was negatively correlated with diabetic self-management education (r = -0.190, P = 0.036). Adjusted for age, sex, duration of diabetes, and monthly incomes, there were no significant associations between glycemic control and family support. CONCLUSION: In this study, there were no significant associations between glycemic control and family support. More large prospective studies will be followed to exactly evaluate the role of family support in diabetic patients.

BACKGROUND
Previous studies have reported that type 2 diabetes is associated with the increased blood concentrations of markers for the acute phase response, such as C-reactive protein (CRP), serum sialic acid and fibrinogen. The purpose of this study was to verify whether the pro-inflammatory cytokine- induced acute-phase response is a major pathogenic mechanism for type 2 diabetes in elderly Korean women. METHODS: We randomly selected a total of 232 non-smoking and non-diabetic female subjects among a total of 1,737 elderly subjects aged over 60 years who had participated in a population based study in Seoul, Korea (SWS Study 1999). We compared concentrations of pro-inflammatory cytokines, such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha), as well as the acute-phase reactant C-reactive protein (CRP), between the subjects with normal glucose tolerance (NGT) and the subjects with impaired glucose tolerance (IGT). RESULTS: The IGT group showed higher serum high-sensitivity CRP (hs-CRP) concentrations than did the NGT group (the median was 1.2 versus 0.9, respectively, p<0.05). Moreover, a close relationship between serum hs-CRP concentrations and many components of the metabolic syndrome was found. However, serum concentrations of pro-inflammatory cytokines, IL-6 and TNF-alpha were not increasedin the IGT group, and they were not closely correlated with the components of metabolic syndrome. Multiple regression analysis using a stepwise selection method showed that the white blood cell counts, body mass index (BMI), fasting insulin, post-load 2h glucose, hematocrit and LDL cholesterol were associated with hs-CRP. CONCLUSIONS: The present study confirms the relationship between C-reactive protein, impaired glucose tolerance and metabolic syndrome in elderly Korean women.

BACKGROUND
VEGF(vascular endothelial growth factor) has been implicated in the pathogenesis of neovascularization and endothelial dysfunction in diabetes mellitus. However, its precise role in diabetic nephropathy is still unknown. Our aims were to determine whether alterations of plasma and urinary VEGF levels were related to diabetic microvascular complications, especially nephropathy in type 2 diabetic patients. METHODS: 107 type 2 diabetic patients, without non-diabetic kidney diseases, and 47 healthy control subjects were studied. The urinary albumin excretion was defined as the albumin-to-creatinine ratio(ACR) in 24 hour urine samples. The study subjects were divided into four groups: a nondiabetic healthy control group(n=47), a normoalbuminuric diabetic group(ACR <30mug/mg, n=37), a microalbuminuric diabetic group(ACR 30~299mug/mg, n=37) and an overt proteinuric diabetic group(ACR=300mug/mg, n=33). The plasma and urinary VEGF levels were measured in these subjects by enzyme-linked immunosorbent assays. RESULTS: 1) The urinary VEGF concentrations were significantly higher in the diabetic groups than in the controls, even in the normoalbuminuric stage(log VEGF/Cr, normoalbuminuria; 4.33+/-1.06 vs. control; 3.53+/-0.79, p=0.009). The levels of urinary VEGF excretions increased with advancing diabetic nephropathy stage. 2) The plasma and urinary VEGF levels were higher in the hypertensive diabetic than the normotensive diabetic patients. 3) In the diabetic patients, the level of plasma VEGF was positively correlated with the BUN(r=0.398, p=0.039) and urinary ACR (r=0.251, p=0.044). The level of urinary VEGF was positively correlated with the urinary ACR(r=0.645, p<0.001), and creatinine(r=0.336, p=0.009), but negatively correlated with the level of serum albumin(r=-0.557, p<0.001). Both the levels of urinary VEGF and serum creatinine were independently correlated with the urinary ACR. CONCLUSIONS: The excretion of urinary VEGF increased at a relatively earlier stage in diabetic nephropathy and was significantly correlated with the excretion of urinary albumin. These results suggested the possibility of urinary VEGF as a sensitive marker or the detection of diabetic nephropathy and in predicting disease progression.

BACKGROUND
The clustering of cardiovascular risk factors is known as insulin resistance syndrome. Hyperinsulinemia has been suggested as a cardiovascular risk factor due to the capacity of insulin to induce vascular endothelial proliferation and atherosclerosis. Insulin also has been shown to stimulate erythroid colony formation independently of erythropoietin. WBC count is one of the major components of the inflammatory process and is increased by IL-6, which is high in those with features of insulin resistance. In this study, we investigated whether insulin resistance affects hematological parameters. METHODS: In this study, 1,314, randomly selected, non-diabetic, elderly subjects over 60 years living in the southwest area of Seoul were recruited. Subjects underwent 75 g OGTT and careful physical examinations during evaluation, and were interviewed using a standardized questionnaire. Biochemical data and hematologic parameters were also measured. Insulin resistance was calculated by HOMA (homeostasis model assessment) method. Analysis of variance, Duncan's multiple comparisons and multiple linear regression analysis were carried out. RESULTS: In the male non-smoking group we found a correlation between insulin resistance and hemoglobin concentration (r=0.20, p=0.0186). In the female non- smoking group we found correlations between insulin resistance and both hemoglobin concentration (r=0.10, p=0.0017) and white blood cell (WBC) count (r=0.15, p=0.001). Hemoglobin concentration and WBC count were also correlated with BMI, systolic and diastolic blood pressure, lipid profiles and fasting insulin levels in female non-smokers. In multiple regression analysis, using HOMA IR as a dependent variable, we found significance in the variables of hemoglobin concentration, WBC count, age, BMI and triglyceride level. CONCLUSION: Our study provided evidence for a relation between insulin resistance and hematological parameters such as hemoglobin concentration and WBC count in elderly Koreans. This suggests that increased hemoglobin level and WBC count could be considered as novel aspects of the met.
