- Background
Long-term durable glycemic control is a difficult goal in the management of type 2 diabetes mellitus (T2DM). We evaluated the factors associated with durable glycemic control in a real clinical setting.
MethodsWe retrospectively reviewed the medical records of 194 new-onset, drug-naïve patients with T2DM who were diagnosed between January 2011 and March 2013, and were followed up for >2 years. Glycemic durability was defined as the maintenance of optimal glycemic control (glycosylated hemoglobin [HbA1c] <7.0%) for 2 years without substitution or adding other glucose-lowering agents. Clinical factors and glycemic markers associated with glycemic durability were compared between two groups: a durability group and a non-durability group.
ResultsPatients in the durability group had a higher baseline body mass index (26.1 kg/m2 vs. 24.9 kg/m2) and lower HbA1c (8.6% vs. 9.7%) than the non-durability group. The initial choice of glucose-lowering agents was similar in both groups, except for insulin and sulfonylureas, which were more frequently prescribed in the non-durability group. In multiple logistic regression analyses, higher levels of education, physical activity, and homeostasis model assessment of β-cell function (HOMA-β) were associated with glycemic durability. Notably, lower HbA1c (<7.0%) at baseline and first follow-up were significantly associated with glycemic durability (adjusted odds ratio [OR], 7.48; 95% confidence interval [CI], 2.51 to 22.3) (adjusted OR, 9.27; 95% CI, 1.62 to 53.1, respectively), after adjusting for confounding variables including the types of glucose-lowering agents.
ConclusionEarly achievement of HbA1c level within the glycemic target was a determinant of long-term glycemic durability in new-onset T2DM, as were higher levels of education, physical activity, and HOMA-β.

- Background
Aldosterone antagonists are reported to have beneficial effects on diabetic nephropathy by effective blocking of the renin-angiotensin-aldosterone system. We investigated the renoprotective effect of the selective aldosterone receptor blocker eplerenone, the angiotensin converting enzyme inhibitor lisinopril, and combined eplerenone and lisinopril treatment in type 2 diabetic rats.
MethodsAnimals were divided into six groups as follows: Otsuka Long-Evans Tokushima Fatty (OLETF) rat control, OLETF rats treated with a low dose of eplerenone (50 mg/kg/day), OLETF rats treated with a high dose of eplerenone (200 mg/kg/day), OLETF rats treated with lisinopril (10 mg/kg/day), OLETF rats treated with a combination of both drugs (eplerenone 200 mg/kg/day and lisinopril 10 mg/kg/day), and obese non-diabetic Long-Evans Tokushima Otsuka rats for 26 weeks.
ResultsUrinary albumin excretion was significantly lower in the lisinopril group, but not in the eplerenone group. Urinary albumin excretion was decreased in the combination group than in the lisinopril group. Glomerulosclerosis and renal expression of type I and type IV collagen, plasminogen activator inhibitor-1, transforming growth factor-β1, connective tissue growth factor, and fibronectin mRNA were markedly decreased in the lisinopril, eplerenone, and combination groups.
ConclusionEplerenone and lisinopril combination showed additional benefits on type 2 diabetic nephropathy compared to monotherapy of each drug.

Abstract

- BACKGROUND
Cellular phones are extremely prevalent in modern society and they enable appropriate feedback mechanisms through real time monitoring and short message services regarding blood glucose levels. We investigated whether cellular phone-based telemedicine support system could improve blood glucose control in type 2 diabetes patients who were in inadequate glycemic control regardless of insulin therapy. METHODS: A randomized, controlled clinical trial was conducted involving 74 type 2 diabetic patients with suboptimal glycemic control (HbA1c levels > 7%) regardless of insulin therapy. The intervention (cellular phone-based telemedicine) group managed their blood glucose using a cellular phone for 3 months, while the control (self monitoring of blood glucose) group managed their blood glucose with a standard glucometer for the same period. RESULTS: Three months later, HbA1c levels were decreased in both groups. However, the decrease in the control group from 8.37% to 8.20% was only 0.20% (P = 0.152) which was not significant. In contrast, the intervention group had a significant reduction of 0.61% from 8.77% to 8.16% (P < 0.001). Moreover, among patients with a baseline > or = 8%, the patients in the intervention group showed a significant reduction of 0.81% from 9.16% to 8.34% (P < 0.001). CONCLUSION: HbA1c levels were significantly decreased in the cellular phone-based telemedicine group compared with the control group after 3 months. This study suggests that cellular phone-based telemedicine is helpful for better glucose control in type 2 diabetes patients who previously were unable to control glucose levels adequately with insulin therapy.

Abstract

- BACKGROUND
Diabetes is common among elderly, and low-income is associated with poor adherence to treatment and increased mortality. We evaluated whether comprehensive support using community networks improves glycemic control among low-income elderly patients with diabetes. METHODS: A total of 49 low-income elderly patients with type 2 diabetes, mean age 73 years, were enrolled. For 1 year, study subjects underwent various lifestyle modification programs provided by community networks. The biochemical data including glycemic markers and anthropometric data were obtained at the baseline and at the end of the study. Also, the patients were asked to complete a questionnaire about their quality of life, self-confidence and self-care behavior. RESULTS: After lifestyle modification program, overall changes of fasting plasma glucose, HbA1c, blood pressure, body weight, and other biochemical markers were not significantly different. In a subgroup analysis of 21 patients with poorly controlled diabetes (fasting glucose > 140 mg/dL or HbA1c > 7.5%), fasting plasma glucose was significantly reduced (P = 0.030). Among patients with baseline HbA1c level > or = 8%, HbA1c levels after intervention decreased from 9.33 +/- 1.07% to 8.27 +/- 1.15% (P = 0.092). The results of the questionnaires revealed significant increases in the scores of quality of life, self-confidence and self-care behavior (P < 0.05). CONCLUSION: Among low-income, elderly patients with type 2 diabetes, lifestyle modification through community networks showed no significant changes in glycemic control markers. More intensive and precise interventions using community networks are needed for the glycemic control of low-income, elderly patients with type 2 diabetes.

Abstract

- BACKGROUND
Telmisartan, used for the treatment of hypertension, has been shown to function as a partial agonist of peroxime proliferative activated receptor-nu (PPAR-nu). Theoretically, telmisartan which simultaneously blocks the angiotensin II receptor and activates PPAR-nu should be more effective in improving atherosclerotic surrogate markers than angiotensin II receptor blockers alone. Therefore, this pilot study was designed to evaluate and compare the efficacy of telmisartan and valsartan on plasma adiponectin levels and pulse wave velocity as a marker of arterial stiffness in patients with type 2 diabetes. METHODS: Thirty two patients with type 2 diabetes (mean duration 7.6 +/- 5.1 years) taking oral hypoglycemic agents were randomly assigned to receive telmisartan or valsartan for 12 weeks. RESULTS: Telmisartan and valsartan treatment significantly increased circulating adiponectin levels (P = 0.013 and P = 0.013, respectively) and reduced systolic (P = 0.001 and P = 0.002, respectively) and diastolic blood pressure (P = 0.001 and P < 0.001, respectively), and brachial-ankle PWV (P = 0.019 and P = 0.002, respectively), without significant differences between the two treatments. Before and after treatment, the fasting plasma glucose, interleukin-6, homeostasis model of assessment insulin resistance (HOMAIR) levels and lipid profile were unchanged in both treatment groups. CONCLUSION: Contrary to our expectation, telmisartan, even with its partial PPAR-nu activity, is not superior to valsartan in improving plasma adipocytokine levels and arterial stiffness in patients with type 2 diabetes. These data suggest that the partial PPAR-nu activity of telmisartan beyond valsartan may have less significant therapeutic implications than expected in treating patients with type 2 diabetes.

- BACKGROUND
Ischemia-induced neovascularization can cause the loss of vision in retinal disorders such as diabetic retinopathy. Recent studies have shown that the angiopoietin-Tie2 system is a major regulator of vascular integrity and it is involved in pathologic angiogenesis. However, its role in the pathophysiology of diabetic retinopathy is not yet known. We examined the regulation of the VEGF-angiopoietin-Tie2 system in both in vitro and in vivo studies to discover their possible role in diabetic retinopathy. METHODS: We investigated the effects of a well-known angiogenic stimulus, hypoxia(2% O2 concentration) and vascular endothelial growth factor(VEGF, 10 ng/mL) on the expression of the angiopoietin-Tie2 mRNA in bovine retinal pericytes(BRP) and bovine aortic endothelial cells(BAEC). We also examined the expressions of VEGF-angiopoietin-Tie2 mRNA in retinas of type 2 diabetic OLETF(Otsuka-Long-Evans-Tokushima-Fatty) rats at 30 and 50 weeks. We also investigated the effect of angiotensin II receptor type 1(AT1) antagonist on the VEGFangiopoietin-Tie2 expression. RESULTS: Hypoxia and VEGF treatment significantly increased angiopoietin-1(Ang1) mRNA expression in the BRPs. In contrast, the angiopoietin-2(Ang2) mRNA expression was unaltered in the BRPs treated with hypoxia and VEGF. Significant up-regulation of Tie2 mRNA expression was found and this lasted up to 12 h. However, using BAECs, we found that only the Ang2 expression responded to these two angiogenic stimuli. In OLETF rats, the Ang-Tie2 expression patterns were similar with those of the BAECs. Ang2 and VEGF mRNA were increased at 30 and 50 weeks for the OLETF rats, whereas the Ang1 expression was not changed. The up-regulation of Ang2 and VEGF was decreased with the losartan treatment, an AT1 receptor antagonist. Tie2 mRNA expression was increased only at 50 weeks and it did not show any decrement by the losartan treatment. CONCLUSION: Our data suggest that hypoxia and VEGF treatment differentially regulate the angiopoietin-Tie2 system in the two vascular cells. Ang2 and VEGF expressions were predominantly increased in type 2 diabetic rats, and the unopposed action of Ang2 with VEGF might be involved in the development of diabetic retinopathy. The renin-angiotensin system may be a potential mechanism for the up-regulated VEGF-Ang2 system

Abstract

- 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.

Abstract

- BACKGROUND
Several reports have recently suggested a positive correlation between components of metabolic syndrome (MS) or insulin resistance syndrome (IRS) and markers of the acute-phase response, including C-reactive protein (CRP). These results imply that MS and type 2 diabetes are the results of ongoing inflammatory process. Whether estrogen plays a beneficial role in preventing atherosclerosis has been a matter of controversy. The objective of this study was to evaluate the relationship between the serum levels of estradiol (E2) and the components of the MS and CRP in nondiabetic subjects of Ansan Health Study (AHS). METHODS: Eight-hundred and ninety-one healthy non-diabetic women aged over 18 years were enrolled. After measurements of the anthropometric and metabolic parameters, correlation and multiple linear regression analyses were performed with regard to the CRP level, as a dependent variable, and with regards to age, blood pressure (BP), body mass index (BMI), lipid profiles, fasting plasma glucose levels, HOMA-IR and fat content as independent variables. RESULTS: In the multiple linear regression analysis, the CRP concentration was found to be independently associated with the E2 level, total fat content, leukocyte counts, and total cholesterol level in all subjects and the serum E2 levels was correlated with age, HOMA-IR, total cholesterol and the CRP level. When subjects were grouped according to their number of MS or IRS components, the CRP levels were found to show statistically significant differences between the MS and IRS groups. CONCLUSION: As a marker of chronic inflammation, the serum CRP level was independently associated with the components of MS and IRS. Also, the serum CRP and E2 levels were positively correlated. These results suggest that estrogen and CRP might play some independent roles in chronic inflammation which is a part of MS and IRS.

Abstract

- 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.
