BACKGROUND
Mechanism for glucose toxicity is known to be an increased oxidative stress produced by multiple pathways. In our previous report, 2-deoxy-d-ribose (dRib) promoted apoptosis by increasing oxidative stress in a pancreatic beta-cell line. We performed this study to investigate the mechanism of dRib-induced damage of beta-cells. METHODS: HIT-T15 cells were cultured in RPMI-1640 medium with 40 mM dRib for 24 hours after pretreatment with various concentrations of a metal chelator (DTPA) and inhibitors of protein glycation (aminoguanidine and pyridoxamine). Cell viability was determined by MTT assay. Apoptosis was analyzed by flow cytometry with annexin V/PI double staining. RESULTS: DTPA, which inhibits the monosaccharide autoxidation, partially reversed dRib-induced cytotoxicity in a dose-dependent manner (P < 0.01). The cytotoxicity was also suppressed dose-dependently by aminoguanidine (AG) and pyridoxamine (PM) (P < 0.05 and P < 0.01, repectively). Flow cytometric analysis showed that pretreatment of DTPA and AG also reversed the dRib-triggered apoptosis in a dose-dependent manner. We assessed the additional protective effects of inhibitors of protein glycation from dRib-induced cytotoxiciy in the presence of a metal chelator. The additions of AG (P < 0.05) and PM (P < 0.01) significantly reduced the cytotoxicity compared with DTPA alone group. CONCLUSION: This results suggest that dRib produce cytotoxicity and apoptosis through the mechanisms of advanced glycation endproducts (AGEs) formation including the monsaccharide autoxidation and protein glycation in pancreatic beta-cell. Thus, dRib could be a surrogate for glucose in the study of glucose toxicity and chronic diabetic complications.

Abstract PDF: BACKGROUND
Islet transplantation is one of regimens supplying the deficient insulin in diabetes patients, but the effects of islet grafts on the changes of endogenous beta-cells are not clear. In the present study, we examined the changes of endogenous beta-cell mass after islet transplantation in partially pancreatectomized mice. METHODS: Balb/c mice were 70% pancreatectomized, transplanted with syngeneic islets (group IV), and were compared with pancreatectomized mice treated with insulin (group III) or no insulin (group II). Blood glucose levels and body weight were monitored. Remnant pancreas was obtained at 6 or 10 days after pancreatectomy, and immunohistochemical staining was done for the evaluation of beta-cell mass changes. RESULTS: Hyperglycemia and weight loss were induced after pancreatectomy. After islet transplantation or insulin treatment, blood glucose levels recovered to normal, and body weight started to increase. Plasma insulin levels were higher and beta-cell mass was larger in group IV than in group II (P < 0.05). Especially, the difference of beta-cell mass between them was more evident at 7 days as compared to at 3 day after transplantation. When compared to group III, group IV showed larger individual beta-cell area after 7 days and larger beta-cell mass after 3 days of islet transplantation (P < 0.05). CONCLUSION: These observations indicate that islet transplantation plays a role in enhancing remnant beta-cell regeneration after partial pancreatectomy in rodents.

Abstract PDF

BACKGROUND
Korean type 2 diabetic patients are known to differ from western diabetes because of their unique characteristics, such as non-obese but centrally obese anthropometry and relatively more insulin secretory defects than insulin resistance compared to western diabetic patients. METHODS: We recruited 1,646 diabetic patients in the present study and excluded the 45 patients with fasting C-peptide < 0.20 nmol/L. We had assessed insulin secretion by fasting serum C-peptide level and insulin resistance by short insulin tolerance test (Kitt ; rate constant for plasma glucose disappearance, %/min) in the private diabetes clinic. The insulin secretory defect was divided by severe (C-peptide < 0.37 nmol/L), moderate (C-peptide 0.37~0.56 nmol/L), and normal (C-peptide > or = 0.57 nmol/L) group. The insulin resistance was divided by insulin resistant (IR) (Kitt < 2.5 %/min) and insulin sensitive (IS) (Kitt > or = 2.5 %/min) group. RESULTS: We analysed the data of 1,601 type 2 diabetic patients (831 men and 770 women, age 56.5 +/- 10.8 years, duration of diabetes 9.6 +/- 7.3 years). The prevalence of BMI > or = 25.0 kg/m2 is 42.5% and BMI > or = 23.0 kg/m2 is 70.2%. The prevalence of abdominal obesity (waist > or = 90 cm in men and 80 cm in women) is 45.2% (36.0% and 55.2%, respectively in men and women). Fasting C-peptide level is 0.64 +/- 0.29 nmol/L and Kitt value is 2.03 +/- 0.96%/min. According to fasting C-peptide level, the degree of insulin secretory defect were severe (13.1%), moderate (33.0%) and normal (53.9%). According to Kitt value, the IR group is 70.6% and the IS group is 29.4%. CONCLUSION: Obese type 2 diabetes is markedly increasing in Korea. Therefore, the major problem in Korean type 2 diabetic patients is being changed into insulin resistance instead of insulin secretory defect.

Abstract PDF: BACKGROUND
In many studies, obesity is highly correlated with adverse coronary risk profile. Increased left ventricular (LV) mass is an independent risk factor for cardiovascular mortality and morbidity. Hypertension is an well known factor related with LV mass. Obesity also is related with LV mass and commonly associated with hypertension. However, few data are available concerning the relations of LV mass to central obesity, especially in Korean hypertensive patients. So, this study was to evaluate the significance of waist circumference in determinants of LV mass in Korean hypertensive patients. METHODS: A total of 74 hypertensive [40 women, 34 men; mean age, 62.5 years; mean body mass index (BMI), 25.0 kg/m2, 17 with type 2 diabetes] patients without prevalent cardiovascular disease were studied. Echocardiographic LV septal thickness, LV posterior wall thickness, LV dimension and LV mass were analysed. RESULTS: LV mass, diastolic left ventricular internal dimension and epicardial fat thickness were larger in men than in female. LV mass was larger in obese patients defined by body mass index and also in central obese patients defined by waist circumference. LV mass was correlated with sex, body mass index, waist circumference, diastolic left ventricular internal dimension, left ventricular posterior wall thickness and interventricular septal thickness. After controlling for age, sex and body mass index, waist circumference was correlated with LV posterior wall thickness and LV mass. CONCLUSION: Waist circumference may be more important than BMI in determinants of left ventricular mass in Korean hypertensive patients.

Abstract PDF

BACKGROUND
Adipose tissue produces and releases a variety of proinflammatory cytokines. The aim of this study was to investigate whether proinflammatory cytokines are increased and insulin resistance is presented in nonobese women with high body fat and low fat free mass. METHODS: Sixty nonobese adult premenopausal women (body mass index, BMI < 25 kg/m2) were included in this study. Body composition was determined by dual energy absoprtiometry (DXA). Fasting glucose, lipid profiles, tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), C reactive protein (CRP) and basal insulin were measured. RESULTS: The subjects with high body fat (> or = 30%) had higher CRP levels (P = 0.024), IL-6 levels (P = 0.008), insulin levels (P = 0.003), and homeostasis model assessment-IR (HOMA-IR) (P = 0.020) than those of the subjects with low body fat. In a subset of 32 subjects with high body fat (> or = 30%), the number of subjects with high fat free mass index (FFMI) (> or = 13.5 kg/m2) had higher atherogenic index than that of subjects with low FFMI (FFMI < 13.5 kg/m2) (P < 0.05). IL-6 was correlated with % body fat, fat mass index (FMI), and fat mass (P < 0.05). HOMA-IR was correlated with % body fat and FMI (P < 0.05). To investigate predictors of cytokines and HOMA-IR, multiple regression analysis was used. % body fat was a predictor for IL-6 and, while age and % body fat were predictors of HOMA-IR in study subjects. Conclusions: This study suggests that insulin resistance may be present in nonobese women with high body fat and low fat free mass.

Abstract PDF: BACKGROUND
Transforming growth factor-beta is known to play a role in the interaction between metabolic and hemodynamic factors in mediating accumulation of extracellular matrix in the diabetic nephropathy. TGF-beta1 gene polymorphism was associated with circulating TGF-beta levels and influenced the pathogenesis of fibrotic diseases including diabetic nephropathy. In this study, we examined the relationship between TGF-beta1 gene codon 10 polymorphism and type 2 diabetic nephropathy with more than 10-year history of disease. METHODS: We conducted a case-control study, which enrolled 325 type 2 diabetes. A total of 176 patients with diabetic nephropathy were compared with 149 patients without diabetic nephropathy. TGF-beta1 codon 10 genotyping was determined using polymerase chain reaction with sequence specific primers method. RESULTS: Distribution of TGF-beta1 codon 10 genotype in the patients either with nephropathy or without nephropathy is confined to Hardy-Weinberg equilibrium. The patients with nephropathy have higher frequency of TGF-beta1 GA/GG genotypes than the patients without nephropathy [GA/GG:AA = 119 (67.6%) : 57 (32.4%) vs. 80 (53.7%) : 69 (46.3%), P < 0.05]. Among patients with diabetic nephropathy, those with TGF-beta1 GA/GG genotypes had higher serum levels of total cholesterol and LDL-cholesterol. CONCLUSION: Our results suggest that TGF-beta1 gene codon 10 polymorphism may contribute to the type 2 diabetic nephropathy.

Abstract PDF

BACKGROUND
Peripheral neuropathy is a common complication of diabetes mellitus, contributing the greatest morbidity and mortality and impairing the quality of life. Recently the receptor of erythropoietin (Epo) was proven to be expressed in neuronal cell and recombinant human Epo (rhEpo) has been shown to have neuroprotective and neurotrophic potential in peripheral neuropathy. But there is no report about baseline Epo level in blood before rhEpo treatment with diabetic peripheral neuropathy. METHODS: From Jan. 2000 to Sep. 2006, diabetic patients were reviewed about Epo level in blood, anemia, and peripheral neuropathy in Chonbuk National University Hospital. And we compared the mean value of baseline Epo level in diabetic patients with anemia according to the peripheral neuropathy. RESULTS: The mean value of Epo of patients with peripheral neuropathy was lower than that of patients without peripheral neuropathy (16.3 +/- 7.1 vs 26.1 +/- 29.7 mU/mL, P < 0.05). There was no significance in the correlation between hemoglobin and Epo level in diabetic patients with anemia irrespective of presence of peripheral neuropathy (r = -0.02, P = 0.81). CONCLUSION: We suggest that decreased Epo level in blood is possible to be an additional cause in the development of peripheral neuropathy. However, simultaneously another possibility that neuropathy causes reduced Epo level should be considered, so further studies are warranted in this field.

Abstract PDF

BACKGROUND
For decades, exercise has been considered a cornerstone of diabetes managements, along with diet and medication. Many studies have shown that regular physical activity improves quality of life, reduces the risk of mortality from all causes, and is particularly advantageous in subjects with impaired glucose tolerance or type 2 diabetes mellitus. However, high-quality evidence and basic data on the importance of exercise and physical fitness in Korean diabetic patients were lacking until recent years. METHOD: This study included 240 diabetic patients (122 men, 118 women) recruited from 6 diabetic centers in Korea. To measure step length and walking velocity at normal walking speed, we made the patient walk 12 meter at normal speed. The patients wore the pedometer for 7 days and we got the equation between the walking steps per day and calorie expenditure for 7 days. From the equation, we calculated appropriate steps, distance and duration of walking in type 2 diabetic patients as exercise program RESULTS: In men, the walking velocity was 4.4 +/- 0.6 km/h and step length was 67.6 +/- 7.3 cm at normal walking speed. In women, the walking velocity was 4.0 +/- 0.6 km/h and step length was 58.4 +/- 5.5 cm at normal walking speed. The equation between kcal per week and steps per day was that kcal/week = (steps/day) x 0.268 + 64.074 (R2 = 0.854, P < 0.01) in men and kcal/week in women = (steps/day) x 0.256 - 39.005 (R2 = 0.890, P < 0.01). The steps/day, walking distance and walking duration which correspond to 700 kcal/week was 2,373 steps/day, 21.9 minutes and 1,604 meter in men, and 2,887 steps/day, 25.3 minutes and 1,690 meter in women at normal walking speed. CONCLUSION: To exert at least 700 kcal/week with exercise, it is recommended that type 2 diabetic patients walk at least 25 minutes/day or 1,700 meter/day or 2,500 steps/day in men and 30 minutes/day or 1,800 meter/day or 3,000 steps/day in women at normal walking speed.

Abstract PDF

BACKGROUND
Mitiglinide, one of the meglitinides, is expected to prevent postprandial hyperglycemia of type 2 diabetes by enhancing early phase insulin secretion. The aim of this study was to verify the efficacy and safety of mitiglinide compared to nateglinide. METHODS: One hundred eleven of diabetic patients were randomised and administered of mitiglinide (n = 56) and nateglinide (n = 55) before a meal time for 12 weeks. The changes of HbA1c, fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) were analyzed. The safety of this drug was investigated as well. RESULTS: The change of HbA1c was not significantly different between two groups (-0.77 +/- 1.08% in mitiglinide vs. -0.66 +/- 0.79% in nateglinide, P = 0.57). The reduction of FPG (-12.2 +/- 25.0 mg/dL vs. -6.1 +/- 22.3 mg/dL, P = 0.218), PPG 1 hr (-48.0 +/- 47.1 mg/dL, vs. -29.4 +/- 43.2 mg/dL, P = 0.051), and PPG 2 hr (-59.2 +/- 58.0 mg/dL vs. -43.3 +/- 59.0 mg/dL, P = 0.194) were not significantly different between the mitiglinide and the nateglinide, respectively. Drug-related adverse effects were not different between two groups (16.1% in mitiglinide vs. 27.8% in nateglinide, P = 0.137). The frequency of hypoglycemic events were not different between two groups (8.9% in mitiglinide vs. 14.8% in nateglinide, P = 0.339). There were two patients who had complained shoulder pain in the mitiglinide or deterioration of visual acuity in the nateglinide, but those were found to be unrelated with medications. CONCLUSION: This study showed that mitiglinide had reduced HbA1c as similar to nateglinide and that significantly improved HbA1c, FPG and PPG during 12 weeks of treatment. The safety of mitiglinide was also comparable to nateglinide. Mitiglinide could be used as an effective glucose-lowering agent by enhancing early insulin secretion and reducing postprandial glucose excursion, and thereby might contribute long-term cardioprotective effect in Korean type 2 diabetic patients.

Abstract PDF

Recently type 1 diabetes with acute onset and no evidence of islet autoantibodies have been showed as "fulminant type 1 diabetes" and as novel subtype of type 1B diabetes. The study was made progress in Japan. We report a typical case of fulminant type 1 diabetes. A 24 years old male to be in good condition visited our hospital because of flu-like symptom, diarrhea, and abdominal discomfort. He has no medical history and family history of diabetes. The level of plasma glucose is 962 mg/dL, serum ketone body 5.8 mmol/L, arterial blood pH 7.111 and he was diagnosed as diabetic ketoacidosis. Anti-GAD antibody and islet cell antibody were negative and HbA1c is 5.5%. All of them were compatible with the diagnostic criteria of fulminant type 1 diabetes. After the patient has been treated with insulin, his symptoms were improved and abnormal laboratory data were normalized. We report this case with a review of the literature.

Abstract PDF

Type 1 diabetes is characterized by insulin deficiency due to destruction of pancreatic beta-cells. A novel subtype of type 1B which is rapidly developed without any evidence of autoimmunity has been recently proposed as fulminant type I diabetes. In female patients of child-bearing age, the onset of fulminant type 1 diabetes occurred frequently during pregnancy or after delivery in Japan, however, there was no report about fulminant type 1 diabetes associated with pregnancy in Korea. We report a case of fulminant type 1 diabetes associated with pregnancy. A 28-year-old woman suffering from excessive thirst with vomiting and general weakness after four days from normal spontaneous vaginal delivery presented to our hospital. Laboratory examination revealed a high blood glucose level and evidence of diabetic ketoacidosis, butHbA1c level was normal. These findings suggested a very recent onset of diabetes mellitus. Serum C-peptide level was very low level. Antibodies to glutamic acid decarboxylase (GAD) was weakly positive. After fluid and insulin based management, patient successfully recovered without any serious complication.
