BACKGROUND
The aim of the study was to classify newly diagnosed diabetic patients who initially presented with diabetic ketoacidosis (DKA) into specific types of diabetes and to describe the clinical and biochemical characteristics of patients with fulminant type 1 DM in Korea. METHODS: Using data from 4 hospitals of CMC from 1 January 1999 to 1 March 2008, we identified all patients who manifested DKA when they were first diagnosed as diabetes. Clinical and laboratory data were reviewed from medical records. RESULTS: We identified 51 newly diagnosed diabetic patients manifested DKA. Among them, 14 (27.4%) patients were classified as autoimmune type 1 DM, 8 (15.7%) as antibody negative type 1 DM, 5 (9.8%) as fulminant type 1, 16 (31.4%) as type 2 DM and 8 (15.7%) as secondary DM. Five patients who fulfilled the criteria of fulminant type 1 DM were older (32.2 +/- 10.7 vs. 15.7 +/- 4.4 years, P = 0.010), had shorter duration of symptoms (4.2 +/- 2.7 vs.16.7 +/- 15.2 days, P = 0.014) and lower stimulated C-peptide levels (0.1 +/- 0.0 vs. 0.7 +/- 0.6 ng/mL, P = 0.050) compared with patients with autoimmune type 1 DM. CONCLUSION Newly diagnosed diabetic patients presenting with DKA composed of heterogenous types of diabetes. The prevalence of fulminant type 1 diabetes among them was 9.8% and the clinical and biochemical characteristics of these patients were different from those of autoimmune type 1 DM.

Abstract PDF: Chronic inflammatory demyelinating polyneuropathy (CIDP) is an immune-mediated disorder characterized by the symmetrical weakness in both proximal and distal muscles for at least 2 months, hyporeflexia or areflexia, nerve conduction abnormalities, and high CSF protein level. Diabetes mellitus, monoclonal gammopathy, hepatitis C infection, HIV infection, SLE, Sjogren syndrome and lymphoma have been associated with CIDP. The incidence of CIDP in diabetes is not known exactly, but occur more common among diabetic than nondiabetic patients. There is sometimes a difficulty in distinguishing between diabetic polyneuropathy and CIDP, but differential diagnosis is important because CIDP is treatable with immune-modulating therapy. We report a case of CIDP in 22-year-old girl with type 1 DM who presented with generalized motor weakness and walking disturbance which were treated with iv immunoglobulin

Abstract PDF: BACKGROUND
It has been reported that a decrease in the beta-cell mass, may play a major role in the development of type 2 diabetes. Some stimuli that cause beta-cell loss can stimulate neogenesis from precursors as well as replication of matured beta-cells. In an animal-based studies reported that alpha-cells can also be produced in the course of alpha-cell neogenesis, after being treated with streptozotocin. Through this research, we attempted to determine the change of beta-cell mass according to the changes in alpha-cell mass and to characterize the size of the beta-cell nucleus observed in type 2 diabetes. METHOD: To estimate the relative fraction of alpha- and beta-cell mass in the pancreas, we counted beta-cells and alpha-cells by point count method. We also performed a double immunohistochemical staining with glucagon and insulin antibodies to calculate the ratio between these two cells area in the pancreas (A/B ratio). In order to measure the size of the beta-cell nucleus, an immunofluorescence staining of the nucleus and insulin was carried out. Data were gathered from type 2 diabetic subjects (n=19) and normal controls (n=8). RESULTS: Although there was no statistical difference, we observed the tendency of decrease of beta-cell mass and increase of alpha-cell mass in the pancreas of type 2 diabetic patients. The ratio of alpha-to beta-cell area in islet (A/B ratio) increased to 0.81+/-0.76 in diabetic patients compared to control with 0.26+/-0.25 (p<0.01). The mean of the A/B ratios of the islets more than 22,000 micro m2 was 1.64+/-1.10, whereas that of the islets less than 22,000 micro m2 was 0.73+/-0.67 in type 2 diabetic patients (p<0.01). The size of the beta-cell nucleus in both diabetic subjects and normal controls was bigger than that of exocrine cells (p<0.05) and 2.9% of beta-cells in type 2 diabetic subjects showed substantially enlarged nuclei more than M+5SD (M and SD means the average and standard deviation of nucleus size of exocrine cells, respectively) whereas this type of nucleus was found in only 0.5% of beta-cells in normal controls (p<0.05). CONCLUSION: The islet pathology in type 2 diabetes could be characterized by an expansion of alpha-cells associated with the selective loss of beta-cells. Some beta-cells found in diabetes showed a significant increase in size of the nucleus. Through the results from this study, we postulate that enlarged beta-cell nucleus and reverse of A/B ratio in the islets could be a marker of early senescence of beta-cells in patients with type 2 diabetes mellitus.

Abstract PDF: BACKGROUND
Insulin resistance is one of the major pathophysiology of type 2 diabetes mellitus. It is reported that cilostazol and cyclic AMP phosphodiesterase inhibitor has the anti-platelet effect as well as an improvement of hypertriglyceridemia in addition to vasodilatation. Furthermore, the previous reports indicated that there is a positive relationship between insulin resistance and dyslipidemia. Thus, we investigated the effects of cilostazol on insulin resistance in OLETF rats using the euglycemic hyperinsulinemic glucose clamp technique, and lipid levels. METHODS: Fifteen five months old OLETF rats were fed for 4 weeks(8 treated with cilostazol and 7 were control), and compare to 20 same aged LETO rats (8 treated with cilostazol and 12 were control) through the glucose infusion rate on euglycemic hyperinsulinemic glucose clamp and lipid profiles. RESULTS: The glucose infusion rate was higher in the cilostazol treated OLETF rats than in the non-cilostazol treated OLETF rats (0.021+/-0.0031 vs 0.027+/-0.0036 mL/min). The levels of free fatty acids (2424.8+/-652.7 vs 1061.8+/-223.2 Eq/L), total cholesterol (145.7+/-17.9 vs 115.4+/-7.6 mg/dL) and triglyceride (146.5+/-46.6 vs 76.1+/-12.5 mg/dL) of cilostazol treated OLETF rats were significantly lower than those of non-cilostazol treated OLETF rats. CONCLUSION: This study result suggest that cilostazol may improve the insulin resistance through the improvement of dyslipidemia in OLETF rats.

Abstract PDF: BACKGROUND
We performed this study to investigate the effect of metformin on glycemia, insulin secretion and body weight in patients with non-insulin-dependent diabetes melltus(NIDDM) who could not aehieve satisfactory glycemic control by sulfonylurea or diet therapy. METHODS: A total of 167 patients with NIDDM were included in this study. At baseline the patients underwent anthropometry and a 75g oral glucose tolerance test. Jn addition, levels of hemoglobin Alc (HbAlc), setum lipids, fasting and postprandial 2hr glucose were measured. Metformin was given in an initial dose of 500mg twice daily and increased by 500mg every month as long as the fasting blood sugar(FBS) concentration exceeded 7.8mmol/L and the side effects were tolerable. After 3 rnonths of metformin therapy we defined a responder as a patient who experienced a FBS of under 7.8 mmol/L or a HbAlc of under 7%. Patients who failed to respond to metformin monotherapy were excluded in the study. Anthrapometric changes and results of a 75 g oral glucose tolerance test were reevaluated in the responder group after 6 months of metformin treatment. RESULTS: I) The overall response rate to metformin mono-therapy was 55.6%(79/142) in the study population. 2) There were significant changes in body weight (64.4+/-8.2 vs 62.9+/-8.4 kg, p(0.01) and body mass index(25.3+/-2.3 vs 24.6+/-2.3kg/m, p<0.01) during metformin treatment. 3) There were significant decreases in the fasting, postprandial 2hr serum glucose(10.1+/-2.8 vs 7.9+1.6, 15,2+/-5.0 vs 12.2+/-3.9 mmol/L, p 0.01) and HbAlc levels(8.4+/-1.7 vs 6.5+/-0.9%, p<0.05) after 6 months of metformin treatment. 4) There were significant decreases in the levels of AUC[g](59.2+/-15.5 vs 49.4+/-9.4mmol L-1. Min-1, p =C0.01) without changes of AUC[I] and AUC[I]/ AUC[g] ratio (558.0+486.0 vs 536.4+374.4 pmol.L-1. Min-1, p=0.71, 11.7+/-13.0 vs 11.8+/-10.0, p=0.89). 5) The incidence of side effects was 25% in the study population, but most of them were mild and fade away with continuous use of metformin, CONCLUSION: Metforrnin monotherapy improved glycemic control in NlDDM patients who failed to respond to diet or sulfonylurea therapy and may be a useful hypoglycemic agent for the treatment of NIBDM.
