Abstract

- Generally, most cases of diabetes mellitus (DM) are classified as either type 1 DM or type 2 DM based on their pathophysiolgic features. However, it is not always possible to classify this disease clearly according to current diagnostic criteria. Recently, the existence of non-typical diabetes has been found in patients with simultaneous features of both type 1 and type 2 DM. In these patients, obvious evidence of insulin resistance, positivity of islet autoantibody, and progressive beta cell loss are observed concurrently. Moreover, this non-typical diabetes that usually occurs among children and adolescents has been defined as 'double diabetes', and its worldwide incidence has been on the increase as of late. Thus, there has been heightened interest among researchers about this ambiguous condition.

- BACKGROUND
The angiotensin converting enzyme inhibitor (ACEi) improves the vascular endothelial cell function and has a better clinical outcome by decreasing the LDL cholesterol oxidation, hypercoagulability, oxidative stress and improving the level of endothelial nitric oxide synthesis in patients with type 2 diabetes and hypertension. However, the correlations between the ACEi and the serum markers for the vascular endothelial function in previous studies were not consistent. SUBJECTS AND METHODS: Between July 2003 and April 2005, 104 type 2 diabetes patients with hypertension, who had been admitted to 9 major university hospitals in Korea, were examined. The subjects were randomly allocated to the cilazapril (2.5~5 mg/day) and atenolol (50~100 mg/day) treatment group and given a combination of hydrochlorothiazide and amlodipine. The lipid profile and the markers for endothelial function, such as vWF, VCAM, E-selectin, tPA, fibrinogen, adiponectin, hsCRP, nitrotyrosine were evaluated and the differences in the variables were compared with those obtained 6 months later. RESULTS: A total 56 subjects completed the 6-months follow up period. Regarding the baseline characteristics, there were no significant differences in the variables observed in the two groups except for HbA1c (P = 0.037), vWF (P = 0.048), and hsCRP (P = 0.038). After 6 months, both groups showed a significant and identical decrease in the systolic and diastolic blood pressure compared with the baseline (P < 0.002). However, there were no significant differences in the endothelial markers between each group. On the other hand, there was some deterioration in the triglyceride (P = 0.009) and HbA1c (P = 0.017) levels in the atenolol treatment groups. CONCLUSIONS: There were no significant differences in the endothelial function markers observed between the cilazapril and atenolol groups. However, cilazapril had an identical effect on the blood pressure reduction compared with atenolol but had fewer adverse effects on the glucose and lipid metabolism.

- BACKGROUND
To evaluate the relationships between deterioration in insulin secretion and aggravated insulin resistance in patients with newly diagnosed prediabetes (preDM) and type 2 diabetes mellitus (T2DM) according to the presence of metabolic syndrome (MS). METHODS: We performed oral glucose tolerance test (OGTT) on 322 drug naive subjects with a history of hyperglycemia of < or = 3 months, and divided these patients into 3 groups, normal glucose tolerance (NGT), preDM (IFG and/or IGT) and T2DM. We also diagnosed these subjects with respect to MS according to ATP III criteria modified by Asia-Pacific guidelines and compared IGI and HOMA-IR in the 3 groups. RESULTS: According to OGTT, 63 subjects were diagnosed with NGT, 81 with preDM, and 178 with T2DM. Using modified ATP III criteria, 218 (67.7%) subjects were diagnosed as MS. When compare groups stratified by the presence of MS, preDM and T2DM groups with MS showed significantly higher mean HOMA-IR and IGI than those without MS. When compare groups with respect to glucose tolerance, NGT, preDM, and T2DM subgroups in MS group showed significant higher HOMA-IR and lower IGI according to glucose tolerance. However, NGT, preDM, and T2DM subgroups in non-MS group showed a significant decrease in IGI but no significant difference in HOMA-IR as glucose tolerance worsened. CONCLUSION: Deterioration in IGI and aggravation of HOMA-IR are both important in the primary pathogenesis of diabetes in those with MS. However, IGI deterioration may be the only important factor in the primary pathogenesis of T2DM in the absence of MS.

- BACKGROUND
Finger pricking is currently the common method of blood glucose measurement in patients with diabetes mellitus. However, diabetes patients have proven reluctant to regularly check their glucose profiles because of the small amount of blood that is required. Recently, a non-invasive and continuous glucose monitoring device that is based on reverse iontophoresis(GlucallTM) has been developed. In this study we wanted to evaluate the accuracy and the clinical acceptability of this new device. METHODS: The study was conducted during the period from November 2003 to January 2004 on 19 in-patients who had been admitted to Kyung Hee University Hospital. Glucose measurements using GlucallTM were performed between 10am and 4pm. The concurrent plasma glucose levels were checked hourly and they were subsequently compared with the GlucallTM data. RESULTS: The mean error(ME) of the GlucallTM measurements was -3.45+/-52.99mg/dL with a mean absolute relative error(MARE) of 20+/-15.16%. Measurements obtained by GlucallTM had a correlation coefficient of 0.784(P<0.05) with the plasma glucose levels, as was determined by linear regression analysis. This correlation was consistent regardless of the time of data collection. However, after excluding such confounding variables as age and gender, the correlation coefficient exhibited a tendency to increase. 98.9% of the results were clinically acceptable according to Clarke error grid analysis. CONCLUSION: GlucallTM does not yet have the reliability and accuracy to wholly replace the conventional methods. However, further technical advancements to reduce its shortcomings will make this device useful for the management of diabetes patients

Abstract

- The insulin pump is an effective glycemic control device those function is analogous to the physiologic regulation of insulin in vivo. When sufficient patient education and proper selection of patients is done, the insulin pump is one of the most effective treatment modalities for diabetic patients. However, various side effects and complications might occur during its application. We report here on an unusual case of diabetic ketoacidosis that was caused by acute inflammatory colitis and insulin pump malfunction. Peculiarly, the cause of pump malfunction was far removed from its mechanical problem. We concluded that the cause of the insulin pump malfunction was due to abdominal subcutaneous fat atrophy and the lipohypertrophied nodules of the patient that developed due to the prolonged usage of the insulin pump.
