- BACKGROUND
Many of the maturity-onset type 2 diabetic patients with hypertension and dyslipidemia in Korea are not associated with obesity. However, these patients are at risk for developing macrovascular complications such as atherosclerosis due to hyperinsulinemia, insulin resistance and abdominal obesity. The aims of this study were to compare the clinical and biochemical differences between the type 2 diabetic patients that are with and without abdominal obesity, and we also wished to investigate the degree of insulin resistance and atherosclerosis in these patients. METHODS: Among 530 type 2 diabetes mellitus (DM) patients, the percentages of under-weight (UW), normal-weight (NW), over-weight (OW) and obese (OB) (BMI <20, 20-25, 25-29.9 and > or =30, respectively) subjects were 8.9%, 62.1%, 25.1% and 3.9%, respectively. To evaluate the severity of their atherosclerosis, the coronary artery calcification (CAC) score was measured by electron beam computed tomography, and the intima-media thickness (IMT) of the common carotid artery and the ankle-brachial pressure index (ABPI) were also measured. The Insulin sensitivity index (ISI) was measured by the plasma glucose disappearance rate (kitt: %/min). RESULTS: 1. There were no differences in age, duration of DM and the HbA1c levels according to BMI for both the men and women, but the waist-hip ratio (WHR) and systolic blood pressure (SBP) were significantly different among each group. Serum triglyceride (TG), HDL-cholesterol (HDL-C), free fatty acid (FFA), fibrinogen, and fasting c-peptide levels, {excluding total cholesterol (TC)}, were also significantly different. The ISI, which is a marker for insulin resistance, as well correlated with the patients' BMI. Subjects having an with ISI above 2.5%/min were considered as having insulin resistance, and 28%, 60%, 68% and 75% of patients in the UW, NW, OW and OB groups, respectively, demonstrated insulin resistance. The visceral fat area/subcutaneous fat area ratio and visceral fat area/thigh muscle area ratio also increased with BMI. 2. The median values of the WHR were 0.95 for the men and 0.91 for the women. There were no significant differences for age, BMI, duration of DM and HbA1c between patients with and without abdominal obesity, but the SBP, TG, HDL-C, FFA, fibrinogen and ISI were significantly different between those two groups. 3. For the OW group as well as the NW group, the carotid IMT, ABPI and CAC scores were significantly different between the patients with and without abdominal obesity. However, there were no differences between the NW group and the OW group. CONCLUSION: In conclusion, those patients with abdominal obesity, regardless of their BMIs, have a higher prevalence for atherosclerosis, dyslipidemia, and hypertension, compared to those patients without abdominal obesity. Therefore, it is important to screen for atherosclerosis and to manage it accordingly, for the patients with insulin resistance or abdominal obesity in order to decrease their risk of developing atherosclerotic events.

- BACKGROUND
Insulin resistance in visceral obesity constitutes a risk factor for the development of atherosclerosis. The insulin resistance in obese type 2 diabetic patients can be improved by a decrease in the visceral fat and an increase in the skeletal muscle, which may influence the insulin sensitivity. Growth hormone (GH) accelerates lipolysis and promotes protein conservation. The effects of GH therapy, with diet restriction, on lipolysis and protein anabolism, were evaluated, which may change body composition, insulin resistance and atherosclerotic risk factors in obese type 2 diabetes mellitus. METHODS: Sixteen obese type 2 diabetic patients (31~56yrs), who had high glucose levels (glucose 12.8+/-1.7 mmol/L, HbA1c 10.2+/-2.1%), were treated with recombinant human GH (GH; 1 unit/d, 5 times/week), diet restriction (25 kcal/kg ideal body weight/day) and exercise (250 kcal/day) for 12 weeks. They underwent anthropometric measurement, bioelectrical impedance for total body fat and lean body mass, as well as computed tomography, for visceral and subcutaneous fat, at the umbilicus and muscle area at the mid-thigh levels. All subjects underwent the test for GH response to hypoglycemia. The insulin sensitivity index (ISI) was measured using insulin tolerance tests (ITT). RESULTS: 1. The visceral fat area (VFA)/thigh muscle area (TMA) ratio was more decreased in the GH-treated group than in the control group, but there was no change of body weight. 2. The ISI was significantly increased in only the GH-treated group, which was negatively correlated with the VFA/TMA ratio. The serum free fatty acid, fibrinogen and plasminogen activator inhibitor-1 were significantly decreased after the GH treatment. The serum glucose level and HbA1c remained unchanged during the GH therapy, but were significantly decreased after 3 months. 3. The total cholesterol and triglyceride levels were decreased in the GH treated group. 4. The insulin-like growth factor-I, fasting c-peptide and insulin level were all significantly increased after the GH treatment. CONCLUSION: This study suggested that in type 2 diabetic patients, with insulin resistance and uncontrolled blood sugar, GH treatment caused a decrease in the visceral fat and an increase in the muscle mass, which could result in the improvement of the ISI, atherosclerotic risk factors and dyslipidemia.

- BACKGROUND
Insulin resistance (IR) has been identified as a risk factor of atherosclerosis, which may be induced through a mechanism brought about by hypertension, obesity, glucose intolerance and dyslipidemia. The purpose of this study was to investigate the relationship between coronary artery disease (CAD) and insulin resistance. METHODS: Of 92 subjects having undergone coronary angiography 70 with significantly stenotic coronary artery were designated as the CAD group, with the other 22, without stenosis, as the control group. The CAD group was subdivided into 3 smaller groups according to the severity of their CAD; these being 1-vessel disease (group 1, n=31), 2-vessel disease (group 2, n=25), and 3-vessel disease (group 3, n=14). RESULTS: Kitt for patients with CAD was significantly lower than in the control group, and also for those in group 1 compared to groups 2 and 3, 2.72+/-1.29, 2.25+/-0.68 and 2.21+/-0.78%/min, with that of the controls being 3.01+/-1.22%/min p<0.05). There were significant differences between the IR group and the non-IR group in the common carotid artery intima-media thickness (1.09mm vs. 0.87mm, p<0.05), the waist-hip ratio (1.09 vs. 0.93, p<0.05) and the body fat contents (32% vs. 27%, p<0.05).Insulin resistance was assessed by the short insulin tolerance test, and the insulin resistance (IR) group was defined as having a Kitt less than 2.5%/min. CONCLUSION: These results suggest that insulin resistance is an important risk factor for CAD, and is related to the severity of coronary atherosclerosis.

- BACKGROUND
Type 2 diabetes with hypertension and dyslipidemia are frequently associated with metabolic obesity. It is proposed that such individuals might be characterized by increased insulin resistance and visceral fat, and that macrovascular complications might be more common in these individuals. Thereofer, the aim of this study was to investigate the atherosclerotic severity and risk factors in type 2 diabetic patients with metabolic obesity (MO) in Korea. METHODS: Coronary artery calcification (CAC) score, intima-media thickness (IMT) of common carotid artery, and ankle-brachial pressure index (ABPI) were measured. Insulin sensitivity index (ISI) was also measured by the plasma glucose disappearance rate (kitt: %/min). RESULTS: 1. Among 530 type 2 diabetes mellitus (DM) patients, the percent of under-weight (UW), normal-weight (NW), over-weight (OW) and obese (OB) (BMI< 20, 20-25, 25-29.9 and >30, respectively) were 8.9%, 62.1%, 25.1% and 3.9%, respectively. Waist-hip ratio and systolic blood pressure (sBP) were significantly different among the groups according to BMI. Serum triglyceride (TG), HDL-C, free fatty acid (fFA), fibrinogen and fasting c-peptide were significantly different among the groups. The percents of patients with insulin resistance in UW, NW, OW and OB groups were 28%, 60%, 68% and 75%, respectively. The visceral fat area/subcutaneous fat area ratio and visceral fat area/thigh muscle area ratio were significantly increased according to ISI. 2. The patients with MO have above the median values of WHR (0.95 in men and 0.91 in women). sBP, TG, HDL-C, fFA,fibrinogen and ISI were significantly different between the patients with MO and the patients without MO. 3. In OW group as well as NW group, carotid IMT, ABPI and CAC score were significantly different between the patients with MO and the patients without MO. However, these were not different between NW group and OW group. CONCLUSION: In conclusion, this study suggest that patients with MO have more advanced atherosclerosis and aggravated risk profiles for atherosclerosis than those without MO, regardless of BMI.

Abstract
- BACKGROUND
Homeostasis model assessment of insulin resistance (HOMAIR) had been proposed as a simple and inexpensive alternative to other complex procedures measuring insulin resistance. We evaluated the validity of HOMAIR, comparing to total glucose disposal rate measured by euglycemic clamp test in 63 subjects with normal glucose tolerance, 21 with impaired glucose tolerance and 47 with type 2 DM. METHODS: HOMAIR and HOMA cell function (Homeostasis model assessment of cell function) were calculated with formula described by Matthews [HOMAIR: fasting insulin ( U/mL) X fasting glucose (mmol/L) / 22.5, HOMA cell function: 20 X fasting insulin ( U/mL) / (fasting glucose (mmol/L) - 3.5)]. 2-hour euglycemic (5 mmol/L) hyper insulinemic (717 pmol/L) clamp test were carried out. RESULTS: The strong inverse correlation (r=-0.658, <0.001) was shown between log transformed HOMAIR and total glucose disposal rates. The agreement of two methodes in the categorization according to insulin resistance was moderate (weighed kappa=0.45). The magnitude of correlation coefficients were smaller in subjects with lower BMI (BMI < 23.7 kg/m2, r = -0.441 vs BMI > or = 23.7 kg/m2, r = -0.693, p = 0.0183), lower HOMA cell function (HOMA cell function < 57.2, r = -0.514 vs HOMA cell function > or = 57.2, r = -0.773, p = 0.0091) and higher fasting glucose levels (fasting glucose < 102 mg/dL, r = -0.697 vs fasting glucose > or = 102 mg/dL, r = -0.59, p = 0.0735). The results of correlation analysis was not significant in diabetics with lower BMI. CONCLUSION: Limitation of validity of HOMAIR should be carefully considered in subjects with lower BMI and lower fasting insulin to glucose levels, such as lean type 2 diabetes with insulin secretory defects.

- BACKGROUND
Our study was undertaken to investigate the pathogenesis and possible risk factors for post-renal transplantation diabetes mellitus (PTDM). METHODS: we recruited 114 patients with normal glucose tolerance, and performed the 75 g oral glucose tolerance tests (OGTT) and the short insulin tolerance tests 1 week before and 9~12 months after transplantation, respectively. RESULTS: The subjects were classified into three groups on the basis of OGTT after transplantation by WHO criteria: 1) 36 (31.6%) subjects with normal glucose tolerance; 2) 51 (45.7%) subjects with impaired glucose tolerance; and 3) 27 (23.7%) subjects with post-renal transplantation diabetes mellitus. Dosages of steroid and cyclosporin-A (CsA) were equivalent among the 3 groups. Before transplantation, the fasting and 2-h plasma glucose, and proinsulin/insulin (PI/I) ratios were significantly higher in the IGT and PTDM groups than in the NGT group, but insulin sensitivity index (ISI) was not different among 3 groups. In addition, the area under the curve (AUC)-insulin on OGTT was significantly lower in the PTDM group than in the NGT group. After transplantation, however, ISI was increased in all groups. Furthermore, the ISI and PI/I ratios revealed significantly higher values in the PTDM group than in the NGT group after transplantation. CONCLUSION: These results revealed that fasting and 2-h plasma glucose levels, as well as proinsulin/insulin ratio before transplantation, which may all be indicators of beta-cell dysfunction, could be the predictors for the development of PTDM and beta-cell dysfunction rather than insulin resistance was proved to be the main factor for the pathogenesis of PTDM.

- Bartter's syndrome is characterized by hypokalemia, metabolic alkalosis, hyperreninemia and secondary hyperaldosteronism without hypertension and edema, Histologically, existing hyperplasia of the juxtaglomerular cell occurs mostly in childhood or adolescence, and initial presentation in patients over 40 years old of age is very rare. It has been recorded that Bartter's syndrome is associated with glucose intolerance, but not with overt diabetes mellitus. Whether this association is coincidental or causal is uncertain, although hypokalemia can cause glucose intolerance. We experienced a case of Bartters syndrome in 44 years old non-insulin dependent diabetic woman. She improved with potassium supplements along with combination of prostaglandin synthetase inhibitor and aldosterona antagonist. We report present case with the review of literature.

- BACKGROUND
This study was undertaken to observe the changes of basal C-peptide level and to compare the clinical and immunogenetic characteristics in newly dignosed young age-onset diabetics in Korea. We studied predictors effecting the change of insulin secretory capacity in these patients. METHODS: 82 newly diagnosed young diabetic patients (mean age; 23.0+7.1, M:F=46:36) were divided into 3 groups according to the initial fasting serum C-peptide level (Classification I, group 1; C-peptide < 0.6 ng/mL, group 2; 0.6 ng/mL C-peptide <1.2 ng/mL, and group 3; 1.2 ng/mL C-peptide) and reclassified by the follow-up (mean follow-up; 3.7 year) fasting serum C-peptide level. RESULTS: According to the initial fasting serum C-peptide level, 17.1% (14/82) of the patients were classified as group 1, 35.4% (29/82) as group 2, and 47.5%(39/82) as group 3. In group 3, body mass index (BMI, p<0.01) and maximal BMI (p<0.01) at onset, family history of diabetes (p=0.01) and stimulated C-peptide increment were significantly higher than those in group 1 and 2. Presence of urine ketone (p<0.01), history of diabetic keto- acidosis (p<0.01), and frequency of insulin therapy at diagnosis (p<0.01) were significantly lower than those in group 1 and 2. No significant differences in onset age, sex, weight loss at onset, HbA1c, anti GAD antibody and HLA-DR were found among the 3 groups. After certain follow-up periods, 37.8% (31/82) of the patients were reclassified as group 1, 24.4% (20/82) as group 2, and 37.8% (31/82) as group 3 according to the follow-up fasting serum C-peptide level(classification II). All of the patients in group 1 in classification I were reclassified as group 1 in classification II. In group 2, 44.8% were reclassified as group 1 and 17.3% were reclassified in group 3. In group 3, 15.4% (6/39) of patients showed a significant decrease in insulin secretory capacity and were reclassified as type I diabetes, and their predictors for decreased insulin secretory capacity were low BMI at onset, low slimulated C-peptide increment, and antiGAD antibody. CONCLUSION: Our study showed that classification of newly diagnosed young diabetics by fasting C-peptide level is not always easy. Therefore follow-up measurement of C-peptide and consideration of clinical characteristics are needed in discriminating the type of diabetes in these groups of diabetics in Korea.

- BACKGROUND
Atherosclerosis is more prevalent in diabetic patients, severe and wide spread than in non-diabetic subjects and clinically evident as macrovascular diseases such as coronary, cerebro- vascular and peripheral arterial diseases which are important causes of frequent morbidity and premature mortality. But atherosclerotic vascular lesions are not easily detectable, before they advanced and cause symptoms. Measurement of carotid Intima-Media thickness(IMT) by high- resolution B-mode ultrasonography is a useful, non-invasive method to detect early atherosclerotic vascular changes. In this study, we investigated associations of IMT with cardiovascular risk factors. METHODS: High-resolution B-mode ultrasonography was performed in 63 non-insulin-dependent diabetic patients in order to determine maximal and mean carotid IMT. Blood pressure, glucose, HbA total cholesterol, HDL cholesterol and triglyceride levels were measured on a regular basis in the last 12 months before the carotid ultrasonography. The mean and last values at the time of the carotid ultrasonography were analyzed in relationship to the IMT. RESULTS: Carotid IMT was increased in NIDDM patients with male sex, smoking habit and hypertension. Systolic blood pressure (r=0.252, p=0.050) and LDL cholesterol levels (r=0.273, p=0.031) at the time of carotid ultrasonography showed a correlation with the IMT. Mean triglyceride (r=0.368, p=0.018) and HbA1c>, levels (r=0.288, p=0.045) of the last 12 months were correlated with the IMT. CONCLUSION: Increased carotid IMT was associated with male sex, smoking, hypertension, systolic blood pressure, LDL cholesterol, mean HbA, and triglyceride levels.

- BACKGROUND
Peripheral arterial disease (PAD) is one of the clinical manifestations of the atherosclerotic disease process. Early onset and rapid progression of PAD in diabetic patients has been well documented. PAD in diabetic patients has also been associated with an increased risk for total and cardiovascular mortality. Plethysmography is a noninvasive test to screen for the presence of PAD. Thus the aim of this study is to assess the risk factors for PAD screened by plethysmography in NII)DM patients. METHODS: A total of 289 NIDDM patients who undlerwent plethysmography were entered into our annlysis. Clinical characteristics of 38 patients with an ankle-brachial index of <0.9 (group B) were conapared with those of 231 patients with an ankle-brachial index of >1.0 (group A). RESULTS: Abnormalities in plethysmographic findings were found in 45.7% of diabetic patients. Age, duration of diabetes, hypertension, smoking, previous history of vascular diseases, HDL cholesterol, TC/HDL, and LDL/HDL appeared to be factors significantly related to PAD. Fasting sugar, HbAlc, total cholesterol, LDL cholestero1, trigly ceride, fibrinogen, lipoprotein(a), and waist-hip ratio were not significantly different between the two groups. The multiple logistic regression analysis showed the signficant contribution of the previous history of vascular disease (p=0.0028) and age (p-0.0115) to PAD in diabetic patients. CONCLUSION: The prevalence of PAD defined by plethysmography in our subjects was 45.7% higher than expected, suggests that efforts for early detection and prevention of PAD should be emphasized in diabetic patients.

- BACKGROUND
The euglycemic hyperinsulinemic clamp technique is currently regarded as gold standard for measuring insulin sensitivity, but it requires sophisticated equipment and highly trained personnel. We investigated the reliability of short insulin tolerance test as a simple tesl to measure in vivo insulin sensitivity. METHODS: Short insulin tolerance test(SITT) and euglyeemic hyperinsulinemic clamp test were performed at random order in 14 healthy subjects and 10 abnormal glucose tolerant subjects. The plasma glucose disappearance rate(kitt: %/min) after iv injection of regular insulin(0.1U/kg) was determinecl and compared to insulin sensitivitv indices(M, M/I) of euglycemic hyperinsulinemic clamp test. RESULTS: The mean Kitt value of healthy subjects was 3.50+0.75%/min and that of subjects with abnormal glucose tolerance was 2.56+0.56%/min. Changing sampling time from 15 min to 18~21 min and sampling interval from 3 min to 1.5 min had no influence on Kitt value. Kitt values were reproducible in six subjects, with a CV of 8.8+2.0%. There was a highly significant correlations between the Kitt value derived from SITT and M or M/I derived from euglycemic hyperinsulinemic clamp test. There were no significant adverse effects including hypoglycemic symptom while performing SITT. CONCLUSION: SITT is simple, safe, rapid to perform, and provides reliable index of in vivo insulin sensitivity. It seems particularly suitable for studies involving large series of subjects or including repeated evaluation of insulin sensitivity.

- Diabetic muscle infarction(DMI) is an uncommonly reported complicatian of diabetes mellitus, DMI tends to occur in younger, poorly controlled diabetic patients with other end organ complications(retinopathy, nephropathy, neuropathy). The typical feature of DMI is abrupt onset of thigh pain, tenderness, and swelling, over a period of days, and a firm mass develops. There are no associated systemic symptoms or signs indicative of infection and no skin discoloration suggestive of cellulitis or thrombophlebitis. The patient was diagnosed as DMI with the findings of ultrasonographic, bone scan and magnetic resonance imaging as well as typical clinical and laboratory findings. The painful mass persists for weeks, occasionally with exacerbation of symptoms, and then spontaneously resolves over several montks. Immobilization of the extremity with prolonged bed rest and strict sugar control has had beneficial results. We report a case of diabetic muscle infarction in a 30-year-old woman with insulin dependent diabetes mellitus
