Abstract PDF: BACKGROUND
Polycystic ovary syndrome (PCOS) is a common endocrine disease affecting 5~10% of women with reproductive age. Familial aggregation suggests the evidence supporting a genetic basis for PCOS. The mode of inheritance of PCOS is not yet clear, however, probably polygenic and might be related to insulin resistance. Polymorphism of peroxisome proliferator-activated receptor (PPAR)-gamma gene is a susceptible gene for the development of obesity and diabetes. In this study, we examined the frequency and genetic effect of PPAR-gamma polymorphism on insulin resistance or hyperandrogenemia in Korean women with PCOS. METHODS: One-hundred twenty five Korean women with PCOS were evaluated for their metabolic and reproductive hormonal status. PPAR-gamma polymorphism was analyzed. RESULTS: Genetic frequency of PPAR-gamma was not significantly different between women with PCOS (n = 125) and those with regular menstrual cycles (n = 344). PCOS with Pro12Ala polymorphism had significantly higher levels of waist circumference and subcutaneous fat area compared with those with Pro12Pro genotype. They also had tendency of higher levels of fasting glucose concentration, body mass index (BMI) and visceral fat area. After BMI adjustment, this polymorphism was related to lower fasting insulin and higher insulin sensitivity index, and higher sex hormone binding globulin and lower free testosterone levels. CONCLUSION: Pro12Ala polymorphism of PPAR-gamma gene might be associated with obesity. However, after BMI adjustment, it may have favorable effect on insulin resistance and hyperandrogenemia. Because this study has limitations to conclude the genetic causality, further study is needed to support these findings.

BACKGROUND
The prevalence of diabetes is steadily increasing in Korea. The increase in number of people with diabetes would ultimately result in premature death, poor quality of life, and increasing economic burden. However, in our country, researches regarding on the quality of diabetes management are lacking. This study was conducted in 2005 using National Health Insurance Database to know the current status of diabetes management in Korea. METHODS: We have randomly selected 3,902 subjects out of 2,503,754 subjects who had claims with diagnosis of diabetes between January 2003 to December 2003 by using two staged cluster sampling method. Field survey with review of medical records and telephone survey was conducted with standardized record forms developed by Korean Diabetes Association; Task Force Team For Basic Statistical Study of Korean Diabetes Mellitus. RESULTS: The age of diabetic subjects was 58.1 +/- 12.6 years and the duration of diabetes was 6.2 +/- 5.5 years. Hypertension was present in 54% of diabetic subjects. Among those with hypertension, 59% were controlled with blood pressure below 140/90 mmHg, but only 19% were controlled with blood pressure below 130/80 mmHg. Hyperlipidemia was present in 29% of diabetic subjects. Only 38% of those with hyperlipidemia were controlled with LDL-cholesterol below 100 mg/dL. For glycemic control, only 40% of diabetic subjects achieved the goal of HbA1c less than 7%, which was suggested by ADA. CONCLUSION: We found that only 20~40% of diabetic subjects in Korea achieved the management goal for glucose, blood pressure, and lipids. It seems urgent to develop a quality management program for diabetes subjects in Korea.

Abstract PDF

BACKGROUND
The continuity of care in chronic diseases, especially in diabetes, was emphasized from many studies. But large scale studies with long-term observation which confirm the impact of continuity of care on health outcomes are rare. This study tried national level 3 year observation to find differences in hospitalization, mortality and medical costs among patient groups with different utilization pattern. METHODS: The 1,088,564 patients with diabetes diagnosis and diabetes drug prescription in 2002, from 20 to 79 years old, and survived until the end of 2004 were included. Annual drug prescription days, number of visited clinics and quarterly continuity of care were measured. Gender, age group, living area, health insurance premium level (as a proxy of the income level), years of first DM diagnosis, five co-morbidities (hypertension, heart disease, stroke, renal disease, admission with DM), hospitalization experience and the type of main attending clinic were adjusted. Hospitalization, mortality and high costs group (top quintile) in 2005 were predicted by multiple logistic regression model. RESULTS: Patients who failed in continuity of care in 2003 and 2004 showed higher hospitalization (OR =1.29), higher mortality (OR =1.75) and they are more likely to be high costs group (OR =1.34) in 2005 than who fulfilled the continuity of care. Patients who have single attending clinic also showed lower hospitalization, lower mortality and lower cost. Completeness in diabetic drug prescription were correlated with lower hospitalization, lower mortality but with higher cost. Possible cost saving from continual care with single attending clinic was estimated at Won 417 billion (Dollar 1 = Won 943.7). Possible expenditure from complete drug prescription was Won 228 billion. So, net saving was Won 139 billion in our study population. CONCLUSION: Continual care and single attending clinic saves patient's life and national costs. Fragmented primary care system in Korea should be reformed for more effective care of chronic diseases. National Health Insurance Database in Korea enables nationwide long-term observation study which overcomes the many limitations found in hospital-based studies and cross-sectional surveys.

Abstract PDF

BACKGROUND
Foot ulcer diseases are more prevalent in diabetic patients than that those of non-diabetic patients. Several reports showed the risk of amputation and the medical cost were increased when foot ulcer developed. Therefore, strict glycemic control from the initial period of diabetes is necessary. Since there is no enough epidemiologic data, large scaled studies for medical and economic consequences about diabetic foot ulcer are needed. METHODS: This study was based on health insurance claims submitted to the National Health Insurance Review Agency during the period from December 1994 through December 2002. We investigated the incidence and medical cost of foot disorders in Korean population using the disease-classification codes on the health insurance claim forms. RESULTS: The incidences of foot disorders (per 100,000 of population) were 49.7 for amputations, 99.7 for ulcers, and 1,051 for injuries in diabetic patients, and 4.2 for amputations, 10.3 for ulcers, and 943 for injuries in non-diabetic patients. Relative risk of the incidences of foot amputation, ulcer, and injury in diabetic patients comparing with non-diabetic patients were 11.7, 9.7, and 1.1, respectively. Total medical costs (per capita) of foot amputation, ulcer, and injury in diabetic patients were 2.0, 1.7, and 2.1 times higher, respectively, than those of non-diabetic patients. Mean hospital stay of foot amputation, ulcer, and injury in diabetic patients were 1.6, 1.3, and 1.7 times more, respectively, than those of non-diabetic patients. CONCLUSION: In diabetic patients, the incidences of foot amputation and ulcer are higher than those of non-diabetic patients. To reduce those incidences, we need to early strict glycemic control as well as government based management.

Abstract PDF

AIMS: ADA guidelines recommend aspirin for all patients with diabetes who have had a prior CHD events as well as a primary prevention strategy among those with at least one other risk factor. We examined the current status of regular aspirin intake among Korean adults who diagnosed as diabetes. METHODS: This study examined the characteristics of aspirin user in new-onset diabetes over 40 years based on health insurance claims submitted to the Health Insurance Review Agency (HIRA) of Korea during the period from January 2001 through December 2003. New onset diabetes defined as the first health insurance claim of antidiabetic drugs submitted to HIRA for the three months (January to March 2001) that never submitted for previous 6 years. RESULTS: The number of total new-onset diabetic patients was 30,014 in 2001, 29,819 in 2002, and 32,061 in 2003. The incidence rate of diabetes over 40 years for 3 months in 2001, 2002 and 2003 were 0.172%, 0.167% and 0.18. Mean age of women who diagnosed diabetes were significant higher than that of men in 2001 (women 59.2+/-10.6 yrs, men 54.8+/-9.8 yrs), in 2002 (women 59.5+/-10.6 yrs, men 54.6+/-9.3 yrs) and in 2003 (women 59.6+/-10.7 yrs, men 54.7+/-9.9 yrs) (p < 0.001). The number of aspirin user increased from 2,065 (6.9%) in 2001, 2,638 (8.9%) in 2002 and 3,711 (11.6%) in 2003. 30.5% of new-onset diabetics in 2001 had hypertension, 12.4% of them had hypercholesterolemia, 11.8% of them had cerebral infarct, 2.6% of them had cerebral hemorrhage, 3.8% of them had coronary heart disease and, but, 55.6% of them had not any CVD. Logistic regression analysis using aspirin use as a dependent variable showed that the number of aspirin use in patients with hypertension, hypercholesterolemia, cerebral infarct and coronary heart disease was higher than in patients without those (hypertension [OR], 3.89 (95% CI, 3.52~4.31); hypercholesterolemia [OR], 2.16 (95% CI, 1.90~2.46; cerebral infarct [OR], 2.05 (95% CI, 1.82~2.30); coronary heart disease [OR], 9.41 (95% CI, 8.20~10.80), respectively). Coronary heart disease was the most important associated factor of aspirin use. CONCLUSIONS: We found significant underuse of aspirin therapy among our population compared with that of America. Major efforts are needed to increase aspirin use in diabetic patients.

Abstract PDF

BACKGROUND
Diabetes is becoming one of the main causes of end-stage renal disease (ESRD) worldwide. We studied the prevalence and incidence of end-stage renal disease (ESRD) in the Korean population based on health insurance claims submitted to the Health Insurance Review Agency. We also investigated the proportion of medications taken by the ESRD patients, and frequency of hospital admission or visits, and medical expenses between ESRD patients with and without diabetes. METHODS: This study was based on health insurance claims submitted to the Health Insurance Review Agency during the period from January 2001 through December 2003. Using the disease-classification codes on the health insurance claim forms, those who were diagnosed with chronic renal disease (N18 or N19) and received dialysis-related treatment (Z49), treatment with a kidney dialysis machine (Z99.2), or kidney transplantation (Z94.0) were defined as ESRD patients. Among the ESRD patients, those who were diagnosed with diabetes (E10-E14) and/or took anti-diabetic drugs were defined as ESRD patients with diabetes. RESULTS: The ESRD patients totaled 33,870 in 2001, 37,894 in 2002, and 41,167 (858.3 per million population) in 2003. ESRD patients with diabetes increased to 56.7% in 2003. The number of ESRD patients in whom renal replacement therapy was initiated was 8,134 in 2002 and 8,322 (173.5 per million population) in 2003. ESRD patients with diabetes used more anti-hypertensive drugs (1.2 times as many), lipid-lowering drugs (1.6 times), and anti-platelet agents (1.8 times) than did ESRD patients without diabetes. In 2003, 66.5% of the ESRD patients with diabetes were hospitalized, which was 1.6 times the hospital admissions of ESRD patients without diabetes. ESRD patients with diabetes also had hospital stays that were 1.6 times longer per patient and inpatient service expenses that were 1.6times greater per patient, compared with those reported for ESRD patients without diabetes. CONCLUSION: The incidence of ESRD accompanied by diabetes has risen rapidly. Given the burden of medical treatment costs placed on ESRD patients with diabetes, more aggressive interventions should be implemented to prevent diabetes and renal complications among patients with diabetes.

Abstract PDF

BACKGROUND
Polycystic ovary syndrome (PCOS) is characterized by insulin resistance and consequent hyperinsulinemia. Insulin resistance plays an important role in the development of metabolic syndrome (MS). We conducted a cross-sectional study to determine the prevalence of the MS and whether the insulin resistance or hyperandrogenemia is related to the MS in young Korean women with PCOS. METHODS: 143 women with PCOS (mean age 26+/-5 years) were studied to evaluate the prevalence of MS by modified Adult Treatment Panel III. Insulin sensitivity was evaluated by euglycemic hyperinsulinemic clamp technique. RESULTS: The prevalence of MS in women with PCOS was 11.9%, 2.8-fold higher than age matched women in Korean urban population. The most frequent component of MS was low HDL cholesterol (39.4%), and the least frequent one was high fasting serum glucose levels (6.7%). The frequency of MS was 40.7% in obese PCOS (BMI > or = 25 kg/m2, n = 38), 10.0% in overweight PCOS (BMI 23~24.9 kg/m2, n = 13), and 0% in lean PCOS (BMI < 23 kg/m2, n = 92). The frequency of MS was 26.1% in insulin resistant PCOS (insulin mediated glucose uptake, IMGU < lowest 10th percentile of lean controls, n = 65), whereas no one had MS in insulin sensitive PCOS (IMGU > or = lowest 10th percentile of lean controls, n = 78). CONCLUSION: MS is frequent in young women with PCOS, and obesity and insulin resistance might be essential for the development of MS in this study group.

Abstract PDF

BACKGROUND
Insulin resistance is prevalent in women with polycystic ovary syndrome (PCOS), and it makes them to have high risk for development of type 2 diabetes. Evaluation of insulin sensitivity would be important to predict their risks. Although the euglycemic-hyperinsulinemic clamp technique is the gold standard for measuring insulin sensitivity, it is too hard to practice in large epidemiologic studies. The aim of this study is to verify the validity of various insulin sensitivity indexes from oral glucose tolerance test (OGTT) in women with PCOS. METHODS: We performed euglycemic-hyperinsulinemic clamp (target glucose; 90 mg/dL, insulin ;~1 mU/kg.min) to obtain insulin-mediated glucose disposal rate (M-value) in 62 non-diabetic women with PCOS (BMI < 23 kg/m2; n = 37, BMI > or = 23 kg/m2; n = 25). Homeostasis model assessment [HOMA(IR)], quantitative insulin sensitivity check index (QUICKI), glucose to insulin ratio (G/I ratio), whole body insulin sensitivity index [ISI(COMP)], metabolic clearance rate of glucose [MCR(est)-OGTT(1,2)], and insulin sensitivity indexes [ISI(est)-OGTT(1,2)] were calculated from plasma glucose and insulin levels from standard 75-g OGTT. The correlations of various insulin sensitivity indexes from OGTT with M-value were evaluated. RESULTS: In lean women with PCOS (BMI < 23 kg/m2, n = 37), ISI(COMP) (r = 0.36, P < 0.05), MCRest-OGTT1 (r = 0.49, P < 0.01), ISI(est)-OGTT(1) (r = 0.50, P < 0.01), MCR(est)-OGTT(2) (r = 0.45, P < 0.01) and ISI(est)-OGTT(2) (r = 0.40, P < 0.05) were significantly correlated with M-value. In overweight and obese women with PCOS (BMI > or = 23 kg/m2, n = 25), HOMA(IR) (r = -0.40, P < 0.05), QUICKI (r = 0.40, P < 0.05), MCR(est)-OGTT(1) (r = 0.76, P < 0.001), ISI(est)-OGTT(1) (r = 0.63, P < 0.001), MCR(est)-OGTT(2) (r = 0.58, P < 0.01) and ISI(est)-OGTT(2) (r = 0.42, P < 0.05) showed significant correlations with M-value. CONCLUSION: MCR(est)-OGTT(1) and ISI(est)-OGTT(1) were the most reliable and easily accessible insulin sensitivity indexes obtained from OGTT for measuring of insulin sensitivity in women with PCOS regardless of obesity.

Abstract PDF: BACKGROUND
Insulin resistance is considered a regular component of polycystic ovary syndrome (PCOS). However, several studies have failed to confirm insulin resistance in non-obese women with PCOS. The aim of the study was to identify whether insulin resistance is present in normal weight women with PCOS and the factors associated with insulin sensitivity. METHODS: Twenty-two normal weight (body mass index, BMI < 25 kg/m2) women with PCOS, and 16 age and BMI comparable control women with regular menstrual cycles were examined during their early follicular phase. The levels of serum hormones and lipids were measured. The visceral fat area was assessed by computed tomography at umbilical level. The standard 75g oral glucose tolerance test was performed to determine the glucose tolerance status. The insulin sensitivity was measured using the euglycemic hyperinsulinemic clamp technique (target glucose 90 mg/dL, insulin~1 mu/kg/min). RESULTS: The levels of free testosterone (1.9+/-0.6 pg/mL vs. 0.8+/-0.3 pg/mL, p<0.001), androstenedione (14.5+/-3.7 nmol/L vs. 8.8+/-1.3 nmol/L, p<0.001), LH (10.7+/-4.5 IU/L vs 4.6+/-4.8 IU/L, p<0.001) and FSH (5.8+/-1.7 IU/L vs. 4.2+/-2.4 IU/L, p<0.05) of the women with PCOS were significantly higher than those of the control subjects. The fasting plasma glucose (4.92+/-0.31 mmol/L vs. 4.42+/-0.61 mmol/L, p<0.01) and post glucose load plasma insulin (233.2+/-119.5pmol/L vs. 109.0+/-46.4 pmol/L, p<001) levels of women with PCOS were significantly higher than those of the control subjects. The glucose disposal rate (M value) was significantly lower in women with PCOS compared to the controls (5.3+/-1.2 mg/kg min vs. 6.7+/-1.6 mg/kg min, p<0.05), even after adjusting for age and BMI. There was no significant correlation of the M value with the anthropometric and a metabolic indices, and a multiple regression analysis of the M value showed no significant variables. CONCLUSION: Our non-obese women with PCOS showed significant insulin resistance compared to their age and BMI comparable control subjects, and-their insulin resistance may be an intrinsic defect not associated with other features, such as hyperandrogenemia or body fat distribution patterns.

Abstract PDF: BACKGROUND
Insulin resistance is an intrinsic defect of polycystic ovary syndrome (PCOS), and elevated levels of cytosolic free calcium in insulin target cells may cause insulin resistance. To our knowledge, the relationship between intracellular calcium and insulin resistance in PCOS has not been investigated. The purpose of this study was to determine whether the levels of intracelluar calcium are changed and if they have any association with insulin resistance in women with PCOS. METHODS: The intracellular calcium levels in the platelets and the insulin sensitivity were measured by fluorescent spectrophotometry and the euglycemic hyperinsulinemic clamp technique, respectively, in 16 women with PCOS and 6 normal cycling women. A 2h, 75 g oral glucose tolerance test was performed to determine the glucose tolerance. RESULTS: The insulin sensitivity measured by the glucose disposal rate(the M-value), was significantly lower in women with PCOS(4.6+/-1.5mg/kg/min vs. 7.0+/-1.3mg/kg/min, p<0.01), but the intracellular calcium levels were significantly higher in women with PCOS compared to the controls(122.7+/-36.7 vs 59.1+/-29.3mmol/L, p<0.01). When the women with PCOS were divided into the overweight or obese(n=9, BMI ?23kg/m2) and lean(n=7, BMI<23kg/m2) groups, both groups had significantly lower M values compared to the control subjects(3.9+/-1.3, 5.5+/-1.2 vs. 7.0+/-1.3mumg/kg/min, p<0.001), and these levels between the overweight/obese and lean PCOS groups showed a significant difference(p<0.001). The overweight/ obese and lean women with PCOS had significantly higher levels of intracellular calcium compared to the control subjects(131.3+/-39.6, 111.7+/-31.8 vs. 59.1+/-29.3nmol/L, p<0.01), but these levels did not differ significantly between the overweight/obese and lean women with PCOS. The intracellular calcium levels showed a significant positive correlation with age, and a negative correlation with the M value(r=-0.55, p<0.05). The BMI-adjusted partial correlation showed marginal significance between elevated levels of intracellular calcium and insulin sensitivity (r=-0.47, p=0.07). CONCLUSION: Women with PCOS showed both insulin resistance and increased levels of intracellular calcium compared to the control subjects. Increased levels of intracellular calcium were associated with insulin resistance in women with PCOS.

Abstract PDF: BACKGROUND
To determine whether hyperleptinemia is a principal component of metabolic syndrome in a Korean population using factor analysis. METHODS: Metabolic syndrome was defined by the NCEP-ATP III guideline. An oral glucose tolerance test was performed, and plasma samples for leptin and lipid profiles were collected from 199 men and 426 women who had no history of diabetes, hypertension, dyslipidemia, or of taking lipid-lowering, antihypertensive, or antihyperglycemic medications. RESULTS: Leptin level was correlated with overall and central obesity, blood pressure, and glucose or insulin levels in men and women aged 30 to 83. Before and after adjustment for BMI, leptin level was significantly and positively correlated, in women only, with insulin and with insulin resistance, as assessed by a homeostasis model assessment (HOMA) (Ps<0.0001). Factor analysis identified the following four factors from among the metabolic syndrome variables; an obesity/hyperinsulinemia factor, a glucose intolerance factor, a hypertension factor, and a dyslipidemia factor in men. Leptin was clustered as an obesity/ hyperinsulinemia and a dyslipidemia factor in men. In women, four different groups were found: an obesity/hypertension factor, a glucose intolerance factor, an obesity/dyslipidemia factor, and an obesity/hyperinsulinemia factor. Leptin was clustered as an obesity/hyperinsulinemia factor in women. CONCLUSION: Our research suggests that leptin level is associated with metabolic syndrome in relation to obesity and hyperinsulinemia. Moreover, obesity, as opposed to hyperinsulinemia, is related to hypertension or dyslipidemia in women only, and this gender differences may reflect different roles of central adiposity on metabolic abnormalities.

Abstract PDF: BACKGROUND
Diabetes has recently become a major public health problem due to the socioeconomic changes in Korea. Epidemiological data for diabetes are needed to establish disease control and health improvement programs in the community. Considering the tendency for larger concentrations of the population in the urban areas of Korea, epidemiological studies in these areas are essential. This this was performed to determine the epidemiologic characteristics, prevalence, and incidence of diabetes in Korean urban communities. METHODS: The target cohort of this study was randomly selected from 20,222 residents living in the Mokdong apartment areas one, two, five and six, Yangcheon-Gu, Seoul. Of the 20,222 residents, 1,011 were residents, of which 766 (male 264, female 502) subjects participated and 372 subjects without diabetes at baseline examination followed up for 2 years. At the baseline and follow-up examination, all subjects underwent a 75g oral glucose tolerance test (OGTT) and anthropometric measurements (height, weight, waist to hip ratio, pulse rate, blood pressure, and subcutaneous skin fold thickness) were performed. RESULTS: There was an 8.5% prevalence of diabetes and 7.8% with impaired glucose regulation (IGR), including impaired glucose tolerance (IGT) and impaired fasting glucose (IFG). The age-adjusted prevalence of diabetes IGR were 8.4% and 7.1%, respectively. The prevalence of diabetes or IGR increased with increasing age. The prevalence of diabetes was associated with aging, family history of diabetes, and high levels of waist to hip ratio. The age-adjusted annual incidence rate of diabetes for subjects over 40 years of age at the baseline was 1.3%. The risk factors for the development of incident diabetes, from a multiple logistic regression analysis, were the waist to hip ratio and the 2-hour postload serum glucose concentrations. CONCLUSION: The prevalence of diabetes in the Mokdong apartment area was slightly higher than in Yonchon, Jungup, or Beijing. The annual incidence of diabetes was lower than that found in the studies in Yonchon or in Pima Indian, but higher than those of Caucasians or American Hispanics.

Sex Hormone Binding Globulin, Body Fat Distribution and Insulin Resistance in Premenopausal Women.: Young Sook Lee, Hye Jin Lee, Jee Young Oh, Young Sun Hong, Yeon Ah Sung; Korean Diabetes J. 2003;27(1):63-72. Published online February 1, 2003

Abstract PDF: BACKGROUND
Low levels of sex-hormone binding globulin (SHBG), an indirect index of androgenicity, have been reported to be associated with obesity, especially central obesity. In women, increased androgenicity is related to hyperinsulinemia, impaired glucose tolerance and the development of type 2 diabetes mellitus. Recent studies have suggested that the relationship between SHBG and insulin resistance was mediated by the change in total or visceral adiposity, and that ethnical differences in the relationship between sex hormone and body fat distribution might exist. METHODS: We examined the associations of SHBG to the body fat distribution and insulin resistance in Korean premenopausal women. The fasting serum level of SHBG was measured by RIA, and the insulin sensitivity by the minimal model derived sensitivity index (SI), using the insulin modified intravenous glucose tolerance test. The amount of body fat, and its distribution, were assessed by anthropometric measurement, bioelectric impedance analyses, and computed tomography at the level of the umbilicus. RESULTS: 1. SHBG was significantly inversely correlated with the body mass index (BMI), waist circumference, visceral fat area, and fasting insulin levels, and was significantly positively correlated to the SI. 2. SHBG was significantly lower in premenopausal women with an impaired glucose tolerance, compared to those with a normal glucose tolerance, and significantly lower in those with hypertension (systolic BP> or =140 mmHg or diastolic BP> or =90 mmHg), compared to those with normal blood pressure. SHBG was also significantly lower in persons with central obesity(waist circumference > or = 80 cm) compared to those without. 3. In a multiple linear regression analysis, the SI was significantly associated with SHBG, after adjustment for age, BMI, systolic blood pressure, triglycerides, HDL- cholesterol, and percentage body fat, but this association disappeared after additional adjustment for visceral fat area. 4. In a multiple linear regression analysis, the fasting plasma insulin, BMI and percentage body fat were significant independent factors associated with SHBG. CONCLUSION: Increased androgenicity as assessed by decreased serum SHBG concentrations, is strongly associated with an unfavorable body fat distribution, hypertension, glucose intolerance, hyperinsulinemia, and insulin resistance.

Abstract PDF: BACKGROUND
Although it is well known that insulin secretory defects and insulin resistance are major pathogenetic factors of type 2 diabetes, their relative importance still remains controversial in various ethnic groups. Increased levels of proinsulin, and the proinsulin/insulin (PI/I) ratio, are considered markers of pancreatic dysfunction, and predictors for the development of type 2 diabetes. To reveal which pathogenetic abnormality is most prominent in Koreans with type 2 diabetes, we measured the insulin sensitivity and secretory capacity in the normal glucose tolerant offspring of patients with type 2 diabetes. METHODS: Sixty-two offspring, with normal glucose tolerance (mean age 40.4+/-6.5 BMI 23.4+/-2.7 kg/m2), of type 2 diabetes parents, were compared with and 20, age and BMI-matched control subjects, with on family history of diabetes. We measured the serum levels of proinsulin (PI), specific insulin (I), and C-peptide(C) and calculated the PI/I and C/I ratios, as parameters of hepatic insulin clearance. The insulin sensitivity index (SI) was measured by the intravenous glucose tolerance test (IVGTT) using the MINMOD program, as a marker of insulin sensitivity. The acute insulin response to glucose (AIRg), AIRg by product, SI and the area under the insulin curve (AUCinsulin) were measured by IVGTT, and used as a marker of the insulin secretory capacity. We also evaluated the association between the proinsulin and insulin secretory capacities. RESULTS: Offspring of the type 2 diabetic patients had significantly lower AIRg SI and AUCinsulin (p<0.05), and tended to have lower AIRg (p=0.06), than the control subjects. However, there was no significant difference in the SI between the two groups. However, with the proinsulin, and the insulin, PI/I and C/I ratios, not significant differences were found between the offspring and the control subjects, and the PI/I ratio was not correlated with AIRg, AIRg x SI or SI. CONCLUSION: Insulin secretory defect could be a more prominent factor in the development of type 2 diabetes in Koreans, with no change in the proinsulin secretion.

Abstract PDF: BACKGROUND
Angiotensin converting enzyme (ACE) gene polymorphism has been known to related to atherosclerotic heart disease such as acute myocardial infarction or left ventricular hypertrophy, diabetic nephropathy or retinopathy, as well as, insulin sensitivity. However, an exact relationship between ACE gene polymorphism and aforementioned diseases have not been fully established. It has been suggested that NIDDM and atherosclerosis may have common pathogenesis since some of NIDDM patients already have atherosclerotic changes at the time of the initial diagnosis. Futhermore, offspring of NIDDM patients are considered as a high risk group for both NIDDM and atherosclerosis, and these two disorders are known to be affected by some common genetic factors. Therefore, in the present study, we planned to investigate, by analyzing female offspring of NIDDM patients (offspring), the relationship of ACE gene polymorphism to insulin resistance and atherosclerosis. METHODS: Fifty-three female offspring of patients with NIDDM were participated in this study, and twenty age-BMI matched normal glucose tolerant subjects without a family history of diabetes were selected as the controls. Based on 75-g oral glucose tolerance test, subjects were divided into normal glucose tolerance (n=42) or impaired glucose tolerance (n=ll). We assessed the patterns of body fat distribution by anthropometric measurement, bioelectric impedence analysis and computed tomogram; insulin sensitivity by minimal model analysis using insulin modified frequently sampled intravenous glucose tolerance test; carotid intima-medial thickness by ultrasonography. We investigated the alleles of the ACE gene by PCR. RESULT: 1. ACE genotypes in offspring were distributed as follows; 39.6% for II, 32.0% for ID, 28.4% for DD 55.7% for I al#lele, 44.3% for D allele. This distribution was not significantly different from those in controls (35.0% for II, 55.0% for ID, 10.0% for DD, 62.5% for I allele, and 37.5% for D allele). 2. There was no significant difference in body mass index (BMI), systolic and diastolic blood pressure, and serum lipid concentrations among three genotypes. However, in the subjects with ID genotype, VSR was significantly increased compared to the subjects with DD genotype (p<0.05). In the subjects with ID genotype, percent body fat, visceral fat area, CIMT were increased, and SI and SG were decreased in comparison to II and DD subjects, although the differences between the two groups did not reached the statistical significance. 3. When the subjects were divided into quartiles of CIMT, the frequency of ID genotype of ACE showed the tendency of increment from the lowest to the highest quartile of CIMT. 4. Multiple regression analysis showed that ACE genotypes was significantly associated with visceral obesity, carotid intima-medial thickening and insulin sensitivity. CONCLUSION: ACE genotypes was not significantly associated with visceral obesity, carotid intima- medial thickening and insulin sensitivity. However, to explore the true associations of ACE gene polymorphism with insulin resistance and ather-osclerosis, we further suggest and recommend prospective studies.

Abstract PDF: Diabetic hyporeninemic hypoaldosteronism is clinically defined syndrome which is characterized by hyperkalemic hyperchloremic metabolic acidosis in patients with diabetic autonomic neuropathy and nephropathy. The major cause of hyporeninemia in diabetes mellitus is the impairement of activation from glycated prorenin to renin. Hyperkalemia is major disorder of this syndrome which is almostly chroniclly developed but acutely developed in case of diabetic patients because of hyperglycemia and hyperkalemic symptoms are usually absent or mild. We experienced a case of diabetic hyporeninemic hypoaldosteronis complicated with acute severe hyperkalemia, myalgia and muscle weakness. The patient complained severe pain and muscle weakness of posterior neck and both lower extremities, serum potassium concentration was 8.5 mEq/L, serum muscle enzymes were very high and electrocardio gram showed ventricular premature beat and generalized T wave inversion. Plasma renin activity and aldosterone concen trations were below normal limits and not stimulated by furosemide administration. After the conservative management of hyperkalemia and g]ycemic control with insulin, serum potassium leve1 and muscle enzymes were normalized.

Abstract PDF: BACKGROUND
Erectile dysfunction is the consistent inability to achieve or sustain an erection of suffieient rigidity for sexual intercourse. Erectile dysfunction is an important cause of decreased quality of life in diabetic men. The prevalence of ereciile dysfunction has been reported to be three times higher in diabetic men than nondiabetics. Erectile dysfunction in diabetic men has been associated with increased age, poor glycemic control, smoling, alcohol intake, depression, and microvascular diabetic complication. Our purpose was to determine the prevalence of erectile dysfunction in diabetic men and to assess risk factors re]ated to erectile dysfunction in diabetes mellitus. METHODS: From l53 diabetic men visiting Ewha Womans University Hospital from March, 1997 to March, 1998, we analyzed the self-reported questionnaires. Three questions about erection and one question about overall sexual satisfaetion were given and the answer to each question was categorized into 5 degrees according to the severity of sexua] dysfunction. Erectile dysfunction was diagnosed when any answer for erection showed a degree lower than 4. We obtained the history of smoking, alcohol and hypertension, and measured the current weight and height. Fasting glucose, HBA 1c and lipid profile were me measured. We also evaluated for the presence of diabetic retinopathy, nephropathy and neuropathy. RESULTS: 1) The self-reported prevalence of erectile dysfunction in diabetic men was 75.5 % in this study. 2) In the patients with erectile dysfunction, age, duration of diabetes mellitus, HbAlc, and systolic blood pressure were significantly higher, and BMI and triglyceride significantly lower than in the patients without erectile dysfunction. 3) The prevalence of erectile dysfunction was increased with aging and increasing duration of diabetes mellitus, HBA. was significantly positively related and BMI was inversely related to erectile dysfunction. 4) Age and HbA 1c were independently and positively related to erectile dysfunction by multiple logistic regression. 5) The erectile dysfunction was significantly associated with diabetic autonomic neuropathy and retinopathy. CONCLUSION: The prevalence of self-reported erectile dysfunction in diabetic men was 75.5 % in this study, and it was significantly related to aging and the degree of the glycemic control.

Abstract PDF: BACKGROUND
Sex hormone-binding globulin (SHBG) has been known to be associated with obesity, central fat accumulation and insulin resistance and thought to be a indirect marker for androgenicity in women. The relationships between circulating dehydroepiandrosterone(DHEA). dehydroepiandrosterone sulfate(DHEA-S) levels and body fat accumulation are still controversial. We conducted a cross-sectional study to eva]uate the relationships between serum levels of SHBG, DHEA-S, body fat distribution pattern and insulin sensitivity in women. METHODS: We tested 57 women(age 30~65yr; BMI 18.5~32.8kg/m, 45 premenopausal on the 5~10 day of the menstrual cycle, 12 postmenopausal who were not using hormone replacement therapy) with varying degree of glucose tolerance(32 normal glucose tolerance(NGT), 17 impaired glucose tolerance(IGT) and 8 newly diagnosed diabetes). lnsulin sensitivity was measured as minimal model derived sensitivity index(S) using insulin modified IV glucose tolerance test and fasting serum levels of SHBG and DHEA-S were measured by RIA. Body fat distribution pattern was assessed by waist to hip ratio(WHR),% body fat measured by bioelectrical impedance analyzer, subcutaneous fat area(SFA), visceral fat area(VFA) and VFA to SFA ratio(VSR) at the level of umbilicus using the computed tomography. RESULTS: 1) Measured SHBG and DHEA-S levels were not significantly different among subjects with NGT, IGT and diabetes. 2) SHBG was inversely associated with age, BMI, WHR, diastolic blood pressure, VFA, SFA, VSR,% body fat, fasting insulin and positively associated with S, whereas DHEA-S did not show any significant correlation with above variables except diastolic blood pressure. 3) SHBG level was significantly lower(p<0.05) and DHEA-S level was insignificantly lower (p=0.05) in postmenopausal women than in premenopausal women but the significance disappeared after adjustment for age, BMI, WHR and% body fat. 4) BMI was independently and negatively related to S, WHR and fasting insulin to SHBG by multiple regression analysis. CONCLUSION: We confirmed that SHBG was independently associated with central obesity and fasting hyperinsulinemia. However, S was independently associated with BMI only. It suggested that hyperinsulinemia in insulin resistance might cause the decreased level of SHBG even thaugh the directionality of the association was uncertain because of a cross-sectional nature of this study.
