 Abstract
 PDF Supplementary Material PubReader  ePub
- The Korean National Health Information Database (NHID) contains big data combining information obtained from the National Health Insurance Service and health examinations. Data are provided in the form of a cohort, and the NHID can be used to conduct longitudinal studies and research on rare diseases. Moreover, data on the cause and date of death are provided by Statistics Korea. Research and publications based on the NHID have increased explosively in the field of endocrine disorders. However, because the data were not collected for research purposes, studies using the NHID have limitations, particularly the need for the operational definition of diseases. In this review, we describe the characteristics of the Korean NHID, operational definitions of endocrine diseases used for research, and an overview of recent studies in endocrinology using the Korean NHID.

- Background
It is well known that high serum ferritin, a marker of iron storage, predicts incident type 2 diabetes. Limited information is available on the association between transferrin, another marker of iron metabolism, and type 2 diabetes. Thus, we investigated the association between transferrin and incident type 2 diabetes.
Methods
Total 31,717 participants (mean age, 40.4±7.2 years) in a health screening program in 2005 were assessed via cross-sectional analysis. We included 30,699 subjects who underwent medical check-up in 2005 and 2009 and did not have type 2 diabetes at baseline in this retrospective longitudinal analysis.
Results
The serum transferrin level was higher in the type 2 diabetes group than in the non-type 2 diabetes group (58.32±7.74 μmol/L vs. 56.17±7.96 μmol/L, P<0.001). Transferrin correlated with fasting serum glucose and glycosylated hemoglobin in the correlational analysis (r=0.062, P<0.001 and r=0.077, P<0.001, respectively) after full adjustment for covariates. Transferrin was more closely related to homeostasis model assessment of insulin resistance than to homeostasis model assessment of β cell function (r=0.042, P<0.001 and r=–0.019, P=0.004, respectively) after full adjustment. Transferrin predicted incident type 2 diabetes in non-type 2 diabetic subjects in a multivariate linear regression analysis; the odds ratio (95% confidence interval [CI]) of the 3rd tertile compared to that in the 1st tertile of transferrin for incident diabetes was 1.319 (95% CI, 1.082 to 1.607) after full adjustment (P=0.006).
Conclusion
Transferrin is positively associated with incident type 2 diabetes in Koreans.

- Background
Diabetes can be efficiently prevented by life style modification and medical therapy. So, identification for high risk subjects for incident type 2 diabetes is important. The aim of this study is to identify the best β-cell function index to identify high risk subjects in non-diabetic Koreans. MethodsThis is a retrospective longitudinal study. Total 140 non-diabetic subjects who underwent standard 2-hour 75 g oral glucose tolerance test from January 2007 to February 2007 at Kangbuk Samsung Hospital and followed up for more than 1 year were analyzed (mean follow-up, 54.9±16.4 months). The subjects were consist of subjects with normal glucose tolerance (n=44) and subjects with prediabetes (n=97) who were 20 years of age or older. Samples for insulin and C-peptide levels were obtained at 0 and 30 minutes at baseline. ResultsThirty subjects out of 140 subjects (21.4%) developed type 2 diabetes. When insulin-based index and C-peptide-based index are compared between progressor and non-progressor to diabetes, all C-peptide-based indices were statistically different between two groups, but only insulinogenic index and disposition index among insulin-based index were statistically different. C-peptide-based index had higher value of area under receiver operating characteristic curve (AROC) value than that of insulin-based index. "C-peptidogenic" index had highest AROC value among indices (AROC, 0.850; 95% confidence interval, 0.761 to 0.915). C-peptidogenic index had significantly higher AROC than insulinogenic index (0.850 vs. 0.731 respectively; P=0.014). ConclusionC-peptide-based index was more closely related to incident type 2 diabetes in non-diabetic subjects than insulin-based index.

- Background
Serum albumin has been suggested to be associated with insulin resistance. We evaluated the association between serum albumin concentration and insulin resistance. We also investigated whether serum albumin level has an independent effect on the development of diabetes. MethodsIn our study, 9,029 subjects without diabetes, who underwent comprehensive health check-ups annually for 5 years, were categorized into tertiles based on their serum albumin levels at baseline. The odds ratio (OR) for the prevalence of insulin resistance, defined as the top quartile of homeostasis model assessment of insulin resistance and the presence of impaired fasting glucose and nonalcoholic fatty liver disease, was evaluated cross-sectionally. Also, the hazard ratio (HR) for incident diabetes was estimated longitudinally, according to the baseline albumin tertiles using Cox proportional hazard analysis respectively. ResultsFrom the lowest to the highest tertile of albumin, the multivariable-adjusted ORs of insulin resistance increased significantly in both men and women. During the mean follow-up period of nearly 4 years, 556 (6.1%) subjects progressed to diabetes. The multivariable-adjusted HR (95% confidence interval [CI]) of diabetes in men were 1, 1.09 (95% CI, 0.86 to 1.40), and 1.10 (95% CI, 0.86 to 1.41), respectively, from the lowest to the highest tertiles of baseline albumin. Corresponding values for women were 1, 1.21 (95% CI, 0.66 to 2.21), and 1.06 (95% CI, 0.56 to 2.02), respectively. ConclusionOur study showed that increased serum albumin level was associated with insulin resistance. However, serum albumin did not have an independent effect on the development of diabetes.

Abstract

- BACKGROUND
Adipose tissues include multipotent cells, the same as bone marrow-derived mesenchymal stem cells. The stromal vascular fractions (SVFs) from adipose tissues represent a heterogeneous cell population. The purpose of this study was to isolate and purify adipose-derived stem cells (ASCs) in SVFs by the density gradient method. METHODS: SVFs were extracted from the subcutaneous, epididymal, mesenteric and retroperitoneal adipose tissue of 8 weeks old male Sprague-Dawley rats (n = 15) and these were separated into 4 layers according to a Nycodenz gradient (Fx-1: < 11%, Fx-2: 11-13%, Fx-3: 13-19% and Fx-4: 19-30%). The post-confluent SVFs were cultured in adipogenic medium for 2 days, in insulin medium for 2 days and in 10% fetal bovine serum medium for 5 days. To observe lipid droplets in SVFs, we performed Oil Red O staining. RESLTS: The SVFs' cellular fractions (Fx-1, Fx-2, Fx-3 and Fx-4) were isolated by density gradient centrifugation from the adipose tissues of rats. The SVFs extracted to fraction 3 (Fx-3) had the most abundant cells compared to that of the other fractions. However fraction 1 (Fx-1) or 2 (Fx-2) had a superior ability to make lipid droplets. The adipogenic differentiation of Fx-1 or 2 was higher than that of the unfractionated cells. The SVFs extracted from retroperitoneal adipose tissue had the highest efficiency for adipogenic differentiation, whereas the SVFs from mesenteric adipose tissue did not differentiate. CONCLUSION: This density gradient fractionated method leads to efficient isolation and purification of cells with the characteristics of ASCs.

Abstract

- BACKGROUND
Recent studies suggest a possible pathogenic linkage between the osteoporosis and atherosclerosis. We investigated the relationship between cardiovascular risk factors, including high sensitivity C-reactive protein (hs-CRP), insulin resistance, lipid profiles and bone metabolism in Korean females. METHODS: Anthropometric measurements were performed on 437 women (mean age 52 yrs), and cardiovascular risk factors, including fasting blood glucose, fasting blood insulin, lipid profiles and hs-CRP, measured. An atherogenic index was calculated using the serum total cholesterol level divided by the high-density lipoprotein cholesterol (HDL-C) level. The lumbar spine bone mineral density (BMD) was measured using dual X-ray absorptiometry. RESULTS: From bivariate analyses, the lumbar spine BMD showed negative correlations with age, systolic and diastolic blood pressures, serum total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglyceride levels and atherogenic index, and a positive correlation with the HDL-C level. After adjustment for age and BMI, the atherogenic index and HDL-C showed consistent correlation with the lumbar spine BMD. The log-transformed hs-CRP showed no correlation with the lumbar spine BMD. In premenopausal women, age, BMI and atherogenic index showed significant associations with the lumbar spine BMD and the atherogenic index showed consistently significant correlation, even after adjustment for age and BMI. In postmenopausal women, only age and BMI showed significant correlations with the lumbar spine BMD. From multiple linear regression analyses of all the study subjects, age, BMI, atherogenic index and the presence of menopause were found to be determinants of the lumbar spine BMD (R2 = 0.422, p < 0.05), which was consistently significant in analysis performed on premenopausal women (R2 = 0.157, P < 0.05). In postmenopausal women, age and BMI were found to be the determinants of the lumbar spine BMD (R2 = 0.257, P < 0.05). CONCLUSIONS: The lumbar spine BMD was negatively correlated with the atherogenic index in all and in premenopausal women. The menopause seems to play an important role in the relationship of cardiovascular risk factors with BMD in Korean females.

Abstract

- BACKGROUND
In spite of the increasing information that has recently been accumulated on the involvement of ghrelin and leptin in energy balance control, the relationship between ghrelin or leptin and the growth hormone (GH)-Insulin like growth factor-1 (IGF-1) axis in the pathological condition characterized by growth hormone deficiency (GHD) has been poorly clarified. Therefore, we performed this study to evaluate the correlation of the plasma levels of ghrelin and leptin with the anthropometric and biochemical markers in GHD adults and also in healthy adults. METHODS: For the 60 male adults (GHD, n = 12; healthy control, n = 48; average age, 54 years), we investigated the correlations between the serum leptin and ghrelin levels with the anthropometric and biochemical factors in the two groups, as divided by their GH status. The diagnosis of GHD was made on the basis of a peak response for serum GH of less than 5 micro/L to a GH provocative test (L-dopa test). All the subjects underwent assessment of waist circumference, BMI and percentage body fat for their body composition. The plasma ghrelin, leptin, insulin, GH and IGF-1 were measured. RESULTS: The groups were well-matched for their age, BMI, waist circumference and percentage of body fat. The ghrelin and leptin levels were not significantly different between the two groups. There was no correlation between the peak GH level or the area under the curve of growth hormone (GHAUC) and the ghrelin concentrations in the GHD subjects. Plasma leptin correlated positively with the percentage of body fat, the total cholesterol and the LDL-cholesterol, but it had no correlation with the peak GH or GHAUC in the GHD subjects. CONCLUSIONS: It is possible that the ghrelin concentrations appeared normal in the GHD subjects. Further studies are needed to clarify these controversies about the relation of ghrelin and leptin with the GH and IGF-1 levels.

- BACKGROUND
Osteoprotegerin(OPG) is a recently identified cytokine, which acts as a decoy receptor for the receptor activator of the NF-kappaB ligand(RANKL), and has also been shown to be an important inhibitor of osteoclastogenesis in animal models. However, the relationship between OPG gene polymorphism and female bone stati in human populations is unclear. In this study, the relationship between OPG gene polymorphisms and bone mineral metabolism in healthy Korean women was investigated. METHODS: We observed 251 healthy women(mean age, 51.3+/-6.9 yr). The serum OPG concentrations were determined using ELISA, and the biochemical markers of bone turnover and FSH measured using standard methods. The bone mineral densities at the lumbar spine and femoral neck were measured by dual energy x-ray absorptiometry. The A163G, G209A, T245G and T950C polymorphisms of the OPG gene were analyzed by allelic discrimination using the 5 nuclease polymerase chain reaction assay. RESULTS: The lumbar spine BMD of premenopausal women was marginally decreased in the variant allele group compared to the wild type group(A163G, 0.98+/-0.14g/cm2[GG+GA] vs. 1.05+/- 0.15g/cm2[AA], P =0.070; T245G, 0.97+/-0.13g/cm2[GG+GT] vs. 1.04+/-0.15g/cm2[TT], P=0.056). In the linkage of polymorphisms A163G and T245G, the lumbar spine BMD of premenopausal women was marginally decreased in the variant allele group compared to the wild type group([AATT] vs. [AGTG+AGGG+GGTG+GGGG]: 1.04+/-0.15 vs. 0.97+/- 0.13; P=0.072). However, there were no differences in the serum OPG levels and bone turnover markers among the different genotypes. CONCLUSION: The A163G and T245G polymorphisms of the OPG gene were observed to be marginally associated with the lumbar spine BMD in healthy premenopausal Korean women, but further studies will be needed to clarify this relationship

- BACKGROUND
Osteoprotegerin(OPG) is a recently identified cytokine, which acts as a decoy receptor for the receptor activator of NF-B ligand(RANKL). OPG has been shown to be an important inhibitor of osteoclastogenesis and arterial calcification in animal models. Recently, OPG has been proposed as a link molecule between osteoporosis and arterial calcification. However, the relationship between circulating OPG levels and cardiovascular disease in human populations is unclear. Thus, the aim of this study was to investigate the relationship between circulating OPG levels and cardiovascular risk factors in women. METHODS: The subjects were 286 women, with a mean age of 51.5 yr. The blood pressure, body mass index(BMI) and waist to hip ratio(WHR) were examined and the serum concentrations of OPG determined by ELISA. The fasting glucose levels, serum lipid profiles and follicle stimulating hormone (FSH) were measured by standard methods. RESULTS: A significant association was observed between the serum OPG levels, age and WHR(r=0.134, P<0.05). Also, the serum OPG levels were significantly correlated with the serum total cholesterol and low density lipoprotein cholesterol levels(r=0.175, P<0.01; r=0.176, P<0.01). Conversely, there was a nonsignificant relationship between the serum OPG levels, blood pressure and fasting glucose levels. The mean serum OPG levels were found to be about 11% greater in post-than premenopausal women(mean+/-SD, 1358.5+/-380.0 vs. 1228.8+/-407.7pg/mL, respectively(P<0.001). There was a significant association between the serum OPG and serum FSH levels(r=0.176, P<0.01). CONCLUSION: In conclusion, our data show that the levels of circulating OPG are partially associated with the cardiovascular risk factors and female hormonal status in healthy women. These data suggest that OPG may be an important paracrine factor of cardiovascular disease in human female populations.

- BACKGROUND
Fat mass is an important determinant of bone mineral density (BMD), but the mechanism involved in this relationship is uncertain. Several lines of evidence have suggested the effects of fat mass on BMD may be mediated by hormonal factors, with the principal candidates being serum sex hormones, insulin, leptin and adiponectin. Thus, the aim of this study was to investigate the relationship between the serum adipocytokine and ghrelin levels, and BMD in men. METHODS: Eighty men, aged 42~70 (mean age, 54.5 yr), were selected as the study subjects. The serum concentrations of leptin and ghrelin were measured with RIA, the adiponectin with ELISA and the resistin with EIA. The serum concentrations of estradiol, total testosterone and the biochemical markers of bone turnover were measured by standard methods. The BMD at the lumbar spine and femoral neck were measured by dual energy x-ray absorptiometry. RESULTS: The serum leptin level was found to correlate to the BMI, waist to hip ratio (WHR), blood pressure, fasting blood sugar, serum fasting insulin, total cholesterol, triglyceride and calcium levels. Although the serum leptin level was not significantly correlated to the serum estradiol level, it did show a weak trend. The serum adiponectin level were correlated to the BMI, WHR and serum fasting insulin level; and the resistin to serum total cholesterol and low density lipoprotein cholesterol levels; ghrelin to age, WHR and serum triglyceride levels. A significant negative correlation was observed between the serum resistin level and lumbar spine BMD. Also, there was a significant negative correlation between the serum leptin level and lumbar spine BMD. The above correlations were observed only when the BMI and the serum estradiol and insulin levels were included as independent variables in the regression analysis model. The serum adiponectin level was not significantly correlated with the BMD, either in the presence or absence of the BMI and serum insulin level. CONCLUSION: The serum adipocytokine level was observed to be partly associated with the BMD in men. Therefore, these data suggest that leptin and resistin may play roles in the bone mineral metabolism in men. Further studies are needed to larify this relationship

- BACKGROUND
Osteoporosis is a growing health problem, not only in women, but in men also. Sex hormones and insulin-like growth factor-I (IGF-I) have been shown to be the major determinant in male bone metabolism. Osteoprotegerin (OPG) is a recently identified cytokine, which acts as a decoy receptor for the receptor activator of the NF- B ligand (RANKL). OPG and RANKL have been shown to be important regulators of osteoclastogenesis in animal models. The relationship between the OPG-RANKL system and male bone status in human populations is unclear. The aim of this study was to investigate the relationship between circulating the OPG-RANKL system and bone mineral metabolism in 80 Korean men. METHODS: The subjects of this study were 80 men aged between 42 and 70 (mean age, 54.5 yr). The serum concentrations of OPG and RANKL were measured by ELISA. The serum concentrations of estradiol, total testosterone, IGF-I and biochemical markers of bone turnover were measured by standard methods. The bone mineral densites (BMD) at the lumbar spine and femoral neck were measured by dual energy x-ray absorptiometry. RESULTS: A significant correlation was observed between the serum OPG/RANKL ratios and osteocalcin levels (r=-0.229, p<0.05). The serum OPG levels were significantly correlated to the femoral neck BMD (r=-0.227, p<0.05). The mean value of the serum OPG was found to be greater in patients with osteoporosis at the femoral neck (mean SD, 4.72.1 pmol/L) than in subjects with a normal BMD (3.30.9 pmol/L, p<0.05). The serum RANKL/OPG ratios were significantly positively correlated to the serum estradiol level (r=0.401, p<0.001). Also, there was a significant negative correlation between the serum OPG and estradiol levels (r=-0.288, p<0.05). In a multiple regression analysis, the BMI, serum OPG and RANKL levels, and the serum IGF-I level were identified as significant predictors of the femoral neck BMD. In another multiple regression analysis, only the serum estradiol level was identified as a significant predictor of the serum OPG level. CONCLUSION: In conclusion, our data show that the serum OPG and RANKL levels are partly associated with bone mineral metabolism, and are related to the endogenous estrogen levels in human male populations. Therefore, the possibility exists that the OPG-RANKL system may be a mediator of the estradiol in male bone metabolism. However, there have been few study published on the relation between the serum OPG and estradiol levels in men. Further studies are needed to clarify this relationship

- BACKGROUND
The peroxisome proliferator-activated receptor (PPAR) is a member of the nuclear receptor family known to be involved in adipocyte differentiation. Recent studies have revealed the inhibitory role of PPAR in osteoblastogenesis, which suggests its possibility as a candidate gene for osteoporosis. The frequency of C161-->T substitution in exon 6 of PPAR was observed in Korean men and the association of different genotypes with bone turnover markers, bone mineral density (BMD) and serum osteoprotegerin (OPG), which play inhibitory roles in osteoclastogenesis, examined. METHODS: In 72 healthy Korean men (mean age 54.5 6.4 yrs; range 42~69 yrs), anthropometric measurements, and lumbar spine and femoral neck BMD, and bone turnover markers, such as alkaline phosphatase (ALP), serum calcium, phosphorus, osteocalcin and cross-linked C-telopeptides of type I collagen (ICTP) measurements were performed. The levels of serum testosterone, estradiol and insulin-like growth factor (IGF-I), and those of serum OPG levels, were measured with a sandwich enzyme-linked immunosorbent assay (ELISA) method. The DNAs were extracted from the samples, and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and the sequencing of the products were performed to confirm the substitution. RESULTS: The allele frequencies were 0.799 and 0.201 for the C and T allele, respectively, which were in Hardy-Weinberg equilibrium (p=0.80). Subjects with the CT genotype were older and those with the T allele showed higher blood pressure levels and lower body mass indices (p<0.05) than those with the CC genotypes. There were no differences in the bone turnover markers between the different genotypes (p>0.05). The levels of serum testosterone, estradiol, IGF-I and OPG were not different among the different genotype groups (p>0.05). The lumbar, femoral neck BMD (g/cm2) and T scores were significantly lower in subjects with T alleles, and those with CT genotypes showed the lowest BMD values (p<0.05). When the subjects were divided into 3 groups, i.e., normal, osteopenic and osteoporotic groups, according to the lumbar spine BMD, the group with the T allele had a significantly higher prevalence of osteopenia and smaller numbers with normal BMD than those with the CC genotype (p=0.032). CONCLUSION: The frequencies of the C161-->T substitution in exon 6 of the PPAR gene in Korean men were similar to those observed in other races, and those with the T alleles showed significantly lower BMD values. These data imply the PPAR gene might be a candidate gene for the pathogenesis of osteoporosis
