Objective The purpose of this study was to examine possible associations of serum levels of cortisol and dehydroepiandrosterone-sulfate (DHEA-S) with psychiatric symptoms in men with chronic schizophrenia.Methods This study involved 120 men with schizophrenia and 110 age-matched healthy controls,and the information of patients were collected on demographic characteristics,age at disease onset,disease duration,positive and negative syndrome scale (PANSS) scores,and history of atypical antipsychotic treatment.Results Serum levels of cortisol and DHEA-S were calculated,as well as the ratios of the two levels.Possible correlations were explored between these levels and psychiatric symptoms before and after antipsychotic treatment.Serum levels of cortisol and DHEA-S levels as well as the ratios of cortisol to DHEA-S levels were more higher in patients than in controls (P ＜ 0.01).Among patients,serum levels of cortisol and DHEA-S were significantly lower after treatment than before (P ＜ 0.01),although the ratios of cortisol to DHEA-S levels remained similar.Serum levels of cortisol,DHEA-S and the ratios of the two levels were positively correlated with the negative symptoms score on the PANSS.Conclusion The pathophysiology of schizophrenia may involve in the spread levels of cortisol and DHEA-S.These levels may serve as biomarkers for diagnosing schizophrenia and monitoring treatment efficacy.

Some hormones changes in women with polycystic ovary syndrome / Монголын Анагаах Ухаан

IntroductionPolycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-age women,affecting an estimated 5-8% of all women in this age group. Clinically, hyperandrogenism, chronicanovulation, central obesity and polycystic ovary can all occur in women with PCOS and may causeof infertility. Dehydroepiandrosterone sulfate is an androgenic hormone which produced from adrenalcortex and recently, there is no any data determined DHEA-S in patients with PCOS.GoalOur study was designed to determine serum DHEA-S and other hormones in women with PCOS.Materials and MethodWe have used a cross-sectional study design and the study included reproductive-age 18 women withPCOS. ELISA test to determine serum DHEA-S and other sexual hormones was analyzed for all of thesewomen.ResultWhen we analyzed ELISA test to determine serum DHEA-S and other sexual hormones, DHEA-S level8.0±2.1 μg/ml, LH level 9,45±4,3 mlU/ml, FSH level 5,04±1,1 mlU/ml, prolactin level 19,78±12,2 ng/ml, E2 hormone level 16,8±8,9pg/ml, testosterone level 0,25±0,1 ng/ml were in women with PCOS,respectively. And LH/FSH ratio was 2:1 in these women. (p=0.001).ConclusionBy the result, serum DHEA-S, LH,

Study of Estradiol, Testosterone and DHEA-S Status in Women After Surgical Menopause.

Aims and Objectives : The study was done to assess the hormones namely Estradiol, Testosterone, and Dehydroepiandrosterone-sulphate (DHEAs) one day before operation and on ninth post-operative day following surgical menopause. Materials and Methods : This is a cross sectional observational study. The study was done amongst the thirty four women aged between 40-48 years with functioning uterus and at least one ovary, not using any exogenous hormone preparations affecting ovarian function for last three months and having at least one menstrual period in three previous months were included in this study. They had under gone hysterectomy with bilateral salpingooophorectomy due to non-ovarian pathology. Fasting venous blood samples were taken one day before operation and on ninth post-operative day of surgical menopause Serum concentration of estradiol, testosterone, and DHEAS were determined. Results : The circulating estradiol level decreased significantly (p = 0.043) from 161 pg/ml preoperatively to 108 pg/ml. on ninth post-operative day after surgical menopause. In spite of reduction in mean testosterone level from 0.11 ng/ml. to 0.09 ng/ml. following surgical menopause, which is statistically insignificant (p = 0.247).There was no significant difference between the serum DHEA-S level before and after surgical menopause. A significant positive correlation was observed between pre-operative circulatory levels of DHEA-S with that of estradiol while there was absence of any significant co-relations corelations between any of the other pairs of values. Conclusion : The circulating estradiol level decreased significantly on ninth day after surgical menopause and significant positive correlation between pre-operative circulatory levels of DHEA-S with that of estradiol, but there was no significant co-relation between post-operative circulating estradiol with that of DHEA-S. Testosterone did not show any significant relation with estradiol neither in pre-operative period nor in post-operative condition.

SOME RESULTS FROM SERUM DEHYDROEPIANDROSTERONE SULFATE HORMONE DETECTION IN REPRODUCTIVE-AGED WOMEN WITH PCOS AND HEALTHY / Шинэ санаа Шинэ нээлт

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-age women, affecting an estimated 5-8% of all women in this age group. Clinically, hyperandrogenism, chronic amenorrhea, central obesity and polycystic ovary can all occur in women with PCOS and may cause of infertility. Dehydroepiandrosterone sulfate is an androgenic hormone produced inadrenal cortex and recently, there is no any data determined DHEA-S in patients with PCOS.Our study was designed to evaluate obesity, central obesity, hirsute grade and infertility and to determine serum DHEA-S hormone in women with PCOS and healthy non-PCOS women.We have used a cross-sectional study design and the study included reproductive-age 36 women, of whom 18 were diagnosed with PCOS and 18 were non-PCOS. Anthropometric components were measured and ELISA test to determine serum DHEA-S hormone was analyzed for all of these women. When we analyzed ELISA test to determine serum DHEA-S hormone, DHEA-S level was2.9±2.0 µg/ ml in non-PCOS reproductive-age women and 8.0±2.1 µg/ml in women with PCOS, respectively (р=0.01). Among the women diagnosed with PCOS had higher incidence of central obesity and grade II hirsute and infertility than healthy women (p=0.001). By the result, higher level of serum DHEA-S in women diagnosed with PCOS may cause of sign of hyperandrogenism such as central obesity, infertility and hirsute.

Tensión arterial y masa corporal en mujeres infértiles con síndrome de ovario poliquístico y su relación con el perfil hormonal / Blood pressure and body mass in infertile women polycystic ovary syndrome and its relation to the profile hormone

Objetivo: Evaluar perfil hormonal, índice de masa corporal y tensión arterial en 40 mujeres infértiles con ovario poliquístico. Métodos: En la consulta del Centro de Atención Integral de la Universidad de Los Andes se valoró talla, peso y tensión arterial. Durante la fase folicular del ciclo menstrual en ellas se midió en sangre las hormonas sexuales e insulina (basal y 2 horas poscarga glucosada) por electroquimioluminiscencia. Resultados: El índice de masa corporal se correlacionó directamente con el valor de tensión arterial sistólica, la relación LH/FSH y la testosterona sérica; e inversamente con las hormonas FSH y PRL. Los datos clínicos y de laboratorio se observaron dentro de los límites de referencia; sin embargo, la testosterona guardó relación directa con LH/FSH, índice de masa corporal y tensión arterial sistólica. Al compararse dos grupos de paciente con base al valor de la mediana poblacional, los grupos masa corporal > 24 kg/m2 y tensión arterial sistólica >120 mmHg mostraron niveles de DHEA-S e insulina (basal y 2 h) más elevados que en mujeres con índice de masa corporal y tensión arterial sistólica más bajos. Conclusiones: Existe correlación entre niveles séricos de andrógenos con sobrepeso e hipertensión arterial por mecanismos etiológicos interrelacionados. Síndrome de ovario poliquístico es de origen multicausal eventualmente con hiperandrogenemia. La falla metabólica debe controlarse en estas pacientes, lo que permitiría bajar el efecto de los andrógenos y favorecer el estado de fertilidad, pero sobre evita a largo plazo complicaciones como obesidad, diabetes mellitus tipo 2 e hipertensión arterial.

Objective: To evaluate hormonal profile, body mass index and blood pressure in 40 infertile women with polycystic ovary. Methods: In the out patien clinic of the Centro de Atencion Integral de la Universidad de Los Andes, height, weight and blood pressure were assessed. During follicular phase of the menstrual cycle in blood of them sex hormones and insulin (basal, 2 hours post glucose load) were measured by electrochemiluminescence. Results: The body mass index was directly correlated with the value of systolic blood pressure, ratio LH/ FSH and testosterone in serum, and it was inversely correlated with the hormones FSH and PRL. Clinical and laboratory data were observed within the reference limits, but kept directly related to testosterone LH / FSH, BMI and systolic blood pressure. When comparing two patient groups based on the value of the population median, body mass groups > 24 kg/m2 and systolic blood pressure > 120 mmHg, they showed levels of DHEA- S and insulin (basal and 2 h) higher than those women with lower values of BMI and systolic blood pressure. Conclusions: There is a correlation between serum androgen levels with overweight and hypertension by aetiological mechanisms interrelated. Polycystic ovary syndrome is multicausal origin eventually with hyperandrogenemia. Metabolic failure should be monitored in these patients, which would lower the effect of androgens and promote fertility status, but prevents long-term complications such as obesity, type 2 diabetes mellitus and high blood pressure.

El DHEAS incrementa la expresión de GluR2/3 y GLUR2 del receptor AMPA en el hipocampo de ratones C57/BL6 / DHEAS increases levels of GluR2/3 and GluR2, AMPA receptor subunits, in C57BL/6 mice hippocampus

El DHEAS es un neuroesteroide con efecto neuromodulador de la transmisión sináptica y en la neuroprotección, sin embargo las vías moleculares a través de las cuales se inducen estos cambiosno están completamente claras. Como varios de los neuroesteroides actúan a través de los recetores ionotrópicos de glutamato, se evaluó el efecto del DHEAS en las subunidades GluR2 y GluR3 del receptor AMPA para esclarecer sus efectos. Con este fin se administró DHEAS o una sustancia control durante 7 días a ratones C57/BL6. La expresión de las subunidades se evaluó por Westernblotting.Los resultados presentados muestran que la administración prolongada de 40mg/kg/día de DHEAS a ratones C57/BL6 produce un incremento en los niveles de proteína de las subunidades GluR2/3 yGluR2 del receptor AMPA en el hipocampo. Dado el papel específico que juega la subunidad GluR2 del receptor AMPA en el control de la entrada de calcio durante los procesos de muerte celular y de plasticidad sináptica, este hallazgo contribuye al estudio de los neuroesteroides como una estrategia terapéutica relevante en enfermedades neurodegenerativas y eventos cerebrovasculares.

Dehydroepiandrosterone sulfate (DHEA-S) is a neurosteroid that has effects such as neuromodulator of synaptic transmission and neuroprotection. The specific signaling pathways for these effects are not elucidated yet. Given that, some neurosteroids act through the activation of ionotropic glutamate receptors, therefore the effect of DHEA-S on the subunits GluR2 and GluR3of the AMPA receptor was evaluated. Either DHEA-S or a control substance was administered to C57/BL6 mice. Subunit expression of the AMPA receptor was analyzed by Western blotting. Results show that long-term DHEA-S administration toC57/BL6 mice, increases the protein levels of the subunits GluR2 and GluR2/3 of the AMPA receptors located in the hippocampus. Due to the role of AMPA receptor, specifically GluR2subunit in the regulation of intracellular calcium levels, cellular apoptosis, and synaptic plasticity, the study of neurosteroids as a therapeutic strategy in neurodegenerative diseases and cerebrovascular events is very relevant.

EFFECTS OF COMBLNED EXERCLSE ON β-AMYLOLD AND DHEAs IN ELDERLY WOMEN / 体力科学

The purpose of this study was to investigate the changes in health related fitness, β-amyloid and dehydroepiandrosterone sulfate (DHEAs) concentration, in elderly women after 12 weeks of combined exercise. Subjects consisted of fourteen elderly women (control : 7, exercise : 7) whose ages were over 75 yrs and mini mental status examination (MMSE) scores were more than 24. The combined exercise program included stretching for 10 minutes, 30 minutes of low impact aerobic exercise at an intensity above 40∼59% of HRR during 1∼6 weeks and 60∼84% of HRR during 7∼12 weeks, and 20 minutes of resistance exercise composed of muscle strengthening and posture correction. The program was conducted 3 times a week for 12 weeks. We found that peakVO₂ and peakVO₂/weight significantly (<i>P</i><.05) increased after combined exercise. Also β-amyloid significantly (<i>P</i><.05) decreased and DHEAs concentration significantly (<i>P</i><lated with a change in peakVO₂ (r=−0.929, <i>P</i>=0.001) and positively correlated with a change in LDL-C (r=0.799, <i>P</i>=0.031) in the exercise group. The change in DHEAs positively correlated with a change in peakVO₂ (r=0.705, <i>P</i>=0.017) in the exercise group. In conclusion, these results suggest that combined exercise in elderly women (mean age of 75-years) for 12 weeks would play a positive role in cardiopulmonary function, lipid metabolism and dementia risk factors such as β-amyloid and DHEAs.

Determination of Dehydroisoandrosterone Sulfate in Human Plasma by LC-MS / 中国药房

OBJECTIVE:To determine the concentration of dehydroisoandrosterone sulfate (DHEAS) in human plasma by LC-MS.METHODS:With estrogen sulfate (ES) served as an internal standard,the plasma samples were deproteinized with acetonitrile,extracted by solid phase,hydrolyzed and derivatized.Then the concentration of DHEAS was determined by HPLC-MSD on Agilent SB C18 with column temperature kept at 40℃.The mobile phase consisted of acetonitrile-water (in gradient elution).Atmosphere pressure chemical ion source in negative ion detection model was employed.The ions selected for SIM (selected ion monitoring) quantitative analysis included m/z 490.0 (DHEAS ) and m/z 472.1(ES)[M-H]-.RESULTS:The linear range of DHEAS was 250.0～320.0 ng?mL-1(r=0.999 4).The extraction recovery of the simulated human albumin samples ranged from 71.1%～78.9% and its relative recovery ranged from 98.3%～101.4%.Both the intra-day RSD and inter-day RSD were less than 10%.The mean concentration of DHEAS in 15 health aged male volunteers was (981.6?353.4) ng?mL-1.CONCLUSION:The method is simple,practical,accurate and sensitive,and it is applicable for the determination of plasma concentration of DHEAS.

The Relationship between Serum DHEA-s Level and TAS in Healthy Adults

BACKGROUND: DHEA is the most abundant steroid hormone secreted from the adrenal cortex and has several roles such as increasing insulin sensitivity, lowering serum lipid, improving obesity, and anti-cancer effects. DHEA levels vary profoundly and levels decline as age increases. But the role of DHEA in the aging process is not yet fully understood. TAS which provides information of one's antioxidant capacity, also decreases with age. In this study, we investigated the relationship between TAS and serum DHEA-s concentration. METHODS: By reviewing the medical records of 197 healthy adults, we determined the serum levels of DHEA-s and TAS according to BMI, pulse pressure, WBC, hs-CRP, A/G ratio, LDL-cholesterol, triglyceride, ferritin, uric acid and total bilirubin. We studied the relationship between the parameters by Pearson correlation coefficients and multiple regression analysis. RESULTS: The mean level for TAS and serum DHEA-s was 1.20 mml/L and 177.3 ug/mL, respectively. Serum DHEA-s correlated positively with TAS (r=0.44) and negatively for age (r=-0.44). WBC triglyceride and uric acid also showed statistically significant correlations. But, according to multiple regression analysis DHEA-s only correlated with TAS and age. CONCLUSION: Serum DHEA-s correlates positively with TAS.

The Study about the change of Fetal Adrenal Gland Hormone during Pregnancy and Labor / 대한산부인과학회잡지

OBJECTIVE: Fetal adrenal gland hormone was known to have close association with fetal weight and labor pain in response to fetal stress. Our purpose was to analyze the correlation between cortisol, DHEA-S in cord blood and obstetric status of fetuses. METHODS: We collected cord blood samples from 60 neonates immediately after delivery of baby. Six cases were complicated by intrauterine growth restriction and fourteen patients were complicated by preeclampsia. We measured cortisol, DHEA-S levels by using the RIA commercial Kits for the ELISA. We performed statistic analysis of the data on the SPSS computer program. RESULTS: Cortisol was significantly higher in intrauterine growth restriction (23.4 +/- 16.2 microgram/dL) statistically than control group (13.7 +/- 9.5 microgram/dL) (P=0.022). Cortisol and DHEA-S had negative correlation each other (P=0.025). DHEA-S was significantly lower in intrauterine growth restriction (1202.2 +/- 1005.9 ng/ mL) than control group (1714.8 +/- 978.6 ng/mL) (P=0.01). DHEA-S had increased with advancing gestational age (P=0.03) and fetal weight (P=0). CONCLUSION: Cord blood cortisol level and DHEA-S level has close association with intrauterine growth restriction and negative correlation with each other.

Relationship between Stress and Dehydroepiandrosterone Sulfate in Umbilical Blood of Pre-birth / 中国心理卫生杂志

Objective:To explore the correlation of stress, coping style and the concentration of dehydroepiandrosterone sulfate in umbilical blood between preterm birth and normal birth.Methods:46 with preterm birth and 42 normal birth controls were assessed with Life Event Scale (LES) and Defense Style Questionnaire (DSQ) at 28th-week of pregnancy. The concentrations of DHEA-s in umbilical blood were determined by ELISA for the two groups. Results:Of the scales of malignant life events (frequency: 1.24?0.74 vs 1.04?0.03; strength: 56.21?4.03 vs 44.35?1.06)、immature and middle type defense style scales (4.24?0.13 vs 3.55?0.11; 3.86?0.08 vs 3.64?0.06), and DHEA-s (0.72?0.02 vs 0.33?0.03) there were significant difference between preterm birth and normal birth controls (P

Relation of plasma dehydroepiandrosterone sulfate(DHEA-S) to cardiovascular risk factors

BACKGROUND: Few studies have been done regarding the level of DHEA which is influenced by age, and their effect on cardiovascular disease and prevention of cancer. It is a well known fact that the level of DHEA is decreased with age and the aging is not a correctable risk factor for cardiovascular disease. The aim of this study was to identify plasma DHEA-S change by age and to find out if there was any correlation with serum DHEA-S and cardiovascular risk factors. METHODS: The author collected blood from 85 males and 80 females who had no particular disease history and no specific findings on physical examination. If there were any changes of DHEA according to age, we analyzed the correlation of DHEA with cardiovascular risk factors such as blood pressure, total cholesterol, triglyceride, low density lipoprotein, high density lipoprotein and obesity index (body mass index, waist/hip ratio). RESULTS: In both males and females, plasma DHEA-S level peaked at third dacades and the concentration of DHEA was significantly decreased according to aging (p<0.01). In males, DHEA-S showed no correlations with cardiovascular risk factors. In females, DHEA-S showed negative correlations with systolic blood pressure, diastolic blood pressure, total cholesterol, and low density lipoprotein. Also, high density lipoprotein positively correlated with DHEA-S. These correlations in female subjects, however, disappeared after multiple regression analysis. CONCLUSION: In both males and females, plasma DHEA-S was significantly decreased with advancing age. There was no significant correlation between DHEA-S and cardiovascular risk factors in both men and women.

A Change of Adrenal Androgen and Cortisol in Kawasaki Disease

PURPOSE: Endocrine and immune systems are connected and interdependent. Adrenal glands play an important role in this network and control the balance between serum levels of dehydroepiandrosterone sulfate(DHEAS) and cortisol. These steroids have an antagonistic effect on the T cell progression into Th1 and Th2 cells and on the induction of correlated interleukins. Therefore we evaluated the role of adrenal androgen and cortisol as immune modulators in Kawasaki disease(KD) with changes of T cell immunity. METHODS: From April to August in 2001, we examined serum DHEAS and 24 hour urine free cortisol(F) before administration of immunoglobulin and steroids by radioimmunoassay in 14 KD patients. It's clinical severity was determined by Harada score and coronary lesion. RESULTS:The age of the patient group ranged from 4 months to 4 years; its average age was 2.3 years. Three patients(21.4%) were below 1 year, 2(14.3%) between 1 and 2 years, 5(35.7%) between 2 and 3 years, 4(28.6%) between 3 and 4 years of age. Male to female ratio was 1:1.3. DHEAS was significantly decreased in patients(11.1+/-6.0 ng/dL) more than controls(81.6+/-13.3 ng/dL)(P<0.05). Twenty-four hour urine free cortisol was significantly increased in patients(36.9+/-21.9 ng/dL) more than controls(13.6+/-5.5 ng/dL)(P<0.05). Ratio of DHEAS/F was decreased remarkably in patients(0.33+/-0.20) more than controls(6.65+/-2.56)(P=0.016). There was no difference between ratio of DHEAS/F and Harada score, but its ratio was very low in patients with coronary aneurysm. CONCLUSION: These data demonstrate that there are changes of DHEAS and cortisol in acute stage of KD and the dis-equilibrium between two steroids may be relevant in the T cell immune response induction of Kawasaki disease. These changes support the use of DHEAS/F ratio as one of the predictive factors of coronary arteries complication.

Dehydroepiandrosterone sulphate (DHEAS) levels in premenopausal women with systemic lupus erythematosus / 대한류마티스학회지

OBJECTIVE: Dehydroepiandrosterone sulphate (DHEAS), the major steroidal product of the human adrenal, is abnormally low in patients with SLE. Moreover, a recent study confirms a positive effect of the precursor DHEA on the disease course in SLE, which supports an etiologically important role of the hormone on SLE. The aim of this study is to search for an interrelation between clinical manifestations, laboratory findings, and disease activities and DHEAS in patients with SLE. METHOD: DHEAS were measured by radioimmunoassay kit using 125I-labeled DHEA-SO4 antibody-coated tube in the serum of 48 patients with SLE and in 46 control subjects. Laboratory findings, clinical symptoms, signs and SLE disease activity index (SLEDAI) in SLE patients were evaluated at blood sampling time. RESULTS: DHEAS was lower in patients with SLE compared to controls (45.60+/-42.62 mug/dL vs 101.55+/-56.54 mug/dL, p<0.005). The serum DHEAS levels were significantly negative correlation with SLEDAI (r=-0.333, p<0.05). There were significantly negative correlations between daily steroid dose and DHEAS (r=-0.384, p=0.012), and the amount of steroid used during previous 2 months and DHEAS (r=-0.011, p=0.011). CONCLUSIONS: Patients with SLE have low levels of DHEAS and significant negative correlation between SLEDAI, steroid dose and DHEAS.

Fetal Plasma Cortisol and Dehydroepiandrosterone Sulfate in Pregnancy and Term Parturition / 대한산부인과학회잡지

OBJECTIVE: The role of steroid hormones in the control of human parturition has been a subject of debate. The objective of the study was to examine if changes in fetal plasma cortisol or dehydroepiandrosterone sulfate (DHEA-S) are associated with human term parturition. METHODS: Fetal plasma cortisol and DHEA-S were measured in 374 singleton pregnancies delivered at term. Umbilical cord blood was obtained from patients in the following 6 groups: 1) preterm gestations undergoing cordocentesis for clinical indications before 36 weeks of gestation (n=93), 2) women undergoing cordocentesis for clinical indications after 36 weeks of gestation (n=9), 3) elective cesarean section (C/S) at term without labor (n=140), 4) C/S at term with early labor (cervical dilatationp36 weeks) but did not increase during active labor; 4) The cortisol/ DHEA-S ratio (stress index) increased with advancing gestation and with active labor at term. CONCLUSION: Human parturition at term is associated with an increase in fetal plasma cortisol and cortisol/DHEA-S ratio, but not DHEA-S.

The Clitoral Size of the Korean Female Newborn and the Relationship in Clitoral Hypertrophy and Androgen levels / 대한산부인과학회잡지

OBJECTIVE: To determine clitoral size of Korean newborn and androgen hormone levels in clitomegalic newborn. METHODS: The clitoral sizes of 236 Korean female newborn and mother were measured from January in 2000 to March in 2001. Androgen hormone levels were obtained in 11 infants with clitomegaly in order to evaluate the relationship between clitoral hypertrophy and androgen levels. RESULTS: The mean clitoral size of the 236 newborn was 3.82+/-1.47 mm in length and 2.95+/-1.79 mm in width. The mean clitoral size of the 236 postpartum women was 15.8+/-1.03 mm in length and 3.27+/-1.12 mm in width. In the premature infants the clitoral length and width were 4.45+/-1.79 mm and 3.53+/-1.51 mm respectively. In the normal birth weight infants they were 3.70+/-0.75 mm and 2.02+/-0.84 mm respectively. In clitomegalic infants the clitoral size was 5.8+/-0.7 mm in length and 3.7+/-0.4 mm in width. The serum testosterone level was 1.620+/-0.015 nmol/L and dihydrotestoteronesulfate (DHEAS) level 8.44+/-0.01 nmol/L. CONCLUSION: There was no significant correlation between gestational age and clitoral size, but significant negative correlation was found between birth weight and clitoral size. In 11 clito-magalic infants serum androgen was normal level. Also, there was no different clitoral size between clitomagalic infant mothers and normal infant mothers. These RESULTS: suggest that there would be no significant correlation between infantile clitomegaly and androgen level.

Clinical Features and Serum Dehydroepiandrosterone Sulfate and Total Testosterone Levels in Female Patients with Androgenetic Alopecia / 대한피부과학회지

BACKGROUND: The development of androgenetic alopecia is thought to be caused by increased androgen action on the hair follicles in the genetically predisposed person. Although most reports about dehydroepiandrosterone sulfate(DHEA-S) and total testosterone in female androgenetic patients are within normal limits, there are some controversies about comparing the mean values of the patients with those of the normal control group. OBJECTIVE: The purpose of this study was to compare the mean value of plasma DHEA-S and total testosterone of the patients with those of normal controls according to their ages, and evaluate relations between hormone levels and clinical type and hyperandrogenic symptoms(HAS). METHOD: We examined 60 female patients with androgenetic alopecia for clinical types, symptoms, family histories, and other systemic diseases. The mean value of the patients were compared with those of 42 normal controls according to ages, clinical types, and HAS. RESULTS: 1. Forty two cases(70.0%) were Ludwig type I, 16 cases(26.7%) were type II, 2 cases(3.3%) were type III. 26 cases(43.3%) were between 20-29 years, 19 cases(31.7%) were between 30-39 years. 2. Common age of onset was between 20-29years(23 cases, 38.3%) and below 19 years old(21 cases, 35.0%). 3. There were 32 cases(53.3%) who showed HAS and seborrhea was the most common symptom (20 cases). 4. There were 33 cases(55.0%) who showed a family history and the father was the most common relative(19 cases). Family history of first degree relative was 31 cases(51.7%). 5. Plasma DHEA-S levels of both patients and control group were all within normal limits, and there were no significant differences in the mean values between the patients ( 1633.03+/-736.31 ng/ml) and normal controls(1764.72+/-690.94 ng/ml). There were also no difference between the patients and controls according to their ages. 6. In total testosterone, 7 out of 60 patients and 3 out of 42 normal controls were beyond the normal limit and there were no significant differences in the mean values between the patients(0.548+/-0.386 ng/ml) and normal controls(0.563+/-0.501 ng/ml). There were also no differences between the patients and controls according to their ages. 7. There was no significant difference in the mean value of DHEA-S and total testosterone among type I, types II & III, and normal controls. 8. There was no significant difference in the mean value of DHEA-S and total testosterone among patients with HAS, without HAS, and normal controls. CONCLUSION: There were no significant differences in the mean values of plasma DHEA-S and total testosterone between the patients and normal controls and no significant differences in the mean values of hormone levels according to clinical type and HAS.

Relationship of Dehydroepiandrosterone Sulfate, Sex Hormone Binding Globulin and Carotid Atherosclerosis in Women / 대한내분비학회지

BACKGROUND: Cardiovascular disease is the major cause of morbidity and mortality. It is well known that androgen and sex hormone-binding globulin(SHBG) in women were associated with risk factors for cardiovascular disease such as obesity, central fat accumulation and atherogenic lipid profile. High resolution B-mode ultrasonography can visualize directly both luminal and vessel wall characteristics, and ultrasonic measurement of carotid intima-medial thickness(IMT) can be used to investigate the atherosclerosis of coronary, cerebral and peripheral arteries. The aim of this study was to evaluate the relationship between the serum dehydroepiandrosterone sulfate(DHEA-S) and SHBG, and body fat distribution pattern, cardiovascular risk factor and carotid atherosclerosis in women. METHODS: Blood pressure, fasting serum glucose, insulin, lipid profile, SHBG and DHEA-S were measured. Body fat distribution pattern was assessed by waist to hip ratio, waist to thigh ratio and subscapular to triceps skin fold thickness ratio, faf mass measured by bioelectric impedance analyzer, subcutaneous fat area, visceral fat area, and visceral to subcutaneous fat area ratio(VSR) at the level of umbilicus using the computed tomography. The IMT of the carotid artery was measured by high resolution B mode ultrasound as a marker of atherosclerosis. RESULTS: 1) There was no significant difference of age-adjusted values of carotid IMT among subjects with NGT(0.426+/-0.09mm), IGT(0.46+/-10.09mm) and NIDDM(0.453+/-0.11mm). 2) In postrnenopausal women, carotid IMT was greater(0.484+/-0.11mm, p=0.05) than premenopausal women(0.426+/-0.08mm), but it was not significant after age adjustment. Serum SHBG and DHEA-S levels in postmenopausal women were significantly lower(p<0.05) than premenopausal women, but they were not significant after age adjustment. 3) Carotid IMT was significantly correlated with age(r=0.37, p<0.01), fasting serum glucose (r=0.32, p<0.01), total cholesterol(r= 0.25, p<0.05), LDL-cholesterol(r=0.26, p<0.05), visceral fat area(r=0.35, p<0.01) and VSR(r=0.31, p<0.05). 4) By the stepwise multiple regression analysis, carotid IMT was positively and significantly associated with age(p<0.01) and serum DHEA-S concentration(p<0.05) in dent of age, body mass index, waist to hip ratio, fasting serum glucose. CONCLUSION: Carotid IMT was associated with age and serum DHEA-S concentration in women without cardiovascular disease. Therefore, serum DHEA-S may be one of risk factors for cardiovascular disease in women. However, we could not conclude its cause-result relationship because of cross sectional nature of our study, and prospective study will be needed.

Age Changes and Sex Differences in Serum Dehydroepiandrosterone Sulfate (DHEAS) Concentrations & its related factors throughout Adulthood

BACKGROUND : DHEAS, the major circulating adrenal hormone, has been suggested to have a role in many aging related diseases and perhaps in aging itself. But, there is no epidemiologic data of DHEAS in normal adults in Korea. We studied age changes and sex differences in serum DHEAS & its related factors throughout adulthood. METHODS : We administ structured questionnaires to the study subjects. We measured serum DHEAS levels and several biochemical markers (total cholesterol, triglyceride, HDL-cholesterol, glucose etc) in 1.710 healthy men(857) and women (853), aged 17-76 years. We also measured their height, weight, waist & hip circumference and body fat contents with bioimpedance method. We analyzed various variables relating to serum DHEAS levels by using SPSS. Reference data of serum DHEAS level in normal adults were also suggested. RESULTS : The DHEAS concentration peaked at age group blow age of 30 years in man(260.9 microgram/dL). Then mean values declined steadily in both sexes (r=-0.38, por=2 times/week, 219.1 vs 185.3 microgram/dL, p0.85, 227.1 vs 197.4 microgram/dL) after adjusting age. DHEAS was positively correlated with body mass index (r=0.12, p<0.01). But in women, drinkers (154.3 vs 131.7 microgram/dL, p<0.05) and regular exercise group (146.1 vs 131.6 microgram/dL, p=0.05) had higher mean DHEAS value. There were no significant association between DHEAS and lipid profile (total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol) & fasting glucose level in both sex. CONCLUSION : Our data suggest that DHEAS levels may influenced by several sociodemographic factors (e.g. smoking, alcohol, exercise etc) and body mass index. DHEAS level was inversely correlated by age in both sex and men had 1.5 times higher DHEAS values than women. We could not find any association between DHEAS level and lipid profile & fasting blood sugar.
