Two steroids were identified in a supplement named D-2 following the detection of unknown compounds during the routine testing of an athlete's sample. The main glucuroconjugated metabolites were isolated from this urine by high performance liquid chromatography (HPLC) following enzymatic hydrolysis and identified by gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) analyses as being 2α-hydroxy-5α-androst-3-en-17-one (M1) and 2β,3α-dihydroxy-5α-androstan-17-one (M2). A third metabolite, 3α,4β-dihydroxy-5α-androstan-17-one (M3) was also detected, however in lower amounts. The precursor steroids, 5α-androst-2-en-17-one (1) and 5α-androst-3-en-17-one (2) were present in the first D-2 products offered on the Internet. Later, the corresponding 17-hydroxyl compounds were offered as such or as esters (acetate, cypionate) in different relative ratios. Both M2 and M3 were synthesized from the trans-diaxial hydrolysis of the corresponding 2α,3α- and 3α,4α-epoxides (3). These were excreted in the hours following the controlled administration of the commercial product called D-2 R to a male volunteer and were also produced from the incubation of 1 and 2 with S9 liver fractions. Some preparations contain predominantly the alkene in C-2 and, therefore, an efficient detection method must include both primary metabolites M1 and M2. The latter was found equally in the fractions extracted following the enzymatic hydrolysis with β-glucuronidase and the chemical solvolysis, which may ease its identification.

This cohort study of primiparae was conducted to answer the following questions: Do older (≧ 35 years) and younger (20-29 years) Japanese primiparous mothers differ when comparing biomarkers of stress and measures of fatigue and depression? Are there changes in fatigue, depression and stress biomarkers when comparing older and younger mothers during the postpartum period? The Postnatal Accumulated Fatigue Scale and the Edinburgh Postnatal Depression Scale were administered in a time-series method four times: shortly after birth and monthly afterwards. Assays to measure biomarkers of stress, urinary 17-ketosteroids, urinary 17-hydroxycorticosteroids and salivary chromogranin-A, were collected shortly after delivery and at 1 month postpartum in both groups and a third time in older mothers at the 4th month. Statistical testing showed very little difference in fatigue, depression or stress biomarkers between older and younger mothers shortly after birth or 1 month later. Accumulated fatigue and depression scores of older mothers were highest 1 month after delivery. Additional cohort studies are required to characterize physical/psychological well-being of older Japanese primiparae., (© 2015 Wiley Publishing Asia Pty Ltd.)

We investigated the effects of chronic bilateral sensorineural hearing loss of III-IV degree on the performance of interleukins, immunoglobulins serum and saliva, the functional activity of granulocyte-monocyte cell immunity, evaluated the activity of the hypothalamic-pituitary-adrenal system in children aged 7-11 years. It was found that due to stress activation of the sympathetic-adrenal system the function of granulocytes and monocytes is suppressed, with a predominance of production of anti-inflammatory interleukins. This leads to the dominance of T-helper type 2. Products granulocytes and T-helper type-2 anti-inflammatory interleukins IL-4, IL-5, IL-10, IL-13 leads to the activation of B-cells. Thus, in children 7-11 years of age with congenital bilateral sensorineural hearing loss is a decrease of non-specific humoral immunity dominated type of immune response to increased levels of IgG.

Background: Congenital adrenal hyperplasia is a group of disorders caused by defects in the adrenal steroidogenic pathways. In its most common form, 21-hydroxylase deficiency, patients develop varying degrees of glucocorticoid and mineralocorticoid deficiency as well as androgen excess. Therapy is guided by monitoring clinical parameters as well as adrenal hormone and metabolite concentrations., Content: We review the evidence for clinical and biochemical parameters used in monitoring therapy for congenital adrenal hyperplasia. We discuss the utility of 24-h urine collections for pregnanetriol and 17-ketosteroids as well as serum measurements of 17-hydroxyprogesterone, androstenedione, and testosterone. In addition, we examine the added value of daily hormonal profiles obtained from salivary or blood-spot samples and discuss the limitations of the various assays., Summary: Clinical parameters such as growth velocity and bone age remain the gold standard for monitoring the adequacy of therapy in congenital adrenal hyperplasia. The use of 24-h urine collections for pregnanetriol and 17-ketosteroid may offer an integrated view of adrenal hormone production but target concentrations must be better defined. Random serum hormone measurements are of little value and fluctuate with time of day and timing relative to glucocorticoid administration. Assays of daily hormonal profiles from saliva or blood spots offer a more detailed assessment of therapeutic control, although salivary assays have variable quality.

Objectives: In the present study, the metabolism of steroid hormones has been investigated to determine whether and how xenobiotics like lead (Pb) and polychlorinated biphenyls (PCBs) interfere with steroid hormone biotransformation in humans., Methods: Three groups of subjects were tested for concentration of urinary total steroids, 17-ketosteroids (n = 5), pregnane derivates (n = 6), 17-hydroxycorticosteroids (n = 11) and their sulfonated compounds: 14 workers exposed to lead, with a mean Pb blood concentration (PbB) of 29.21 microg/dl; 15 subjects exposed to PCBs, with a mean PCB blood concentration (PCBB) of 61.69 microg/l; a control group (n = 25)., Results: The urinary concentrations of 17-ketosteroids and 17-hydroxycorticosteroids were significantly lower in the PCB-exposed groups. There were significantly fewer sulfonated 17-hydroxycorticosteroids in the subjects exposed to PCBs as compared to the controls, while the percentage of sulfonated steroids was lower for both 17-ketosteroids and 17-hydroxycorticosteroids in the PCB-exposed subjects, but only for the 17-hydroxycorticosteroids in the group of subjects exposed to Pb (P < 0.05). Pregnane derivate urinary concentrations did not differ between the three groups., Conclusion: Our results suggest that PCBs and Pb act on steroid hormone metabolism with different effects and only partially using the same hormone pathways; they may cause changes in endogenous hormone homeostasis and interfere with the xenobiotic phase II of detoxification. PCBs interfere on a larger number of steroids and cause more significant effects than Pb. It is likely that different mechanisms are involved in steroid hormone metabolism interference.

Isocratic HPLC with potentiometric detection is used for the determination of some 17-ketosteroids (17-KS), e.g., androsterone, dehydroepiandrosterone and estrone, and their respective sulfated conjugates (17-KSS). Glassy carbon or composite electrodes containing a mixture of graphite and poly(vinyl chloride), PVC, were used as substrate electrodes. These substrates were covered either by montmorillonite or potassium tetrakis(p-chlorophenyl) borate containing PVC-based rubber phase membranes. The neutral 17-KS compounds were derivatized with Girard's reagent P (GP) to obtain cationic pyridinium acetohydrazones prior to the HPLC/potentiometric detection assay. No side reactions were observed, and the GP itself was not interfering. The method yielded accurate and reproducible results and was applicable to samples containing down to micromolar concentrations. Next, the 17-KSS compounds, acting as anionic charged molecules, were determined directly in human urine samples with the HPLC/potentiometry combination without preliminary derivatization. For this purpose, a new anion-sensitive potentiometric electrode was developed using a macrocyclic polyamine containing, PVC-based, rubber phase membrane. The three 17-KSS compounds were also determined accurately down to micromolar concentrations. Especially, the main androgen metabolites as dehydroepiandrosterone sulfate and androsterone sulfate could be selectively determined with a developed potentiometric sensor in human urine samples without time-consuming cleanup and preconcentration step.

Concurrent methods for identification of urine as being of human origin, and for DNA-typing from small stains of human urine were examined. A urine stain was extracted with phosphate-buffered saline (PBS), and the extract was filtered using a Centricon-100 device. The filtrate was subjected to electrospray ionization liquid chromatography-mass spectrometry (ESI-LC-MS) for identification of human urine and a DNA-typing sample was obtained by dialfiltration of the residue using a DNA purification kit. After the purified residue was treated with an AmpflSTR Profiler PCR amplification kit, the DNA-types were analyzed by capillary electrophoresis using a Genetic Analyzer. It was possible to identify a urine stain as being of human origin, and complete DNA profiles could be successfully obtained from a urine stain which had been created by 50 microL of female urine. Serial analyses of urine stains found at a crime scene provide effective information for forensic investigation. This method is recommended for stain identification and for DNA-typing from a urine stain.

Stress effects of 3-d (72-hr) continuous vigilance were studied for renal excretion of 17-oxycorticoids (17-KS), electrolytes (potassium and sodium), and liquid. The investigation involved 12 male subjects aged 23 to 36. Baseline parameters displayed diurnal variations with comparatively high day and comparatively low night values. During the 72-hr vigilance, significant and consistent (statistically fiducial) intensification of 17-KS and potassium excretion occurred in the night-time, i.e., in the period of naturally low values, but only in the first two sleepless nights. As for sodium and liquid excretion, stress-related reduction in these parameters was more consistent and distinct in the day-time, i.e., in the period of naturally high values, rather than in the nighttime. Therefore, the two factors that should be accounted for by investigators of continuous vigilance (and, maybe, other stresses) are the anticipated direction of a stress-reaction and baseline diurnal variation of parameters under study. If stress is expected to increase a parameter, measurements should be done when the parameter is naturally low and, vice versa, if stress is known to reduce a parameter, then measurement should be planned in the period when it is naturally high. If direction of stress-related changes is predictable, investigations can be performed on a twenty-four hour basis.

Background: School non-attendance is a major social problem in Japan. Many children stop attending school for a variety of reasons. The authors previously reported stress barometer values for healthy Japanese children. In this study, the authors examined the stress barometer values of children with school non-attendance., Methods: The authors measured stress barometer values, that is, urinary 17-hydroxycorticosteroids (17-OHCS) and 17-ketosteroid sulfates (17-KS-S) in 65 children (40 girls and 25 boys; 7-15 years of age) with school non-attendance, except for pervasive developmental disorder and mental retardation, who attended the outpatient department of Dokkyo University School of Medicine Hospital, Tochigi, Japan, during the past 4 years., Results: A total of 24 (36.9%) of the 65 children had urinary 17-OHCS values above 2SD, and 14 (21.5%) had urinary 17-OHCS below 2SD. In total, 10 (15.4%) children had urinary 17-KS-S values above 2SD, and four (6.2%) had urinary 17-KS-S below 2SD. Five (7.7%) children had urinary 17-KS-S/17-OHCS values above 2SD, and 10 (15.4%) had urinary 17-KS-S/17-OHCS below 2SD., Conclusion: The stress barometer values appear to be clinically useful for evaluating objectively whether children with school non-attendance have emotional stress.

Background: It has been reported recently that fluvoxamine (a selective serotonin reuptake inhibitor) is effective and safe for children with monosymptomatic nocturnal enuresis (MNE). However, the exact mechanism by which fluvoxamine is beneficial in the treatment of MNE remains unknown. One possibility is that it controls emotional stress., Methods: We divided children with MNE into primary MNE (n = 40) and secondary MNE (n = 7). We measured urinary 17-hydroxycorticosteroids (17-OHCS) and 17-ketosteroid sulfates (17-KS-S) as a stress barometer in children with MNE to evaluate adaptation to emotional stress before and during fluvoxamine treatment. We initially administered fluvoxamine at a dose of 25 mg at bedtime. If patients remained incontinent after 3 weeks, we increased the dose to 50 mg., Results: Fluvoxamine was effective in 26 of 28 children (93%) with primary MNE and an abnormality of the stress barometer and in six of six children (100%) with secondary MNE and an abnormality of the stress barometer. Fluvoxamine was effective in only six of 12 children (50%) with primary MNE and normality of the stress barometer and was not effective in one child with secondary MNE and normality of the stress barometer., Conclusions: The stress barometer is useful clinically for evaluating the therapeutic effect of fluvoxamine for children with MNE.

We previously reported that the daily urinary unidentified ketosteroid glucuronide (US-G) level in patients with Cushing's syndrome was much higher than that in the healthy subjects. Furthermore, urine samples from patients with Cushing's syndrome, including those with pituitary adenoma and adrenal adenoma, yielded almost the same high excretion levels, despite the different sites of the adenomas. We extracted US obtained by hydrolysis of US-G in urine of patients with Cushing's syndrome, purified it, and analyzed its chemical structure. Molecular weight and molecular formula were analyzed by MS spectrometry, and the chemical structure was analyzed by NMR spectrometry, utilizing small quantities of refined US. The substance has a molecular weight of 304 Da, a molecular formula of C19H28O3, and its chemical structure is 3alpha,11beta-dihydroxyandrost-4-en-17-one.

DHEA-S (dehydroepiandrosterone sulfate) has many roles in human body as comprehensive vital power, whose metabolite is urine 17-KS-S (abbreviated S), having function of anti-cortisol. The metabolite of cortisol is urine 17-OHCS (abbreviated OH). DHEA-S is produced not only in adrenal glands but in brain. In order to examine the effects of logotherapy, urine S and OH were examined. Subjects were chronic low back pain patients treated by loxoprofen sodium (NSAID). In Group 1 (n = 11) logotherapy was not added, but in Group 2 (n = 10) it was added. Before the treatment, both groups showed low S and high OH. After 3 weeks, Group 2 showed higher S and lower OH than Group 1. After 18 weeks, 4 cases (40%) were relapsed in Group 2, and 10 (90.9%) were in Group 1 (p < 0.05). Group 2 was divided into 2 groups; relapsed group (n = 4) and non-relapsed group (n = 6). S, OH, S/OH were examined between 2 groups of Group 2 and Group 1. Relapsed group of Group 2 and Group 1 showed lower S and higher OH than non-relapsed group of Group 2. [Discussion] Logotherapy is a method to activate comprehensive human vital power. This is the mechanism through stimulating and activating human brain function.

The objective evaluation of Psychoneuroendocrinological effects of music is performed in listening and performing. Subjects were classified into 3 groups; a control group and performance/listening groups voluntarily in each 10 subjects. Urine 17-KS-S (abbreviated S) and 17-OHCS (abbreviated OH) were measured before (phase I), after the experiments (phase II) and on the following morning (phase III). They enjoyed listening to their favorite music by stereo sets or performing favorite music instruments. No directions were done on the quality of music. OH showed decreasing effects in both control and performance/listening groups. S showed significant increase in listening group. From a rise of S/OH a wear and tear by stress and a skewness of balance of restoration were corrected. Music is considered that it contributed to relaxation from stress and a wear and tear by the stress and correction of balance of restoration. The fact that the efficacy persisted until the morning of the following day indicates the efficacy persists for a relatively long period of time.

Feeding 50% ethanolic extract of A. aspera to male rats resulted in reduced sperm counts, weight of epididymis, serum level of testosterone and testicular activity of 3beta-hydroxysteroid dehydrogenase, while motility of the sperm and activity of the HMG CoA reductase were not affected. Cholesterol level in the testis, incorporation of labelled acetate into cholesterol, 17-ketosteroids in urine and hepatic and fecal bile acids were increased. The results suggest that ethanolic extract of A. aspera caused reproductive toxicity in male rats and the action may be by suppressing the synthesis of androgen.

A new method for identifying human urine stains utilizing high-performance liquid chromatographic (HPLC) analysis of five major 17-ketosteroid conjugates: dehydroepiandrosterone sulfate, etiocholanolone sulfate, etiocholanolone glucuronide, androsterone sulfate, and androsterone glucuronide was examined. Samples of urine stains were extracted with borate buffer solution (pH 9.3) and the extracts were applied onto a Sep-Pak tC18 cartridge. The analytes were eluted from the cartridge with methanol. The eluates were prelabeled with 2,4-dinitrophenylhydrazine in trichloroacetic acid-benzene solution and were separated by HPLC on a reversed-phase ODS column using a mobile phase of 80% methanol in a buffer consisting of 25 mM sodium acetate in 2% acetic acid. The eluates were monitored by a spectrophotometer at 380 nm. While all five 17-ketosteroid conjugates were clearly detected in the human urine stain samples, traces of only some of these conjugates were detected in the animal samples. Therefore, the presence of all five 17-ketosteroid conjugates indicated human specificity. In addition to the above finding, the properties of those five 17-ketosteroid conjugates were confirmed by electrospray ionization liquid chromatography-mass spectrometry (ESI-LC-MS).

A small transient increase in growth, the midgrowth spurt, has been observed in several growth studies in healthy children around the age of 7 yr. During this time adrenarche (the physiological increase in adrenal androgen secretion) also occurs. Although it is now well established that estrogen, not androgen, has a critical role in the male (and female) pubertal growth spurt, a direct effect of androgens on growth cannot be excluded. In accordance with published observations that growth is frequently accelerated in infants and young children with late-diagnosed 21-hydroxylase deficiency (before adequate androgen suppression), it has been speculated that the adrenarchal increase in adrenal androgen secretion in healthy children could be responsible for the midgrowth spurt. To test this hypothesis we studied long-term serial changes in urinary 24-h excretion rates of dehydroepiandrosterone sulfate and total 17-ketosteroid sulfates in a group of healthy children (n = 12) in which yearly auxological measurements allowed the identification of a midgrowth spurt. Annual measurements of standing height were performed over periods of 6-9 yr before the onset of puberty. All children collected five to seven serial 24-h urine samples (1-yr intervals) each at the time of anthropometric examination. The peak of the midgrowth spurt was found to occur at a mean age of 6.8 +/- 1.0 yr. The average height of the midgrowth peak, i.e. average maximum gain in height velocity, was 0.9 cm/yr. In a peak-centered examination of individual 24-h excretion rates of dehydroepiandrosterone sulfate and 17-ketosteroid sulfates, primarily weak 1-yr changes in adrenal androgens were observed until the peak was attained. Only after the peak did increments in urinary adrenal androgen output become more pronounced. ANOVA performed on the peak-centered dehydroepiandrosterone sulfate and 17-ketosteroid sulfate excretion rates revealed a highly significant overall increase in adrenal androgen secretion from 2 yr before to 2 yr after the midgrowth spurt. After multiple testing, however, significant increments, when compared with the respective preceding androgen excretion levels, were for the first time seen 1 yr after the midgrowth spurt (dehydroepiandrosterone sulfate) or 2 yr later (17-ketosteroid sulfates). In conclusion, our longitudinal analysis of prepubertal growth and urinary adrenal androgen excretion in healthy children disproves the speculation that the midgrowth spurt is primarily caused by the adrenarchal increase in adrenal androgen secretion. However, the present results do not rule out a growth-accelerating effect of clearly higher androgen levels, as in premature adrenarche.

We measured both urinary 17-hydroxycorticosteroids(17-OHCS) and 17-ketosteroid sulfates(17-KS-S) in normal children and in children with some diseases to evaluate adaptation to stress in children. 17-OHCS and 17-KS-S values were measured in morning urine from 60 normal children(3-18 years old) and 24 children with atopic dermatitis or renal disease. In normal children, the 17-OHCS/creatinine showed no difference by age, but both 17-KS-S/creatinine and 17-KS-S/17-OHCS showed significant positive correlation with age. No sex differences were significant. In children with atopic dermatitis or with renal disease treated with cyclosporine A, 17-OHCS/creatinine was significantly higher and the 17-KS-S/17-OHCS ratio was significantly lower than in age-matched controls. These values returned to normal as the conditions improved or as treatment ended. In patients who underwent renal biopsy, both 17-OHCS/creatinine and 17-KS-S/creatinine values were significantly higher after biopsy than before because of the stress caused by pain and complete bed rest. Measurement of urinary 17-OHCS and 17-KS-S in children can be useful for evaluation of adaptation to stress as well as in adults.

A patient with adrenocortical carcinoma presented with fever, leukocytosis, and increased acute phase reactants. The tumor was infiltrated with neutrophils. Immunohistochemical staining of the tumor showed positive signal for epithelial neutrophil-activating protein-78, an angiogenic and chemotactic CXC chemokine. Conditioned medium from tumor-derived cells (RL-251) showed high concentration of IL-8, epithelial neutrophil-activating protein-78, Gro alpha, and Gro gamma, angiogenic CXC chemokines with a potential role in tumorigenesis. An adrenal cancer/severe combined immunodeficiency mouse chimera was developed. Mice grew tumors rapidly, and circulating levels of IL-8 and epithelial neutrophil-activating protein-78 were detected. In contrast, animals transplanted with NCI-H295 cells, a nonchemokine-secreting cell line, grew tumors more slowly and did not have detectable chemokine levels. Similar to the patient, mice with RL-251 tumors developed marked leukocytosis and neutrophilia, and their tumors were infiltrated with neutrophils. Mice were passively immunized with epithelial neutrophil-activating protein-78 antisera. A marked decrease in tumor growth was observed. Potential for chemokine production by other adrenocortical tumors was investigated by RT-PCR in archival material. Six of seven adrenal carcinomas and one of three adenomas had cDNA for IL-8; six of seven carcinomas and the three adenomas had cDNA for epithelial neutrophil-activating protein-78. We concluded that the clinical presentation of this case resulted from increased tumor production of chemotactic chemokines. Through their angiogenic and chemotactic properties these chemokines may play an important role in adrenal tumorigenesis.

The effects of garlic supplementation on protein metabolism were investigated by measuring testis testosterone and plasma corticosterone in rats fed diets with different protein levels. In Experiment 1, rats were fed experimental diets with different protein levels (40, 25 or 10 g/100 g casein) with or without 0.8 g/100 g garlic powder. After 28 d of feeding, testosterone contents in the testis were significantly higher and plasma corticosterone concentrations were significantly lower in rats fed 40 and 25% casein diets with garlic powder than in those fed the same diets without garlic powder. Urinary excretion of 17-ketosteroid (an index of testosterone), nitrogen balance and hepatic arginase activity were significantly higher in rats fed the 40% casein diet with garlic powder than in the 40% casein controls. In Experiment 2, the effect of diallyldisulfide (a major volatile sulfur-containing compound in garlic) on the secretion of luteinizing hormone (LH) from the pituitary gland, which regulates testosterone production in the testis, was investigated in anesthetized rats. Plasma LH concentration increased dose dependently after administration of diallyldisulfide (P < 0.01, r = 0.558). These results suggest that dietary supplementation with 0.8 g/100 g garlic alters hormones associated with protein anabolism by increasing testicular testosterone and decreasing plasma corticosterone in rats fed a high protein diet.

Transsphenoidal adenomectomy is currently the first choice for treatment of patients with pituitary ACTH-dependent Cushing's syndrome. However, pharmacotherapy is prescribed for some patients, e.g., unsuccessful surgery. We treated a woman in whom pituitary Cushing's syndrome was improved while she was on antimuscarinic cholinergic agents, atropine sulphate and pirenzepine hydrochloride. The diminished effect of anticholinergics on ACTH and cortisol was incidentally identified in an inferior petrosal sinus sampling procedure. A single intramuscular injection of atropine significantly decreased both ACTH (43.9 pg/ml to less than 12.0; normal, 12.0-40.0 pg/ml) and cortisol (29.9 microg/dl to 13.6; normal, 7.6-23.6 microg/dl). An M1-muscarinic receptor specific antagonist, pirenzepine hydrochloride, also had a diminishing effect on these hormones and this inhibiting effect was partially blocked by the simultaneous administration of an anticholinesterase agent, pyridostigmine bromide. Chronic oral ingestion of these agents led to improvement in clinical symptoms, and urinary 17-hydroxycorticosteroid and 17-ketosteroid levels were at normal to upper-normal levels. This is the first documentation of involvement of the cholinergic system in the pathogenesis of pituitary Cushing's syndrome.

Biological cycles with relatively long and some unusual periods in the range of the half-week, the half-year, years, or decades are being discovered. Their prior neglect constituted a confounder in aging and much other research, which then"flew blind" concerning the uncertainties associated with these cycles when they are not assessed. The resolution of more about 10-year and other cycles, some reported herein, replaces the admission of complete unpredictability, implied by using the label "secularity." Heretofore unaccounted-for variability becomes predictable insofar as it proves to be rhythmic and is mapped systematically to serve as a battery of useful reference values. About 10-year cycles in urinary 17-ketosteroid excretion and in heart rate and its variability, among others, are aligned with cycles of similar length in mortality from myocardial infarction. Associations accumulate between cycles of natural physical time structures, chronomes such as the 10.5-year (circadecennian) Schwabe and the 21-year (circavigintunennian) Hale cycles of solar activity, and chronomes in biota. There are about 50-year (circasemicentennian) cycles in mortality from stroke in Minnesota and in the Czech Republic and also in human morphology at birth, the latter result reducing the likelihood that these cycles are purely human made. Associations among large populations warrant long-term systematic coordinated sampling of natural physical and biological variables of interest for the design of countermeasures against already documented elevated risks of stroke, myocardial infarction, and other catastrophic diseases, notably in elderly adults. New findings will be introduced against the background of the documented value of mapping rhythms in medicine and gerontology. In both these fields, rhythms promise the seeming paradox of better care for less.

Objective: To assess whether treatment of virilizing congenital adrenal hyperplasia (CAH) with long-acting glucocorticoids is associated with favorable growth outcomes., Method: We examined the long-term growth of 17 boys and 9 girls with CAH treated with dexamethasone (.27 +/-.01 mg/m(2)/day)., Results: For individuals with comparable bone age (BA) and chronological age (CA) at the onset of dexamethasone therapy, males were 2.8 +/-.8 years (mean +/- standard error of the mean; n = 13) and females were 2.4 +/- 1.0 years (n = 6). Males were treated for 7.3 +/- 1.1 years (DeltaCA) over which time the change in BA (DeltaBA) was 7.0 +/- 1.3 years, and the change in height age (DeltaHA) was 6.9 +/- 1.1 years. Females were treated for 6.8 +/- 1.3 years, over which time the DeltaBA was 6.5 +/- 1.0 years, and the DeltaHA was 6.3 +/-.8 years. During treatment 17 ketosteroid excretion rates were normal for age and 17-hydroxyprogesterone values were 69.6 +/- 18 ng/dL. Testicular enlargement was first detected at 10.7 +/-.8 years and breast tissue at 9.9 +/- 1.2 years. Three boys and 1 girl had final heights of 171. 8 +/- 6 cm and 161 cm, respectively, compared with midparental heights of 176.1 +/- 4.1 cm and 160 cm. Predicted adult heights for 6 other boys and 5 girls were 176.8 +/- 2.0 cm and 161.4 +/- 2.8 cm, respectively, compared with midparental heights of 174.6 +/- 1.4 cm and 158.2 +/- 2.0 cm. Statural outcomes were less favorable for 7 children started on dexamethasone when BAs were considerably advanced, although height predictions increased during therapy., Conclusions: These observations show that children treated with dexamethasone for CAH can achieve normal growth with the convenience of once-a-day dosing in most cases.congenital adrenal hyperplasia, dexamethasone, growth.

An adrenocortical adenoma causing Cushing's syndrome (Cushing's adenoma) produces a unilateral concordant visualization (UCV) imaging pattern in which the adenoma is only visualized on radioiodocholesterol adrenocortical scintigraphy. But because this imaging pattern is also noted in some patients with adrenal incidentalomas, we examined whether the UCV-incidentaloma was essentially identical with Cushing's adenoma and would develop Cushing's syndrome. The subjects were 9 patients with UCV-incidentalomas (mean size, 30 mm; range, 20-45 mm) and 6 patients with Cushing's adenomas (mean size, 28 mm; range, 25-35 mm). Endocrinological evaluations showed several abnormalities including blunted diurnal rhythm of plasma cortisol within the normal range, low plasma ACTH and/or high 24-hr urinary 17-OHCS levels in 8 of 9 patients with UCV-incidentalomas, but these abnormalities did not meet the diagnostic criteria of Cushing's syndrome. Adrenal uptake of the tracer in the patients with UCV-incidentalomas was not statistically different from that in the patients with Cushing's adenomas and had no relationship with hormonal values in either patient group. Tumor size on CT correlated with the levels of 24-hr urinary 17-OHCS (r = 0.75, p = 0.02) and plasma cortisol at 7:00 (r = 0.82, p = 0.007) in the patients with UCV-incidentalomas, but not in the patients with Cushing's adenomas. Although 3 UCV-incidentalomas increased slightly in size, none of 9 patients with UCV-incidentalomas has developed Cushing's syndrome for 4 to 52 months. These results suggest that the UCV-incidentaloma may be essentially different from the Cushing's adenoma and unlikely to develop Cushing's syndrome.

Here we report a case of a renin-producing adrenocortical carcinoma. A 57-year-old woman was referred to our hospital complaining of thirst and generalized muscle weakness. She was diagnosed as being hypertensive and diabetic with associated hypokalemia and she had a hard elastic mass with a diameter of 10 cm on the left side of her neck. An abdominal computed tomography scan revealed a suprarenal mass on the left side (8.5 x 8 x 6.5 cm). Endocrinological examination demonstrated a marked elevation in the patient's serum glucocorticoid and sex steroid hormones as well as plasma renin activity. Histological examination of a sample taken from the neck mass revealed a metastasis from an adrenal carcinoma, which was stained positively with antibodies against cytochrome P450 and renin, establishing the diagnosis of a renin-producing adrenocortical carcinoma. Trilostane was effective in reducing serum cortisol levels, but mitotane was ineffective.

In terms of adaptability, unlike inanimate objects, living organisms exist in a dynamic balance between "wear and tear" and "repair and recovery". We regarded 17-hydroxycorticosteroids (17-OHCS) as a compound related to tissue "wear and tear" (Hans Selye) and sought for a compound related to tissue "repair and recovery". This led us to the discovery of 17-ketosteroid sulfates (17-KS-S) in urine. Elderly persons, unlike young adults, show low levels in 17-KS-S and little diurnal changes. In an elderly person 17-KS-S can decrease on significant life events (e.g. a spouse's death) and remain at low levels for a long time. Elderly persons with frailty need to improve their lifestyle (meals, exercise, rest, sleep, etc.) qualitatively and quantitatively to adapt themselves to stress adequately. Increased 17-KS-S levels were to be related to improvement in lifestyle.

The morning surge in blood pressure (BP) is related to the morning occurrence of lethal cardiovascular events. We tested the hypothesis that salt intake may be associated with the morning surge in BP in essential hypertension. Seventy-six patients were admitted and placed on a low salt diet (2 g/day) for 7 days followed by a high salt diet (20-23 g/day) for another 7 days. At the end of each salt diet, 24-h ambulatory BP and heart rate monitorings and head-up tilt (HUT) test were performed. Patients whose average mean BP (MBP) was increased by more than 10% by salt loading were assigned to the salt-sensitive (SS) group (n = 37); the remaining patients, whose MBP was increased by less than 10%, were assigned to the non-salt-sensitive (NSS) group (n = 39). The increase in ambulatory MBP during 6.30-8.00 am above the baseline (2.00-4.00 am) was significantly enhanced by salt loading in the NSS group (P < 0.05), but not in the SS group. The coefficient of variation of 24-h MBP and heart rate was increased by salt loading only in the NSS group. The significant elevation of plasma noradrenaline concentration after awakening, which was noted during the low salt diet period, was unchanged during the high salt diet period in the NSS group, but abolished in the SS group. Salt loading enhanced HUT-induced decrease in systolic BP without affecting the heart rate response only in the NSS group. We conclude that the morning surge in BP is enhanced by salt loading in the NSS type of essential hyper- tension, presumably by the excessive activation of the sympathetic nervous system.

We report a case of preclinical Cushing's syndrome in a 54-year-old male associated with bilateral adrenocortical tumours. Physical findings and general laboratory data were unremarkable except for mild hypertension (158/90 mmHg) and impaired glucose tolerance. Endocrinological evaluation revealed the presence of autonomous cortisol secretion including unsuppressible serum cortisol by 8 mg dexamethasone test (11 microg/dl), high serum DHEA-S (3580 ng/ml, normal: 400-3500) and increased urinary 17-KS excretion (31.0-35.8 mg/day, normal: 5.8-21.3). CT scan demonstrated the presence of tumours in both adrenals and bilateral adrenalectomy was subsequently performed. Histological examination of the resected specimens revealed an adrenocortical carcinoma on the right side and an adenoma on the left side with noticeable cortical atrophy in non-neoplastic adrenals. Immunohistochemical study of steroidogenic enzymes demonstrated that all the steroidogenic enzymes involved in cortisol biosynthesis were expressed in both right and left adrenal tumours. Enzymatic activities of 21, 17alpha, 18, 11beta-hydroxylases were detected in both right and left adrenals except for the absence of 11beta-hydroxylase activity in the left adrenal adenoma. Results of in vitro tissue steroidogenesis examined in short-term tissue culture of the specimens revealed no significant differences between carcinoma and adenoma in cortisol production, but the production of adrenal androgens in carcinoma was significantly higher than that in adenoma, which may indicate the importance of evaluating adrenal androgen levels in patients with adrenocortical neoplasms.

Urinary DHEA and its metabolites in healthy young female were measured by capillary gas chromatography. The subjects achieved normal pubertal development, and their adrenal DHEA secretions had reached to the stable state. The diurnal variation, fluctuation during the menstrual cycle and seasonal variation of urinary DHEA excretion in each subject were relatively low compared with between-subject variability. We analyzed the urine of the follicular phase in the morning because of the high correlation to the daily urinary pattern. The distribution of the urinary DHEA excretion in follicular phase of the subjects was in the broad range, 80% distributed in the low levels and 20% in the high level. The scattered diagram of the ratio of DHEA to deoxy17KS was separated to 2 groups. Each of them had a high correlation coefficient. The one group had high DHEA ratio to deoxy17KS, and the other group had a low ratio. These findings suggest that the urinary DHEA excretion pattern is highly specific in each subject and may be used as a measure to see the distinction from the others.

The purpose of the study was to analyse bone density in patients with noninsulin-dependent diabetes mellitus with respect to such factors as the magnitude of obesity, serum cortisol concentration and 17-ketosteroid excretion and insulinemia level. Bone density was measured by ultrasonography, insulin was determined by radioimmunoassay, and steroid level by using the method of Zimmerman. The patients had imminent and overt osteoporosis. The highest serum cortisol concentration was in groups with lower T-score significant negative correlation between cortisol and SOS index. The lowest 17-ketosteroid level was detected in the patients with the lowest T-score; a significant correlation was observed between 17-ketosteroids and BUA index. The present findings indicate an imbalance between bone protective and resorptive factors. This leads to osteopenia in patients with noninsulin-dependent diabetes mellitus despite a protective effect of obesity.

Adrenocortical carcinoma (ACC) is a rare disease with a poor prognosis. It has been difficult to establish a strict treatment program for ACC, and better treatment alternatives and diagnostic tools must be sought. Even though surgery is the treatment of choice, the role of surgery in advanced disease has been questioned. Eighteen consecutive patients were treated at our unit over a 22-year period (1975-1997). All patients underwent surgery and were followed by our protocol, which includes urinary steroid profiles, clinical examinations, analysis of steroid hormones, and radiologic investigations. Twelve patients received mitotane with drug concentration measurements to deliver an effective, nontoxic dose. The median duration of mitotane treatment was 12 months. Few side effects were observed. Four patients with low-stage tumors underwent second-look operations with no pathologic findings. Five patients were subjected to repeat operations, and the mean duration of the disease-free interval before repeat surgery for these patients was 59 months. There was a significant positive correlation between the disease-free interval and the observed survival after repeat surgery. Eleven patients with intentionally curative surgery had their urinary steroid profiles tested several times postoperatively. For five patients preoperative urine samples were also available. Steroid profiles indicated recurrent disease despite normal radiologic findings in two of these five patients. The follow-up ranged from 6 weeks to 24 years. The predicted 5-year survival was 58% according to the Kaplan-Meier method. We conclude that monitoring serum concentrations of mitotane makes long-term treatment possible with few side effects; steroid profile analysis can be used for early detection of tumor recurrence; and repeat surgery for recurrence is of value for patients with long disease-free intervals.

We examined availability of urinary 17-KS-S to evaluate work and job strain by presented the results in two field research and one experiment. It became clear that urinary S/OH was a comprehensive parameter of thermal strain, under the combined load condition of temperature and exercise, and as an additional factor, under the various load conditions of air velocity. Significant changes of urinary S/OH before and after the rest break and holiday suggested that the findings reflected fatigue conditions. This suggestion was strongly supported by the finding that the values of urinary S/OH on the first day-off after a mid-night shift and those 1 to 3 days later were not able to recover to the value before the night shift. A ratio between urinary 17-KS-S and 17-OHCS, S/OH, suggests a method of evaluating the degree of strain and the condition of fatigue and over-fatigue by measuring these parameters and thus clarifying the work conditions and work-place environment.

The aim of this study was to determine whether definite diet changes affect adrenocortical activity and/or adrenal androgen metabolism. A controlled experimental diet study with four consecutive diet periods (repeated measure design) was carried out in six healthy adult volunteers. Four nearly isoenergetic diets, two normal (N) moderately protein-rich, one protein-rich (P), and one low protein lactovegetarian (L), were fed. At the end of each 5-day diet period a blood sample and two 24-h urine specimens were obtained from each subject. Plasma levels of dehydroepiandrosterone sulfate (DHEAS) were elevated with diet L (6.5 +/- 1.4 vs. 5.3 +/- 1.1 mumol/L; P < 0.05) compared to diet N, whereas other plasma hormones, including cortisol and insulin-like growth factor I did not vary markedly. A marked increase of 60% was seen in the urinary 24-h output of 3 alpha-androstanediol glucuronide with diet P. Urinary 24-h excretion rates for C peptide, free cortisol, DHEAS, and total 17-ketosteroid sulfates were clearly reduced with diet L compared to those with diet N or P. Our results show that a lactovegetarian diet can reduce adrenocortical activity (at least after a short term diet change). In addition, this vegetarian nutrition leads to a particular metabolic situation (elevated plasma DHEAS and reduced urinary DHEAS output) that usually is characteristic of fasting. Peripheral androgen metabolism as reflected by urinary 3 alpha-androstanediol glucuronide appears to be influenced only by high protein intake (diet P). Further research (controlled dietary long term investigation) is required 1) to validate whether the effects of diet on adrenocortical activity represent sustained endocrine changes and 2) to elucidate the underlying mechanism.

We attempted to determine compounds in human urine which, differing from 17-OHCS, show high values in healthy individuals, decrease with failing health, clearly decline with advancing disease and finally reach very low values in severe disease. We have initially established that 17-ketosteroid sulfates (17-KS-S) are the compound we were searching for. Hans Selye regarded stress as the rate of wear and tear and 17-OHCS as its indicator, but we considered that, differing from inanimate objects, living organisms consume energy to cope with stress and "repair" "wear and tear" of the tissue "and recover" its function. This concept led us to determine the organism's requirements for two mechanisms: "Wear and tear" which could be represented by the secretion of 17-OHCS (Selye), and "repair and recovery", which could be determined by the amounts of 17-KS-S (Nishikaze) derived from dehydroepiandrosterone sulfate (DHEA-S), a product of the adrenal cortex, which enhances neuronal survival, long-term memory, maintains the function of peripheral tissues (skin, bone-muscle, gastro-intestinal and vascular system etc.), increases lipid metabolism, protein anabolism (antiobesity, antiatherosclerosis etc.) and stimulates the immune system. We hold that the stress response is a series of biological processes, beginning with CRH.ACTH and Catecholamines, Cortisol (17-OHCS), followed by Insulin, acting as an anabolic agent and finally DHEA-S (17-KS-S) induces tissue repair utilizing the energy produced. Low levels of urinary 17-KS-S are observed not only in cases of low cortisol or catecholamines secretion, but also when these are elevated. Normalization of these levels is followed by an increase in 17-KS-S excretion. Balanced changes of hormones, such as 17-KS-S, 17-OHCS, Cortisol, Catecholamines and Insulin are seen in a normal organism under healthy lifestyles and disruption of the balance induces an apparent reduction in 17-KS-S. From this perspective, we hope to research the interrelations between biologically antagonistic 17-KS-S and 17-OHCS as well as other agents, focusing particularly on 17-KS-S, which represents a contact point for mind and body, which is kept in healthy balance by appropriate sleeping and exercise programs along with adequate food intake.

We found an association between low levels of 17-Ketosteroid Sulfates (17-KS-S) in subjects under psychosocial stress. Stress associated with overwork and lack of sleep resulted in decreased levels of 17-KS-S and an increase in 17-Hydroxycorticosteroids (17-OHCS) levels. Alleviation of stress condition was associated with a restoration of the ratio of 17-KS-S/17-OHCS resulting from a slow increase in 17-KS-S and a decrease in 17-OHCS. In subjects with severe mental stress the ratio of 17-KS-S/17-OHCS showed markedly reduced values with a transient marked increase in 17-OHCS. There was a decrease in the levels of 17-KS-S in depressives, which was more pronounced during severe depression. There was no significant difference in 17-OHCS levels. In a cohort experiencing bereavement, there was a reduction in the levels of 17-KS-S, which remained low for about 50 days. With time, the level of 17-KS-S returned to the basal level established prior to spousal death. In this case, there was no significant change in the levels of 17-OHCS. Persistent severe stress over several months in a physician, led to a Herpes Zoster outbreak and Arrhythmia, resulting in hospital admission. The levels of 17-KS-S gradually decreased over this time reaching 1/3 of the normal baseline value, while 17-OHCS levels remained within normal ranges. These results suggest that measurement of 17-KS-S is indispensable for current research on psychosocial stress.

Traditional oriental medicine tells us that everything is interrelated and consists of combinations of opposing factors, "Yin-Yang". So we need to evaluate the normal state and pathologic condition from the perspective of dynamic hormone balance between cortisol and DHEA which are opposing and physiologically very important. Cortisol has a more functional side and is considered Yang, while DHEA has a more material side and is considered Yin. We tried to explain the concepts of KAMPO which include SHO (Yin-Yang. Excess-Deficiency), the 6 Stages of Disease and Deficiency of the Kidney, by measuring urinary 17-OHCS and 17-KS-S, metabolites of cortisol and DHEA. We think our effort may develop a good objective indicator of KAMPO's diagnosis and be useful for selecting of treatment.

In order to evaluate QOL from the perspective of comprehensive medicine, a self-rated QOL Questionnaire and urine 17-KS-S (abbreviated S), 17-OHCS (OH), S/OH were examined in 268 patients (including 11 terminally ill cancer patients) and 31 nurses. Lower S and S/OH were observed in both groups, but OH was higher in patients' group and lower in the nurses' group. Total QOL score was lower in patients' group, but higher in nurses' group. The correlation of each parameter, S, OH and S/OH was related to QOL items. Among terminally ill cancer patients, supplementary treatments were performed. During the course, the elevation of S were observed. In conclusion, S, OH and S/OH were related to QOL and they were considered an objective method of evaluating QOL.

Objective: To study the effects of carbon disulfide on adrenocortical function and analyze and compare the various biological materials used in biological monitoring by observing the changes of adrenocortical hormones and their metabolites in blood, saliva and urine of a viscose rayon mill exposed to carbon disulfide for long-term., Methods: Cortisol in blood and saliva was determined by 125I-radioimmunoassay (RIA), cortisol and cortisone in urine by high performance liquid chromatogaphy (HPLC), and their metabolite 17-ketosteroid by chemical method. Data collected were analyzed by SPSS software in microcomputer to compare their difference between two groups, relationship between them and concentrations of carbon disulfide, and consistence between nontraumatic indices in saliva and urine and blood hormone., Results: Levels of adrenocortical hormones and their metabolites in blood, urine and saliva decreased in the workers exposed to concentrations of carbon disulfide exceeding the national allowable standard, and correlated closely with them. There was a good correlationship between indices in blood and in urine., Conclusion: Blood cortisol, urine free cortisol, cortisone and its metabolite 17-ketosteroid all are good indices for biological effects reflecting adrenocortical function, and detection for urine cortisol and its metabolite is more practicable because of its non-traumatic features.

Using foam rubber 17-ketosteroid (17-KS) and 17-hydroxycorticosteroid (17-OHCS) were separated and collected in urine. 17-KS and 17-OHCS were eluted down from the foam rubber with alcohol, colour reaction can be respectively produced by m-dinitrobenzene and phenyhydrazine hydrocholoride, then both of them were detected by spectro-photometry. The standard deviation of this method was +/- 0.032, and its minimum detectable concentration was 0.01 microgram.ml-1. The recovery rate of 17-KS and 17-OHCS estimation was from 99.0% to 101.0%, with co-efficients of variation less than 6.23%.

The chronic fatigue syndrome (CFS) is a condition of unknown etiology, characterized by a persistent debilitating fatigue, the muscle-related symptoms and the neuropsychiatric symptoms. Recently, it has been reported that the patients with CFS might have impaired activation of the hypothalamic-pituitary-adrenal axis, and suggested that a part of the patho-genesis of CFS might be associated with abnormalities of the endocrine system. Herein, we show that the majority of Japanese patients with CFS had a serum dehydroepiandrosterone sulfate (DHEA-S) deficiency. Serum DHEA-S is one of the most abundantly produced hormones which is secreted from the adrenal glands, and its physiological function is thought to be a precursor of sex steroids. DHEA-S has recently been shown to have physiological properties, such as neurosteroids, which are associated with such psychophysiological phenomena as memory, stress, anxiety, sleep and depression. Therefore, the deficiency of DHEA-S might be related to the neuropsychiatric symptoms in patients with CFS.

The circadian periodicity of urinary 17-ketogenic steroids (17-KGS), 17-ketosteroids (17-KS) and creatinine (Cr) was studied preoperatively and on the 9th postoperative day in 25 histopathologically proved breast cancer patients and in 15 healthy Indian women under tropical conditions. A statistically significant rhythm was observed in healthy participants for all three variables. Urinary corticoids were markedly elevated in breast cancer patients irrespective of the stage of the disease in comparison with healthy controls. The degree of elevation was more pronounced preoperatively in advanced stage breast cancer in comparison with other groups. After mastectomy, the values of all three variables declined markedly, approaching usual values with a circadian rhythm resembling the pattern found in clinical health.

A 53-year-old female had clinical and laboratory findings suggestive of Cushing's syndrome. In contrast to the Cushing's syndrome caused by cortical adenoma, a high level of urinary 17-ketosteroids (17-KS) was also noted. Imaging studies revealed a right adrenal tumor. Right adrenectomy was performed; the surgical specimen revealed a black adenoma consisting of compact cells with numerous pigments which seemed to be lipofuscin in nature. The present case indicates that black adenoma as well as adrenocortical carcinoma should be suspected, when patients with Cushing's syndrome show an increased level of urinary 17-KS excretion.

A series of publications from our laboratory have indicated that the practice of megadose vitamin C drip infusion treatment enhanced the activity of endogenous glucocorticoids in such a way as to improve the clinical course of allergy and autoimmune disease-a disease entity that is known to respond to the therapeutic effect of glucocorticoids. The present paper represents an extention of our vitamin C studies, and intends to investigate the problem whether or not chronic fatigue syndrome (CFS), an acquired immunodeficiency disease, can also be counted as one of the candidate diseases for the vitamin C infusion treatment. We prepared two kinds of vitamin C infusion sets for the clinical use: the dehydroepiandrosterone-annexed vitamin C infusion set (the new set) and the annex-free vitamin C infusion set (the old set). The new set was expected to enhance the endogenous activities of both glucocorticoids and gonadal steroids. We followed the clinical course of a male CFS patient using the old and new vitamin C infusion sets, and with and without the oral intake of erythromycin and chloramphenico. Results obtained are as follows: a) the observation period of a study subject covered a period of August 1995 to May 1996. Combination of pneumonia signs and dermatomyositis signs marked the onset of his CFS. b) Old infusion treatment together with the short term antibiotics treatment was found effective for the control of pneumonia in the first stage of the disease (from August to October, 1995). c) Signs of pneumonia recurrence gradually became eminent in the second stage of disease (from November, 1995, to January, 1996) in spite of the moderate frequency of the old treatment together with stepwise prolongation of the antibiotics treatment. d) The alternate practice of the old and new infusion treatments together with the long-term antibiotics treatment, as conducted in the 3rd stage of disease (from February to May, 1996) led to substantial extinction of pneumonia signs (leucocytosis, tachycardia etc). e) The practice of the new infusion treatment markedly increased the excretion of both 17-ketosteroids and 17-hydroxycorticosteroids in the urine. Evidence was also available to indicate that the dehydroepiandrosterone annex was converted to testosterone, which in turn made a contribution to the control of CFS. f) The immunological survey of lymphocyte subsets including NK cell percent failed to find a coherent change in a study subject with CFS. In conclusion, the above results could be taken as evidence to indicate that the new vitamin C infusion treatment effectuates the clinical control of CFS by fortifying the endogenous activities of both cortisol and testosterone. The significance of parallelism between pulmonary infection and CFS, as observed in the clinical course of the test subject, was discussed in the light of the focal infection theory of nephritis.
