Effects of mitotane treatment on human steroid metabolism: implications for patient management

L Ghataore, I Chakraborti, S J Aylwin, K-M Schulte, D Dworakowska, P Coskeran, and N F Taylor

in widespread use since publication in 2007 of the large retrospective study of Terzolo et al . (3) . Accumulated knowledge of the mode of action of mitotane together with its effects on steroid synthesis and catabolism is patchy. Mitotane targets

Sex-specific differences in HPA axis activity in VLBW preterm newborns

Britt J van Keulen, Michelle Romijn, Bibian van der Voorn, Marita de Waard, Michaela F Hartmann, Johannes B van Goudoever, Stefan A Wudy, Joost Rotteveel, and Martijn J J Finken

and thawed only once just before analysis. After placement in a salivette, the pad was centrifuged at 1900 g for 5 min, enabling the extraction of urine. Urinary steroids were determined using quantitative data produced by gas chromatography

HIIT produces increases in muscle power and free testosterone in male masters athletes

P Herbert, LD Hayes, NF Sculthorpe, and FM Grace

-frequency HIIT would improve PPO compared with normal exercise training and (ii) systemic steroid hormones would be unchanged following low-frequency HIIT in masters athletes. Materials and methods Participants Following familiarization with

Sexual dimorphism in cortisol metabolism throughout pubertal development: a longitudinal study

Britt J van Keulen, Conor V Dolan, Bibian van der Voorn, Ruth Andrew, Brian R Walker, Hilleke Hulshoff Pol, Dorret I Boomsma, Joost Rotteveel, and Martijn J J Finken

cortisol levels. Compared to girls, boys, up to age 8, had higher salivary cortisol levels and lower levels beyond this age ( 11 ). The timing of this change suggests that sex steroids influence the HPA axis. Surprisingly, to the best of our knowledge

Steroid metabolomic signature of liver disease in nonsyndromic childhood obesity

Aneta Gawlik, Michael Shmoish, Michaela F Hartmann, Stefan A Wudy, Zbigniew Olczak, Katarzyna Gruszczynska, and Ze’ev Hochberg

there is possibility of multiple diagnoses or before starting therapy with potentially hepatotoxic medications’ ( 8 ). The consequences of obesity-related NAFLD on liver metabolism are insufficiently understood ( 8 ). As steroid hormones are partially

Higher steroid sulfation is linked to successful weight loss in obese children

Thomas Reinehr, Alberto Sánchez-Guijo, Nina Lass, and Stefan A Wudy

Introduction Obesity is a complex condition associated with changes in many steroid hormones also including androgens: concentrations of testosterone and DHEAS and their precursors are increased in children ( 1 , 2 ) and obese women ( 3

Exercise training improves free testosterone in lifelong sedentary aging men

Lawrence D Hayes, Peter Herbert, Nicholas F Sculthorpe, and Fergal M Grace

Introduction Testosterone is a sex steroid hormone with profound influence on various tissues ( 1 , 2 , 3 ). The precipitous decline in systemic testosterone with age is well described ( 4 ). Additionally, sex hormone-binding globulin (SHBG

Anabolic androgenic steroid abuse in young males

Willem de Ronde and Diederik L Smit

Introduction Every now and then a clinical endocrinologist will be visited by a patient that uses anabolic androgenic steroids (AAS) or has been using them in the past. The interaction between doctor and patient may be hampered for a number of

Diurnal variation of steroid hormones and their reference intervals using mass spectrometric analysis

T P Parikh, B Stolze, Y Ozarda, J Jonklaas, K Welsh, L Masika, M Hill, A DeCherney, and S J Soldin

Introduction Diurnal variations in the serum concentration of steroid hormones and their metabolism, as assessed by urinary excretion, have long been known for cortisol and testosterone ( 1 , 2 , 3 ). Less information exists for the other up

Assay of steroids by liquid chromatography–tandem mass spectrometry in monitoring 21-hydroxylase deficiency

Sandra R Dahl, Ingrid Nermoen, Ingeborg Brønstad, Eystein S Husebye, Kristian Løvås, and Per M Thorsby

assessment is not sensitive enough to identify subtle over- and under-treatment. Assay of the intermediates 17-hydroxyprogesterone (17OHP) and androstenedione is often used, but results are often difficult to interpret as cross-reactivity between steroids
