Alteration in glucocorticoids secretion and metabolism in patients affected by cystic fibrosis.
Podgórski R, Sumińska M, Rachel M, Fichna M, Fichna P, Mazur A. Podgórski R, et al. Front Endocrinol (Lausanne). 2022 Dec 8;13:1074209. doi: 10.3389/fendo.2022.1074209. eCollection 2022. Front Endocrinol (Lausanne). 2022. PMID: 36568105 Free PMC article.
Furthermore, the activity of 5alpha-reductase seems to be enhanced only through the backdoor pathway, especially when we taking into consideration 11beta-hydroxyandrosterone/11beta-hydroxyetiocholanolone ratio which has been shown to be the best differential marker …

Development of criteria for the detection of adrenosterone administration by gas chromatography-mass spectrometry and gas chromatography-combustion-isotope ratio mass spectrometry for doping control.
Brooker L, Parr MK, Cawley A, Flenker U, Howe C, Kazlauskas R, Schänzer W, George A. Brooker L, et al. Drug Test Anal. 2009 Nov;1(11-12):587-95. doi: 10.1002/dta.108. Drug Test Anal. 2009. PMID: 20355175
The urinary metabolism of adrenosterone was investigated, after a single oral administration in two male subjects, by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). Substantially increased excretion of …

Two-step biochemical differential diagnosis of classic 21-hydroxylase deficiency and cytochrome P450 oxidoreductase deficiency in Japanese infants by GC-MS measurement of urinary pregnanetriolone/ tetrahydroxycortisone ratio and 11beta-hydroxyandrosterone.
Koyama Y, Homma K, Fukami M, Miwa M, Ikeda K, Ogata T, Hasegawa T, Murata M. Koyama Y, et al. Clin Chem. 2012 Apr;58(4):741-7. doi: 10.1373/clinchem.2011.173286. Epub 2012 Jan 24. Clin Chem. 2012. PMID: 22273564
RESULTS: At a cutoff of 0.020, the ratio of Ptl to THEs differentiated C21OHD and PORD from TH17OHP and controls with no overlap. Among metabolites of DHEA, AD4, and 11OHAD4, only 11beta-hydroxyandrosterone (11HA), a metabolite of 11OHAD4, showed no overlap between …

Maternal urine and serum steroid measurements to identify steroid sulfatase deficiency (STSD) in second trimester pregnancies.
Marcos J, Craig WY, Palomaki GE, Kloza EM, Haddow JE, Roberson M, Bradley LA, Shackleton CH. Marcos J, et al. Prenat Diagn. 2009 Aug;29(8):771-80. doi: 10.1002/pd.2284. Prenat Diagn. 2009. PMID: 19418464
METHODS: We studied detection rate and false positive rate (DR, FPR) of analytes in maternal urine [combinations of 16alpha-OH-dehydroepiandrosterone sulfate (16alpha-OH-DHEAS), 11beta-hydroxyandrosterone, total estriol] and serum [combinations of 16alpha-OH-DHEAS, …

Circulating adrenal 11-oxygenated androgens are associated with clinical outcome in endometrial cancer.
Dahmani C, Caron P, Simonyan D, Turcotte V, Grégoire J, Plante M, Guillemette C. Dahmani C, et al. Front Endocrinol (Lausanne). 2023 May 23;14:1156680. doi: 10.3389/fendo.2023.1156680. eCollection 2023. Front Endocrinol (Lausanne). 2023. PMID: 37288302 Free PMC article.
Higher levels of preoperative free 11-ketoandrosterone (11KAST) were associated with an increased risk of recurrence (Hazard ratio (HR) of 2.99 (95%CI=1.09-8.18); P=0.03). Postoperative free 11beta-hydroxyandrosterone (11OHAST) levels were adversely associated with …

17-Hydroxylase/C17,20-lyase (CYP17) is not the enzyme responsible for side-chain cleavage of cortisol and its metabolites.
Shackleton CH, Neres MS, Hughes BA, Stewart PM, Kater CE. Shackleton CH, et al. Steroids. 2008 Jul;73(6):652-6. doi: 10.1016/j.steroids.2008.02.001. Epub 2008 Feb 13. Steroids. 2008. PMID: 18355883
The question addressed in this study was the nature of the enzyme required to remove the side-chain of 17-hydroxycorticosteroids, leading in the case of cortisol to the excretion of 11beta-hydroxyandrosterone, 11-oxo-androsterone and the corresponding etiocholanolon …

13C/12C ratios of endogenous urinary steroids investigated for doping control purposes.
Piper T, Flenker U, Mareck U, Schänzer W. Piper T, et al. Drug Test Anal. 2009 Feb;1(2):65-72. doi: 10.1002/dta.15. Drug Test Anal. 2009. PMID: 20355178
The (13)C/(12)C ratio of a target substance (androsterone, a testosterone metabolite) was compared to the (13)C/(12)C ratio of an endogenous reference compound (11beta-hydroxyandrosterone).N = 1340 samples were investigated due to elevated testosterone/epitestostero …

When considering each hormone metabolite individually, we found positive associations between early pregnancy PM(2.5) exposure and five steroids, two of which survived multiple comparison testing: 11beta-hydroxyandrosterone glucuronide (a pregnenolone steroid) and a …
