Glucocorticoid receptor polymorphisms and post-traumatic stress disorderAnthony W Bachmann

Psychoneuroendocrinology 30:297-306. 2005..Our PTSD group did not display GC hypersensitivity, as measured by the LD-DST and DVVA.

Horm Metab Res 39:439-44. 2007..Studies directed at determining if free cortisol is a better guide than total cortisol to the need for hydrocortisone supplementation may be of value... - Corticosteroid-binding globulin gene polymorphisms: clinical implications and links to idiopathic chronic fatigue disordersD J Torpy
Endocrine and Metabolic Unit, and the Hanson Institute, Royal Adelaide Hospital, Adelaide, South Australia, Australia
Clin Endocrinol (Oxf) 67:161-7. 2007..A mechanism for the effect of CBG mutations on fatigue is not readily apparent because free cortisol levels are normal, although we speculate that CBG may have an effect on cortisol-brain transport... - Association between chronic fatigue syndrome and the corticosteroid-binding globulin gene ALA SER224 polymorphismDavid J Torpy
University of Queensland Department of Medicine, Greenslopes Hospital, Brisbane, Queensland, Australia
Endocr Res 30:417-29. 2004..Homozygosity for the serine allele of the CBG gene may predispose to CFS, perhaps due to an effect on hypothalamic-pituitary-adrenal axis function related to altered CBG-cortisol transport function or immune-cortisol interactions... - Early rise in blood pressure following administration of adrenocorticotropic hormone-[1-24] in humansR V Jackson
Neuroendocrine Research Unit, Department of Medicine, University of Queensland, Greenslopes Private Hospital, Brisbane, Queensland 4120, Australia
Clin Exp Pharmacol Physiol 28:773-5. 2001..5. The cardiovascular consequences of therapeutic use of ACTH are well recognized. This results of the present study suggest that even diagnostic administration of ACTH, delivered over a few hours, may raise blood pressure... - The insulin hypoglycemia test: hypoglycemic criteria and reproducibilityE J Nye
Neuroendocrine Research Unit, Department of Medicine, Brisbane, The University of Queensland, Queensland, Australia
J Neuroendocrinol 13:524-30. 2001..Overall, the cortisol response to hypoglycemia is more reproducible than the ACTH response but, in an individual subject, the difference in peak cortisol between two IHTs may exceed 100 nmol/l... - Familial corticosteroid-binding globulin deficiency due to a novel null mutation: association with fatigue and relative hypotensionD J Torpy
Department of Medicine, University of Queensland, Greenslopes Private Hospital, Brisbane, Queensland 4120, Australia
J Clin Endocrinol Metab 86:3692-700. 2001..As idiopathic fatigue disorders are associated with relatively low plasma cortisol, abnormalities of corticosteroid-binding globulin may be pathogenic... - Characteristics of plasma NOx levels in severe sepsis: high interindividual variability and correlation with illness severity, but lack of correlation with cortisol levelsJ T Ho
Hanson Institute, Endocrine and Metabolic Unit, Royal Adelaide Hospital, Adelaide, Australia
Clin Endocrinol (Oxf) 73:413-20. 2010..NOx levels were not suppressed reproducibly by hydrocortisone. High interindividual variability of NOx levels suggests that absolute NOx levels may not be a suitable target for individualized hydrocortisone therapy... - Moderate weight loss reduces renin and aldosterone but does not influence basal or stimulated pituitary-adrenal axis functionJ T Ho
Royal Adelaide Hospital, Adelaide, South Australia, Australia
Horm Metab Res 39:694-9. 2007..There may be a threshold effect of weight loss/energy restriction required to alter HPA axis function, or moderate weight loss may lead to a counterbalanced effect of stimulatory and inhibitory influences on HPA axis function... - Septic shock and sepsis: a comparison of total and free plasma cortisol levelsJ T Ho
Hanson Institute, The University of Adelaide, Adelaide, Australia
J Clin Endocrinol Metab 91:105-14. 2006.... - CBG Santiago: a novel CBG mutationD J Torpy
Endocrine and Metabolic Unit, Royal Adelaide Hospital, North Terrace, Adelaide 5000, South Australia, Australia
J Clin Endocrinol Metab 97:E151-5. 2012..Corticosteroid-binding globulin (CBG; SERPIN A6) gene mutations are rare; only four mutations have been described, often in association with fatigue and chronic pain, albeit with incomplete penetrance... - Adrenocorticotropin stimulation tests in patients with hypothalamic-pituitary disease: low dose, standard high dose and 8-h infusion testsE J Nye
Department of Medicine, The University of Queensland, Brisbane, Australia
Clin Endocrinol (Oxf) 55:625-33. 2001..1 microg) or a high dose prolonged infusion does not greatly improve the sensitivity of ACTH [1-24] testing. Dynamic tests that provide a central stimulus remain preferable in the assessment of patients with suspected ACTH deficiency... - Corticosteroid-binding globulin: the clinical significance of altered levels and heritable mutationsLucia Gagliardi
School of Medicine, University of Adelaide, Adelaide, SA 5005, Australia
Mol Cell Endocrinol 316:24-34. 2010..Further studies may clarify the functions of CBG, and clinical observations may validate and/or extend the phenotypic features of various CBG mutations... - Familial vasopressin-sensitive ACTH-independent macronodular adrenal hyperplasia (VPs-AIMAH): clinical studies of three kindredsLucia Gagliardi
Endocrine and Metabolic Unit, Royal Adelaide Hospital, Adelaide, South Australia 5000, Australia

School of Medicine, University of Adelaide, Adelaide, South Australia, Australia
Horm Metab Res 42:280-4. 2010..The NSC and DST should be compared directly in metabolic disorder patients; although our data suggest the patient group will need to be substantially larger to definitively determine the optimal screening test... - Association of hypertension and hypokalemia with Cushing's syndrome caused by ectopic ACTH secretion: a series of 58 casesDavid J Torpy
