Psychoneuroendocrinology 30:297-306. 2005..Our PTSD group did not display GC hypersensitivity, as measured by the LD-DST and DVVA. In a subset of PTSD patients with the BclI GG genotype, CAPS scores and basal cortisol levels were negatively correlated...

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...

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...

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...

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...

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...
