Objective: Several studies including ours have reported significant associations between polymorphisms (SNPs) of the HSD11B1 gene and bone metabolism. The aim of the present study was to explore systematically the potential associations between SNPs of the HSD11B1 gene and bone mineral density (BMD) in women with endogenous Cushing’s syndrome (CS) and healthy postmenopausal women.Patients and methods: A complex bioinformatical including haplotype an...

Background: Midnight salivary cortisol (SalC2400) measurement has been recently suggested as one of the first-line screening tests for hypercortisolism.Aims: In our present study, we evaluated the clinical utility of the salivary cortisol (SalC) measurement in the diagnosis of both overt and subclinical Cushing’s syndrome.Patients and methods: Patients with overt Cushing’s syndrome (n=23, group A) and those with su...

Introduction: The hypothalamic–pituitary–adrenal axis setpoint and the glucocorticoid sensitivity in various tissues are at least partly genetically determined. The glucocorticoid receptor (GR) gene polymorphisms may have an impact on the development and/or the variability of clinical manifestations of endogenous hypercortisolism, however their role has not been investigated in patients with endogenous hypercortisolism.Methods: We investigated ...

Introduction: Altered sensitivity against glucocorticoids is partly influenced by polymorphisms (SNP) of the glucocorticoid receptor gene (GR). The aim of the present study was to extend our earlier study by inclusion and evaluation the role of the BclI and A3669G polymorphisms of the GR in patients with hormonally inactive adrenal adenomas.Description of methods: This is a retrospective, single-centre genetic association study The study included 99 pati...

Objective: Genetic variation in the glucocorticoid receptor (GR) gene may be related to the clinical heterogenety and severity of the Cushing’s syndrome. BclI, N363S and ER22/23EK polymorphisms are the three most investigated polymorphisms within the GR gene, however, the importance and magnitude of their effect in hypercortisolemic states are unclear. The BclI and the N363S variants are associated with increased, while the ER22/23EK variant is associated with reduced glu...

Introduction: The most important feature of bone metabolism in patients with Cushing’s syndrome is the uncoupling of osteoblast and osteoclast activity resulting in suppressed bone formation.Objective: The aim of the present study was to investigate the altered bone turnover in patients with various forms of Cushing’s syndrome in the active phase of the disease as well as after successful normalization of cortisol overproduction.<p class="a...
