Background: Although the role of hypermethylation of certain tumor suppressor genes are known in pituitary adenomas little information is available regarding whole methylation-demethylation status and especially regarding its correlation with clinical parameters. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) is an easy and accurate method to detect the level of methylcytosine (5 mC) and the demethylation intermedier hydroxymethylcytosine (5 hmC) ...

Background: Congenital adrenal hyperplasia (CAH) is an autosomal recessive inherited disorder caused by 21-hydroxylase deficiency in 95% of all cases. Two main clinical subtypes: the classical (manifested after birth, or in early newborn period) and the late onset (LO) phenotype (manifested commonly during puberty). The lifelong glucocorticoid (GC) supplementation is essential in therapy of these patients. Response to GC therapy is individual and partly genetically determined....

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...
