Dysregulation of the enzymes that control local tissue steroid metabolism has been implicated in the pathogenesis of obesity and insulin resistant states, however longitudinal changes in glucocorticoid metabolism over time have not been investigated. This study was designed to evaluate the role of pre-receptor glucocorticoid metabolism in the development of insulin resistance and obesity. 24 h urinary glucocorticoid and mineralocorticoid metabolites were measured by gas chroma...

Polycystic ovary syndrome (PCOS) is a clinical triad of anovulation, insulin resistance, and androgen excess. Hyperandrogenism may correlate with metabolic risk but PCOS consensus criteria currently define androgen excess on the basis of serum testosterone only. Here we studied the utility of the androgen precursor serum androstenedione in conjunction with serum testosterone as a predictor of metabolic dysfunction in PCOS.86 PCOS patients fulfilling Rott...

Introduction: Generously supported by IPSEN)-->Measurement of salivary cortisol is a simple, convenient, accurate and reproducible technique with potential value during the diagnosis/management of hypercortisolism. Current analysis evaluates changes in late-night salivary cortisol (LNSC) during pasireotide treatment in patients with Cushing’s disease (CD).Methods: A 12 m, Phase III study enrolled 162 adult...

In the pathogenesis of obesity, dysregulated tissue cortisol metabolism (controlled by 11β-HSD1), is postulated to be involved. Fifteen patients (seven mens, mean BMI 50.8±7 kg/m2) awaiting Roux En Y gastric Bypass (RYGB) surgery underwent assessment of 11β-HSD1 activity using cortisol generation profile. Corticosteroids in serum and subcutaneous adipose tissue microdialysis fluid and urinary corticosteroid metabolites were analysed by liquid and gas ...

Mitotane (o,p’DDD) is the first-line treatment for metastatic adrenocortical carcinoma (ACC) and is also regularly used in the adjuvant setting after presumed complete removal of the primary tumour. Mitotane is considered an adrenolytic substance, but no information is available regarding distinct steroidogenic effects. Here we carried out steroid metabolomics by gas chromatography/mass spectrometry in 24-hour urine samples from 106 patients with ACC and with samples coll...

Adrenal tumors have an incidence of 2–3% in the general population and the work-up of incidentally discovered adrenal masses represents a major burden to the health system. Differentiating adrenocortical adenoma (ACA) from adrenocortical carcinoma (ACC) represents a continuous challenge, with unfavorable sensitivities and specificities provided by tumor size, imaging and even histology. Here, we aimed to develop a reliable screening tool for the detection of adrenal malig...

Objective: Our study evaluates the contribution of untreated GHD to the phenotype in controlled CD, by comparing patients with GHD due to CD (n=322) and those with non-functioning pituitary adenoma (NFPA n=748) before and after 3 years of GH treatment.Methods: The patient cohorts were obtained from KIMS (Pfizer International Metabolic Database) and matched for age and gender. Duration between pituitary disease onset and GH start was 9.7 (CD...

Two medical therapies are now available for the treatment of acromegaly. Pegvisomant is a growth hormone (GH) receptor antagonist. Somatostatin analogues, in contrast, act by inhibiting the release of GH from the pituitary. The primary objective of this study was to compare the efficacy of pegvisomant (P) to that of octreotide LAR (LAR) in terms of IGF-1 normalisation. The secondary objective was to compare safety and tolerability between the two treatments.<p class="abste...

Background: Non-alcoholic fatty liver disease (NAFLD) is recognized as common liver disorder that represents the hepatic manifestation of the metabolic syndrome including visceral obesity, type 2 diabetes, insulin resistance and hyperlipidemia. Non-alcoholic steatohepatitis (NASH) is the progressive form of liver injury with the risk for progressive fibrosis, cirrhosis and end-stage liver disease. The pathophysiology that leads to NAFLD and NASH is not well understood. We hypo...

IntroductionThe oral 11β-hydroxylase inhibitor, osilodrostat, normalized mean urinary free cortisol (mUFC) in 79% (15/19) of patients with Cushing’s disease at the end of the 22-week core LINC 2 study. Long-term efficacy and safety data following an optional extension phase are reported here.MethodsPatients with clinical benefit at week 22 could continue receiving osilodrostat during the extension; ...
