Genetic alterations affecting the PKA/cAMP pathway are commonly found in cortisol-producing adrenocortical adenomas (ACAs), while activating mutations in the gene coding for β-catenin (CTNNB1) have been reported in both adenomas and carcinomas. However, the molecular pathogenesis of most ACAs is still unclear. Aim of the study was a comprehensive genetic characterization of sporadic ACAs and the identification of novel molecular markers involved in adrenal tumori...

Recent pan-genomic analyses of tumor DNA identified specific patterns of DNA methylation –e.g. CpG islands hypermethylation in the promoter regions of genes- as pejorative prognostic markers in adrenocortical cancer (ACC). Integrated genomics clearly shows that ACC with such an hypermethylation belongs to specific subgroups of ACC with increased driver genes alterations and a poor survival.Aim: To confirm the prognostic value of this methylation pat...

Hormone replacement therapy with prednisolone is associated with a worse lipid profile than replacement with hydrocortisone in patients with adrenal insufficiency: a matched analysis of data from the EU-AIR

Introduction: Prednisolone is the standard treatment for most inflammatory conditions. However, it is also used in hormone replacement therapy in adrenal insufficiency (AI) for historical reasons or due to its longer half-life and once-daily application. Recent data indicate that daily prednisolone could be associated with lower bone mineral density than daily hydrocortisone in patients with AI. However, data on risk factors for cardiovascular disease in patients with AI treat...

Context: Adrenocortical carcinoma (ACC) is an aggressive malignancy with high recurrence rates. Regular post-operative follow-up imaging is essential, but associated with high radiation exposure and frequent diagnostic ambiguity. Urine steroid metabolomics has been described as a novel diagnostic tool for the detection of adrenocortical malignancy. Here we present the first clinical study assessing the performance of this innovative approach in the follow-up of patients with c...

Is biochemical assessment of pheochromocytoma necessary in adrenal incidentalomas with magnetic resonance features non-suggestive of pheochromocytoma?

Kuzu Idris , Zuhur Sayid Shafi , Ozel Alper , Ozturk Feyza Yener , Altuntas Yuksel

Objective: It is not currently well known whether pheochromocytomas can be ruled out based on low intensity on T2-weighted sequences and signal loss on out-off phase magnetic resonance imaging (MRI) sequences. Hence, in this study we aimed to investigate whether biochemical screening for pheochromocytoma in patients with adrenal incidentalomas (AI) showing MRI features not suggesting pheochromocytoma would prove beneficial.Methods: We performed MRI for 3...
