A recent phase III clinical trial has demonstrated that the treatment with the somatostatin analogue pasireotide normalizes cortisol secretion in 15–28% of patients with Cushing’s disease (CD). The aim of the current study was to evaluate the effectiveness of 6-months pasireotide treatment on clinical and hormonal profiles in a group of CD patients with mild to moderate disease according with the real-word evidence. Thirty-two patients with CD unsuccessfully treated ...

Introduction: The PAOLA study in patients with inadequately-controlled acromegaly (n=198) demonstrated superior efficacy of pasireotide long-acting release (LAR; 40 mg/60 mg) in biochemical control (GH <2.5 μg/l and normalized IGF-1) vs continued treatment with octreotide LAR 30 mg/lanreotide Autogel 120 mg (15.4% and 20.0% vs 0%). Here we report preliminary data from the extension phase of PAOLA at wk28.Methods: Pasireotide-LAR (40 mg/...

The mTOR and IGF pathways have been suggested to play a role in the pathogenesis of pheochromocytomas (PCC). mTOR inhibitors, as sirolimus (S) and everolimus (E), as well as IGF1R antagonists could be a potential novel treatment for malignant PPC.The aim of this study was to evaluate the expression of the main components of the IGF/mTOR pathway in human PCC and to investigate the effects of the mTOR inhibitors S and E and of the IGF1R/insulin receptor (I...

Context: Primary hyperparathyroidism (PHPT) is a common endocrine disease, characterized by the chronic elevation of serum calcium (Ca) levels induced by a long-standing increase of PTH concentrations. PHPT includes mild-asymptomatic and symptomatic forms. Cinacalcet is effective in lowering serum Ca levels in PHPT, but is indicated solely in mild-asymptomatic PHPT meeting surgery criteria. Management of non-surgical mild-asymptomatic PHPT is still a debated issue.<p class...

Background: Some patients with acromegaly do not achieve biochemical control despite receiving maximum-approved doses of currently available somatostatin analogues. This 24-week, randomized study assessed the multireceptor-targeted somatostatin analogue pasireotide LAR vs octreotide LAR/lanreotide Autogel in patients with inadequately controlled acromegaly.Methods: Eligible patients: ≥18 years with mean GH levels ≥2.5 μg/l and IGF1 level...

Background: The human cytochrome P450 (CYP) 2W1 is involved in the metabolism of several endogenous substrates, including lysophospholipids and fatty acids. Using a polyclonal antibody, we previously demonstrated a high CYP2W1 immunoreactivity in adrenocortical tumors, particularly in those secreting steroids. The aim of the study was to better elucidate the relationship between CYP2W1 and steroid secretion in adrenocortical carcinoma (ACC) H295R cell line and in a larger seri...

Cancer exosomes emerged as important mediators of cancer drug resistance. Drug exposure-mediated EveR in HCC cell lines can be reversed by VitD pre- and co-treatment. The current study aimed to investigate whether cancer exosomes from EveR HCC cell line are able to induce EveR in parental cells and whether VitD may activate reversal effect on exosome-mediated EveR.To this purpose, parental JHH-6 and EveR JHH-6 cell line were used. The uptakeof exosomes, ...

Pasireotide (PAS) has a safety profile similar to first-generationsomatostatin analogues (SSA), except for a higher frequency of hyperglycaemia-related adverse events (AEs). However, consensus on the best management of PAS-induced hyperglycaemia in acromegalic patients has still to be defined. The current study aims at investigating the effects of long-term PAS treatment on glucose metabolism, by evaluating the clinical management of hyperglycemia-relatedAEs in acromegalic pat...

The Liège Acromegaly Survey is a cross-sectional study on acromegalic patients, developed as an in-house tool in Liège, then extended to other Europeans participating centers. The database differentiates itself from national and multinational registries by adopting a goal oriented approach and it was conceived following a list of open questions on acromegaly. After an initial test run in Liège, the database installation started on mid-March 2010. Thirteen other ...

Introduction: Natural history of lung neuroendocrine tumours (NETs) and in particular of two histological subtypes, atypical carcinoid (AC) and large cell neuroendocrine carcinoma (LCNEC), is poorly known.Aim of the study was to determine disease-free survival (DFS) and overall survival (OS) of sporadic, resectable, non-metastatic lung AC and LNEC.Patients and methods: This retrospective study involved 116 consecutive patients surg...
