Introduction: Pasireotide normalized or reduced UFC in patients with Cushing’s disease in a large, 12-month study. This analysis evaluates the effects of pasireotide on the signs/symptoms of Cushing’s disease according to the degree of UFC control.Methods: Adult patients (n=162) with persistent/recurrent or de novo Cushing’s disease were randomized to pasireotide 600/900 μg s.c. bid. Dose titration (max: 1200 μg...

Introduction: Generously supported by IPSEN)-->Glucocorticoids (GC) have a stimulatory effect on neutrophils and an inhibitory effect on the other leukocyte subpopulations. A potential stimulatory effect on erythropoiesis has been also hypothesized. The aim of our study was to evaluate the effect of pasireotide treatment on hemochrome parameters in patients with endogenous pituitary-dependent glucocorticoid excess or Cushing’s d...

Background: Novel treatment options are required for patients with adrenocortical carcinomas (ACCs). mTOR-inhibitors are anti-neoplastic drugs that target the mTOR-pathway.Aim: To describe the expression of the mTOR-pathway in normal and pathological adrenocortical tissues.Methods: We evaluated mRNA expression levels of mTOR, S6K and 4EBP1 in 10 normal adrenals (NA), 11 adrenal hyperplasias (AH), 19 adrenal adenomas (ACA) and 26 AC...

Aggressive pituitary tumors are classically defined as pituitary tumors with large size, rapid growth and massive invasion of surrounding anatomical structures. This is a group of pituitary tumors with biological behavior between pituitary adenomas and carcinomas and includes a new group of pituitary tumor, defined atypical adenoma, characterized by the presence of invasive growth and combination of increased mitotic activity and a Ki-67 labeling index >3%. The aim of this...

Introduction: Patients with Cushing’s disease (CD) have an increased risk of hypertension (HTN). phase III data have shown that pasireotide leads to rapid reductions in UFC levels and significant improvements in CD symptoms. We now present further analyses of these data, evaluating the effects of pasireotide on HTN in patients with CD.Methods: Patients with persistent/recurrent or de novo (if not surgical candidates) CD and UFC≥1.5 time...

Introduction: The multi-receptor targeted somatostatin analogue pasireotide has demonstrated efficacy in reducing cortisol in patients with Cushing’s disease in a large, randomized, double-blind, Phase III study. The effects of pasireotide on the signs and symptoms of Cushing’s disease were also investigated as secondary objectives in this trial.Methods: Adult patients with persistent/recurrent or de novo Cushing’s disease were rand...

Aim: To evaluate the effects of short and long-term treatment with PEG on rhythm disturbances in a cohort of acromegalic patients resistant to long-term high-dose therapy with SA.Patients and methods: Thirteen patients (4 M, 9 F, aged 44±9.25 years) entered the study. All patients started PEG at initial dose of 10 mg daily, then increased of 5 mg every 6 weeks on the basis of IGF1 levels, until IGF1 normalisation or until the achievement of the maxi...

Deficiency of 17β-hydroxysteroid dehydrogenase type 3 (17βHSD3), an enzyme converting androstenedione (A) to testosterone (T) in the Leydig cells of the testis, is a rare cause of autosomal recessive 46,XY disorders of sexual development (DSD). A 18-year-old phenotypically female patient presented with primary amenorrhea. She had deep voice, macrocephaly, broad forehead, enlarged nasal tip, macrostomia, facial acne, gynecomastia, left-convex dorsal scoliosis, hypopla...

The GH-receptor antagonist PEG, used as monotherapy or in combination to SA, has been demonstrated to normalize IGF1 levels in up to 90% of acromegalic patients after unsuccessful surgery and/or radiotherapy and resistant to conventional SA treatment. The aim of this study is to evaluate the efficacy and safety of combined treatment with SA plus PEG in a cohort of acromegalic patients resistant to conventional SA therapy. Thirty-two acromegalic patients (17 M, 15 F, age 39.6&#...

Background: Adrenocortical carcinoma (ACC) is an uncommon malignancy with a still scantily understood pathogenesis and generally poor prognosis. Surgery, performed at early stages, offers the best chance for cure, but unfortunately, it is often noncurative. Medical treatment produced disappointing responses. mTOR inhibitors, such as sirolimus (S) and temsirolimus (T), are promising antineoplastic drugs in several types of carcinomas.Methods: To evaluate ...
