To determine a correlation between Vitamin D, GH, IGF1 and cardiovascular risk we enrolled. 41 GHD patients (22 M, 19 F, age 18–84 years) and 41 controls. In all we determined: anthropometric parameters, blood pressure (BP), lipid and glucose profile, PTH, 25-OH-vitamin D, GH peak after GHRH+ARG, IGF1. Metabolic syndrome (MS) was evaluated by the IDF criteria.The vitamin D were lower in patients than in controls (21.3±12.3 vs 28.2±9.4, <em...

GH replacement is widely used in adults with hypopituitarism, but its effect on tumor occurrence and pituitary tumor recurrence is unknown. Furthermore, in literature there are scant with short follow-up time. The available data do not seem to suggest that rhGH replacement increased the incidence of regrowth of pituitary tumor and of cancer in adults with GHD, provided that IGF1 concentrations remain within the normal range for age.The aim of our study w...

Objectives: Brain Derived Neurotrophic Factor (BDNF) plays a fundamental role in regulation of metabolism and energy homeostasis. Low BDNF levels have been identified as possible biological causes for development of obesity and BDNF administration has been shown to induce weight loss and to improve insulin sensitivity in diabetic animal models. Acute exercise is known to induce a transient increase of peripheral BDNF but no information is yet available regarding the exercise-i...

Background: Deciding whether patients with a cytologically indeterminate thyroid nodule should be referred for surgery or for active surveillance is an important challenge for clinicians. The aim of this study was to evaluate the performance of a novel dual-component molecular assay as an ancillary molecular method for resolving indeterminate thyroid nodule cytology.Methods: We selected 156 thyroid nodules from those that had undergone both FNA cytology ...

Background: Craniopharyngiomas are benign tumors of the parasellar and sellar region. Patients with craniopharyngioma, treated with surgery, have comorbidities such as obesity and multiple pituitary deficiencies.Aim: To evaluate the metabolic parameters of patients with craniopharyngioma treated with surgery.Methods: We recruited 20 patients with craniopharyngioma (M=11, 46.6±12.6) and 20 patients (M=10, 53.5&#17...

Introduction: Italy is considered a country with high prevalence of 25 OH vitamin D deficiency. Changes in vitamin D serum levels were linked with the onset and progression of several diseases, including osteoporosis and cardiovascular diseases. The hypopituitary patients show several comorbidities like cardiovascular diseases and osteoporosis.Purpose: To evaluate the prevalence of vitamin D deficiency in hypopituitary patients.Pat...

Patients with hyperprolactinemia have impaired bone metabolism and bone mineral density (BMD) partially represents bone’s health.To evaluate vitamin D levels, PTH, Ca and P, BMD and bone morphometry in patients with prolactin-secreting pituitary adenomas.Forty-four patients (30 W, 40±11 years, BMI 27.6±5 kg/m2) underwent to lumbar and femoral DEXA, to vertebral morphometry by X-ray and was calculated the S...

Radioiodide 131I (RAI) is the therapy of choice for radioiodine-avid differentiated thyroid cancer (DTC). However, 5–15% of DTC patients become RAI refractory (RAIR), and the 10-year survival rate for metastatic disease decreases to 10%. The failure of RAI response is mainly due to the loss of thyroid differentiation, that leads to the loss of expression/function of components of iodide metabolism, first of all the Na/I symporter (NIS). The finding that the MAPK pathway i...
