Aim: We compared effectiveness of partial withdrawal of levothyroxine (L-T4) to the use of recombinant human TSH (rhTSH) in preparation for Tg testing. We also evaluated clinical aspects and quality-of-life (QOL) during both regimens.Materials and methods: Ten consecutive patients, previously treated with total thyroidectomy and radioiodine ablation for DTC, underwent rhTSH protocol and, after 15 days, reduced their L-T4 dose by 50% for 5 weeks. At the f...

Long noncoding RNAs (LncRNAs) are transcripts of more than 200 nucleotides not translated into proteins. They carry out diverse functions, including transcriptional regulation in cis or trans, organization of nuclear domains, and regulation of proteins or RNA molecules. Aberrant expression of LncRNAs has been reported in human cancers; indeed, data in parathyroid tumors are lacking. Based on the profiling through lncProfilersTM qPCR Array with SYBR...

Endometriosis is a chronic gynecological inflammatory disease characterized by the presence of functional endometrial glands and stroma outside of the uterine cavity. It affects 7–10% of women of reproductive age, up to 50% of women with infertility and up to 60% of women with dysmenorrhea. The aim of this pre-clinical study was evaluate the efficacy of low-dose SKA Progesterone (GUNA) and low-dose SKA IL-10 (GUNA) in the modulation of the inflammatory response in endomet...

Introduction: A significant number of GH-secreting pituitary adenomas show an aggressive behavior, therefore, when uncontrolled acromegaly persists, a pharmaceutical combination may improve biochemical control, with reduction of disease morbidity and mortality. We aimed to describe the clinical features of four patients successfully treated with a pharmacological combination of pasireotide LAR, pegvisomant and cabergoline.Case reports: Acromegaly was dia...

Purpose: Primary hypophysitis is a rare disease, with an autoimmune etiology. As few papers have investigated its genetic, our aim was to evaluate HLA status in a single-center series of patients.Patients and method: A retrospective, longitudinal and cross-sectional study was conducted. Consecutive Caucasian patients, with clinical or histological diagnosis of primary autoimmune hypophysitis (PAH), undergone determination of HLA genotype, anti-pituitary ...

Introduction: Pasireotide Lar is a new generation long-acting somatostatin multireceptor ligand, approved for the treatment of first line somatostatin analogue resistant patients. We aimed to review Pasireotide Lar efficacy data, in our series of patients affected by aggressive acromegaly.Patients: A retrospective longitudinal study was conducted on patients with aggressive acromegaly, resistant to first-line somatostatin analogues (SSA) and on treatment...

Background: Tyrosine kinase inhibitors (TKIs) are modern antineoplastic molecules widely used in the medical treatment of many cancers including iodine refractory differentiated thyroid carcer (DTC) and advanced medullary thyroid cancer (MTC). In patients with thyroid gland, TKIs frequently cause a destructive and/or autoimmune thyroiditis with consequent hypothyroidism. However, authors have reported unexpected TSH increase or hypothyroidism even in patients with total thyroi...

Background: Adrenocortical carcinoma (ACC) is a rare cancer for which available systemic treatments, mitotane ± etoposide, doxorubicin and cisplatin (EDP-M), have limited efficacy.Objectives: Here, we strengthen the effect of progesterone (Pg) on metastatic ACC cell lines, studying whether it could influence growth, invasiveness, and metastasis formation. Additionally, we investigate if the Pg analogue megestrol-acetate administered with EDP-M could...

Background: Acromegaly is associated with skeletal fragility and increased prevalence of vertebral fractures (VF). In recent years several authors tried to investigate predictor markers of bone fragility risk in this endocrine disorder. Two isoforms of GH receptor (GHR) have been described, which differ in the presence or absence of a transcript of exon 3 of the GHR gene. Both isoforms produce a functional receptor, but the exon 3-deleted isoforms (d3-GHR) have greater sensiti...

Background: We sought to document the pattern of distribution of cytokines in patients with type 2 DM and compare cytokine levels between DM subjects with and without the Mets.Methods: Out of 200 patients with type 2 DM and 100 healthy sex and aged matched controls were studied. Anthropometric indices, lipid parameters and cytokines levels which included interleukin 10 (IL10), tumor necrosis factor α (TNF), interferon γ (IFN) and C reactive pro...
