Introduction: The management of patients with adrenal incidentaloma (AI) and possible subclinical hypercortisolism (SH) is debated. This randomized study was aimed to evaluate the effects of adrenalectomy on arterial hypertension (AH).Methods: We consecutively evaluated 590 AI patients (referred to 3 Italian Centres between 06/2016 and 12/2019). Among these, 134 patients showed a possible SH (i.e. 1 mg DST between 1.8 and 5 µg/dl). Based on the excl...

Metabolism of glucose in patients with acromegaly treated with Pegvisomant and/or Pasireotide LAR after resistance to first generation somatostatin receptor ligands

Introduction: Acromegaly (Acro) is characterized by insulin sensitivityreduction, glucose intolerance (IGT) and diabetes mellitus (DM2 in 15%–38% of patients). Studies that investigated action of medical therapies for acro on glucose metabolism, didn’t provide conclusive data. Association between blood glucose (BG) levels and serum IGF-I levels in patients with DM2 and acro has been suggested, however,IGF-I levels and hemoglobin A1c (HbA1c) correlation is still con...

Objective: Oxidative stress has been implicated in the pathogenesis of several immune-mediated disorders, including autoimmune thyroid disease. Aim of our study was to investigate the relationship between dietary habit and redox homeostasis, in relationship with thyroid autoimmunity.Materials and methods: We enrolled 200 healthy subjects (173 F, mean age 35 ± 12). None of them was under any pharmacological treatment. Exclusion criteria: any infectio...

Hyaluronan in part mediates IL-1beta-induced inflammation in human thyrocytes by up-regulating TLR-4 and CD44 receptors

Ruggeri Rosaria , Teresa Vicchio Maria , Campennì Alfredo , Campo Salvatore , Trimarchi Francesco , Cannavo’ Salvatore , D’Ascola Angela

Background: The expression of thyroid-specific genes [thyroglobulin (Tg) and sodium iodide symporter (NIS)] is modulated by several cytokines (IL-1, IFNγ, TGF-ß) and it is down-regulated in Hashimoto’s thyroiditis (HT). Also, lymphocytic infiltration and inflammation in HT results in intra-thyroidal accumulation of hyaluronan (HA). During inflammation, HA can be degraded into small fragments, able to up-regulate pro-inflammatory genes by stimulating the toll-li...

Ectopic parathyroid hormone secretion by a squamous cell carcinoma of the floor of the mouth with poor response to cinacalcet

Bilbao Ismene , Egaña Nerea , Rojo Jorge , Garcia Cristina , Olaizola Izaskun , Agea Leire , Aranburu Maite , Yoldi Alfredo , Goena Miguel

Introduction: Ectopic PTH secretion is rare, to our knowledge, with only 27 cases reported in the literature and 3, ( a tonsil, a lung and a penile) due to squamous cell carcinoma .In the few cases reported to date it appears to be more common in males and in those over the age of 60. The management of the hypercalcemia in this setting is complicated. We are aware of 2 other case reports in which cinacalcet was used in this context, but as in our case, unsuccessfully.<p cl...

Immunoassay interference on thyroid functions tests during treatment with Nivolumab

Background: Immune checkpoint inhibitors (ICI), anticancer therapy blocking specific molecules expressed in tumor microenvironment, are associated to several endocrine side effects. In particular, the use of PD-1/PD-L1 inhibitors is related to a higher incidence of thyroid dysfunction. The most frequent form of thyrotoxicosis is a destructive thyroiditis, which can evolve into hypothyroidism.Patient findings:We report the case of an 85 years-old patient,...

Targeting of PATZ1 by miR-29b is a downstream effect of oncogenic Ras signalling in thyroid cells

Vitiello Michela , Valentino Teresa , De Menna Marta , Serpico Luigia , Mansueto Sonia , Vita Gabriella De , Fusco Alfredo , Fedele Monica

PATZ1, a member of the POZ-ZF protein family of transcription factors is emerging as an important cancer-associated factor that can act either as oncogene or tumour-suppressor depending on the cellular context. Consistent with a tumour-suppressor role in thyroid cells, we have shown that PATZ1 is highly downregulated in anaplastic thyroid carcinomas compared to normal thyroid tissue and is a powerful inhibitor of anaplastic thyroid cancer cell survival, migration, invasiveness...

Oxidative stress in middle age males with osteoporosis: correlation of hormonal pattern and plasma total antioxidant capacity

Raimondo Sebastiano , Tamburrelli Francesco Ciro , Di Segni Chantal , Persano Mariasara , Festa Roberto , Silvestrini Andrea , Meucci Elisabetta , Pontecorvi Alfredo , Mancini Antonio

Male idiopathic osteoporosis is an underestimated disease, despite its clinical and social importance. The biochemical mechanisms are still poorly understood even if the interaction between genetic factors and hormone environment (especially gonadal steroids and GH) plays a undoubtful role. In previous studies we demonstrated low plasma total antioxidant capacity (TAC) in hypogonadal patients. The aim of this study was to investigate oxidative stress as risk factor for bone fr...

Good response to temozolamide therapy in a man with a prolactin secreting pituitary carcinoma

Bilbao Ismene , Coca Mariano Alvarez , Garcia Cristina , Egana Nerea , Aranburu Maite , Yoldi Alfredo , Antunano Luisa , Goena Miguel

Introduction: Pituitary carcinomas are rare and their management is difficult, because they exhibit a continued growth and metastatic dissemination despite of multimodal and aggressive treatments. Temozolamide, has shown a substantial response rates in pituitary carcinomas.We report the case of a patient with a malignant prolactinoma successfully treated with temozolamide.Case report: The patient, a 62-year-old male, consulted with...

Central diabetes insipidus, as the first sign of Langerhans cell histiocytosis in an adult

Egana Nerea , Ruiz Irune , Bilbao Ismene , Aramburu Maite , Yoldi Alfredo , Garcia Cristina , Alvarez Coca Mariano , Luisa Antunano Maria , Goena Miguel

Introduction: Langerhans cell histiocytosis (LCH) is a rare granulomatous disease of unknown etiology. LCH may be localized or be a systemic disease. The diagnosis is frecuent in pediatric age. In adults, infiltration is most frecuently in bones, lungs and skin, and shows particular predilection for hypothalamo-pituitary axis.Case: A 51 years old man was referred due to polyuria of ~15 l of daily urine output. His past medical history revealed bronchiect...
