Serum levels of the soluble receptor for advanced glycation end products (AGEs) are reduced and AGEs increased in hashimoto’s thyroiditis (HT)

Ruggeri Rosaria Maddalena , Vicchio Teresa Manuela , Cristani Maria Teresa , Giovinazzo Salvatore , Campenni Alfredo , Cannavo Salvatore , Trimarchi Francesco

Objective: AGEs, compounds formed by the transformation of proteins, are increased in conditions of oxidative stress and promote inflammation by interacting with their receptor (RAGE) on cell membrane. By contrast, the soluble receptor for AGE (sRAGE), that is proteolytically cleaved from cell surface receptor via matrix metalloproteinases, sequester RAGE ligands and act as a cytoprotective and anti-inflammatory agent. AGEs/sRAGE interaction play a role in the pathogenesis of ...

Serum Interleukin-37 (IL-37) levels were increased and correlated with oxidative stress parameters in Hashimoto’s Thyroiditis (HT) patients

Ruggeri Rosaria Maddalena , Vicchio Teresa Manuela , Alibrandi Angela , Giovinazzo Salvatore , Certo Rosaria , Giuffrida Giuseppe , Trimarchi Francesco , Gangemi Sebastiano , Cristani Mariateresa

Background: IL-37, member of the IL-1 family, is a natural suppressor of immune and inflammatory responses. Increased serum IL-37 levels were observed in several autoimmune diseases, including Graves’ disease. No data on TH are available from the literature.Materials and methods: We enrolled 45 euthyroid HT patients (5 M e 40 F, mean age 38.5±12.6) and 50 age- and sex-matched healthy controls. None was on LT-4 therapy. Smokers, subjects with ki...

The sensitivity and positive predictive value (PPV) of 131I-post-therapy whole body scan is higher than serum Tg values in detecting metastases in early stage of differentiated thyroid cancer patients

Campenni Alfredo , Pignata Salvatore Antonio , Siracusa Massimiliano , Vicchio Teresa Manuela , Trimarchi Francesco , Ruggeri Rosaria Maddalena , Baldari Sergio

The work-up of Differentiated Thyroid Cancer (DTC) patients includes thyroid surgery, thyroid remnant ablation (TRA) with 131-radioiodine and long life follow-up. 131I-post therapy whole body scan (pT-WBS) and thyroglobulin (Tg) are used in identifying metastatic patients. Some authors suggested to use post-surgical Tg (ps-Tg) values in deciding for or against TRA. The aim of our study was to verify the sensitivity and PPV of 131I-pT-WBS compared to serum Tg levels in detectin...

Dietary pattern and oxidative stress markers in hashimoto’s thyroiditis

Ruggeri Rosaria , Giovinazzo Salvo , Giuffrida Giuseppe , Teresa Vicchio Maria , Teresa Cristani Maria , Alibrandi Angela , Campenni Alfredo , Trimarchi University of Messina Francesco

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...

Absence of germline AIP mutations in early onset sporadic somatotropinomas

Gomes Leonor , Prazeres Hugo , Paiva Isabel , Ribeiro Cristina , Rebelo Olinda , Martins Teresa , Lacerda Manuela , Carvalheiro Manuela

Objective: The pathogenesis of pituitary tumours is still incompletely understood. Somatotropinomas occur both sporadically and in the context of familial syndromes, such as multiple endocrine neoplasia type 1 (MEN1), Carney complex (CNC) and isolated familial somatotropinoma (IFS). Recently, germline mutations were reported in AIP (aryl hydrocarbon receptor interacting protein) gene in Finish and Italian families and in Finish patients with apparently sporadic pituitar...

Postsurgical hypoparathyroidism with ‘normal’ PTH

Azevedo Teresa , Martins Teresa , Lemos Manuel , Cunha Nuno , Valido Frederico , Rodrigues Fernando

Introduction: Hypoparathyroidism is characterized by hypocalcemia and low or inappropriately normal levels of PTH. The most common cause of hypoparathyroidism is iatrogenic due to anterior neck surgery. In recent years it was documented that vitamin D insufficiency is widespread.Aim: To investigate the cause of hypocalcemia in thyroidectomized patients with PTH within the reference range.Methods: Retrospective review of clinical re...

ea0020s27.2 | Impact of SNPs on Hormone Function | ECE2009

Impact of SNP on hormone function: FSH receptor

Simoni Manuela

The FSHR is characterised by a large number of SNPs (1636 listed in the NCBI SNP database), mostly located in intronic regions and of unknown heterozygosity rate. Some SNPs, especially those which are nonsynonymous and located in exons have been studied in association with gonadal function.The SNPs at nt position 919 and 2039 in exon 10 are very common (heterozygosity: 0.469) and result in the aminoacid transition Thr/Ala at codon 307 and Asn/Ser ...

Dominance of ovarian follicles is determined by follicle-stimulating hormone receptor (FSHR) and G protein-coupled estrogen receptor (GPER) heteromers

Mechanisms regulating the selection of antral ovarian follicles are poorly understood and supposed to rely on low estrogen levels, decline of follicle-stimulating hormone (FSH) levels and receptor (FSHR) expression on the surface of granulosa cells. These concepts are challenged in-vitro, where apoptosis of human granulosa cells (hGLC) and transfected cell lines is induced by high doses of FSH or FSHR overexpression, while estrogens induce anti-apoptotic signals via n...
