Introduction: In the literature there are only three papers so far, addressing the impact of thyroid antibodies (Anti-TPO) on pregnancy in Type1 Diabetic Women (DM1) and these present conflicting results. The aim of the study is to evaluate the presence of Anti-TPO in DM1 pregnant women and whether these are related with differences in thyroid function, metabolic control and pregnancy outcome.Methods: In 78 DM1 women with singleton pregnancies Anti-TPO, ...

Introduction-objective: Fas-mediated thyroid cell apoptosis is differentially regulated in autoimmune thyroid disease (AITD) being up-regulated in Hashimoto’s thyroiditis (HT) and down-regulated in Graves’ disease (GD). The soluble form of Fas (sFas), lacking the transmembrane domain due to alternative splicing may inhibit apoptosis by binding to Fas ligand. In this preliminary study we examined whether sFas is also differentially expressed in patients with AITD....

Aim: To evaluate the effect of PPARG2 Pro12Ala, TNFα G(308)A and G(238)A, LIPC C(-514)T, ACE I/D, SLCO1B1 Val174Ala polymorphism on the response to statins therapy in patients with type 2 diabetes mellitus (T2DM).Methods: We consecutively recruited patients with type 2 DM requiring lipid-lowering therapy according to current guidelines. Patients were started on either atorvastatin 10 or 20 mg. After 12 month of st...

Introduction: Recent data indicate that women affected by the polycystic ovary syndrome (PCOS) are at a greater risk for cardiovascular disease (CVD). The objective of this study was to evaluate the effect of the association ethinylestradiol 30 μg–drospirenone 3 mg (DRP/EE30 μg) plus metformin and weight loss on surrogate markers of CVD in PCOS.Methods: Twenty-five young women with PCOS (mean age 22.76±0.83 years, body mass index (BMI...

In this study we employed a novel bioluminescence resonance energy transfer (BRET) biosensor to study the coupling specificity of somatostatin receptor 5 (SST5) and its naturally occurring mutant R240W in living cells. Our previous data demonstrated that SST5 carrying the R240W mutation as well as other mutations in the third intracellular loop maintained the ability to inhibit intracellular cAMP levels similarly to the wild-type but failed to mediate the inhibition of intrace...

The calcium-sensing receptor (CaSR) is a G-protein coupled receptor (GPCR) that maintains systemic calcium homeostasis by detecting alterations in extracellular calcium, which it transduces into signalling changes, mainly via the Gq/11 pathway, leading to a decrease in PTH secretion. The importance of CaSR is highlighted by studies of patients that harbour germline CaSR mutations, which lead to a gain of receptor function in autosomal dominant...

There are potential benefits and risks to receive Granulocyte-Colony Stimulating Factor (G-CSF) as a general treatment in hospital. To assess the clinical effect of G-CSF or non-G-CSF on recovery duration for agranulocytosis patients with hyperthyroidism, we analyzed the overall clinical outcomes by meta-analysis. We included published seven retrospective studies and 1 prospective study. Individual data were obtained from eight trials (376 patients: 215 with G-CSF, 161 with no...

The aim of our study is to identify signalling sensitive residue positions of the glycoprotein hormone receptors (GPHR), especially the thyrotropin receptor (TSHR) on the transmembrane helices (TMH) 5 and 6, knowing to be involved in GPCR activation. We performed modelling driven site-directed mutagenesis to pinpoint residues that are responsible for stabilization of active and inactive conformations of the TSHR.We highlight two amino acids that are high...

Introduction: Extra adrenal paraganglioma (PGL) account for approximately 15% of all pheochromocytoma. Urinary bladder & mediastinum are rarest form of PGL. We present a case of bladder &Mediastinal PGL with a novel mutation in exon 1 of SDHB gene.Case Report: 18 years old male patient was admitted with five years episodic symptoms of headache, sweating, and palpitations, especially after urination. He also complained of postural dizziness for la...
