Introduction: Urinary iodine concentration (UIC) and neonatal thyroid stimulating hormone (neoTSH) concentrations can reflect changes in iodine status and serve as a sensitive marker of iodine intake in pregnancy. As gestational diabetes mellitus (GDM) requires some diet modification, the study aimed to map the situation of iodine intake in women with GDM compared to healthy pregnant women and explore a relationship to thyroid function.Methods: In the tw...

Objective: The aim of this study was to quantitatively estimate SSTR2 in clinically non-functioning pituitary adenomas (CNFAs) with use of RNA in-situ hybridization (ISH) and quantitative real-time RT-PCR and correlate the results of both methods.Methods: A standard histological and immunohistochemical examination was performed on the resected pituitary tumour. Afterwards in-situ hybridization for somatostatine 2 receptor (SSTR2) RNA wa...

It is well known that hypercortisolism is associated with increased morbidity and mortality caused predominantly by vascular and atherosclerotic complications. The effect of hypercortisolism on microvasculature is less known. The aim of this study was to evaluate skin microvascular reactivity (MVR) in relation to arterial hypertension, diabetes mellitus and other possible influencing factors (fibrinolysis, oxidative stress and endothelial function) in patients with Cushing&#14...

Purpose: Although quality of life (QoL) is improved in patients with acromegaly after disease control, QoL correlates only weakly with traditional biomarkers. Our objective is to investigate a potential relation between the new serum biomarker soluble Klotho (sKlotho), GH and insulin-like growth factor 1 (IGF-1) levels and QoL.Methods: In this prospective cohort study, we investigated 54 acromegaly patients biochemically well-controlled on combination tr...

Introduction: Fibroblast growth factor-21 (FGF-21) is a novel regulator of glucose and lipid metabolism and insulin sensitivity. Possible role of FGF-21 in the development of insulin resistance in critically ill patients has not been studied yet.Objective: To study the changes in FGF21 production and adipose tissue and skeletal muscle FGF-21 mRNA gene expression in cardiac surgery patients.Methods: Sixteen patients (16 men, aged 66...

Recent studies have shown that the co-administration of lanreotide (lan) with pegvisomant (peg) was able to normalise IGF1 secretion in patients with acromegaly who were partial responders to somatostatin analogues (SSAs).Fifty seven subjects with acromegaly (mean age 51.6±12.7 years) not previously controlled by SSAs (either treated by SSAs for at least 6 months with IGF1 > ULN, or on peg for at least 3 months) with IGF1 > 1.2 ULN (n...

The usual management at our centre for patients awaiting phaeochromocytoma surgery involves pre-operative titration of alpha blockade with frequent clinic visits for blood pressure (BP) and heart rate (HR) monitoring. The COVID-19 pandemic restricted our ability to consult with patients frequently. To reduce infection risk, we incorporated virtual BP monitoring using a Microsoft Excel template coupled with regular remote consultations. We present a clinical case highlighting o...

Introduction: Adequate hormone replacement therapy in adrenal insufficiency is essential. Patients should have basic knowledge about their condition and what to do in situations which could trigger an adrenal crisis. Education on how and when hydrocortisone replacement therapy should be adjusted as well as instruction and practice an emergency injection are considered important measures to prevent an adrenal crisis. A standardized nurse-led group-based education programme (GEP...

Background: The accuracy of the radiological and laboratory findings used to investigate adrenal masses are not optimal and therefore additional investigation methods, such as fine needle aspiration (FNA) are sometimes needed. Different methods are used for obtaining FNA such as endoscopic ultrasound (EUS), transabdominal ultrasound and computerized tomography (CT)-guided biopsy.Methods: Using a search function incorporated in our institutional pathology...

Medical treatment of acromegaly is based on either suppressing pituitary GH secretion or inhibiting GH action by preventing interaction with its receptor in order to suppress the elevated levels of IGF1. AZP-3813 is a 16-amino acid, bicyclic peptide antagonist of the GH receptor (GHR) derived from peptide sequences discovered using a unique, cell-free in vitro transcription-translation system screened against the human GHR, and that was optimized by rational design to increase...
