Introduction: The start of GH (rhGH) treatment in children with GH deficiency (GHD) causes a significant increase in bone turnover and increases height velocity. The increase in IGF1 concentrations during rhGH treatment is a marker of the efficiency of treatment. Bone age delay at baseline is related to GHD and is a good predictor of height velocity during treatment. A significant increase in bone turnover during rhGH treatment results in an increased demand for vitamin D. It ...

Introduction: The majority of secreted hormones influence the whole body, its weigh and constitution as the results of ongoing metabolism. Scientific studies have reported the existence of relationship between the TSH and selected anthropometric parameters such as BMI or body weight.Aim: The aim of the study was to assess the relationship between the value of TSH and selected anthropometric parameters in the group of endocrine patients.<p class="abst...

Objectives: The sodium/iodide symporter (NIS) is a glycoprotein with unique ability of transporting iodine into the thyroid follicle. Apart from the importance in thyroid hormone synthesis, this function of NIS allows the use of radioactive iodine to target residual and metastatic thyroid cancer after thyroidectomy. However, 20–30% of thyroid tumors exhibit lowered expression of NIS, resulting in decreased uptake of radioiodine and inefficient post-surgical therapy. Mecha...

Introduction: Papillary Thyroid Carcinoma (PTC) exhibits activation of MAPK (Mitogen-activated protein kinases) pathway, leading to uncontrolled cellular division and growth. Concomitantly, thyroid tumors exhibit aberrant expression of numerous microRNAs, which are non-coding RNAs that inhibit expression of protein-coding genes. Employing next-generation sequencing (NGS), we revealed comprehensive miRNA profiles of normal thyroid and PTC, and identified putative novel microRNA...

Dopamine agonist cabergoline (CB) is the first-choice treatment in prolactin-secreting adenomas (PRL-omas). It is effective in reducing PRL secretion and tumour size in about 90% of patients by binding dopamine D2 receptor (DRD2). Although no mutations in DRD2 were found, it has been reported that several polymorphisms of this locus associate with alcoholism and schizophrenia, diseases in which dopaminergic system plays an important role. To assess the possible asso...

Objective: The origin of idiopathic isolated secondary adrenal insufficiency (IISAI) is uncertain, however autoimmunity seems to be the most probable cause. Within last eight years the initial number of about 100 such cases, increased in our registry by 250%. We searched for features of autoimmune diseases in our group of patients to prove autoimmune etiology in a majority of these patients.Materials and methods: The material consisted of 260 patients wi...

In foetuses at risk of virilising CAH, prenatal treatment can be offered by administration of dexamethasone (DEX) via the mother in order to prevent genital malformations. Accumulating evidence from animal studies and epidemiological data raise concerns regarding the long term consequences of excess glucocorticoids on the developing foetus. The European study PREDEX is organized as an open, controlled, non-randomised, multicentre trial. The impact of DEX on the general well-be...

The observed increase in the incidence of Hashimoto’s thyroiditis (HT) requires the research on environmental factors that may initiate or model its course. There have been reports of the impact of vitamin D3 deficiency on HT development.Objective: To assess the degree of deficiency of 25OHD3 and the relationship between the disease duration and 25OHD3 levels in patients with HT.Material and methods: 310 people were enrolled i...

Purpose: D631Y is a rare mutation associated with MEN2a in which there is an aspartic acid to tyrosine amino acid substitution at codon 631 in exon 11. Common clinical features of this variant of RET mutation are pheochromocytoma in 50%, medullary carcinoma in 30%, primary hyperparathyroidism is very rare. We present the patient harboring RET D631Y mutation.Clinical case: In April 2017 40-year-old woman was admitted to endocrine department of the Almazov...

BackgroundThe management of post-operative recurrences of ACC remains controversial, although the current guidelines recommend a surgical approach whenever feasible with radical intent.AimThe aim of our study was to evaluate retrospectively the management of recurrences in patients with ACC. We collected data of 106 patients with ACC followed at the San Luigi Hospital for the management of recurrence. Median ...
