Introduction: Adrenocortical carcinoma (ACC) is characterized by the high malignancy of the lesion, poor prognosis and high mortality rate. The surgical treatment and available chemotherapy have generally low efficacy so the search for new therapeutic options is still necessary. Some research indicated that thiazolidinediones (TZDs)–synthetic ligands of peroxisome proliferator-activated receptor γ (PPARγ) have oncostatic action on neoplasm, including endocrine t...

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...

Introduction: Macroforms of prolactin (PRL), the most often macroprolactin (MaPRL), may be the cause of about 25% cases of laboratory diagnosed hyperprolactinaemia. Macroprolactin is usually quantified by polyethylene glycol precipitation, however, the cut-off value (that means the calculated recovery ratio of monomeric PRL) has not been precisely determined and has rather unsatisfactory diagnostic specificity. Therefore, it is suggested that the evaluation of hyperprolactinae...

Background: The NETest, a neuroendocrine multigene transcript ‘liquid biopsy’, is a novel biomarker for GEP-NETs. Current biomarkers are monoanalyte amines or peptides whereas the NETest is a multianalyte signature providing molecular biological information pertinent to clinical disease.Aim: Independently validate the utility of the NETest for the diagnosis of GEP-NETs and identification of disease progression.Material an...

Background: Primary aldosteronism constitutes the most common form of hormonal hypertension. However, it is often mistreated and widely underdiagnosed. Despite the great progress in laboratory technics of adrenal diseases, in the field of primary aldosteronism there is still a need for novel biomarkers that would clarify the diagnosis in equivocal cases. Adropin is a newly discovered protein that may play a role in glucose metabolism and the development of cardiovascular disea...

Primary hypophysitis (PH) is a rare clinical entity usually presenting with headaches, pituitary deficiency, visual field defects and exceptionally with symptoms of cavernous sinus infiltration such as cranial nerve palsies. An internal carotid artery (ICA) occlusion is unusual complication of PH infiltrating the cavernous sinus. A 32-year old woman presented with a 4-year history of recurring headaches, right retro-orbital pain, periodic diplopia and secondary adren...

Background: Primary aldosteronism (PA) is the most frequent cause of hormonal hypertension, typically associated with hypokalaemia. Whereas hypertension with no hypokalaemia can be present in even half of cases, hypokaleamia in normotensive patients is a very rare finding. Mechanisms that act against developing hypertension despite aldosterone excess are at least a few. Some patients with previous low blood pressure increase its values because of hyperaldosteronism, thus still...

Backgroud: ACTH stimulation test is considered the basic diagnostic tool in the diagnosis of nonclassical congenital adrenal hyperplasia due to 21 hydroxylase deficiency (CAH). The cut off of 17OHP stimulation recommended for diagnosis is 10 ng/ml.Aim: To assess whether the recommended threshold of 17OHP after ACTH stimulation confirms nonclassical CAH among woman with hyperandrogenism and elevated basal 17OHP level.Material and Me...

Introduction: Low dose dexamethasone (DEX) androgen suppression test (LDDAST) is considered a tool to distinguish between the sources of androgen excess and to exclude/confirm autonomy of androgen overproduction.Aim: To assess whether 1 mg DST can be used instead of LDDAST.Materials and methods: Thirty-three consecutive women with hyperandrogenism age 18–38 years undergone overnight 1 mg DEX androgen suppression test and LDDAS...

Accumulating evidence suggests that ghrelin’s physiological role extends beyond appetite and energy balance to include reward-seeking behaviour both for food (a natural reward) and chemical drugs. The neurochemical circuitry that links ghrelin to reward behavior and the level of the mesolimbic reward system remains unclear. Ghrelin receptors can be found on the ventral tegmental area (VTA) dopamine neurons. It is not known, however, which dopaminergic projections are rele...
