Introduction: Measurement of copeptin is proposed for use in the differential diagnosis of polyuric syndrome.Aims: To evaluate the diagnostic value of copeptin levels in patients with polyuria syndrome.Materials and methods: The study included 17 patients with central diabetes insipidus (CDI), 3 patients with nephrogenic diabetes insipidus (NDI), 7 patients with primary polydipsia (PP) and 26 control subjects. In all individuals bl...

Introduction: Patients with resistant prolactinomas have reduced fertility todue to chronic anovulation and hypoplasia of uterus and ovaries. SERM tamoxifen demonstrates a recovery of menstrual function and ovulation and reverses the hypoplasia of the uterus. The mechanism of its action in case of hyperprolactinemia is not clear yet.Aim: To study the role of kisspeptin in restoration of reproductive function in patients with prolactinomas treated by tamo...

Introduction: Acromegaly impairs the hypothalamic-pituitary-gonadal (HPG) axis and reproductive function that causes amenorrhea and infertility. The mechanism of these disturbances is not clear. Kisspeptin and neurokinin B are very important neuropeptides regulating cyclic LH release from pituitary due to stimulation of GnRH.Aim: The purpose of this study was to assess the role of key reproductive neuropeptides in regulation of menstrual function in pati...

Introduction: In recent years, more attention is driven to the cause of hereditary forms of pituitary adenomas. Although for most cases causal genes are not discovered yet, AIP mutations are the most prevalent.Materials and Methods: Case descriptions, high-parallel sequencing using a gene panel (MEN1, CDKN1B, PRKAR1A, GNAS, AIP, SDHA, SDHB, SDHS, SDHD, PRKCA, CDKN2C, CDKN2A, POU1F1, PTTG2).Case description: Index ...

Introduction: Most of the work on the analysis of molecular genetic defects in pituitary adenomas devoted to the study of 1–2 candidate genes. The high-performance parallel sequencing is more promising.Materials and Methods: There were a total of 26 families (58 patients, 36 (62.1%) men and 22 (37.9%) women) with pituitary adenomas secretion of various types. The number of families with homogenous type was 17 (somatotropinomas 13, prolactinomas 2, c...

Introduction: Medical therapy with dopamine agonists is the best treatment for prolactinomas of any size or invasiveness and restores ovulatory cycles in 80–90% of patients. Cabergoline currently suggested nearly exclusively rather than other dopamine agonists due to its excellent tolerability and long half-life. That is why the question of safety using of this drug during pregnancy and embryo-fetal development is actual.Aim: The aim of the study is...

Introduction: Somatotropinomas are typically recognized when GH excessively secretion causes acromegaly. «Silent» somatotroph adenomas (immunohistochemical evidence of GH excess without biochemical or clinical evidence) and «clinically silent» somatotroph adenomas (immunohistochemical and biochemical evidence without clinical evidence) have occasionally been reported. The relative frequency of each presentation is unknown.<p class="abst...

TSH-secreting pituitary adenoma (thyrotropinoma) is a rare (0.5% of all pituitary adenomas) and usually benign pituitary lesion, arising from the monoclonal expansion of neoplastic thyrotrophes. Thyrotropinoma usually presents with symptoms thyrotoxicosis (milder compared to those originating from the primary thyroid disorders) and mass effects of the pituitary tumour.Aim: To describe the clinical course of thyrotropinoma presented with paroxysmal atrial...

Introduction: The important aspect of vitamin D (vitD) sufficiency is the impact of chronic diseases and medications, which disturb the metabolism of vitD. Bone pathology is common in diseases of the endocrine system, so the determining the status of vitD in various endocrine diseases and comparing it to otherwise healthy controls is of particular interest.Materials and methods: The study included 16 patients with type 2 diabetes mellitus (T2DM), 23 pati...

Introduction: Numerous literature sources indicate the potential role of hyperprolactinemia in the development of obesity. Prolactin modulates the functional activity of several enzymes and transporters in adipose tissue and islets of Langerhans, potentially influencing fat and glucose metabolism. On the other hand, elevated prolactin level may induce eating disorders due to dysfunction of dopaminergic regulation of the CNS. We present a clinical case of a man with morbid obes...
