Hypothalamic neuropeptides as biomarkers for water-electrolyte disturbances. Introduction Diabetes insipidus is a rare condition characterized by excretion of large amounts of dilute urine and increased thirst. Nephrogenic diabetes insipidus (NDI) is caused by the inability of the kidneys to concentrate urine in response to vasopressin.Aim: The aim of our case report is to present the patient with NDI and to report the data on physiological changes in hy...

Introduction: Diabetes insipidus (DI) is a rare condition characterized by excretion of large amounts of dilute urine and increased thirst due to deficiency or renal resistance of antidiuretic hormone (ADH). DI is often difficult to diagnose reliably and accurately, especially in patients with partial DI.Aim: The aim of our case report is to present the patient with partial diabetes insipidus and to report the results of water deprivation and hypertonic ...

Introduction: Transnasal adenomectomy is the main treatment for various pituitary adenomas. The hypothalamic-pituitary region is the site of synthesis and secretion of several hormones that have a direct effect on sodium-water metabolism, which leads to its frequent violation with the development of central diabetes insipidus and severe transient hyponatremia, the latter of which is the second most important cause of rehospitalization in the postoperative period. Currently, th...

Introduction: The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is characterized by hypotonic and euvolemic hyponatremia along with urinary hyperosmolarity, resulting from antidiuretic hormone (ADH) release in the absence of adequate stimuli.Case report: A 59-year-old woman, presented with complaints of constant thirst, general weakness, memory loss, episodes accompanied by headaches, leg cramps, increased blood pressure. From the a...

Introduction: Water-electrolyte disorders are serious complications after transnasal adenomectomy for formations of the hypothalamic-pituitary region. The purpose of this work was to evaluate the incidence of postoperative hyponatremia in the tactics of active control of sodium levels in the blood.Materials and methods: The study included the results of a dynamic study of blood sodium levels in 53 patients (mean age 46.6 years [min 19; max 68]) with pitu...

Introduction: According to recent studies, fluid and electrolyte disturbances complicate the course of transnasal adenomectomy for pituitary adenomas in 13–30% of cases and are associated with a high risk of neurological complications and increased mortality. Neuropeptides discovered in recent decades (apelin, copeptin, oxytocin, brain natriuretic peptide) in many studies demonstrate their significant effect on the regulation of water-electrolyte metabolism, which makes t...
