Abstract
Prolactinomas are the most common secreting adenomas of the pituitary. In 20% of cases resistance to dopamine-agonists treatment is observed. Medical therapy resistance causes progression of pathological symptoms of hyperprolactinemia and negative topographic and anatomical changes of prolactinoma. The causes of ineffectiveness of dopamine agonists therapy are not fully understood as well as approaches to managing patients require clarification. Current concepts of resistance are based on the data obtained as a result of surgery or after a period of long-term ineffective therapy. Thus, it is very important to find methods of assessing the sensitivity of prolactin-secreting adenomas to drug therapy before surgical treatment. Genetic and immunohistochemical studies find special place among these methods, making it possible to predict adenoma's response to drug therapy at early diagnostic stage. Obtained results will allow us to form personalized algorithm for managing patients.

Abstract
Given the socio-economic, political and epidemiological changes in the regions of the Russian Federation, the issue of modernizing the training of medical personnel and planning to provide medical organizations with qualified specialists has remained extremely important for several years. The analysis of the survey showed that at present the highly topical issue of staffing the population with endocrinologists and pediatric endocrinologists does not have an unambiguous effective solution. The above measures to reorganize the educational environment require additional revision and correction for the most effective work in the field of medical education. Ultimately, these activities will have an impact on improving the level of training of specialists, improving the personnel situation in the constituent entities of the Russian Federation and improving the quality of medical care for the population of the country.

Abstract
Water balance in the body is achieved by balancing renal and non-renal water losses with corresponding water intake. It is under the control of both the central nervous system, which integrates many parameters of water and electrolyte balance in the body, including inducing important adaptive behavioral responses, and three hormonal systems: vasopressinergic, renin-angiotensin-aldosterone and apelinergic. A lot of research is devoted to the regulation of water-electrolyte metabolism. However, this process is still quite difficult to understand, especially since more and more of its regulators are being discovered over time. One of them is the hormone apelin, an endogenous ligand for the APJ receptor. As is known, the receptor is highly expressed in many organs, such as the brain, heart, liver and kidneys, lungs, and has multidirectional effects.This literature review discusses the main characteristics and features of the regulation of these systems in relation to water-electrolyte metabolism, as well as issues of intersystem interaction and modulation of the effects of apelin.

Abstract
In the Turkish saddle area, there is a wide variety of pathological processes, the vast majority of which present as tumors of various origins (up to 90%). For a clear morphological verification of the diagnosis, it is proposed to use a diagnostic algorithm that includes the stages of differential diagnosis of normal adenohypophysis and neurohypophysis with tumors in the anterior and posterior lobes of the pituitary gland, non-pituitary origin neoplasms, as well as with non-tumor pathological processes (inflammation, cystic masses, and hyperplasia). For morphological diagnosis, histochemical and immunohistochemical methods are recommended using various staining techniques (silver impregnation, periodic acid Schiff reaction) of tissue specimens and antibody panels (pituitary hormones, low-molecular cytokeratins, pituitary transcription factors, neuroendocrine markers, etc.).

Abstract
Prolactin exists in various forms including the monomeric biologically active form (23kDa) and a higher molecular weight form, bound most commonly to IgG, known as macroprolactin (>100kDa). Macroprolactin lacks biological activity and is one of the causes of false-positive results. In Russian Federation the most common method for macroprolactin determination is PEG precipitation test. We had conducted a retrospective analysis of 37 samples of patients with hyperprolactinemia (3 of them were males). The mean age was 30 [25;35] years. Prolactin level was measured by the immunoenzyme method with manual PEG precipitation and TRACE. The mean values found by the immunoenzyme method with manual PEG precipitation were 461,6 [375,0;821,2] mU/l, by TRACE - 449,9 [357,2;749,2] mU/l. The number of patients with normal prolactin levels was 30% (11) confirmed by two methods, high prolactin level at 46% (17). The prevalence of clinical symptoms of hyperprolactinemia was not differ depend the groups. The phenomenon of macroprolactinemia was registered in 32% (12) of patients. In 8 persons of this group normal prolactin level was revealed and in 4 patients hyperprolactinemia was found by TRACE. Measurements of prolactin levels by the TRACE method is useful for correct diagnosis in patients with equivocal results received by traditional method with PEG precipitation.

Abstract
A link between vitamin D deficiency and susceptibility to infectious diseases was suggested over a hundred years ago. Epidemiological studies show a strong association between seasonal fluctuations in vitamin D levels and the incidence of various infectious diseases, including septic shock, acute respiratory infections, and influenza. Our understanding of vitamin D metabolism and its extra-skeletal functions has improved significantly over the past three decades, and the discovery that the vitamin D receptor and 1a-hydroxylase, an enzyme needed to convert vitamin D to its active form, is present in the cells of the immune system, revolutionized in this area. Recent studies have shown that vitamin D regulates the expression of specific endogenous antimicrobial peptides in immune cells, modulates the immune response and the course of autoimmune processes; these actions indicate the potential role of vitamin D in modulating the immune response to various infectious diseases. This publication reviews the literature on the effects of vitamin D on immunity, its potential in the prevention and treatment of viral diseases, with a particular focus on COVID-19.

Abstract
A high prevalence of vitamin D deficiency and its negative consequences for health is identified as area of primary concern for scientists and clinicians worldwide. Vitamin D deficiency affects not only bone health but many socially significant acute and chronic diseases. Observational studies support that pregnant and lactating women, children and teenagers represent the high risk groups for developing vitamin D deficiency. Current evidence highlights a crucial role of vitamin D in providing the fetal life-support system and fetus development, including implantation, placental formation, intra- and postpartum periods. Hypovitaminosis D during pregnancy is associated with a higher incidence of placental insufficiency, spontaneous abortions and preterm birth, preeclampsia, gestational diabetes, impaired fetal and childhood growth, increased risk of autoimmune diseases for offsprings. Potential mechanisms for the observed associations contain metabolic, immunomodulatory and antiinflammatory effects of vitamin D. Epigenetic modifications in vitamin D-associated genes and fetal programming are of particular interest. The concept of preventing vitamin D deficiency is actively discussed, including supplementation in different ethnic groups, required doses, time of initiation and therapy duration, influence on gestation and childbirth. An adequate supply of vitamin D during pregnancy improves the maternal and fetal outcomes, short and long term health of the offspring. Still current data on relationship between maternal vitamin D status and pregnancy outcomes remains controversial. The large observational and interventional randomized control trials are required to create evidence-based guidelines for the supplementation of vitamin D in pregnant and lactating women.

Abstract
OBJECTIVE To present the histological and immunohistochemical characteristics of pituitary lactotroph adenomas (PLAs) resistant to dopamine agonist treatment. SUBJECT AND METHODS The investigators examined paraffin-embedded blocks and histological sections obtained from 19 patients (13 women, 6 men), whose median age was 29 (19, 38) years, after surgical treatment (adenomectomy) for PLAs resistant to dopamine agonist treatment. Immunohistological examination was performed using antibodies against prolactin (PRL), growth hormone (GH), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), type 2 dopamine receptors (DR2), estrogen receptors-α (ERα), the proliferation marker Ki-67, and the endothelial cell marker CD34. RESULTS The expression of PRL by adenoma cells was revealed in all the patients. The coexpression of PRL and GH without clinical and laboratory signs of acromegaly was established in 3 cases. No expression of TSH, ACTH, LH, or FSH was revealed in any cases. Positive immunoreaction using antibodies against DR2 and ERα was detected in 8 and 6 cases, respectively. No expression of any of the studied receptors was found in 6 patients. Ki-67 was more than 3% in 3 patients and higher in patients with supra- or retrosellar growth. There was a positive correlation between the serum level of Ki-67 and that of PRL at the onset of the disease. There were 37 (25, 85) adenoma vessels, as measured by CD34 immunoexpression. It was ascertained that the patients with parasellar adenoma had more tumor vessels than those without parasellar growth of adenoma and that with the latter invading the cavernous vessels, the number of vessels was statistically significantly more. CONCLUSION PLAs resistant to dopamine agonists in addition to PRL (100%) can express GH in 16% of cases are characterized by the immunoexpression of DR2 (42%) and ERα (32%), a low proliferative activity, increased angiogenesis in the adenomas with parasellar growth and invasion into the cavernous sinus.

Abstract
The article describes two clinical cases of severe primary hyperparathyroidism (PHPT) caused by parathyroid carcinoma in young female patients who underwent molecular genetic testing to rule out the hereditary forms of PHPT. In both patients, heterozygous germline nonsense mutations of tumor suppressor gene CDC73 encoding parafibromin (p.R91X and p.Q166X) were identified using next-generation sequencing with Ion Torrent Personal Genome Machine (Thermo Fisher Scientific - Life Technologies, USA). It is the first description of CDC73 mutations in Russia, one of the mutations is described for the first time in the world. Identification of germline mutations in the CDC73 gene in patients with PHPT necessitates regular lifelong screening for other manifestations of hyperparathyroidism-jaw tumor syndrome (HPT-JT), PHPT recurrence due to parathyroid carcinoma as well, and identification of mutation carriers among first-degree relatives.

Abstract
The article briefly reviews the specific features of target-organ lesions in multiple endocrine neoplasia type 1 (MEN1) syndrome and a clinical case of genetically confirmed MEN1 syndrome in a young female patient. Despite the relative rarity of this disease, timely diagnosis, treatment and screening for its main components are very important for the overall prognosis of patients with MEN1 and their first-degree relatives who are MEN1 gene mutation carriers. The described case is noteworthy for a number of specific features. The authors could find no account of optic chiasm glioma within the framework of MEN1 in the literature. Moreover, therapy-resistant somatoprolactinoma engages attention, which points to its aggressive nature with pituitary adenoma that is not been clearly visualized on magnetic resonance imaging. Of interest is the order of detection of neoplasms, in particular the manifestation of hypoglycemic episodes as a sign of organic hyperinsulinism. which have been initially regarded as epileptic seizures, after the use of sustained-release somatostatin analogues for the treatment of acromegaly.

Abstract
Type 1 multiple endocrine neoplasia syndrome (MEN-1) is a rare autosomal dominant disorder caused by mutation in the MEN-1 gene and manifest as a combination of tumours of parathyroid glands, endocrine pancreas, and adenohypophysis. Familial isolated hyperparathyroidism (FIHP) is another rare autosomal dominant disorder characterized by the development ofparathyroid tumours as the sole endocrinopathy within a single family. The notion of FIHP encompasses different hereditary forms of primary hyperparathyroidism, such as a variant of MEN-1 syndrome. This paper is a brief literature review of the problems related to primary hyperparathyroidism, MEN-1, and FIHP. Also, It describes a family presenting with genetically confirmed MEN-1 syndrome, manifest as primary hyperparathyroidism.

Abstract
Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant hereditary disease due to a mutation in the MENI tumor suppressor gene. The risk of the disease in first-degree relatives of MEN1 mutation carriers is 50%. MENI gene mutations are not identified in 10-30% of familiar MEN1 patients and in 60-80% of sporadic MEN1 cases, which can be explained by mutations in the noncoding regions of the MEN1 gene, large gene deletions or mutations in other yet unknown genes. Molecular genetic testing can exclude the diagnosis of MEN1 in patients who do not harbor the MEN1 mutation, thus revealing a MEN1 phenocopy. This obviates the need for annual screening for the early detection of other remaining components of the disease and its risk in progeny.

Abstract
Vitamin D is essential for a vast number of physiologic processes, and thus adequate levels are necessary for optimal health. During childhood and adolescence, an adequate vitamin D status is needed due to its important role in cell growth, skeletal development and growth. Vitamin D is a fat-soluble vitamin that is naturally found in very few foods, is added to others, and is available as a dietary supplement. It is produced endogenously when ultraviolet light strikes the skin. The adequate intake and status of vitamin D greatly depends on age, concomitant diseases and the use of some medications that are covered in-depth in the article. Recent epidemiologic and experimental evidence has suggested that low vitamin D concentrations seem to be significantly associated with all-cause mortality, cardiovascular disease, cancer (mainly breast, prostate and colorectal), hypertension, metabolic syndrome, diabetes mellitus type 1 and type 2. However, the data supporting protective effects of vitamin D supplementation on conditions other than skeletal diseases like rickets, osteoporosis and osteomalacia are very weak, and the large, controlled clinical trials that are in progress now should resolve this issue.

Abstract
Chronic fatigue syndrome is a disease of unexplained feeling of profound fatigue lasting for more than 6 months. This fatigue is
not relieved even after prolonged rest and is exacerbated after physical or mental work. More than 3000 scientific studies had proved that
chronic fatigue syndrome is not a form of depression or hypochondria. It is a real somatic illness that results in professional, social and
individual desadaptation. This article summarizes the contemporary etiological conceptions of this condition.
