[A case of severe hyperparathyroidism in clinical practice. Case report].

Disorders of the mineral balance often determine the symptoms, the severity of the course and the prognosis of many diseases. Primary hyperparathyroidism (PHPT) is a common endocrine disease caused by increased secretion of parathyroid hormone as a result of primary damage to the parathyroid glands. Diagnosis of PHPT is often difficult. Clinical signs of PHPT appear months or years after the onset of the disease, however, the presence of hypercalcemia serves as an early indication of the disease of the thyroid gland. Often, patients are observed for a long time by related specialists (rheumatologists, traumatologists-orthopedists, oncologists), which gives rise to a lot of problems consisting in the lack of adequate treatment and its result, the progression of the disease, disability, and a decrease in the quality of life. Often, patients are observed for a long time by related specialists (rheumatologists, orthopedic traumatologists, oncologists) under the "masks" of various pathologies (osteoporosis, recurrent urolithiasis, etc.), which gives rise to a lot of problems, consisting in an erroneous diagnosis, lack of adequate treatment and its result, progression of the disease, disability, and a decrease in the quality of life. Late diagnosis of PHPT leads to the development of severe complications (osteoporetic fractures, renal failure) and an increased risk of premature death. A clinical case of late diagnosis of PHPT at the stage of pronounced bone complications of the disease, which proceeded under the guise of osteoarthritis, is considered. According to the results of laboratory and instrumental studies, the following were revealed: hypercalcemia, a significant increase in the concentration of PTH, adenoma of the left lower parathyroid gland, hyperparathyroid osteodystrophy, and a decrease in bone mineral density. Surgical treatment was performed - selective parathyroidectomy with the development of hypocalcemia in the early postoperative period, which was stopped by taking calcium supplements and active vitamin D metabolites and is designed to help practitioners of various specialties to understand the issues of diagnosis of PHPT and effective care for patients.

[The study of microcirculation and tissue metabolism as early diagnostic criteria for the risk of diabetic foot development].

AIM: To assess the state of the microvasculature, tissue metabolism and its reserve capabilities for the purpose of early intervention for the prevention of diabetic foot syndrome. MATERIALS AND METHODS: Thirty patients were examined. The patients were divided into three groups depending on the hypoglycemic therapy (metformin, empagliflozin, dapagliflozin). The comparison group consisted of 12 volunteers who did not have carbohydrate metabolism disorders. RESULTS: It was found: the HbA1c indicator significantly decreased in all three groups; significant dynamics in the state of the microvasculature was not observed in any of the three groups; in all groups, there was an improvement in tissue metabolism, however, in this case, no significant dynamics were observed in any of the 3 groups, which indicates the need for provocative tests. CONCLUSION: For this purpose, the authors recommend the method of combined use of laser Doppler flowmetry and laser fluorescence spectroscopy. This technique allows diagnosing the state of the microvasculature and tissue metabolism and its reserve capabilities, using thermal and cold tests.

THE ROLE OF BILE ACIDS IN THE REGULATION OF LIPID AND CARBOHYDRATE METABOLISM IN PATIENTS WITH NONALCOHOLIC FATTY LIVER DISEASE AND DIABETES TYPE2.

Bile acids regulate glucose and lipid metabolism. Aim -determination of total serum bile acids in patients with NAFLD and in combination with type 2 diabetes. To determine the inflammatory markers (nitric oxide, endotoxin, phospholipase A2, malondialdehyde) effects role for the synthesis and transport of bile acids. NAFLD patients with type 2 diabetes observed decrease in synthesis and disruption of transport of bile acids, which is associated with the cell membrane damage by inhibition of enzyme systems, and inflammation.

[NONALCOHOLIC FATTY LIVER DISEASE: DIAGNOSTIC, SYMPTOMS, TREATMENT. GUIDELINES WERE APPROVED BY THE XV GASTROENTEROLOGICAL SCIENTIFIC SOCIETY OF RUSSIA IN 2015].

According to the World Health Organization, it is recorded steady growth of the number of chronic liver diseases, including nonalcoholic fatty liver disease (NAFLD), in recent years. As an independent nosological entity, NAFLD is one of the risk factors for cardiovascular diseases, associated with abdominal-visceral obesity, peripheral insulin resistance (IR), and is regarded as the hepatic component of Metabolic syndrome (MS). Nowadays there are no generally accepted national standards for diagnosis and treatment of NAFLD for physicians, gen- eral practitioners, gastroenterologists in Russia. This was the essential reason in their development. The main reason of The guidelines development is the absence of generally accepted national standards for diagnosis and treatment of NAFLD for physicians, general practitioners, gastroenterologists in Russia. These guidelines are based on the global and local data of treatment experience of NAFLD, recently published in reviews, analytical studies in the literature. Guidelines are intended for physicians, general practitioners, gastroenterologists and contain the description of the preferred approaches to the provision of diagnostic, curative and preventive care of patients NAFLD. The quality of recommendations was grading according to the GRADE approach.
