Background: The diagnostic threshold of β-hydroxybutyrate (BHB) at the moment of hypoglycemia in insulinoma was developed for venous blood many years ago, when there were no alternative ways to measure ketones. Number of works, mainly on patients with diabetes mellitus, found differences in the measurement of this indicator in venous and capillary blood, but the results were contradictory. Moreover, this study was not previously used in the diagnosis of non-diabetic hypoglycemia (NDH) in adults on the territory of the Russian Federation.Aim: To estimate the effectiveness of the method for determining BHB in capillary blood and its place in the diagnosis of NDH.Materials and methods: We conducted an experimental, cross-sectional, comparative study and included patients with suspected NDH who underwent a standard fast test. The BHB level in capillary blood was determined every 6 hours during the fast test and at its completion.Results: Based on the results of the fast test, the participants (n=154) were divided into groups: with hyperinsulinemic variant of NDH and IFRoma (n=98; group 1), with hypoinsulinemic variant of NDH /absence of NDH (n=56; group 2). When comparing the level of BHB at the moment of fasting completion, significant differences were obtained between groups 1 and 2 (p<0.001). According to the ROC analysis, the determination of BHB for differentiation the hyper- and hypoinsulinemic variants of hypoglycemia is characterized by excellent quality of model (AUC=99,1% [98,0%; 100,0%]). The BHB determination in capillary blood has the maximum diagnostic accuracy at a cut-off point of ≤ 1.4 mmol/L (Se 98.0%, Sp 96.4%, PPV 98.0%, NPV 96.4%, Ac 97.4%). Exceeding the diagnostic threshold of BHB was first recorded after 24h of fasting; at the same point, a significant difference was determined when comparing BHB indicators between two consecutive measurements (between 18h and 24h).Conclusion: The BHB determination in capillary blood is a highly sensitive and highly specific additional method for the differential diagnosis of NDH variants. The diagnostic threshold for BHB of capillary blood, which allows differentiating hyper- and hypoketonemic variants of NDH, is ≤1.4 mmol / L. It is advisable to initiate control of BHB in the blood no earlier than 18 hours after the start of the fast test.

Hypogonadism is a condition associated with a decrease in the functional activity of the testicles, accompanied by a decrease in the level of androgens and (or) a violation of the process of spermatogenesis. It is known that androgens and their main representative, testosterone, are of fundamental importance for the development and maintenance of the reproductive and sexual functions of the male reproductive system. At the same time, low testosterone levels are associated with both reproductive and metabolic disorders, including phosphorus-calcium, fat, carbohydrate, and protein metabolism. In addition, to date, data have been accumulated on the correlation of hypogonadism with cardiovascular diseases, which once again emphasizes the problem of testosterone deficiency, especially for patients of the middle and older age groups. However, carrying out testosterone replacement therapy always requires a strict and competent choice of a «target audience» among patients from a specialist. Today, on the pharmaceutical market, there is a wide arsenal of testosterone-containing drugs in various forms for use, which have an unequal «efficacy-safety» profile. In this review, we have analyzed modern approaches to the diagnosis and treatment of hypogonadism, the selection of a target group of patients to obtain the most effective and safe treatment outcome and described testosterone preparations and their dosage forms with potential advantages and disadvantages. Thus, the information presented in the article is aimed at optimizing the management of men with hypogonadism.

Background: Studies of the relationship between obesity and functional bowel disorders, carried out in different age groups, provide conflicting results. It remains unclear what factors are responsible for the transition from a tendency to constipation in children to a tendency to diarrhea in adults with obesity.Aim: To establish factors related to stool consistency as a surrogate marker of colon transit in adolescents with obesity.Materials and methods: A single-center observational cross-sectional study was carried out. We consecutively recruited adolescents, aged 11–17 years with obesity. Socio-demographic characteristics, lifestyle and nutritional characteristics were assessed using questionnaires. Bowel symptoms were assessed using questionnaires and interviews. Stool consistency was assessed using the Bristol Stool Form Scale. Serum concentrations of ALT, AST, bilirubin, cholesterol, glucose, HbA1c, leptin, and insulin were determined. The HOMA-IR index was used to determine insulin resistance.Results: One hundred and ten adolescents with obesity were enrolled in the study. Of these, 69.1% had a pathological consistency of feces, with the prevalence of forms characterizing delayed gut transit (49.1%). The predominance of loose stools was reported by 5.5% of patients. The combination of different forms of stool (unstable stool) was described by 14.5% of adolescents. Hard stools were common among adolescents from single-parent families and adolescents who rarely consume dairy products. The presence of loose stools has been associated with insulin resistance.Conclusion: Most obese adolescents who do not have abdominal complaints have colon transit disorders. Medical professionals should actively ask these patients about stool frequency and properties. With constipation, dietary correction is justified. Research is needed to investigate in-depth gut microbiota as a possible link between obesity and diarrhea.

Background: Disturbance of the morphological and functional properties of the vascular bed in obesity are a serious clinical problem. Basis to their development is endothelial dysfunction. The developed models of obesity in animals using various diets indicate a change in vascular reactivity, however, questions about the stage at which this occurs and what mechanisms are involved in this process remain open, while they are decisive for choosing the correct tactics for correcting dysfunctions.Aim: The aim of the present study is to determine the changes in acetylcholine (ACh)-induced vasodilation of isolated arteries from rats after six weeks of administration of a high-fat diet (HFD).Materials and methods: The experiments were performed on Sprague-Dawley males, which at the age of 8 weeks were divided into 2 experimental groups that were treated for the next 6 weeks in the following manner: 1 - control) with standard dry food; 2 - a group fed with a HFD, the total amount of fat in which was 50%. At finish of the diet, the degree of obesity, biochemical parameters in the blood, and blood pressure were measured. Intravital microscopy of the rat mesentery with video recording was used to study the reactivity of the vessels. The contractile and relaxant responses of the vessels were determined by changes in their diameter.Results: The rats after treatment with the HFD (n=15) had higher body weight and amount of visceral fat, significantly increased blood triglycerides, moderate increases in glucose level in blood and systolic pressure compared with the control (n=15). Relaxation responses of mesenteric arteries, having a diameter of 140 to 300 μm in PSS, were recorded after precontraction by phenylephrine. A decrease in ACh-induced vasorelaxation was obtained, which manifests itself before the development of significant changes in carbohydrate metabolism. Incubation of drugs with the inhibitor of endothelial NO synthase L-NAME led to a pronounced weakening of relaxation in animals on a standard diet, and had little effect on vasodilation in the arteries of rats with the HFD. Vasodilation induced by the administration of sodium nitroprusside (NO donor) did not differ significantly in control and experimental animals, which indicates that the sensitivity of vascular smooth muscle to NO remained practically unchanged. ACh-induced relaxation of arteries in dietary rats did not change when the cyclooxygenase pathway was blocked by diclofenac.Conclusion: Functional changes in the contractile activity of the mesenteric arteries, manifested in the form of a decrease in ACh-induced vasorelaxation, occur after treatment with the HFD when animals had an early stage of obesity development before the onset of pronounced disorders of carbohydrate metabolism. This decrease is mainly due to the disruption of the NO-dependent mechanism underlying ACh-induced relaxation in the norm.

The SARS-CoV-2 virus that caused the 2019 new coronavirus infection (COVID-19) pandemic has posed an unprecedented challenge to the global health system and scientific community. As of this literature review, the infection has claimed more than 6 million lives, and more than 500 million people worldwide have already been infected with SARS-CoV-2. In addition to the basic, pulmonary manifestations of the disease, as well as the severe, life-threatening complications of acute COVID-19, the long-term changes that occur in the postcovid period also affect other systems: endocrine, cardiovascular, nervous, and musculoskeletal. In this literature review, using data from current scientific publications obtained by searching «covid-19 endocrine disorders», «postcovid endocrine disorders» and «postcovid syndrome endocrine disorders» in the MEDLINE (PubMed) database and «endocrine pathology and covid-19», «postcovid and endocrine pathology» and «postcovid syndrome and endocrine disorders» in the e-Library database, we focused on describing and discussing the complications and consequences that SARS-CoV-2 infection can have on the endocrine glands, including the adrenals, thyroid, pituitary, gonads and pancreas.

Background: Assessment of resting energy expenditure (REE) is necessary for the formation of a diet for obesity patients. The «gold standard» for assessment of resting energy expenditure (REE) is indirect respiratory calorimetry. Currently, bioimpedance analyzers are increasingly being used in clinical practice to assess energy consumption at rest, including in obese children. However, the accuracy of such an assessment remains unclear.Aims: To determine the accuracy of the assessment of resting energy expenditure using bioimpedance analysis in children with simple obesity compared with indirect respiratory calorimetry.Materials and methods: Resting energy expenditure was assessed by bioimpedance analysis, Harris-Benedict formula and indirect respiratory calorimetry in all obese children. Comparability of methods was assessed using the Bland-Altman analysis.Results: The study included 320 children aged 7 to 17 years with simple obesity.Resting energy expenditure assessed by bioimpedance analysis was on average 232 kcal lower than the actual. A significant CI (-448 to 912 kcal) was revealed, as well as a large LOA from -514 to 979 kcal. REE calculated by the Harris-Benedict formula on average corresponded to the actual one, and CI varied from -38 to 27 kcal. However, large LOA from -514 to 979 kcal, indicating a high individual variability of resting energy consumption.Conclusions: Bioimpedance analyzers underestimate REE in obese children compared to indirect respiratory calorimetry and the Harris-Benedict formula. Given the significant discrepancies in the accuracy of REE assessment, bioimpedance analysis cannot be considered as an alternative to indirect respiratory calorimetry to assess resting energy in children with simple obesity.

In the modern world, fast food is becoming part of the food culture; herewith, children and teenagers are no exception. A fairly busy lifestyle and lack of time contribute to an increasingly frequent appeal to fast food outlets. Given the national health policies of many countries, including those aimed at keeping up and supporting healthy lifestyles among children and adolescents, the researchers are increasingly focusing on the dependence of obesity on the younger generation’s fascination with fast food. In the proposed review, the authors have analyzed the published data represented in the studies at various levels and regarding a few problems. They are: the establishment of the relationship between a systematic intake of fast food and obesity among children and adolescents; the influence of the distance of fast food outlets from educational institutions on the occurrence and development of metabolic pathologies. Taking into consideration the relationship between fast food consumption by children and adolescents, parents and schools should strictly control their intake of unhealthy foods that leads to the weight gain and obesity-related diseases. Stopping marketing of junk food targeted at kids with eye-catching advertising personalities and gifts, could be one of the ways of childhood’s nutrition revitalizing.

BACKGROUND: Essential arterial hypertension (AH) develops more often in children with accompanying risk factors — obesity, overweight, positive heredity and genetic predisposition.AIM: Study of peculiarities of arterial hypertension clinical course in adolescents with normal body weight, overweight and obesity.MATERIALS AND METHODS: The study was conducted on children with arterial hypertension who received treatment in two hospitals in Voronezh in 2016–2020. A retrospective analysis of the children’s case histories was carried out taking into account the anamnesis, clinical laboratory and instrumental examination data and the pharmacotherapy. Some children underwent polymerase chain reaction genetic testing to determine pathological alleles of genes regulating blood pressure (BP).RESULTS: 96 patients aged 9 to 17 took part in the study. The group with normal body weight included 38 children (39.6%), median age 16.4 (aged 10.7; 17.9), with overweight — 33 people (34.4%), median age 15.2 (aged 12.0; 17.9), with obesity — 25 children (26.0%), median age 14.5 (aged 9.2; 17.9). Obese children developed arterial hypertension at earlier age (p = 0.023). According to blood pressure daily monitoring (BPDM), pathological values of systolic blood pressure (SBP) during the day (above the 95th percentile) among children with normal body weight were observed in 17 patients (44.7%), with excess body weight — in 14 people (42.4%), with obesity — in 16 people (64%), p = 0.031. Accurate difference values between the groups were obtained in terms of time index (TI) of SBP at night (p = 0.006). Time index of diastolic BP during the day > 50% was observed only in the obese children group — 4 people (16%) (p = 0.042). Pathological alleles of the angiotensinogen gene (AGT: 704 T>C), aldosterone synthase gene (CYP11B2: -344 C>T) and endothelial nitrogen synthase type 3 (NOS3: -786 T> C) were identified most frequently during genetic testing in some patients.CONCLUSION: Children with obesity developed earlier arterial hypertension compared to the same-age children with normal body weight and more often had unfavorable type of arterial hypertension according to BPDM. These results can be used to choose individual therapy and to develop special attention as regards certain target organs damage.

A retrospective analysis of the children’s case histories was carried out taking into account the anamnesis, clinical laboratory and instrumental examination data and the pharmacotherapy. Some children underwent polymerase chain reaction genetic testing to determine pathological alleles of genes regulating blood pressure (BP).RESULTS: 96 patients aged 9 to 17 took part in the study. The group with normal body weight included 38 children (39.6%), median age 16.4 (aged 10.7; 17.9), with overweight — 33 people (34.4%), median age 15.2 (aged 12.0; 17.9), with obesity — 25 children (26.0%), median age 14.5 (aged 9.2; 17.9).

BACKGROUND: Depending on the polymorphism of genes that that are involved in metabolism, the response of patients to different types of therapy may differ. Despite the potential effect of rs7903146 TCF7L2 and rs1042712 ADRB2 on changes in body composition in different types of therapy of early carbohydrate metabolism disorders, these associations haven’t been studied yet. AIM: To study the influence of rs7903146 TCF7L2, rs1042714 ADRB2 on changes in body fat composition in different types of therapy of early carbohydrate metabolism disorders.MATERIALS AND METHODS: The study involved patients with overweight or obesity and risk factors for Type 2 Diabetes development. All patients underwent genotyping with the real-time polymerase chain reaction, oral glucose tolerance test and bioimpedancemetry. Further, the patients were divided into two groups. First group kept a diet with the exclusion of simple and limitation of complex carbohydrates and fats. Second group took metformin in addition to the diet. Three months after bioimpedancemetry was performed again.RESULTS: The research involved 73 patients (the mean age 48±12 y.o., the mean BMI 34,27±6,18 kg/m2 ). The diet therapy group consisted of 47 people. Other 26 patients took metformin in addition to the diet. In group of diet, T allele carriers of rs7903146 TCF7L2 were characterized with more decrease in fat mass compared with CC homozygotes (- 7.90 ± 9.46% vs. -1.54 ± 8.98%, p = 0.027). CC genotype carriers of rs7903146 TCF7L2 in group of metformin and the diet had a tendency for more decrease in hip circumference compared with T allele carriers (-4.95 ± 3.34% vs. — 2.5 ± 2.96%, p = 0.064). Carriers of C allele in homozygous state of rs1042714 ADRB2, who took metformin with the diet, demonstrated more decrease in hip circumference (- 5.81 ± 3.00% vs. -2.50 ± 2.7%, p = 0.009), the tendency for decrease in fat mass (-8.28 ± 8.86% vs. — 3.20 ± 5.09%, p = 0.068) and waist circumference (-5.91 ± 4.29% vs. -3.03 ± 4.01 %, p = 0.091) compared with G allele carriers. The association of rs7903146 TCF7L2 and rs1042714 ADRB2 with changes in total body weight was not observed (p> 0.05).CONCLUSION: Single nucleotide polymorphisms rs7903146 TCF7L2 and rs1042714 ADRB2 influence on body fat composition in patients with early carbohydrate metabolism disorders in various types of treatment.
