[Vascular complications of diabetes mellitus worldwide and in Russia: The path of 100 years. A review].

With the discovery and introduction of insulin, the "palette" of life-threatening conditions for patients with diabetes mellitus has changed dramatically: from diabetic coma of the "pre-insulin era" to severe vascular complications in the modern period. The key risk factors for diabetic angiopathies in diabetes mellitus are poor glycemic control in combination with a long course of the disease. Over the past 30 years, there has been a downward trend in the incidence of late vascular complications of diabetes both worldwide and in Russia. In particular, the frequency of cardiovascular events (myocardial infarctions, strokes, amputations) decreased, and the incidence of several other complications, such as diabetic retinopathy and neuropathy, stabilized. However, the incidence of chronic kidney disease and chronic heart failure is still increasing. The Joslin Medal, awarded to patients over 50, 75 and even 80 years of life with diabetes, reflects success in the fight against this disease.

[Simultaneous living donor pancreas-kidney transplantation in a patient with type 1 diabetes mellitus after program hemodialysis. Case report].

Simultaneous pancreas-kidney transplantation is an effective treatment option for end-stage renal disease with diabetes mellitus. Successful simultaneous pancreas-kidney transplantation allows achieving euglycemia, stabilizing existing microvascular complications and slowing their progression, improving the patient's quality of life, lipid and calcium-phosphorus metabolism, reducing the risks of cardiovascular events. Therefore, in view of the patient's severe general condition due to prolonged intoxication, hyperglycemia and other complications of chronic kidney disease, the earliest possible surgical treatment with minimization of the patient's stay on dialysis therapy is crucial to improve the outcome of transplantation.

[Diabetes mellitus type 2: National Russian guidelines vs real clinical practice].

According to the "Federal Law on the Fundamentals of Protection of the Public Health", medical care for patients should be provided in accordance with National Russian guidelines for the relevant nosology, which are based on the principles of evidence-based medicine. The article presents an analysis of the compliance with the completeness of implementation of National Russian guidelines in the treatment of patients with type 2 diabetes mellitus (DM 2) in real clinical practice. The analysis of the actual state of management of DM 2 patients was carried out from the Federal Register of diabetes as of 01.01.2023. Incomplete compliance with the guidelines on the frequency of measuring glycated hemoglobin, the rate of intensification of hypoglycemic therapy, and the appointment of new classes of hypoglycemic drugs was established. Possible reasons for the identified discrepancies between real practice and guidelines requirements are discussed, as well as possible measures to overcome these discrepancies.

[Ala54Thr polymorphism of the fatty acid transporter gene (FABP2) in patients with type 2 diabetes mellitus in Yakutia].

AIM: To study the contribution of the Ala54Thr genetic polymorphism of the FABP2 gene to the risk of developing type 2 diabetes mellitus among the Yakut population. MATERIALS AND METHODS: The study included participants who filled out a questionnaire approved by the Local Committee on Biomedical Ethics at the Yakut Science Centre of complex medical problems and voluntarily signed an informed consent to conduct a genetic study. The sample consisted of 181 patients of the endocrinological department of the Republican Hospital No. 2 of the State Budgetary Institution "Center for Emergency Medical Care" with a diagnosis of type 2 diabetes. The comparison group was a sample of 336 volunteers without chronic diseases of the Yakut ethnicity. For molecular genetic analysis, genomic DNA samples were isolated from whole blood. Single nucleotide polymorphism was determined by polymerase chain reaction followed by analysis of restriction fragment length polymorphism. RESULTS: Study showed that polymorphism in the FABP2 gene has an impact on anthropometric parameters and blood biochemical parameters. The risk of developing type 2 diabetes was 1.7 times higher in carriers of the Ala/Thr genotype (odds ratio 1.755, 95% confidence interval - 1.212-2.542; p<0.005) compared with carriers of other genotypes. When comparing the average biochemical values, the levels of aspartate transaminase, alanine aminotransferase, glucose and total bilirubin in homozygous carriers of the Ala/Ala genotype were significantly lower than in carriers of other genotypes (р<0.05). Carriers of the heterozygous Ala/Thr genotype (р<0.05) had the highest level in terms of aspartate aminotransferase and alanine aminotransferase. The highest indicator of the average level of HbA1c and an indicator of total bilirubin were carriers of the Thr/Thr genotype (р<0.05). CONCLUSION: The high prevalence of the negative Thr allele among the Yakut population is probably associated with living conditions in the North, as well as in the traditional type of diet.

[Clinical importance of evaluation of circulating miRNA expression and epicardial adipose tissue thickness as predictors of cardiovascular pathology in young patients with type 1 diabetes mellitus].

Cardiovascular disease (CVD) in type 1 diabetes mellitus (T1DM) is preceded by asymptomatic changes in the geometry of the heart. The only symptoms of the beginning of cardiac remodeling and concomitant predictors of an unfavorable cardiovascular prognosis are: thickening of epicardial fat (EAT), secreting a number of adipokines, and cardiospecific miRNAs. To improve the effectiveness of prevention of CVD in young patients with DM1, a search was made for structural-functional and epigenetic markers. AIM: To assess the state of the cardiovascular system according to MRI-heart with T1 mapping in T1DM without CVD. To reveal the relationship of epigenetic markers (circulating miR-126-5p, miR-21-5p) and adipokines with cardiovascular system in T1DM. Suggested personalized approach to patients with T1DM with initial manifestations of joint remodeling and/or exclusion of cardiospecific microRNA. MATERIALS AND METHODS: The study included 40 patients: 30 with T1DM (age 26.2±7.4 years), 10 without T1DM (26.4±8.2). The patients underwent a general clinical examination, bioimpedancemetry, electrocardiography, MRI of the heart with T1 mapping, determination of adiponectin, resistin, visfatin, NT-proBNP, miR-126-5p, miR-21-5p. RESULTS: Patients with T1DM had lower levels of cardioprotective miR-126-5p (p=0.046). According to MRI of the heart in T1DM, signs of vascular remodeling were revealed - thickening of the interventricular septum (p=0.001), posterior wall (p=0.012) and relative size of the walls (p=0.048) of the left ventricle, an increase in EAT density (p=0.001). Diffuse vascular fibrosis was found in 16% of patients from the T1DM group. Also, in T1DM, the expression of visfatin is increased (p=0.036) and adiponectin is reduced (p=0.043). CONCLUSION: Structural and functional changes in the cardiovascular system (including thickening of the EAT), shifts in miR-126-5p expression and adipokines profile are observed already at a young age in patients with T1DM. In T1DM, diffuse vascular fibrosis is detected in 16% of patients. The data obtained were used to identify the group increased risk of developing CVD in T1DM and served as the basis for determining the timing of the start of preventive therapy.

[Obesity and diabetes - are they always together?]

Obesity and type 2 diabetes mellitus (DM 2) are two interrelated metabolic diseases widespread throughout the developed world. However, up to 30% of individuals with a long history of obesity do not have a carbohydrate metabolism disorder. This article presents the results of a multi-year study of adipose tissue biology in obese individuals with DM 2 compared with individuals with the same history of obesity without DM 2. Comparative analysis of hormonal, cellular, and genetic factors in two groups of patients showed that DM 2 occurs in individuals with abnormal proliferation and adipogenic differentiation of mesenchymal stem cells (MSCs) of adipose tissue. It leads to adipocyte hypertrophy and inflammatory infiltration of adipose tissue macrophages, resulting in increased insulin resistance and diabetogenic effects. These disorders are due to abnormal expression of genes responsible for the proliferation and adipogenic differentiation of MSCs. The study of the possible reversibility of abnormal changes in adipose tissue MSCs in obese patients after significant weight loss and DM 2 remission appears to be a promising research direction. The ability to control adipose tissue progenitor cells may represent a new target for treating and preventing metabolic disorders in obesity.

[Sub-analyses of the DAPA-CKD study: new data on the use of sodium-glucose cotransporter type 2 inhibitor in the treatment of chronic kidney disease].

Sodium-glucose cotransporter inhibitors updated their position in the therapy of patients with type 2 diabetes mellitus due to proven nephro- and cardioprotective effects. The DAPA-CKD study, performed among individuals with CKD of various etiologies, was also conducted in a mixed population, including patients without type 2 diabetes, showed the ability of dapagliflozin to reduce the risk of the primary combined endpoint (eGFR<15 ml/min/1.73 m2, the need for chronic dialysis or kidney transplantation, time to renal or cardiovascular death), and certain secondary endpoints. Due to the inclusion of dapagliflozin into the treatment of the patients with CKD of not only the diabetic origin and the expected subsequent significant expansion of the patient population with indications for the use of this drug, the review of the results of the sub-analyses of DAPA-CKD study may be of interest to the clinicians.

[Adipokines and the cardiorespiratory system in young patients with type 1 diabetes mellitus].

Early screening of complications of diabetes mellitus (DM) is one of the priorities for public health. Most patients with type 1 diabetes mellitus (T1DM) are patients of working age. New strategies for the primary prevention of cardiovascular disease (CVD) are needed to prevent their early disability. AIM: To assess the predictive value of adipokines in relation to a personalized approach to the need for an in-depth examination of young patients with T1DM. MATERIALS AND METHODS: The study included 98 patients without CVD: 70 patients with T1DM (mean age 26.4±8.1 years) and 28 patients without DM (mean age 27±9 years). All patients underwent a general clinical examination, the levels of adipokines were determined, ergospirometry, echocardiography, and bioimpedancemetry were performed. RESULTS: Changes in the cardiorespiratory system in patients with T1DM were revealed, in comparison with persons without T1DM: anaerobic threshold was reached faster (p=0.001), maximum oxygen consumption was lower (p=0.048), metabolic equivalent was reduced (p=0.0001). Signs of myocardial remodeling were found in the T1DM group: there was an increase in the relative wall thickness (p=0.001), the posterior wall of the left ventricle (p=0.001), myocardial mass index (p=0.049), in comparison with persons without T1DM. Changes in the adipokines system were revealed: higher levels of resistin (p=0.002) and visfatin (p=0.001), lower level of adiponectin (p=0.040) in T1DM. A positive correlation was found between posterior wall of the left ventricle and visfatin (p=0.014) and a negative relationship between adiponectin and relative wall thickness (p=0.018) in T1DM. CONCLUSION: In T1DM, even at a young age, there are multifactorial changes in the heart, which can be detected even at the preclinical stage. The data obtained can be used to identify groups of patients at high risk of developing dangerous CVD in T1DM, which can form the basis for determining the timing of the start of preventive therapy.

[The National Consensus statement on the management of adult patients with non-alcoholic fatty liver disease and main comorbidities].

The National Consensus was prepared with the participation of the National Medical Association for the Study of the Multimorbidity, Russian Scientific Liver Society, Russian Association of Endocrinologists, Russian Association of Gerontologists and Geriatricians, National Society for Preventive Cardiology, Professional Foundation for the Promotion of Medicine Fund PROFMEDFORUM. The aim of the multidisciplinary consensus is a detailed analysis of the course of non-alcoholic fatty liver disease (NAFLD) and the main associated conditions. The definition of NAFLD is given, its prevalence is described, methods for diagnosing its components such as steatosis, inflammation and fibrosis are described. The association of NAFLD with a number of cardio-metabolic diseases (arterial hypertension, atherosclerosis, thrombotic complications, type 2 diabetes mellitus, obesity, dyslipidemia, etc.), chronic kidney disease and the risk of developing hepatocellular cancer were analyzed. The review of non-drug methods of treatment of NAFLD and modern opportunities of pharmacotherapy are presented. The possibilities of new molecules in the treatment of NAFLD are considered: agonists of nuclear receptors, antagonists of pro-inflammatory molecules, etc. The positive properties and disadvantages of currently used drugs (vitamin E, thiazolidinediones, etc.) are described. Special attention is paid to the multi-target ursodeoxycholic acid molecule in the complex treatment of NAFLD as a multifactorial disease. Its anti-inflammatory, anti-oxidant and cytoprotective properties, the ability to reduce steatosis an independent risk factor for the development of cardiovascular pathology, reduce inflammation and hepatic fibrosis through the modulation of autophagy are considered. The ability of ursodeoxycholic acid to influence glucose and lipid homeostasis and to have an anticarcinogenic effect has been demonstrated. The Consensus statement has advanced provisions for practitioners to optimize the diagnosis and treatment of NAFLD and related common pathogenetic links of cardio-metabolic diseases.

[Prognostic factors for the carbohydrate metabolism normalization in patients with type 2 diabetes mellitus and obesity using liraglutide 3.0 mg per day].

BACKGROUND: Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are innovative drugs that effectively reduce glycemic levels and overweight in patients with type 2 diabetes mellitus (T2DM). However, the criteria for predicting the hypoglycemic effect of this group of drugs have not been practically defined. AIM: To assess the factors contributing to the achievement the glycemia normalization in patients with diabetes mellitus and obesity by adding to antihyperglycemic therapy (AT) a drug from the GLP-1 RA group liraglutide 3.0 mg per day. MATERIALS AND METHODS: A single-center, prospective, non-randomized study was provided. The objects of the study were patients with T2DM and obesity (n=22). Liraglutide 3.0 mg per day was added to the current AT of patients. Initially, the parameters of carbohydrate metabolism, hormones of the incretin system on an empty stomach and during the mixed-meal test, insulin resistance using the euglycemic hyperinsulinemic clamp test, and body composition were studied. After 9 months of therapy, all studies were repeated and a search for possible predictors of the carbohydrate metabolism normalization was made. RESULTS: The body mass index of patients decreased from 42.4 [37.7; 45.0] to 35.9 [33.0; 40.9] kg/m2. Fasting blood glucose and glycated hemoglobin levels decreased from 9.02 [7.40; 11.37] mmol/L and 7.85 [7.43; 8.65]% up to 5.90 [5.12; 6.18] mmol/L and 6.40 [5.90; 6.60]%, respectively. 14 (63.6%) patients reached normoglycemia. Insulin resistance according to the clamp test did not change over the study. Basal concentrations of oxyntomodulin, glycentin and the area under the GLP-1, oxyntomodulin, glycentin curve significantly decreased 9 months after liraglutide administration. The prognostic marker of the achievement of normoglycemia during therapy with liraglutide 3.0 mg/day is the level of endogenous GLP-15.5 pmol/L before the appointment of arGPP-1 therapy. CONCLUSION: The concentration of endogenous GLP-1 before the appointment of liraglutide therapy at a dose of 3.0 mg per day can be used for prediction the drug hypoglycemic effect and achieving normoglycemia possibility.

[Adrenal incidentaloma. Part 2. Modern concepts of computed tomography semiotics of adrenal gland incidentalomas: algorithm of differential diagnosis].

While accidentally detecting an adrenal gland lesion (incidentaloma) during a routine computed tomography (CT) scan, the radiologist should correctly interpret revealed changes. The most common lesion is adenoma with high lipid content, but a lipid poor adenoma, pheochromocytoma, adrenocortical cancer, metastasis and other less common adrenal diseases are also worth of attention and require detailed knowledge of their CT semiotics. The article presents criteria of differential diagnosis of the adrenal incidentalomas on the basis of which an algorithm of differential diagnosis was proposed for the most common adrenal lesions.

[Advanced glycation end products and oxidative stress as a basis for metabolic abnormalities in patients with type 1 diabetes after successful simultaneous pancreas-kidney transplantation].

AIM: To compare advanced glycation end-products (AGE, RAGE) and 3-nitrotyrosine (3-HT) in patients with DM 1 after successful simultaneous pancreas-kidney transplantation (SPK) and kidney transplantation alone (KTA). To assess relationship between levels of AGE, RAGE, 3-HT and renal transplant (RT) function, carbohydrate and mineral metabolism. MATERIALS AND METHODS: The study included 58 patients who received kidney transplantation in end-stage renal disease (ESRD). 36 patients received SPK. There were performed routine laboratory, examination of AGE, RAGE, 3-NT, parathyroid hormone (PTH), 25(OH)vitamin D, calcium, phosphorus, FGF23, osteoprotegerin (OPG), and fetuin-A levels. RESULTS: All patients after SPK reached normoglycemia (HbA1c 5.7 [5.3; 6.1] %; C-peptide 3.24 [2.29; 4.40] ng/ml) with the achievement of significant difference vs patients after KTA. Arterial hypertension (AH) was more frequent in recipients of SPK before transplantation than after (p=0.008). AH also persisted in greater number of cases in patients after KTA than after SPK. Patients after SPK had higher AGE (р=0.0003) and lower RAGE (р=0.000003) levels. OPG in patients after SPK was significantly higher (р=0.04). The correlation analysis revealed significant positive correlation between 3-HT and OPG (p0.05; r=0.30), RAGE and eGFR (r=-0.52), HbA1c (r=0.48), duration of AH (r=0.34), AGE with HbA1c (r=0.51). CONCLUSION: The results of the "metabolic memory" markers analysis may indicate their contribution to the persistence of the metabolic consequences of CKD and DM 1 after achievement of normoglycemia and renal function restoration and their possible participation in development of recurrent nephropathy, vascular calcification, and bone disorders.

[Angiogenesis system, as a part of endothelial dysfunction in patients with diabetes mellitus type 2: relationship with obesity].

AIM: To investigate parameters of angiogenesis system in patients with diabetes mellitus and their relationship with obesity. MATERIALS AND METHODS: 104 patients with diabetes mellitus type 2 were included in the study. Patients were divided in 2 groups: Obesity+ (body mass index30 kg/m2;n=63) and Obesity- (body mass index 30 kg/m2;n=41). In all patients was performed clinico-diagnostical examination. mRNA expression levels of vascular endothelial growth factor (VEGF), its receptors flt-1 (fms-like tyrosine kinase 1), KDR (human kinase insert domain receptor) were determined in blood mononuclear cells. RESULTS: There were no statistically significant differences in investigated parameters between study groups. mRNA expression level of VEGF was slightly lower in men compared to women: 0.19 (0.14; 0.32)vs0.28 (0.12; 0.4) respectively,р=0.2236. MRNA expression level of flt-1 was lower in men compared to women: 0.14 (0.04; 0.3)vs0.25 (0.12; 0.38),р=0.0321 (statistically significant). We found statistically significant correlations of mRNA expression level of VEGF with mRNA expression level of flt-1 and KDR. Also we found strong positive correlations of BMI and mRNA expression levels VEGF, flt-1, KDR (r=0.86107,r=0.86125,r=0.86112, respectively,p0.001). CONCLUSION: Results of the study displayed relationship of obesity and angiogenesis system condition in patients with diabetes mellitus type 2. Further investigations are perspective for the future as a way to new therapeutical approach of obesity and its complications treatment.

[Advantages of therapy with sodium glucose cotransporter type 2 inhibitors in patients with type 2 diabetes mellitus in combination with hyperuricemia and gout].

Currently, only two drugs for reducing uric acid (UA), allopurinol and febuxostat, are registered in the Russian Federation, but their use does not allow to achieve the target level of UA in all cases. According to the results of numerous randomized trials, hyperuricemia and gout are associated with the corresponding components of the metabolic syndrome, including diabetes mellitus. The influence of factors is due to the need to search for new drugs that have a complex effect on several components of metabolic syndrome at once. Potentially attractive in this regard is a new group of drugs for the treatment of type 2 diabetes mellitus inhibitors of the sodium-glucose cotransporter of type 2, which, in addition to the main hypoglycemic actions, showed positive effects on the cardiovascular system, kidneys, as well as lowering UA.

[Obesity without diabetes: the role of hormonal regulation].

AIM: Obese patients without diabetes present an interesting phenotype to explore protective mechanisms against type 2 diabetes (T2D) development. In our study we looked for specific hormonal features of obese patients without T2D. MATERIALS AND METHODS: We included 6 groups of patients with different metabolic profiles (n=212): controls with BMI25 kg/m2, HbA1c6%, age 30 years; patients with 25BMI30 kg/m2and HbA1c6%; patients with 25BMI30 kg/m2and HbA1c6%; patients with BMI30 kg/m2and HbA1c6% (+ Obesity - T2D) obese patients without T2D or prediabetes; patients with BMI30 kg/m2and newly-diagnosed T2D/prediabetes, HbA1c6%; patients with known history of T2D on glucose-lowering drugs with BMI30 kg/m2. Insulin, GLP-1, GIP were measured during glucose-tolerance test at 0, 30 and 120 minutes; insulin resistance (IR) was assessed by HOMA-IR. RESULTS: Waist circumference was bigger in patients with obesity despite their metabolic profile comparing to patients without obesity (p0.001). Waist-to-hip ratio was similar in patients with different metabolic status. According to IR + Obesity - T2D group had intermediate position: IR was higher in that group comparing to people without obesity, but was less that in patients with obesity and HbA1c6% (p0.001). + Obesity - T2D group had the most potent baseline insulin secretion, assessed by НОМА-%band the highest postprandial secretion, measured by insulinogenic index among all patient groups with obesity (p0.001). There was no significant difference in GLP-1 secretion; GIP secretion was higher in patients with BMI30 kg/m2comparing to people with BMI30 kg/m2(p0.01).

[Adrenal incidentaloma. Part 1. Computed tomography of adrenal incidentaloma: the possibilities and difficulties of differential diagnosis].

The adrenal incidentaloma is a lesion of a different etiology and found incidentally in patients who underwent a diagnostic study not about the disease of this organ. Lesions can be both hormonally inactive and hormonally active, can arise from different zones of the adrenal gland or have non-specific organ affiliation, can be benign or malignant. Computed tomography characterization of these lesions, especially the differential diagnosis of benign and malignant, is extremely important for the correct diagnosis in order to provide adequate management of the patient. The article presents the key computed tomography criteria that allow radiologist to characterize the lesion most accurately and consider appropriate diagnosis.

The article presents data on drug interaction of drugs.

Latent Inflammation and Defect in Adipocyte Renewal as a Mechanism of Obesity-Associated Insulin Resistance.

Obesity is a major risk factor for type 2 diabetes and metabolic syndrome and an essential medical and social problem. In the first part of the review, we briefly highlight the biochemical basis of metabolic disbalance in obesity and evolution of our views on the mechanisms of insulin resistance development in insulin-sensitive tissues. Because obesity relates to the disturbance in the normal physiology of fat tissue, the second part of the review focuses on latent inflammation that develops in obesity and is supported by immune cells. Finally, the problem of adipocyte hypertrophy, reduced regenerative potential of fat progenitor cells, and impaired renewal of fat depots is discussed in the context of type 2 diabetes pathogenesis.

[Diabetes epidemiology in Russia: what has changed over the decade?]

The National diabetes register (NDR) was created as unified dynamic database in online format. It allows providing clinical and epidemiological monitoring of diabetes mellitus (DM) in the whole country. AIM: To analyze the epidemiological characteristics of diabetes over the past decade, to access the dynamics of the prevalence of acute (coma) and chronic (micro - and macrovascular) complications of DM. MATERIALS AND METHODS: The object of the study was the depersonized NDR database of DM patients. It consists of 84 regions of the Russian Federation (RF), included in the online registry system on 01.01.2019. RESULTS AND DISCUSSION: The total number of patients with DM in RF on 01.01.2019 was 4 584 575 (3.12% of the population), comprising 256.2 thousand patients with T1DM, 4.24 million with T2DM, 89.9 thousand other types of DM. Since 2000, the number of DM patients in RF has grown 2.2 times. 34.7% patients with T1DM reached target level of HbA1c.

[Glycemia normalization in patients with obesity and type 2 diabetes mellitus: bariatric surgery vs pharmacological therapy].

AIMS: To compare glucose - lowering and weight reduction capacity of bypass operations (gastric bypass (GB), biliopancreatic diversion (BPD) vs GLP-1 agonist liraglutide 3.0 mg (models of maximum incretin effect) for 6 months. MATERIALS AND METHODS: 46 patients with type 2 diabetes and long history (≥10 years) of obesity were divided into 2 groups: surgery - group (n=23) and liraglutide - group (n=23), where liraglutide 3.0 mg in dose - escalation manner was added to baseline glucose - lowering therapy. Anthropometric parameters, HbA1c and insulin resistance (IR) by hyperinsulinemic euglycemic clamp (M-value) were measured before and 16 weeks after the intervention. With the stabilization of glycemia (≤6.5 mmol/l at fasting state, ≤8 mmol/l postprandial) the initial glucose - lowering therapy was canceled. RESULTS AND DISCUSSION: Both surgery and liraglutide 3.0 mg provided target HbA1c in 16 weeks. Bypass operations led to elimination of glucose - lowering therapy in 82.6% patients due to a more significant weight reduction and decrease in IR. In liraglutide - group previous glucose - lowering therapy was cancelled in 78.3% patients, mainly receiving baseline mono - and two - component therapy. The most significant difference between interventions was achieved in BMI (-8.9 kg in surgery group vs -3.8 kg in liraglutide group, p.
