Standards of specialized diabetes care. Edited by Dedov I.I., Shestakova M.V., Mayorov A.Yu. 9th edition

Dear Colleagues! We are glad to present the 9th Edition (revised) of Standards of Diabetes Care. These evidence-based guidelines were designed to standardize and facilitate diabetes care in all regions of the Russian Federation. The Standards are updated on the regular basis to incorporate new data and relevant recommendations from national and international clinical societies, including World Health Organization Guidelines (WHO, 2011, 2013), International Diabetes Federation (IDF, 2011, 2012, 2013), American Diabetes Association (ADA, 2018, 2019), American Association of Clinical Endocrinologists (AACE, 2019), International Society for Pediatric and Adolescent Diabetes (ISPAD, 2014, 2018) and Russian Association of Endocrinologists (RAE, 2011, 2012, 2015). Current edition of the “Standards” also integrates results of completed randomized clinical trials (ADVANCE, ACCORD, VADT, UKPDS, SAVOR, TECOS, LEADER, EXAMINE, ELIXA, SUSTAIN, DEVOTE, EMPA-REG OUTCOME, CANVAS, DECLARE, CARMELINA, REWIND, etc.), as well as findings from the national studies of diabetes mellitus (DM), conducted in close partnership with a number of Russian hospitals. Latest data indicates that prevalence of DM in the world increased during the last decade more than two-fold, reaching some 463 million patients by the end of 2019. According to the current estimation by the International Diabetes Federation, 578 million patients will be suffering from diabetes mellitus by by 2030 and 700 million by 2045. Like many other countries, Russian Federation experiences a sharp rise in the prevalence of DM. According to Russian Federal Diabetes Register, there are at least 4 584 575 patients with DM in this country by the end of 2018 (3,1% of population) with 92% (4 238 503) – Type 2 DM, 6% (256 202) – Type 1 DM and 2% (89 870) – other types of DM, including 8 006 women with gestational DM. However, these results underestimates real quantity of patients, because they consider only registered cases. Results of Russian epidemiological study (NATION) con- firmed that only 54% of Type 2 DM are diagnosed. So real number of patients with DM in Russia is 9 million patients (about 6% of population). This is a great long-term problem, because a lot of patients are not diagnosed, so they don’t receive any treatment ant have high risk of vascular complications. Severe consequences of the global pandemics of DM include its vascular complications: nephropathy, retinopathy, coronary, cerebral, coronary and peripheral vascular disease. These conditions are responsible for the majority of cases of diabetes-related disability and death. In сurrent edition of the “Standards”: New goals of glycemic control for the elderly, based on the presence of functional dependence, as well as for pregnant women, children and adolescents, are given. Added a snippet that describes the continuous glucose monitoring. Only low-density lipoprotein cholesterol level is used as a target for lipid metabolism. Proposes more stringent target levels of blood pressure. It also features updated guidelines on stratification of treatment in newly diagnosed Type 2 diabetes: the excess of the initial level of HbA1c over the target level was used as a criterion. In the recommendations for the personalization of the choice of antidiabetic agents, it is taken into account that in certain clinical situations (the presence of atherosclerotic cardiovascular diseases and their risk factors, chronic heart failure, chronic kidney disease, obesity, the risk of hypoglycemia) certain classes of hypoglycemic agents (or individual drugs) have proven advantages. Recommendations for psychosocial support are added. The position of metabolic surgery as a method of treatment of DM with morbid obesity is updated. Recommendations for diagnostic and treatment of hypogonadism syndrome in men with DM are added. For the first time, evidence levels of confidence and credibility levels of recommendations for diagnostic, therapeutic, rehabilitative and preventive interventions based on a systematic review of the literature are given in accordance with the recommendations of the Center for Healthcare Quality Assessment and Control of the Ministry of Health of the Russian Federation. This text represents a consensus by the absolute majority of national experts, achieved through a number of fruitful discus- sions held at national meetings and forums. These guidelines are intended for endocrinologists, primary care physicians and other medical professionals involved in the treatment of DM. On behalf of the Working Grou

Deciphering the function of canonical Wnt signals in development and disease: conditional loss- and gain-of-function mutations of β-catenin in mice

Wnt signaling is one of a handful of powerful signaling pathways that play crucial roles in the animal life by controlling the genetic programs of embryonic development and adult homeostasis. When disrupted, these signaling pathways cause developmental defects, or diseases, among them cancer. The gateway of the canonical Wnt pathway, which contains >100 genes, is an essential molecule called β-catenin (Armadillo in Drosophila). Conditional loss- and gain-of-function mutations of β-catenin in mice provided powerful tools for the functional analysis of canonical Wnt signaling in many tissues and organs. Such studies revealed roles of Wnt signaling that were previously not accessible to genetic analysis due to the early embryonic lethality of conventional β-catenin knockout mice, as well as the redundancy of Wnt ligands, receptors, and transcription factors. Analysis of conditional β-catenin loss- and gain-of-function mutant mice demonstrated that canonical Wnt signals control progenitor cell expansion and lineage decisions both in the early embryo and in many organs. Canonical Wnt signaling also plays important roles in the maintenance of various embryonic or adult stem cells, and as recent findings demonstrated, in cancer stem cell types. This has opened new opportunities to model numerous human diseases, which have been associated with deregulated Wnt signaling. Our review summarizes what has been learned from genetic studies of the Wnt pathway by the analysis of conditional β-catenin loss- and gain-of-function mice

Morphological abnormalities of peripheral blood cells among patients with COVID-19 disease

Purpose: The hematological changes in COVID-19 patients continue to receive great attention, especially in the field of public health. To our knowledge, coronavirus disease may be identified based on the severity of illness, and the study of peripheral blood smears may offer important information to facilitate the identification. Thus, we evaluated the morphological abnormalities (atypical and immature lymphocytes, lymphocytes with micronuclei, various nuclear abnormalities among erythrocytes) and quantitative changes in peripheral blood cells among 48 individuals with COVID-19 disease. Methods: The present study is a retrospective analysis of 48 individuals, including 24 hospitalized patients diagnosed with COVID-19 disease. The blood smears of all patients were subjected to a hematological examination to identify various morphological abnormalities in white and red blood cells. In addition, a micronucleus test was conducted to assess the incidence of chromosomal damage in lymphocytes. Furthermore, the complete blood count (CBC) was performed to evaluate changes in peripheral blood cells, particularly the differential total leukocyte count, which could indicate the immune response against viral infection in COVID-19 patients. Results: The findings of the hematological study conducted on patients diagnosed with COVID-19 disease revealed neutrophilia, eosinophilia, mild monocytosis, decreased hematocrit level, elevated erythrocyte sedimentation rate (ESR), and immature leukocytes. It was observed that patients who were infected with coronavirus demonstrated mild thrombocytopenia. Furthermore, the micronucleus test indicated the presence of immature cells with micronuclei among lymphocytes and numerous nuclear abnormalities in red blood cells. These results help to shed light on the hematological changes that occur in COVID-19 patients, and could potentially contribute to the development of more effective treatments for the disease. Conclusions: The examination of complete blood counts (CBCs) in conjunction with peripheral blood smears offers a potential means of identifying the impact of SARS-CoV-2 infection on the hematopoietic and immune systems, thereby providing early indications of inflammation. Based on a study, it has been suggested that SARS-CoV-2 may affect red and white blood cells causing morphological alterations thereby establishing a corresponding relationship with disease severity

Prevalence of Pretreatment HIV-1 Drug Resistance in Armenia in 2017–2018 and 2020–2021 following a WHO Survey

The increased antiretroviral therapy (ART) coverage of patients in the absence of routine genotyping tests and in the context of active labor migration highlight the importance of HIV-1 drug resistance (DR) surveillance in Armenia. We conducted a two-phase pretreatment DR (PDR) study in 2017–2018 (phase I; 120 patients) and 2020–2021 (phase II; 133 patients) according to the WHO-approved protocol. The analysis of HIV-1 genetic variants showed high degrees of viral diversity, with the predominance of A6. The prevalence of any PDR was 9.2% in phase I and 7.5% in phase II. PDR to protease inhibitors was found only in 0.8% in phase II. PDR to efavirenz and nevirapine was found among 5.0% and 6.7% of patients in phase I, and 6.0% and 6.8% of patients in phase II, respectively. The prevalence of PDR to nucleoside reverse-transcriptase inhibitors decreased from 5.0% in phase I to 0.8% in phase II. In addition, we identified risk factors associated with the emergence of DR—male, MSM, subtype B, and residence in or around the capital of Armenia—and showed the active spread of HIV-1 among MSM in transmission clusters, i.e., harboring DR, which requires the immediate attention of public health policymakers for the prevention of HIV-1 DR spread in the country

Standards of specialized diabetes care. Edited by Dedov I.I., Shestakova M.V. (7th edition)

We are glad to present the 7th Edition of Standards of Diabetes Care. These evidence-based guidelines were designed to standardize and facilitate diabetes care in all regions of the Russian Federation. The Standards are updated on the regular basis to incorporate new data and relevant recommendations from national and international clinical societies, including World Health Organization Guidelines (WHO, 2011, 2013), International Diabetes Federation (IDF, 2011, 2012, 2013), American Diabetes Association (ADA, 2012, 2015), American Association of Clinical Endocrinologists (AACE, 2013), International Society for Pediatric and Adolescent Diabetes (ISPAD, 2014) and Russian Association of Endocrinologists (RAE, 2011, 2012). Current edition of the ?Standards? also integrates results of completed randomized clinical trials (ADVANCE, ACCORD, VADT, UKPDS, etc.), as well as findings from the national studies of diabetes mellitus (DM), conducted in close partnership with a number of Russian hospitals. Latest data indicates that prevalence of DM increased during the last decade more than two-fold, reaching some 387 million patients by the end of 2014. According to the current estimation by the International Diabetes Federation, 592 million patients will be suffering from DM by 2035. These observations resulted in the UN Resolution 61/225 passed on 20.12.2006 that encouraged all Member States "to develop national policies for the prevention, treatment and care of diabetes". Like many other countries, Russian Federation experiences a sharp rise in the prevalence of DM. According to Russian State Diabetes Register, there are at least 4.1 million patients with DM in this country. However, the epidemiological survey conducted by the Federal Endocrinology Research Centre during 2002-2010 suggests that actual prevalence is 3 to 4 times greater than the officially recognized and, by this estimate, amounts to 9-10 million persons, comprising 7% of the national population. Severe consequences of the global pandemics of DM include its vascular complications: nephropathy, retinopathy, coronary, cerebral and peripheral vascular disease. These conditions are responsible for the majority of cases of diabetes-related disability and death. Current edition of the "Standards" emphasizes the patient-oriented approach in making decisions on therapeutic goals, such as levels of glycaemia and blood pressure. It also features updated guidelines on the management of vascular complications. This text represents a consensus by the absolute majority of national experts, achieved through a number of fruitful discussions held at national meetings and forums. These guidelines are intended for endocrinologists and diabetologists, primary care physicians, cardiologists and other medical professionals involved in prevention and treatment of diabetes mellitus

Algorithms of Specialized Medical Care for Diabetes Mellitus Patients

Сахарный диабет (СД) ? системное заболевание обмена веществ, которое приняло пандемический характер распространения, что побудило Организацию Объединенных Наций (ООН) в декабре 2006 г. принять резолюцию, призывающую ?создавать национальные программы по предупреждению, лечению и профилактике СД и его осложнений и включать их в состав государственных программ по здравоохранению?. За последние 30 лет по темпам прироста заболеваемости СД опередил такие инфекционные заболевания, как туберкулез и ВИЧ. Численность больных СД в мире за эти годы выросла более чем в 2 раза и достигла к 2011г. 366 млн человек. В Российской Федерации, как и во всех странах мира, отмечаются высокие темпы роста заболеваемости СД. По данным Государственного регистра больных СД на январь 2011 г. в РФ по обращаемости в лечебные учреждения насчитывается 3,357 млн больных СД. Между тем результаты контрольно-эпидемиологических исследований, проведенных ФГБУ Эндокринологический научный центр (ЭНЦ) в период с 2002 по 2010 г., показали, что приблизительно еще 6 млн россиян имеют СД, но не знают об этом и, следовательно, не получают лечения. Самыми опасными последствиями глобальной эпидемии СД являются его системные сосудистые осложнения ? нефропатия, ретинопатия, поражение магистральных сосудов сердца, головного мозга, периферических сосудов нижних конечностей. Именно эти осложнения являются основной причиной инвалидизации и смертности больных СД. В РФ с 1996 г. осуществляется Федеральная целевая программа (ФЦП) ?Сахарный диабет? (с 2002 г. ? подпрограмма ФЦП ?Предупреждение и борьба с социально значимыми заболеваниями?), в рамках которой создана современная диабетологическая служба, позволившая осуществить реальный прорыв в диагностике, лечении, профилактике СД и его осложнений на территории РФ на основе внедрения современных диагностических систем, эффективных и безопасных лекарственных препаратов и средств самоконтроля, высокотехнологичных методов лечения сосудистых осложнений. Данное руководство ? ?Алгоритмы специализированной медицинской помощи больным сахарным диабетом? ? является пятым, обновленным и дополненным изданием. Руководство базируется на международном и отечественном опыте лечения СД, включая рекомендации Международной Диабетической Федерации (IDF 2005), Американской Диабетической Ассоциации (АDA 2011), Американской Ассоциации клинических эндокринологов (AACE, 2009), Международного общества по детскому и подростковому диабету (ISPAD, 2009), Российской ассоциации эндокринологов (РАЭ, 2011), а также результатах завершенных международных (ADVANCE, ACCORD, VADT, UKPDS и др.) и отечественных рандомизированных клинических испытаний у больных СД, в которых участвовали многие российские клиники. В новом издании Алгоритмов нашли отражение изменения, касающиеся диагностики СД, формулировки диагноза при СД, индивидуализации целевых значений гликемического контроля при СД 1 и 2 типа, стратегии сахароснижающей терапии при СД 2 типа, внесены уточнения по диагностике и лечению осложнений СД. Целью данного руководства является стандартизация и оптимизация оказания медицинской помощи больным СД во всех регионах России на основе доказательной медицины. Проект данного руководства неоднократно обсуждался на общероссийских конгрессах и форумах и получил одобрение абсолютного большинства специалистов. Рекомендации предназначены для эндокринологов и диабетологов, терапевтов, кардиологов, а также всех специалистов, принимающих участие в лечении больных СД

Standards of specialized diabetes care. Edited by Dedov II, Shestakova MV (6th edition)

Dear Colleagues!. We are glad to present the 6th Edition of Standards of Diabetes Care. These evidence-based guidelines were designed to standardize and facilitate diabetes care in all regions of the Russian Federation. The Standards are updated on the regular basis to incorporate new data and relevant recommendations from national and international clinical societies, including World Health Organization Guidelines (WHO, 2011), International Diabetes Federation (IDF, 2011), American Diabetes Association (ADA, 2013), American Association of Clinical Endocrinologists (AACE, 2009), International Society for Pediatric and Adolescent Diabetes (ISPAD, 2009) and Russian Association of Endocrinologists (RAE, 2011, 2012). Current edition of the ?Standards? also integrates results of completed randomized clinical trials (ADVANCE, ACCORD, VADT, UKPDS, etc.), as well as findings from the national studies of diabetes mellitus (DM), conducted in close partnership with a number of Russian hospitals. Latest data indicates that prevalence of DM increased during the last decade more than two-fold, reaching some 371 million patients by 2013. According to the current estimation by the International Diabetes Federation, every tenth inhabitant of the planet will be suffering from DM by 2030. These observations resulted in the UN Resolution 61/225 passed on 20.12.2006 that encouraged all Member States ?to develop national policies for the prevention, treatment and care of diabetes?. Like many other countries, Russian Federation experiences a sharp rise in the prevalence of DM. According to Russian State Diabetes Register, there are at least 3.799 million patients with DM in this country. However, the epidemiological survey conducted by the Federal Endocrinology Research Centre during 2002-2010 suggests that actual prevalence is 3 to 4 times greater than the officially recognized and, by this estimate, amounts to 9-10 million persons, comprising 7% of the national population. . Severe consequences of the global pandemics of DM include its vascular complications: nephropathy, retinopathy, coronary, cerebral and peripheral vascular disease. These conditions are responsible for the majority of cases of diabetes-related disability and death. . Current edition of the ?Standards? emphasizes the patient-oriented approach in making decisions on therapeutic goals, such as levels of glycaemia and blood pressure. It also features updated guidelines on the management of vascular complications and new RAE position statement on gestational diabetes, produced in collaboration with Russian Association of Obstetrics and Gynecology. . This text represents a consensus by the absolute majority of national experts, achieved through a number of fruitful discussions held at national meetings and forums. These guidelines are intended for endocrinologists and diabetologists, primary care physicians, cardiologists and other medical professionals involved in prevention and treatment of diabetes mellitus
