Diabetes mellitus type 1 in children and adolescents in Moscow. Data from the Moscow Segment of the Federal Register of Diabetic Patients 2015-2020.

BACKGROUND: Therapy for type 1 diabetes mellitus (T1DM) is still largely an unsolved clinical problem. Despite the introduction into clinical practice of modern insulin preparations, devices for its administration, as well as continuous monitoring of glucose levels, the goals of therapy are often not achieved. At the same time, the International Diabetes Federation (IDF) notes an increase in the prevalence and incidence of T1DM in children and adolescents in the world. The Federal Register of Diabetes Mellitus (FRDM) is a dynamically updated database of patients with diabetes, which allows assessing prevalence and incidence rates, achievement of glycemic control goals and the incidence of diabetes complications. AIM: analyze the epidemiological data of T1DM (prevalence, morbidity) in children and adolescents (patients from birth to 18 years of age) in Moscow according to the FRSD data and to assess their dynamics, as well as the dynamics of achieving the goals of glycemic control and the incidence of T1DM complications in 2015-2020. MATERIALS AND METHODS: The object of the study is a sample from the database of the Moscow segment of the FRDM of a cohort of patients with type 1 diabetes under 18 years of age who were registered for the period 01.01.2015-01.01.2021. Epidemiological prevalence and incidence rates are calculated per 100,000 of the relevant population. RESULTS: the number of children and adolescents with type 1 diabetes in Moscow as of 01.01.2021 was 4024 people (2962 children and 1062 adolescents). Over the period from 2015 to 2020, there was an increase in the prevalence of T1DM (possibly due to an increase in the quality of data registration in the FRSD) and a decrease in the incidence of both children and adolescents. There was also a decrease in the level of HbA1c and the proportion of patients with HbAc1> 8.0% among children with T1DM. Both children and adolescents with T1DM showed a decrease in the incidence of diabetic coma and ketoacidosis with a simultaneous increase in the incidence of severe hypoglycemia, as well as a decrease in the incidence of retinopathy and nephropathy. However, the incidence of neuropathy decreased among children and increased among adolescents. CONCLUSION: The data obtained on the dynamic management of adolescents with T1DM are the basis for considering the development of a profile program for their dynamic observation, taking into account the need for psychological and social support for patients and their families.

[Resolution on the results of the first working meeting of the Scientific Advisory Board «Actual problems of glycemic variability as a new criterion of glycemic control and safety of diabetes therapy¼].

June 19, 2018 the meeting of the Scientific Advisory Board took place in Moscow, chaired by Professor G.R. Galstyan, (co-chair - A.V. Zilov) devoted to the discussion of the possibilities of improving the results of treatment of diabetes mellitus (DM) by consideration of «variability of glycemia¼ (VG) as an additional criterion of the glycemic control effectiveness (especially of insulin therapy) as well as one of the goals of treatment in patients with unstable glycemia. The purpose of the working meeting was to develop a strategy for the introduction of VG as a predictor and an additional criterion in assessing the effectiveness and safety of hypoglycemic therapy to improve the pharmacotherapy of diabetes and reduce cardiovascular and total mortality. Aims: - to conduct a comprehensive data analysis of the relationship between VG and adverse DM outcomes, such as hypoglycemia, micro-and macrovascular complications, cardiovascular and total mortality; - to accumulate and analyze published data and the experience of decrease of VG and improving outcomes of diabetes on the background of different versions of insulin therapy; - to compare existing methods of glycaemia monitoring and VG assessment, their validity and availability in real practice in the context of limited budget; - to analyze the informativeness, clinical and prognostic significance of various parameters of VG assessment and determine their reasonable «minimum¼ for a comprehensive assessment of VG as a criterion for evaluating the effectiveness of treatment of DM and predictors of negative diabetes outcomes. The following reports were heard during the discussion: Glycemic variability: clinical and prognostic value. Types of glycemic variability. (Alexey V. Zilov, MD, PhD in Medicine, Assistant Professor). Methods of assessment of variability of glycemia in clinical trials and routine practice (Tatiana N. Markova, MD, PhD in Medicine, Professor). Current international and national recommendations on glycemic monitoring (Gagik R. Galstyan, MD, PhD in Medicine, Professor).
