BACKGROUND. The clinical and epidemiological characteristics of diabetes mellitus (DM) and the quality of its therapy are the key prognostic dominant that determines the organizational aspects of the diabetic service. The continuous dynamic monitoring of DM has been carried out in the Russian Federation (RF) since 1996 through the activities of the Federal Register of Diabetes Mellitus (FDR).AIMS. The aim of our study was to analyze the epidemiological characteristics of DM in the RF (prevalence, morbidity, mortality), the prevalence diabetic of complications, the state of carbohydrate metabolism (level of HbA_1c) and the dynamics of the structure of glucose-lowering therapy (GLT) according to the FDR.MATERIALS AND METHODS. The database of FRD (https://www.diaregistry.ru/), 85 regions of the RF. The data are presented as of 01.01.2023 and in dynamics for the period 2010–2022.RESULTS. The total number of DM patients in the RF as of 01.01.2023 was 4 962 762 (3.31% of the population), including: Type 1 (T1) — 5.58% (277.1 ths), T2 — 92.33% (4.58 million), other DM types —2.08% (103 ths). The dynamics of prevalence over the 13-year period (2010→2022) was 146.0→191.0/100 ths people with T1, and 2036.2→3158.8/100 ths people with T2; morbidity in T1 12.3→8.2/100 ths population, in T2 260.1→191.4/100 ths population; мortality: T1 2.1→2.4/100 ths population, T2 41.2→86.1/100 ths of the population. The main cause of death was cardiovascular: in T1 38.6% cases, in T2 — 50.9%. Life expectancy (average age of death of patients): T1 was 52.7 years, the dynamics in males 50.9 → 50.7 years, females 62.1→56.0 years; in T2 — 74.2 years, males 69.5→70.4 years, females 74.2→76.1 years. The dynamic of DM duration from onset to the death: in T1 15.4→19.9 years; in T2 11→11.4 10.2→11.8 years. The proportion of patients with laboratory-measured HbA_1c <7% in the dynamics of 2010–2022: with DM1 24.4%→29%, with DM2 41.5%→42.2%, with HbA_1c ≥9.0%: with DM1 29, 4% → 20.4%, with DM2 13.8 → 9.0%.The incidence of diabetic complications as of 01.01.2023 in T1 and T2 patients: neuropathy 41.3% and 23.7%, nephropathy (CKD) 22.8% and 19.1%, retinopathy 28.9% and 12.3%, respectively. The structure GLT in T2 patients as of 01.01.2023: monotherapy — 41.6%; combination of 2 GLM — 30.0%, 3 GLM — 5.8%, insulin therapy in 18.3%.CONCLUSIONS. The information-analytical system FDR is a key tool for systematizing the most important epidemiological and clinical characteristics of DM based on data from real clinical practice, which allows optimizing the algorithm of patient management and improving the quality of care for diabetes.

BACKGROUND. One of the priority directions in the development of the health care system is to reduce the medical and social damage caused by the increase in the prevalence of diabetes mellitus (DM). From this point of view, the development of a diabetes register is very important as the main information and analytical platform for clinical and epidemiological monitoring of diabetes in the Russian Federation (RF).AIMS. The aim of our study was to analyze a dynamic (2016–2020) of the epidemiological characteristics of diabetes mellitus in the Russian Federation (prevalence, morbidity, mortality), the prevalence of complications, the level of HbA_1c and the dynamics of the structure of glucose-lowering therapy (GLT) according to the Federal Diabetes Register (FDR).MATERIALS AND METHODs. The database of FRD (http://diaregistry.ru) 84 regions of the RF. The data are presented in dynamics 2016→2020.RESULTS. The total number of DM patients in the RF as of 01.01.2021 was 4,799,552 (3.23% of the population), including: Type 1 (T1) — 5.5% (265.4 ths) , T2 — 92.5% (4.43 million), other DM types — 2.0% (99.3 ths). The dynamics of prevalence was 168.7→180.9/100 ths people with T1, and 2709 → 3022/100 ths people with T2; morbidity in T1 10.5→7.7/100 ths population, in T2 219.6→154.2/100 ths population. Age and sex characteristics: the proportion of men in T1 — 54%, in T2 — 30%; the max proportion of patients with T1 at the age of 30–39 years, T2 65–69 years. Mortality: T1 3.0 → 2.7/100 ths population, T2 87.7→93.9/100 ths of the population, the main cause of death was cardiovascular: in T1 38,1% cases, in T2 — 52,0%. Life expectancy (average age of death of patients): T1 was 53.2years, the dynamics in males 50.7 → 50.5years, ­females 58.7→55.2years; in T2 — 73.5 years, males 70.2→70.1years, females 75.7→75.4 years. The dynamic of DM duration until the death: in T1 17.4→19.0 years; in T2 11→11.4 years. The incidence of diabetic complications in T1 and T2 patients: neuropathy 43.3% and 24.4%, nephropathy (CKD) 25.9% and 18.4%, retinopathy 31.7% and 13.5%, respectively. The ­proportion of ­patients with HbA_1c <7%: in T1 32.3%→36.9%, in T2 51.9%→52.1%, with HbA1c ≥ 9.0% in T1 23.1%→18.7% , in T2 8.9%→8.0%. The structure GLT in T2 patients: glucose lowering medications (GLM) — 76.2% (monotherapy — 44.1%; ­combination of 2 GLM — 28.9%, 3 GLM — 3.2%), insulin therapy in 18,8%, without drug therapy in 4.9%.CONCLUSIONS. The performed analysis demonstrates the importance of dynamic assessment of epidemiological characteristics and monitoring of clinical data on patients with diabetes through a registry for assessing the quality of diabetes care and the prospects for its development.

BACKGROUND: The enormous social lesion caused by high prevalence of diabetes mellitus (DM) determines the state importance of clinical and epidemiological monitoring organization. AIMS: To analyze epidemiological characteristics (prevalence, mortality, morbidity), the level ofHbA1c, evaluate the therapy in Russian Federation in 20132017. METHODS: We have used the database of the Russian Federal Diabetes register 81 regions included in the online register system. RESULTS: The total number of patients with DM was 4,498m. (3.06% RF population), including: Type 1 (T1) 5,7% (0,26 m), T2 92,1% (4,15m), other DM types 1,9% (83,8 ths). Distribution male/female: T1 53.5%/46.5%, T2 29%/71%, other DM types 24%/76%. The proportion of men decreases with aging. Number of patients 65 years was 2.293.520, including T1 21.97ths (3.6%), T2 2m271.5ths (54.7%). The prevalence 20132017 per 100,000 population was as follows: T1 159,8169,6; T2 2455.32775.6; other DM types 51,265,8. Morbidity: T1 9,87,0; T2 226,7185,2; other DM types 7,812,4. The structure of causes of death 20132017: T1: diabetic coma 2,01,5%, myocardial infarction 4,04,4%, cerebral circulation disorders 8,27,6%, cardiovascular insufficiency 18,516,4%, chronic renal failure 6,16,0%; T2 0,20,2%, 4,54,5%, 12,712,2%, 29,028,6%, 1,21,8%, respectively. Mortality: T1 2.3; T2 68.4, other DM types 0,8. Life expectancy (average age of death of patients): T1 male 50.350.2, female 60.257.2; T2 69.870.3, 75.175.9 respectively. The number of patients with targetHbA1clevel 7%: T1 22.334.0%, T2 38.052.4%;HbA1c9.0%: T1 29.221.1%, T2 12.68.8%. The most commonly prescribed classes of glucose lowering medications (GLM) in 2017: in monotherapy Metformin (57.3%), Sulfonilurea (SU) (41,1%); in combination of 2 GLM: Metformin+SU 92,58% Metformin+iDPP-4 5.63%; 3 or more GLM: Metformin+SU+iDPP-4 83,9%, Metformin+SU+iSGLT-2 8.98%. The proportion of patients on aGPP-1 therapy is 0.01%. CONCLUSIONS: We observed the growth of prevalence of DM in Russian Federation and decrease in registered morbidity rate; an increase in life expectancy in T2; decrease in mortality due to diabetic coms and stable mortality rate from cardiovascular events (heart attack, stroke, cv deficiency), gangrene, chronic renal failure in both types of DM; a steady improvement in glycemic control. In the structure of T2 therapy the oral GLMs are dominated, especially Metformin and SU. In the dynamics the prescription of Metformin, insulin, iDPP-4, iSGLT-2 has increased, the proportion of SU has decreased.

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 <7% in 2018, with T2DM – 52.2%. There is a decrease in prevalence of complications in T1/T2 patients compare with 2007 year: ketoacidotic coma in 3/4 times, blindness in 2/4.4, diabetic foot syndrome in 1.5/3 times, respectively. Detailed analysis of DM complications became available after NDR was transferred to the online format (for the period since 2013). The article presents data of the prevalence of diabetic retinopathy and blindness, chronic kidney disease, diabetic foot syndrome, amputations and cardiovascular complications in DM patients. Conclusions. Despite the continued increase in the number of DM patients, significant achievements have been made in the management of DM in RF over the past decade. There is a significant improvement in the quality of diagnosis of complications and decrease in its frequency. The priority remains the development of specialized diabetes care at all levels from primary care to regional centers, as well as standardization of screening algorithms and early diagnosis methods.

The Federal Diabetes Register (FDR) has been conducting clinical and epidemiological monitoring of diabetes in the Russian Federation (RF) since 1996. Its methodological and organizational reference centre is Endocrinology Research Centre. FRD was created by Order of the Ministry of Health of RF №404 of December 10, 1996 as part of implementation of the Federal target program "Diabetes Mellitus". Over the 20-year period, the registry has played a key role in assessing the prevalence of diabetes and diabetic complications in the RF. Since 2014, the register has been transformed into online system as a unified federal database with an authorized code access. Personal data protection is carried out in accordance with the laws and regulations of the Russian Federation.
