AIM: To assess the prevalence of chronic kidney disease (CKD), clinical and demographic characteristics and therapy profile in patients with type 2 diabetes admitted to multidisciplinary hospitals. CREDO (Cardio-REnal Diabetic cOmplications) trial was initiated for this purpose.MATERIALS AND METHODS: in a prospective observational multicenter study for the period from August 2022 to April 2023, data from 445 patients with type 2 diabetes hospitalized in multidisciplinary hospitals of the Moscow Department of Health were analyzed. The data was collected on a single visit. The design of the study did not involve any interventions in routine clinical practice, including the choice of a diagnostic or treatment method.RESULTS. The study included 445 patients with the main inclusion criteria — type 2 diabetes, age over 50 years, duration of diabetes more than 3 years. The prevalence of CKD was 90%, while in 43% the diagnosis of CKD was confirmed, in 43% it was detected for the first time, and in 7% the disease progressed. Patients with stage C2 and C3 (a and b), as well as with levels of A1 and A2 albuminuria, were most often identified. The percentage of patients in whom the albuminuria was not performed remained high — 46.2%. The highest incidence of CKD was observed in patients with inadequate glycemic control, having an HbA1c level of ≥9%. In the group with newly diagnosed CKD, sodium-glucose co-transporter-2 inhibitor (iSGLT-2) was received by 31.1% of patients, glucagon-like peptide-1 receptor agonists (GLP-1 RA) — 7.9% of patients. In the group with confirmed CKD — 30.7% and 9.4%, respectively.CONCLUSION: it has been shown that patients over the age of 50 with type 2 diabetes with a disease duration of more than 3 years are at a high risk of developing CKD — 90%. The results obtained convincingly confirm the possibility of detecting CKD and initiating nephroprotective therapy at the hospital stage.
