ABSTRACT
Kidney disease and chronic renal failure are among the main comorbidities of the complicated course of COVID-19. Objective: to identify the clinical features of the course of a new coronavirus SARS-CoV-2-infection in a child aged 2 years 2 months with chronic kidney disease and dialysis-dependent renal failure. A new coronavirus infection typically began with a moderate intoxication syndrome and catarrhal symptoms, confirmed by the detection of SARS-CoV-2 RNA. Computed tomography of the chest revealed signs of bilateral pneumonia, 30% damage to the lung tissue. Progression occurred by the 4th day of hospitalization with the development of a multisystem inflammatory syndrome, including damage to the cardiovascular system of the digestive system against the background of the existing end-stage renal failure. Laboratory criteria for multisystem inflammatory syndrome were an increase procalcitonin, C-reactive protein, and ferritin. As a result of the developed multiple organ failure, a fatal outcome occurred.
