Abstract
Post-Covid syndrome is characterized by general somatic manifestations, changes in the psycho-emotional sphere, cognitive disorders, disorders of the cardiovascular, respiratory systems and excretory function. However, there is little information in the literature about the mechanisms of thanatogenesis in patients who have had COVID-19. An analysis of clinical and laboratory parameters and pathomorphological changes was carried out in 9 autopsy cases of patients who had previously suffered a new coronavirus infection (COVID-19). The age of the deceased ranged from 80 to 96 years. At the time of hospitalization, the concentration of IgG varied from 32.61 to 1013.5 RLU, IgM - from 0.29 to 16.98 U/ml. The period from clinical diagnosis to death ranged from 12 to 46 days, and the time from clinical recovery (negative polymerase chain reaction) to death ranged from 2 to 30 days. In all cases, unresolved viral pneumonia and diffuse alveolar damage (exudative-proliferative phase) were diagnosed.
