Psychosomatic state and laboratory parameters of COVID-19 convalescent patients.

ABSTRACT

Objective. To evaluate some parameters of the psychosomatic state, cytokine levels (IL-6, IL-8, IL-17A), and free radical status (levels of nitrates and nitrites, antioxidant plasma activity) in convalescent patients after severe COVID-19. Patients and methods. We examined 64 patients who had severe COVID-19 and underwent either a 30-35-day course of inpatient rehabilitation after their discharge from a hospital for infectious diseases or a 60-65-day course of outpatient rehabilitation at the Ambulatory Center of Nalchik, Clinical Hospital No 1. Results. We surveyed patients after severe COVID-19 and found that they required a long rehabilitation. Many of them reported asthenic syndrome, psycho-emotional disorders, and other complaints upon discharge from the hospital. Serum levels of proinflammatory cytokines remained high in patients after severe COVID-19 even 30-35 days following their discharge (p < 0.05). Serum levels of IL-6, IL-8, nitrites, and nitrates remained elevated on days 60-65 following discharge (p < 0.05), despite comprehensive therapy in a rehabilitation department. Plasma antioxidant activity was reduced, whereas IL-17A level normalized by this time. Conclusion. Our findings suggest that currently used rehabilitation measures for COVID-19 are insufficient. Adequate rehabilitation of convalescent COVID-19 patients requires proper monitoring of their immune system condition, as well as new effective methods for immune correction and restoration of their psychoemotional status after the acute phase of the disease.Copyright © 2022, Dynasty Publishing House.
