Abstract

Objective: to study changes in innate and adaptive immunity in patients with a moderate course of COVID-19 with varying degrees of lung tissue damage. 40 patients with a moderate form of COVID-19 and varying degrees of damage to the lung tissue (up to 25% and up to 50%) and 30 patients from the control group (healthy donors) were examined using methods: computed tomography of the lungs, evaluation of a complete blood count, biochemical parameters, immunological studies, statistical. Differences in all patients with the control group consisted in a decrease in the absolute content of lymphocytes, in a significant increase in the relative content of natural killers and cytokine imbalance. The most significant differences were registered in the content of IL-6, depending on the degree of damage to the lung tissue. A smaller area of lung damage reflects a milder course of the disease, which does not exclude the need for dispensary observation and rehabilitation after discharge.
