ABSTRACT
Several recent reviews have suggested a role of oxidative stress in the pathophysiology of COVID-19, but its interplay with disease severity has not been revealed yet. In the present study, we aimed to investigate the association between the severity of COVID-19 and oxidative stress parameters. Clinical data of 77 patients with COVID-19 admitted to the hospital were analyzed and divided into moderate (n = 44) and severe (n = 33) groups based on their clinical condition. Production of oxidant (hydrogen peroxide) and defense antioxidants (total antioxidant capacity, reduced and oxidized glutathione, glutathione s-transferase), and oxidative damage (malondialdehyde, carbonyl, and sulfhydryl) were assessed using the serum samples. The results revealed that severe patients who presented high serum leukocyte count and CRP level stayed for a longer period in the hospital. However, there was no correlation observed between the oxidative stress parameters and degree of COVID-19 severity in the present study. In conclusion, these results indicate that the disease severity may not be a detrimental factor contributing to the changes in the redox profile of hospitalized patients with COVID-19.
