Abstract

Background: It is known that an inflammatory response plays a key role in COVID-19 pathogenesis. An exacerbated inflammatory response can increase oxidative stress in cells. This study aimed to investigate the effects of COVID-19 on parameters of oxidative stress including non-protein thiol antioxidants (NPSH), protein thiols (PSH), total antioxidant capacity (TAC), advanced oxidation protein products (AOPP), myeloperoxidase (MPO), thiobarbituric acid reactive substances (TBARS), ascorbic acid, and reactive oxygen species (ROS) in plasma collected four to six weeks after the diagnosis.

Methods: This cross-sectional study included a sex-matched sample of 296 adult individuals with 112 positives (cases) and 184 negatives (controls) for COVID-19. Oxidative stress parameters were peripherally analyzed according to previous methods.

Results: The results showed a decrease in NPSH (p = 0.004), TAC (p = 0.005), ROS (p < 0.001), and ascorbic acid (p < 0.001) in cases. TBARS were higher in moderate and severe cases of COVID-19 compared to asymptomatic and mild cases (p = 0.049). AOPP, PSH, and MPO were not significantly different between cases and controls. In the total sample, individuals who self-reported using medication to prevent or treat COVID-19 showed decreased NPSH (p = 0.034), TAC (p = 0.020), ascorbic acid (p = 0.010), and ROS (p = 0.001) compared to those who self-reported not using medication to prevent or treat COVID-19.

Conclusions: In conclusion, individuals with COVID-19 had decreased antioxidant status. Furthermore, disease severity was associated with more lipid damage. Antioxidant therapies may be essential to prevent the impacts of COVID-19.

期刊介绍： Pharmacological Reports publishes articles concerning all aspects of pharmacology, dealing with the action of drugs at a cellular and molecular level, and papers on the relationship between molecular structure and biological activity as well as reports on compounds with well-defined chemical structures. Pharmacological Reports is an open forum to disseminate recent developments in: pharmacology, behavioural brain research, evidence-based complementary biochemical pharmacology, medicinal chemistry and biochemistry, drug discovery, neuro-psychopharmacology and biological psychiatry, neuroscience and neuropharmacology, cellular and molecular neuroscience, molecular biology, cell biology, toxicology. Studies of plant extracts are not suitable for Pharmacological Reports.
