Pathogenetic syndrome management of a patient with COVID-19

Abstract

Background. In case of coronavirus pneumonia, the virus damages the cells of bronchi and alveoli, as well as triggers a powerful inflammatory response that disrupts the surfactant and prevents the adequate oxygenation. These pathogenetic links lead to the development of acute respiratory distress syndrome, multiorgan hypoxia and disseminated intravascular coagulation syndrome. Objective. To find out the main pathogenetic links that can be affected by coronavirus disease (COVID-19) treatment. Materials and methods. Analysis of literature sources on this topic. Results and discussion. Hypoxia is one of the main backgrounds of coronavirus organ damage in COVID-19. The consequences of hypoxia include the imbalance between aerobic and anaerobic glycolysis, increased lipid peroxidation, acidosis, microcirculation disorders, edema. Pathologically active inflammation is another background. It leads to the damage of pulmonary capillaries, microcirculation disorders and the development of acute respiratory distress syndrome with increased hypoxia. Since the reactive oxygen species are the main inducers of apoptosis and mitochondrial dysfunction, it is necessary to prescribe antioxidant therapy. Edaravone (Ksavron, “Yuria-Pharm”) quickly neutralizes lots of free radicals, inhibits lipid peroxidation and activates the own antioxidant defense. Other components of the pathogenetic therapy of COVID-19 may include Tivortin and Tivorel (“Yuria-Pharm”). L-arginine (Tivortin) is a nitric oxide donor. Its administration has vasodilating, immunostimulating, membrane stabilizing, cytoprotective and antioxidant effects. Tivorel also contains L-carnitine, which inhibits apoptosis, has antioxidant and cardioprotective effects. In case of pneumonia, it is advisable to use Reosorbilact (“Yuria-Pharm”), which prevents pulmonary edema and restores microcirculation. Conclusions. 1. Hypoxia and hyperinflammation are the main elements of the COVID-19 pathogenesis. 2. Edaravone (Ksavron) neutralizes free radicals and activates own antioxidant defense. 3. L-arginine (a component of Tivortin and Tivorel) has vasodilating, immunostimulating, membrane stabilizing, cytoprotective and antioxidant effects. 4. Reosorbilact prevents pulmonary edema and restores microcirculation.
