Zinc pathogenic importance in correcting immunity and restoring public health in the post-COVID period: An overview

Abstract

Context: The problem of correcting immune system function and compensating for co-morbidities becomes particularly clinically significant in the post-COVID period. There is evidence that certain trace elements in the human body, particularly zinc ions, play a critical role in restoring the function of the immune system and internal organs. Objective: To analyze the mechanisms of zinc action maintaining the body homeostasis in order to justify pathogenetically the inclusion of zinc drugs in the therapy of patients in the post-COVID period. Methods: Data from Elsevier, Global Health, PubMed-NCBI, Embase, MEDLINE, Scopus, Research gate, RSCI Scopus, Cochrane Library, Google Academy, e-LIBRARY.RU and CyberLeninka were used. Results: This review showed that the importance of zinc in maintaining body homeostasis in the post-COVID period is determined by its multifaceted effect on all parts of the immune system, its anti-inflammatory activity, antimicrobial properties and participation in the restoration of internal organ function. Elimination of zinc deficiency in the post-COVID period is essential to support immunity, compensate for comorbidities and reduce the risk of complications. The impossibility of synthesizing zinc in the body requires its constant intake in sufficient quantities. Zinc levels are significantly reduced after infectious diseases, as this element is specifically distributed to organs and tissues to maintain immunological and metabolic functions. The degree of zinc deficiency is associated with the severity of COVID-19 and the post-COVID period. It is pathogenetically justified to prescribe zinc drugs in the post-COVID period, the choice of which should take into account comorbidities and severity of hypozincemia. Conclusion: Regularly administered therapy with zinc drugs in the post-COVID period will help correct the population immunity and restore public health.
