Current concepts on immunopathology of COVID-19 and emerging therapies

Abstract

Context: This scoping review tries to synthesize early findings on the immunopathogenicity of SARS-CoV-2 to assess the emerging therapies and vaccines by evaluating their impact based on the mechanism of pathogenicity. Methods: The three databases of PubMed, Scopus, and Google Scholar were searched from January 1, 2020, to March 15, 2020. To extract the results from the studies, the content, thematic analysis method was used. In this method, the topics studied were coded in the articles, and then major topics related to the articles were determined. After identifying major issues, the contents of the articles were reviewed. Results: A total of 2,250 articles were retrieved after deleting duplications, and after reviewing the thematic relevance, 45 of them were selected for the final analysis. Topics studied in the articles were classified into four main areas, including “virus entry inhibi-tion and immune response”, “vaccine and treatment targets”, “genome structure similarity to other coronaviruses,” and “pathogen-sis”. Conclusions: Results of this review showed that we have a long way to develop an effective and safe vaccine due to the structural and behavioral complexities of this virus. In the meantime, the scientific community should use results of megatrials, but until their accomplishing them, we have to use results of systematic reviews of randomized controlled trials.
