Comprehensive Literature Review and Evidence evaluation of Experimental Treatment in COVID 19 Contagion.

ABSTRACT

IMPORTANCE Coronavirus 2019 pandemic (COVID 19) is caused by the Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) virus. The pandemic is affecting the livelihood of millions of people all over the world. At the time of preparing this report, the pandemic has affected 1 827 284 patients, with 113 031 deaths in 185 countries as per Johns Hopkins University. With no proven treatment for the disease, prevention of the disease in the community and healthcare setting is need of the hour. OBJECTIVE: To perform a comprehensive literature search for preventive measures and experimental treatment options. In this review, we have focused our discussion on the risk of disease transmission, supportive treatment, and possible treatment options based on available evidence. EVIDENCE REVIEW We performed a literature search on google scholar, PubMed, and society guidelines for literature related to COVID 19 and previous coronavirus pandemics. We included data review articles, observational studies, and controlled trials to synthesize the treatment options for COVID 19. FINDINGS: In this article, we have extensively reviewed and discussed recommendations from various world organizations for the public and healthcare workers. We have also discussed currently available experimental treatments since there is no proven treatment for COVID 19. The best method of dealing with the current outbreak is to reduce the community spread and thus "flatten the curve." Although Hydroxychloroquine, Remdesivir, Lopinavir/Ritonavir, and Azithromycin have been tried, passive immunity through convalescent serum and vaccine is still at an experimental stage. Patients with severe COVID 19 infections could be considered for this experimental treatment through various national randomized control trials, which may eventually lead to an evidence-based treatment strategy. CONCLUSIONS AND RELEVANCE Awareness of currently available experimental treatment among healthcare providers and exploration of possible treatment options through evidence is need of the hour. We have discussed the most recently available literature and evidence behind experimental treatment in this article.
