Antiviral Treatment for COVID-19: A Systematic Review

Abstract

Aim: In December 2019, there were reports of a new type of coronavirus that affects the different health systems of the world. We have carried out a systematic review of the possible antivirals studied that could be useful in this public health catastrophe.
 Data Sources: A search strategy with MESH terms was performed in PubMed, Web of Science, and Scopus. Also, RCTs published in clinicaltrials.gov were reviewed. The databases were searched between April and June 2020.
 Study Selection: We selected all Randomized Controlled Trials evaluating the effects of antivirals and 5 studies were included from a research database of 280 articles collected between. After removing duplicated articles, 43 were selected for review. Finally, 5 articles were eligible for full-text review and included in the article.
 Results: Current randomized controlled trial data showed no clinical improvement in terms of mortality, need for oxygen support or need for intubation in patients who used antivirals versus those who did not. No clinical improvement was demonstrated. It was observed that there is difficulty in calculating clinical improvement, this large difference makes the eligible studies difficult to compare.
 Conclusion: These predictors, however, need further work to validate reliability. More clinical trials involving antivirals are needed to observe a relationship between clinical improvement or mortality from SARS-CoV-19.
