ABSTRACT
BACKGROUND: COVID-19, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has
caused a pandemic that has raised serious public health concerns. Medical health practitioners are
employing various treatment strategies that would have a potential to be effective in treating the
COVID-19. Hydroxychloroquine (HCQ) has been revealed to have significant effect on the replication
of SARS-CoV-2 virus in vitro. It has the antiviral characteristics in vitro that support the fact that this
drug has efficacy in the treatment of COVID-19. Based on this hypothesis, it is appropriate to use this
drug in clinical trials settings of preventing the COVID-19. OBJECTIVE: The main objective of this
study was to investigate the degree of corrected QT (QTc) and QT/QTc ratio interval prolongation in
patients with COVID-19 in association with their use of hydroxychloroquine (HCQ). RESULTS: In
this Randomized controlled trial (RCT) study, we have found that the patients who received
hydroxychloroquine (HCQ) for the treatment of COVID-19 were found to have no significant increase
in final/last QT/QTc ratio (p=0.680) comparing to initial QT/QTc ratio. CONCLUSION AND
RELEVANCE: In this study, patients who received HCQ for the treatment of COVID-19 were not
found to be at high risk of QTc prolongation. Clinicians should carefully determine the risk and benefits
of using HCQ with close monitoring of QTc changes.
