Hydroxychloroquine Or chloroquine in Covid-19: systematic review of systematic reviews

Abstract

Many of the known coronaviruses cause a wide range of respiratory infections in humans, and the novel coronavirus is no exception to this rule. Although no drug has yet been discovered to prevent or treat this disease, chloroquine (CQ) and hydroxychloroquine (HCQ) have been widely used in studies showing different results.

Methods: The present study is an umbrella study. The search was conducted for the articles published from January 2020 to November 2020 using the keywords (“COVID-19” OR “SARSCoV-2” AND “Hydroxychloroquine “OR “Chloroquine” AND “Systematic Review” OR “Metanalysis”). This study was limited to human samples and systematic reviews with or without meta-analysis. The quality of the articles was also evaluated independently by two researchers.

Results: To evaluate the clinical efficacy of HCQ and CQ, a total of 176 papers and 643569 cases ranging from patients with mild pneumonia to intubated critically ill patients were evaluated. Finally, 8 studies were included.
