New analysis shows hydroxychloroquine does not lower mortality in COVID-19 patients, and is associated with increased mortality when combined with the antibiotic azithromycin.
“This meta-analysis shows that hydroxychloroquine alone is not effective for the treatment of COVID-19 patients and that the combination of hydroxychloroquine and azithromycin increases the risk of mortality,” say the authors who include Thibault Fiolet, Center for Research in Epidemiology and Population Health, INSERM, Institut Gustave Roussy and Paris-Sud 11 University/Paris-Saclay University, Paris, France. “These data support current clinical recommendations such as those of the US National Institutes of Health (NIH) which do not recommend the use of hydroxychloroquine alone or in combination with azithromycin for COVID-19 patients.”
The authors conclude
“There is already a great number of studies that have evaluated hydroxychloroquine alone or in combination and it seems unlikely at this stage that any efficacy will ever emerge. Our results suggest that there is no need for further studies evaluating these molecules, and the European DisCoveRy and WHO international Solidarity clinical trials have already discontinued treatment arms using hydroxychloroquine.”
