The effectiveness of chloroquine questioned for treating Covid-19

A study in the United States of nearly 1,400 patients found that hydroxychloroquine had little or no effect on the coronavirus.

Results which seem to contradict the intuitions of certain scientists, including the very media Didier Raoult. According to a new study carried out in two hospitals in New York (United States), hydroxychloroquine has a very limited, if not almost nonexistent, effect on SARS-CoV-2, the virus responsible for the Covid-19 pandemic.

No less than 1,376 patients made up the sample for this large-scale test, funded by the service of the United States National Institutes of Health (NIH). 811 of them underwent treatment with hydroxychloroquine (two doses of 600 mg the first day, then 400 mg per day for four days), while the other 565 were not treated with the famous molecule.

No improvement or deterioration of the patient’s condition

The results of this experiment revealed a clear trend, as Nice Matin explains: “the administration of hydroxychloroquine did not significantly improve or deteriorate the condition of seriously ill patients with Covid-19, compared to patients who have received nothing ”.

This study therefore did not allow significant progress to be made in the search for an effective treatment. Its authors do not wish to completely exclude hydroxychloroquine from potential protocols. “However, our results do not support its use at the moment, apart from randomized clinical trials (where the patients are randomly distributed, editor’s note) in order to demonstrate its effectiveness”, specify the American scientists, quoted by Nice Matin.
