Quote: Chloroquine and hydroxychloroquine By Live Science Staff 6 days ago:- Chloroquine and hydroxychloroquine have been approved by the U.S. Food and Drug Administration for the treatment of malaria, lupus and rheumatoid arthritis, but preliminary research in human and primate cells suggests that the drugs could effectively treat COVID-19. A 2005 study found that chloroquine could quell the spread of SARS-CoV when applied to infected human cells in culture. SARS-CoV is closely related to the novel coronavirus, SARS-CoV-2, and caused an outbreak of severe acute respiratory syndrome in 2002. Chloroquine disrupts the ability of the SARS-CoV virus to enter and replicate in human cells, Live Science previously reported. The cell culture studies of SARS-CoV-2 revealed that the drug and its derivative hydroxychloroquine undermine the novel virus' replication in a similar way. Doctors in China, South Korea, France and the U.S. are now giving the drug to some patients with COVID-19 with promising, albeit anecdotal, results so far. The FDA is organizing a formal clinical trial of the drug. As of Feb. 23, seven clinical trials had been registered in the Chinese Clinical Trial Registry to test whether COVID-19 infections could be treated with hydroxychloroquine. In addition, the University of Minnesota is studying whether taking hydroxychloroquine can protect people living with infected COVID-19 patients from catching the virus themselves. In one heavily referenced study, conducted in France, a small number of patients with COVID-19 received either hydroxychloroquine alone or hydroxychloroquine in combination with an antibiotic called azithromycin. The authors reported that detectable concentrations of SARS-CoV-2 fell significantly faster in the study participants than coronavirus patients at other French hospitals who did not receive either drug. In six patients also given azithromycin, this promising effect appeared to be amplified. However, the CDC noted that the small, non-randomized study "did not assess clinical benefit[s]" associated with the treatment; in other words, the study did not probe whether the treated patients were more likely to recover and survive their illness. Additionally, the agency advised that doctors should be cautious when giving either drug to patients with chronic disease, such as kidney failure, and especially those "who are receiving medications that might interact to cause arrhythmias." *** By Live Science Staff 6 days ago *** By Live Science Staff 6 days ago
