American scientists have concluded that the anti-malarial hydroxychloroquine used in the treatment of Covid-19 increases the risk of death among patients. This is stated in the results of a study published by the medical journal The Lancet, as CNBC reports.
"Hospitalized patients with Covid-19 who were treated with antimalarial hydroxychloroquine were at a higher risk of death than those who did not take it," the study said.
Such data was obtained by scientists from Harvard Medical School, Brigham and Women's Hospital and other medical institutions. Researchers observed patients who were hospitalized with Covid-19 between December 20 and April 14. 14 thousand 888 patients received hydroxychloroquine or chloroquine, alone or in combination with macrolide. The remaining 81,144 patients were in the control group.
About 10,700 patients died in the hospital. The study involved more than 96,000 patients from 671 hospitals on six continents.
After taking into account many factors, including age, race, gender and basic health conditions, the risk of mortality among patients taking hydroxychloroquine increased by 34%, and the risk of serious heart arrhythmia - by 137%.
The results of the experiment were released a few days after US President Donald Trump announced the daily use of hydroxychloroquine for the prevention of coronavirus. The president has been taking the drug for more than a week, contrary to warnings from the US Food and Drug Administration.
White House doctor Dr. Sean Conley published a note on Monday stating that after discussing the pros and cons of hydroxychloroquine, he and Trump came to the conclusion that the potential benefit of the drug over the relative risks of using it.
In addition to treating malaria, hydroxychloroquine is also often used by doctors to treat rheumatoid arthritis and lupus. The medicine has serious side effects, including muscle weakness and cardiac arrhythmia.
As we reported before, the epicenter of the global pandemic of the coronavirus Covid-19 has moved to South America six months after it appeared on the other side of the world in Wuhan, China.
