In the largest observational study thus far investigating the drug hydroxychloroquine
as a treatment for COVID-19, researchers found little evidence that it
helps, and worrying evidence that the medication may cause harm.
In a study published May 22 in the journal Lancet,
scientists in the U.S. and Switzerland report on an analysis of more
than 96,000 people hospitalized with confirmed COVID-19 in 671 hospitals
on six continents. Nearly 15,000 patients were treated with one of the
following: chloroquine (which is an older version of
hydroxychloroquine), hydroxychloroquine, or either of those drugs in
combination
People in any of the four treatment groups were more likely to die
during their hospitalization than those not treated. People receiving
either chloroquine or hydroxychloroquine alone were 16% to 18% more
likely to die in the hospital compared to those not receiving the
medications, and those treated with these medications in combination
with an antibiotic were 22% to 24% more likely to die in the hospital.
These risks remained significant even after the researchers controlled
for factors such as smoking, underlying heart disease, diabetes, lung
disease, or immune conditions.
with an antibiotic. The remainder did not receive any of
these medications and served as the control.
