NO IMPROVEMENT IN DEATH RATE FOR COVID-19 PATIENTS WHO RECEIVED HYDROXY CHLOROQUINE

A research team led by investigators from Brigham and Women’s Hospital has evaluated real-world evidence related to outcomes for COVID-19 patients who were treated with hydroxychloroquine or chloroquine analogues (with or without a macrolide). Investigators found no evidence that either drug regimen reduced the death rate among patients. Patients treated with hydroxychloroquine or chloroquine regimens were far more likely to experience abnormal, rapid heart rhythms (known as ventricular arrhythmias) than their counterparts who had not received the drugs. The team’s findings are published in The Lancet.

“No matter which way you examine the data, use of these drug regimens did not help,” said corresponding author Mandeep R. Mehra, MD, executive director of the Brigham’s Center for Advanced Heart Disease. “If anything, patients had a higher likelihood of death. We also saw a quadrupling in the rate of significant ventricular arrhythmias in patients with COVID-19 who had been treated with hydroxychloroquine or chloroquine regimens.” #COVID19
