Brazil President Embraces Unproven ‘Cure’ as Pandemic Surges

RIO DE JANEIRO — The coronavirus was taking root in Latin America when President Jair Bolsonaro of Brazil startled the medical community with a claim: A miracle drug was on hand.

“God is Brazilian, the cure is right here!” the president exclaimed in late March to a throng of supporters. “Chloroquine is working everywhere.”

Since then, the virus has ripped through Brazil. More than 41,000 people have died — Brazil has now passed Britain and has recorded more fatalities than any country other than the United States — and the daily death toll is now the highest in the world, bucking the downward trend that is allowing other major economies to reopen.

Mr. Bolsonaro ordered the armed forces to mass produce it in the military’s pharmaceutical laboratory and ordered a large supply of the drug’s ingredients from India.

“Decisions are being made not based on evidence and empirical data but rather on anecdotal reports,” said Denise Garrett, a Brazilian-American epidemiologist who worked at the Centers for Disease Control and Prevention for more than 20 years. “Bolsonaro invested a huge amount of money into an action that has not been proven to be effective at the expense of increasing testing and contact tracing.”

Between February, when Brazil identified its first coronavirus case, and June, when Brazil’s coronavirus caseload topped 828,000, lagging only behind the United States, the country had months to learn from other nations that had been ravaged by the virus and prepare for the pandemic.

Instead, Mr. Bolsonaro has led the country down what health experts call a perilous path: He sabotaged quarantine measures adopted by governors, encouraged mass rallies and repeatedly dismissed the danger of the virus, asserting that it was a “measly cold” and that people with “athletic backgrounds,” like himself, were impervious to serious complications.

Under his tenure, decisions about medical and scientific protocols became measures of political loyalty. As the coronavirus crisis worsened, Mr. Bolsonaro leaned on the health ministry to embrace widespread use of chloroquine and hydroxychloroquine, straining his relationship with the two physicians who have served as health ministers. One was fired in April and the other one lasted less than a month on the job.

Their successor, an active duty general with no medical experience, agreed to issue guidance encouraging doctors to prescribe the drug widely for Covid-19 patients.

Chloroquine and Hydroxychloroquine are both anti-malaria drugs but they have distinct secondary uses; hydroxychloroquine also treats lupus and rheumatoid arthritis. Both drugs are among the pharmaceuticals being studied as potential remedies for Covid-19, but neither drug has been approved as a reliable treatment for Covid-19 patients.

The United States Food and Drug Administration warned against use of the two drugs in Covid-19 patients outside of hospital settings because they can cause heart problems.

Margareth Dalcolmo, a prominent pulmonologist and researcher at Fiocruz, a government agency that does health care research in Rio de Janeiro, said Brazil’s embrace of the drug set a dangerous precedent — and is hampering the necessary research.

The controversy over hydroxychloroquine has also reverberated outside Brazil.

In mid-May, President Trump said he had begun taking the drug as a preventive measure, which generated consternation among doctors.

Later that month, the White House announced it was donating two million doses of the drug to Brazil so it could be used “to treat Brazilians who become infected.”

Representative Eliot Engel, the New York Democrat who chairs the House Foreign Affairs Committee, called that decision appalling. “It’s irresponsible that President Trump and Jair Bolsonaro have put politics over science,” he said in a statement on Twitter.

Studies into the drug’s uses continue. Earlier this month, the first carefully controlled trial of hydroxychloroquine found the drug does not prevent the disease in people who have been exposed to a sick patient.

Also, a prominent medical journal, The Lancet, took the rare step of retracting a widely-read study earlier this month that found the drug could be dangerous in Covid-19 patients. The study, which was withdrawn after its underlying data was called into question, led doctors to halt some clinical trials.

Marcelo Kalichsztein, a prominent pulmonologist in Rio de Janeiro, began prescribing hydroxychloroquine to coronavirus patients soon after they developed symptoms, along with the antibiotic azithromycin and a zinc supplement. He did so having found the research of the French microbiologist, Dr. Didier Raoult, persuasive. But Dr. Raoult’s research was discredited, and the scientific group that published it said later that the paper had not met its standards.

“This is a brand-new disease and we don’t have a silver bullet,” Dr. Kalichsztein said. “We were all searching for a medication that would stop the virus in the very first stage.”

Dr. Kalichsztein, who contracted the virus in early April and took hydroxychloroquine, said the treatment had been effective in preventing the disease from reaching an inflammatory stage among more than 100 patients whose care he oversaw.

Doctors began sharing their experiences with the drug and tips on how to mitigate the risk of heart complications in Zoom meetings and group chats on WhatsApp.
