\n

The most comprehensive national study to date has found that convalescent plasma appears to be safe to use on COVID-19 patients, a promising development in the race to find a treatment for the deadly virus. But the study didn’t determine whether the treatment works.<\/p>\n

A team of more than 5,000 doctors from over 2,000 hospitals and laboratories have been testing the experimental therapy<\/a>, which involves transfusing the antibody-rich blood serum of recovered COVID-19 patients into people who are battling the illness.<\/p>\n

Of the 5,000 seriously ill patients who received blood plasma transfusions for the study, fewer than 1 percent experienced serious adverse events. The mortality rate seven days after treatment was 14.9 percent, but the researchers noted the infusion patients were already gravely ill and the rate “does not appear excessive.”<\/p>\n

\u201cWe’re very encouraged that the treatment is safe,\u201d Dr. Michael Joyner, a physiologist at the Mayo Clinic and the principal investigator of the study, told NBC News. \u201cThat was really the first hurdle for us. And showing that it’s safe gives us confidence to move on and begin to try to understand the efficacy.\u201d<\/p>\n

The study, which was co-authored by researchers at several institutions including Michigan State University and Johns Hopkins, hasn\u2019t undergone peer review or publication in a scientific journal. The results were posted on a public server, called MedRxiv<\/a>, so that other scientists and physicians could quickly review the data.<\/p>\n

\u201cI’ve never put a paper on a preprint server before in my life, and I’ve published almost 500 papers,\u201d Joyner said. \u201cWe wanted to get them out there to the treating physicians and the general public as soon as we could.\u201d<\/p>\n

Joyner said the researchers will start receiving data on the treatment\u2019s effectiveness in the next few weeks. He expects to have a \u201cmuch clearer picture\u201d within the next several months.<\/p>\n

\u201cWe’re really trying to build the plane and fly it at the same time,\u201d Joyner added. \u201cAnd the fact that we’re able to get at least some analysis done so quickly, we’re very pleased with that. We hope to do more really almost in real time.\u201d<\/p>\n

Convalescent plasma therapy<\/a> isn\u2019t a new form of treatment. It has been used to fight past virus outbreaks, including Ebola, influenza and SARS.<\/p>\n

But it hasn\u2019t been used widely in the United States for decades, and its effectiveness has never been scientifically established due to a lack of robust trials.<\/p>\n

The study notes that the most common complication of convalescent plasma therapy is transfusion associated circulatory overload (or TACO), which occurs when a patient cannot tolerate the increased blood volume that results from the transfusion of plasma. Researchers were also concerned about the possibility that the antibodies infused into patients could lead to the formation of new infections.<\/p>\n

But the 5,000 transfusions studied resulted in few such complications, the report says.<\/p>\n

A total of nearly 10,500 COVID-19 patients have now received the treatment at facilities across the country, according to the Mayo Clinic<\/a> in Rochester, Minnesota.<\/p>\n

Doctors at Mount Sinai Hospital in New York City, which is part of the national coalition, have used it on more than 350 COVID-19 patients.<\/p>\n

Dr. Nicole Bouvier, one of the leaders of the hospital\u2019s plasma program, said an analysis of their first 39 patients suggests it is most effective when used in the early stages of the virus.<\/p>\n

\u201cIt\u2019s not a magic bullet. It doesn’t cure everybody,\u201d she said. \u201cBut on the whole, patients who have gotten convalescent plasma have gotten better, quicker and more often, than similar patients who didn’t get convalescent plasma.\u201d<\/p>\n

One of those patients was Claudia Garcenot, a New York City woman who contracted COVID-19 about six weeks ago.<\/p>\n

Garcenot is the chief nursing officer at Mount Sinai Brooklyn, a bustling hospital hit by an influx of coronavirus patients throughout the month of March.<\/p>\n

One day near the end of the month, Garcenot felt a wave of fatigue followed by shortness of breath. Her symptoms soon worsened, prompting her to go to a hospital where she tested positive for COVID-19. A chest X-ray revealed she had bilateral pneumonia as well.<\/p>\n

Garcenot went home to recover but her condition worsened as her breathing became more labored.<\/p>\n

She rushed to her hospital\u2019s emergency room.<\/p>\n

\u201cOf course, I heard all those horror stories about this is what happens with COVID,\u201d Garcenot said. \u201cYou get sick. You don\u2019t feel well. Then you get viral pneumonia and then you end up on a ventilator.\u201d<\/p>\n

Garcenot was eventually admitted to Mount Sinai Hospital in Manhattan because no beds were available at her hospital. A few days later, when it appeared she ran the risk of being put on a ventilator, Garcenot found out she was a candidate for convalescent plasma treatment.<\/p>\n

As the medical team described the process, the severity of her condition set in.<\/p>\n

\u201cI really wasn\u2019t a nurse at that moment,\u201d Garcenot said. \u201cI was a really frightened, sick patient, who was worrying about surviving.\u201d<\/p>\n

She received two doses of convalescent plasma April 5, a process that took four hours. Just over a day later, she woke up in the morning feeling like a different person.<\/p>\n

\u201cI remember taking that first deep breath,\u201d Garcenot said. \u201cEven though I still felt the tightness in my chest, I felt like I had oxygen.\u201d<\/p>\n

\u201cI breathed in again and I thought to myself, \u2018It\u2019s got (to be) the plasma,\u2019\u201d she added. \u201cI felt like I\u2019d won the lottery.\u201d<\/p>\n

Some 48 hours later, with her fever gone and her oxygen levels back to normal, Garcenot was discharged from the hospital.<\/p>\n

While researchers may not have yet come to a conclusion about the effectiveness of convalescent plasma, Claudia Garcenot has.<\/p>\n

\u201cI really believe that receiving that plasma treatment is what changed the course of my illness,\u201d she said.<\/p>\n<\/div>\n
