Minnesota doctors and researchers are on the cutting edge leading the fight in the war against COVID-19. Doctors and researchers at the University of Minnesota and Mayo Clinic are searching for medications that help ease the effects of the virus, including a process of plasma transfer, while also working to develop a vaccine.
MSR’s regular health columnist and medical advisor Dr. Charles Crutchfield helped facilitate interviews with physicians engaged in combatting the pandemic. An expert of our interview with Dr. Michael Joyner appears below.
At Mayo Clinic in Rochester, Dr. Joyner (MJ) is part of a group of experts who are pursuing a unique but time-tested treatment to help patients with COVID-19 fight off the virus. Convalescent plasma treatment has been used historically to treat infectious diseases before the discovery of vaccines.
MSR: What is involved in convalescent plasma treatment?
Dr. Michael Joyner: It involves taking antibody-rich plasma from the blood of patients who have survived COVID-19, then infusing it into those who are ill to help their bodies fight off the disease. The approach is known as “convalescent plasma treatment.”
MSR: Why is it called convalescent plasma treatment?
MJ: It’s called convalescent because the word refers to when people are getting better.
MSR: You spent most of your career as a physiologist. How did you get involved in this?
MJ: That’s true, and I am also an anesthesiologist. What happened is my friend Dr. Arturo Casadevalle at John Hopkins wrote an editorial in the Wall Street Journal discussing the historical use of convalescent plasma.
I reached out to Arturo, and since we have a large network of collaborators, we reached out to them. This was me repurposing my career for a few months in my lab to help attack this problem, to see if we could find some way to push back.
I have thrown in with Arturo and want to help him move this forward. He is our visionary and spiritual leader.
MSR: Tell us who else is involved in this project.
MJ: We have people from about 40 universities and medical centers all over the country from about 20 states working on this, and we are getting cooperation from the Food and Drug Administration. We are trying to get this online right away. It’s already started in New York and Houston, and we hope the pace is going to pick up throughout April.
MSR: The FDA has approved the process but with limitations. Can you explain the limits?
MJ: You have to get special permission. It’s one-off at a time. We are currently working to get an expanded access protocol going so we can begin to collect more [plasma] all over the country and treat more people.
It’s going to be a while until the supply is high. Infrastructure is being put in place to collect it at scale, distribute it, and get it to the people who can benefit from it. And then keep detailed records and make sure we do all the compliance and reporting, get people’s permission, and study it while we are actually using it. We want to do it in a rigorous and ethical way.
MSR: When does this treatment date back from?
MJ: Before 1900 it was tried.
MSR: It appears some people have died from heart failure as a result of contracting the virus. How do you explain this?
MJ: One of the things that can happen when you have an overwhelming infection is you have a condition called myocarditis, meaning the heart becomes inflamed and the efficiency of the pumping action becomes worse. It’s unclear if COVID-19 does anything unusual.
It appears that when you are septic and when you have critical illness, when you have multi-organ failure, typically your heart function goes down as well. It’s unclear if there is any kind of nasty stuff being excreted by this virus.
It’s possible it targets the heart, but we don’t know that yet. My guess is it is more of the general phenomena. Time will tell. We have to do the research.
MSR: How does COVID-19 attack the body?
MJ: It’s not clear exactly how COVID attacks the body. I think we are 80 percent there. We have the general game plan, but the details are still being worked out.
MSR: How are you going to get started in Minnesota?
MJ: There are plans to collect it [plasma] and distribute it nationally. Most of the people we will begin to collect [plasma] from will be in the Rochester and southeastern Minnesota region.
MSR: What is plasma?
MJ: When you look at your blood it is red, but red cells are about 40 percent. The rest is protein-containing fluid that, if you separate it, put it in a centrifuge and spin it around, you will get this kind of yellowish material. That’s plasma. It is the part of the blood that is not the red and white cells, the non-cellular part of the blood.
MSR: What are this treatment’s chances of success?
MJ: It’s too soon to tell. It depends on how sick the patient is. Our best shot is people who are sick but not terribly sick or in the ICU yet. And it may help people in the ICU.
What we are trying to do is bend some curves. We want to stop people from deteriorating as they go from sick to the ICU, and as they get in the ICU and do worse, we want them to stabilize and get better.
