Plasma Awareness Week

You Should Donate Blood (But Not Like This)

I missed promoting National Blood Donation Week, which was September 1-7. And International Plasma Awareness Week (IPAW) just ended and was held October 3-7. This is promoted by the Protein Plasma Therapeutic Alliance (PPTAglobal.org), which is also involved in hemophilia. There are still factor products made with human plasma, so it’s always good to donate!

But don’t think it’s like the following donation story!  I love reading about medical history, especially about the men and women who discover cures and breakthroughs. One of my favorite stories is the history of blood, particularly how physicians and researchers employed it and through research and trial and error, learned how to properly transfuse. And since I wrote about vampires and vitalism (sort of like a blood transfusion!) last week, let’s visit this story.

Blood letting

The ancient Greeks saw all phenomena as the result of the interaction of four elements: air, fire, wind, earth. In the body, this manifested as “humors”: phlegm, choler, bile, and blood. The Greeks believed good health meant maintaining a balance in the humor, so draining blood (“blood-letting”) and purging the digestive system should help restore balance.

One of the first human blood transfusion first took place in Paris, in the 17th century. It took a wild and undiagnosed insane man, Antoine Mauroy, to help change the course of history.

One night in 1667, in a frenzy, he stripped off his clothes and ran through streets of Paris, setting fires. Dr. Jean-Baptitste Denis, physician to king Louis XIV, had been experimenting with transfusing blood from animals into humans. He had his “aha” moment: let’s try this on Mauroy.

He infused ½ cup of calf’s blood into the mentally besieged man. Why calf’s blood? He believed that since the calf was a calm animal, its blood would be calm. Infusing it into Mauroy should calm the wild man.

Dr. Jean-Baptitste Denis

This belief was called “vitalism,” that the blood somehow carried the essence of the creature. A stag’s blood carried courage; a horse’s, strength. A calf, calm. 

Prior to this experiment, other physicians had dabbled in transfusions with animals. Richard Lower, an English physician, tried transfusing blood from one dog to another: he figured out how to infused from an artery into a vein and it worked. His findings about the transfusion of blood are often ranked among the most important discoveries in medical history. And he is still remembered one of Oxford’s finest doctors. The English medical community worked on transfusions a year before Denis.

Dr. Denis had also tried transfusions in humans twice before, successfully.

So back to the madman. Unfortunately, Antoine Maury eventually died after the third infusion. Dr. Denis was accused of murder, and later acquitted, but it turned out that Maury’s wife poisoned Maury! He wasn’t the only wild one in that family. Human transfusions were stopped, and another 150 years would pass before they were attempted again.

And since it’s almost Halloween, I would add, unless you include vampires.

Plasma Awareness Week

This week marks the first ever International Plasma Awareness Week, an opportunity to recognzie the importance of plasma in our lives, and the need to donate blood to provide the life-saving liquid to those in need. It’s especially important to many with hemophilia throughout the world as donated blood donations can be fractionated into factor VIII and IX for many hemophilia patients who use plasma therapy.
You learned this in high school science class but here it is again: Plasma is the clear, straw-colored liquid portion of blood that remains after red blood cells, white blood cells, platelets and other cellular components are removed. It is the single largest component of human blood, comprising about 55 percent, and contains water, salts, enzymes, antibodies and other proteins. It is a clear, straw colored liquid that is 90% water and serves as a transporting medium for cells and a variety of substances vital to the human body.
In the US, we often think only of recombinant factor when we think about treating hemophilia, but plasma therapies remain the mainstay for many with hemophilia, those with inhibitors and undergoing ITI, and those with von Willebrand disease patients.
In addition, plasma protein therapies are used to in emergency and surgical medicine.Plasma protein therapies are not interchangeable and have been defined by regulators as sole-source biologic products because no generics or substitutions exist. In addition, their biological nature demands storage and handling requirements by specialty distributors that ensure their safety.
Source plasma is plasma that is collected exclusively for further manufacturing through a process called plasmapherisis. Recovered plasma is collected through whole blood donation which has been separated into its cellular components.
Safety and quality of plasma protein therapies is the top priority of the plasma protein therapeutics industry. Both collectors and manufacturers adhere to strict regulatory policies and have instituted Good Manufacturing Practices in every step of plasma collection and manufacturing processes.

Plasma-derived therapies depend on the generosity and commitment of healthy donors. Source plasma is collected in over 450 specialized donor centers in the U.S., Canada, Germany, Austria and the Czech Republic. Source plasma collection in the U.S. is regulated by the Food and Drug Administration and by the European Medicines Agency and national regulatory authorities in Europe. Additionally, 436 plasma collection centers are also certified by the International Quality Plasma Program (IQPP), a rigorous, voluntary program that goes beyond regulatory requirements to help ensure donor safety and further improve the quality of plasma used to manufacture therapies.
This is a good week to donate blood then! If you can make the time, please visit your local blood donation center and give the gift of life.
See www.donatingplasma.org and www.pptaglobal.org  for more information.

International Plasma Awareness Week is sponsored by the Plasma Protein Therapeutics Association and its member companies.
