The FDA has given approval for Houston Methodist to use transfusions from people who have recovered from the virus. The goal is to pass along anti-bodies. The idea isn't new The concept dates back more than a century, when similar treatments were used during the Spanish flu pandemic. Scientists have been recruiting donors from patients and each give a quart of plasma per donation, in a procedure much like donating whole blood. One of the donors is Houston attorney Troy Chandler. He first went to the ER March 12th and was told it was likely allergies. He says over the next six days, his symptoms got worse and returned to the Houston Methodist where he tested positive. He says the worst symptoms lasted two weeks. "The weirdest one was loss of taste and smell. The worst one was a truck hit you' type of fatigue. It was horrible. I slept 20 hours a day. and had to hold myself up on the counter as I went from my bed to the bathroom. One night, it was so bad I fell over in the bathroom while I was using it, and put a big, doorknob shaped hole in the wall behind me and just fell on the floor. I said that's it, I'm not moving."He stayed there until his wife checked on him in the morning. He says he's never experienced fatigue like this. "I'm a healthy, 6 foot two. 250 pound guy with no risk factors and this just hit me like a truck."He has been tested to confirm he has antibodies. He's now given plasma three time and plans to do so twice a week. He does not want to be praised. "I kind of think that's a little ridiculous. There are nurses and doctors going into ICUs and ERs without adequate protections and equipment and getting the virus themselves and getting sick. What I'm doing is the least anybody I would think would do. Who wouldn't do it if they could? The people at Methodist who did this and are getting it to the right people are amazing."
