I've also heard he's A+ and was a match with everyone besides Duncan (don't know about Amber though -- they haven't said that she's receiving his plasma). If there are any medical professionals reading -- how many times can he give plasma? Seems like he must still be recovering himself, and while is blood/plasma is useful -- is it dangerous to him to be donating or is it regenerated pretty quick? I've read that Whitebold is a rare blood type and hasn't matched with anyone, and I haven't heard anything about Rick Sacra -- the dr. who was treated at Nebraska, though I'm guessing he's also A+ because he got blood from Brantley.

Not sure how much blood they took off, and whether they retransfused his red cells back into him. Either way, he is probably quite anemic, though I am sure he is taking iron, vitamins, and maybe EPO. I heard that they need lots of plasma, something like over a liter (?). The plasma cells make the antibodies, but over time, his supply of antibodies will drop only to spike again with another exposure to Ebola. So, they will have to find new donors.
The problem with Ebola is that it kills you before your body can make the antibodies to fight it. It takes two weeks for the body to produce a good amount of antibody. The transfusions are buying time.

I was listening to the press conference with the dr.s from NIH treating Nina Pham and they were asked if her transfusion from Dr. Brantley is why she's doing so well. Her dr. answered they can't yet scientifically say that's the reason -but yes, it appears it's a huge positive factor.

I wonder if Dr. Brantley is a universal donor (type O-)? He's given blood to so many of the ebola patients here, and to West Africa, etc. Would there be any reason Duncan would have not wanted a blood transfusion (i.e, some religions will refuse blood transfusions no matter how ill)? Brantley apparently called the hospital to offer his blood, and the hospital eventually said they weren't a match. But there's no way Brantley has matched with every single other US patient, is there?

Just curious, don't mean to derail..

The universal donor type for plasma is AB+, Brantley is A+, which means he can donate to anyone who doesn't have B. Since B is pretty rare that's the majority of people.

Those people (now HIV positive who weren't before) would go on to infect other people with HIV, and you've just replaced one problem with another. In any case, Liberia doesn't have the capacity to get everyone suffering from Ebola a bed and Tylenol, so getting them all serum isn't going to happen, either, unfortunately.

For crying out loud. Many Africans are encouraged to breastfeed even with HIV, because it's less risky than feeding infants formula made with contaminated water. HIV is a terrible disease, but there are worse things (well, more rapidly fatal things) out there.

Yes, and the 30% got poor care too. Duncan had relatively better care and still died. My sense is that the reason they aren't rushing for more ZMAPP is that they suspect that the transfusions work better and are more readily available in the US.

Don't know about this, heard ZMAPP just takes a really long time to produce.

ZMapp is grown in plants -- they can't really speed that along.
