I am going to go with the Valcyte
HTree - but not having it until 2014 likely, as I am trying to save up in the meantime. I don't know about the Rituxan, but it kind of seems to have gone a little quiet on that front and I think an AV would be a better bet as a first line treatment. I believe I was offered it, not just because I had mine triggered by GF, but because I am relatively young (26) and don't mind the risk associated with it.
I don't know if Dr K uses imunovir, but it wasn't mentioned at all, so my gut reaction would be no.
Do you see Dr K?
