More than a month late in seeing your response -- sorry. He's focused on coinfections. He was the lead author of the study on Valcyte, in which 30% of his patients got better *and stayed better* even off the antiviral, and another 30% or so got better but only stayed better if they kept taking the drug. He's about to start a new trial, he says, of another antiviral. His idea is that something causes the immune system to go out of whack, and then coinfections take hold and keep the immune system overtaxed. If you can knock down the coinfections, sometimes the immune system kicks back in.
He also is planning a trail of rituximab, combined with an antiviral. His idea there is that the white blood cells end up being a reservoir for viruses, and that the reason rituximab works is that it kills off the white blood cells where the virus is hanging out. When the bone marrow regenerates the white blood cells, they're uninfected -- initially. But then, over a couple of weeks, they get reinfected. His thought is that if you take an antiviral at the same time, it might be able to knock the infections out entirely.
That's the kind of thing he's researching, but he also looks at the situation more broadly, dealing with the more mundane things like sleep, etc.
