What are the signs and symptoms of acute graft versus host disease that acute myeloid leukemia patients should watch out for?
Most patients will have these things read to them pretty clearly before they ever get out of the hospital for their transplant. But the typical symptoms, we talked about the organ systems that are involved. So number one is a rash, a rash of any type. Acute graft versus host disease can look like some small patchy area of redness that you wake up with in the morning. And if you don't sort of tell anyone about it or intervene on it and you wait sometimes eight or 12 hours, that can blossom into something that looks like a full blown bad suntan like you laid out at the beach all day. So any rash is something worth reporting to your doctor.
The second would be if we're considering sort of the upper GV, HD, we think about nausea, vomiting, food intolerance. For some people it's as minimal as just not having much of an appetite, just certain foods don't go down well. And this is one of our trickiest sort of organ systems to diagnose in a way because it very much overlaps how almost every transplant patient feels coming out of the hospital having experienced a transplant and having to take a lot more new meds.
So it's tricky, but deviation from baseline or symptoms that just kind of don't improve in the time course that we expect from those other things are what we want patients to pay attention to. For lower GI it is really very classically watery, crampy diarrhea. Some people will have more on the pain side in their belly, some people will have less, but everybody would have diarrhea.
The last is in terms of the liver being the organ that's involved is really more something that's picked up on labs. Most people who have acute GVHD of the liver, they might notice that they have a yellowing of their skin or their eyes, which is a marker of jaundice. And for most people we just see it on the blood brick that we keep an eye on.
