(Within weeks and months after the transplant)
Acute graft versus host disease (aGVHH) is a common side effect in allogenic transplants; Immune system cells (graft) from the donor attack the body of the transplant patient (host). GVHH can affect the skin, stomach and intestines, liver, and even other parts of the body. It can range from mild to life threatening seriousness.
Mucositis is a common side effect of full density allogenic and autologous transplants and wound on the mouth surface. It is similar to aphtha sores, but it is more common in the mouth and throat and makes it difficult to eat and drink. This effect is temporary and resolves without discharge from the hospital after transplantation. Medication can be used to reduce pain.
