Graft vs. Host Disease (GVHD)
There are two types of GVHD that can range from mild to life-threatening:
- Acute GVHD most commonly occurs within the first 100 days after transplant and, while it can affect any part of the body, it typically affects the patient’s skin, liver, stomach and intestines.
- Chronic GVHD happens more than 100 days after transplant and can reoccur for several years. While it can still affect the same organs as acute GVHD, chronic GVHD more commonly affects the joints, eyes, mouth, lungs and skin.
Before a transplant, the stem-cell donor’s cells and tissue are checked to see how closely they match the person receiving the transplant. GVHD is less likely to occur, or symptoms will be milder, when the match is closer. Additionally, medications can be prescribed to keep this complication to a minimum. The chance of getting severe and life-altering GVHD is:
- Around 30 to 40 percent when the donor and recipient are related
- Around 60 to 80 percent when the donor and recipient are not related
Relation to bone marrow failure diseases:
GVHD signs and symptoms include, but are not limited to:
- Red rash and itching
- Yellow tint to the skin or whites of the eyes (jaundice caused by liver failure)
- Skin changes, including darkening or tightening of the skin
- Abdominal pain
- Diarrhea (large volumes, liquid and frequent)
- Nausea and vomiting
- Joint or muscle pain
- Shortness of breath
- Persistent cough
- Vision changes, such as dry eyes
- Dry mouth
- Mouth sores
- Vaginal dryness
A physical exam and several lab and imaging tests can be done to diagnose and monitor problems caused by GVHD.
A biopsy of the skin, mucus membranes in the mouth, or other parts of the body may help confirm the diagnosis.
After a transplant, the recipient usually takes immune suppressants to reduce the risk of developing GVHD. Patients stay on this medicine until their doctor thinks the risk of GVHD is low. A typical regimen includes the use of cyclosporine or mycophenolate mofetil or tacrolimus or methotrexate.
Clinical trials, also called research studies may offer good treatment options for some people GVHD. These studies also help researchers better understand the value of promising new treatments or procedures.
