Acute Graft versus Host Disease (aGVHD)
Acute GVHD is a potential complication following an allogeneic stem cell transplant, where donor immune cells (the graft) mistakenly attack the recipient's healthy tissues (the host).
Common Areas Affected
- Skin - Rash, redness, burning, or peeling. Often starts on the palms, soles, or trunk
- Gastrointestinal tract - Nausea, vomiting, abdominal pain, diarrhea, or loss of appetite
- Liver - Jaundice (yellowing of skin or eyes), abnormal liver function tests
Causes and Risk Factors: GVHD occurs when donor T cells recognize the recipient's cells as foreign and begin attacking them. Risk factors include:
- HLA mismatch between donor and recipient
- Older age (patient or donor)
- Donor of a different sex, especially female donors for male recipients
- Donor history of pregnancy
Treatment Options: Treatment is tailored based on severity and organ involvement. Ongoing monitoring is essential.
- Immunosuppressive medications
- Corticosteroids
- Topical treatments
- Biologic medications

The longer you go, the safer you are and won't get GVHD

Myth
It only affects the skin
Reality
GVHD can affect internal organs, and symptoms may not be visible
💡Tips
Speak up - even if the symptom feels small or vague
Keep a daily log of changes in skin, digestion, or energy levels
Ask for visuals or examples of what symptoms might look like
Don't wait for symptoms to worsen before calling your care team
