Preventing GVHD: calming donor cells

Graft-versus-host disease (GVHD) is when donor immune cells attack the patient's tissues. Prevention starts before the transplant and continues for months.

01Short answer

GVHD can affect the skin, liver, gut, mouth, eyes and lungs. Prevention uses medicines that suppress the immune system, cyclophosphamide after the transplant and antibodies against T cells. The challenge is balance: donor cells also act against the leukaemia (the graft-versus-leukaemia effect), so too much suppression may raise the relapse risk. New medicines and methods are being studied.

02Simple explanation

Donor cells may attack.

Prevention lasts months.

Balance matters.

Report changes.

03Scientific explanation

NCI: GVHD is a condition in which a donor's cells attack the recipient's normal tissue.

NCI: new treatments are tested step by step, from the laboratory to clinical trials; only those proven safe and beneficial become standard care.

04What happens in the body?

Signs

Rash, diarrhoea, jaundice, dry eyes and mouth, breathlessness.
