The GVHD medical abbreviation stands for graft versus host disease, a complication in which immune cells from a donor see the person who received them as foreign and attack their tissues. It occurs mainly after an allogeneic stem cell or bone marrow transplant, meaning one that uses cells from another person.
The graft is the donated cells, and the host is the patient. GVHD is the reverse of the usual rejection problem in organ transplants, where the patient's immune system attacks the new organ. You will see the term in transplant clinic notes, oncology records and hospital summaries, often with the word acute or chronic and a grade.

Why graft versus host disease happens
A stem cell transplant replaces a patient's blood forming system with a donor's. The new system includes T cells, a type of white blood cell that guards against infection. If these donor T cells recognize the patient's tissues as different, they can attack them. Closer donor matching lowers the risk but does not remove it.
The same donor immune activity has an upside. Donor cells can also attack leftover cancer cells, an effect called graft versus leukemia or graft versus tumor. Transplant teams try to keep that benefit while limiting harmful GVHD, which is why patients are usually started on preventive medicines around the time of transplant.
Acute and chronic GVHD compared
The two main forms are now told apart mostly by their features, not only by timing, although acute GVHD tends to appear earlier and chronic GVHD later.
| Feature | Acute GVHD | Chronic GVHD |
|---|---|---|
| Typical timing | Often in the first months | Often later, can last years |
| Common targets | Skin rash, liver, intestines | Skin, mouth, eyes, lungs, joints, liver, gut |
| Typical signs | Rash, diarrhea, raised bilirubin | Dry eyes and mouth, skin tightening, shortness of breath |
| Severity scale | Graded, often I to IV | Scored as mild, moderate or severe |
A small number of people have features of both, sometimes called overlap syndrome.
Reading the GVHD medical abbreviation in a transplant note
Transplant clinic note: "Day +28 s/p allo HSCT for AML. Grade II acute skin GVHD, started prednisone, continue tacrolimus." The patient is 28 days after an allogeneic hematopoietic stem cell transplant done for acute myeloid leukemia. A moderate rash from acute GVHD has appeared, steroids have been started, and an anti rejection medicine continues.
Transplant teams count days from the transplant itself, called day 0, so day +28 is four weeks later. HSCT and HCT both mean hematopoietic stem cell transplant.
Prevention and treatment in broad terms
Most allogeneic transplant patients receive medicines to dampen the donor T cells. Common choices include tacrolimus or cyclosporine, methotrexate, mycophenolate mofetil and post transplant cyclophosphamide, combined in different ways by each center. When GVHD develops, corticosteroids such as prednisone or methylprednisolone are usually the first treatment, with skin creams or eye drops for local symptoms. If steroids do not control it, other medicines such as ruxolitinib may be used. The exact plan depends on the organs involved, the severity and the transplant team's protocols.
A rare cousin: transfusion associated GVHD
Very rarely, GVHD follows a blood transfusion rather than a transplant, when donor white cells in the blood product attack a patient whose immune system cannot clear them. This form is usually severe. To prevent it, people at risk, such as transplant patients and some people with blood cancers, receive irradiated blood products, which disable the donor white cells. Charts may note irradiated products only as part of standard orders.
Frequently asked questions
What does GVHD stand for?
GVHD is a medical acronym for graft versus host disease. Immune cells that came from a donor's marrow or blood stem cells attack the tissues of the person who received them.
Is GVHD the same as transplant rejection?
No, it is roughly the opposite. In rejection the patient's own immune system attacks a donated organ or cells. In GVHD the donated immune cells attack the patient.
Can you get GVHD from your own stem cells?
It is very uncommon. An autologous transplant uses the patient's own cells, which recognize the body as self, so GVHD risk is low. It is mainly a complication of allogeneic transplants from a donor.
What is the difference between acute and chronic GVHD?
Acute GVHD usually involves the skin, liver and intestines and tends to appear in the first months. Chronic GVHD can affect many more organs, such as the eyes, mouth, lungs and joints, and often appears later and lasts longer.
What does grade II GVHD mean?
Acute GVHD is graded by how much the skin, liver and gut are involved, often from I, the mildest, to IV, the most severe. Grade II is moderate and commonly leads to treatment with steroids.
