![]() Rash is the most common symptom of GVHD of the skin.Early detection and treatment may help limit the severity of GVHD. Call your transplant team immediately if you have any of these symptoms. Patients must be aware of the symptoms of acute GVHD. Some may be mild, and some can be severe and even life-threatening. Signs and symptoms of acute GVHD most often affect the skin, gastrointestinal (GI) tract or liver. Receiving total body irradiation as part of the conditioning regimen.Female donor for male recipient y Intensity of the transplant conditioning regimen.Unrelated donor-receiving stem cells from an unrelated donor even if the donor is a perfect HLA match.HLA mismatch-receiving stem cells from a related donor who is not a perfect HLA match.The following risk factors are usually associated with an increased change of moderate to severe acute GVHD: Somewhere between 30 to 70 percent of transplant recipients develop acute GVHD. It can affect the skin, the liver and the gastrointestinal (GI) tract (stomach, intestines and colon). Acute GVHDĪcute GVHD usually develops within the first 100 days after transplantation, but it can occur later. That is why it is important for the donor’s stem cells to have HLA markers that are as similar to the patient’s as possible-to prevent the donor’s cells from attacking the patient’s cells, leading to GVHD. If they find cells with a different pattern of markers, they will attack and kill those cells. These white blood cells know which pattern of HLA markers is normal for a person’s body. They tell white blood cells in the immune system which cells belong in the body and which ones do not. HLA markers play an important role in the body’s immune response to foreign substances such as bacteria and viruses. Except for identical twins, everyone has different HLA markers. There are many HLA markers, and different people have different patterns of markers. Human leukocyte antigen (HLA) typing, also called “tissue typing,” is a test done to identify proteins called HLAs found on the surface of most cells in the body. Importance of Human Leukocyte Antigen (HLA) Typingīefore an allogenic stem cell transplant, the patient and the potential donor are tested to see if the donor’s stem cells are a good match for the patient. Patients may develop one type, both types, or neither type. GVHD occurs when the donor stem cells (“the graft”) attack healthy cells in the patient (“the host”), causing the condition “graft-versus-host disease” or GVHD.There are two main categories of GVHD:Įach type affects different organs and tissues and has different signs and symptoms. Then they are replaced with healthy stem cells from a donor. In this treatment, a patient’s own damaged or diseased blood-forming stem cells are destroyed. ![]() Graft-versus-host disease (GVHD) is a potentially serious complication of allogeneic stem cell transplantation and reduced-intensity allogeneic stem cell transplantation. ![]()
