Graft-versus-host disease (GvHD) is a serious complication that can occur after an allogeneic stem cell transplant. In an allogeneic transplant, stem cells are donated from a donor who is not an identical twin of the recipient. The stem cells are used to replace the recipient’s damaged or diseased stem cells. GvHD occurs when the donor’s immune cells attack the recipient’s tissues. This is because the donor’s immune cells see the recipient’s tissues as foreign. The severity of GvHD can range from mild to life-threatening. 

The symptoms of GvHD can vary depending on the organs that are affected. Some of the most common symptoms include Skin rash, Diarrhoea, Vomiting, Nausea, Abdominal pain, Jaundice, Liver problems, Mouth sores, Eye inflammation, Lung problems, Intestinal problems, Kidney problems, Heart problems, Neurological problems.

There is no cure for GvHD, but there are treatments that can help to manage the symptoms and prevent the disease from getting worse. The type of treatment that is used will depend on the severity of the GvHD and the organs that are affected.

Some of the treatments that may be used for GvHD include:

Immunosuppressants: Immunosuppressants are drugs that work to suppress the immune system. This can help to prevent the donor’s immune cells from attacking the recipient’s tissues.

Corticosteroids: Corticosteroids are powerful anti-inflammatory drugs that can help to reduce the symptoms of GvHD.

Phototherapy: Phototherapy is a treatment that uses ultraviolet light to help to reduce the inflammation associated with GvHD.

Bone marrow transplant: In some cases, a second bone marrow transplant may be necessary to treat GvHD.

The prognosis for GvHD depends on the severity of the disease and the organs that are affected. In general, the prognosis is better for patients who have mild GvHD. Patients who have severe GvHD have a poorer prognosis.

There are several things that can be done to help to prevent GvHD, including:

Choosing a donor who is as closely matched (HLA Typed) to the recipient as possible.

Using drugs to suppress the immune system before the transplant.

Giving the recipient medications to help to protect their organs from damage.

If you have GvHD, it is important to work closely with your doctor to manage the symptoms and prevent the disease from getting worse. There are several things that you can do to help to live with GvHD, including: 

Taking your medications as prescribed by your doctor.

Avoiding contact with people who are sick.

Getting regular medical check-ups.

Eating a healthy diet.

Exercising regularly.

Managing stress.

Getting enough sleep.

If you have any questions or concerns about GvHD, please talk to your doctor.
