What Is Graft versus Host Disease?
Graft versus host disease (GVHD) is a serious and potentially life-threatening complication that can occur after a bone marrow or stem cell transplant. It happens when the donated bone marrow or stem cells (the graft) view the recipient’s body (the host) as foreign and attack it. This can lead to a range of symptoms, from mild to severe, and can affect various parts of the body.
What Causes Graft versus Host Disease?
The exact cause of GVHD is still not fully understood, but it’s thought to occur when the donated cells recognize the host’s body as foreign and mount an immune response against it. This can happen when the donated cells are not a perfect match for the recipient’s cells, or when the recipient’s immune system is weakened.
Types of Graft versus Host Disease
There are two main types of GVHD: acute and chronic.
- Acute GVHD: This type occurs within the first 100 days after the transplant and can cause symptoms such as skin rash, diarrhea, and liver damage.
- Chronic GVHD: This type occurs more than 100 days after the transplant and can cause symptoms such as skin thickening, dry eyes, and mouth sores.
Graft versus Host Disease Symptoms
The symptoms of GVHD can vary depending on the severity of the condition and the organs affected. Common symptoms include:
- Skin symptoms: Rash, itching, redness, and skin thickening
- Gastrointestinal symptoms: Diarrhea, abdominal pain, nausea, and vomiting
- Liver symptoms: Jaundice, dark urine, and pale stools
- Eye symptoms: Dry eyes, blurred vision, and eye pain
- Mouth symptoms: Mouth sores, dry mouth, and difficulty eating
If you’re experiencing any of these symptoms after a bone marrow or stem cell transplant, it’s essential to seek medical attention immediately. Early diagnosis and treatment can help prevent complications and improve outcomes.

Graft versus Host Disease Causes and Risk Factors
Graft versus host disease (GVHD) is a serious complication that can occur after a stem cell or bone marrow transplant. It happens when the donated cells (the graft) see the recipient’s body (the host) as foreign and attack it. But what causes GVHD, and who is at risk of developing this condition?
What Causes Graft versus Host Disease?
The main cause of GVHD is a mismatch between the genetic material of the donor and the recipient. This mismatch triggers an immune response, leading to an attack on the recipient’s body. The donated cells, which are meant to help the recipient, instead become the enemy, causing damage to various organs and tissues.
There are two types of GVHD: acute and chronic. Acute GVHD occurs within the first 100 days after the transplant, while chronic GVHD develops later, often within a year after the transplant.
Risk Factors for Graft versus Host Disease
Certain factors can increase the risk of developing GVHD. These include:
- HLA mismatch: When the genetic material of the donor and recipient do not match, the risk of GVHD increases.
- Older age: The risk of GVHD increases with age, especially in people over 50.
- Previous transplants: Having had a previous transplant increases the risk of GVHD.
- Donor-recipient sex mismatch: When the donor and recipient are of different sexes, the risk of GVHD increases.
- Intensity of conditioning regimen: A more intense conditioning regimen before the transplant can increase the risk of GVHD.
Understanding the causes and risk factors of GVHD is crucial for preventing and managing this condition. By identifying high-risk individuals, healthcare providers can take steps to reduce the risk of GVHD and improve outcomes for transplant recipients.
Graft versus Host Disease Diagnosis
Diagnosing graft versus host disease can be challenging, as the symptoms can be similar to those of other conditions. However, early diagnosis and treatment are critical for preventing complications and improving outcomes.
