What Is GVHD?
Graft-versus-host disease (GVHD) is a life-threatening complication that can occur after a stem cell or bone marrow transplant. It happens when the donated stem cells or bone marrow (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.
Understanding the Pathophysiology of GVHD
The pathophysiology of GVHD is complex and involves an immune response. When the donated stem cells or bone marrow are transplanted, they can recognize the recipient’s body as foreign and activate an immune response. This response can lead to the activation of immune cells, such as T-cells, which can attack the recipient’s tissues and organs.
There are two main types of GVHD: acute and chronic. Acute GVHD typically occurs within the first 100 days after the transplant and can cause symptoms such as skin rash, diarrhea, and liver dysfunction. Chronic GVHD can occur months or even years after the transplant and can cause symptoms such as skin thickening, joint pain, and dry eyes.
GVHD Symptoms
The symptoms of GVHD can vary depending on the severity and type of the disease. Here are some common symptoms of GVHD:
Skin Symptoms
Skin symptoms are common in GVHD and can range from mild to severe. These symptoms may include:
- Rash: A skin rash is one of the most common symptoms of GVHD. It can appear as a red, itchy, and blistering rash on the skin.
- Itching: Itching is a common symptom of GVHD and can be severe in some cases.
- Skin thickening: Chronic GVHD can cause skin thickening, which can lead to limited mobility and flexibility.
Gastrointestinal Symptoms
Gastrointestinal symptoms are also common in GVHD and can include:
- Diarrhea: Diarrhea is a common symptom of GVHD and can lead to dehydration and electrolyte imbalances.
- Nausea and vomiting: Nausea and vomiting can occur due to GVHD and can lead to dehydration and electrolyte imbalances.
- Abdominal pain: Abdominal pain can occur due to GVHD and can be severe in some cases.
Other Symptoms
GVHD can also cause other symptoms, including:
- Fatigue: Fatigue is a common symptom of GVHD and can be severe in some cases.
- Weight loss: Weight loss can occur due to GVHD and can be severe in some cases.
- Liver dysfunction: GVHD can cause liver dysfunction, which can lead to jaundice, fatigue, and other symptoms.
If you or a loved one is experiencing any of these symptoms after a stem cell or bone marrow transplant, it’s essential to seek medical attention immediately. Early diagnosis and treatment can help manage GVHD and improve outcomes.

Acute GVHD vs Chronic GVHD
When it comes to Graft-Versus-Host Disease (GVHD), understanding the difference between acute and chronic GVHD is crucial for effective management and treatment. While both forms of GVHD share similar symptoms, they have distinct characteristics, timelines, and implications for patients.
Acute GVHD
Acute GVHD typically occurs within the first 100 days after a stem cell transplant. During this period, the donor’s immune cells (graft) attack the recipient’s tissues, leading to inflammation and damage. Acute GVHD can be mild, moderate, or severe, and its symptoms can vary widely.
Common symptoms of acute GVHD include:
- Skin rash or itching
- Diarrhea or abdominal pain
- Liver dysfunction or jaundice
- Fatigue or weakness
- Fever
Acute GVHD can be life-threatening if left untreated or if it progresses to a severe stage. Prompt medical attention is essential to manage symptoms, prevent complications, and improve outcomes.
Chronic GVHD
Chronic GVHD typically develops 100 days or more after a stem cell transplant. This form of GVHD is characterized by a slower onset and a more insidious progression. Chronic GVHD can affect multiple organs and tissues, leading to a range of symptoms and complications.
Common symptoms of chronic GVHD include:
- Skin thickening or sclerosis
- Mouth dryness or ulcers
- Eye dryness or irritation
- Liver dysfunction or cirrhosis
- Lung disease or bronchiolitis obliterans
- Gastrointestinal problems or malabsorption
Chronic GVHD can significantly impact a patient’s quality of life, and its management often requires a multidisciplinary approach involving various healthcare specialists.
GVHD Causes and Risk Factors
GVHD occurs when the donor’s immune cells recognize the recipient’s tissues as foreign and attack them. This complex process involves multiple factors, including:
Genetic Differences
Genetic disparities between the donor and recipient play a significant role in GVHD development. The more genetic differences between the two, the higher the risk of GVHD. This is why GVHD is more common in unrelated donor transplants compared to matched sibling transplants.
Immunosuppressive Therapy
Immunosuppressive medications, used to prevent rejection, can increase the risk of GVHD. These drugs can weaken the recipient’s immune system, making it more susceptible to attack by the donor’s immune cells.
Stem Cell Source
The source of stem cells can influence GVHD risk. For example, peripheral blood stem cells are associated with a higher risk of GVHD compared to bone marrow stem cells.
Recipient Age and Health Status
Older recipients and those with underlying health conditions are more susceptible to GVHD. This is because their immune systems may be weaker, making it more challenging to tolerate the donor’s immune cells.
Understanding the causes and risk factors of GVHD is essential for developing effective prevention and treatment strategies. By recognizing the signs and symptoms of GVHD, healthcare providers can intervene early, reducing the risk of complications and improving patient outcomes. 💊
GVHD Diagnosis and Staging
Receiving a diagnosis of Graft-Versus-Host Disease (GVHD) can be overwhelming, especially when it comes to understanding the severity of the condition. Accurate diagnosis and staging are crucial in determining the best course of treatment and managing symptoms effectively. In this section, we’ll delve into the process of diagnosing GVHD and the different stages of the disease.
Diagnosing GVHD
Diagnosing GVHD typically involves a combination of physical examinations, medical history, and laboratory tests. Your healthcare provider will look for signs and symptoms of GVHD, such as rash, diarrhea, abdominal pain, and jaundice. They may also perform the following tests:
- Complete Blood Count (CBC) to evaluate blood cell counts
- Liver function tests to assess liver damage
- Imaging tests, such as CT or MRI scans, to identify organ involvement
- Biopsies to examine tissue samples from affected organs
In addition to these tests, your healthcare provider may also use the Glucksberg criteria, which is a set of guidelines used to diagnose and stage GVHD. The criteria consider factors such as the severity of symptoms, the number of organs involved, and the response to treatment.
Staging GVHD
GVHD is typically staged based on the severity of symptoms and the number of organs involved. The most commonly used staging system is the IBMTR (International Bone Marrow Transplant Registry) severity score, which categorizes GVHD into four stages:
- Mild GVHD: Limited to the skin, with minimal symptoms
- Moderate GVHD: Involves the skin and one or two organs, with moderate symptoms
: Affects multiple organs, with severe symptoms - Very Severe GVHD: Life-threatening symptoms, often requiring intensive care
Accurate staging is essential in determining the best course of treatment and managing symptoms effectively. Your healthcare provider will work closely with you to develop a personalized treatment plan based on the severity of your GVHD.
GVHD Treatment Options
