Chronic Graft-versus-Host Disease (GVHD)
Chronic graft-versus-host disease (GVHD) is a serious complication that can occur after a stem cell or bone marrow transplant. It happens when the donor's immune cells, the graft, attack the recipient's tissues, the host.
Cause
Chronic GVHD arises when the immune system of the donor, the graft, mistakenly recognizes the recipient's tissues as foreign. This leads to an immune response that attacks the recipient's body.
1
Immune System Mismatch
The donor's immune cells are genetically different from the recipient's, leading to the recognition of the recipient's tissues as foreign.
2
T-Cell Activation
The donor's T-cells, a type of immune cell, are activated, triggering an immune response against the recipient's tissues.
3
Tissue Damage
The immune response causes inflammation and damage to the recipient's tissues, leading to the symptoms of chronic GVHD.
Symptoms
Chronic GVHD can affect various parts of the body, leading to a range of symptoms that can vary in severity.
Skin Changes
Rashes, dry skin, and changes in skin pigmentation can occur.
- Eczema-like rash
- Psoriasis-like rash
Mouth and Throat
Dry mouth, sores, and difficulty swallowing due to inflammation.
- Painful ulcers
- Oral thrush
Other Symptoms
Eye irritation, joint pain, and gastrointestinal issues can also occur.
- Dry eyes
- Joint stiffness
- Diarrhea
Transmission
Chronic GVHD is not contagious and cannot be spread from person to person. It develops as a consequence of the immune system interaction between the donor and recipient during a transplant.
Immune System Interaction
The condition is not due to an external pathogen or virus, but rather an immune system reaction within the recipient's body.
No Transmission
There is no risk of spreading chronic GVHD through contact, sharing personal items, or close proximity.
Treatment
Treatment for chronic GVHD focuses on managing symptoms and suppressing the immune response.
1
Immunosuppressive Therapy
Medications such as corticosteroids (prednisone) and other immunosuppressants (mycophenolate mofetil, azathioprine) are used to suppress the immune response.
2
Symptomatic Treatment
Treatments include topical therapies for skin symptoms, artificial tears for dry eyes, and medications to manage pain and gastrointestinal symptoms.
3
Physical Therapy
Physical therapy may be recommended to help maintain joint mobility and manage pain.
4
Supportive Care
Ongoing monitoring and supportive care are essential to address complications and improve quality of life.

Prevention and Management
Early detection and proactive management can help mitigate the effects of chronic GVHD.
Regular Monitoring
Regular follow-up appointments with healthcare providers are crucial to monitor for signs of chronic GVHD and manage symptoms.
Skin Care Routine
Establishing a gentle skin care routine with moisturizing products can help alleviate dryness and irritation.
Hydration
Staying well-hydrated can support overall skin health.
Avoiding Irritants
Avoiding harsh soaps, fragrances, and other irritants can help prevent exacerbation of symptoms.
