Overview
The clinical presentation of GvHD can be quite diverse, depending on the types of organs affected and the severity of the immunologic reaction.
History and Symptoms
Classically, acute graft-versus-host-disease is characterized by selective damage to the liver, skin and mucosa, and the gastrointestinal tract. Newer research indicates that other graft-versus-host-disease target organs include the immune system (the hematopoietic system, such as the bone marrow and the thymus) itself, and the lungs in the form of idiopathic pneumonitis. Chronic graft-versus-host-disease also attacks the above organs, but over its long-term course can also causes damage to the connective tissue and exocrine glands.
- GI GvHD: Acute GVHD of the GI tract can result in severe intestinal inflammation, sloughing of the mucosal membrane, severe diarrhea, abdominal pain, nausea, and vomiting. Diarrhea is typically large-volume, and bloody stools can also develop.[1] The volume of diarrhea determines the stage of GI GvHD. This is typically diagnosed via intestinal biopsy, which can be done via endoscopy or colonoscopy.
- Liver GvHD: Acute liver GvHD is measured by the bilirubin level in acute patients.[1] The degree of bilirubin elevation determines the stage of liver GvHD. This can be diagnosed via liver biopsy.
- Skin GVHD: This results in a diffuse maculopapular rash, sometimes in a lacy pattern. This can be diagnosed via skin biopsy.
Acute GVHD is staged as follows: overall grade (skin-liver-gut) with each organ staged individually from a low of 1 to a high of 4. Patients with grade IV GVHD usually have a poor prognosis. If the GVHD is severe and requires intense immunosuppression involving steroids and additional agents to get under control, the patient may develop severe infections as a result of the immunosuppression and may die of infection.
