Risk Factors

Factors that put a patient at risk for VOD
While veno-occlusive disease (VOD) can occur in any patient receiving stem-cell transplant, there are factors that may increase the risk of developing VOD.
These include:
- Some current or prior conditions, such as cancers or noncancerous blood disorders
 - Certain patient characteristics
 - Previously received medications or treatments
 
What factors put a patient at risk for VOD?
Current/prior conditions
- Advanced disease: beyond second complete remission or relapsed/refractory disease
 - Preexisting liver conditions
 - Metabolic syndrome
 - Thalassemia, a blood disorder
 
Patient characteristics
- Older age (in adult patients)
 
Medications/treatments
- Allogeneic stem-cell transplant (stem-cell transplant with cells from another person)
 - Second stem-cell transplant
 - Unrelated stem-cell donor (stem-cell transplant from a donor that is not related to the patient)
 - Current or previous use of drugs that damage the liver, including those used to prepare the bone marrow for stem-cell transplant
 - Female taking the hormone norethindrone, a form of birth control
 
What additional factors put a CHILD at risk for VOD?
Current/prior conditions
- Hemophagocytic lymphohistiocytosis, also known as HLH, an immune cell disease
 - Adrenoleukodystrophy, also known as ALD, a genetic brain disease
 - Osteopetrosis, a bone disease
 - Neuroblastoma, a type of cancer that affects immature nerve tissue
 - Juvenile myelomonocytic chronic leukemia
 - Chronic blood disorders, such as thalassemia or sickle cell disease
