Thanks for the query.
There are different modalities. The treatments depend on severity of the problem. If it is less severe the immune-modulator medications-Antithymocyte globulin
(ATG), cyclosporin (CSA), and cyclophosphamide
are useful. She requires intermittent blood transfusions.
If it is more severe, she needs Bone Marrow transplantation
(BMT) from appropriate donor which is the definitive treatment. She needs conditioning before transplantation with ATG/cyclophosphomide so that the graft (BMT) will not be rejected.
