Bone marrow transplantation in chronic GvHD and autoimmune diseases

The same ex vivo marrow's treatment that we used in mismatched BMT (incubation with vincristine and methylprednisolone) was used in two patients with chronic GVHD and in one patient with PRCA. The conditioning regimen with cyclophosphamide and ALG was aimed to kill only the patient's lymphocytes, and did not cause a deep myeloid aplasia. The patients achieved a clear improvement of their symptoms.
