ABSTRACT
Thrombotic thrombocytopenic purpura, an immune/non-immune thrombotic microangiopathy (TTP/TMA) is associated with high morbidity and mortality, even with appropriate treatment. In patients refractory to standard treatment with plasmapheresis there is no certainty about the best therapeutic strategy. This report shows our experience in eight refractory patients who survived after treatment with rituximab.

We have treated 28 patients (pts) with malignant hematological diseases with allogenic bone marrow transplantation (BMT). 18 pts had acute lymphoblastic (ALL) and non lymphoblastic leukemia (ANLL), 5 chronic myeloid leukemia (CML), 2 severe aplastic anemia (SAA), 1 myelodisplasia, 1 Fanconi's anemia and 1 advanced Non Hodgkin's lymphoma. All but three received the graft from HLA identical sibling donors. We used conditioning with total body irradiation and chemotherapy (cyclophosphamide, cytarabine and etoposide) in 17 pts and chemotherapy alone in 11.24 pts had a full hematological recovery 18 to 25 days post BMT. 15 pts died after BMT as a consequence of toxicity or early infection (4), graft failure (2), graft vesus host disease (4) or relapse (5). Actuarial event free survival for the group with favorable prognosis (SAA, ALL and ANLL in first or second remission and CML in chronic phase) is 57 percent at 36 months. Allogeneic BMT is an effective and feasing therapeutic procedure for selected patients with hematological malignancies
