Abstract

A 25-year-old man with AML, who relapsed 21 months after his first allogeneic bone marrow transplant (BMT), underwent a second transplant with peripheral blood progenitor cells (PBPC) obtained from his HLA-identical sibling. The donor cells were collected through four aphereses after G-CSF mobilization with 5 micrograms/kg/d for 5 days. The patient received BAVC conditioning regimen followed by non-T cell-depleted PBPC. Successful engraftment occurred with rapid hematopoietic recovery (time to reach 0.5 x 10(9)/L neutrophils and 50 x 10(9) platelets/L was 15 and 19 days, respectively). A bone marrow aspirate on day +19 showed trilineage engraftment. Erythrocyte phenotype showed that erythropoiesis was of donor origin. The patient developed grade II acute GVHD that responded to prednisone. Seven months after PBPC transplantation he remains in complete remission, alive and well, with just limited chronic GVHD. Allogeneic peripheral blood progenitor cell transplantation may be considered a suitable alternative to marrow transplant.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
