Allogeneic Bone Marrow Transplantation in b-Thalassemia - Single centre study.
J Pak Med Assoc Jan ;54(10):499-503.

Objective: To evaluate outcome of allogeneic BMT in b-Thalassaemia at the Armed Forces Bone Marrow Transplant Centre, Rawalpindi, Pakistan from August 2001 to November 2003. Methods: Nineteen patients with b-Thalassaemia underwent allogeneic BMT/PBSC transplantation from HLA identical sibling donors. Patients were classified in three groups according to Pesaro (Italy) risk classification. Class-I (n=9) and Class-II (n=7) patients received conditioning with busulphan/cyclophosphamide, whereas Class-III (n=3) patient received conditioning with hydroxyurea, azathioprine, fludarabine, alongwith Bu14/Cy 200. Cyclosporine, prednisolone and methotrexate were given for GvHD prophylaxis. Stem cells dose infused was >4.0x108/kg body weight of the patient. Results: Engraftment was achieved in all Class-I patients, whereas in Class-II and Class-III , graft rejection was observed in one patient from each class. Median time to achieve absolute neutrophil recovery (> 0.5 x109/l) was 13 days, platelet count (>20 x109/1) was 15 days and reticulocyte count (> 0.5%) was 15 days. Acute GvHD was observed in 15 patients. One patient developed grade IV GvHD (liver and skin) and died within 30 days post BMT. Post transplant infectious complications were pseudomonas septicemia, disseminated fungal infection, CMV pneumonia and tuberculosis. Three patients died of these complications during post transplant period (31-90 days). Median stay in hospital was 25 days. Conclusion: Allogeneic BMT is the only curative therapy for b-Thalassemia patients, however the success rate can be increased if the patients are selected carefully and transplanted at an early age (JPMA 54:499;2004).
