Background

  • Sickle cell disease effects the black population and is responsible for many hospitalizations and a high consumption of red blood cell transfusions.
  • The only definitive cure remains a bone marrow transplant.
  • However, the risks of a allogenic transplant must be wieghed by the incremental benefit that it will offer.
  • This is a multi country and multi center trial looking at allo-transplants in sickle cell patients.

Materials and Methods

  • 69 patients with sickle cell disease were taken to transplant.
  • Pt age varied between 9 and 22 years.
  • 38 of these pts had previous vascular events due to thier disease. 6 had severe transfusion requiring anemias, 25 had more than 3 crisis per year, and 7 pts were previously treated on Hydroxyurea.
  • 65 pts had identical matched transplant whereas 7 had a cord blood transplant.
  • three different conditioning treatments were used: Busulfan with Cytoxan, Busulfan, Cytoxan and TBI, and Busulfan, Cytoxan and ATG.

Results

  • 68 of the 69 pt had engraftment. One did not engraft.
  • 7.2% of the pts experienced graft rejection. However no pts who received ATG had graft rejection.
  • There were 6 deaths: one due to sepsis, 1 to a cerberal hemorrhage and 4 to GVHD.
  • Event free survival at 54 months was 85%.
  • Overall patients had long lasting improvements in transfusion requiremenets, veno occlusive crisis, and cerbral events.

Author's Conclusions

    Allo transplants offer a viable choice for sickle cell pts.
  • The main complications are those related to GVHD so techniques that decrease the incidence and severity of GVHD should be investigated in these pts.

Clinical/Scientific Implications

    Sickle cell disease can be very debilitating causing both severe medical and emotional consequences. This study shows that allo transplant is a viable option for those willing to take the inital risks of transplant for a life long cure from Sickle Cell anemia.

Higher-dose opioid medication use linked to more severe delirium post-stem-cell transplantation

Jan 28, 2011 - Pre- and post-transplantation risk factors may be able to assist in identifying patients at risk for delirium onset and severity during the acute phase of myeloablative hematopoietic stem-cell transplantation, according to a study published online Jan. 24 in the Journal of Clinical Oncology.
