Summary
Bone marrow stem cell transplantation is a feasible treatment for thalassemia major, offering a new therapeutic option. This successful case in China demonstrates improved hemoglobin levels and reduced transfusion dependence post-transplant.
Area of Science:
- Hematology
- Transplant Immunology
- Pediatric Medicine
Background:
- Thalassemia major is a severe inherited blood disorder requiring lifelong transfusions.
- Hematopoietic stem cell transplantation (HSCT) is a potential curative treatment.
- Feasibility of HSCT in resource-limited settings remains a key question.
Observation:
- A 4-year-old patient with beta-thalassemia major underwent allogeneic HSCT from a HLA-mismatched sibling donor.
- The conditioning regimen included Busulfan, cyclophosphamide, and lymphoglobuline.
- Post-transplant complications included grade II acute graft-versus-host disease and cytomegalovirus interstitial pneumonia, which were successfully managed.
Findings:
- Successful engraftment was achieved, with normalization of platelet counts and sustained hemoglobin levels above 110 g/L without transfusions.
- The patient's gene type converted to donor's CD41-42/N heterozygen.
- Complete resolution of transfusion dependence was observed.
Implications:
- This case demonstrates the successful application of HSCT for thalassemia major in China, expanding treatment options.
- The findings support the use of HSCT as a potentially curative therapy for thalassemia major.
- Effective management strategies for post-transplant complications like CMV pneumonia are crucial for successful outcomes.
