Hematopoietic stem cell transplantation for inborn errors of metabolism: A report from the Research Committee on Transplantation for Inborn Errors of Metabolism of the Japanese Ministry of Health, Labour and Welfare and the Working Group of the Japan Society for Hematopoietic Cell Transplantation
Abstract
A total of 216 patients with IEM were treated by allogeneic HSCT in Japan from 1985 until 2010. The results of UCBT have improved, and the OS rate of UCBT (81.9%) was not different from those of RBMT (87.2%) or UBMT (73.9%) in 2000-2010. However, EFS rates in RBMT (73.2%) and UBMT (62.2%) were better than that in UCBT (49.5%), and the difference between RBMT and UCBT was significant (p = 0.01). The EFS rate of patients conditioned by RIC (74.6%) was comparable or slightly better than in those who underwent MAC with irradiation (57.9%) or without irradiation (54.2%) in 2000-2010. A more pronounced trend was observed toward differential EFS for UCBT in 2000-2010: RIC (62.9%), MAC with irradiation (20.0%), and MAC without irradiation (42.1%). The difference between RIC and MAC with irradiation was significant (p < 0.03). In summary, we report a Japanese registry analysis of HSCT for IEM with improving survival in UCBT. The introduction of RIC after 2000 was considered to contribute to this improvement. UCBT could be recommended for those who lack an HLA-identical sibling donor.

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.
Alternative Complement Pathway
The Alternative Complement Pathway is part of the innate immune system, and activation generates membrane attack complexes that kill pathogenic cells. Discover the latest research on the Alternative Complement Pathway.
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.
