For children born with immunodeficiencies, researchers may have found a better way for them to get the help they need from stem-cell transplants (…)
Children with primary immunodeficiencies have genetic defects in their immune system that leave them open to infection and other complications. Stem-cell transplants can replace the defective immune system with one derived from healthy donor bone marrow, but without a stem-cell transplant, many of these children might die, the researchers noted in a journal news release.
In order to create space for the donor stem cells and prevent rejection, the patient usually undergoes chemotherapy, radiotherapy or both. This chemoradiotherapy can cause severe liver or lung damage, as well as hair loss and sickness. It may also cause problems with growth, puberty and infertility in later life, according to the news release (…)
With this approach, the 16 children with primary immunodeficiencies in this study, who were too sick for a traditional stem-cell transplant, were able to avoid much of the toxicity caused by chemotherapy (…)
