article imageMarrow transplant cures peanut allergy

A marrow transplant for child with leukemia not only helped tackle the cancer, it also cured an allergy that the child had to peanuts.
A boy was diagnosed with the peanut allergy at 15 months; and four years old the child developed acute lymphocytic leukemia, according to Science News. After chemotherapy proved to be unsuccessful, at age 10, the boy underwent a bone marrow transplant. A bone marrow transplant is one that kills off a patient’s existing bone marrow and the cancerous cells and then replaces them with marrow cells from a healthy donor.
Interestingly, the boy’s bone marrow donor had no known allergy. A year later, the boy’s immune system had recovered and tests revealed no peanut allergy. Food allergies are abnormal immune reactions to a food protein and this could be linked to the development of immune cells within bone marrow.
Researchers do not know if the bone marrow transplant was the definitive reason for the disappearance of the allergy; however, the coincidence appears to be worth exploring further.
The findings were presented at the annual meeting of the American College of Allergy, Asthma & Immunology.
