Boy cured of serious peanut allergy with cancer treatment


A boy who was cured of his peanut allergy after undergoing cancer treatment has become the subject of a research paper presented by allergist Dr. Steven Weiss of the American College of Allergy, Asthma and Immunology.

The boy was first diagnosed with a severe peanut allergy at 15 months of age. At age 4, still allergic to peanuts, the boy was diganosed with acute lymphocytic leukemia.

His first treatment series did well, but he suffered a relapse and required a bone marrow transplant. The transplant was successful, and remission from the cancer was achieved.

A surprising side effect

Two years later, testing by Weiss confirmed that the boy was also no longer allergic to peanuts. Weiss tested the boy because of research already done that indicated the opposite.

"There is published data [indicating that] someone who gets a liver transplant or bone marrow transplant might develop the allergies that the [donor] had," Weiss said in a statement. "Let’s say you have a peanut allergy, potentially that could be transferred by marrow transplant to the person receiving [the transplant]. This is the opposite."

It is possible that this new understanding could lead to future treatments or cures for peanut allergies and other similar allergic responses.
