Peanut allergy can be cured after Bone Marrow Transplant ?

A new case study suggests, bone marrow transplants may help cure peanut allergies.

A 10-year-old boy  was cured of his peanut allergy after receiving a bone marrow transplant. He was suffering from leukemia.  The boy’s case was described at the annual American College of Allergy, Asthma and Immunology meeting (ACAAI) on Friday. The patient had a peanut allergy since he was 15 months old.  He vomited and developed hives over his body after eating peanuts.

“It has been reported that bone marrow and liver transplants can transfer peanut allergy from donor to recipient,” study author Dr. Yong Luo said in a news release from the American College of Allergy, Asthma and Immunology (ACAAI). “But our research found a rare case in which a transplant seems to have cured the recipient of their allergy.”

NBC reports that in 2005 UK researches observed a 12-year-old boy lose his peanut allergy after a bone marrow transplant,. In 1999, a 5-year-old’s latex allergy was allegedly cured after surgery correcting a bone marrow disorder.

Bone marrow transplants, NBC adds, come with major risks such as including infection, anemia, bleeding and diarrhea. Because of this, doctors do not suggest using transplants for patients suffering from allergies.

Dr. Steven Weiss, the study’s co-author, told  that prior to the boy’s transplant, he was supervised by his parents.

The boy was given an oral food challenge after the transplant. There was no allergic reaction further.

Peanut allergy is the most common food allergy among school-aged children in the United States, affecting about 400,000 youngsters, according to the ACAAI. Unlike milk or soy allergies, peanut allergies tend to last a lifetime.

Even if a parent thinks their child may no longer have an allergy, proper testing should be done to confirm if the child is still sensitive to any particular allergens, according to the ACAAI.

The ACAAI said children with peanut allergy should always carry prescribed epinephrine.
