Could Peanut Allergy Fix Be More Peanuts?
March 15, 2009— -- Eight-year-old Daniel Clowes is so allergic to peanuts, even a tiny bite of a candy bar can create a life-threatening allergic reaction.
His mother, Gina, described a harrowing incident when Daniel was at a friend's house and spotted some innocent-looking candy.
"My son asked his 5-year-old friend, 'Does this have peanuts in it?' and his friend said 'No.' Well, it certainly did, and we ended up in the emergency room," Gina Clowes said.
Daniel also suffers from other severe food allergies to eggs and milk.
But an increasing number of studies are giving hope to children with food allergies. The latest findings were presented at a meeting of the American Academy of Allergy, Asthma, and Immunology in Washington.
In the study, conducted at Duke University and Arkansas Children's Hospital, 33 children with peanut allergies were given carefully measured, incremental doses of peanuts. The initial doses were as tiny as one-1000th of a peanut and were administered in powder or liquid form.
Over several months, the children were given increasing doses, until they were consuming up to 15 peanuts per day without an allergic reaction. The most important finding was that half of the children who completed two and a half years of the therapy -- five children -- are now allergy-free.
"They're eating peanut butter and jelly sandwiches," said Dr. Wesley Burks, chief of the Division of Pediatric Allergy and Immunology at Duke. "They're not having allergic reactions and we really anticipate [the immunity] will last for the rest of their lives."
Most of the other study participants continue to receive daily maintenance doses of peanuts.
Burks said that results from this study could aid in developing treatment for many types of food allergies, "in the next few years."
With 3.3. million Americans suffering from nut allergies, that is reason to be hopeful. Children and adults with severe peanut allergies have been known to go into anaphylaxis or even die from exposure to even a minute amount of peanuts or other nuts.
