Erin Brazil is frustrated. She’d hardly had time to digest the peanut allergy study that got heavy media coverage this week when, she says, she got “inundated by calls and emails and Facebook posts saying ‘There’s a cure, there’s a cure!’ ”
Brazil is a Boston food-allergy activist whose 4-year-old son Gabriel is severely allergic to peanuts and other foods. So she knows better than anyone that the new study, while a landmark in the field, represents no cure. “It doesn’t do anything for Gabriel,” she says.
What it does mean is that many future children will be able to avoid a life of worry about whether the merest trace of peanut protein — even an invisible smear from a candy bar left by another child on playground equipment — could send them to the emergency room gasping for breath.
I can finally look a mother in the eye and give her some advice that I feel confident in.
And the new study means that the recommendations parents have been given over the past 15 years — to withhold peanuts until the age of 3 in children deemed at risk — “were exactly wrong,” says Dr. Wayne Shreffler, director of the Food Allergy Center at Massachusetts General Hospital.
“I strongly suspect they made things worse,” Streffler adds, because at-risk children who were deprived of peanut exposure in food during infancy were more likely to suffer a lifelong allergy from later exposure to, say, house dust. It’s almost impossible to avoid it.
In 2008, the American Academy of Pediatrics withdrew its recommendation to withhold peanuts until age 3, but until now there’s been no solid evidence in favor of deliberately feeding peanuts to at-risk kids. That’s what the new study strongly suggests parents should do — strictly under the supervision of their pediatricians. That flip-flop is widely expected to be enshrined in the next set of official guidelines.
It’s a big change, but not only does it offer nothing to children like Gabriel who already have peanut allergy, it provides no answer to the really big question: Just why have food allergies soared lately, more than quadrupling among the current generation of American children?
Even though the study doesn’t solve that mystery, allergy experts say it’s certain to accelerate research already under way to unravel the causes and devise treatments, if not outright cures.
Six million U.S. children currently have food allergies, one out of every 13 kids, according to the largest recent study. Peanut allergy is the most common, and the most troublesome — not only because it’s so hard to avoid exposure, but because peanut allergy is usually permanent, unlike those involving other foods. And peanut allergies are more likely to be fatal.
That explains why allergists are so enthusiastic about the new study. Continue reading
