Peanut-allergy skin patch said to show promise
An experimental skin patch may soon allow increased protection for toddlers who are allergic to peanut, according to a new study in the New England Journal of Medicine.
If additional testing pans out, “this would fill a huge unmet need,” said Dr. Matthew Greenhawt, an allergist at Children’s Hospital Colorado who contributed to the study, told the Associated Press. About 2% of U.S. children are allergic to peanuts, some so severely than even a tiny amount can cause a life-threatening reaction. Their immune system overreacts to peanut-containing foods, triggering an inflammatory cascade that causes hives, wheezing or worse. Some youngsters outgrow the allergy but most must avoid peanuts for life and carry rescue medicine to stave off a severe reaction if they accidentally ingest some.
The study, which featured work from dozens of medical doctors in the U.S. and abroad, took samples from 362 toddlers with peanut allergy. The toddlers initially tested to see how high a dose of peanut protein they could tolerate. Then they were randomly assigned to use the Viaskin patch or a lookalike placebo patch every day.
