Kids With Food Allergies Can Fall Through the Cracks

More can be done to properly manage the care of American children with food allergies, especially when it comes to diagnostic testing and recognizing non-visual symptoms of severe allergic reactions, according to a new Northwestern Medicine study.

“Every child with a food allergy should be diagnosed by a physician, have access to life-saving medication such as an epinephrine autoinjector and receive confirmation of the disease through diagnostic testing,” said lead author Ruchi Gupta, M.D., an associate professor of pediatrics at Northwestern University Feinberg School of Medicine and a physician at the Ann & Robert H. Lurie Children’s Hospital of Chicago. “Not all children are receiving this kind of care.”

The study was published online in the Journal of Allergy and Clinical Immunology, the official publication of the American Academy of Allergy, Asthma and Immunology.

Data in this study is from a randomized online survey of U.S. households with children with symptoms consistent with a mild-to-severe food allergy. It’s the first paper of its kind to offer insight on how pediatric food allergies are typically diagnosed and what can be done to streamline the management of the disease and keep affected children safe.

Here are key findings from the study:

70 percent report receiving a physician's diagnosis for their child's food allergy
Lower income and minority households were more likely to have a child with an undiagnosed food allergy.
Of the physician-diagnosed children, 32 percent did not receive diagnostic testing - such as a blood, skin or oral food challenge test.
A skin test was the most popular diagnostic test with 46 percent. A blood test was second with 39 percent.
Only 1 in 5 of reported that their child received an oral food challenge test - the gold standard of food allergy diagnoses.

"An oral food challenge might be scary for parents because their child is being fed the allergenic food," Gupta said. "Some physicians think the risks outweigh the benefits, but it is the best tool we have to diagnose a food allergy."
