A New Twist On Food Allergies In Kids

The current New Yorker unfolds an engaging story on childhood food allergies. As related by Dr. Jerome Groopman, there’s a shift in how some doctors think about how these conditions  are best managed and, even better — might be prevented. The article feeds into recent discussion that medical science, and even dogma, too-often turns out to be incorrect.

Groopman interviews Dr. Hugh Sampson, director of the Jae Food Allergy Institute at Mount Sinai Medical Center in New York:

…“This increase in the incidence of food allergy is real,” Sampson said when we spoke recently. He cannot say what is causing the increase, but he now thinks the conventional approach to preventing food allergies is misconceived. For most of his career, he believed, like most allergists, that children are far less likely to become allergic to problematic foods if they are not exposed to them as infants. But now Sampson and other specialists believe that early exposure may actually help prevent food allergies.”

I recommend the full read if you can get it: Groopman probes potential causes of discordant food allergy rates in children of different geographic regions. I learned a number of details on how some doctors in the U.S. use protein-breakdown methods to desensitize children to food allergies, how in Israel newly-speaking infants are said to ask eagerly for Bamba, a manufactured, peanut-containing snack (which, for the record, I don’t particularly endorse), and how in some cultures parents chew their young children’s food in a manner that might that might facilitate breakdown of complex proteins by enzymes in saliva.

All interesting. Of course it’s hard to know exactly what’s true in this, and the causes of allergies are likely to vary among children. There’s a randomized LEAP study (Learning Early About Peanut Allergy) in the U.K. that may provide some hard evidence on this, one way or another.

Patients As Partners

The famous late 19th and early 20th century physician, Sir William Osler, said that “a physician who treats himself has a fool for a patient.” How would he have felt about patients diagnosing and treating themselves? Would he have written in support of the Journal of Participatory Medicine or against it? I also wonder how he would have practiced medicine in the “information age” when many of our patients present with a diagnosis already made, right or wrong.

I recognize that bringing Dr. Osler into a discussion set in the information age is, perhaps, anachronistic. Yet I believe he still has something to teach the 21st century on the topic of patient participation. When he advised that “the first duty of the physician is to educate the masses not to take medicine,” he offered one of the earliest lessons on a physician’s role as educator.

He also said: “The great physician would treat the patient with the disease while the good physician would treat the disease.” For me, this marches lock-step with the reality of today’s patient as consumer and active participant in the doctor-patient relationship. Simply put, it is impossible to separate the patient from a pre-conceived and often well-researched opinion — correct or not. So to treat the “patient with the disease” requires me to think of my patient as an intellectual partner. Read more »
