Hope for Peanut Allergy Patients in Kansas City

Hope For Peanut Allergy Patients In Kansas City

Dr. Terry Levine, an allergist in Overland Park, Kansas, thought the following information would be quite useful for peanut allergic patients to know about. Peanut allergy and food allergy is a dynamic field of study as best seen by the ever changing views on treatment and prevention.

 

The first ever published data from the highly anticipated Learning Early About Peanut (LEAP) study offers proof that early introduction of peanuts may offer protection from the development of peanut allergies. The study was led by Professor Gideon Lack at King’s College London.

“We believe the results from this trial are so compelling, and the problem of the increasing prevalence of peanut allergy so alarming that new guidelines should be forthcoming very soon,” Hugh A. Sampson, MD, FAAAAI, noted in an accompanying editorial. Sampson is a past-president of AAAAI and current Director of the Jaffe Food Allergy Institute with the Icahn School of Medicine at Mount Sinai.

Lack and the LEAP study team randomly assigned 640 infants with severe eczema, egg allergy, or both, to either consume or avoid peanuts until 60 months of age. Additional clusters were identified in the cohort: children with sensitivity to peanut extract and children without sensitivity (as determined by skin prick tests).

Remarkably, the overall prevalence of peanut allergy in the peanut-avoidance group was 17.2% compared to only 3.2% in the consumption group. The prevalence of peanut allergies in children with negative skin prick tests early in life was at 13.7% in the avoidance group and 1.9% in the consumption group. Similarly, children already sensitive to peanuts reflected a 35.3% prevalence of peanut allergy in the avoidance group, compared to only 10.6% in the consumption group.

“Early consumption is effective not only in high-risk infants who show no sensitivity to peanuts early on, but it is also effective in infants who already demonstrate peanut sensitivity,” first author George Du Toit, MB, BCh, also from Kings College London explained. Introduction of peanuts to already sensitized children should only be done with the supervision of a Board Certified Allergy Physician.

While additional questions remain, researchers now wonder if the LEAP study – which has demonstrated that the early introduction of peanut dramatically decreases the risk of developing a peanut allergy by a staggering 70-80% – should prompt a change in food allergy guidelines.

“There appears to be a narrow window of opportunity to prevent peanut allergy,” says Lack. “As soon as infants develop the first signs of eczema or egg allergy in the first months of life, they should receive skin testing to peanut and then eat peanut products either at home if the test is negative or first under clinical supervision if the test if positive. Infants without such symptoms should be fed peanut products from four months of life.”  In Kansas City, it is the best allergy practice to be supervised by a Board Certified allergist.

Lack added that this advice applies to children in countries where peanut allergy is a problem and cautions that infants should not be fed whole peanuts because of the risk of choking.
