Peanuts for a Peanut Allergy?

It almost seems counterintuitive. With almost 3.3 million people suffering from allergic reactions when they eat or even come in contact with peanuts or tree nuts, almost two-thirds of whom are children, this type of allergy can prove deadly. In fact, last year there were 150 deaths caused by ingesting, either by mouth or through skin contact.

The American Academy of Allergy, Asthma and Immunology Research believes they may have the answer to a peanut allergy: give them peanuts. The dose begins in many instances with one-thousandth of a peanut with gradually increasing amounts. The experiment lasted for over two years and was conducted among 33 children. Powdered forms of peanuts were sprinkled on the child's food (in other words, don't try this experiment at home on your tot) with six children receiving a placebo. (A placebo is how science determines the results of the experiment by administering fake doses with real ones.)

The study, conducted at Duke University and Arkansas Children’s Hospital in Little Rock, found that most of the children who received the powdered form of the peanuts, in gradually increasing doses suffered from no allergic reaction - five of the children did so well they dropped out of the study because of the significant increases in their tolerance for the nut.

Parents should know that there are still no concrete findings on why these children develop this allergy. According to the Cincinnati Center for Eosinophilic Disorders they have looked at numerous possibilities, ruling out a few along the way and being surprised by others. Worries over what a mother had eaten while pregnant were studied. The report concluded that "Notably, cord blood analysis revealed no detectable IgE to peanut indicating in utero exposure was not likely to account for the sensitization. Of further note, maternal dietary factors also had no correlation with peanut allergy. However, there was an association between the duration of breastfeeding and peanut allergy; the significance of this is unclear."

But on the other hand, the study revealed that "there was a strong and statistically significant association between consumption of soy milk or soy formula in the first two years of life and the development of peanut allergy. This consumption typically preceded development of peanut allergy. The association with soy protein exposure and peanut allergy could arise from cross sensitization through common episodes that may prime T cell responses."

Milk allergy was not associated with peanut allergy nor was the use of breast creams, often containing trace elements of peanut oil was also ruled out. But some creams for rashes also contain peanut oil and researchers found that the use of these types of creams was suspect in causing the allergy.

The mystery has yet to be solved. The peanut is actually not a true nut, but a member of the legume family, which includes peas, lentils, soybeans and lima beans. Having a peanut allergy doesn't necessarily mean a person will be allergic to other legumes or nuts because of the varying sensitivity level of the individual to the peanut protein found in different types of nuts and legumes.

So far, after-the-fact treatment of the allergy and avoiding the nut, or traces of the nut in the production of other products is still the best approach in prevention. But the results of this study is promising. But whatever you do, don't try any home treatments not recommended by your child's doctor. But rest assured, the answer to this childhood problem seems close.
