Key Allergy Gene Discovered

ScienceDaily (Aug. 25, 2008) — Together with colleagues from the Department of Dermatology and Allergy and the Center for Allergy and Environment (ZAUM) of the Technische Universität München, scientists at the Helmholtz Zentrum München have pinpointed a major gene for allergic diseases.

The gene was localized using cutting edge technologies for examining the whole human genome at the Helmholtz Zentrum München.

The newly discovered FCER1A gene encodes the alpha chain of high affinity IgE receptor, which plays a major role in controlling allergic responses. The team of scientists led by Dr. Stephan Weidinger from the Technische Universität München and Dr. Thomas Illig from the Helmholtz Zentrum München found that certain variations of the FCER1A gene decisively influence the production of immunoglobulin E (IgE) antibodies. IgE antibodies are a particular type of antibody that is normally used to protect against parasites. In Western lifestyle countries with less contact, however, elevated IgE levels are associated with allergic disorders.

In genetically susceptible individuals the immune system becomes biased and produces IgE antibodies against harmless agents such as pollen, dust mites or animal hair. These IgE antibodies then work in conjunction with certain cells to get rid of the allergens, a process that gives rise to the symptoms of allergy such as allergic rhinitis (hay fever), atopic dermatitis or asthma.

Study: Kids May Overcome Dairy Allergies Through Baked Goods

This is another study which contradicts the conventional advice of complete abstinence from dairy products. Again, it is a small study and eggs were the focus, but it does raise the question of a slow introduction of dairy to overcome the body’s reaction to cow’s milk protein. The Star-Ledger reports:

Children allergic to eggs or milk may be able to overcome their intolerance if they eat those foods in gradually increasing quantities in baked goods, suggests two of the first studies to test the theory.

The findings, released this week by the Journal of Allergy and Clinical Immunology, runs counter to the current standard of medical care, which considers strict avoidance as the best route to help a child “outgrow” his or her sensitivity. Some doctors made aware of the studies even warned parents not to try and replicate the results at home, stressing both trials were carried out under strict medical supervision.

“My first impulse is that I don’t think this information is ready for prime-time,” said Donald Perlman, a West Orange allergist affiliated with Saint Barnabas Medical Center. “Food allergies can be a fatal problem. It’s a serious business, so if people try to do this on their own, it could spell disaster.”

Other doctors said they were aware that proteins found in some foods associated with allergies can lose their potency under high temperatures. But whether that would be the case with all allergens — especially problematic ones like peanuts — remains unknown, said Leonard Bielory, director of the Asthma and Allergy Research Center at UMDNJ-New Jersey Medical School in Newark.

“Right now, it appears the ‘let them eat cake’ theory applies to the milder allergy proteins like eggs,” he said.

IgE Chart for Dairy Allergy

To accurately assess your level of allergic response to dairy products, ask your doctor to perform an IgE test.

This simple blood test is far more accurate than the RAST tests of the past, and will indicate the specific level of sensitivity in reaction to an allergen, such as cow’s milk protein. Several tests, taken periodically over many months or years, will reveal trends in the immune system response to a particular allergen, and can be an indicator of the longevity of a dairy allergy.

Here is a chart describing Clinical Implications for Specific IgE Levels:

Green Halloween : Dairy-free holiday treats

With Halloween fast approaching, parents of children with milk allergies will appreciate what this website has to offer - an alternative to chocolate and candy that kids will enjoy. From the founder of Green Halloweem, Corey Colwell-Lipson:

In 2006, I took my six-year-old princess and two-year-old fairy (I know…) trick-or-treating. While most of the neighborhood handed out the requisite Tootsie Rolls and M ‘n M’s , a few homes placed non-candy treats like bubbles and stickers in my girls’ pumpkins. I was so thrilled that someone thought outside the candy-box, that while shouting, “Thank You!” at the top of my lungs, I made a note to myself to remember to trick-or-treat at these homes the following year. But after winding through several streets in the dark, I had already forgotten which homes were candy-free. I mentioned to a nearby parent, “Wouldn’t it be great if there were a sign you could place on your door or window that notified trick-or-treaters that their upcoming treat would be healthy?” This way, parents could seek out those homes and turn trick-or-treating into a scavenger hunt – a hunt for treasures rather than treats.
