An important and hopeful study from Dr. Vadas, director of allergy and immunology at St. Michael's Hospital...

Here is the news release:

Blood test identifies people with life threatening allergies

TORONTO, Ont., January 3, 2008 — Almost 20 to 30 percent of the general population has allergies, and for one to two percent of the population their allergic reactions can be life-threatening. In a new study by Dr. Peter Vadas, director of the Division of Allergy and Clinical Immunology at St. Michael’s Hospital, a new blood test will identify those people who are at risk of severe or fatal anaphylactic reactions and potentially save lives.

“This study has shown that patients with low levels of an enzyme known as PAF-AH had severe or fatal anaphylactic reactions to a range of allergic triggers, such as foods, drugs and stinging insects. Patients with normal levels of this protective enzyme had only mild reactions. The study has also identified at new chemical which appears to play a key role in causing the severe and life-threatening manifestations of allergic reactions” says Dr. Peter Vadas.

The study was led by Vadas in Canada’s only anaphylaxis clinic at St. Michael’s Hospital. His body of research covers life threatening allergic reactions, immune system disorders and a focus on what makes people prone to fatal allergies.

Vadas’ latest study appears in the New England Journal of Medicine today (January 3, 2008). The test could save the lives by alerting many people who are currently unaware that their allergies could be fatal.

That is exciting news! I will be so glad when we can move diagnosing out of the dark ages of interpreting bumps and and into the golden age of knowledge.
I was just commenting to our allergist today that it must be frustrating to come from a scientific background and into a field that relies so much on the interprestation of welts and wheals. Very subjective as opposed to objective.

Daughter: asthma, allergies to egg, milk, peanuts, tree nuts, most legumes (not soy and green beans) & penicillin. Developing hayfever type allergies.
Husband: no allergies
Me: Oral Allergy Syndrome, Allergic to Birch trees

It's wonderful to start the year with hopeful news. The holidays are so difficult for people with allergies. Treats are everywhere. There is so much extra work to provide a normal Christmas for allergic children. I am so tired right now and have been really feeling weighed down by food allergies this week. Let's hope that there will be more insight into allergies as a result of this study in the year to come.

13 year old daughter -- lives with life-threatening allergies to milk, tree nuts and peanuts; seasonal allergies (birch, maple, ragweed); pet allergies; asthma; and eczema
10 year old son - no allergies
