I know we have a general news & research area, but I thought it might be nice to start a research thread specifically for sesame.

-------------------------------------------------------------

"Characterizing the relationship between sesame, coconut, and nut allergy in children"
http://onlinelibrary.wiley.com/doi/10.1111/j.1399-3038.2010.00997.x/full

published online: 15 NOV 2010

Sensitization to sesame was more likely in children with positive SPT to peanuts (odds ratio [OR] = 6.7, 95% confidence interval [CI] [2.7–16.8], p < 0.001) and tree nuts (OR = 10.5, 95% CI [4.0–27.7], p < 0.001). Children with histories of both peanut and tree nut reaction were more likely to have a history of sesame reaction (OR = 10.2, 95% CI [2.7–38.7], p < 0.001).

"Sesame and nut allergies may often strike together"
http://wtaq.com/news/articles/2011/jan/13/sesame-and-nut-allergies-may-often-strike-together/#

Dr. Wanda Phipatanakul, of Children's Hospital Boston, and her colleagues studied the medical records of 191 children

Between 13 percent and 15 percent of peanut and tree nut allergic children were actually allergic to sesame

The rate of sesame allergy jumped up to 50 percent for children allergic to both nuts

"Winchester Hospital Allergist Vandana Krishna, MD Highlights Need for Education on Sesame Allergy"
http://www.winchesterhospital.org/community/SitePages/NewDetails.asp?NewsID=7B84B8AB6F714AC1AFDD10A9B7237235

she recommends education specific to sesame should be provided to primary care physicians, parents and day care and school personnel. She also advocates for the food industry being subjected to stricter labeling guidelines on this emerging food allergen.

Nice article ...

"The Allergens to Watch – Sesame to Lentils and More"
http://allergicliving.com/index.php/2010/08/30/the-allergens-to-watch/

Wood adds that sesame is a raw oil, and as a result can be just as allergenic as the seeds themselves.

In the USA, sesame 

can still be hidden as “tahini”, “spices” or “natural flavouring”.

In Canada, the

government agency not only looks at which allergens are the most common, but which ones are mostly likely to produce the most severe reactions

"Food Allergy: Is Sesame Seed the “Middle Eastern Peanut"?"
http://allergynotes.blogspot.com/2011/05/food-allergy-is-sesame-seed-middle.html

Although specific IgE to peanut were higher than for sesame, peanut-induced allergic reactions were mild, in contrary to sesame where anaphylaxis was the only clinical manifestation.

-----------------------------------

http://journals.lww.com/waojournal/Abstract/2011/01000/Food_Allergy_in_Lebanon__Is_Sesame_Seed_the.1.aspx

Recently, sesame has been recognized as an increasingly frequent and potentially severe allergen.

Thank you so much for this!! We should definitely create a linker thread from the research forum to this thread, but I think it is a terrific idea to house individual allergen research like this.
 
So much of the clinical research is becoming allergen-specific. It's really a wealth of information, and I'm so encouraged that the nuances between food allergens are being explored (for example, the conventional wisdom re: which allergen proteins are the "important" ones in egg, milk, and peanut allergy) but it sure makes it a lot denser in this forest. 

Parsing it out like this is very helpful to let us see the individual grove that we happen to be standing in, as we look at all these trees. THANK YOU!!

"Prevalence of challenge-proven IgE-mediated food allergy using population-based sampling and predetermined challenge criteria in infants"

The Journal of Allergy and Clinical Immunology
Volume 127, Issue 3 , Pages 668-676.e2, March 2011

www.jacionline.org/article/S0091-6749(11)00135-7/abstract

Recruitment occurred at childhood immunization sessions in Melbourne, Australia.

Amongst 2848 infants (73% participation rate), the prevalence of any sensitization to peanut was 8.9% (95% CI, 7.9-10.0); raw egg white, 16.5% (95% CI, 15.1-17.9); sesame, 2.5% (95% CI, 2.0-3.1); cow's milk, 5.6% (95% CI, 3.2-8.0); and shellfish, 0.9% (95% CI, 0.6-1.5). The prevalence of challenge-proven peanut allergy was 3.0% (95% CI, 2.4-3.8); raw egg allergy, 8.9% (95% CI, 7.8-10.0); and sesame allergy, 0.8% (95% CI, 0.5-1.1).

"Skin Prick Test Wheal Size Thresholds Identified"

22-Apr-11
 
Elsevier Global Medical News
 
BY SHERRY BOSCHERT

http://www.medconnect.com.sg/tabid/92/s5/Allergy-Immunology/ct1/c40916/Skin-Prick-Test-Wheal-Size-Thresholds-Identified-/Default.aspx

A 9-mm wheal after skin prick testing provided a 95% positive predictive value for egg or peanut allergy in an analysis of data from 5,000 12-month-old infants

71 with sesame challenges. None of the wheal sizes after sesame challenges reached a 95% positive predictive value for allergy, said Dr. Gurrin of the University of Melbourne.

I know this is a more general research article, but I wanted to keep track that sesame was a common allergen that was being challenged.

Outpatient open oral food challenges – feasible and “feed-able”
http://www.aaaai.org/global/latest-research-summaries/Current-JACI-Research/outpatient-open-oral-food-challenges-feasible-an.aspx

reviewed 22 months worth of successive open OFCs performed at a university-based pediatric allergy outpatient clinic (Mount Sinai School of Medicine, New York, NY)

"Food Allergy in Kids Not Being Optimally Diagnosed"
http://www.medscape.com/viewarticle/753505

The survey involved 40,104 children; of these, investigators identified 3339 children with food allergy.

oral food challenge was done in just 15.6% of children

Formal diagnoses were most frequently confirmed by oral food challenge for milk allergy (22.4%), soy (19.2%), peanut (16.1%), wheat (15.5%), shellfish (14.4%), tree nut (12.6%), egg (12.4%), sesame (11.2%), and fin fish (9.1%).
