Although our study is limited by a small sample of cases, there is an inclination for predicting the outcome of a sesame food challenge with SPT based on our results



Quote
Notably, 29% of sesame allergic patients had a sesame-specific IgE < 0.35 kUA/L. This is in contrast to the findings of Zavalkoff et al. who reported a cut-off < 0.35 kUA/L as being useful in excluding a diagnosis of sesame allergy.

This is from 2003 ... I'm not sure if there has been more research since then.  Not a big sample size for sesame.


"Thresholds of clinical reactivity to milk, egg, peanut and sesame in immunoglobulin E-dependent allergies: evaluation by double-blind or single-blind placebo-controlled oral challenges."

http://www.ncbi.nlm.nih.gov/pubmed/12911777

Quote
Data from 125 positive oral challenges to egg, 103 to peanut, 59 to milk and 12 to sesame seeds were analysed. Haemodynamic modifications were observed in 2%, 3%, 1.7%, and 8% of the oral challenges (OCs) to egg, peanut, milk and sesame, respectively. Respiratory symptoms were observed in 12%, 20%, 10% and 42% of egg, peanut milk and sesame allergies, respectively. A cumulative reactive dose inferior or equal to 65 mg of solid food or 0.8 mL of milk characterized 16%, 18%, 5% and 8% of egg, peanut, milk and sesame allergies, respectively. 0.8% of egg allergies, 3.9% of peanut allergies, and 1.7% of milk allergies reacted to 10 mg or less of solid food or to 0.1 mL for milk. The lowest reactive threshold has been observed at less than 2 mg of egg; 5 mg of peanut, 0.1 mL of milk and 30 mg of sesame seed. Ten out of 29 OC with peanut oil, two out of two OC with soy oil and three out of six OC with sunflower oil were positive. Five out six OC with sesame oil were positive: 1 and 5 mL induced an anaphylactic shock.

"Sesame allergy: a growing food allergy of global proportions?"
http://www.ncbi.nlm.nih.gov/pubmed/16095135

Quote
Evidence was found for increased reporting of sesame allergy during the past 5 decades, with reports mostly from developed countries. Clinically, most sesame allergy was presented in at least 2 major forms: (1) immediate hypersensitivity, often expressed as systemic anaphylaxis, associated with positive skin prick test and/or IgE antibody test results to sesame proteins with some cross-reactivity with other foods, and (2) delayed hypersensitivity to lignin-like compounds in sesame oil clinically expressed as contact allergic dermatitis. There were a few cases of immediate hypersensitivity to sesame with negative skin prick test and/or IgE antibody test results that were confirmed by oral challenge tests.

"Oleosines in sesame allergy"
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3723685/
Quote
Oleosins have been described by others [2], and are important allergens from sesame seed. Since they are hydrophobic, they are not present at commercial extracts or extract prepared from sesame seed in saline, or the CAP system extract.

sesame seed study.

"Clinical Characteristics Of - And Predictive Diagnostic Factors For - Sesame Seed Allergy In
Food-Allergic Children"

Quote
a significant proportion of sesame-seed-allergic children were able to tolerate low amounts of sesame ingestion. This seems to be a common clinical finding in sesame allergy, perhaps reflecting peculiarities of sesame allergens and digestive processing thereof.


Quote
tolerance of loose seeds does not always confirm tolerance of sesame concentrates




Just a reminder .... sesame-allergic people should strictly avoid all sesame, including cross-contamination, unless their allergist tells them otherwise.

sesame allergy patient study uk


"Sesame allergy in Britain: a questionnaire survey of members of the Anaphylaxis Campaign."
http://www.ncbi.nlm.nih.gov/pubmed/15787876
Quote
Sesame should be identified clearly as an ingredient and separately from nuts and peanuts when it may be an allergen contaminant. People at potential risk need clear allergy diagnosis and informed guidance to enable them to avoid this key allergen more easily.

"Cross reactivity of seed allergens"
http://www.aaaai.org/ask-the-expert/cross-reactivity-seed.aspx?utm_content=buffer77698&utm_medium=social&utm_source=linkedin.com&utm_campaign=buffer

Quote
I think your summary of the literature suggesting that we do not have a great deal of detail on the cross reactivity of ingested seeds is a fair assessment. The 2S, 7S, 11S storage proteins are common to many seeds and could provide cross reactivity. However, the clinical evidence of the importance of this cross-reactivity is not well substantiated.
