Recently, published in the Journal of Pediatrics alliance and immunology, researchers from the National Institutes of health found that sesame allergy is very common in children with other food allergies, accounting for an estimated 17% of the above population In addition, scientists have found that sesame antibody test (its usefulness has been controversial) can accurately predict whether children with food allergy are allergic to sesame In the prediction of sesame allergic reaction, there is no uniform standard for the standard allergy test (http:// (skin prick test and allergen specific antibody test) In response, Dr Pamela a frischmeyer guerrerio, deputy director of NIAID allergic disease laboratory and director of food allergy research department, evaluated 119 children who showed food allergy in sesame antibody test by different methods The researchers tested the children in the study on oral food - the gold standard for diagnosing food allergies - by gradually increasing the intake of sesame seeds under medical supervision and looking for allergic reactions Scientists found that 15 (13%) of 119 children were allergic to sesame, 73 (61%) were tolerant to sesame, and 31 (26%) could not determine their allergic status, mainly because they refused the oral food test Among the 88 children who showed sesame allergy, 17% of them had sesame allergy The scientists measured the levels of antibodies called sesame specific immunoglobulin E (SiGe) in the blood of the 88 children Using data and information about children's allergic state to sesame, researchers developed a mathematical model to predict the possibility of children with food allergy to sesame According to the model, children with SiGe over 29.4kg per liter of serum are more than 50% more likely to be allergic to sesame However, this model needs to be validated by other studies before it can be used in clinical practice
