Legume allergies more in children with multiple food allergies

Legume allergies seemed more common among children with multiple food allergies, and a maximum of those children had been allergic to multiple legumes, according to a study performed in Turkey and published in Pediatric Allergy and Immunology.

Also, lip dose challenges (LDCs) with paste seem promising in predicting oral food challenge outcomes, Elif Soyak Aytekin, MD, of the branch of pediatric immunology at Hacettepe University Faculty of Medicine in Ankara, Turkey, and associates wrote in the study. The observe tested 87 kids (median age, 4.9 years; 78% boys; median age at hypersensitivity onset, 19 months) observed for legume allergy in the pediatric allergy department at Hacettepe University Ihsan Dogramaci Children’s Hospital between Jan. 1, 2015, and Sept. 30, 2021. The population included 78 kids (90%) with a record of atopic comorbidity, inclusive of 70% with atopic dermatitis, 40% with asthma, and 30% with allergic rhinitis. Also, 92% had been allergic to 2 or more food groups, inclusive of 71% to tree nuts, 67% to hen’s egg, 49% to cow’s milk, and 46% to seeds. Lentil (66%) turned into the maximum often recognized legume food allergies, observed through peanut (61%), chickpea (28%), pea (24%), bean (8%), and soybean (1%), with 60% of children experiencing multiple legume food allergies.

According to the researchers, LDC had an 81.82% diagnostic accuracy, 72.22% sensitivity, 93.33% specificity, 92.86% positive predictive value, 73.68% negative predictive value, 10.8 positive probability ratio, and 0.3 negative likelihood ratio. Although considered the gold standard for diagnosis, the researchers said, OFC has risks and may be each labor and time-consuming. But the standardized use of LDC paste, they continued, should become aware of sufferers at risk for more severe reactions and reduce the number of OFCs needed.

This study has confirmed the information of other studies regarding the potency of beans regarding allergy. Other researches on this topic have found that:

  • Peanut is a bean, however, most people with peanut hypersensitivity (about 95%) tolerate different beans.
  • If a person is allergic to “other beans,” the triggers are normally amongst chickpea, lentil, green pea (and its varietals), and soy, and not common for string bean, white bean, lima, kidney, or black bean.
  • If someone is displaying hypersensitivity to a few beans many of the ones listed as “usually” above, then hypersensitivity to a couple of amongst them is likewise possible. People with broader ranges of food hypersensitive reactions are much more likely to see this happen.
  • It is likewise possible to be allergic to 1 type of bean and no others, along with just lentil or just peanut.
  • The quantity of bean eaten, or how it is processed, can also additionally have an effect on hypersensitivity. Some humans can also additionally tolerate tofu and different soy products, however “soy protein isolate” or “soy protein concentrate” may over-represent certain proteins in which the individual does react.
