Is your child allergic to eggs?

Children WANTED! The Murdoch Children’s Research Institute (MCRI) is running a trial to test pioneering allergy treatment for those kids who are allergic to hen eggs.

Trial at a Glance:

  • A trial led by the Murdoch Children’s Research Institute is recruiting 80 egg allergic children and adolescents, aged five to 17 years, to test a pioneering new approach to food allergies
  • A probiotic and peanut immunotherapy treatment, which has shown long-lasting effects against peanut allergy, is now being extended to egg. Eggs are a major trigger of childhood allergy worldwide
  • If the approach is also effective in treating egg allergies, treatment could extend to other food allergies
  • The trial led by the Institute is recruiting 80 children and adolescents allergic to egg to test a pioneering new approach to food allergies.

MCRI Professor Mimi Tang is developing a probiotic and peanut immunotherapy treatment, which has shown longlasting effects against peanut allergy. Prof Tang is now extending that treatment approach to egg, a major cause of childhood allergy worldwide.

Recorded incidences of food allergy have risen dramatically in recent decades

Prof Tang is calling on families with children aged five to 17 years who are allergic to hen eggs to take part in the new PEAT trial.

“Food allergies affect around 5-6 per cent of all children and 10 per cent of infants,” Professor Tang said. “And egg allergy is one of the most common food allergies in childhood, affecting almost 9 per cent of babies in Australia and up to 2.5 per cent of children worldwide.

“We previously thought that most children with egg allergy would develop tolerance by school age, but recent studies show that egg allergy can persist in a significant number of children until adolescence.”

Professor Tang said most people with egg allergy have no choice but to avoid all foods containing eggs. “Because eggs are a common cooking ingredient, accidental ingestion is common, causing frequent and sometimes life-threatening reactions,” she said.

“To live with food allergy reduces your quality of life. Every day you need to be vigilant against the threat of a serious reaction. Deaths are very rare, but patients and families are understandably fearful of this possibility.”

Peanut Allergy Trial pioneered this approach

In a 2015 clinical trial testing the probiotic and peanut oral immunotherapy (PPOIT) treatment, participants were given a probiotic together with peanut protein in increasing amounts once daily for 18 months. More than 80 per cent of children who received the PPOIT treatment were able to tolerate peanuts at the end of the trial and the majority were still tolerating peanut four years on.

“If we can show that the probiotic food immunotherapy approach is effective in treating egg allergies as well, this will mean that we could perhaps extend treatment to other food allergies,” Professor Tang said.

“We are fortunate to have received funding from Australia’s National Health and Medical Research Council to conduct a randomised controlled trial to test the effectiveness of a probiotic egg oral immunotherapy for the treatment of egg allergy.”

Recorded incidences of food allergy have risen dramatically in recent decades with 250 million people worldwide now suffering a food allergy. Hospital admissions for severe allergic reactions have doubled over the last decade in Australia, US and UK. In Australia, admissions for serious food allergy reactions in children aged zero to four years have jumped to an even greater extent, increasing five-fold over the same period.

For this study, the children will be randomly allocated into one of two groups. Half the children will go into an active group (probiotic and egg oral immunotherapy) and half will go into a placebo group. At home the child will take a dose of probiotic (or placebo) and a dose of egg powder (or placebo) once a day for a total of 18 months.

Professor Tang is running this egg trial in conjunction with the National University Hospital in Singapore. Researchers from James Cook University will also contribute to the study.
