Peanut Allergy Treatment in Young Kids Proves Highly Successful

Researchers at the University of Virginia Health have successfully conducted a real-world study on peanut oral immunotherapy in children younger than 3, showing that the approach is safe and effective at desensitizing children to peanuts. The study found that 27 out of 30 children who completed the trial were able to consume a "maintenance dose" of 500 mg of peanut protein per day, with 8 of them eventually being able to eat peanuts freely. The study's findings are considered a breakthrough in the treatment of peanut allergies, which affect approximately 2% of all children and are a leading cause of pediatric emergency room visits.

Key Takeaways:

• The study, conducted by researchers at the University of Virginia Health, found that epOIT (Early Peanut Oral Immunotherapy) is safe and effective at desensitizing children to peanuts.
• 27 out of 30 children who completed the trial were able to consume a "maintenance dose" of 500 mg of peanut protein per day.
• 8 of the 27 children were able to eat peanuts freely after completing a formal peanut food challenge in the allergy clinic.
• The study's findings support previous research suggesting that starting peanut oral immunotherapy early can lead to desensitization and protection from an allergic reaction.
• The researchers posit that starting peanut allergic children on epOIT very early in life (average age of 14 months) made them more likely to become desensitized.
• The study was supported by Food Allergy Research and Education (FARE) and had no financial interest in the work.
• The researchers are calling for larger, multicenter clinical trials to advance this potentially game-changing new treatment for peanut allergies in very young children.

Statistics:

• 2% of all children suffer from peanut allergies.
• 70-80% of children with peanut allergies do not outgrow the condition.
• 14 mg of peanut protein per day was the initial dosage given to the trial participants.
• 500 mg of peanut protein per day is the equivalent of about two peanuts.
• 6,000 mg of peanut protein was the challenge dose consumed by 8 children without symptoms.
• 40 Reese's Pieces is equivalent to 3,000 mg of peanut protein.
• 9 children have been able to maintain their desensitization and eat peanuts freely without their allergy returning.
