By South Bay Allergy and Asthma Group
At South Bay Allergy and Asthma Group, we are committed to providing evidence-based care for patients of all ages who suffer from allergies, asthma, and immunologic conditions. One of the most promising areas of research in recent years is the prevention of food allergies by introducing allergens early in infancy. Alongside proactive oral immunotherapy and medications like Xolair® (omalizumab), we are transforming the way allergies are managed—offering hope and improved quality of life for families across the Bay Area.
Why Early Allergen Introduction Matters
Food allergies affect approximately 1 in 13 children in the United States. In the past, it was recommended to delaying the introduction of common food allergens like peanuts, eggs, or dairy. However, recent studies—most notably the LEAP (Learning Early About Peanut Allergy) trial—have flipped this thinking.
The LEAP Study and Its Impact
The LEAP study found that introducing peanuts to high-risk infants between 4–11 months of age reduced the likelihood of developing a peanut allergy by over 80%. This has led to updated guidelines from the American Academy of Pediatrics and the National Institute of Allergy and Infectious Diseases encouraging early introduction of allergenic foods, particularly for children at risk due to eczema or a family history of allergies.
The Role of Oral Immunotherapy (OIT)
Oral Immunotherapy is a breakthrough approach where patients consume tiny, gradually increasing amounts of an allergenic food under medical supervision. This method helps desensitize the immune system, reducing the severity of allergic reactions and, protec the patient from bite size reactions.
Benefits of OIT for Children:
- Improves food tolerance
- Reduces risk of severe reactions from accidental exposure
- Can be started in early childhood (sometimes as early as 6 months)
- Empowers families and reduces anxiety
At South Bay Allergy and Asthma Group, our board-certified allergists offer OIT protocols tailored to your child’s unique needs, ensuring close monitoring and support throughout the journey.
What About Older Children and Adults? Xolair May Help
For older children, teens, and adults with food allergies, Xolair (omalizumab) offers a powerful alternative. Originally approved for allergic asthma, Xolair is now FDA-approved for food allergy treatment when used in conjunction with OIT or as a stand-alone therapy.
How Xolair Works:
Xolair binds to and reduces levels of free IgE (the antibody responsible for allergic reactions), making the immune system less reactive to allergens.
Who Can Benefit:
- Patients with multiple or severe food allergies
- Individuals with uncontrolled asthma despite inhalers
- Those unable to undergo OIT
Frequently Asked Questions (FAQ)
Q: At what age should I introduce common allergens like peanuts or eggs to my infant?
A: If your baby is at high risk for allergies (due to eczema or egg allergy), you can introduce allergens like peanut between 4 to 6 months of age. Always consult with your pediatrician or allergist before doing so.
Q: Is oral immunotherapy safe?
A: Yes, when supervised by experienced allergists, OIT is generally safe and effective. Side effects are usually mild and include symptoms like mouth itching or mild stomach discomfort. Patients are closely monitored during each step of the process.
Q: Can OIT cure food allergies?
A: OIT doesn’t “cure” allergies but increases tolerance to allergens and reduces the risk of severe reactions.
Q: What are the risks of delaying allergen introduction?
A: Delaying allergen exposure beyond 12 months of age—especially in high-risk infants—may increase the chance of developing a food allergy. Early introduction offers protective benefits.
Q: What is the cost of OIT or Xolair treatment?
A: Insurance coverage varies, we can provide the appropriate billing codes for you to verify with your insurance. Our staff will help obtain insurance authorization for Xolair.
