At London Allergy and Immunology Centre, we closely monitor emerging research to ensure our patients benefit from the most up-to-date, evidence-based allergy care.

What Is Baked Milk Oral Immunotherapy (BMOIT)?

Oral immunotherapy (OIT) is a treatment approach designed to desensitise the immune system by exposing patients to very small, gradually increasing amounts of an allergen under specialist supervision.

Baked milk oral immunotherapy (BMOIT) helps children with cow’s milk allergy build tolerance safely, guided by a UK allergy consultant, with immune system changes and improved quality of life

Baked milk OIT differs from traditional milk OIT because it uses milk that has been extensively heated, such as milk baked into muffins or cakes. Heating changes the structure of milk proteins, making them less allergenic while still capable of training the immune system to tolerate milk.

Many children with cow’s milk allergy can already tolerate baked milk, even if they react to fresh milk. This makes baked milk an attractive starting point for immunotherapy.

Key Findings From the January 2025 Study

The study, titled “Clinical and immunological outcomes after randomized trial of baked milk oral immunotherapy for milk allergy”, followed children aged 3 to 18 years with confirmed cow’s milk allergy.

• Baked milk OIT was well tolerated, with most reactions being mild
• 70% of participants achieved desensitisation to baked milk
• 37% also developed tolerance to unheated (fresh) milk
• No severe allergic reactions were reported during treatment

These findings suggest that baked milk oral immunotherapy may safely increase milk tolerance while reducing the risks often associated with traditional milk OIT.

How Does Baked Milk OIT Affect the Immune System?

In addition to clinical outcomes, researchers analysed immune markers to understand how tolerance develops during baked milk OIT.

• Reduction in milk-specific IgE antibodies, which trigger allergic reactions
• Increase in IgG4 antibodies, associated with immune tolerance
• Favourable changes in immune cells involved in regulating allergic inflammation

These immunological changes confirm that baked milk OIT actively modifies the allergic immune response rather than simply masking symptoms.

Why This Research Matters for Families

Living with cow’s milk allergy can lead to anxiety about accidental exposure, nutritional concerns, and social challenges at school, childcare, and family events.

Baked milk oral immunotherapy may help by:

• Increasing safety margins against accidental milk exposure
• Expanding dietary options
• Improving quality of life for children and their families

While not every patient is suitable for oral immunotherapy, this approach offers new hope for carefully selected individuals.

Is Baked Milk Oral Immunotherapy Available?

Baked milk oral immunotherapy should only be performed under specialist medical supervision. It is not suitable for all patients with cow’s milk allergy and requires careful assessment, monitoring, and long-term follow-up.

At London Allergy and Immunology Centre, we assess each patient individually to determine whether oral immunotherapy, including baked milk protocols, is appropriate and safe.
