Trial Summary

What is the purpose of this trial?

Background: Atopic dermatitis (AD), also called eczema, makes skin dry, red, and itchy. People with AD are more likely to get a food allergy than people without AD. But some food allergy tests are not always accurate in people with AD. Researchers want to study if people are truly allergic to milk and/or peanuts. Objectives: To improve the ways doctors test for food allergy in people with AD. Eligibility: People ages 3 21 who have had AD; have a high total IgE level (an allergic antibody); might have a milk and/or peanut allergy; and are currently enrolled in another NIH study Design: Participants will be screened under another protocol. Participants will have a physical exam, blood tests, and medical history. Participants will breathe into a plastic device that measures lung strength. Participants may get a small plastic tube inserted in their arm. Participants who have not had an allergic reaction to food in the past 3 years will do 1 or more oral food challenge (OFCs) depending on their allergies. They will eat a little bit of the food they might be allergic to. They will be watched for a reaction. If they have one, they will know for sure they are allergic. They may keep eating bigger portions of the food until they either have a reaction or finish all the food. In some OFCs, participants will get a placebo food. OFCs will last a few hours or 2 days. Participants will repeat all tests at each OFC. Participation can last up to 12 months. ...

Will I have to stop taking my current medications?

You may need to stop taking certain medications like omalizumab or dupilumab at least 6 months before a food challenge, and you might need to stop antihistamines and oral steroids before the challenge as well. However, you can continue using topical steroids.

What data supports the effectiveness of the treatment Baked milk and Rice milk (placebo for Baked milk), Baked milk, Heated milk, Rice milk (as placebo), Dry Milk Powder and Corn Starch (placebo for Milk powder), Dry Milk Powder, Milk Powder, Corn Starch (placebo), Peanut flour and Oat flour (placebo for peanut flour), peanut flour, oat flour (placebo), Peanut powder and Oat flour, Peanut powder: Arachis hypogaea, Groundnut powder; Oat flour: Avena sativa flour for food allergy?

Research shows that many children with cow's milk allergy can tolerate baked milk, which may help them eventually tolerate regular milk. Introducing baked milk gradually can speed up the resolution of milk allergies in some children.12345

Is there safety data for IgE Threshold Testing for Food Allergy treatments like Baked milk, Rice milk, and Peanut flour?

Research shows that peanut allergen powder used in oral immunotherapy has been evaluated for safety in clinical trials, indicating it is generally safe for use in humans. However, hypoallergenic milk substitutes may contain aflatoxin, a potential contaminant, so control measures should be in place to ensure safety.678910

How does IgE Threshold Testing for Food Allergy differ from other treatments for food allergies?

IgE Threshold Testing for Food Allergy is unique because it focuses on determining the specific level of IgE antibodies (immune system proteins that react to allergens) that trigger allergic reactions, which can help tailor dietary recommendations and predict safe food consumption, unlike standard treatments that often involve complete avoidance of allergens.18111213

Interventions

  • Baked milk and Rice milk (placebo for Baked milk) (Other)
  • Dry Milk Powder and Corn Starch (placebo for Milk powder) (Other)
  • Peanut flour and Oat flour (placebo for peanut flour) (Other)
  • Peanut powder and Oat flour (Other)
Trial OverviewThe trial tests if participants with eczema are truly allergic to milk or peanuts by giving them increasing amounts of these foods or placebos in controlled settings. The goal is to improve food allergy testing methods.
Participant Groups
4Treatment groups
Experimental Treatment
Group I: Two-Step Open FeedingExperimental Treatment4 Interventions
Participants who consume baked milk, straight milk, and/or peanut products less than once per week but at least once per month will do a two step open oral food challenge.
Group II: Peanut DBPCFCExperimental Treatment2 Interventions
The DBPCFC for peanut allergy will be done with either peanut flour or a placebo (oat flour). The following participants will undergo this DBPCFC: - All participants who eat peanut less than once per month - Participants who never eat peanut On the first day of this challenge, participants will be randomized to either peanut or placebo, and then will be challenged with the other food on the next day.
Group III: One-Step Open FeedingExperimental Treatment4 Interventions
Participants who are consuming baked milk, straight milk, and/or peanut products at least once per week will do a one-step oral food challenge.
Group IV: Milk DBPCFCExperimental Treatment2 Interventions
There are two double blind placebo controlled food challenges. The first challenge is to baked milk. The following participants will undergo this DBPCFC: - All participants who eat baked milk less than once per month. - Participants who never eat baked milk or straight milk. On the first day of this challenge, participants will be randomized to either milk Baked milk or rice milk. Dry milk powder or corn starch. or placebo, and then will be challenged with the other food on the next day.

Findings from Research

Skin prick testing (SPT) with a baked milk (muffin) slurry can effectively predict which milk-allergic children can safely consume baked milk, showing a sensitivity of 100% for those with negative tests.
In a study of 30 children aged 2-16 years, those with a muffin SPT result of less than 3 mm were likely to tolerate baked milk, while the optimal decision point for the test was determined to be 4 mm, indicating its potential utility in clinical practice.
Prospective evaluation of testing with baked milk to predict safe ingestion of baked milk in unheated milk-allergic children.Kwan, A., Asper, M., Lavi, S., et al.[2020]
In a study of 64 children with severe cow's milk allergy, 67.2% tolerated a low-dose baked milk oral food challenge, indicating that baked milk oral immunotherapy (OIT) can be effective for many children.
Desensitization to fresh milk was achieved in 42.2% of the children, particularly those with lower cow's milk-specific IgE levels, although there remains a risk of anaphylactic reactions during the OIT process.
Benefits of baked milk oral immunotherapy in French children with cow's milk allergy.Gruzelle, V., Juchet, A., Martin-Blondel, A., et al.[2021]
In a study of 48 children with IgE-mediated cow's milk allergy, 81% tolerated baked cow's milk when it was incorporated into a wheat matrix (ciambellone), indicating that the wheat matrix significantly aids in tolerance.
The study found that a negative prick-by-prick test (PbP) had a 100% negative predictive value, suggesting that if the test is negative, children can safely consume processed cow's milk without needing an oral food challenge.
