Egg allergens in toothpaste. Interesting post on the Allergy Insight blog about milk and egg as ingredients in toothpaste. Since toothpastes are classified as cosmetics in the EU, they are not subject to food labelling regulations so milk ingredients might appear as 'lac', ‘colostrum’, ‘lactoferrin’ and ‘lactoperoxidase’ and egg as ‘lysozyme’, none of which are likely to be recognised by milk or egg allergic people.

Research Reports

Late introduction of fish and eggs is associated with increased risk of allergy development Nov 2017
In this small scale study, it was found that exclusive early breastfeeding and introduction of fish and eggs into the diet before 10 months of age was associated with a lower risk of developing allergies. Full text available.

The Role of Baked Egg and Milk in the Diets of Allergic Children Feb 2018 (epub ahead of print)
It is suggested that many children with milk and egg allergy are able to tolerate some amount of baked milk or egg products. Being able to consume these may work to reduce sensitivity (in a similar way to immunotherapy). However, if not previously tolerated, any oral challenge should be carried out within a hospital.

Desensitization to a whole egg by rush oral immunotherapy improves the quality of life of guardians: A multicenter, randomized, parallel-group, delayed-start design study. August 2017
Desensitising children to egg protein (which was very successful) had a significant benefit on the quality of life ratings of their parents/guardians. However, a high proportion (80%) treated with immunotherapy experienced some type of allergic reaction during the study period – which means safety concerns need to be taken very seriously during oral immunotherapy.

Evidence that eating baked egg or milk influences egg or milk allergy resolution: a systematic review. May 2017
There is not much research looking into the theory that eating baked egg or milk leads to quicker resolution of allergy to eggs or milk. This is despite increasing popular belief that eating these products accelerates desensitisation. The authors suggest that trials are needed to compare the resolution rates of baked-tolerant participants who are randomized to either eat or avoid baked egg or milk products.

Upregulation of calprotectin in mild IgE-mediated ovalbumin hypersensitivity. April 2017
Calprotectin (a protein bio-marker for inflammation) can be detected in faeces and is found to have raised levels for individuals with inflammatory bowel disease, such as Crohn’s and ulcerative colitis. This study demonstrated that raised levels of calprotectin may also be associated with IgE food allergies.

Protective effect of Bifidobacterium infantis CGMCC313-2 on ovalbumin-induced airway asthma and β-lactoglobulin-induced intestinal food allergy mouse models. March 2017
This research looked at the influence of a probiotic (Bifidobacterium) on allergic inflammation in response to egg allergens in mice. This probiotic was found to inhibit the production of IgE (important in the allergic response) and to reduce allergic inflammation. This suggests a potential way of reducing allergic responses in humans and warrants further study.

Safety and feasibility of heated egg yolk challenge for children with egg allergies. Feb 2017
This study looked at whether children who are allergic to cooked egg were able to eat cooked egg yolk alone. It was found that, among 919 patients, only 17% reacted when given an oral cooked egg yolk challenge in hospital. This suggests that the majority of children who are allergic to cooked egg, may safely be able to eat egg yolk. Such challenges should be conducted in hospital for safety. This may be a helpful way to increase variety and nutrition in the diets of food allergic children.

Efficacy and safety of high-dose rush oral immunotherapy in persistent egg allergic children: A randomized clinical trial. Jan 2017
Oral immunotherapy is a very time consuming business. This study explored the efficacy of ‘Rush Oral Immunotherapy’ (ROIT) for egg allergy. 32 children underwent an intensive 5-day desensitisation protocol followed by a five month maintenance phase where egg was consumed every 48 hours. 5-day egg ROIT successfully desensitized 94% of the allergic patients.

Safety and Efficacy of Low-Dose Oral Immunotherapy for Hen's Egg Allergy in Children. Jan 2017

Further research evidence to suggest that oral immunotherapy for egg allergy is both safe and effective. Low-dose OIT induced sustained unresponsiveness to 1/32 and 1/2 of a whole egg, with no severe symptoms. To improve food allergies, continuous intake of small amounts of these foods may be as effective as the consumption of larger quantities.

Randomized Controlled Trial of Oral Immunotherapy for Egg Allergy.
December 2016
Another study looking at whether oral immunotherapy can help increase tolerance to food to which an individual is allergic. This study found promising results: half of the participants who received immunotherapy were able to tolerate a small amount off egg protein, compared to none of the participants who received no treatment.
