Accurate prediction of tolerance to processed allergens with skin prick tests and sIgE levels remains largely elusive. Food allergy management strategies, especially with milk and egg, have capitalized on the decreased allergenicity of baking. Many milk- and egg-allergic patients tolerate baked and heated forms of these allergens, and the use of these processed foods in oral immunotherapy (OIT) continues to be extensively investigated. Heat is also well recognized to reduce allergic symptoms from some fruits and vegetables in food-pollen syndrome.

The application of food processing to food allergy treatments remains largely unexplored by large clinical studies and provides a key avenue for future research.

In addition to this, bronchial challenge is considered the confirmatory diagnosis, but it is complex to perform. This also occurs in diagnosis of occupational asthma, such as in baker's asthma, in which we have investigated a reliable marker to avoid the bronchial challenge.

Preliminary data from the NAVIGATOR trial indicate that tezepelumab may reduce CRSwNP symptoms in patients with comorbid asthma. While further research is required to clarify the extent of TSLP contribution in CRSwNP, this review highlights the potential of anti-TSLP therapies as a novel approach for managing severe, uncontrolled CRSwNP.
