CONCLUSIONS: Both animal models showed comparable results on the residual allergenicity of partial hydrolyzed whey proteins, but none of the centers was able to differentiate between the residual sensitizing capacities of the pWH-B and -C based on a single elicitation parameter in the murine model. Differences in microbiota composition might contribute to the robustness of the food allergy murine model. For a well-balanced prediction on the potential allergenicity of hydrolyzed infant formulas a multiple murine parameter model is suggested to decrease the risk of false positive or false negative results. A future challenge...

Authors: Chang C, Wu H, Lu Q Abstract Food allergy is a global health problem, particularly in developed countries. It is mainly mediated by Th2 cell and IgE produced by B cells. While the pathogenesis of IgE-mediated food allergy is quite straightforward, the factors that lead to the development of food allergies at any age in children and adults are unclear. Recent studies have revealed that genetics, epigenetics, and environmental exposures contribute to the development of atopy. In this chapter, we discuss the interplay between these three key elements, reveal how epigenetic modifications may mediate genetic su...

Abstract Food allergy affects up to 10% of the population. The identification of modifiable risk factors including skin barrier dysfunction, vitamin D deficiency, microbiome, and route and timing of allergen exposure is leading to effective prevention strategies, and some of which are now included in public health guidelines. An increasing understanding of the pathophysiology has improved diagnostic options and revealed novel manifestations such as delayed anaphylaxis to mammalian meat related to sensitization to a sugar moiety triggered by tick bites. Current diagnosis has improved with the commercialization of a...

CONCLUSIONS: Lcr35 treatment during OIT had some synergic effect for protection against anaphylaxis in a mice model of egg allergy. These findings should be confirmed in future animal studies including more detailed immunological profiles and human studies. PMID: 32400134 [PubMed]

ConclusionA multidisciplinary approach to the treatment of sinonasal symptoms using both escalation of medical therapy and surgical approaches may improve QOL of patients with suspected MCAS. Consensus criteria for MCAS, which includes elevation in tryptase over baseline during an episode, may exclude the full spectrum of individuals with MCAS from potentially beneficial treatment.

We examined the gut microbiota alterations in patients with WDEIA and the microbiota's association with WDEIA. Fecal samples were collected from 25 patients with WDEIA and 25 healthy controls. Environmental exposure factors were obtained, serum total IgE, IgE specific to wheat, gluten, and ω-5 gliadin were measured. Fecal samples were profiled using 16S rRNA gene sequencing. The relative abundances of the bacterial genera Blautia (P
