Fatal Food Anaphylaxis – registering a rare outcome

Deaths due to food allergy are incredibly rare (1), but it is now understood that food is the most commonly identified trigger of anaphylaxis (2). In the United States, deaths from food anaphylaxis are broadly estimated to occur at a rate of 5-200 cases per year (3).

This study is aimed at determining the characteristics of pediatric patients who experienced anaphylaxis along with treatments administered in order to determine the usefulness of tryptase level assessment as a marker of anaphylaxis in Korean children. A total of 107 patients who were diagnosed with anaphylaxis in a single pediatric emergency center over a 3-year period were included in the study. Patient clinical characteristics, symptoms, signs, allergy history, trigger factors, treatments, and laboratory findings, including serum tryptase levels, were included in the analysis. Food allergies (39.3%) were the most common...

Abstract BACKGROUND: Approximately 8% of children have food allergy. Yet, little is known about how parents cope with the burden of this disease. OBJECTIVE: To describe the perceptions of food allergy-related mental health issues of parents of children with food allergy. METHODS: Parents of children with pediatric allergist-diagnosed food allergy were recruited via allergy clinics and education centres in a large, Canadian city. We used content analysis to identify overarching themes. RESULTS: We interviewed 21 parents with children (boys (13/21; 62.9%) age

We report a case of an 8-year-old boy who developed a cochineal allergy.Current disease history: He has been suffering from atopic dermatitis, bronchial asthma, and food allergies since childhood. At the age of seven, he experienced an unknown anaphylaxis reaction twice. When he was 8 years old, he ate a frankfurter containing hypoallergenic cochineal for the first time; cold sweat, intraoral discomfort, respiratory distress, and urticaria appeared throughout the body. His skin prick tests were positive, with a result of 2+to frankfurter and cochineal dyes (color value 0.1 and 0.01). In the immunoblot assay, binding of IgE...

AbstractPurpose of ReviewIn recent decades, food allergy has become an increasing concern for families, clinicians, and policymakers. This review aims to summarize what is currently known about the epidemiology and population-level burden of IgE-mediated food allergy, including its effects on quality of life.Recent FindingsPrevalence surveys, healthcare utilization data, and findings from longitudinal cohort studies across the globe indicate that food allergy imposes a growing societal burden. Worryingly, recent data indicate that food allergies may be more prevalent among adult populations than previously acknowledged, wi...

CONCLUSION: Tree nut allergy remains an understudied area of food allergy research with limited region specific studies based on robust food allergy measures in population cohorts with longitudinal follow up. This currently limits our understanding of tree nut allergy prognosis. PMID: 32044450 [PubMed - as supplied by publisher]

(CNN) — The US Food and Drug Administration approved the first drug to treat peanut allergies in children on Friday, following an advisory committee vote of approval in September. The drug, Palforzia, can be used for children between 4 and 17 years old. It’s designed to minimize the incidence and severity of a child’s allergic reaction to peanuts, as even a small amount of exposure can be harmful to children with the allergy. Children are left attempting to avoid exposure to peanuts to avoid reactions. Though that will continue to be necessary with Palforzia, the risk of a reaction will be lessened, says ...

Food allergy (FA) is common in the United States. Emerging evidence demonstrates disparities in pediatric FA outcomes in the United States, with Black children at increased risk for FA and fatal anaphylaxis. However, less is known about Hispanic/Latino children with FA, including whether the marked difference in asthma prevalence observed between children of Mexican and Puerto Rican descent —the “Hispanic Paradox”—is also present with respect to FA.

In conclusion, when the OFC is not possible, the SPP test with natural sesame seed may be applicable in patients with a convincing history instead of the artificial or commercial extracts of sesame used for SPT. Positive SPP is a good alternative diagnostic method for patients with sesame anaphylaxis. Also, the poor sensitivity of SPT and sIgE may indicate the poor discriminative capability of these tests.
