Diagnostic accuracy, risk assessment, and cost‐effectiveness of component‐resolved diagnostics for food allergy: a systematic review.

BACKGROUND: Component-resolved diagnostics (CRD) are promising tools for diagnosing food allergy, offering the potential to determine specific phenotypes and to develop patient-tailored risk profiles. Nevertheless, the diagnostic accuracy of these tests varies across studies; thus, their clinical utility remains unclear. Therefore, we synthesized the evidence from studies investigating the diagnostic accuracy, risk assessment ability, and […]

Risk Factors and Clinical Features in Cashew Nut Oral Food Challenges.

BACKGROUND: Cashew nuts (CN) are capable of causing severe allergic reactions. However, little has been reported about the details of CN oral food challenges (OFC). METHODS: CN-specific IgE (sIgE) levels were measured for 1 year in 66 patients who underwent an OFC with >3 g CN for diagnosis or confirmation of tolerance acquisition between June […]

Prediction of the severity of allergic reactions to foods.

BACKGROUND: There is currently considerable uncertainty regarding what the predictors of the severity of diagnostic or accidental food allergic reactions are, and to what extent the severity of such reactions can be predicted. OBJECTIVE: To identify predictors for the severity of diagnostic and accidental food allergic reactions and to quantify their impact. METHODS: The study […]

Component resolved diagnostics demonstrates that most peanut allergic individuals could potentially introduce tree nuts to their diet.

BACKGROUND: Nut allergy varies from pollen cross-allergy, to primary severe allergy with life-threatening symptoms. The screening of IgE antibodies to a wide spectrum of allergens, including species-specific and cross-reactive allergens, is made possible via microarray analysis. OBJECTIVE: We sought to study the association of variable IgE sensitization profiles to clinical response in peanut-challenged children and […]

Thermal processing effects on the IgE-reactivity of cashew and pistachio.

Thermal processing can modify the structure and function of food proteins and may alter their allergenicity. This work aimed to elucidate the influence of moist thermal treatments on the IgE-reactivity of cashew and pistachio. IgE-western blot and IgE-ELISA were complemented by Skin Prick Testing (SPT) and mediator release assay to determine the IgE cross-linking capability […]

With tree nut sensitization, take the current when it serves, or lose our ventures.

Tree nut allergy affects approximately 1.4-2.3%, depending on the study methodology, patient age, and region in which the study was conducted. Tree nut allergy can be severe, and tends to persist throughout life. Tree nut is not a singular allergen like the other allergens-we use the term "tree nut" to refer to these items, but in essence it can refer to […]

The longitudinal impact of probiotic and peanut oral immunotherapy on health‐related quality of life.

BACKGROUND: We previously reported that probiotic and peanut oral immunotherapy (PPOIT) was effective at inducing sustained unresponsiveness compared with placebo in a double-blind, placebo-controlled randomized trial. This study evaluated the impact of PPOIT on health-related quality of life (HRQL). METHOD: Fifty-one participants (PPOIT 24; placebo 27) from the PPOIT trial completed Food Allergy Quality of […]

Early Introduction of Allergenic Foods for the Prevention of Food Allergy from an Asian Perspective–An APAPARI Consensus Statement.

Emerging evidence for the early introduction of allergenic foods for the prevention of food allergies, such as peanut allergy in Western populations, has led to the recent publication of guidelines in the USA and Europe recommending early peanut introduction for high-risk infants with severe eczema or egg allergy. Peanut allergy is, however, much less prevalent […]

Effect of Varying Doses of Epicutaneous Immunotherapy vs Placebo on Reaction to Peanut Protein Exposure Among Patients With Peanut Sensitivity: A Randomized Clinical Trial.

IMPORTANCE: Epicutaneous immunotherapy may have potential for treating peanut allergy but has been assessed only in preclinical and early human trials. OBJECTIVE: To determine the optimal dose, adverse events (AEs), and efficacy of a peanut patch for peanut allergy treatment. DESIGN, SETTING, AND PARTICIPANTS: Phase 2b double-blind, placebo-controlled, dose-ranging trial of a peanut patch in […]
