Predictive values of alpha‐gal IgE levels and alpha‐gal IgE: Total IgE ratio and oral food challenge‐proven meat allergy in a population with a high prevalence of reported red meat allergy

Pediatric Allergy and Immunology, 2018
Severe meat allergy with anaphylaxis may be caused by sensitization to alpha‐gal. Levels of alpha‐gal sensitization that correlate with high risk of meat allergy are currently unknown.

Low‐dose oral food challenges

Pediatric Allergy and Immunology
Abstract Background Infants aged <1 year with confirmed food allergies generally need to avoid causative foods completely for a certain period. Low‐dose oral food challenges (LD‐OFCs) may be an effective strategy for safely introducing small amounts of causative foods to individuals with ...

Diagnostic oral food challenges: Procedures and biomarkers

Journal of Immunological Methods, 2012
Oral food challenge (OFC) is the gold standard for the diagnosis of food allergy. They are conducted to confirm whether an allergy to food exists (initial challenge) or to monitor for resolution of a food allergy. The history of an immediate allergic reaction, when supported by positive tests for specific IgE antibodies to the suspect food, is often ...

Home Introduction of Baked Egg After Oral Food Challenge

The Journal of Allergy and Clinical Immunology: In Practice, 2022
Baked egg (BE) introduction may accelerate resolution of egg allergy. Long-term data regarding the safety and success of BE introduction in the real world are limited.To identify predictors of future egg consumption and barriers to advancement based on characteristics during and after BE oral food challenges (OFCs).We performed a retrospective review ...

Oral food challenges in children in Italy

Allergy, 2005
Background:  Epidemiological surveys identify a 900 000‐strong potential paediatric population who may self‐report with food allergy in Italy. As the reference test is the double‐blind, placebo‐controlled food challenge for diagnosis, we carried out a nation‐wide questionnaire survey of hospital‐based paediatric allergy centres between 1 January and 30

Work Group report: Oral food challenge testing

Journal of Allergy and Clinical Immunology, 2009
Oral food challenges are procedures conducted by allergists/immunologists to make an accurate diagnosis of immediate, and occasionally delayed, adverse reactions to foods. The timing of the challenge is carefully chosen based on the individual patient history and the results of skin prick tests and food specific serum IgE values.

Food protein‐induced enterocolitis syndrome: Current practices in oral food challenge

Allergy and Asthma Proceedings, 2021
Background: Oral food challenges (OFC) in food protein‐induced enterocolitis syndrome (FPIES) are performed to confirm a diagnosis, test for development of tolerance, and find safe alternatives. Objective: We aimed to define OFC outcomes and identify safer test strategies.

Biphasic reactions in children undergoing oral food challenges

Allergy and Asthma Proceedings, 2012
Literature regarding biphasic reactions in the pediatric population is sparse. We aimed to determine the prevalence of biphasic reactions in children with food allergies undergoing oral food challenges (OFCs) and examine whether any clinical or treatment factors are associated with biphasic reactions.

Oral food challenge using different target doses and time intervals between doses

Current Opinion in Allergy and Clinical Immunology, 2018
Purpose of review The oral food challenge (OFC) is a specific and vital tool used in clinical practice to identify the level of tolerance a person exhibits toward certain foods while diagnosing food-related allergies.
