Anaphylaxis to cow's milk and beef meat proteins
1Department of Pediatrics, University of Geneva School of Medicine, Geneva, Switzerland. Phillippe.Eigenmann@hcuge.ch
Summary
Anaphylaxis to cow's milk and beef is increasingly recognized. Diagnosis involves allergy testing, and avoidance is key, though research into prevention and treatment continues.
Area of Science:
- Immunology
- Allergy Research
- Food Science
Background:
- Cow's milk allergy is a well-established cause of food allergy.
- Beef is emerging as a significant cause of immunoglobulin (Ig)E-mediated reactions.
- Anaphylaxis to these bovine proteins affects both children and adults.
Purpose of the Study:
- To review anaphylactic reactions to cow's milk and beef.
- To summarize current understanding of diagnosis and management.
- To highlight ongoing research in prevention and treatment.
Main Methods:
- Literature review of PubMed articles.
- Critical analysis of relevant publications.
- Expert opinion for data selection.
Main Results:
- Cow's milk allergy prevalence is 1-2%; beef allergy data is limited.
- Anaphylaxis presentation is similar for both foods.
- Diagnosis relies on skin prick tests and specific IgE antibody measurements, with food challenges in select cases.
Conclusions:
- Strict dietary avoidance of cow's milk and beef is crucial for patients with anaphylaxis.
- Cow's milk allergy often has a good prognosis, with many children outgrowing it.
- Research is actively exploring novel prevention and treatment strategies for food allergies.
