Insights
Cow's milk and egg are common food allergens in children with allergic diseases. This study compared diagnostic methods for food allergies, including IgE serum levels and allergy tests.
Area of Science:
- Pediatric Allergy and Immunology
- Clinical Diagnostics
- Gastroenterology
Background:
- Allergic diseases are prevalent in children, with food allergies being a significant concern.
- Common manifestations include atopic dermatitis, asthma, rhinitis, and gastrointestinal issues.
- Identifying specific food triggers is crucial for effective management.
Purpose of the Study:
- To investigate common food allergens in pediatric allergic diseases.
- To compare the efficacy of various laboratory diagnostic methods for food allergies.
- To analyze the diagnostic accuracy of Total IgE, specific IgE, Prick test, and ALCAT test.
Main Methods:
- Study included 14 children (8 months–7 years) with allergic conditions.
- Evaluated Total IgE serum level, specific IgE serum levels, Prick test, and ALCAT test.
- Cow's milk and egg were identified as the most frequent offending foods.
Main Results:
- Cow's milk and egg were identified as the most common food allergens in the studied pediatric population.
- The study analyzed and compared results from Total IgE, specific IgE, Prick, and ALCAT tests.
- Differences in diagnostic performance among these methods were observed.
Conclusions:
- Cow's milk and egg are primary food allergens in children with allergic diseases.
- Multiple diagnostic tools exist for food allergy, each with varying sensitivities and specificities.
- Further comparative analysis is needed to establish optimal diagnostic algorithms for pediatric food allergies.
Abstract:
Fourteen children affected with allergic disease, from 8 months to 7-years-old, were studied; three children had Bronchial asthma, one child Bronchial asthma and rhinitis, one child recurrent laryngospasm, six children atopic dermatitis, two children diarrhoea, one abdominal pain. In all patients cow's milk and egg were the most common offending foods. Total IgE serum level, IgE serum specific, Prick test and ALCAT test (the test predicts food which would produce a problem) were investigated. A comparison among the different laboratory methods for food allergy diagnosis was analyzed.
