Insights
Diagnosing cow's milk protein allergy in infants is crucial. This study presents a new algorithm using elimination and provocation food tests to optimize diagnosis and reduce lab tests for young children.
Area of Science:
- Pediatrics
- Allergology
- Immunology
Background:
- Cow's milk protein allergy (CMPA) is a significant health concern in infants.
- Accurate and timely diagnosis is essential for effective management.
- Current diagnostic methods, like oral provocation tests, require medical settings.
Purpose of the Study:
- To develop an optimized algorithm for diagnosing CMPA in children under one year of age.
- To improve diagnostic reliability while minimizing laboratory burden on infants.
- To integrate elimination and provocation food tests into a streamlined diagnostic process.
Main Methods:
- Utilized allergological anamnesis, physical examination, and specific IgE testing.
- Implemented a two-phase elimination and provocation food test (elimination phase, provocation phase).
- Determined appropriate medical setting for oral provocation based on specific IgE levels (<0.7 kU/L or >0.7 kU/L).
Main Results:
- The proposed algorithm integrates clinical assessment with food challenge tests.
- Specific IgE levels guide the setting for oral provocation, ensuring patient safety.
- Clinical case studies demonstrated the efficacy of the diagnostic approach.
Conclusions:
- A comprehensive diagnostic strategy, including history, diet diaries, and elimination diets, optimizes CMPA diagnosis.
- The elaborated method for diagnosing CMPA in infants is suitable for clinical practice.
- This approach enhances diagnostic accuracy and patient tolerance assessment.
Abstract:
Cow's milk protein allergy is an urgent problem in young children. Early diagnostics and formation of therapeutic tactics are the basic priorities in allergy treatment among young children. Oral provocation tests, which can be performed only in medical establishments, are a golden standard for diagnosing food allergy. Active search continues for optimal scheme of diagnosing cow's milk protein allergy in children in the first year of life. The aim of our research was to create the algorithm of diagnosing cow's milk protein allergy in children younger than one year of age, which will optimize obtaining reliable data on a patient's condition and decrease a load of laboratory examinations on young children using elimination and provocation food test. To complete the set goal, a record of allergological anamnesis, examination, assessment of physical condition and determination of specific IgE to cow's milk proteins were conducted to diagnose cow's milk protein allergy. Then, based on the obtained results, elimination and provocation food test was performed in two phases - elimination phase and provocation phase. Diagnostic in vitro is needed to choose the level of medical establishment for conduction of oral provocation tests: in case a specific IgE index is over 0.7 kU/L, testing is performed in an intensive care unit, if IgE is less than 0.7 kU/L - in a specialized inpatient department. Three clinical cases involving different methods have been presented for diagnosing cow's milk protein allergy - elimination and provocation test, oral provocation test and administration of individual diet based on the obtained results. A complex diagnostic approach, in particular, study of anamnesis, record of nutrition diary, elimination diet, enables to optimize diagnostics of food allergy, and diagnostic addition of a product - to assess tolerance clinically during extension of diet. An elaborated method of diagnosing cow's milk protein allergy in children younger than one year of age can be recommended for wide use in a clinical practice.
