Study Notes
Symptoms and Signs of Cow's Milk Allergy (CMA)
- Symptoms span multiple systems: skin (urticaria, angioedema, eczema), gastrointestinal (vomiting, abdominal pain, constipation), and respiratory (rhinorrhea, sneezing, dyspnea).
- Severe reactions can lead to systemic issues like cardiovascular collapse.
- Reactions primarily occur after milk ingestion, but can also result from inhalation or skin contact with milk.
Diagnosis of CMA
- Diagnosis begins with an allergy-focused clinical history and a thorough physical examination.
- Important to collect information about the infant’s feeding practices and any personal or family history of allergic diseases.
Elimination Diet Techniques
- Non-IgE mediated CMA requires a diagnostic elimination diet lasting 2–4 weeks before reintroduction of milk.
- IgE-mediated allergies may have a shorter elimination period of 1–2 weeks.
- Recovery is typically faster in IgE-mediated allergies compared to non-IgE mediated cases.
Improvement Timelines
- Improvement in infants with severe atopic dermatitis may take 6 to 8 weeks, aligning with natural disease progression.
Evidence for Formulas in CMA Management
- Cow's milk-based extensively hydrolyzed formulas (eHFs) are recommended for diagnostic elimination diets.
- Hydrolyzed rice formulas (HRFs) and soy formulas may also be beneficial, but lack sufficient evidence for recommendation.
Over-Diagnosis Concerns
- Over-diagnosis of CMA can occur in children who exhibit symptoms due to other conditions, leading to unnecessary elimination diets and potential harm.
