New guidelines for managing cow's milk allergy in infants

Area of Science:

• Pediatrics
• Allergy and Immunology
• Gastroenterology

Background:

• Rising prevalence of allergic diseases, particularly food allergies in early childhood.
• Cow's milk protein allergy (CMPA) affects approximately 2% of infants in the UK, with up to 15% presenting suggestive symptoms.
• Current diagnostic and management approaches for CMPA in UK primary care are limited by lack of access to testing and facilities.

Purpose of the Study:

• To address the lack of consensus guidelines for diagnosing and managing CMPA in the UK.
• To discuss proposed international guidelines and their applicability to the UK context.
• To highlight the need for revisions and adaptations of international guidelines for the UK market.

Main Methods:

• Review of existing literature and proposed international guidelines for CMPA management.
• Analysis of diagnostic criteria including clinical history, allergy testing (SPT, IgE), and supervised milk challenges.
• Discussion of empirical treatment, hypoallergenic formulas, elimination diets, and diagnostic tests.

Main Results:

• No current consensus guidelines exist for CMPA diagnosis and management in the UK.
• International task force has proposed guidelines with algorithms for breast-fed and formula-fed infants.
• International guidelines cover diagnosis, management, hypoallergenic formulas, elimination diets, and diagnostic tests.

Conclusions:

• Revisions and adaptations of international CMPA guidelines are necessary for the UK market.
• Clearer guidelines are needed to support empirical treatment and specialist referrals.
• Improved diagnostic and management strategies are crucial for infants with suspected CMPA.
