CLINICAL: CHILDREN’S HEALTH


50% of children with non-IgE-mediated CMPA have a concomitant soya allergy, which is in contrast to the significantly lower levels of soya allergy (7-14%) in IgE-mediated CMPA.17-20


In addition, higher


rates of adverse reactions to soya are reported in infants below 6 months of age in both IgE and non-IgE-mediated allergies.19 World Allergy Organisation17


The has therefore published guidelines


recommending that soya formulas should not be used below 6 months of age, and that EHF or AAF should be the preferred feed. The indications for using either EHF or AAF are highly debated.


Current guidance suggests the use of AAF in preference to an EHF in a child with a history of anaphylaxis/respiratory distress, severe atopic dermatitis, allergic eosinophilic disease, growth faltering and reactions to the traces of CM present in breast milk.11


THE CHALLENGES OF DIAGNOSING AND MANAGING CMPA A study by Sladkevicius et al. in 2010 highlighted that children with CMPA waited 3.6 months on average from the first visit to the general practitioner (GP) until the diagnosis of CMPA was confirmed.21


In


addition, there are limited allergy specialist centres in the UK to deal with the growing number of food allergy-related referrals.22


The


challenge therefore is not only to identify those children with CMPA, but to initiate treatment earlier at a primary care level.


THE ROLE OF PRIMARY CARE Due to the identified challenges related to the diagnosis and management of food allergy, NICE guidelines were published in 2011, guiding the diagnosis and assessment of food allergies in children in primary care.8

The aim of this document was to guide


healthcare professionals in primary care on the recognition of children with food allergies, but it does not discuss management. Soon after the publication of these NICE guidelines, the Royal College of Paediatrics published Care Pathways for children with food allergies in primary, secondary and tertiary care.23

These have


been developed around the competences required to diagnose and optimally manage food allergy, and have not been assigned to specific health professionals or settings in order to encourage flexibility in service delivery. With the help of these guidelines, it is hoped that children with


CMPA will be identified and managed in primary care, in addition to identifying those children that require a referral to secondary or tertiary specialist centre.


CONCLUSION CMPA is very prevalent in infants and young children and presents with a range of symptoms that may be IgE or non IgE-mediated. The allergy-focused clinical history is key to identifying a child with CMPA, and deciding which diagnostic pathway should be followed. Management of CMPA involves guidance on appropriate


avoidance of CM and may involve advice to breastfeeding mothers, and selecting the most appropriate hypoallergenic formula in non-breastfed infants. Dietary management can be very challenging and the dietitian (as per the NICE guidelines) plays a crucial role in this process.
