Towards Optimised Management of Cow’s Milk Protein Allergy

Cows' Milk Allergy

31/03/2021

This symposium took place during the 2018 meeting of the European Academy of Allergy and Clinical Immunology (EAACI). Focussing on the fundamental issues of suboptimal management of patients with cow’s milk protein allergy (CMPA), the speakers discussed key themes for optimising management.

Prof Madrazo-de la Garza evaluated the challenges of diagnosis and management of CMPA in infants. Nonspecific symptoms, indicative of other conditions, mean that CPMA is often misdiagnosed as lactose intolerance, a rare condition in infants. Increased awareness of CMPA symptoms and a clear distinction from lactose intolerance may facilitate earlier, accurate diagnosis and implementation of appropriate dietary interventions.

Dr Nutten followed by exploring variability in the composition of commercialised extensively hydrolysed formulas (eHF) intended for the management of CMPA and the associated potential clinical impact. Large variations in peptide profiles and residual allergenicity reflect a lack of definition for eHF composition. Although the clinical trials required to confirm the efficacy of eHF by demonstrating tolerance in >90% of infants with CMPA are performed, composition analyses for characterisation, quality control, and reproducibility are crucial for ensuring safe and suitable products throughout the product lifecycle.

Prof O’Mahony concluded the meeting by focussing on the importance of the gut microbiome in food allergy. The establishment of a stable gut microbial community closely tracks host growth and immune development. Delayed or altered establishment leads to microbiome immaturity, which has been associated with an increased risk of food allergies. Nutritional strategies, such as the use of eHF containing lactose, to support microbiome development complement existing CMPA treatment.¹

IMPORTANT NOTICE: Mothers should be encouraged to continue breastfeeding even when their infants have cows’ milk protein allergy. This usually requires qualified dietary counselling to completely exclude all sources of cows’ milk protein from the mothers’ diet. If a decision to use a special formula intended for infants is taken, it is important to give instructions on correct preparation methods, emphasising that unboiled water, unsterilised bottles or incorrect dilution can all lead to illness. Formula for special medical purposes intended for infants must be used under medical supervision.

The Benefits of Human Milk Oligosaccharides (HMO) on Immunity

Human milk contains bioactive components that confer protection on the newborn. These include complex carbohydrates called Human Milk Oligosaccharides (HMO). Research is revealing the full extent of the beneficial properties of HMOs.

Human Milk Oligosaccharides (HMO)

HMOs, the third solid component of human milk, are complex structures with a high potential for specific functions. HMOs and prebiotic oligosaccharides have completely different structures, which impact on their functions. Additionally to prebiotic effects, HMOs reduces adhesion of pathogens and have immune modulator effect.

Cows’ Milk Allergy Weaning Guide

The weaning guide contains recipes developed with leading dietitians from across the UK to help your patients' carers prepare milk-free recipes. The weaning guide can help give them confidence, that as their child grows, family meals can be adapted to make them suitable for CMA.

Evaluation of hypoallergenicity of a new, amino-acid based formula

Cows’ milk allergy (CMA) is one of the major food allergies during infancy and childhood. Hypoallergenic formulas can be necessary for managing infants and children with severe CMA. According to the American Academy of Pediatrics (AAP), a formula is “hypoallergenic” if it does not provoke allergenic activity in 90% of infants or children with confirmed CMA with 95% confid...

What do we know about lactose?

There is much confusion between the diagnostic terms ‘lactose intolerance’ and ‘cows’ milk allergy’, which are often used interchangeably, resulting in the potentially incorrect clinical management of these two distinct conditions.

A practical approach to managing a CMA infant with an extensively hydrolysed formula

A practical approach to managing a CMA infant with Althera™ Cows’ Milk Allergy (CMA) can occur in 1.8% - 7.5% of infants in the first year of life.1 The allergy is defined as an adverse reaction to the proteins in milk with most children growing out of their allergy by the time they reach one year. The treatment consists of the exclusion of cows’ milk from the infant’s diet. There...

Twins with cows’ milk allergy step down from AAF to EHF

16 weeks old, female twins were identified on EMIS search at a GP practise by an Oviva community dietitian for review. They were not already under the care of a dietitian and had both been started on Neocate LCP® for suspected cows’ milk allergy (CMA) at 6 weeks old by a paediatrician. The dietitian successfully switched both twins to SMA Alfamino and later stepped them down to SMA Althera.

Managing CMA with an Amino Acid Formula (AAF)

" MANAGING COWS’ MILK PROTEIN ALLERGY WITH ALFAMINO® Overview of cows’ milk protein allergy in infants Cows’ milk protein allergy (CMPA) is one of the most common food allergies in infants.1 Symptoms of CMPA include : Gastrointestinal (32-60% cases) Skin (5-90%) Anaphylaxis (0.8-9%) Respiratory Many of these symptoms overlap. CMPA can be classified into two groups: IgE mediated or non-IgE mediated (delayed hypersensitiv..."

The importance of having a choice of eHF and AAF milks in the management of CMA

During the last decade, the prevalence of allergic diseases in infants and children has increased significantly either through better awareness of the symptoms or through generally more children being affected.1-3 Therefore, it is no surprise that the numbers of children presenting to clinics in district general hospitals has also increased.4-5 Diagnosis of true milk allergy is key...

Human Milk Oligosaccharides: New Ways to Shape the Gut Microbiome in Cows’ Milk Protein Allergy

Prof O’Mahony began by discussing how the human gut is colonised by a wide diversity of microbes. He went on to review the evidence for how they exhibit highly evolved synergistic relationships to provide essential biological functions to the host and how the gut microbiome is influenced by many factors in early life. Prof Renz proceeded to describe the importance of establishing a s..

Safety and Efficacy of a new extensively hydrolyzed formula for infants with Cows’ Milk protein allergy

Cows’ milk protein allergy (CMPA) is the leading cause of allergy in infants. Previous studies assessing milk formulas with extensively hydrolyzed proteins have reported issues such as reactivity to residual allergens, bitter taste, and the impracticability of adding lactose.

Managing faltering growth with an Amino Acid Formula (AAF)
