Milk Protein Allergy In Infants

Suspected Delayed Allergic Reaction

If delayed cows milk allergy is suspected, skin prick testing and/or blood tests are not helpful. The diagnosis for delayed allergy needs to be confirmed or excluded by starting a trial elimination of all cows milk protein either from you babys diet in the case of a formula fed baby or from your own diet if you are exclusively breast feeding. Those babies who are formula fed need to be prescribed a special low allergy formula .

If it appears that your baby has reacted to cows milk protein coming through in your breast milk, you will need to eliminate all cows milk and all products containing cows milk from your own diet. This trial elimination diet will need to be guided by your GP or healthcare professional. If you are still exclusively breast feeding, your doctor may well wish to refer you to a dietitian to ensure that both your on-going nutritional needs and those of your baby are being met.

In the less common case where the suspected allergy symptoms are considered severe, your doctor will still need to advise starting this elimination diet. However if a clear improvement should be seen in the symptoms your doctor should not be advising any reintroduction of cows milk protein at home to confirm the diagnosis. The diet should be continued and the need for early referral to a childrens specialist allergy service for ongoing assessment and care should be discussed and made as soon as possible.

What Are The Symptoms Of Cows Milk Allergy

A wide range of symptoms can be triggered by a cows’ milk protein allergy, usually involving the skin, gastrointestinal tract, and respiratory tract. Those that involve the respiratory tract often appear along with other symptoms. These include:

IgE-mediated symptoms

• Skin reactions: Itchiness, reddening of the skin, sudden itchy rash , or swelling, most often of the lips, face, and around the eyes
• Gastrointestinal reactions: Swelling of the lips, tongue, or palate in the mouth, itchiness in the mouth, nausea, vomiting, colicky abdominal pain, or diarrhea
• Respiratory reactions: Itchy nose, sneezing, runny nose, congestion, cough, wheezing, or shortness of breath

Non-IgE-mediated symptoms

• Skin reactions: Itchiness, reddening of the skin, or eczema
• Gastrointestinal reactions: Acid reflux or gastro-esophageal reflux disease , loose or frequent stools , blood or mucus in poo, abdominal pain, colic, constipation, refusing food or aversion to food, redness in the perianal area, tiredness
• Respiratory reactions: Cough, wheezing, or shortness of breath

In rare cases, a child may have an anaphylactic reaction, which requires emergency medical help because it can be fatal. Call an ambulance if you think your infant is struggling to breathe or is floppy.

A cows’ milk protein allergy can sometimes lead to complications due to malabsorption or poor nutritional intake. The child may get chronic iron deficiency anemia or fail to thrive.

What Infant Formulas Are Not Suitable For Cma

There are many other infant formulas available that are not suitable for CMA:

• Partially hydrolysed formula the cows’ milk protein has been only partially broken down so can still cause an allergy. Examples include Karicare HA and Nan HA Gold Protect.
• Goats milk, sheep milk, mares milk these animal milks are not suitable for children or adults with CMA as the proteins are very similar to those in cows’ milk and most people will react to these too.
• Rice milk, oat milk, almond milk, cashew nut milk, coconut milk these plant-based milks are lower in energy, protein and fat. Some are fortified with calcium and B vitamins. Rice milk is not recommended for children under 5 years of age as the sole milk replacement because it does not meet their nutritional needs but can be used as a supplement with help and advice from a dietitian.

Is Breastfeeding Safe In Babies With Cma

You can continue to breastfeed infants with CMA. Breastfeeding alone is the best source of nutrition for all babies until the age of 6 months. For babies older than 6 months, you need to slowly introduce solids because breastfeeding alone is not enough for growth and development. If possible, babies should continue to be breastfed until they are at least 12 months of age. For babies that are breastfed only, mothers should continue breastfeeding. Many women can continue to have cows milk or dairy in their own diet without affecting the baby, but some women will also need to avoid but must avoid any foods or drinks that contain cows’ milk products or dairy. Your doctor or dietitian can help make this decision. Mothers who are avoiding dairy may need help to make sure they are getting enough calcium.

If this does not resolve symptoms, or if breastfeeding is not possible or adequate, or if you wish to wean your infant before they are aged 12 months, ask your doctor or dietitian for advice on which infant formula to try.

Can An Infant Outgrow Cows Milk Allergy

Most children will outgrow cowsâ milk allergy.

Studies show that most children with non-IgE-mediated reactions will outgrow cowsâ milk allergy by the time they are 3 years old.

For children with IgE-mediated reactions, studies show that about half of these children will outgrow cowsâ milk allergy by the time they are 5 years old. Evidence suggests that a cows’ milk protein allergy is more likely to persist in these children if they have asthma or allergic rhinitis, or if they have more severe reactions or higher milk-specific IgE antibody levels. Even so, itâs rare for adults to have a cowsâ milk allergy.

How Is A Milk Allergy In Babies Treated

If it turns out that your newborn is one of the 2 to 3 percent of babies who has a milk allergy, dont despair. Many children outgrow a milk allergy by the time they’re around 1 year old, and the majority of babies with milk allergies outgrow the condition by about age 3.

In the meantime, your child’s doctor may recommend the following:

• If your baby is formula-fed: Your pediatrician will suggest switching to a different formula. Because many babies with milk allergies are also allergic to soy , the doctor may suggest a hypoallergenic formula with hydrolysate protein, which has milk proteins that are already partly broken down, so its less likely to cause a reaction.
• If youre breastfeeding or exclusively pumping: Your pediatrician will likely recommend that you ditch dairy in your diet to see whether that makes a difference to your baby. Of course, making a major change to your diet is probably the last thing you want to think about when dealing with a fussy newborn, but it may very well resolve the issue. If you do eliminate dairy, be sure to talk with your doctor about how to make sure youre still getting enough calcium and other nutrients in your diet.

How Is Cma Treated

If your baby is diagnosed with CMA, you need to cut out cows’ milk, dairy products and any foods with cows’ milk-containing ingredients from their diet. Some infants and children with cows’ milk allergy can have dairy especially where it is a minor ingredient in a well-cooked food your doctor or dietitian can help decide if this is true for your child.If your baby is formula fed, you need to give them a non-dairy infant formula. There are 3 main types of non-dairy infant formula: soy-based formula, extensively hydrolysed formula and amino acid formula . The type of infant formula that is best for your baby depends on their age and the type of CMA they have. Ask your doctor or dietitian for advice on which infant formula to try.Read more about infant formula for cow milk allergy.

Alternative Tests For Food Allergy

The National Institute for Health and Care Excellence recommends that testing should not be sought from unreliable sources such as online or alternative practitioners. Such testing may include kinesiology, hair analysis, Vega testing and other blood tests. These should be avoided as there is no scientific evidence to support their use in diagnosing any food allergy and such testing may result in the unnecessary removal of important food groups from your babys or childs diet.

Cows Milk Allergy Usually Resolves

Around 80% of children will outgrow their cows milk allergy by the age of three to five years. Your doctor should advise if further allergy testing and food allergen challenges are needed. These are usually performed in hospital clinics and supervised by a clinical immunology/allergy specialist.

Cows’ Milk Allergy In Babies

Cows’ milk allergy , also called cows’ milk protein allergy, is one of the most common childhood food allergies. It is estimated to affect around 7% of babies under 1, though most children grow out of it.

CMA typically develops when cows’ milk is first introduced into your baby’s diet either in formula or when your baby starts eating solids.

More rarely, it can affect babies who are exclusively breastfed because of cows’ milk from the mother’s diet passing to the baby through breast milk.

There are 2 main types of CMA:

• immediate CMA where symptoms typically begin within minutes of having cows’ milk
• delayed CMA where symptoms typically begin several hours, or even days, after having cows’ milk

Gut Microbiota In Early Childhood

Human bodies are colonized by various microorganisms, the most influential of which is gut microbiota . The wide applications of next-generation sequencing technologies have potentiated the investigation of the structure and function of gut microbiota in a cost-effective way . The 16S rRNA gene sequencing technology is used to identify the composition of gut microbiota at the genus and phylum levels, while the shotgun metagenomic analysis and other strategies are used to explore the taxonomic and functional compositions of gut microbiota at species or strain level . The differences at the strain-level diversity of microbiota have shown distinct effects on the host phenotypes . Therefore, the understanding of interspecies diversity is important for the development of microbiome-based biomarkers linked to human health and disease . The integration of multi-omics technologies, including genomics, epigenomics, transcriptomics, proteomics, metabolomics, and microbiome, can help in the investigation, characterization, and quantification of microorganisms in human gut microbiota, giving insights into the interactions between host and its gut microbiota . Based on the functional properties and microbial associations, the potential microbial biomarkers can be identified and the personalized medicine protocols, including drugs, live probiotics, and microbial metabolites, can be designed for treatment purposes .

How Do Doctors Diagnose Milk Allergy

A doctor or allergist usually diagnoses milk allergies. They will ask about the childs medical history and do a skin prick test.

They will also ask a variety of questions about the babys symptoms. Before the appointment, it is helpful if caregivers keep a food diary of what the baby eats and the symptoms they experience.

Doctors may order a blood test to confirm the diagnosis. IgE antibodies in the blood indicate an immune reaction to an allergen.

A doctor may also recommend an oral food challenge . This involves eliminating milk from the babys diet before reintroducing a small amount in a medical setting. If there is a reaction, the doctor can treat it and confirm the diagnosis. Healthcare professionals conduct this in a medical setting due to the risk of anaphylaxis.

Diagnosis Of Cow’s Milk Allergy

Diagnosis of allergic reactions is usually obvious if symptoms occur soon after consuming cows milk or other dairy foods. This can be confirmed by your doctor after taking a medical history and using allergy tests.

Allergy tests that measure allergen specific antibodies called Immunoglobulin E to cows milk are usually positive for rapid onset reactions. There is no place in the diagnosis of cows milk allergy by non evidence based tests such as IgG, Vega, kinesiology, Alcat or allergy elimination tests.

Understanding Milk Protein Allergies In Infants

A milk protein allergy most often happens in babies who are fed cows milk formula. This occurs when the bodys immune system perceives cows milk protein as harmful and causes an allergic response.

According to a 2016 study published in the British Journal of General Practice, up to 7 percent of babies who are formula-fed are allergic to cows milk protein.

In some cases, though, it can occur in breastfed babies. According to the same 2016 study, up to 1 percent of babies who are breastfed develop an allergy to cows milk.

Certain genes have been identified in milk protein allergy. Up to 8 out of 10 children will outgrow the allergy by age 16 years, according to the American College of Allergy, Asthma, and Immunology.

Breastfeeding A Baby Who Can’t Tolerate Milk

If your baby is lactose-intolerant, you don’t need to change your diet. It doesn’t matter how much dairy you consume, the amount of lactose in your milk will be the same.

However, if your baby is diagnosed with milk allergy, you will need to remove all dairy from your own diet too. You will need calcium and vitamin D supplements every day. Your doctor or allergy specialist will advise you.
