Is Eczema In Babies Caused By Food Allergies

Study Design And Setting

Food allergies and eczema in children

This was a follow-up study conducted 2 years after the completed RCT of a moisturizer skincare intervention for early infants, which was registered in the University Hospital Medical Information Network Clinical Trials Registry . The parents of these infants were recruited between March 2014 and February 2015 , at an obstetrics hospital in Tokyo. Skin barrier function, skin problems, and demographic data were collected during the participants first 3 months of life and details of that study are published elsewhere . The present study was conducted by mailing self-reported follow-up questionnaires to parents whose infants were aged 12 years old, between March 2015 and February 2017. The questionnaire asked about allergic diseases outcomes and focused on potentially related factors.

Food Allergy And Eczema Flare

  • Food allergies are a factor in 30% of young children with severe eczema. This factor is mainly seen in babies.
  • The main allergic foods are cow’s milk and eggs.
  • The main symptoms are increased skin redness and itching. Some parents report these symptoms start during or soon after the feeding.
  • The eczema becomes easier to control if you avoid the allergic food.

Only Try A ‘food Exclusion Diet’ If Your Child’s Eczema Does Not Improve With Treatment And Always With Medical Supervision

Before considering a ‘food exclusion diet’, follow the steps in ‘Managing eczema well’ above.

Confirming that food allergy is causing delayed eczema only needs short-term food exclusion. A health professional with allergy training should always supervise food exclusion diets. If the specialist recommends continuing food exclusion longer term, children should also see a paediatric dietitian with specialised knowledge of food allergies.

Is Milk Or Food Allergy A Problem And Should I Make Any Changes To My Babys Diet

Dietary allergy can occur in any child usually between three months and two years of age. Babies with eczema have a slightly higher risk of allergy, but lots of babies with eczema have no milk or other food allergy.

A baby with an immediate allergic reaction may have a sudden flare of eczema, become very itchy or start to wheeze, while a baby with a delayed reaction is more likely to have colic, reflux, vomiting and reluctance to feed.

If you think your baby has a food allergy, keep a diary, note any reactions, and ask for a referral to a paediatric dermatologist or allergist.

The vast majority of food allergy is limited to nine food groups: milk, egg, peanut, soya, wheat, tree nuts, sesame, shellfish and kiwi. Diagnosing food allergy in children up to the age of three is based on a history of symptoms. Treatment involves avoiding the food and then gradually reintroducing it. The only exceptions are peanut and shellfish as these are lifelong allergies.

Whatever happens, dont change your babys diet unless youve been advised to by a healthcare professional, as this may affect your babys growth and development.

Which Is The Best Emollient For My Baby

Signs of a Chocolate Allergy

Emollients treat dry skin by providing a surface film of oils. This increases water in the upper layer of the skin, restoring and providing a robust skin barrier, to prevent the entry of environmental agents or triggers.

Emollients soften the skin and reduce itch. If they are used regularly to maintain skin hydration, they can reduce the frequency of eczema flares. Leave-on emollients include lotions, creams,ointments and gels.

The emollient advised or prescribed for your baby should prevent dry skin and not cause irritation. You might need to try several products until you find the right one. Apply leave-on emollients regularly, throughout the day for example, at every nappy change and after bathing.

Use the product liberally . To apply the product, dot it all over the skin, and then smooth it in, using a gentle, downward, stroking motion rather than rubbing in.

Help Your Child Avoid Personal Irritants

Some substances can irritate skin and start the cycle of itching and scratching. If you notice that your child’s eczema gets worse after being exposed to something, help your child avoid it. Irritants are not the same for all children. If a common trigger does not bother your child, there is no reason to avoid it. Here are some examples of possible triggers that can cause eczema flare-ups in some children.

Perfumes and fragrances, including the skin care and bathing products that contain them

Harsh soaps

Bath salts or bubble baths

Rough clothing, including wool fabrics

Temperature extremes, including hot and cold, dry air

Skin Infections

Children with eczema often have more bacteria on their skin. Even when it does not cause an infection, the bacteria can make the skin more irritated and can make the eczema worse, so keeping clean is important.

Babies and children with eczema are also prone to skin infections. Infections make the eczema even worse and need to be treated by a doctor. An oral antibiotic, antibiotic cream or very small amount of bleach added to bath water might be prescribed. Bleach should not be added to bath water without guidance from your child’s doctor. Signs of possible infection include: increased pain, tenderness or swelling, hot skin, fever, pus, or red streaks extending from the affected skin.


Environmental allergens

Foods that are not allergens

My Child Has Eczema Should I Introduce Allergens

Research shows that babies with eczema are at a higher risk of developing food allergies. Fortunately, early and sustained exposure to allergenic foods is recommended for babies with eczema. In fact, new guidelines from the NIH are specifically focused on infants with eczema.

    FDA Acknowledges Qualified Health Claim Linking Early Peanut Introduction and Reduced Risk of Developing Peanut Allergy in 2017:

    For most infants with severe eczema and/or egg allergy who are already eating solid foods, introducing foods containing ground peanuts between 4 and 10 months of age and continuing consumption may reduce the risk of developing peanut allergy by 5 years of age. FDA has determined, however, that the evidence supporting this claim is limited to one study.

    How Eczema Cracks In The Skin Can Cause Food Allergies

    Many doctors are convinced cracks in eczema skin are the number one way that eczema causes food allergies and they have called it the Dual Exposure Hypothesis.

    Eczema causes itching and dry skin. Very dry skin, or skin that has been scratched enough, will develop cracks. Some of these cracks are too small to see, others bleed or have scabs. When babies get food all over themselves, or even just crawl around, bits of food or dust get into those cracks.

    A babys immune system will get scared by protein that it thinks broke through the skin. Once the immune system learns to be scared, it thinks harmless food is dangerous. This is what a food allergy is.

    How Eczema Infections Can Cause Food Allergies

    Preventing a lifetime of allergies by treating a baby’s skin

    Every persons skin is covered in bacteria, viruses, and fungi. One bacteria that is found on everyone is staph A. This bacteria is usually harmless, but when skin gets dry or cracked, like on babies with eczema, staph A jumps at the chance to spread out.

    Staph A is very dangerous if it gets into your blood, and your body knows that. If staph A infects dry skin, your babys immune system will go into attack mode, flooding the body with immune cells.

    In the LEAP study on peanut allergy prevention, doctors saw that almost all of the children with eczema who developed peanut allergy had a staph A infection. The kids with eczema but no infection had far fewer peanut allergies.

    When the immune system is on high alert, it does a bad job of telling friend from foe, and makes the mistake of a food allergy.

    What About Foods With A Label That Says May Contain Traces

    Many foods carry a warning on the label “may contain traces of “. This usually means that the food is made in a factory that also makes other foods that contain the listed food. Any possible trace would be so small that it is very unlikely to make the eczema worse. In general, foods labelled this way do not need to be avoided as part of an eczema diet. However if your child has had a severe allergic reaction to a food you should discuss what to do about these foods with your doctor.

    Can You Get An Allergy Test For Eczema

    In addition to those who suffer from moderate to severe eczema that isnt controlled by topical skin care, allergy testing may also be needed. For moderate to severe eczema, you might go to a dermatologist. Your dermatologist may explain allergy testing further when necessary and provide further assistance.

    Recommendations For Food Allergy Testing In Patients With Atopic Dermatitis

    While testing for food allergies is not warranted in all children with a new diagnosis of AD, it may be helpful in a specific subset of patients. The NIAID expert panel suggests that children less than five years of age with moderate-to-severe AD should be evaluated for a food allergy if they have intractable AD despite optimal management and topical treatment. Children should also be tested if they have experienced an immediate reaction following ingestion of a specific food.,

    If suspecting an immediate reaction, testing may include SPT and allergen-specific serum IgE tests. However, as stated earlier, these test for sensitization only. Therefore, neither test alone is diagnostic of food allergy, and positive test results must typically be confirmed via food challenge test.

    In cases of suspected late eczematous reactions, no accurate laboratory testing is available at this time, as the pathophysiology is unclear. Therefore, DBPCFCs remain the gold standard in diagnosis, with an observation period that extends to two full days. Some researchers have also recommended a diagnostic elimination diet, in which a suspected food is excluded for a period of 4 to 6 weeks. Since improvement in symptoms may be coincidental or due to placebo effect, confirmation by food challenge may still be required.

    What Is Eczema And How Common Is It

    Does my baby have acne or a rash? Diagnosis and treatment

    Eczema is a general term for a group of inflammatory skin conditions. Atopic dermatitis, the most common type of eczema, causes red, dry, and itchy skin. In infants, this form of eczema usually affects the face, scalp, and skin creases, but can also involve other areas of the body.

    Eczema affects up to 20% of children, and most cases begin in children before the age of five.

    Swelling Of The Face Lips And Eyes

    Your baby may take on a puffy look in their face, especially in the lips and around the eyes, if they are having an allergic reaction to a food. This is called angioedema.

    Treating the allergy with antihistamines should help the angioedema go away. Without treatment, the swelling will likely go away within a few days.

    This symptom is considered mild unless your baby also has swelling in the tongue and throat.

    Q : What Is The Scratch And Itch Cycle Of Eczema

    The scratch and itch cycle of eczema can cause discomfort, disrupt sleep and affect quality of life:

    • In people with eczema the skin does not retain moisture very well, which causes it to dry out easily.
    • This makes the skin more open to allergens and irritants, which can trigger the skin to release chemicals that make the skin itchy.
    • Scratching itchy skin causes more chemicals to be released, making the skin feel itchier.
    • If eczema is well managed this can avoid the scratch and itch cycle. It is therefore important to keep skin that is prone to eczema well moisturised, by using moisturising creams on the skin every day.

    How To Minimise Your Childs Allergies

    While eczema and allergies cannot be cured, they can still be treated and better managed. Here are other lifestyle tips by Dr David Ng on how to minimise the occurrence of allergies over time, especially for young children.

    • They should not be exposed to second hand smoking or smoke cigarettes as this may worsen asthma.
    • They should eat a healthy, balanced diet tailored for their specific growth milestones and needs.
    • They should exercise regularly and be mindful not to be overweight, as obesity can cause sleep problems which may compound conditions like allergic rhinitis.
    • Parents should not overly stress their children as this can worsen the symptoms of many allergic diseases such as the itch from eczema.
    • Finally, avoiding dirt at all costs may be counter-productive some studies have shown that the overly hygienic and sterile lifestyles that many people in cities live is associated with higher risk for allergic diseases like asthma, allergic rhinitis and eczema, compared to those who live in more dirty environments like farms. This is known as the hygiene hypothesis.

    Baby Food Allergy Rash

    Eczema and Food Allergies Often Go Hand and Hand

    Food allergy and food intolerance are often used interchangeably, but theyre very different. An allergy is an immune system response that causes a severe, often immediate reaction. Hives, lip swelling, vomiting, diarrhea, and wheezing may all be signs of an allergy. When a baby has an intolerance, hes missing the enzyme needed to break down a protein into digestible parts. This causes a milder reaction isolated in the digestive tract, like gas or cramps.

    Symptoms of allergies and intolerances can occur when babies begin solids but also during exclusive formula-feeding or breastfeeding.

    If your pediatrician suspects a food allergy, she may refer your child to an allergist who can perform skin prick tests and/or blood tests to confirm a diagnosis. Treatment usually focuses on avoiding trigger food, but its important that a doctor guides that plan. If you take food out of your childs diet that he isnt truly allergic to, this can actually make him more likely to have a reaction the next time he eats it.

    How The Study Findings May Help Babies Avoid Food Allergies

    The participant group of the study was small, but Leung says the team plans to study larger groups with the aim of making new treatment recommendations. The next step is to study infants from birth.

    When an infant is born, he or she goes from being in a wet environment to a dry one. This transition can damage the infants skin barrier, causing eczema. Leung plans to study infants from birth to try to figure out when these skin abnormalities develop. That way, doctors would be able to treat those who may be prone to eczema and food allergies early on.

    The skin samples from the study that showed abnormalities were from nonirritated skin. This is important because we believe the changes in the skin occur before you get a food allergy, Leung says. Theres a window of opportunity for you to treat skin and prevent food from invading through the skin.

    As for the ideal treatment to protect babies with eczema from developing food allergies, Leung says the team needs to do further research, but some existing emollients may be useful.

    It could be as simple as Vaseline around the lips to cause grease, which prevents food from going through the skin, or it may be applying certain lipids or fatty acids missing from their skin that could enhance skin development so its stronger, he says.

    Will My Baby Grow Out Of Eczema

    Sadly, it is impossible to predict whether your baby will have eczema for life or for just a short time. So far, there is no cure for eczema. Eczema is a chronic condition with periods of flare and periods of remission, and most people with a history of eczema still have problems with dry and itchy skin. If your child has a difference in their filaggrin gene, they will not grow out of it. Even if your baby appears to grow out of their eczema, it may return during the teenage years or in adulthood.

    Q : How Does Eczema Affect People Of Different Ages

    Eczema is a chronic health problem that affects people of all ages, but is most common in babies :

    • Infantile eczema occurs in around 20% of children under two years of age, and usually starts in the first six months of life. Infantile eczema usually improves significantly between the ages of two to five years.
    • Childhood eczema may follow infantile eczema, or start from two to four years of age. Rashes and dryness are usually found in the creases of the elbows, behind the knees, across the ankles and may also involve the face, ears and neck. This form of eczema usually improves with age.
    • Adult eczema is similar to that of older children with areas of very dry, itchy, reddened skin at the elbow creases, wrists, neck, ankles and behind the knees. It can cause rough, hard and thickened skin, which may also have weeping areas. Although eczema tends to improve in midlife, and is unusual in elderly people, it can occur at any age.
