The Eczema, Allergies and Asthma March

1:45

Eczema refers to a number of different skin conditions in which the skin becomes red and irritated and sometimes has small, fluid filled bumps that ooze.

The most common cause of eczema is atopic dermatitis (sometimes called infantile eczema), which affects older kids as well as infants.

Children with eczema may eventually get food allergies, hay fever, or asthma. But you can take steps to soothe the itch and possibly cut the risk of allergies.

While most experts don't think eczema is purely allergic, it's clearly connected to allergic conditions like food allergies, hay fever, and asthma.

·      Up to 80% of kids with eczema get hay fever or asthma later in childhood.

·       35% of adults with asthma or nasal allergies had eczema as kids.

·      If a mom has allergies, there's almost a 1 in 3 chance that her baby will have eczema.

·      37% of kids with moderate to severe eczema also have food allergies.

For some kids, eczema and allergies develop in a specific order, as they get older. It starts with eczema, then food allergies, then asthma, and then hay fever. It's called the allergic march.

But just because your child has eczema doesn't mean they'll get these other conditions. It just means there's a higher risk.

There are several things that can increase a child’s risk of being part of the allergic march.  Kids who get eczema at a young age may be more likely to have allergies or asthma later. Kids with worse eczema symptoms may be more likely to get allergies or asthma.

You can do some things that might lower your child's chances of worsening eczema, asthma, or allergies. The evidence isn't clear, so talk to your doctor or your child's pediatrician. Depending on the situation, the doctor might recommend:

Breastfeeding your baby: It might lower the risk of eczema, later allergies, or asthma.

Diet changes: If your baby has a high risk of allergic problems, some doctors recommend changes in diet. Breastfeeding for at least 4 months can help protect your child. “Hydrolyzed” formula might help protect formula-fed babies.

Other ways to keep your child's eczema under control include:

Get allergy testing. If you can pin the problem on a specific allergen, you can figure out ways to avoid it.

Use a moisturizer. Go for thick creams and ointments that stop the skin from drying out.

Keep fingernails short. Your child will do less damage to the skin from scratching.

Avoid irritants. Always use unscented soap and laundry detergent. Stay away from cigarette smoke.

Watch for problems. If your child's eczema seems to be getting worse -- or if they get allergy symptoms, like congestion or a runny nose -- see a doctor. The sooner you get treatment, the sooner your child will feel better.

In many cases, eczema goes into remission and symptoms may disappear altogether for months or even years.

For many kids, it begins to improve by the age of 5 or 6; others may have flare-ups throughout adolescence and early adulthood.

In some kids, the condition may improve but then restart as they enter puberty, when hormones, stress, and irritating skin products or cosmetics are introduced. Some people will have some degree of dermatitis into adulthood, with areas of itching and a dry, scaly appearance.

Eczema is not contagious, so there's no need to keep a baby or child who has it away from siblings, other kids, or anyone else.

High-Sugar Intake During Mom’s Pregnancy May Double Child’s Risk of Asthma

2:00

It’s no secret that moms-to-be often develop a sweet tooth during pregnancy, but new information suggests high-sugar foods and drinks may double their child’s risk for developing asthma and allergies later in life.

Researchers from Queen Mary University of London used data gathered from nearly 9,000 mother-child pairs in the Avon Longitudinal Study of Parents and Children, an ongoing research project that tracks the health of families with children born between April 1, 1991, and December 31, 1992.

During the study, the participating pregnant women were asked about their weekly intake of certain foods and specific food items including sugar, coffee and tea. Their responses were used to calculate their intake of added sugar.

The researchers only saw weak evidence to suggest a link between women’s added sugar intake and their children’s chances of developing asthma overall. But when they looked specifically at allergic asthma—in which an asthma diagnosis is accompanied by a positive skin test for allergens—the link was much stronger. Children whose moms were in the top fifth for added sugar during pregnancy were twice as likely to have allergic asthma when compared to children whose moms were in the bottom fifth.

Children of mothers with the high-sugar diets were 38% more likely to test positive for an allergen and 73% more likely to test positive for more than one allergen, compared to those kids whose moms stayed away from added sugar.

"The dramatic 'epidemic' of asthma and allergies in the West in the last 50 years is still largely unexplained -- one potential culprit is a change in diet," said Annabelle Bedard, lead author and a postdoctoral fellow at Queen Mary's Centre for Primary Care and Public Health Blizard Institute. "Intake of free sugar and high fructose corn syrup has increased substantially over this period."

As with most studies, a cause and effect was not established, only an association. The study’s authors believe that the association is strong enough to warrant further investigation.

Lead researcher Professor Seif Shaheen  said: "We cannot say on the basis of these observations that a high intake of sugar by mothers in pregnancy is definitely causing allergy and allergic asthma in their offspring.

"However, given the extremely high consumption of sugar in the West, we will certainly be investigating this hypothesis further with some urgency.”

There are many health reasons why pregnant women should limit their intake of high-calorie and sugary foods and drinks. This research suggests that it may be prudent for the health of their unborn child as well.

Spring Allergies

1:30 to read

It is definitely allergy season around the country. The weird weather this year has made all things blooming start early, with sky high pollen counts. Some areas have had a few recent super cold days, but warmer temperatures are starting again.  While the cherry blossoms really suffered, the oak, elm, mulberry and ash trees are all just starting to spread their pollens and causing a lot of runny noses, itchy eyes and scratchy throats.

 

If you know that your child is a spring allergy sufferer or if they seem to be developing allergy symptoms (which often occurs after the age of 2 years), there are many products now available over the counter.  The mainstay of allergy treatment is the use of nasal steroids, which actually act as a preventative. They are used on a daily basis during allergy season.  There are many different nasal steroid sprays available including Flonase, Nasacort, Nasonex and Rhinocort.  Both Flonase and Nasacort now have a children’s brand and may be used in children as young as 2 years. While the word “steroid” scares many parents, these steroids are not “the bad”  ones associated with bodybuilding. The steroid is sprayed directly into the nasal lining and therefore very little is absorbed systemically, so there are few side effects. Some children do not like sprays and “water up their nose”, but each brand is a bit different in how it is delivered, so you might switch around and see which brand is easiest to use.

 

Many of the allergy symptoms that occur including the runny nose and watery eyes are related to the allergic cascade and histamines that the body produces in response to exposure to the pollen.  So….anti-histamines are also a mainstay of treatment. Again, many of the previous prescription anti-histamines are now all available over the counter. This class of drugs includes second generation non sedating anti-histamines such as Allegra, Zyrtec and Claritin and now the newest Xyzal.  First generation anti-histamines are more likely to cause drowsiness and sedation and the best known of these is Benadryl (diphenhydramine).  For those with severe allergy symptoms I sometimes use a morning non-sedating anti-histamine followed by Benadryl at bedtime. 

 

For those children who have significant allergies, particularly year round, and who do to respond well to typical treatment with nose sprays and antihistamines, it may be time to see a pediatric allergist. I recently sent one young boy for allergy testing. The testing is usually well tolerated and not painful.  When I saw him for follow up he told me he had gone to the “pokemon” doctor…as he had gotten lots of pokes on his back!!

Special Baby Formulas Don’t Prevent Asthma, Allergies

2:00

Parents that have a baby at risk or allergies, asthma or type-1 Diabetes sometimes turn to hydrolyzed milk formulas in hopes of lowering their infant’s risk of developing these problems.

A new review of the data on hydrolyzed formulas finds that there is no evidence that they actually protect children from these types of autoimmune disorders.

"We found no consistent evidence to support a protective role for partially or extensively hydrolyzed formula," concluded a team led by Robert Boyle of Imperial College London in England.

"Our findings conflict with current international guidelines, in which hydrolyzed formula is widely recommended for young formula-fed infants with a family history of allergic disease," the study authors added.

In the study, Boyle's team looked at data from 37 studies that together included more than 19,000 participants and were conducted between 1946 and 2015.

The investigators found that infants who received hydrolyzed cow's milk formula did not have a lower risk of asthma, allergies (such as eczema, hay fever, food allergies) or type 1 diabetes compared to those who received human breast milk or a standard cow's milk formula.

The researchers also found no evidence to support an FDA-approved claim that a partially hydrolyzed formula could reduce the risk of the skin disorder eczema, or another conclusion that hydrolyzed formula could prevent an allergy to cow's milk.

Other experts in the United States said that the finding casts doubt on the usefulness of these kinds of specialized products.

"Allergies and autoimmune diseases [such as asthma, and type 1 diabetes] are on the rise and it would be nice if we did have a clear route to preventing them," said Dr. Ron Marino, associate chair of pediatrics at Winthrop-University Hospital in Mineola, N.Y.

"Unfortunately, despite U.S. Food and Drug Administration support [for hydrolyzed formula], the data are not compelling," he said.

Dr. Punita Ponda is assistant chief of allergy and immunology at Northwell Health in Great Neck, N.Y. She stressed that when it comes to infant feeding, breast milk is by far the healthiest option.

However, "current mainstream guidelines for infant formula do recommend that parents consider using hypoallergenic formula if a close family member -- like an older brother or sister -- has a food allergy," she said. That was based on prior studies supporting some kind of protective effect, Ponda said.

Protein hydrolysate formulas were first introduced in the 1940s for babies who could not tolerate the milk protein in cow’s milk.

Protein hydrolyzed formulas are formulas composed of proteins that are partially broken down or “hydrolyzed.” They are also called hydrolysates.

There are two broad categories of protein hydrolysates:

•       Partially hydrolyzed formulas (pHF)

•       Extensively hydrolyzed formulas (eHF)

Both partially and extensively hydrolyzed protein formulas are based on casein or whey, which are proteins found in milk.  

Hydrolyzed formulas have had the protein chains broken down into shorter and more easy-to -digest chains. The more extensively hydrolyzed the formula, the fewer potentially allergenic compounds remain.

Hydrolyzed formulas are also more expensive than regular cow’s milk formulas and often harder to find.

The researchers review was published March 08, 2016 in the BMJ.

Allergy Nasal Sprays

1:30 to read

Since we are in the throes of allergy season (even though there was a recent late snow event in the midwest and northeast) I thought I would provide some additional information on steroid nasal sprays.  In fact, the climate changes that we are seeing are predicted to increase the length of pollinating seasons and therefore increase the amount of pollen produced, which will only make those with allergies (and children with developing allergies) even more miserable with symptoms of runny nose, sneezing, throat clearing and itchy eyes.  

Although I recently discussed the use of non sedating and sedating anti-histamines for intermittent allergy symptoms, the use of intranasal steroids have been found to be far more effective in controlling allergy symptoms.  The first thing to remember is that unlike an antihistamine, intranasal steroids require several days of consistent use before you will see any real change in allergy symptoms (I must repeat that line 10 times a day, especially to my teenage patients who want instant gratification!).  For anyone who knows the season for their allergies (depending on the pollen one is sensitive to), I recommend starting the intranasal steroid spray 1-2 weeks before their symptoms typically begin. (Which means if you are allergic to tree pollens - you should have already started by now). Using the nasal spray daily and continuing throughout the allergy season will provide the best results.  Watching the pollen counts in your area will be important to time the use of intranasal steroids.

Although some children seem to be more sensitive about using a intranasal steroid spray, it is well tolerated by most with few side effects.  Prescription intranasal steroid sprays have been approved for use in children as young as 2 years and the over the counter sprays for children 4 years and older.  The most commonly reported side effects are nasal irritation, burning and bloody noses.  I always try to show my patients how to use the spray properly and to “aim” the spray towards the outer aspect of the inside of the nostril rather than towards the septum (middle) which may help reduce irritation and bloody noses. By spraying towards the outer aspect you also maximize the amount of area that is covered by the spray.  Everyone seems to have their “favorite” intranasal steroid as some are an aqueous spray and others are an aerosolized puff….but in many cases the product choice may be based on the age of the patient, prescription vs OTC, insurance coverage and cost.  Although there are many to choose from there have been no head to head studies with these medications and their efficacy is generally thought to be comparable….but discuss your choices with your own pediatrician.

Lastly, there was a study done in 2014 published in The Journal of Allergy and Clinical Immunology, which measured growth rates in children between 5 and 8 years of age who were treated with an intranasal steroid (specifically fluticasone furcate - Veramyst ) as compared to a placebo. The study did show a significant improvement in nasal allergy symptom scores, but there was a 0.27 cm (0.65 inch ) reduction in growth rate over the course of the year as compared to placebo.  Due to this study, I use the lowest effective dose for the shortest amount of time in younger patients, and explain the reasoning to their parents.  Again, you can read the study and discuss this with your pediatrician before beginning intranasal steroids.   

Just make sure you use the intranasal spray consistently during the height of allergy season…I tell my own family, it doesn’t work as well if it sits on the counter for a few days between use!

Treating Allergies

In our special series, we look at ways to treat your allergiesAchoo!  Yes, it has been a particularly bad allergy season and (I'm afraid to say) it seems like it's going to be like this for a bit longer. I continue to see a lot of children (as well as their parents) complaining of nasal congestion, sneezing, itchy and watery eyes.  It's very uncomfortable!

The surge in allergies this year has been due to a very wet winter and the weather this spring has brought erratic temperatures and lots of wind.  This is the perfect storm for the "allergic cascade" to inflict itself on everyone's nasal mucosa. The best preventative for nasal allergy symptoms (allergic rhinitis) has been the use of intranasal steroids. These steroid sprays have been used for the past 15 years and clinical studies have shown that intranasal steroids are superior to oral antihistamines for preventing and treating allergic rhinitis. Intranasal steroids function by inhibiting the production of chemical mediators such as histamine and prostaglandin that cause inflammation and mucous production. In other words they are more of a preventative medication, while an antihistamine is treating the histamine that was released once you inhaled the offending tree or grass pollen. Intranasal steroids may also help eye allergy symptoms. The biggest problem seems to be getting young kids to let you use a nose spray on them. The same holds true for the older tween and teen crowd who complain that they "just don't have the time to use it every day" (it must take all of 15 seconds to use on yourself!) Intranasal steroids have been shown to be effective within 3-12 hours, although will reach their maximum effectiveness after several days to weeks of use, so using it daily and throughout the allergy season is going to give you the maximum therapeutic effect. There are many different brands available (all by prescription) and everyone seems to have their favorite. If one spray seems to bother your child due to scent, or intensity of the spray ask your doctor to try another brand. Many times they will have a sample and give you several to try and then prescribe the one that is easiest to get your child to use. It may be trial and error, but finding the right nasal steroid may just change your allergy season. By the way, God Bless You! Keeping allergens away from your family will help everyone feel better.  We’ll talk about this in part 3. Send your question to Dr. Sue!

Having a Baby? Keep Your Pets!

1:00

In a world full of allergens, you might think that having pets around could only make things worse.  But according to a new study from Canada, families with dogs and cats may unwittingly be protecting their infant children from not only allergies but obesity as well.

University of Alberta epidemiologist Anita Kozyrskyj and a team of researchers analyzed more than 700 Canadian children. They found babies exposed to pets while in the womb or up to three months recorded an "abundance" of ruminococcus and oscillospira (both are bacteria found in the gut,) the latter of which is associated with leanness or lower body mass index, notes the study - published in the journal Microbiome.

Kozyrskyj said the two types of bacteria increased "twofold" when a pet was in the house. The team said the theory is that early exposure to bacteria — like that from a dog — creates a type of resistance.

Unborn babies can benefit from allergy resistance by being indirectly exposed through their mother’s womb. The microbes can pass from pet to mother to baby.

Even if a parent decides not to keep pets after the baby is born, if pets were in the house during the pregnancy, the infant may gain some benefit anyway.

The findings also suggest pet exposure could cut down the risk of group B strep, which the Centers for Disease Control and Prevention said could cause blood infection, pneumonia and meningitis in newborns. Doctors treat against group B strep by giving mothers antibiotics during the delivery process.

Dogs were shown to offer higher levels of the beneficial microbes.

Pink Eye

1:30 to read

This is another time of the year that I see a lot “pink eye”.  Any time the eye is pink..you have “pink eye”, which mothers seem to be quite confused by!!   They often comment…”this is pink eye?” , to which I respond, “well, the child’s eye (conjunctiva) is pink (red), so yes…this is pink eye”.  The term is just a description of the eye….but then you need to determine why the eye is “pink”.

 

Conjunctivitis is one of the most common causes of a pink eye….and there are many different types of conjunctivitis.  As with any condition the history is really important in helping to determine why a child’s eye is inflamed.  Several of the most common causes of the “pink eye” are bacterial, viral and allergic conjunctivitis.

 

Bacterial conjunctivitis often shows up in younger children and they have lots of matting of the eye lids and lashes and a mucopurulent discharge (gooey eyes). Some moms say that the “goo of gunk” comes as quickly as they can wipe it.  The child often has a lot of tearing and will rub the eyes as they feel that something is in their eye and it is irritated.  Bacterial conjunctivitis will typically resolve in 8 -10 days on its own, but antibiotic eye drops are used to shorten the course  of the pink eye and also reduce the contagiousness.  It seems as if every child in a day care class room will get conjunctivitis as they constantly rub their eyes and touch toys!!  Hand washing helps….but you can’t wash a child’s hands every time they touch their eyes.

 

Viral conjunctivitis usually occurs in combination of with systemic viral illness. Sore throat, fever and bright red eye are often seen in older children and teens and is due to adenovirus.  While the eye is red, the discharge is typically watery and matting is much less common. These patients are contagious for up to 12 days so it is important to practice good eye/hand hygiene, especially in the household. Artificial tears may help the feeling of eye irritation, but antibacterial eye drops rarely help except in cases of a secondary infection.  I get many phone calls from parents saying, “we tried prescription eye drops and they are not working”. I make sure to tell my older patients to take out their contacts and wear glasses for 7-10 days.

 

At this time of year I am also seeing a lot of seasonal allergic conjunctivitis.  These children have intensely itchy and watery eyes, as well as swelling of the eyelids and area surrounding the eyes. They look like they have been crying for days as they are so swollen and miserable. Many also have a very watery nasal discharge. They do not have fever. Using over the counter medications for allergy control, such as nasal steroids and anti-histamines will help some of the allergic symptoms. There are also over the counter eye drops (Zaditor, Patanol) that help when used daily.  During the worst of the season I make sure that the child has daily hair wash and eyelash and eyebrow wash with dilute soapy water to make sure the pollen is removed after they have been playing outside. It is nearly impossible to keep a child indoors for the 6 or more weeks of allergy season!

“Furry Pets” May Help Kids Avoid Some Allergies

2:00

You might think that having pets would be a nightmare if you have small children with a family history of allergies. A new study says that furry pets may actually help protect children against some allergies.

The infants’ mothers had a history of allergy, so the babies were at increased risk too, and it was once thought that pets might be a trigger for allergies in such children, the authors point out in the Journal of Allergy and Clinical Immunology.

“Earlier it was thought that exposure to pets early in childhood was a risk factor for developing allergic disease,” said Dr. Merja Nermes of the University of Turku in Finland, who coauthored the research letter. “Later epidemiologic studies have given contradictory results and even suggested that early exposure to pets may be protective against allergies, though the mechanisms of this protective effect have remained elusive.”

Adding pet microbes to the infant intestinal biome may strengthen the immune system, she told Reuters Health by email.

The study team collected fecal samples from diapers when the babies were one month of age and these were tested for the DNA of two types of Bifidobacteria that are found specifically in animal guts: B. thermophilum and B. pseudolongum.

One third of infants from the pet-exposed group had animal-specific bifidobacteria in their fecal samples, compared to 14 percent of the comparison group. It’s not clear where the infants without furry pets at home acquired their gut bacteria, the authors write.

When the babies were six months old they had skin prick tests to assess allergies to cow’s milk, egg white, flours, cod, soybeans, birch, grasses, cat, dog, potato, banana and other allergens.

At six months of age, 19 infants had reactions to at least one of the allergens tested. None of these infants had B. thermophilum bacteria in their fecal samples.

Other studies have pointed out the connection between kids exposed to farm animals and household pets and building a better immune system.

“When infants and furry pets live in a close contact in the same household, transfer of microbiota between pets and infants occurs,” Nermes said. “For example, when a dog licks the infant´s face or hand, the pet-derived microbiota can end up via the mouth into the infant´s intestine.”

Human-specific Bifidobacteria have beneficial health effects, and animal-specific strains may also be beneficial, she said. It is still unclear, however, if exposure to these bacteria protects against allergies later in life, she said.

“Future research is needed to assess if these infants develop less atopic dermatitis, asthma or allergic rhinitis later,” she said.

Nermes also noted that she believes pediatricians should not discourage pregnant women or parents of infants from having pets in order to prevent allergies.

“If a family with a pregnant mother or an infant wants to have a pet, the family can be encouraged to have one, because the development of allergic disease cannot be prevented by avoiding pets,” she said.
