Childhood Eczema May Lead to Adult Asthma
People who have eczema as a child are nine times more likely to develop allergic asthma as an adult. That is the result of a new study out of the University of Melbourne, the Murdoch Children’s Research Institute, and Monash University. The research is a follow-up to a study that began in 1968. The Tasmanian Longitudinal Health Study (TAHS) recruited all school children in Tasmania who were born in 1961 to participate in an asthma research study. Over 8,500 students participated in the study which included questionnaires about respiratory health and lung function testing.
In 2004, researchers followed up with the test subjects who were 44 years old at that time. The participants completed another survey about their respiratory health and had a skin prick test to check for allergies. Pamela Martin, a University of Melbourne PhD student who analyzed the results said, "In this study we see that childhood eczema, particularly when hay fever also occurs, is a very strong predictor of who will suffer from allergic asthma in adult life."
This trend from eczema to asthma is one example of a sequence doctors sometimes call the "atopic march" or "allergic march". When a patient develops an allergy, the body’s immune system is triggered to fight off the allergen that the body believes is attacking. This results in the creation of antibodies known as immunoglobulin E (IgE). Researchers believe that children who develop IgE early in life as a result of eczema and hay fever have a greater tendency to develop allergic asthma later in life.
Asthma is a chronic or long-term lung condition that makes it hard to breathe. During an asthma attack, muscles around the airways constrict and make the airways smaller which makes it harder for air to move in and out of the lungs. At the same time, the airways produce excess mucus which limits air movement. The result is wheezing and difficulty breathing.
Eczema or atopic eczema is a skin reaction that is similar to an allergy. It causes skin inflammation including blisters, itchy skin that may be scratched raw, redness, oozing, and bleeding. Eczema is most common in infants and may be outgrown later in life.

I suffer from eczema, and have since I was little. I also have a few pollen allergies, though they're not terrible. My doctors are sometimes bemused by the fact that I never developed adult-onset asthma. One of the things I do to help my skin and existing respiratory issues, though, is use a shower filter. I work for a company, Aquasana, that makes a really nice one, and it really has helped my skin condition. One of the things the shower filters remove is the chlorine that disinfects the public water supply (but is bad for our skin and hair and dries us out). People or kids with eczema should really try out a shower filter. I'm a believer!

Denise, WOW, this is amazing. I developed asthma at age 48. I had bad hayfever attacks as a child pre-teen, teen and young adult! Then I started taking vitamins and just had sinus attacks, now I have sinus, and asthma. I find that my asthma attacks are caused by environmental things, i.e. air quality, as well as chemicals i.e. smell of bleach etc, second-hand smoke, pollen and STRESS!
April 20, 2011 - 9:20amIf I cry, I set-off a sinus attack, this then will lead to ear problem, mucus, drainage, and then here comes an asthma attack! I am having big time the last couple of weeks. I HATE using the inhaler as it makes me so shaky, so I have been using eucalyptus medical grade essential oil (Wisdom of the Earth, is the bland) for last 10 years. This and rest brings me the relief that I need!
Thanks for this insightful article.

I really hope and pray that our son's childhood eczema has been stopped fast enough to avoid any asthma related conditions later on. He had severe eczema but once we gave him his Belly Boost children's probiotic, he amazingly got so much better. It was a miracle and answer to our prayers. Thanks for sharing this!
