MILWAUKEE, M.I. — March 23, 2006 — New research shows that hereditary predisposition to develop asthma (atopy) is a determining factor in new cases on adult-onset asthma and that avoiding allergens may help prevent adults from developing asthma.

“Are atopy and specific IgE to mites and molds important for adult asthma?” is available in the March 2006 issue of the Journal of Allergy and Clinical Immunology (JACI), and online. The JACI is the peer-reviewed journal of the American Academy of Allergy, Asthma and Immunology.

Maritta S. Jaakkola, MD, DSc, of the University of Birmingham and the Finnish Institute of Occupational Health and colleagues conducted their study in the Pirkanmaa District in southern Finland with 485 cases of adult-onset asthma and 665 controls.

Allergy sufferers sniff out remedies
By Kate Schuler, Special to USA TODAY
With the prospect of weeks of coughs, itchy noses and dark circles under their eyes, many Americans are no longer content to attack their allergies with just one or two drugs in their arsenal.
Leonard Bielory, director of the Asthma and Allergy Research Center at the University of Medicine and Dentistry of New Jersey, says cold and allergy symptoms are one of the top reasons people seek out alternative treatments.
A 2002 study by the National Center for Complementary and Alternative Medicine at the National Institutes of Health found that 36% of adults in the USA had used some kind of non-conventional therapy to treat a variety of maladies during a 12-month period. Most of those who sought alternative therapies used them in combination with prescription drugs or other conventional treatments.
Despite the growing popularity of such treatments, there is scant scientific research on their effectiveness and safety.
“When a patient asks me whether they should try alternative or herbal medication, I counsel that it generally won’t be harmful, but it’s not likely to be beneficial, either,” says Brian Smart, an allergist in Glen Ellyn, Ill. Smart recommends that patients talk to their doctors about any supplements or alternative medicine they are using. “And they should carefully watch for side effects,” he says.

Complementary and alternative medicine encompasses a variety of treatments, including herbal and food supplements (even eating locally produced honey to boost the immune system with small doses of pollen), chiropractic services, acupuncture and other non-Western practices such as traditional Chinese medicine.
But the scientific community in this country has been slow to keep up with the public’s imagination when it comes to studying alternative ways to treat allergies: There is little conclusive data on whether alternative therapies work.
Little standardization
Adding to consumers’ uncertainty about the safety and effectiveness of alternative therapies is the way the Food and Drug Administration regulates supplements — as food, rather than drugs — so there is little standardization within the industry.
Mark Blumenthal, executive director of the American Botanical Council, a research and education group on supplements, says sorting through the information “is a daunting task and can be very confusing.”
But Blumenthal says alternative medicines have shown some promise for treating allergies. He cited promising early studies — one conducted by a Swiss allergy clinic and another by a U.S. naturopathic physician — of the herb butterbur and freeze-dried nettle leaves, as well as some herbal blends.
Doctors, however, don’t always know which treatments have been proven effective in trials. Indeed, the NIH survey showed that only about a quarter of people who used complementary and alternative medicine said a doctor suggested it.
A widely publicized study that appeared in The New England Journal of Medicine in July concluded that echinacea — the biggest-selling herbal supplement in the USA — was no better than a placebo at preventing or treating colds. (Some advocates countered that the dosage in the study was too low.)
“Yet people are still going to use it,” Bielory says. “So we have to learn what they’re using and if it has a positive effect, and what adverse effects” there might be.
“We want physicians to appreciate what is science and what is anecdote,” he says. “And for that, more research is needed.”
NIH has taken steps to fill that void. In 1992 it opened a research office on alternative medicine with $2 million funded by Congress, an initiative that has grown into a research center that grants nearly $108 million to scientists each year.
A possible ‘botanical drug’
One of those researchers is Xiu-min Li at the Mount Sinai School of Medicine in New York. A doctor trained in both Western and traditional Chinese medicine, Li is studying the effect of a combination of three Chinese herbs — ling zhi, ku shen and gan cao — on patients with asthma, and she says that because so many asthma patients are affected by allergies, it is possible the formula could be used widely in treating common allergies.
With funding from NIH, she derived the three-herb combination from a more complex formula commonly prescribed in China. Clinical trials are expected to begin within the next few months.
“I think people are very excited,” she says, about the possibility of a “botanical drug” that will have FDA approval. “This is a population that really wants to try an alternative approach.”
Meanwhile, patients also can make minor changes in their daily lives to help control their allergies.
Smart suggests patients use nasal saline that can be bought in pharmacies or mixed at home. “It moisturizes nasal surfaces and it will wash out bacteria and pollen,” he said.
“Close the house up and put the air-conditioning on,” says Thomas Platts-Mills, president of the American Academy of Allergy, Asthma, & Immunology. “You can reduce the amount of pollen.”
Platts-Mills adds: “There’re lots of very sensible things people can do. It doesn’t require taking medicine all the time.”

UK researchers have discovered a gene that causes dry skin and leads to eczema and possibly asthma.

University of Dundee researchers have discovered a new gene that, when mutated, causes eczema and may be associated with asthma. An estimated 10% of the European population carries this mutation, sometimes leading to severe, uncontrolled disease requiring specialist treatment. However, while the discovery holds promise for new treatments for these patients, these drugs are still a long way off.

The researchers have discovered a gene mutation that causes eczema and is associated with the development of asthma. The normal, working variant of this gene produces filaggrin, a protein usually found in large quantities in the outer layers of the skin and important in keeping the skin healthy.

The recently discovered gene may partially explain why this group of patients cannot be treated effectively, and could even lead to a new therapeutic approach to eczema and asthma targeting the core of the disease. However, while initial drug discovery programs are already being set up, a potentially curative new treatment will take many years to develop.
 

Eczemas seem to be interrelated with a lot of asthmatics. Anecdotal evidence suggests that once correct breathing volumes is achieved, eczema begins to decrease. For further information please contact us on info@buteyko.ie.

A new study shows asthmatic children living in multi-family housing units tend to have a harder time keeping their asthma symptoms under control. 

Researchers from the Yale Center for Perinatal, Pediatric and Environmental Epidemiology in New Haven, Conn., say this is due to the high prevalence of gas stoves in multi-family housing units. The stoves let off an excess amount of nitrogen dioxide, one of asthma’s worst triggers. 

According to study findings published in the February 2006 issue of the American Journal of Respiratory and Critical Care Medicine, children who are exposed to higher levels of indoor nitrogen dioxide are more likely to experience asthma-related problems like wheezing, persistent coughing, shortness of breath and chest tightness. 

This poses a serious problem for children with already sensitive airways, says Dianna Phares, a registered nurse practitioner and childhood asthma expert at Maryville University in St. Louis, Mo. “It’s a trigger, definitely,” she said. 

The Environmental Protection Agency (EPA) reports that nitrogen dioxide exposure in asthmatic people often creates increased bronchial reactivity. Nitrogen dioxide can also “make young children more susceptible to respiratory infections,” according to an EPA fact sheet on indoor environmental asthma triggers. 

More than half of U.S. households use gas-fueled heating and cooking devices, according to the Yale study. In the study, researchers found 45.9 percent of multi-family housing units surveyed had nitrogen dioxide concentrations at dangerous levels. That number fell to just 9.3 percent in single-family homes surveyed. 

Nitrogen dioxide becomes a common asthma trigger because “it irritates the eyes and nose and throat, and can cause shortness of breath in people with asthma,” Phares said. 

But there are steps parents can take to keep children and other family members with sensitive airways healthy, she added. “If you can avoid using the fireplace, that’s a priority. Use an exhaust fan over the stove, too, and try to get the ventilation out.” 

Other precautions include keeping chimneys cleaned and making sure not to run cars in the garage. 

Nitrogen dioxide is not the only trigger of asthma that parents should be aware of, Phares said. Hairspray, perfumes, cleaning products, aspirin, beta-blockers, exercise, cigarette smoke, pets and even the feces of cockroaches can also irritate the sensitive airways of an asthmatic. 

When an asthmatic encounters one of these triggers, “sensitive airways start to squeeze and swell, and that’s where the problem starts,” Phares said. 

To avoid asthmatic episodes, parents should watch for these triggers and try to pinpoint what precipitates a child’s asthmatic episode. Specific allergens can also be determined by a skin test done at the doctor’s office. 

Don’t expect your kids to grow out of their breathing difficulties, Phares said. While drugs and inhalers may keep the symptoms at bay, the sensitive airways that cause asthma will probably stay with a person for a lifetime. 

Keep track of how many times asthmatic children need to use an albuterol or corticosteroid “rescue inhaler.” Using the inhaler more than two times a day is too much, Phares said, and should signal another trip to the doctor to be re-evaluated for the necessity of maintenance medications. 

“No one should die from asthma,” Phares said. “It’s a very controllable disease.”

Overheated homes can cause a person to hyperventilate thus causing asthma. This is just one of the many topics covered in the Buteyko clinic to help control your asthma naturally.

Kids and adults with asthma can participate in just about any activity they want, with their doctors permission of course. Once asthma is under control there is really no limit to the things an asthmatic can do. The exception to this rule however, would be activities that include triggers to the persons asthmatic symptoms. For instance if dust and mold trigger your child’s asthma you would not want to let them make a day out of jumping in piles of leaves.
The one activity that many medical professionals feel is the most asthma friendly is swimming. Why swimming? Swimming is very low impact, it helps tone upper body muscles which can help breathing, the humid environment helps keep airways moist and it allows asthmatics to control the rate and depth of their breathing.
