Relief on the Horizon for Allergy Sufferers?

A new vaccine that reduces food allergies in dogs could
some day help people who suffer dangerous reactions to food like
peanuts, milk and wheat. The vaccine is also more evidence in
support of the so-called “hygiene hypothesis.” The Great Lakes

A new vaccine that reduces food allergies in dogs could some day help people who suffer
dangerous reactions to food like peanuts, milk and wheat. The vaccine is also more
evidence in support of the so-called “hygiene hypothesis.” The Great Lakes Radio
Consortium’s Tracy Samilton reports:


Allergies to foods like peanuts have become much more common over the past 20 years.
Some researchers believe it’s because, as a hygiene-conscious society, we’re no
longer exposing our bodies to infections that stimulate the immune system and protect
us from allergies. Pediatrician Dale Umetsu of Stanford University mixed a component
of Listeria bacterium and peanuts into a vaccine. He then gave it to dogs
with allergies so severe that one peanut made them sick.


“After the treatment, the dogs could tolerate up, on average, to 30 to 40 peanuts,
so this was quite an increase and the effect lasted several months, at least,
after the treatment.”


Umetsu says it could be five years or more before a vaccine is available for human trials.
A vaccine could help millions of people with food allergies.

Survey: Parents Missing Important Asthma Triggers

New research suggests that while parents of children who have asthma try to protect their youngsters from the things that trigger attacks, those measures often aren’t very helpful. The Great Lakes Radio Consortium’s Michael Leland reports:

New research suggests that while parents of children who have asthma
try to protect their youngsters from the things that trigger attacks,
those measures often aren’t very helpful. The Great Lakes Radio
Consortium’s Michael Leland reports:


Researchers at the University of Michigan found 80 percent of the
parents they surveyed were doing something to prevent attacks, but
often missed important measures. For example, a quarter of the parents
said a smoker lived in the same house as a child with asthma, but they
hadn’t done anything about it.


In one case, the parent of a child with pollen-triggered asthma bought
a new mattress cover, but didn’t close windows to keep pollen out of
the house.


Dr. Michael Cabana is a U of M pediatrician who led the study. He says
many parents also needlessly buy products they think will lessen asthma
symptoms.


“A lot of times, parents may get more information from other commercial
sources more often than the time they have to spend with either their
primary care doctor or their doctor who might be a sub-specialist in
asthma. So I think physicians have to do a better job putting that
information into perspective.”


Dr. Cabana suggests parents talk to their child’s doctor about asthma
triggers before spending money on asthma-related products.

Kids Using More Prescription Drugs

Environmentalists and health officials often worry about the widespread use of antibiotics in
cattle. But a recent report points to another concern: the rising use of such drugs in children.
Researchers found a jump in the number of children taking prescription drugs. The Great Lake
Radio Consortium’s Mark Urycki reports:


The survey was conducted by MEDCO, a pharmacy benefit management firm, and a division of
drug maker Merck. It found that prescription drug-use in children under 19 increased 85% over
the last five years. Although children still take fewer drugs than adults, MEDCO researchers say
it was the first time usage increased faster for kids than all other age groups.


The top drug use was antibiotics, with more than a third of the surveyed patients receiving such a
prescription each year. Health officials have expressed concern that the overuse of such drugs
could lead to drug-resistant bacteria.


A MEDCO researcher said the good news is that antibiotic use has at least flattened out. The
increased incidence of allergies, though, has not and the use of prescription allergy medicine
doubled from about 6% in 1997 to nearly 12% last year. Health officials suspect nearly twice as
many children today have allergies than 25 years ago.
