Infants Wheeze Less In Homes With Multiple Dogs Living in a home with
multiple dogs may help reduce an infant's risk for developing wheezing in
the first year of life, according to new research from the University of
Cincinnati (UC).
Cincinnati researchers, led by David Bernstein, MD, have found that
infants living in homes with high levels of endotoxins (bacterial
contaminants) and multiple dogs were more than two times less likely to
wheeze than other infants.
They found that wheezing was not associated independently with either
dog or cat ownership or high levels of indoor endotoxins; however, high
endotoxin exposures in homes that also had multiple dogs resulted in
less wheezing.
Our research presents evidence that pet ownership offers a protective
effect against development of lower respiratory symptoms in young
children, adds Bernstein.
The UC-led team's findings conflict with earlier studies suggesting
exposure to high endotoxin levels or pet ownership can protect against
an increased risk for future allergic diseases, the UC team reports in
the December edition of theJournal of Allergy and Clinical Immunology.
Exposure to high endotoxin levels in the home may not be an important
determinant of aeroallergen sensitization during infancy, explains
Bernstein, professor of immunology and senior author for the study.
We do not yet understand how and why exposure to high levels of bacterial
endotoxin and multiple dogs in the home exert a protective effect in
these high-risk infants from wheezing early in life.
Endotoxins are natural compounds secreted from pathogens
(disease-causing agents) like bacteria that are commonly found in the
intestines and feces. Scientists believe that endotoxins can stimulate
our immune systems in many different ways.
Our bodies are programmed to produce allergic responses early in life,
Bernstein explains, but there are environmental factors like bacterial
endotoxins that may modify the immune system and block development of
allergies early in life.
The UC-led team analyzed the effects of pet ownership (cats and dogs)
and endotoxin exposure in 520 infants enrolled in the Cincinnati
Childhood Allergy and Air Pollution Study (CCAAPS) who were identified
as being at greater risk for developing allergies because at least one
parent had known allergies.
