Combined traffic and indoor pollutants may trigger asthma

December 28, 2009
Environmental health scientists report that children exposed to high levels of both traffic-related and indoor pollutants are six times more likely to experience "persistent wheezing," an early indication of asthma.

The University of Cincinnati College of Medicine research team studied young children believed to be at high risk for allergies later in life and found that 36 percent of those exposed to both traffic pollution and indoor endotoxin were wheezing at age 3. Those exposed to low levels of the pollutants, or high levels of traffic pollution alone, were less likely to experience persistent wheezing.

The study findings were published in a December issue of the American Journal of Repiratory and Critical Care Medicine. It is believed to be the first study to look at the combined effects of traffic-related and indoor pollutants as an indication of later asthma development.

At North Shore University Hospital in Manhasset, New York, researchers are studying the drug tiotropium, a solution administered through an inhaler, to gauge its effectiveness in controlling asthma symptoms as it is used along with patients' usual asthma medications. The clinical trial is conducted through the Feinstein Institute for Medical Research, the research arm of the North Shore-LIJ Health System.ADNFCR-2730-ID-19531116-ADNFCR
