Washington DC: A new study has showed that vehicular pollution escalates asthma risk in children.
The findings states that residential distance to a major road (a marker of exposure to traffic-related air pollution TRAP) is associated with increased allergic inflammation.
The exposure is associated with increased plasma levels of interleukin 31 (IL-31), a cytokine that promotes allergic inflammation.
Franziska Rosser, co-authors of the study, has compared the blood levels of cytokines and signaling chemicals produced by the immune system that can stimulate inflammation - in children with and without asthma.
Children living in closer proximity to a major road had higher levels of some cytokines that regulate immune responses and inflammation known to have a role in asthma.
"Exposure to traffic-related air pollution has been associated with increased prevalence of new onset asthma in children and exacerbations in children with pre-existing asthma," she said.
The study was published in Pediatric Allergy and Immunology Journal.
