Scientists find predisposition to bronchiolitis in some babies
Date:10/19/2007

aediatrician based at Alder Hey, said: This work helps to explain a common observation about children who had bronchiolitis as babies. Parents often tell us that every time their child gets a cold it goes straight to his chest and many parents and doctors believe that bronchiolitis in infancy is the cause of these chest problems in childhood.

This study shows that it is the difference in the childs ability to fight viruses that predisposes them to bronchiolitis in the first place. That poor ability to fight the condition is an innate feature of their immune system. Bronchiolitis just happens to be the commonest respiratory virus around and therefore the first virus a baby is likely to come across.

Because the gamma interferon response is an important feature of the immune system in these children, they wont handle subsequent respiratory viruses very well either. The association between bronchiolitis in babies and chestiness in childhood is not causal or consequential but due to a common immune predisposition and is probably genetic.
