Scientists one step closer to childhood asthma prevention

New study shines light on the link between eczema and asthma in childhood.
Infants with eczema are more likely to develop asthma later in childhood, new findings suggest.

According to a study carried out at the Washington University School of Medicine in the US, a substance called TSLP secreted by skin rash acts as a trigger for asthmatic symptoms in young children.

Author of the report, Dr Raphael Kopan, professor of developmental biology and of dermatology, said: "We've shown that skin can act as a signaling organ and drive allergic inflammation in the lung by releasing TSLP.

"Now it will be important to address how to prevent defective skin from producing TSLP. If that can be done, the link between eczema and asthma could be broken."

Commenting on the results, Dr Richard Anderson from the National Institutes of Health's National Institute of General Medical Sciences said that this could lead the way to future means of preventing or treating childhood asthma.

The NHS states that in the UK, more than 1.1 million children have asthma. Studies have shown that the condition is more common among boys than girls.
