Sponsored by Rush University Medical Center · Observational
Asthma is a very common childhood chronic illness and is generally more severe in African Americans. The investigators attempted to determine whether a specific immune marker is associated with lung function and asthma severity.
This study examined the relationship between Interleukin (IL)-13 from phytohemagglutinin-activated polymorphonuclear blood cells and asthma severity, lung function (measured as FEV1%), and total serum IgE levels in African American children with clinically diagnosed asthma
