Black children with asthma appeared less likely than white children to have a fractional exhaled nitric oxide response to intramuscular triamcinolone, according to study results. Black children also experienced more exacerbations 4 weeks after administration of intramuscular triamcinolone.
Researchers from Royal Brompton & Harefield NHS Foundation Trust in London evaluated 79 children with severe therapy-resistant asthma for several factors, including assessment of steroid response.
Researchers classified a greater percentage of black children as FeNO nonresponders (86.7% vs. 45.3%; P < .05). Also, more black children experienced asthma exacerbations than white children (61% vs. 17%; P < .05).
