Description
Kang Li wrote a 2026 letter about how a breathing test result is read in bronchiectasis, a disease where airways stay widened and clogged with mucus. A recent study had linked a strong response to airway-opening drugs with worse lung function and more flare-ups. Li praises the work but raises points that could shift its meaning.
Chief among them: patients who respond may simply be those still using long-acting airway drugs on test day. Guidelines say those drugs should be stopped a day or two before testing, or the response looks smaller than it is. Li argues that how the test is run shapes the very definition being studied.
