The leaky lung test: a pilot study using inhaled mannitol to measure airway barrier function in asthma.

: Airway epithelial barrier dysfunction is emerging as an important feature of asthma pathogenesis, but this is difficult to measure in individual subjects. We aimed to develop a noninvasive way to measure airway permeability in asthma. : Healthy controls and subjects with mild asthma inhaled dry powder mannitol in a dose-escalating manner on two separate occasions, stopping at 155 mg or 315 mg.
