Rationale: The utility of fractional exhaled nitric oxide ( ) suppression (FeNOSuppT) to identify non-adherence to inhaled corticosteroid (ICS) treatment has previously been reported, but whether it can predict clinical outcome remains unclear.
Objectives: We examined the utility of FeNOSuppT in prediction of progression to biologic agents or discharge from specialist care.
Methods: FeNOSuppT was measured at home using remote monitoring technology of inhaler use alongside daily measurement over 7 days.
Background: Reduction in glucocorticoid exposure is the primary benefit of new biologic treatments in severe asthma, but there is currently no evidence that reduction in glucocorticoid exposure corresponds to a proportionate reduction in associated toxicity.
Objectives: To use the validated Glucocorticoid Toxicity Index (GTI) to assess change in glucocorticoid toxicity after 12 months treatment with mepolizumab, and compare toxicity change to glucocorticoid reduction and change in patient-reported outcome measures (PROMs).
Methods: A longitudinal, real-world prospective cohort of 101 consecutive patients with severe asthma commenced on mepolizumab in a specialist UK regional severe asthma clinic.

Background: Glucocorticoid (GC)-associated morbidity in severe asthma (SA) is well recognized but varies in individual patients; systematic measurement of GC toxicity is important to measure improvement with steroid-sparing monoclonal antibodies.
Objective: To describe for the first time individual patient GC toxicity in steroid-dependent SA using the Glucocorticoid Toxicity Index (GTI).
Methods: An observational consecutive patient cohort study was performed at a UK Regional SA Specialist clinic for systematic assessment of GC-associated morbidity using the GTI in routine clinical care.
