Journal Article
Heaney, L. G., Busby, J., Hanratty, C. E., Djukanovic, R., Woodcock, A., Walker, S. M., …Yang, F. (2021). Composite type-2 biomarker strategy versus a symptom–risk-based algorithm to adjust corticosteroid dose in patients with severe asthma: a multicentre, single-blind, parallel group, randomised controlled trial. Lancet Respiratory Medicine, 9(1), 57-68. https://doi.org/10.1016/s2213-2600%2820%2930397-0

Background
Asthma treatment guidelines recommend increasing corticosteroid dose to control symptoms and reduce exacerbations. This approach is potentially flawed because symptomatic asthma can occur without corticosteroid responsive type-2 (T2)-driv...

Background
Whether blood eosinophil counts and exhaled nitric oxide (FeNO) are associated with important outcomes in mild asthma is unclear. In this prespecified subgroup analysis of a previously published open-label clinical trial, we aimed to asse...

Controlled Trial of Budesonide–Formoterol as Needed for Mild Asthma (2019)
Journal Article
Beasley, R., Holliday, M., Reddel, H. K., Braithwaite, I., Ebmeier, S., Hancox, R. J., …Weatherall, M. (2019). Controlled Trial of Budesonide–Formoterol as Needed for Mild Asthma. New England Journal of Medicine, 380(21), 1-11. https://doi.org/10.1056/nejmoa1901963

BACKGROUND
In double-blind, placebo-controlled trials, budesonide–formoterol used on an as-needed basis resulted in a lower risk of severe exacerbation of asthma than as-needed use of a short-acting β2-agonist (SABA); the risk was similar to that of...

A randomised pragmatic trial of corticosteroid optimization in severe asthma using a composite biomarker algorithm to adjust corticosteroid dose versus standard care: study protocol for a randomised trial (2018)
Journal Article

A randomised pragmatic trial of corticosteroid optimization in severe asthma using a composite biomarker algorithm to adjust corticosteroid dose versus standard care: study protocol for a randomised trial. Trials, 19, Article 5. https://doi.org/10.1186/s13063-017-2384-7

Background: Patients with difficult-to-control asthma consume 50–60% of healthcare costs attributed to asthma and cost approximately five-times more than patients with mild stable disease. Recent evidence demonstrates that not all patients with asthm...

Peripheral killer cells do not differentiate between asthma patients with or without fixed airway obstruction (2016)
Journal Article
Tubby, C., Negm, O. H., Harrison, T. W., Tighe, P. J., Todd, I., & Fairclough, L. C. (2017). Peripheral killer cells do not differentiate between asthma patients with or without fixed airway obstruction. Journal of Asthma, 54(5), 456-466. https://doi.org/10.1080/02770903.2016.1236941

Objective: The three main types of killer cells – CD8+ T cells, NK cells and NKT cells – have been linked to asthma and chronic obstructive pulmonary disease (COPD). However, their role in a small subset of asthma patients displaying fixed airway obs...

MMP-1 activation contributes to airway smooth muscle growth and asthma severity (2016)
Journal Article
Naveed, S.-U.-N., Clements, D., Jackson, D. J., Philp, C., Billington, C. K., Soomro, I. N., Reynolds, C., Harrison, T. W., Johnston, S. L., Shaw, D. E., & Johnson, S. R. (2017).

American Journal of Respiratory and Critical Care Medicine, 195(8), 1000-1009. https://doi.org/10.1164/rccm.201604-0822OC

Introduction: Matrix metalloproteinase-1 and mast cells are present in the airways of people with asthma. We hypothesised that matrix metalloproteinase-1 could be activated by mast cells and increase asthma severity. Methods: Patients with stable ast...

The differential effects of azithromycin on the airway epithelium in vitro and in vivo (2016)
Journal Article
