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...

Journal Article
Pavord, I. D., Holliday, M., Reddel, H. K., Braithwaite, I., Ebmeier, S., Hancox, R. J., …Toelle, B. (2020). Predictive value of blood eosinophils and exhaled nitric oxide in adults with mild asthma: a prespecified subgroup analysis of an open-label, parallel-group, randomised controlled trial.

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

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
Hanratty, C. E., Matthews, J. G., Arron, J. R., Choy, D. F., Pavord, I. D., Bradding, P., …Heaney, L. G. (2018). 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...

The differential effects of azithromycin on the airway epithelium in vitro and in vivo (2016)
Journal Article
Slater, M., Torr, E., Harrison, T. W., Forrester, D. L., Knox, A., Shaw, D. E., & Sayers, I. (2016). The differential effects of azithromycin on the airway epithelium in vitro and in vivo. Physiological Reports, 4(18), 1-15. https://doi.org/10.14814/phy2.12960

Macrolides including azithromycin (AZM) can improve clinical symptoms in asthma regardless of infection status. The mechanisms underlying these benefi- cial effects are yet to be elucidated. The aim of this study was to determine the effect of AZM on... Read More about The differential effects of azithromycin on the airway epithelium in vitro and in vivo.

Azithromycin for Acute Exacerbations of Asthma: the AZALEA randomized clinical trial (2016)
Journal Article

IMPORTANCE Guidelines recommend against antibiotic use to treat asthma attacks. A study with telithromycin reported benefit, but adverse reactions limit its use. OBJECTIVE To determine whether azithromycin added to standard care for asthma attacks i... Read More about Azithromycin for Acute Exacerbations of Asthma: the AZALEA randomized clinical trial.

Analytical Methods, 8(27), 5407-5413. https://doi.org/10.1039/C6AY00938G

Current clinical tests employed to diagnose asthma are inaccurate and limited by their invasive nature. New metabolite profiling technologies offer an opportunity to improve asthma diagnosis using non-invasive sampling. A rapid analytical method for...
