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...

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...

FourFold Asthma Study (FAST): a study protocol for a randomised controlled trial evaluating the clinical cost-effectiveness of temporarily quadrupling the dose of inhaled steroid to prevent asthma exacerbations. Trials, 17, https://doi.org/10.1186/s13063-016-1608-6

BACKGROUND: Asthma is one of the commonest chronic diseases in the UK. Acute exacerbations of asthma are unpredictable, disruptive and frightening. They cause considerable morbidity and account for a large component of the health service costs of ast...

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
Johnson, S. L., Szigeti, M., Cross, M., Brightling, C., Chaudhuri, R., Harrison, T. W., …Chauhan, A. (2016). Azithromycin for Acute Exacerbations of Asthma: the AZALEA randomized clinical trial. JAMA Internal Medicine, 176(11), https://doi.org/10.1001/jamainternmed.2016.5664

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.

Assessment of a rapid liquid-based cytology method for measuring sputum cell counts (2016)
Journal Article
Martin, M., Lee, H., Meakin, G., Green, A., Simms, R., Reynolds, C., …Harrison, T. W. (in press). Assessment of a rapid liquid-based cytology method for measuring sputum cell counts. Thorax, https://doi.org/10.1136/thoraxjnl-2016-208817

Differential sputum cell counting is not widely available despite proven clinical utility in the management of asthma. We compared eosinophil counts obtained using liquid-based cytology (LBC), a routine histopathological processing method, and the cu...

Multiple Circulating Cytokines Are Coelevated in Chronic Obstructive Pulmonary Disease (2016)
Journal Article
Selvarajah, S., Todd, I., Tighe, P. J., John, M., Bolton, C. E., Harrison, T. W., & Fairclough, L. C. (2016). Multiple Circulating Cytokines Are Coelevated in Chronic Obstructive Pulmonary Disease. Mediators of Inflammation, 2016, 1-9. https://doi.org/10.1155/2016/3604842

Inflammatory biomarkers, including cytokines, are associated with COPD, but the association of particular circulating cytokines with systemic pathology remains equivocal. To investigate this, we developed a protein microarray system to detect multipl... Read More about Multiple Circulating Cytokines Are Coelevated in Chronic Obstructive Pulmonary Disease.

Untargeted metabolic profiling of saliva by liquid chromatography-mass spectrometry for the identification of potential diagnostic biomarkers of asthma (2016)
Journal Article

Untargeted metabolic profiling of saliva by liquid chromatography-mass spectrometry for the identification of potential diagnostic biomarkers of asthma. 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...

The utility of exhaled nitric oxide in patients with suspected asthma (2016)
Journal Article

The value of FENO measurements in patients with symptoms suggestive of asthma is unclear. We performed an observational study to assess the ability of FENO to diagnose asthma and to predict response to inhaled corticosteroids (ICS). Our findings sugg...
