Abstract

This thesis examines the overarching theme of inhaled corticosteroid (ICS) dose response effects on a variety of asthma outcome measures; with further importance placed on the application of these findings to personalising ICS dosing for the individual asthmatic.

The introduction provides a detailed summary of the current recommendations for the treatment of adult asthma, with particular reference to the mechanism of action and clinical utility of ICS for the treatment of asthma. Current methods of assessing ICS dose response are presented, as well as the common influences that affect these responses. Novel therapeutic theories and the identification of specific asthmatic phenotypes are also introduced, in order to demonstrate the shift towards personalising treatment for asthma.

The first two studies examine the dose response of ICS on two specific factors that influence asthma. The third study presents an examination of pharmacological manipulation of the ICS dose response using an additional agent. The following two studies address: how asthma outcomes relate to each other in patients receiving ICS; in addition to an overall assessment of the ICS dose response across a broad range of both ICS moieties and outcome measures. The final study examines for any detrimental effect of an ICS dose ramp on bone metabolism, an important potential long-term adverse effect of higher ICS dosing.

The discussion draws together all the results obtained in relation to ICS dose response in asthma, and how these apply to current clinical practice for the individual patient. Furthermore, hypotheses are generated for areas of future study based on the findings from this work.
