In my role, running one of the largest severe asthma clinics in the UK, I’m all too familiar with the complicated relationship many people with severe asthma have with oral corticosteroids (OCS).
OCS are an effective treatment for acute asthma attacks and improve symptom control, however, they also have significant acute and long-term side effects.1-4 As a consequence, chronic and cumulative OCS exposure should be minimised whenever possible. Invariably, when my patients first come to see me their number one concern is their OCS use, and their number one question is – “How can I get off these medicines?”
The time has come to fundamentally change the role of OCS in severe asthma care.
Oral corticosteroids have been the mainstay of severe asthma treatment for over 60 years5
Severe asthma is a heterogenous and complex disease, with multiple underlying drivers.6,7 34 million people are affected worldwide,1,8 experiencing frequent exacerbations and significant limitations on their lung function and quality of life.1-4
For over 60 years we have relied on OCS as a mainstay of severe asthma treatment to help people manage their exacerbations.5 More than 13.5 million people worldwide with severe asthma currently rely on OCS to control exacerbations and prevent hospitalisations.1-3,9 This cumulative, long-term use of OCS is associated with debilitating side effects for patients and can place further burden on their quality of life.2,3,10 Chronic OCS use carries the potential for serious health risks, including diabetes, osteoporosis and heart disease.4,11,12 In fact, potential OCS-induced morbidities have been identified in 93 percent of people with severe asthma.11
OCS reduction in other disease areas gives us hope to replicate this success in severe asthma
In other disease areas we have seen a recent decline in the use of OCS, for example rheumatology, in which they were once the commonplace standard of care.5,13 For decades, steroids were used to help control symptoms for people with rheumatoid arthritis. 5,13 Now with earlier diagnosis, alongside the advent of novel treatments, rheumatologists have been able to revolutionise patient care and substantially reduce OCS use. 5,13
We must embrace learnings from other disease areas like rheumatology where clinicians have found success in reducing OCS use.5,13 When coupled with clear evidence on how to safely, effectively achieve this in severe asthma, we have the potential to dramatically change patient outcomes for the better.
Embracing evidence to inform guideline changes and adoption of OCS-sparing strategies
A growing body of evidence is emerging that could further inform guidelines to drive greater adoption of OCS-sparing strategies and enable physicians to safely and effectively taper their patients from OCS.14,15 This presents an important opportunity for those of us in the respiratory community to collaborate to ensure both physicians and patients understand the risks of OCS and why change is needed.
The medical community must embrace emerging evidence and put it into practice as quickly, but responsibly, as possible. As new, targeted therapies continue to emerge, alongside evidence supporting safe OCS-sparing strategies, I’m incredibly hopeful that we can achieve an improved approach to severe asthma treatment, which truly relegates OCS use to last resort.
