Introduction: Based on the latest literature evidence, between 30% and 60% of adults with severe refractory asthma (SRA) are systemic corticosteroid (SCS) dependent. There are numerous therapeutic options in asthma, which are often not effective in severe forms. In these cases, SCS should be considered, but it is increasingly recognized that their regular use is often associated with significant and potentially serious adverse events.
Areas covered: The aim of this article is to provide an update about the recent and significant literature on SCS and to establish their role in the management of SRA. We summarized the most important and recent evidence and we provided useful indications for clinicians.
Expert opinion: There is now strong evidence supporting the increased risk of comorbidities and complications with long-term SCS therapies, regardless of the dose. New evidence on SCS tapering and withdrawal will allow to define protocols to address SCS management with greater safety and effectiveness, after starting efficient steroid-sparing strategies. In the next 5years, it will be necessary to implement corrective actions to address these unmet needs, to reduce the inappropriate use of SCS by maximizing the application of more innovative and effective therapies.
