Letter from Korea—Oral corticosteroid stewardship in Korea: Insights from the Korean Severe Asthma Registry (KoSAR).

The article discusses the prevalence of severe asthma in South Korea and the challenges associated with oral corticosteroid (OCS) use for managing severe asthma. The Korean Severe Asthma Registry (KoSAR) provides valuable insights into patients with severe asthma in Korea, highlighting the need for OCS stewardship to minimize risks associated with long-term OCS use. The implementation of OCS stewardship involves strategies such as biologics as alternatives to OCS, stepwise OCS tapering protocols, and multidisciplinary collaboration among healthcare providers. By adopting these approaches, the management of severe asthma in South Korea can be improved, leading to better patient outcomes and quality of life. [Extracted from the article]
