Abstract
The article offers an overview of the progress in managing Hereditary Angioedema (HAE) in China, with a specific focus on the Greater Bay Area (GBA). Through the '4As' framework-Awareness, Access, Advocacy and Alliance-the article explores the challenges and advancements in HAE care. In terms of collaborative initiatives such as the HAE-ASIA (Angioedema Screening In Asia) collaboration and the GBA HAE Alliance "Hub-and-Spoke model" aim to bridge the gap between East and West, providing optimal patient care and advancing HAE management. By bridging the gap between East and West, the GBA aims to deliver optimal patient care and advance HAE management. Moving forward, it will be essential to persist in nurturing national and international collaborations, not only within China but also extending beyond its borders. These partnerships encourage the exchange of knowledge, research, and best practices, all of which are critical in propelling forward the care of HAE. By uniting as a worldwide community, we can significantly advance efforts to improve the quality of life for those affected by HAE across the globe.
