Dr. Betschel explains the diagnostic process, which includes measuring C4 and C1 inhibitor levels and function, and emphasizes the role of clinical and family history in identifying potential cases. Genetic testing can also be useful in certain cases.

Clinical Manifestations and Triggers:

Learn about the varying clinical manifestations of HAE, which can differ significantly even among patients in the same family. Dr. Betschel highlights common triggers for HAE attacks, such as infections, trauma, and spontaneous episodes, emphasizing the importance of understanding these triggers for effective management.

Management and Treatment:

Discover the latest advancements in HAE treatment, including on-demand therapies for acute attacks and long-term prophylaxis options. Dr. Betschel discusses medications such as Icatibant, intravenous and subcutaneous C1 inhibitors, and the promising future of oral treatments and gene therapy.
