The Neglected Older Adults in Hereditary Angioedema: Insights From the ITACA Registry

Elderly patients with hereditary angioedema are undertreated with modern preventive therapy; this evidence drives urgent modernization efforts.

The ITACA Registry's 647-patient prospective analysis reveals elderly HAE-C1INH patients (≥65y) as a neglected subgroup with persistent disease activity and significant comorbidities, where guideline-recommended lanadelumab-based prophylaxis is underutilized and androgen-based treatments — contraindicated in older adults — remain prevalent. This provides evidence to accelerate prophylaxis modernization in an aging rare disease population.

HAE is a rare disease; elderly subgroup is doubly underserved; Italian multi-center registry data; treatment quality gap (androgen use in elderly) directly actionable.
