Better Classification of Respiratory Amyloidosis
- Conditions
- Amyloidosis
- Registration Number
- NCT05862961
- Lead Sponsor
- Assistance Publique - Hôpitaux de Paris
- Brief Summary
The B-AR project is based on a retrospective analysis of amyloidosis typing and the identification of their amylogenic protein.This work should be able to unite many clinicians, including pulmonologists and pathologists around a rare disease that still suffers from insufficient data.
- Detailed Description
The B-AR study will highlight the interest of proteomic analysis of amyloidosis compared to their identification by immunostaining. The objective is to reduce diagnostic wandering and to improve patient management. The typing of respiratory amyloidosis will allow a better characterization of the disease and thus, to propose a dedicated therapeutic management.
