The main goal of the Spanish IgG4-RD association (AE-IgG4) is to improve patient care and raise awareness of IgG4-RD. For this purpose, along with the medical board of committed national experts, it directly supports patients, provides educational resources, and facilitates connections with reference centres across Spain.

Voices From Our Board
Working together across borders is what makes real change possible for rare disease patients.
Being part of this network means our patients are no longer invisible. We finally have a collective voice that reaches the European institutions.
Starting a patient association can feel overwhelming, but the Federation gives the tools and the connections so you easily can succeed.
