APACS (Associazione Pazienti con Sindrome di Churg Strauss) is an Italian organization founded in 2016 by a group of patients living with Churg Strauss Syndrome, also known as Eosinophilic Granulomatosis with Polyangiitis (EGPA). The association’s core mission is to provide comprehensive support to individuals affected by this rare disease. They achieve this by offering crucial information about the syndrome, providing initial assistance to newly diagnosed patients, and directing them to specialized reference centers or doctors.
