The Hepatitis Delta International Network (HDIN) registry was established in 2011 with participating physicians and scientists in Europe, Asia, North- and South America.
The aim of the HDIN registry is to characterize clinical and virological features of patients with HDV infection from all over the world.
The project is sponsored by the German Center for Infection Research (DZIF), the German Liver Foundation (Deutsche Leberstiftung) and the Hannover Medical School (MHH).
