Hepatitis Delta International Network (HDIN)
The Hepatitis Delta International Network is coordinated by the HepNet Study-House of the German Liver Foundation and brings together scientists, clinicians and health care associated individuals from all over the world to discuss and cooperate on all topics related to hepatitis delta.
The hepatitis D virus (HDV) causes the most severe form of viral hepatitis, requiring the presence of the hepatitis B virus (HBV) in order to propagate. It is estimated that approximately 12 million people worldwide are infected with HDV, making it a significant global health concern.
Initially, the network aimed to establish a large global database of patients with chronic HDV infection in order to better characterize the natural history of hepatitis delta and the response to antiviral therapy across different HDV and HBV genotypes, as well as diverse host genetic and environmental backgrounds. To this end, the Hepatitis Delta International Registry enrolled a total of 2,007 patients from 26 participating centers across 17 countries between 2011 and 2022.
As patient recruitment and data collection have now been completed, the network's primary focus has shifted to fostering scientific exchange and collaboration. Nevertheless, researchers interested in data analyses or collaborative projects related to hepatitis delta are warmly invited to contact us.
Meetings
The HDIN Meeting usually takes place twice a year: once in person at the EASL Congress, and once online. Members and guests of the Hepatitis Delta International Network meet to share recent data and present studies and findings on hepatitis delta, as well as discussing the latest topics. If you are interested in attending the meeting, please feel free to contact us.
The HDIN travel grant:
The HDIN travel grant is dedicated to young scientists and physicians (under 35 years old) to give them the opportunity to present their hepatitis delta research at one of the HDIN meetings.
The grant is sponsored by the German Liver Foundation (DLS) and the German Center for Infection Research (DZIF).
The grant covers travel, housing, and registration costs up to €1,500. For the travel grant application process and the travel grant reimbursement form, please contact our administrative coordinator.
