Brief summary
This is a multicentre observational study with prospective and retrospective data collection and retrospective data collection and biological collection from patients with HBV/HDV co-infection.
Detailed description
This is an observatory for patients co-infected with hepatitis B and Delta viruses. Patients will be monitored according to the usual recommendations, depending on their status: * Patients who have never received specific treatment for hepatitis Delta (untreated or receiving treatment with peginterferon alpha 2a alone) will be monitored according to current recommendations, once every 6 months; * Patients treated or having been treated with a specific hepatitis Delta treatment will be monitored according to the compassionate access protocol or according to the recommendations of the AMM during treatment and according to routine follow-up after the end of treatment. Participation in research entails the following additional procedures for patients, for each line of treatment, where applicable: * Samples for the biobank, * Self-administered questionnaires. In addition, as sub-studies are planned on sub-groups of patients, these sub-studies may involve additional constraints/interventions
Interventions
Blood sampling for the biobank and, in addition, as sub-studies are planned on sub-groups of patients, additional blood samples are planned for the patients in these sub-studies.

Inclusion criteria
* Age \> 18 years, * Presenting a chronic HDV infection (positive serology), * Who gave his written informed consent before any intervention and the day of inclusion at the latest, * Affiliated to Health Insurance or to the Aide Médicale d'Etat (request for exemption pending).
Exclusion criteria
* Patient participating in another biomedical research with an exclusion period ongoing at inclusion, * Vulnerable patient (minor, adults legally protected: under judicial protection, guardianship, or supervision, persons deprived of their liberty). * Patients with predictable difficulties of follow-up according to the investigator.
