National Cohort of Patients Co-infected with Hepatitis B and Delta Viruses

Recruiting
Conditions
Hepatitis B, Chronic
Hepatitis D, Chronic
Registration Number
NCT04166266
Lead Sponsor
ANRS, Emerging Infectious Diseases
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
