Summary

The aim is to assess the efficacy and specific safety in an observational study of patients with Chronic hepatitis D (CHD) with prospective follow-up, with antiviral treatment of 2 mg Bulevirtide (BLV) +/- PEG-IFNα-2a and +/- NA given as part of the patient's routine medical care. Also, explorative endpoints of biomarkers in peripheral blood, saliva, fecal sample and/or intrahepatic markers/signatures, and quality of life outcomes will be assessed.
