Understanding how hepatitis delta progresses and responds to care

This is a research study that follows people who have hepatitis delta — a serious liver infection that happens when someone has both hepatitis B and hepatitis D viruses. Researchers want to collect information about how the disease develops over time and how well treatments work, so they can help future patients.

Hepatitis delta is rare, so doctors don't have enough experience treating it and managing it well. This study will gather real-world information to help doctors understand the disease better and provide better care for patients.
