Assessing Hepatitis D prevalence in HIV and HBV coinfected patients in Europe

Euro-HDV:Epidemiology and Clinical Course in Patients With HIV and Hepatitis B/D -Coinfection

Observational University Hospital, Bonn · NCT06264583

This study is trying to find out how common Hepatitis D is in people who have both HIV and Hepatitis B in Europe, while also looking at how well current testing guidelines are being followed.

What this trial studies

This observational study aims to evaluate the prevalence of Hepatitis D virus (HDV) among individuals living with HIV and chronic Hepatitis B virus (HBV) infection across several European countries. It will assess the implementation of EACS guidelines for HDV testing and analyze existing data to determine the rates of HDV infection and associated risk factors. Additionally, a cohort and database will be established for future studies on HDV among this population, incorporating clinical, virological, and laboratory parameters.

Who should consider this trial

Good fit: Ideal candidates for this study are adults living with HIV who also have chronic HBV infection.

Not a fit: Patients who have cleared HBV infection or are under 18 years of age will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved screening and management of HDV in HIV/HBV coinfected patients, potentially reducing liver disease-related complications.

How similar studies have performed: Other studies have shown varying rates of HDV infection in similar populations, indicating that this approach is relevant and necessary for understanding HDV prevalence.
