What this trial studies

This observational study aims to assess the prevalence of hepatitis Delta virus (HDV) infections and the prognosis of affected patients in southeastern Turkey. The investigators will conduct training sessions for 250 family physicians across Diyarbakir, Batman, Mardin, and Sanliurfa to enhance their ability to diagnose and manage hepatitis B virus (HBV), HDV, hepatitis C virus (HCV), and HIV infections. The study will also evaluate liver fibrosis in patients with HDV using non-invasive methods and will focus on understanding co-infections and vertical transmission rates. The ultimate goal is to contribute to the national hepatitis elimination program.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have been HBsAg positive for at least six months.

Not a fit: Patients who are not HBsAg positive or are under 18 years old may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnosis and management of HDV infections, ultimately enhancing patient outcomes in Turkey.

How similar studies have performed: While this approach is focused on a specific regional prevalence assessment, similar studies in other regions have shown success in improving hepatitis management and awareness.
