What this trial studies
This study aims to evaluate and follow patients with acute and chronic liver diseases, including hepatitis B, C, and D. Participants will undergo routine check-ups, including blood and urine tests, and liver ultrasounds. They will be followed up annually for similar evaluations, with additional tests such as biopsies and genetic analyses potentially requested. The goal is to collect data and samples to better understand the natural history and pathogenesis of liver diseases.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and treatment options for patients with liver diseases.
How similar studies have gone: Other studies have successfully utilized similar observational approaches to understand liver diseases, indicating potential for valuable insights.
