Core Tip
Core Tip: This study reports, for the first time, two patients with hepatitis D virus (HDV)-hepatitis B virus co-infection combined with autoimmune hepatitis (AIH) who were not treated with interferon and achieved serological conversion and histological remission with antiviral drugs (entecavir/tenofovir alafenamide) in combination with immunosuppression (prednisone + azathioprine). Patients with severe HDV-related liver disease should be routinely screened for autoantibodies to avoid exacerbation by interferon therapy. The combination therapy was effective in controlling HDV-hepatitis B virus co-infection associated AIH, suggesting that aberrant immunoregulation may be an important mechanism of HDV-induced AIH, providing new evidence for elucidating the pathogenesis of this complex disease, and emphasizing the necessity of immune mechanism research.
