A chance for Rituximab in Primary Biliary Cholangitis–Autoimmune Hepatitis Overlap Syndrome.

<title>Abstract</title> Autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) may coexist as an overlap syndrome, which can be challenging to diagnose and manage. In this case report, we describe a patient with AIH–PBC overlap syndrome refractory to conventional immunosuppressive therapy and with steroid-dependent disease. Rituximab was administered as rescue therapy, achieving biochemical normalization. This case supports the potential role of rituximab as a therapeutic option in patients refractory to standard immunosuppressive treatments.
