Subtle presentation of active primary biliary cirrhosis in chronic hepatitis B: a case report.

We are describing an interesting case of two chronic liver diseases in a 48-year-old Chinese woman. While chronic hepatitis B is a common entity in Asia, the patient was later found to have active, asymptomatic primary biliary cirrhosis due to a persistently elevated alkaline phosphatase level after optimal hepatitis B virus DNA suppression on antiviral therapy. This report emphasizes the importance of keeping a high index of suspicion for another potential liver disease process even after a patient has been successfully treated for a primary liver condition. Clinical vigilance, especially in atypical clinical presentations, can result in early accurate diagnosis and prompt treatment.
