Chronic active hepatitis with histological features of primary biliary cirrhosis.
A 51-year-old woman was evaluated because of Raynaud's phenomenon, Sjögren's syndrome, and general malaise. There was neither skin itching nor jaundice. Endoscopic retrograde cholangiopancreatography showed a normal extrahepatic as well as intrahepatic biliary tree. Serum GOT and GPT fluctuated with episodes of marked increases. The alkaline phosphatase was slightly increased and total cholesterol was normal. There were marked increases of IgG and IgM. AMA was positive at a titer of 1:320, which was measured by an indirect immunofluorescence method. PBC-specific AMA (anti-M2) was positive, but mixed-form AMA (anti-M4) negative. An LE-cell test, ASMA, ANA, and anti-DNA antibody were all positive on several repeated tests. A wedge liver biopsy tissue showed mixed features of PBC and CAH. A diagnosis of CAH was made on the basis of the clinical, serological, and morphologic findings. The patient responded well to prednisolone treatment with prominent improvement of her symptoms and liver function tests. Subsequently, AMA fell to undetectable levels by indirect immunofluorescence method.
