Pulmonary hypertension associated with liver cirrhosis and hepatitis-B antigenemia.
An autopsy case of pulmonary hypertension in a 29-year-old Japanese female with macronodular, posthepatic liver cirrhosis and hepatitis-B antigenemia was presented. No recognizable known cardio-pulmonary disease or portal thrombosis was obtained. Hepatitis-B antigen was demonstrated in the cirrhotic hepatocytes by a specific peroxidase antiperoxidase method. Characteristic pulmonary arterial changes including plexiform lesions with varying developmental stages were widely observed throughout the lungs. Complication of these two distinct disease processes seems to be rarely encountered in the literature. Discussion was focused on the possible interrelationship between the liver cirrhosis with hepatitis-B antigenemia and pulmonary hypertension. Proposed were presumptive underlying humoral, particularly immunological, abnormalities common to these diseases rather than mere incidental complications.
