Immunological studies in familial primary biliary cirrhosis.
Tests for cell-mediated immunity and presence of autoantibodies were performed in a mother and daughter with primary biliary cirrhosis. Lymphocytes transformation to phytohemagglutinin, delayed cutaneous response to one or more skin test antigens, and percentage of peripheral T and B lymphocytes were normal in both patients. Although successful in the mother, dinitrochlorbenzene sensitization was not achieved in the daughter. Histocompatibility antigens 1 and 8, elevated levels of IgM, and antibodies to mitochondria, smooth muscle, and skeletal muscle were present in both patients. However, the clinical course was more severe in the daughter who developed portal hypertension with bleeding esophageal varices requiring portacaval anastomosis. Except for intermittent pruritus, the mother has remained asymptomatic.
