Pulmonary hemorrhage and glomerulonephritis in primary biliary cirrhosis

We observed life-threatening intrapulmonary hemorrhages and focal proliferative glomerulonephritis in a 41-yr-old woman with primary biliary cirrhosis. The severity of the symptoms necessitated blood transfusions and mechanical ventilation; the patient improved with the help of corticosteroid therapy. No formal evidence of either Goodpasture's syndrome or any other well-defined systemic vasculitis could be found. Neutrophil cytoplasmic antibodies were initially positive and became undetectable after 3 mo of immunosuppressive treatment without relapse. This association has not been described previously and may be added to the list of extrahepatic immune-mediated conditions associated with primary biliary cirrhosis.
