A 50-year-old woman, who had been diagnosed as having rheumatoid arthritis (RA) 7 months earlier, was admitted to our hospital because of liver dysfunction. Her laboratory data and histological findings satisfied the criteria for autoimmune hepatitis (AIH) as revised by the International AIH Group. Laboratory examinations (indirect immunofluorescence and immunoblotting analyses) revealed that anti-Golgi complex antibodies (AGA) were positive in her serum. AGA are thought to be closely associated with AIH and/or liver dysfunction according to several reports.
