Pure red cell aplasia associated with autoimmune hepatitis successfully treated with cyclosporine A.

A 47-year-old female with a 17-year history of autoimmune hepatitis had been treated with prednisolone, azathioprine, and ursodeoxycholic acid. Although her alanine aminotransferase level occasionally showed mild abnormality, the prednisolone dose could not be increased because she had developed cataract during the course of her illness. In May 2012, she developed severe normochromic normocytic anemia without hemorrhage, and azathioprine was discontinued because it was suspected of being the cause.
