Basedow disease associated with Evans syndrome

摘要

A 60-year-old woman was admitted to a hospital complaining of dizziness and general fatigue in October, 2004. Because of heart failure and severe anemia, she was referred to our hospital. Based on a positive direct Coombs test and an elevated level of platelet-associated IgG (PAIgG), the patient was diagnosed as having autoimmune hemolytic anemia (AIHA) associated with idiopathic thrombocytopenic purpura (ITP), i.e., Evans syndrome. Basedow disease was also diagnosed due to hyperthyroidism with an elevation of anti-thyroid stimulating hormone (TSH) receptor antibodies. Both the Evans syndrome and Basedow disease were considerably ameliorated with plasma exchange, corticosteroid and thiamazole therapy. Although Basedow disease is known to be associated with hematological disorders such as AIHA or ITP, the combination of Basedow disease and Evans syndrome is rare. We report here a case of Basedow disease associated with Evans syndrome.
