| Abstract: | Various cases of myelodysplastic syndrome (MDS) with diverse immunological disorders have been reported by many investigators. In this case report, we present a 70-year-old woman who had been diagnosed as having MDS and liver cirrhosis (LC) type C for 20 months, and who finally developed autoimmune phenomena against autologous blood cells. She was admitted to our hospital in order to evaluate her advanced anemia, thrombocytopenia and fatigue. The laboratory data at admission were as follows: hemoglobin 5.3 g/dl, red blood cell count 109 x 10(4)/microliter, white blood cell count 1,760/microliter, platelet count 4.3 x 10(4)/microliter and reticulocyte count 1.3%. The direct Coombs test was positive. In addition, anti-platelet antibody was positive, using the MPHA method. With these results, Evans syndrome secondary to MDS or LC was diagnosed. The mechanisms for the development of immunological disorders in patients with MDS or LC have not been fully elucidated. To our knowledge, this patient is one of the rare cases with MDS and Evans syndrome reported in the literature. During the generation process of autoantibodies, the role of HCV antigen in the pathogenesis of Evans syndrome was of interest in this patient. |
