A case of Evans syndrome

Evans syndrome is an autoimmune disorder described by Robert Evans in 1951 specifying that a link exists between primary thrombocytopenic purpura and acquired haemolytic anaemia. It is a rare autoimmune disorder characterised by the simultaneous or sequential development of autoimmune haemolytic anaemia (AIHA) and immune thrombocytopenia (ITP) with or without immune neutropenia. Approximately, Evans syndrome represent 5-10% of warm autoimmune haemolytic anaemia cases and 2-5% of ITP cases. It is basically a diagnosis of exclusion. We present a 50-year-old female presented with anaemia, jaundice and petechia. Patient indirect bilirubin was raised, Coombs test was positive, lactate dehydrogenase and reticulocyte count were raised. Based on the Coombs positive haemolytic anaemia and thrombocytopenia patient was diagnosed with Evans syndrome. ANA profile was positive for SS-A suggestive of underlying autoimmune disorder. Evans syndrome is difficult to diagnose and treat. Typically, corticosteroids and other immunosuppressive medications are used to manage the syndrome.
