In this article, we describe the case of a fi fty-year-old patient with autoimmune hemolytic anemia (AIHA) with constitutional symptoms, jaundice, unquantifi ed fever and progressive dyspnea.The patient had history of smoking and Hepatitis A and following a physical exam she was found in a regular condition, icteric but with no other further signs.Her laboratory tests revealed hemolytic anemia with a hemoglobin of 8.5 g/dL, an increase of total and indirect bilirubin, an elevated ferritin, a decreased transferrin and haptoglobin and a positive result for direct Coomb's test.Considering this, an immune profi le was ordered fi nding a negative result of ANAs and ENAs and a decrease of complement C3 and C4.The patient was diagnosed with AIHA and as an initial step a corticosteroid treatment was administrated however the patient showed no clinical nor chemical improvement.At her third day of hospitalization, she was unstable hemodynamically requiring transfer to Intensive Care Unit (ICU) to optimize management.After 24 hours on ICU, due to persistence of deterioration of the patient, it was decided to manage with erythropoietin (EPO).In the following days, the patient showed a rise in her hemoglobin and an overall improvement made possible the transfer to hospitalization service.The AIHA is an uncommon disease and is not the fi rst option that comes to mind with these symptoms, currently there are not controlled studies to the treatment due to its complexity and the heterogeneity of the results.We strongly support the use of EPO in refractory cases of this pathology.
