RESUMO
Anemia is commonly observed in patients with end-stage renal disease (ESRD) on maintenance hemodialysis (HD) and can be quite severe, particularly when there is an additional comorbidity. With the use of erythropoietin-stimulating agents (ESAs), anemia is effectively treated, but the complete normalization of hemoglobin is not recommended since these agents increase the risk of thrombosis. With improvements in the therapy of sickle cell disease (SCD), patients now survive longer and may more frequently reach end-stage renal disease and require renal replacement therapy. Their anemia can be severe but does respond to ESAs. The goal hemoglobin in these patients is not established and likely should be lower than others on maintenance hemodialysis (HD) since SCD patients already have an increased risk of thrombosis, and the use of ESAs may exacerbate this risk. We present a 57-year-old African-American female with SCD on maintenance HD admitted with an acute cerebrovascular accident (CVA) that occurred in spite of the fact that her hemoglobin was within the accepted range for the general population on maintenance HD. Her neurologic status did not improve with blood pressure control and exchange transfusions, the suggested initial therapy for an acute CVA in a patient with sickle cell disease (SCD). However, with phlebotomy, the patient's symptoms rapidly improved when her hemoglobin was lowered and subsequently maintained with a lower dose of ESAs. Our experience suggests that the hemoglobin goal in SCD patients on maintenance HD should be lower than in other HD patients. The role of phlebotomy during an acute thrombotic event needs to be explored further.
