artesunate anemia

  • delayed hemolytic events occur in ≈20% of patients with severe imported malaria, and 60% of these patients require blood transfusion
  • Delayed-onset anemia (herein referred to as postartesunate delayed-onset hemolysis [PADH] pattern of anemia) has been observed to occur 2–3 weeks after initiation of IV artesunate
  • The mechanism of this anemia is hemolytic, as demonstrated by high serum lactate dehydrogenase (LDH) and low plasma haptoglobin levels

  • this side effect is associated with artesunate
  • PADH occurred in 27% of patients in this study, but it was rarely associated with severe anemia and was never fatal
  • median delayed drop in hemoglobin levels was 1.3 g/dL
  • This transfusion rate (<5%) is markedly lower than that previously reported for patients with severe imported malaria and delayed-onset anemia (≈60%)
  • Side effects of artesunate frequently include gastrointestinal disturbances, neutropenia (1.3%), reticulocytopenia (0.6%), and elevated liver enzymes (1.1%)
