Abstract |
A 12-year-old boy developed pure red cell anemia(PRCA) during a combination therapy of antiepileptic drugs(AEDs) for epilepsy. His complex partial seizure was intractable to monotherapy. During 7 months of treatment, he was treated with Vigabatrin, Carbamazepine and Valproate. While switching from Carbamazepine to Valproate, he presented anemia but with no jaundice. His hemoglobin was 4.1g/dl bone-marrow biopsy revealed erythroid hypoplasia with normal myelopoiesis and megakaryocytopoiesis, indicating PRCA. Rapid recovery from PRCA was observed 1 month after discontinuation of Valproate, without immunosuppressive therapy. Although the hematologic toxicity of AEDs is well documented, isolated cessation of red cell production is uncommon. Our observation suggests that the synergistic toxicity caused by Valproate and Carbamazepine may induce PRCA through the inhibitory effect beyond the differentiation stage of BFU-E and CFU-E. |
