RESUMO
BACKGROUND: Thrombopoietin receptor agonists are emerging as a therapeutic option for patients with aplastic anemia (AA) and myelodysplastic syndrome (MDS). We report our experience of treating children with AA/MDS with romiplostim, thrombopoietin receptor agonist. OBSERVATIONS: Three children (AA, 2; MDS, 1) received romiplostim treatment at a median dose of 10 µg/kg/week (starting dose: 5 µg/kg/wk; 2.5 µg/kg/wk increment). Trilineage hematopoietic recovery occurred at a median of 13 weeks (range: 13 to 16 wk) without adverse events. Hematopoiesis continued to improve after therapy discontinuation (median follow-up: 2.8 y; range: 0.5 to 3.0). CONCLUSION: Our experience supports the short-term safety and efficacy of romiplostim in children with AA/MDS.
