Immunosuppressive therapy (IST) is the first-line treatment for patients with aplastic anemia (AA) who require blood transfusion when a human leukocyte antigen-matched related donor is unavailable. However, the proportion of patients with AA who are refractory to IST remains high (30%). IST in combination with eltrombopag has been studied in adults, but its efficacy and safety in children have not been established. We present three cases of AA that were initially refractory to IST but improved with additional eltrombopag administration. These patients were successfully managed using this strategy without the use of hematopoietic cell transplantation (HCT). The first patient achieved a complete response within one month after receiving eltrombopag. When the second and third patients were given eltrombopag, they were able to safely reduce the amount of cyclosporin they were given. They avoided blood transfusions, but no measurable response was obtained. The conjunctival icterus was detected and treated using a dose reduction of eltrombopag. Eltrombopag may be effective in children with AA who are refractory to IST, allowing them to avoid blood transfusions and HCT. More cases treated with this strategy are needed to confirm its efficacy and safety for children with AA.
