Case Report: A case of pediatric persistent refractory ITP responsive to avatrombopag

Immune thrombocytopenia (ITP) is a rare hematologic disorder characterized by low platelet counts due to an immune-mediated destruction of platelets. While corticosteroids, intravenous immunoglobulin (IVIG) are the mainstays of treatment, a subset of patients may remain refractory to these therapies. Here, we present a case of a 6-year-old girl diagnosed with refractory ITP, who failed to respond to standard therapies but showed a remarkable clinical improvement with avatrombopag, a thrombopoietin receptor agonist.
