引言和背景

免疫性血小板减少症(ITP)是一种自身免疫性疾病,其特征是由于过度破坏和生成受损导致血小板计数下降,从而增加出血风险。虽然通常具有自限性,但中度至重度血小板减少或有出血症状的儿童需要及时治疗以防止出血并发症。标准的一线治疗通常包括糖皮质激素和静脉注射免疫球蛋白(IVIG),旨在调节免疫反应并增加血小板计数。然而,一部分患者会复发或无法达到持久缓解。

艾曲波帕是一种小分子血小板生成素(TPO)受体激动剂,模拟内源性TPO刺激血小板生成。尽管已获美国食品药品监督管理局批准用于慢性儿童ITP,但在新诊断病例中的作用尚未确定。为了填补这一空白,最近的PINES试验调查了早期使用艾曲波帕是否能改善需要药物干预的新诊断ITP儿童的治疗结果。
