Patients with immune thrombocytopaenia (ITP) have a wide spectrum of disease severity and bleeding risk even at similar platelet counts. Hence, additional clinical and laboratory factors may be considered in the evaluation of bleeding risk in ITP. Risk stratification based on predicted bleeding risk may help to identify high-risk patients and guide the initial management of ITP in adults requiring treatment. Recent evidence supports the use of high-dose dexamethasone therapy over prednisone in the initial management of ITP because of improved initial response rates, shorter median time to response and better safety profile. A risk-stratified approach to management of ITP is hoped to reduce bleeding complications in high-risk patients; however, the outcomes of such management approach need to be studied prospectively. Additionally, whether therapy intensification or combination of dual therapy such as intravenous immunoglobulin or rituximab in combination with dexamethasone can reduce bleeding complications in high-risk ITP should be studied in the future.
患有免疫性血小板减少症 (ITP) 的患者即使血小板计数相似,其疾病严重程度和出血风险也存在广泛差异。因此,在评估 ITP 的出血风险时可能需要考虑其他临床和实验室因素。基于预测出血风险的分层可以帮助识别高危患者,并指导需要治疗的成人 ITP 的初始管理。最近的证据支持在 ITP 的初始管理中使用高剂量地塞米松治疗而不是泼尼松,因为其初始缓解率更高、达到缓解的中位时间更短且安全性更好。对 ITP 的管理进行分层处理有望减少高危患者的出血并发症;然而,需要前瞻性地研究这种管理方法的结果。此外,将来需要研究在高危 ITP 中强化治疗或双重治疗(如静脉注射免疫球蛋白或利妥昔单抗联合地塞米松)是否可以减少出血并发症。
