Thrombocytopenia is common in patients with advanced liver disease. These patients frequently require invasive diagnostic or therapeutic procedures in the setting of thrombocytopenia. A common platelet goal before such procedures is ≥50,000/μL, but target levels vary by provider and the procedure. Platelet transfusion has disadvantages, including safety and cost. No other short-term options for ameliorating thrombocytopenia before procedures were available until the thrombopoietin receptor agonists were recently approved. Avatrombopag and lusutrombopag can be used in certain patients with thrombocytopenia due to advanced liver disease undergoing elective invasive procedures; these new agents are highly effective in carefully selected patients, and real world data of safety and efficacy are awaited.
血小板减少症在晚期肝病患者中很常见。这些患者在血小板减少的情况下经常需要进行侵入性诊断或治疗程序。此类程序前常见的血小板目标是≥50,000/μL,但目标水平因医疗服务提供者和程序而异。血小板输注有缺点,包括安全性和成本。在血小板生成素受体激动剂最近获批之前,尚无其他在程序前改善血小板减少症的短期选择。阿伐曲泊帕和芦曲泊帕可用于某些因晚期肝病接受择期侵入性程序而出现血小板减少症的患者;这些新药在精心挑选的患者中非常有效,安全性和疗效的真实世界数据有待观察。
