Hepatology:抗血小板治疗会降低慢性乙肝患者HCC风险吗?

2017-11-21 吴星 环球医学

2017年11月,发表在《Hepatology》上的一项回顾性分析,考察了抗血小板治疗是否会降低慢性乙型肝炎患者的肝细胞癌(HCC)风险。分析结果表明:抗血小板治疗会降低乙型肝炎病毒被有效抑制的慢性乙型肝炎患者HCC风险。但包含氯吡格雷的抗血小板治疗会增加出血风险。

抗血小板治疗已经在临床前研究中表现出对HCC的保护作用。然而,抗血小板治疗是否会降低慢性乙型肝炎患者的风险是未知的。研究人员进行了1674例慢性乙型肝炎患者数据的回顾性分析,这些患者于2002年1月~2015年5月入组,血清乙型肝炎病毒DNA水平被抗病毒药物抑制到低于2000IU/mL。首要和次要结局分别为HCC的发生和出血事件。使用总人群的时变Cox成比例风险模型和倾向得分匹配分析对接受抗血小板治疗(阿司匹林、氯吡格雷或二者联合;抗血小板组)和未接受(非抗血小板组)治疗的患者进行了风险比较。抗血小板组纳入了558例患者,非抗血小板组为1116例。研究期间,63例患者(3.8%)发生HCC。时变Cox成比例分析中,抗血小板组的HCC风险显着性低(HR,0.44;95% CI,0.23~0.85;P=0.01),不管是用何种抗血小板药物。倾向得分匹配对中,抗血小板治疗显着降低HCC风险(0.34;0.15~0.77;P=0.01)。但是,总体出血风险抗血小板组较高(3.28;1.98~5.42;P<0.001),尤其是氯吡格雷联合或不联合阿司匹林。单独使用阿司匹林与较高的出血风险不相关(1.11;0.48~2.54;P=0.81)。

结论:抗血小板治疗会降低乙型肝炎病毒被有效抑制的慢性乙型肝炎患者HCC风险。但是,包含氯吡格雷的抗血小板治疗会增加出血风险。
