  美国和澳大利亚学者4月4日在线发表于《乳腺癌研究和治疗》(Breast Cancer Research and Treatment)杂志的一项研究表明,定期监测高敏C反应蛋白(hs–CRP)有望用于预测曲妥珠单抗诱发的早期乳腺癌患者的无症状心脏毒性。

  该研究前瞻性地纳入了54例人表皮生长因子受体2(HER2)阳性早期乳腺癌患者,并评估了患者血清脑利钠肽(BNP)、hs-CRP和心肌肌钙蛋白I(cTnI)浓度与左心室射血分数(LVEF)显著下降的相关性。

  曲妥珠单抗诱发心脏毒性被定义为LVEF降低≥15%或LVEF<50%。

  28.6%的患者被观察到LVEF显著下降。

  hs–CRP异常(≥3mg/L)用于预测LVEF下降的敏感性为92.9 %,特异性为45.7 %;hs–CRP正常(<3mg/L)的阴性预测值为94.1 %,提示hs–CRP正常可能与此后LVEF下降风险低有关;但是,研究未观察到BNP或cTnI与LEVF下降有关。

心力衰竭病人恶化和低水平的维生素C和高水平hs-CRP相关

2011年美国心脏协会会议报道,低水平的维生素C与高水平的高敏C-反应蛋白(hs-CRP)和短期无主要心脏问题或心力衰竭病人的死亡有关。     与食物中摄入高含量维生素C的人群相比,研究中低维生素C摄入的心力衰竭病人,可能具有2.4倍高水平的hsCRP,是炎症和心脏疾病危险因素的指标。这项研究首次证明,低维生素C摄入量与心力衰竭病人的糟糕结果有关。
