基线临床特征与重度持续性甲旁亢的关系

血液透析患者继发性甲状旁腺功能亢进(sHPT)的临床病程未被很好描述,而且,拟钙剂西那卡塞对sHPT疾病进展的影响尚不确定。为了描述接受磷酸盐结合剂和/或维生素D治疗患者的sHPT临床病程,以及西那卡塞对重度持续性HPT(定义为持续性甲状旁腺激素(PTH)浓度显著升高伴高钙血症或甲状旁腺切除)发生的影响,来自加拿大纽芬兰纪念大学Patrick S Parfrey教授及其团队进行了一项研究,该研究发现重度持续性HPT常在血液透析患者中发生,西那卡塞治疗可大幅减少其发生。该研究结果发表在2013年10月9日的The Journal of Clinical Endocrinology & Metabolism杂志上。【原文下载】

该研究是一项随机、双盲、安慰剂对照临床试验,在全球多个中心进行。从5755例血液透析患者中筛选3883例中到重度sHPT患者。主要评价指标包括:甲状旁腺切除术、重度持续性HPT、以及商品化西那卡塞的使用。干预措施包括:西那卡塞(每日30至180mg)或安慰剂治疗64个月。

该研究结果表明,1935例随机分配到安慰剂组的患者中,278例(14%)患者接受甲状旁腺切除术(手术前12月中PTH中位数为1872pg/ml)。年龄、性别、地域、合并症、钙(包含磷酸盐结合剂)的使用、以及基线血钙、血磷和PTH浓度与甲状旁腺切除术有关。443例(23%)例患者起始商品化西那卡塞治疗(治疗起始前PTH中位数为1108pg/ml)。

470例(24%)患者发生重度持续性HPT。在多元COX模型中,重度持续性HPT的相对危险度(随机分配到西那卡塞组的患者与随机分配到安慰剂组患者比较)为0.31(95%CI 0.26至0.37)。当校正基线临床特征后,这个相对危险度稍有差异。

该研究发现,重度持续性HPT常在血液透析患者中发生,而常规治疗和西那卡塞可大幅减少其发生。

FDA暂停盐酸西那卡塞儿童试验

  根据2013年2月26日美国食品与药物管理局(FDA)官方网站消息,FDA已暂停了盐酸西那卡塞(商品名Sensipar,通用名cinacalcet hydrochloride)的所有儿童试验,原因是最近出现了14岁儿童死亡案例。目前尚未确定西那卡塞是否导致了患者死亡。   FDA建议,医生应监测患者的血清钙水平。在启动盐酸西那卡塞治疗或调整其剂量后1周内评估患者的血清钙水平,
