Lancet oncol:骨髓瘤患者预防性应用左氧氟沙星可降低发热和死亡率

2019-10-24 QQY MedSci原创

骨髓瘤可引发严重的免疫缺陷和复发性重度感染。英国每年约有5500例新确诊的骨髓瘤,其中1/4患者在确诊3个月内会发生重度感染。予以新确诊的骨髓瘤患者抗生素预防,是否可有效预防感染?研究人员对此展开研究,同时评估抗生素预防对新确诊的骨髓瘤患者抗生素耐药性和卫生保健相关感染的影响。本研究是一个前瞻性的多中心的、双盲的安慰剂为对照的随机试验,招募年满21岁的新确诊的骨髓瘤患者,所有患者在被招募后14天内

骨髓瘤可引发严重的免疫缺陷和复发性重度感染。英国每年约有5500例新确诊的骨髓瘤,其中1/4患者在确诊3个月内会发生重度感染。予以新确诊的骨髓瘤患者抗生素预防,是否可有效预防感染?研究人员对此展开研究,同时评估抗生素预防对新确诊的骨髓瘤患者抗生素耐药性和卫生保健相关感染的影响。

本研究是一个前瞻性的多中心的、双盲的安慰剂为对照的随机试验,招募年满21岁的新确诊的骨髓瘤患者,所有患者在被招募后14天内即展开针对骨髓瘤的治疗。将受试者按1:1随机分至左氧氟沙星组(500mg,口服,1/日)或安慰剂组,持续12周。主要结点是12周内的首次发热或全因死亡。

2012年8月15日-2016年4月29日,共招募了977位患者,489位被分至左氧氟沙星组,488位被分至安慰剂组。中位随访12个月(IQR 8-13)。左氧氟沙星组和安慰剂组分别有95位(19%)和134位(27%)患者出现发热或死亡(风险比 0.66,95% CI 0.51-0.86,p=0.0018)。截止治疗开始后16周时,共记录了597例重度不良事件(左氧氟沙星组和安慰剂组分别有308例[52%]和289例[48%])。除了左氧氟沙星组有5例(1%)可逆性肌腱炎外,两组间的重度不良事件相似。

与安慰剂相比,在活动性骨髓瘤治疗的前12周中,添加预防性左氧氟沙星治疗可显著减少发热事件和死亡,而且不会增加卫生保健相关感染。本研究结果提示,可给予正在抗骨髓瘤治疗的新确诊的骨髓瘤患者预防性的应用左氧氟沙星。
