研究认为,左氧氟沙星治疗可预防儿童急性白血病强化化疗后细菌血症感染风险

儿童急性白血病和造血干细胞移植(HSCT)患者中,细菌血症的发病风险较高。近日研究人员考察了左氧氟沙星预防急性白血病和HSCT后细菌血症的疗效和安全性。

年龄在6个月-21岁的白血病(急性髓系白血病或复发的急性淋巴细胞白血病)化疗患者以及接受HSCT患者参与研究。白血病组患者在2轮化疗期间接受左氧氟沙星预防(n?=?100)或对照(n?=?100);HSCT组接受移植治疗期间接受预防(n=210)或对照(n=214)。研究的主要终点为细菌血症发生率,次要终点包括发热、中性粒细胞减少、严重感染、侵袭性真菌病、艰难梭菌相关性腹泻和肌肉骨骼毒性效应。

总计624名患者参与研究,其中白血病化疗组200人,HSCT组424人。对于白血病化疗组,接受左氧氟沙星预防后细菌血症发生率显著降低(21.9% vs 43.4%),而HSCT组感染风险降低但差异不显著(11.0% vs 17.3%)。左氧氟沙星预防治疗患者发热和中性粒细胞减少风险降低(71.2% vs 82.1%),但组间严重感染、侵袭性真菌感染、艰难梭菌相关性腹泻和肌肉骨骼毒性效应差异不显著。

研究认为,左氧氟沙星治疗可预防儿童急性白血病强化化疗后细菌血症感染风险。
