BACKGROUND & AIMS: Catheter-related bloodstream infections remain the major threat for Home Parenteral Nutrition programs. Taurolidine, a potent antimicrobial agent, holds promise as an effective catheter lock to prevent such infections. Aim of the present study was to compare taurolidine with heparin, the most frequently used lock, in this respect in these high-risk patients.
Thirty patients from one referral centre for intestinal failure were enrolled after developing a catheter-related bloodstream infection. Following adequate treatment, either with or without a new access device (tunneled catheter or subcutaneous port), these patients were randomized to continue Home Parenteral Nutrition using heparin (n = 14) or taurolidine (n = 16) as catheter lock.
Whereas in controls 10 re-infections were observed, in the taurolidine group during 5370 catheter days only 1 re-infection occurred (mean infection-free survival 175 (95% CI 85-266; heparin) versus 641 (95% CI 556-727; taurolidine) days; log-rank p < 0.0001). No side effects or catheter occlusions were reported in either group. Moreover, after crossing-over of 10 patients with infections on heparin to taurolidine, only 1 new infection was observed.
Taurolidine lock dramatically decreased catheter-related bloodstream infections when compared with heparin in this high-risk group of Home Parenteral Nutrition patients.
导管相关性血流感染仍然是家庭肠外营养方案的主要威胁。牛磺罗定作为一种有效的抗菌剂,有望成为预防此类感染的有效导管封管剂。本研究旨在比较牛磺罗定与肝素(最常使用的封管剂)在这些高危患者中的效果。
30 名来自一个肠衰竭转诊中心的患者在发生导管相关性血流感染后入组。在进行适当治疗后(是否使用新的置管设备,如隧道式导管或皮下港),这些患者被随机分为肝素(n=14)或牛磺罗定(n=16)作为导管封管剂继续家庭肠外营养。
在对照组中观察到 10 例再感染,而在牛磺罗定组中,在 5370 天的导管使用中仅发生 1 例再感染(无感染生存时间的均值分别为肝素组 175(95%可信区间 85-266)天和牛磺罗定组 641(95%可信区间 556-727)天;对数秩检验 p<0.0001)。两组均未报告任何副作用或导管阻塞。此外,在将 10 例感染肝素的患者交叉至牛磺罗定组后,仅观察到 1 例新感染。
与肝素相比,牛磺罗定封管剂可显著降低家庭肠外营养高危患者的导管相关性血流感染。
