Bacteremia is a leading cause of morbidity and mortality in children undergoing hematopoietic cell transplantation (HCT). Infections of vancomycin-resistant enterococci (VRE) and multidrug resistant (MDR) gram-negative rods (GNRs) are common in this population. Our objective was to assess whether experimental bath wipes containing silver were more effective than standard bath wipes containing soap at reducing skin colonization by VRE and MDR GNRs, and nonmucosal barrier injury bacteremia. Patients undergoing autologous or allogeneic HCT in a tertiary referral center were randomized to receive experimental or standard bath wipes for 60 days post-HCT. Skin swabs were collected at baseline, discharge, and day +60 post-HCT. The rate of VRE colonization was chosen as the marker for efficacy. Experimental bath wipes were well tolerated. Before the study, the rate of colonization with VRE in HCT recipients was 25%. In an interim analysis of 127 children, one (2%) patient in the experimental arm and two (3%) in the standard arm were colonized with VRE. Two (3%) patients had nonmucosal barrier injury bacteremia in the standard arm, with none in the experimental arm. MDR GNRs were not isolated. The trial was halted because the interim analyses indicated equivalent efficacy of the two methods. Skin cleansing with silver-containing or standard bath wipes resulted in very low and equivalent rates of bacteremia and colonization with VRE and MDR GNRs in children post-HCT. Future studies in other high-risk populations are needed to confirm these results.
菌血症是造血细胞移植(HCT)患儿发病和死亡的主要原因。该人群中耐万古霉素肠球菌(VRE)和多药耐药(MDR)革兰氏阴性菌(GNR)感染很常见。我们的目的是评估含银实验浴巾是否比含皂标准浴巾更能有效减少 VRE 和 MDR GNR 皮肤定植和非黏膜屏障损伤菌血症。在三级转诊中心接受自体或同种异体 HCT 的患者被随机分配接受实验或标准浴巾,在 HCT 后 60 天内使用。在基线、出院和 HCT 后第 60 天收集皮肤拭子。VRE 定植率被选为疗效标志物。实验浴巾耐受性良好。在研究之前,HCT 受者中 VRE 定植率为 25%。在对 127 名儿童的中期分析中,实验组 1 名(2%)和标准组 2 名(3%)患者定植 VRE。标准组有 2 名(3%)患者发生非黏膜屏障损伤菌血症,实验组无患者发生。未分离出 MDR GNR。由于中期分析表明两种方法的疗效相当,试验停止。含银或标准浴巾进行皮肤清洁后,HCT 后儿童的菌血症和 VRE 及 MDR GNR 定植率非常低且相当。需要在其他高危人群中进行进一步研究以证实这些结果。
