文题释义:
造血干细胞移植:
造血干细胞移植是通过大剂量放化疗或其他免疫抑制剂等预处理,清除受者体内的肿瘤细胞、恶性克隆细胞或异常造血干细胞,再将自体或异体造血干细胞移植给受者,使受者重建正常造血及免疫系统,从而达到治疗的目的。目前广泛应用于恶性血液病、非恶性难治性血液病、遗传性疾病和某些实体瘤治疗,已获得了较好的疗效。
造血干细胞移植的感染:造血干细胞移植后早期感染是指在移植后30 d 内发生的感染,其病因十分复杂,大多会出现多种病因同时存在的情况,导致混合感染的出现。移植的不同阶段,患者对各种病原体的易感性也不尽相同,在移植早期极易出现感染,且往往都是重症感染,相关死亡率高。造血干细胞移植感染的预防至关重要,通过科学合理的预防,可以有效降低感染的发生率及死亡率,减少患者的痛苦,提高移植效果。

 

摘要
背景:
造血干细胞移植后急性移植物抗宿主病的发生与感染有复杂的关系,控制感染能降低移植相关死亡率。
目的:探讨广谱抗菌药物对造血干细胞移植后早期感染发生的影响。
方法:收集31例行造血干细胞移植患者的临床资料,均接受自体外周血干细胞移植治疗。外周血干细胞移植后早期(30 d以内),统计观察移植后早期感染发生率和感染类型以及病原菌分布情况、治疗与转归。
结果与结论:①所有患者均顺利接受自体外周血干细胞移植治疗,造血干细胞移植后早期感染发生率为71%,未出现死亡病例;②共检出20株病原菌,其中革兰阴性菌占80%;③感染后外周血中性粒细胞数量与感染持续时间均有显著性相关性,差异有显著性意义(P < 0.01);④试验结果表明,造血干细胞移植后早期感染发生率较高,与中性粒细胞减少及恢复时间密切相关。宜在早期选择合适的广谱抗菌药物进行经验性用药,以快速、有效的控制感染。

Abstract:

BACKGROUND: Occurrence of acute graft-versus-host disease after hematopoietic stem cell transplantation is closely related to early infection, so controlling infection can decrease the transplant- related mortality.
OBJECTIVE: To explore effects of broad-spectrum antibiotics on the occurrence of early infection after hematopoietic stem cell transplantation.
METHODS: Clinical data of 31 patients undergoing autologous peripheral blood stem cell transplantation were collected. Within 30 days after cell transplantation, occurrence rate and types of early infection were detected and recorded. Besides, distribution of pathogens, as well as treatment and outcome of patients were statistically observed.
RESULTS AND CONCLUSION: All patients successfully underwent hematopoietic stem cell transplantation, and the occurrence rate of infection was 71% with no death at early stage after cell transplantation. Twenty strains of pathogens were detected, in which gram-negative bacteria accounted for 80%. In addition, there was a significant negative correlation between the number of neutrophils in the peripheral blood and the duration of infection (P < 0.01). These results indicate that the infection rate at early stage after hematopoietic stem cell transplantation is relatively higher, which is associated with reduction and recovery time of neutrophils. Therefore, it is advisable to choose appropriate broad-spectrum antibiotics for preventive treatment at early stage after cell transplantation, so as to quickly and effectively control infections.
