摘要
目的:探究硫酸多粘菌素B对血液病中性粒细胞缺乏伴发热患者的临床疗效与安全性。方法:收集2019年10月-2020年9月在福建医科大学附属协和医院血液科住院的50例患者的临床资料,所有患者均接受联合或大剂量化疗或造血干细胞移植后出现中性粒细胞缺乏伴发热,经验性抗感染治疗疗效不佳,病原学检查阳性并根据药敏结果更改为硫酸多粘菌素B为主的方案进行抗感染治疗。结果:50例患者总共发生85例次感染,感染部位分别为肺部、血流、肠道、口腔、肛周、软组织以及鼻腔,致病菌以革兰阴性菌为主。根据病原学及药敏结果更改为硫酸多粘菌素B抗感染治疗,总有效率为68%,特别是用药>7 d有效率明显上升,自动出院及死亡患者分别占24%及8%。碳青霉烯类抗菌素使用时间在14 d内或是7 d内更改为硫酸多粘菌素B治疗的有效率分别为80%及70.6%,2周后再更改的患者有效率仅为33.3%;替加环素使用时间在14 d内或是7 d内更改为硫酸多粘菌素B治疗的有效率分别为80%及66.7%。硫酸多粘菌素B不良反应发生率低,多数轻微,仅1例患者出现横纹肌溶解。结论:硫酸多粘菌素B对于血液病中性粒细胞缺乏伴发热患者临床疗效好,且安全性高。
Objective: To observe the clinical efficacy and safety of polymyxin B sulfate in febrile neutropenia patients with hematonosis. Methods: Clinical data of 50 patients in the department of hematology, Fujian Medical University Union Hospital from October 2019 to September 2020 were collected. All the patients developed febrile neutropenia after chemotherapy or hematopoietic stem cell transplantation. According to the results of drug susceptible test, polymyxin B sulfate was administrated mainly when the empirical antimicrobial treatments was poor and the pathogenic microbes test was positive. Results: A total of 85 times of infection occurred in 50 patients. The infection sites were lung, blood flow, intestinal tract, oral cavity, perianal, soft tissue and nasal cavity. Gram negative bacteria was the main pathogenic microbe. After administration of polymyxin B sulfate when the etiology was confirmed, the total effective rate was 68%,especially the effective rate increased significantly after more than 7 days of polymyxin B sulfate treatment. Also, 24%and 8% of the patients were discharged automatically and died respectively. The effective rate of patients receiving carbapenem antibiotics changed to polymyxin B sulfate within 14 or 7 days was 80% and 70.6%, respectively, while the effective rate of patients who changed after 2 weeks was only 33.3%. The effective rate of patients receiving tigecycline changed to polymyxin B sulfate within 14 or 7 days was 80% and 66.7%, respectively. The incidence of adverse reactions of polymyxin B sulfate was low, most of which were mild, and only one patient occurred rhabdomyolysis.Conclusion: Polymyxin B sulfate has good clinical efficacy and safety in febrile neutropenia patients with hematonosis.
