摘要:

背景:动态监测造血干细胞移植受者血浆人巨细胞病毒载量,快速筛选出早期活动性人巨细胞病毒感染者,进而指导临床用药,提高造血干细胞移植的成活率。
目的:探讨荧光定量聚合酶链反应对造血干细胞移植患者人巨细胞病毒活动性感染的早期诊断价值。
方法:收集41例造血干细胞移植患者共656份血标本,应用实时荧光定量PCR方法动态监测血浆人巨细胞病毒DNA载量,并与60例健康体检者血浆人巨细胞病毒DNA载量对比分析。
结果与结论:656份血标本中96份阳性,病毒载量介于5.0×102-1.0×107 IU/mL之间。治疗有效者人巨细胞病毒DNA迅速转阴,治疗耐药者持续阳性,12例连续阳性者2例死于巨细胞病毒活动性感染。实时荧光定量PCR方法检测人巨细胞病毒DNA适用于造血干细胞移植后巨细胞病毒活动性感染的早期诊断。

Abstract:

BACKGROUND: To improve the survival rate of transplanted hematopoietic stem cells, dynamic monitoring of plasma content of human cytomegalovirus (HCMV) and rapid screening of early active HCMV infection in hematopoietic stem cell tranplantation recipients, thus to guide the clinical medication, is preferred.
OBJECTIVE: To evaluate the usefulness of fluorescence quantitative PCR assay for early detection of HCMV activation after hematopoietic stem cell transplantation.
METHODS: Real-time fluorescence quantitative PCR assay was applied for HCMV monitoring in 656 blood samples from 41 hematopoietic stem cell tranplantation recipients and 60 control blood samples.
RESULTS AND CONCLUSION: In 656 blood samples, 96 samples were positive, and the HCMV DNA copies ranged from 5.0×102 to 1.0×107 IU/mL. Timely initiation of therapy resulted in the rapid clearance of DNA-viraemia but it recurrenced in short time by drug-resistent. Two cases from 12 postive recipients died from HCMV infection. The quantitative detection of HCMV DNA by real-time PCR is a rapid method for monitoring HCMV infection and the early diagnosis in patients after hematopoietic stem cell transplantation.
