【摘要】 目的:探讨RDW和HGB检测对儿童巨细胞病毒感染的临床意义。方法:回顾性分析94例初检CMV IgM阳性患儿的病历资料和全血RDW、HGB数据。选择同期211例小儿外科CMV IgM阴性且无其他病原感染临床症状患儿作为对照。对转阴前后RDW、HGB数据进行对比分析。结果:巨细胞病毒感染患者全血RDW为13.85%(12.67%,15.33%),显著高于对照组的13.30%(12.94%,13.67%),差异有统计学意义(Z=-2.709,P<0.01);感染者全血HGB为112.90(103.73,120.85)g/L,显著低于对照组的126.80(120.40,131.50)g/L,差异有统计学意义(Z=-7.697,P<0.01)。17例患者治疗前后RDW、HGB比较差异均有统计学意义(Z=-2.446,P<0.05;Z=-2.033,P<0.05)。结论:RDW和HGB检测对儿童巨细胞病毒感染诊断、病情监测及预后有一定的临床意义,也提示HCMV对红系造血系统可能有明显的影响。

【Abstract】 Objective:To investigate the clinical significance of RDW and HGB detection in children with cytomegalovirus infection.Method:A retrospective analysis was performed on the medical records and RDW and HGB data of 94 cases of primary CMV IgM positive children.In the same period,211 cases of pediatric surgery with CMV IgM negative and no clinical symptoms of other pathogenic infections were selected as controls.17 patients with cytomegalovirus infection,after treatment of CMV IgM negative,the RDW and HGB data were compared before and after analysis.Result:The RDW of whole blood in patients with cytomegalovirus infection was 13.85%(12.67%,15.33%),which was significantly higher than 13.30%(12.94%,13.67%) in the control group,the difference was statistically significant(Z=-2.709,P<0.01).HGB of infected whole blood was 112.90(103.73,120.85)g/L,which was significantly lower than 126.80(120.40,131.50)g/L of the control group,and the difference was statistically significant(Z=-7.697,P<0.01).The RDW and HGB were analyzed before and after treatment in 17 patients,and the differences were statistically significant(Z=-2.446,P<0.05;Z=-2.033,P<0.05).Conclusion:RDW and HGB test have certain clinical significance for the diagnosis of CMV infection in children,condition monitoring and prognosis.It also suggests that HCMV may have a significant effect on erythroid hematopoietic system.

人巨细胞病毒(HCMV)感染在我国人群中十分普遍,儿童是该病毒原发感染的最主要人群[1]。自20世纪60年代起,临床发现HCMV感染患者可伴有血小板、粒细胞减少、异常淋巴细胞增殖及贫血等造血系统异常的表现[2]。但相当一段时间里,HCMV与造血关系未受到足够关注。红细胞分布宽度(RDW)是全血细胞分析中的常规检测指标,是反映红细胞体积大小变异性的参数,主要用于贫血的相关分析,RDW是检测红细胞大小异质性的指标,对缺铁性贫血与球蛋白生成障碍性贫血的鉴别有重要意义[3]。HGB是人體有核红细胞及网织红细胞内合成的一种含色素辅基的结合蛋白质,是红细胞内的运输蛋白,其判断贫血程度优于红细胞计数。目前国内鲜见用RDW和HGB检测指标反映巨细胞病毒感染的血液动态变化,通过检测两者可提示患者骨髓红系功能受抑及恢复的情况,本研究将对此进行探究。
