摘要:

目的 探讨网织红细胞(RET)各参数在新生儿溶血病(HDN)治疗中的价值,为临床判断疗效提供参考。方法 对44例HDN患者于入院当天、治疗中、出院当天3个时间点取末梢血,测定网织红细胞计数百分比(RET%)、未成熟网织红细胞百分比(IRF%)、低荧光强度网织红细胞百分比(LFR%)、中荧光强度网织红细胞百分比(MFR%)、高荧光强度网织红细胞百分比(HFR%)共5个指标,以入院当天各指标为基线,分析治疗中、出院当天各参数的变化。结果 随治疗的进行,RET%、IRF%、HFR%、MFR%呈进行性下降,LFR%呈进行性上升。RET%明显降低者占患者总数的84.09%。在明显降低组中,出院时RET%、IRF%、MFR%、HFR%与入院时相比差异有统计学意义(P<0.05),RET%下降与IRF%、HFR%下降呈正相关(r值分别为0.632、0.639,P<0.01)。在无明显降低组中,出院时RET%、IRF%、MFR%、HFR%与入院时相比,差异均无统计学意义(P>0.05)。结论 RET%可作为监测MDN治疗过程中比较敏感的指标。当RET%下降明显时,提示治疗有效。同时,IRF%、HFR%和LFR%可作为监测HDN治疗的辅助指标。

Abstract:

Objective To investigate the role of reticulocyte(RET) parameters in the treatment of hemolytic disease of newborns(HDN),and to provide a reference for evaluating treatment efficiency. Methods Peripheral blood samples of 44 patients with HDN were collected on the days of admission,treatment and discharging,respectively. All samples were determined for reticulocyte percentage(RET%),immature reticulocyte fraction percentage (IRF%),low fluorescence reticulocyte percentage (LFR%),medium fluorescence reticulocyte percentage (MFR%) and high fluorescence reticulocyte percentage (HFR%). The results on the day of admission were as baselines,and the change trend of the results on the days of treatment and discharging were evaluated. Results The RET%,IRF%,MFR% and HFR% decreased,and LFR% showed an increase with the treatment progressed. RET% was decreased,which accounted for 84.09%. In decreased group,RET%,IRF%,MFR% and HFR% on the day of discharging had statistical significance compared with those on the day of admission(P<0.05). The decrease of RET% was positively correlated with those of IRF% and HFR% in decreased group(r=0.632 and 0.639,P<0.01). There was no statistical significance for RET%,IRF%,MFR% and HFR% between the days of admission and discharging (P>0.05). Conclusions RET% could be used as a sensitive indicator in monitoring the treatment of HDN. The decreasing of RET% indicates that the treatment is effective. IRF%,HFR% and LFR% could be used as auxiliary indicators for monitoring HDN treatment.
