新生儿脐血红细胞葡萄糖6磷酸脱氢酶缺乏筛查结果分析

目的 了解广东省东莞市莞城地区新生儿脐血红细胞葡萄糖6磷酸脱氢酶(G-6-PD)缺乏的发生率。方法 9676例活产新生儿生后即取脐血，采用定量法测定红细胞G6PD／6PGD的比值。低于1．0者为G-6-PD缺乏。结果 测得G-6-PD缺乏的患儿265例，总发生率为2．74％。其中男230例，发生率为4．07％；女35例，发生率为0．87％。男性发生率明显高于女性(χ^2=90．75，P＜0．001)。结论 脐血G-6-PD活性筛查，能比较准确地检测出G-6-PD缺乏患儿，指导临床对其并发症进行早期干预，避免智力低下等后遗症的发生，提高人口素质。

Analysis on screening of cord blood specimens for G-6-PD deficiency

Objective To explore the incidence of G-6-PD deficiency in Dongguan District,Dongguan,Guangdong province. Methods Cord blood was obtained in 9676 cases of live births. G6PD/6PGD ratio was measured. Results Two hundred and sixty-five cases were diagnosed as G-6-PD deficiency giving an incidence of 2.74%. The incidence in male (4.07%,230/5646) was significantly higher than that in female (0.875,35/4030) ( P <0.001). Conclusions Screening of G-6-PD can detect infants who suffer from G-6-PD deficiency,which can provide earlier precautions for clinicians.
