摘要
目的 探讨不同出生体重早产新生儿17-羟孕酮(17—OHP)分布状况,以及对筛查先天性肾上腺皮质增生症(CAH)结果的影响。方法 采用时间分辨荧光免疫分析方法检测新生儿末稍血17-OHP浓度。结果 体重〈1500g的早产新生儿17-OHP均数±SD为(63.3±16.3)nmol/L,体重1500~1999g的早产新生儿17-OHP均数±SD为(38.1±22.6)nmol/L,体重2000~2499g的早产新生儿17-OHP均数±SD为(28.1±12.7)nmol/L,体重≥2500g的早产新生儿17-OHP均数±SD为(20.8±10.2)nmol/L。正常体重组(≥2500g)的早产新生儿17-OHP值与其余三个低体重早产新生儿组比较,有显著性差异(P〈0.05)。结论 用统一17-OHP切割值〈30nmol/L对新生儿CAH筛查结果有一定的影响,建议低体重早产新生儿(〈2500g)的17-OHP切割值定为〈7Onmol/L较好,以减少假阳性率和召回率。
Objective To analyze the influence on the neonatal CAH screening by detecting 17-OHP in prematural newborns with different birth weight. Method Detect 17-OHP in neonatal capitulary blood using DELFIA method. Result The detected values of 17-OHP in prematural newborns with different birth weight are 63.3 ± 16.3 nmol/L (〈1500g). 38. 1±22.6 nmol/L (1500-1999g), 28.1± 12.7 nmol/L (2000-2499g) and 20.8±10.2 nmol/L (≥2500g) . There are significant difference between normal birth weight group and either of the three lower birth weight groups. The lower birth weight's 97thpercentile is 77.8 nmol/L, and the normal birth weight's is 42.9 nmol/Lo Conclusion Birth weight of pretural newborns makes some influence on neonatal CAN screening by detecting 17- OH Po
