目的 :检测正常妊娠和子痫前期孕妇在早期妊娠时血清胎儿血红蛋白(HbF)、总血红蛋白(HbT)水平,探讨母血HbF/HbT比值是否可作为预测孕妇发生子痫前期的标志物。方法:ELISA检测38例正常妊娠妇女、51例子痫前期孕妇妊娠早期血清HbF和HbT水平,比较两组血清HbF和HbT的水平。结果:子痫前期组血清HbF浓度明显高于正常妊娠组[(1.41±0.92)μg/L vs(0.53±0.76)μg/L,P<0.01)];血清HbF/HbT明显高于正常妊娠组(0.008 1±0.005 2 vs 0.002 5±0.001 6,P<0.01)。在妊娠早期,HbF/HbT比值>0.003 0时,预测子痫前期的敏感性为82.4%,特异性为78.9%。结论:妊娠早期血清HbF/HbT比值可以作为预测子痫前期的标志物。
Objective: To detect the serum levels of fetal hemoglobin (HbF) and total hemoglobin (HbT) in normal pregnancy and preeclampsia pregnant women and to explore whether the maternal serum HbF / HbT ratio can be used as a marker of preeclampsia in pregnant women. Methods: Serum levels of HbF and HbT in 38 normal pregnant women and 51 pregnant women with preeclampsia were detected by ELISA. The levels of serum HbF and HbT in the two groups were compared. Results: The serum HbF level in preeclampsia group was significantly higher than that in normal pregnancy group [(1.41 ± 0.92) μg / L vs (0.53 ± 0.76) μg / L, P <0.01). The serum HbF / HbT level was significantly higher than that in normal pregnancy group (0.008 1 ± 0.005 2 vs 0.002 5 ± 0.001 6, P <0.01). In the first trimester of pregnancy, the sensitivity of pre-eclampsia was 82.4% and the specificity was 78.9% at a HbF / HbT ratio> 0.003 0. Conclusion: The serum HbF / HbT ratio in early pregnancy can be used as a marker of preeclampsia.
