摘要:

目的 探讨血清激活素A在异位妊娠(EP)早期诊断上的价值。方法 将109例疑似EP患者根据随访结果分为EP组(62例)和宫内妊娠(IUP)组(47例)。采用酶联免疫吸附试验(ELISA)检测109例疑似EP患者的血清激活素A和β-人绒毛膜促性腺激素(β-HCG)浓度。采用受试者工作特性(ROC)曲线分析激活素A和β-HCG检测对EP的诊断价值。结果 EP组血清激活素A和β-HCG浓度明显低于IUP组(P<;0.05)。激活素A的ROC曲线下面积为0.827,高于血清β-HCG(0.710),以血清激活素A<260 pg/mL诊断EP,其灵敏度、特异性分别为85.5%、72.3%。结论 血清激活素A检测可以作为EP的早期诊断辅助指标。

Abstract:

Objective To investigate the significance of activin A in the early diagnosis of ectopic pregnancy(EP). Methods A total of 109 patients with suspected EP were classified into 2 groups according to the follow-up results:62 patients with EP and 47 patients with intrauterine pregnancy (IUP). The serum levels of activin A and beta-human chorionic gonadotropin (β-HCG) were determined in 109 patients with suspected EP by enzyme-linked immunosorbent assay (ELISA),and the receiver operating characteristic(ROC) curves were established. The diagnosis significance of activin A and β-HCG for EP was analyzed. Results The levels of activin A and β-HCG in EP group were significantly lower than those in IUP group(P<0.05). The area under ROC curves of activin A (0.827) was higher than that of β-HCG(0.710). In activin A<260 pg/mL for the diagnosis of EP,the sensitivity and specificity were 85.5% and 72.3%, respectively. Conclusions The determination of serum activin A can be considered as an early diagnosis parameter of EP.
