摘要:

目的 探讨补体C3对冻融胚胎移植(F-ET)妊娠结局的早期预测价值。 方法 前瞻性收集378个F-ET周期相关资料,依据补体C3预测F-ET妊娠结局的最佳截断值分为A组(补体C3 ≤ 1.05)120个周期;B组(补体C3 > 1.05)258个周期,比较两组结局。分析B组补体C3预测F-ET自然流产的最佳截断值。 结果 年龄是F-ET妊娠成功的危险因素(P < 0.05);补体C3和胚胎类型是F-ET妊娠成功的保护因素(P < 0.05)。补体C3对F-ET妊娠结局的受试者工作特征曲线(ROC)曲线下面积为0.702, 最佳截断值为1.05 g/L,其预测临床妊娠灵敏度为87.60%、特异度为52.00%。B组临床妊娠率(67.05%)和胚胎着床率(52.75%)明显高于A组,差异有统计学意义(P < 0.05)。补体C3早期预测F-ET后自然流产最佳截断值为1.32 g/L,ROC曲线下面积为0.760,灵敏度为69.00%、特异度为81.20%。 结论 补体C3对早期预测F-ET妊娠结局有一定的临床意义,当补体C3超过1.32 g/L可能会导致自然流产率升高。

Abstract:

Objective To investigate the role of complement C3 in early predicting pregnancy outcomes of frozen-thawed embryo transfer (F-ET). Methods A total of 378 F-ET cycles were prospectively collected and divided into group A (complement C3 ≤ 1.05, 120 cycles) and group B (complement C3 > 1.05, 258 cycles) based on the best cutoff value of complement C3 for predicting F-ET pregnancy outcomes. The outcomes of the two groups were compared, and the best cutoff value of complement C3 for predicting F-ET spontaneous abortion was analyzed in group B. Results Age was a risk factor for successful F-ET pregnancy (P < 0.05), and complement C3 and embryo type were protective factors for successful F-ET pregnancy (P < 0.05). The area under the receiver-operating characteristic curve (ROC) of complement C3 for predicting F-ET pregnancy outcome was 0.702, and the best cutoff value was 1.05 g/L, with a clinical pregnancy sensitivity of 87.60% and a specificity of 52.00%. The clinical pregnancy rate and embryo implantation rate in group B were both significantly higher than those in group A (67.05% vs. 52.75%, P < 0.05). The best cutoff value of complement C3 for predicting spontaneous abortion after F-ET was 1.32 g/L, with an area under the ROC curve of 0.760, a sensitivity of 69.00%, and a specificity of 81.20%. Conclusions Complement C3 is of significance in the early prediction of F-ET pregnancy outcome. When complement C3 exceeds the level of 1.32 g/L, it may lead to an increase in the rate of spontaneous abortion.
