摘要:

目的 探讨孕中期血清纤维连接蛋白(Fn)水平对妊娠糖尿病(GDM)患者并发子痫前期(PE)疾病的预测价值。方法 通过前瞻性病例对照研究,留取458例GDM孕妇在孕24~28周的血清样本,观察其妊娠状态,有30例发展为PE(PE-GDM组),有10例只被诊断为妊娠高血压(GH)(GH-GDM组);从458例观察对象中选取足月顺产且无并发症的GDM孕妇40例作为对照(GDM组)。应用免疫透射比浊法检测3个组血清中Fn水平以及相关临床生化指标水平。结果 PE-GDM组Fn中位数水平为221.72(202.33,264.52)mg/L,与GH-GDM组[185.13(174.30,216.21)mg/L]和GDM组[198.77(185.65,208.37)mg/L]相比显著增高,差异有统计学意义(P<0.05);GH-GDM组和GDM组Fn水平比较差异无统计学意义(P>0.05)。PE-GDM组三酰甘油(TG)和孕前体质量指数(BMI)中位数或均值水平分别为3.60(2.96,4.62)mmol/L和(25.10±3.20)kg/m2,2项指标均显著高于GH-GDM组[TG为2.32(2.00,2.81)mmol/L,孕前BMI为(23.97±3.36)kg/m2]和对照组[TG为2.52(2.13,2.94)mmol/L,孕前BMI为(23.38±3.61)kg/m2],差异有统计学意义(P<0.05)。受试者工作特征(ROC)曲线分析结果显示,Fn、TG、孕前BMI ROC曲线的曲线下面积(AUC)分别为0.778、0.794、0.654,95%可信区间(CI)分别为0.665~0.890、0.681~0.907、0.526~0.782;3项指标联合分析AUC为0.818,95%CI为0.714~0.921。结论 孕中期血清Fn水平对GDM患者合并PE有一定的预测价值。孕中期Fn、TG、孕前BMI 3项指标联合应用对预测GDM患者合并PE的意义更大。

Abstract:

Objective To investigate the predictive role of serum fibronectin(Fn) level in the second trimester of pregnancy for patients with gestational diabetes mellitus(GDM) complicated with preeclampsia(PE). Methods A prospective case-control study was conducted to select 458 serum samples from pregnant women with GDM from 24 to 28 weeks of gestational weeks to observe their pregnancy outcomes. Totally,30 patients developed PE as PE-GDM group,10 patients were diagnosed as gestational hypertension(GH) as GH-GDM group,and 40 cases of GDM with full-term normal delivery and no complication were enrolled from 458 subjects(GDM group). Immunofluorescence assay was used to determine the levels of Fn and related clinical biochemical indicators in the 3 groups. Results The level of Fn in PE-GDM group was 221.72(202.33,264.52)mg/L,those in GH-GDM group and GDM group were 185.13(174.30,216.21)mg/L and 198.77(185.65,208.37)mg/L,respectively(P<0.05). There was no statistical significance in Fn levels between GH-GDM group and GDM group(P>0.05). The levels of triglyceride(TG) and pre-pregnancy body mass index(BMI) in PE-GDM group were 3.60(2.96,4.62)mmol/L and (25.10±3.20)kg/m2,respectively,and they were higher than those in GH-GDM group [2.32 (2.00,2.81)mmol/L and (23.97±3.36)kg/m2] and GDM group [2.52 (2.13,2.94)mmol/L and (23.38±3.61)kg/m2](P<0.05). Receiver operating characteristic(ROC) curve analysis showed that the areas under curves(AUC) of Fn,TG and pre-pregnancy BMI were 0.778,0.794 and 0.654,respectively,and the 95% confidence intervals(CI) were 0.665-0.890,0.681-0.907 and 0.526-0.782,respectively. The AUC of the combined determination of the 3 indicators was 0.818,and the 95% CI was 0.714-0.921. Conclusions Serum Fn levels in the second trimester have a certain predictive value for GDM patients with PE. The combined determination of Fn,TG and pre-pregnancy BMI in the second trimester of pregnancy is important in predicting GDM with PE.
