血清可溶性CD40配体对妊娠糖尿病的诊断价值

Diagnostic value of serum soluble CD40 ligand in gestational diabetes mellitus

目的探讨血清可溶性CD40配体(soluble CD40 ligand,sCD40L)对妊娠糖尿病(gestational diabetes mellitus,GDM)及妊娠不良结局的评估价值。方法选取2023年1月至12月于中山火炬开发区人民医院规律产检并分娩的100例GDM孕妇纳入GDM组,另选取同期在本院规律产检并分娩的血糖正常孕妇50名纳入正常对照组,收集两组孕妇的临床资料并随访妊娠结局。采用受试者操作特征曲线(receiver operating characteristic curve,ROC曲线)评估sCD40L对GDM的诊断价值,采用多因素Logistic回归模型探讨发生GDM的危险因素。结果孕期不同时间点,GDM组孕妇的血清sCD40L水平均显著高于正常对照组(P<0.05)。ROC曲线显示,孕早期、孕中期血清sCD40L水平辅助诊断GDM的最佳截断值分别为0.975ng/ml、1.195ng/ml,曲线下面积分别为0.812、0.878,敏感度分别为73.08%、78.43%,特异性分别为78.05%、80.00%。多因素Logistic回归分析显示年龄30~39岁、有糖尿病家族史、孕早期空腹血糖较高、孕早期sCD40L较高、孕中期sCD40L较高均是发生GDM的独立危险因素(P<0.05)。不良妊娠结局GDM孕妇的孕早期、孕中期、孕晚期血清sCD40L水平均显著高于正常妊娠结局GDM孕妇(P<0.05)。结论血清sCD40L水平在GDM及不良妊娠结局孕妇中异常增高,孕早期、孕中期血清sCD40L水平可能对GDM具有早期预警价值。

Objective To investigate the value of serum soluble CD40 ligand(sCD40L)for gestational diabetes mellitus(GDM)and adverse pregnancy outcomes.Methods A total of 100 pregnant women with GDM who received regular prenatal check-up and delivered in Zhongshan Torch Development Zone People’s Hospital from January to December 2023 were included in GDM group,and 50 pregnant women with normal blood glucose levels who received regular prenatal check-up and delivered in the hospital during the same period were included in normal control group.Clinical data of two groups were collected and pregnancy outcomes were followed up.Receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of sCD40L in GDM,and multifactor Logistic regression model was used to explore the risk factors of GDM.Results Serum sCD40L levels in GDM group were significantly higher than those in normal control group at different time points during pregnancy(P<0.05).ROC curve showed that the best cutoff values of serum sCD40L level in the first and second trimesters in assisting the diagnosis of GDM were 0.975ng/ml and 1.195ng/ml,the area under the curve was 0.812 and 0.878,and the sensitivity was 73.08%and 78.43%,the specificity was 78.05%and 80.00%,respectively.Multivariate Logistic regression showed that age 30-39 years old,family history of diabetes mellitus,higher fasting blood glucose in first trimester,higher sCD40L in first trimester and second trimester were all independent risk factors for GDM(P<0.05).The levels of serum sCD40L in the first,second and third trimesters of GDM women with adverse pregnancy outcome were significantly higher than those in GDM women with normal pregnancy outcome(P<0.05).Conclusion Serum sCD40L levels are abnormally increased in pregnant women with GDM and adverse pregnancy outcomes,and serum sCD40L levels in first and second trimesters may have early warning value for GDM.
