摘要:

目的 探讨血清淀粉样蛋白A(SAA)、同型半胱氨酸(Hcy)对妊娠期糖尿病(GDM)患者不良妊娠结局的预测作用。方法 选取2022年1月—2023年1月安吉县妇幼保健院GDM孕妇80例(GDM组)、糖耐量正常孕妇80例(对照组)。收集所有孕妇的一般资料,并检测所有孕妇孕24~28周的糖化血红蛋白(HbA1c)、血糖、血脂和SAA、Hcy水平,同时检测GDM孕妇血清一氧化氮(NO)、内皮素-1(ET-1)、白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)水平。对所有孕妇随访至妊娠结局。采用Logistic回归分析评价GDM孕妇不良妊娠结局的影响因素。采用受试者工作特征(ROC)曲线评价各项指标判断GDM孕妇不良妊娠结局的效能。结果 GDM组饮酒史、经产妇、糖尿病家族遗传史所占比例和HbA1c、空腹血糖(FBG)、餐后1 h血糖(1 h PG)、餐后2 h血糖(2 h PG)、SAA、Hcy水平均显著高于对照组(P<0.05);2个组年龄、孕周、孕前体重指数(BMI)、血压、血脂指标差异均无统计学意义(P>0.05)。GDM组不良妊娠结局发生率(23.75%)高于对照组(11.25%)(P=0.038)。GDM孕妇中不良妊娠结局发生组经产妇所占比例和SAA、Hcy、NO、ET-1、IL-6、TNF-α水平均显著高于未发生组(P<0.05)。2个组之间年龄、孕周和孕前BMI差异均无统计学意义(P>0.05)。Hcy、SAA水平升高均是GDM孕妇不良妊娠结局的危险因素[比值比(OR)值分别为1.735、1.233,95%可信区间(CI)分别为1.223~2.462、0.972~1.565,P<0.05]。Hcy、SAA、NO、ET-1、IL-6、TNF-α单项检测和SAA+Hcy联合检测判断GDM孕妇不良妊娠结局的曲线下面积(AUC)分别为0.812、0.746、0.719、0.706、0.746、0.765、0.840。结论 GDM患者SAA、Hcy水平异常升高,二者联合检测预测不良妊娠结局有一定的价值。

Abstract:

Objective To investigate the predictive role of serum amyloid A(SAA) and homocysteine(Hcy) in adverse pregnancy outcomes of patients with gestational diabetes mellitus(GDM). Methods A total of 80 GDM patients(GDM group) from Anji County Maternal and Child Health Hospital from January 2022 to January 2023 were enrolled,and 80 pregnant women with normal glucose tolerance were enrolled as control group. The general information was collected,and the levels of glycated hemoglobin A1c(HbA1c),blood glucose,blood lipid,SAA and Hcy were determined at 24-28 weeks of pregnancy. The levels of serum nitric oxide(NO),endothelin-1(ET-1),interleukin-6(IL-6) and tumor necrosis factor-alpha(TNF-α) were determined. All the subjects were followed up until the pregnancy outcome. Logistic regression analysis was used to analyze the influencing factors of adverse pregnancy outcomes in GDM patients. Receiver operating characteristic(ROC) curve was used to evaluate the efficacy of each indicator in judging the adverse pregnancy outcomes of GDM patients. Results The proportions of history of alcohol consumption,multiparity and family history of diabetes in GDM group were higher than those in control group(P<0.05),and the levels of HbA1c,fasting blood glucose(FBG),1 h postprandial blood glucose(PG),2 h PG,SAA and Hcy were higher in GDM group(P<0.05). There was no statistical significance in ages,gestational weeks,pre-pregnancy body mass index(BMI),blood pressure and bood lipid indicators between the 2 groups(P>0.05). The incidence of adverse pregnancy outcomes in GDM group(23.75%) was higher than that in control group(11.25%)(P=0.038). The proportions of multiparity and the levels of SAA,Hcy,NO,ET-1,IL-6,TNF-α in adverse pregnancy group among GDM patients were higher than those in non-adverse pregnancy group(P<0.05). There was no statistical significance in age,gestational week and pre-pregnancy BMI between the 2 groups(P>0.05). Elevated Hcy and SAA levels were risk factors for adverse pregnancy outcomes in GDM patients [odds ratios(OR) were 1.735 and 1.233,95% confidence intervals(CI) were 1.223-2.462 and 0.972-1.565,P<0.05]. The areas under curves(AUC) of Hcy,SAA,NO,ET-1,IL-6,TNF-α single determinations and SAA+Hcy combined determination in judging the adverse pregnancy outcomes of GDM patients were 0.812,0.746,0.719,0.706,0.746,0.765 and 0.840,respectively. Conclusions Elevated serum SAA and Hcy levels in GDM patients combinedly have certain clinical value in predicting adverse pregnancy outcomes.
