不同糖耐量状态孕妇血清1,5-脱水葡萄糖醇的研究

目的 通过测定不同糖耐量状态孕妇血清1,5-脱水葡萄糖醇(1,5-AG),探讨其在妊娠期糖尿病(GDM)诊断中的价值.方法 测定30例GDM孕妇(GDM组)、32例妊娠期糖耐量受损孕妇(GIGT组)及43例妊娠期糖耐量正常孕妇(GNGT组)的血清1,5-AG、空腹血糖(FPG)、1h血糖(1hPG)、糖化血红蛋白(HbA1c).结果 GDM组血清1,5-AG水平[(11.69±3.92)mg/L]显著低于GIGT组[(20.93±3.43)mg/L]和GNGT组[(27.83±4.03)mg/L](P＜ 0.01),GIGT组低于GNGT组(P＜0.05).孕妇血清1,5-AG与FPG、1hPG、HbA1c均呈显著负相关(P＜0.01).结论 孕妇血清1,5-AG与糖耐量下降相关,1,5-AG可作为GDM的诊断指标.

Serum 1,5-anhydroglucitol in pregnant women with different glucose tolerance status

Objective To explore the diagnosing value of serum 1,5-anhydroglucitol(1,5-AG)for gestational diabetes mellitus(GDM)by determining 1,5-AG in pregnant women with different glucose tolerance status.Methods The levels of serum 1,5-AG,fasting plasma glucose(FPG),1 hour plasma glucose(1hPG)and glycosylated hemoglobin(HbA1c)were determined in 30 cases GDM(GDM group),32 cases gestational impair glucose tolerance(GIGT group)and 43 cases gestational normal glucose tolerance (GNGT group).Results The level of serum 1,5-AG in GDM group[(11.69 ± 3.92)mg/L]was obviously lower than that in GIGT group[(20.93 ± 3.43)mg/L]and GNGT group[(27.83 ± 4.03)mg/L](P ＜ 0.01),GIGT group was obviously lower than that in GNGT group(P ＜0.05).The level of serum 1,5-AG had significantly negative correlation with FPG,1hPG and HbA1c respectively(P＜ 0.01).Conclusion The level of serum 1,5-AG has significantly correlation with glucose tolerance,1,5-AG can be used as useful indicator in the diagnosis of GDM.
