目的 探讨不同糖代谢状态糖化血红蛋白(HbA1c)与胰岛β细胞功能的关系.方法 选取2010年6月至2013年2月为评价糖耐量水平而来南京大学医学院鼓楼医院内分泌科就诊者913例,所有受试者均行75 g口服葡萄糖耐量试验(OGTT)及胰岛素释放试验,测定HbA1c,根据HbA1c水平将受试者分为HbA1c <5.7%(277例)、5.7%≤HbA1c≤6.4%(391例)及HbA1c>6.4%组(245例);根据OGTT结果分为正常糖耐量组(NGT,205例),糖调节受损组(IGR,328例)及2型糖尿病组(T2DM,380例).以1/稳态模型胰岛素抵抗指数(1/HOMA-IR)、Matsuda胰岛素敏感指数(ISIM)评价胰岛素敏感性,以处置指数DI(早时相DI30、总时相DI120)评估校正胰岛素敏感性之后的胰岛β细胞功能.多组计量资料间比较采用方差分析,分类计数资料采用卡方检验,胰岛功能相关指数在校正性别、年龄、BMI之后采用一般线性模型进行比较.结果 与HbA1c <5.7%组相比,5.7%≤HbA1c≤6.4%组的DI30、DI120、ISIM、1/HOMA-IR分别下降了39%、33%、13%、14%;HbA1c>6.4%组的DI30、DI120、ISIM、1/HOMA-IR分别下降了68%、66%、21%、32%(F=12.765 ~ 317.316,均P<0.05).在正常糖耐量阶段的人群中,5.7%≤HbA1c≤6.4%组的DI30、DI120明显低于HbA1c<5.7%组(F=4.516、4.215,P<0.05);在HbA1c< 5.7%的人群中,DI30及DI120按照NGT→ IGR→T2DM的方向下降(F =87.604、108.369,P<0.05).结论 胰岛β细胞功能的进行性衰退及胰岛素抵抗共同促进了HbA1 c的升高;HbA1c与血糖结合能够更好地反映个体胰岛功能情况.

Objective To assess the relations between glycosylated hemoglobin A1c (HbA1c) and β-cell function as measured by indices derived from oral glucose tolerance test (OGTT) in Chinese subjects.Methods A total of 913 subjects,who underwent 75 g OGTT for evaluation of glucose intolerance from June 2010 to February 2013,were included.According to OGTT,the enrolled subjects were divided into the following three groups:normal glucose tolerance (NGT,n =205),impaired glucose regulation (IGR,n =328),and type 2 diabetes mellitus (T2DM,n =380).Meanwhile,the subjects were also divided into three groups according to HbA1c levels:HbA1c < 5.7% (n =277),5.7% ≤ HbA1c ≤ 6.4% (n =391),and HbA1 c > 6.4% (n =245).Insulin sensitivity was measured by Matsuda insulin sensitivity index (ISIM) and 1/homeostasis model assessment of insulin resistance (1/HOMA-IR).β-cell function adjusted by insulin sensitivity was assessed from disposition index (DI) at early-phase DI30 and total DI120.ANOVA,Chi-Square test and general linear model were used for data analysis.Results Compared with the HbA1c < 5.7% group,the DI30,DI120,ISIM,and 1/HOMA-IR were decreased by-39%,-33%,-13%,and-14%,respectively,in the 5.7% ≤HbA1c≤6.4% group,and-68%,-66%,-21%,and-32%,respectively,in the HbA1c > 6.4% group (F =12.765-317.316,all P < 0.05).In NGT group,DI30 and DI120 decreased in subjects with elevated HbA1c; in HbA1c <5.7% group,DI30 and DI120 declined as glucose increased.Conclusions Both impairment of β-cell function and insulin sensitivity contributes to the deterioration of HbA1c in Chinese population.A combination of HbA1c and OGTT is effective in screening for subjects with β-cell dysfunction.
