Clinical significance of glycated hemoglobin examining in patients with diabetic retinopathy ZhiYu Wang, AiYun Shi, XiaoGuang Zhang, ZhiRong Yu Department of Ophthalmology, Mindong Hospital of Ningde, Ningde 355000, Fujian Province, China Abstract AIM: To explore the clinical significance of glycated hemoglobin examining in patients with diabetic retinopathy(DR).
METHODS: One hundred and fiftyeight cases of type 2 diabetics were enrolled in this study. The concentrations of glycated hemoglobin (HbA1c) and fasting bloodglucose (FBG) were measured. And the examination of fundus and fundus fluorescence angiography were performed. Patients were divided into two groups: DR group (83 cases) and nonDR group (75 cases).
RESULTS: The concentration of HbA1c in DR group was higher than that of nonDR group (P<0.01). But the concentrations of FBG between DR group and nonDR group had no significant difference.
CONCLUSION: Glycated hemoglobin can be regarded as an important index in detection of DR and may be an effective signal for predicting DR. KEYWORDS: glycated haemoglobin; fasting blood glucose; diabetic retinopathy
方法:对本院158例2型糖尿病患者做眼底检查和荧光眼底血管造影检查,分为糖尿病正常眼底(NDR)组83例,糖尿病视网膜病变(DR)组75例,进行糖化血红蛋白(HbA1c)、空腹血糖(FBG)检测。
结果:DR组HbA1c值明显高于NDR组(P<0.01),而FBG水平在DR组与NDR组无显著性差异。
结论:HbA1c是DR的一个重要检测指标。
0引言 糖尿病视网膜病变(diabetic retinopathy, DR)是糖尿病常见的并发症和主要致盲原因之一[1]。近年来,随着糖尿病发病率的不断增加,糖尿病视网膜病变的发生率也呈上升的趋势,早发现、早治疗DR并有效监测其发展,对提高糖尿病患者的生活质量非常重要。糖化血红蛋白(glycated hemoglobin Alc,HbA1c)是反映血糖控制情况的一个敏感指标,DR的发生、发展与糖化血红蛋白密切相关[2],因此,检测HbA1c对DR的监测、治疗有着重要的意义。本研究通过对158例2型糖尿病患者进行HbA1c、空腹血糖(fasting blood glucose, FBG)的检测以了解HbA1c,FBG与DR的关系,旨在探讨糖化血红蛋白检测对糖尿病视网膜病变的临床意义,现报告如下。
1对象和方法
1.1对象 选择200606/200805本院收治的158例老年2型糖尿病患者,均符合1999年WHO制定的糖尿病诊断标准。其中男78例,女80例,年龄40~78(平均60.5)岁,糖尿病病程1~22(平均11.5)a。并发严重全身性疾病者、眼屈光介质混浊影响眼底观察者、伴有其他眼底病者予以排除。
1.2方法 DR分型、分期按现行国际临床分类法标准进行。所有病例均由眼科高年资医师专人进行散瞳眼底检查和荧光素眼底血管造影(fundus fluorecein angiography, FFA),以确定有无糖尿病视网膜病变(diabetic retinopathy, DR)并进行分组:DR组75例,其中男35例,女40例,年龄42~76(平均54.5)岁,病程5~25(平均10.5)a;糖尿病正常眼底(nondiabetic retinopathy,NDR)组83例,其中男45例,女38例,年龄40~78(平均 56.5)岁,病程6~23(平均11.0)a。各组间在性别、年龄、糖尿病病程之间无明显的差异。用金标法检测HbA1c值,用葡萄糖氧化酶法测定FBG值。 统计学分析:采用SPSS 13.0统计软件进行数据统计学处理,数据以±s表示,两组间均数比较采用t检验。
