上海社区糖尿病前期及糖尿病人群视网膜病变患病率及相关危险因素分析

Objective To determine the prevalence and risk factors of diabetic retinopathy (DR) in the Diabetes Mellitus (DM) and impaired glucose regulation (IGR) population in Shanghai Community. Methods DR screening after the epidemiologic study of metabolic syndrome in Huayang and Canyang Community , Shanghai was conducted among 1300 patients with DM or IGR during June 2005 and March 2006, Digital non-mydriatic fundus photography was performed for each eye in all subjects. Other factors, including diabetes related history, BMI, WHR, fasting plasma glucose, HbAlc, serum lipid and blood pressure were also assessed. 642 patients,312 males and 330 females, aged 65 ± 13, with complete data were enrolled into the analysis. Results The prevalence of DR was 19. 9% in the diabetic population, and the prevalence of mild, moderate, severe non-proliferative retinopathy and proliferative retinopathy was 12. 0%, 5. 1%, 2. 3% and 0. 5%, respectively; the prevalence of DR in IGR reached 8. 0%. Logistic regression analysis revealed that HbA1c level and diabetes duration were both independently associated with diabetic retinopathy. Conclusion The prevalence of DR was high in both DM and IGR population. Bad blood glucose control and long diabetes duration both increased occurrence of DR.

老年人群糖化血红蛋白用于诊断糖调节异常的可行性研究

目的探讨老年人群中糖化血红蛋白（HbA1c）诊断糖尿病（DM）和糖调节异常（IGR）的理想切点及可行性。方法对北京万寿路社区老年人群（≥60岁）进行横断面流行病学调查,其中1 674人无糖尿病者行口服75g葡萄糖耐量试验（OGTT）,测定空腹血糖、2h血糖及HbA1c。采用受试者工作特征曲线（ROC曲线）进行判断,以OGTT诊断DM及IGR时的HbA1c值计算最佳切点。并与美国糖尿病协会（ADA）的糖尿病HbA1c诊断标准比较。结果按照1999年WHO的DM诊断标准,本研究人群中糖耐量正常（NGT）894例,空腹血糖受损（IFG）53例,糖耐量低减（IGT）369例,合并IFG＋IGT 87例,新诊断糖尿病（NDDM）271例。采用ROC曲线判断与OGTT诊断DM状态相关的HbA1c理想切点为5.9%,敏感性和特异性分别为80.1%和73.8%,曲线下面积0.832（95%CI 0.802-0.862）;与IGR状态相关的HbA1c理想切点为5.7%,敏感性和特异性分别为64.3%,60.9%,曲线下面积0.668（95%CI 0.638-0.698）。HbA1c≥5.9%作为糖尿病诊断标准与OGTT的符合率达75%,可确诊80.1%的NDDM（217例）,但包括17.3%的NGT（155例）和41.7%的IGR（212例）。按ADA HbA1c≥6.5%的标准,NDDM中的检出率只有39.1%（106例）,而特异性高仅涉及0.9%的NGT（8例）及4.5%的IGR（23例）。结论 HbA1c≥5.9%时应进一步行OGTT以明确是否患有糖尿病,≥6.5%时诊断糖尿病的特异性达到97.8%。HbA1c不适用于筛查IGR人群。     

HbA1c与FPG联合筛查诊断糖尿病的应用价值

目的 探索糖化血红蛋白（HbA1c）与空腹血糖（FPG）联合筛查糖尿病（DM）及DM高危人群的应用价值.方法 测定沧州行政和企事业单位6 533例健康体检者的HbA1c和FPG,筛查DM患者及DM高危人群,对DM诊断有疑问者进一步作糖耐量实验（OGTT）.结果 采用ADA推荐的HbA1c≥6.5％或FPG≥7.0mmol/L为筛查DM标准,本研究人群DM筛查率为10.51％,DM高危人群为18.69％.如果用HbA1c≥6.5％单项筛查DM,漏诊率占联合检出DM人数的20.23％;用FPG≥7.0 mmol/L单项筛查DM,漏诊率为21.83％.依据联合筛查提出了适于本地筛查DM的切点：HbA1c≥6.5％与FPG≥6.0 mmol/L,HbA1c≥6.0％与FPG≥7.0mmol/L可直接诊断DM;5.5％≤HbA1c＜6.0％与FPG≥7.0 mmol/L,HbA1c＜5.5％与FPG≥7.0 mmol/L,这部分人群应重新验证或作OGTT明确诊断,高者诊断DM,低者降为高危人群,对DM高危人群也提出了筛查切点.结论 HbA1c与FPG联合检测在筛查DM中可以达到较高的灵敏度和保持较高的特异性,最大限度地提高了体检人群筛查诊断DM效率.     

2型糖尿病患者液态酶法测定糖化血清白蛋白的临床观察

糖化血清白蛋白用于诊断糖尿病及糖调节异常的价值研究

目的 探讨糖化血清白蛋白（GA）作为诊断糖尿病（DM）及糖调节异常（IGR）的可能切点值,并分析GA对于诊断DM及IGR的应用价值。方法 392例为明确DM诊断而就诊者和DM高危人群接受筛查者,年龄20～84岁,行口服葡萄糖耐量试验（OGTT）,并测定糖化血红蛋白（HbA1c）和GA,以受试者工作特征曲线(ROC)评价GA诊断DM和IGR的敏感性和特异性。结果 ①按WHO1999年DM诊断标准判断,392例就诊者中DM 131例, IGR 126例,糖耐量正常（NGT）135例,3组 GA水平呈递增趋势(P r=0.942 1,P r=0.856 6,P r=0.813 7, P AUC）为0.888（95%CI:0.855～0.920）,敏感性为71.8%,特异性为87.4%,诊断价值中等。GA诊断IGR的AUC较小（0.510）,诊断价值较低。结论 GA可作为单一方法诊断DM,其最佳切点值为16.6％,敏感性和特异性分别为71.8%和87.4%。GA可能不适合用于单独诊断IGR。     

不同糖调节受损人群的血糖波动特征

目的 研究不同糖调节受损人群的动态血糖波动特征.方法 采用动态血糖监测系统(CGMS)根据连续2次口服葡萄糖耐量试验结果,选取稳定人群中单纯空腹血糖受损(IFG)组12例,单纯餐后血糖受损(IGT)组19例,空腹血糖受损合并糖耐量低减(IFG/IGT)组11例,新诊断2型糖尿病(T2DM)组21例,正常对照(NGT)组18例,分析其各项临床指标和CGMS动态血糖数据.结果 (1)日内血糖波动:NGT、IFG、IGT、IFG/IGT至T2DM组的最大血糖波动幅度(LAGE)、平均血糖(MBG)和血糖水平标准差(SDBG)依次升高.IGT组的平均血糖波动幅度(MAGE)(3.2±1.2)mmol/L较NGT组(1.6±0.5)mmol/L高,较T2DM组(5.2±1.9)mmol/L低(P<0.05);IFG/IGT的有效血糖波动频率(FGE)(5.5±2.5)次/d较NGT组(6.1±3.4)次/d低,较T2DM组(4.8±1.8)高.糖尿病前期3组间IGT组MAGE(3.2±1.2)mmol/L最高,FGE(4.9±1.8)最低.(2)日间血糖波动:与NGT组(0.8±0.3)mmo/L相比,IGT组(1.1±0.4)mmol/L、IFG/IGT组(1.2±0.4)mmol/L和T2DM组(2.0±1.0)mmol/L的日间血糖平均绝对差依次升高(P<0.05).(3)不同糖调节受损人群血糖波动特征:IFG组空腹血糖受损程度最重,餐后高峰以IFG/IGT组为著.血糖水平曲线由低至高依次为NGT、IGT、IFG/IGT、IFG、T2DM组.(4)不同HbAlc水平的血糖波动:受试者HbAlc<7%时,空腹血糖曲线几乎重合,餐后血糖曲线略微分开;HbAlc7.0%～7.9%时,餐后高峰明显上升;HbAlc≥8%时,空腹曲线明显上移,餐后波动继续升高.结论 (1)随着糖调节受损程度的加重,日内血糖波动及日间血糖波动逐渐增加.(2)正常人血糖波动幅度小,频率高;T2DM餐后血糖波动幅度大,有效波动频率低;(3)IFG组的血糖波动特征最接近于NGT,而IGT组最接近于T2DM;(4)在糖尿病前期阶段餐后血糖受损明显早于空腹.     

不同糖耐量个体胰岛β细胞功能观察及评价

目的评价正常糖耐量（NGT）、糖调节受损（IGR）、新诊断2型糖尿病（T2DM）个体胰岛β细胞功能及其相关指标的适用性。方法178例入选者行口服和静脉葡萄糖耐量试验。检测胰岛素生成指数（ΔI30/ΔG30）、胰岛素急性分泌时相（AIR）、β细胞功能指数（HOMA β）、空腹胰岛素原（FPI）及胰岛素原／胰岛素（PI／I）比值反映胰岛素分泌功能。结果IGR组的ΔI30／ΔG30、AIR较NGT组分别下降了38％、39％,HOMA β轻度下降（19％）;T2DM组的胰岛β细胞功能降低更明显,其中AIR下降84％,ΔI30／ΔG30下降70％、HOMA β下降62％。T2DM组FPI和PI／I比值也比NGT组明显升高（24．4pmol／L±18．0pmol／L or 10．9pmol／L±6．7pmol／L;14．7％±10．5％or10．0％±6．5％,P〈0．05）。ΔI30／ΔG30和AIR相关性好（r=0．75,P〈0．001）。结论IGR患者主要表现胰岛素分泌时相缺陷和HOMA β降低,至糖尿病阶段则伴有胰岛素分泌质量下降。ΔI30／ΔG30和AIR均可准确反映IGR患者胰岛β细胞功能,而在新诊断2型糖尿病患者中AIR更适用,若应用ΔI30／ΔG30须校正胰岛素抵抗。     

上海社区糖尿病前期及糖尿病人群视网膜病变患病率及相关危险因素分析

目的 了解上海社区糖尿病前期(IGR)及糖尿病(DM)人群视网膜病变(DR)的患病率及相关危险因素.方法 于2005年6月至2006年3月对在上海市华阳及曹杨两个社区代谢综合征现况调查中获得的IGR和DM病人(共1300例)进行DR筛查,将完成调查并具有完整数据的642例病人(DM者391例,IGR者251例)纳入本次分析,其中男312例,女330例,平均年龄(65±13)岁.视网膜病变采用Canon CR-DGi免散瞳眼底照相机拍照法,并根据国际临床糖尿病视网膜病变严重程度的分级标准诊断.结果 社区DM病人DR患病率为19.9%(78例),其中轻、中、重度及增殖性DR的患病率依次为12.0%、5.1%、2.3%和0.5%;IGR人群的DR患病率为8.0%(20例).Logistic回归结果 见到糖尿病病程、糖化血红蛋白是DM病人合并DR的独立危险因素.结论 上海社区高血糖人群DR的患病率较高,IGR人群已有DR发生.病程长、血糖控制差均可增加DM病人发生DR的危险.
