Abstract:
Objective To investigate the interrelationship among urinary albumin elimination rate(UAER),serum adiponectin(ADPN)and blood glucose level in patients with type 2 diabetic nephropathy(DN). Methods A total of 89 type 2 diabetic patients and 30 healthy people as control were enrolled in the study.According to UAER,the diabetic patients were divided into three groups:normal group(35 cases,UAER＜30 mg/24 h),microalbuminura group (32 cases,UAER 30-300 mg/24 h)and macroalbuminura group(22 cases,UAER＞300 mg/24 h).Serum adiponectin was measured by ELISA.Body mass index (BMI),waist hip radio(WHR),fasting plasma glucose(FPG),2-hour plasma glucose(2hPG),glycated haemoglobin(HbAlc),blood lipid and UAER were measured routinely.Data were compared among groups. Results Serum adiponectin level was lower in diabetic patients than that in healthy control group(P＜0.05).Among diabetic patients.serum adiponectin of macroalbuminura group was significantly higher than that of normal and microalbuminura groups[(67.74±14.89)vs(39.36±13.92),(54.38±10.14)ng/L,P＜0.051.Multiple regression analysis showed 2hPG,HbAlc,BMI,disease course,UAER and DBP were closely associated with the level of serum adiponectin. Correlation analysis indicated serum adiponectin was positively correlated with age (r=0.255), disease course (r=0.405), HDL (r=0.501)and UAER (r=0.843); while negatively with HbAlc (r=-0.479), FPG (r=-0.436), 2hPG(r=-0.418),BMI (r=-0.479) and WHR (r= -0.531), all P＜0.01. Conclusions Serum adiponectin is positively correlated with UAER and negatively correlated with FPG. Blood glucose level is one of the main factors affecting serum adiponectin. Strict controlling of blood glucose level is beneficial to higher level of ADPN.
