ABSTRACT
Objective The aim of the present study was to assess the changes of IGF-1,IGF-2,IGFBP-1 and IGFBP-3 in diabetes nephropathy,the relationships between IGFs,IGFBPs and ?_1-,?_2- microglobulin.Methods A total of 130 type-2 diabetic participants(male52,female78)aged 37~75 yeares in Guangdong Provincial People's Hospital were enrolled from Feb.2000 to May 2003.Serum IGF-1,IGF-2,IGF binding protein 1(IGFBP-1),IGFBP-3,creatinine(Cr),cholesterol,triglycerides,HDL,LDL,apolipoprotein B100(apoB100),apoA,HbA_1c,fasting and postprandial C-peptide,serum and urine ?_1-MG and ?_2-MG were measured.Patients were divided into clinical albuminuria(DN,n=24),microalbuminuria(MA,n=40),and normal(NOR,n=66)groups according sCr and urine Alb/Cr ratio.Results In multiple linear regression analysis,determinants of S ?_1-MG were IGF-2 、TC and age(r=0.492,P=0.0001);U ?_1-MG were IGF-2、age(r=0.307,P=0.007); S ?_2-MG were IGFBP-1、HDL and age(r=0.528,P=0.0001);U ?_2-MG were IGFBP-1、CP120 and age(r=0.407,P=0.0001);s-Cr were IGFBP-1、CP0 and age(r=0.499,P=0.0001)。Serum IGF-2 and IGFBP-1 were significantly increased in DN group[IGF-2(889.48?65.94)?g/L vs (711.57?28.73)?g/L,P=0.03;IGFBP-1(94.91?17.48)?g/L vs(54.81?5.04)?g/L,P=0.009].Conclusion Serum IGFBP-1 and IGF-2 are significantly increased in type 2 diabetes with nephropathy.The disorders of IGFs and lipid metabolism may contribute to the development of diabetic nephropathy.
