RESUMO

Objective To analyze the incidence and risk factors of microalbuminuria in newly diagnosed and hospitalized type 2 diabetes mellitus patients,and to provide the theoretical basis for therapy of diabetes and diabetic chronic complications.Methods The blood glucose,lipid profile,24h-urinaryalbumin,fasting and postprandial serum insulin and peptid C were measured in 286 newly diagnosed and hospitalized type 2 diabetic patients from Mar.2006 to Sep.2009.Microalbuminuria was defined as the 24h-urinary albumin between 30 to 300 mg twice.Insulin resistance index (HOMA-IR) was recorded and all the patients received fundus examination by ophthalmologists after expansion of the pupil to ensure whether there was retinopathy or not.Results (1)The incidence rate of microalbuminuria in this study was 19.58% (56/286).(2)Normal albuminuria group and MA group combined DR were 19.57% (45/230) and 33.93 % ( 19/56 ) respectively,and the difference was statistically significant( x2 =5.349,P =0.021 ).Compared with control,the FPG,HbA1c and HOMA-IR were significantly higher in microalbuminuria group ( FPG:[ 11.08 ± 1.76 ] mmol/L vs [9.24 ±1.65]mmol/L,t =-6.148,P <0.001;HbA1c:[11.54 ± 1.59]% vs [9.39 ± 1.64]%,t =-7.533,P <0.001 ;HOMA-IR:[3.73 ±0.42] vs [3.50 ±0.30],t =-3.774,P <0.001 ).(3) Pearson correlation analysis revealed microalbuminuria was positively correlated with FPG( r =0.460),HbA1 c ( r =0.499),HOMA-IR( r =0.308)and combined DR(r =0.405)(P <0.01).(4)Stepwise multiple regression analysis revealed that FPG (ββ =- 0.804,P < 0.01 ),HbA1 c (β =- 0.455,P < 0.01 ) and combined DR (β =1.527,P < 0.05 ) were independently risk factors of microalbuminuria.Conclusion The development of microalbuminuria in newly diagnosed and hospitalized type 2 diabetic patients is associated with FPG,HbA1c and HOMA-IR,and will be easier to merge diabetic retinopathy.
