Abstract:
Objective To investigate the relationship of homocysteine and blood glucose wavy coefficient with type 2 diabetic nephropathy.Methods Glycosylated hemoglobin A1c (HbA1c),fasting blood glucose(FBG),fasting C-peptide,homocysteine(Hcy),blood-fat and 24h urinary albumin quantitative (UAlb) of 154 patients with type 2 diabetes were determined,and the blood glucose wavy coefficient were calculated after blood glucose monitored by a continuous glucose monitoring system (CGMS).The patients were divided into two groups according to the quantity of UAlb:high UAlb group (n =81 ) and normal UAlb group( n =73 ).Then the difference were compared between two groups and multiple regression analysis was done between UAlb and a variety factors.Results The course of disease in high UAlb group were significantly longer than that in normal UAlb group ( (9.68 ± 7.31 ) years vs ( 5.44 ± 3.65 ) years,t =3.427,P ＜ 0.05 ).There were significant difference on HbA1c [ ( 9.61 ± 2.44 ) ％ vs ( 8.69 ± 2.35 ) ％,t =2.162 ],blood glucose wavy coefficient [ ( 3.06 ± 0.85 ) vs (2.58 ± 0.91 ),t =2.437],low density lipoprotein-cholesterol (LDL-C) [ (3.46 ± 0.83 )mmol/L vs ( 3.01 ± 0.84 ) mmol/L,t =2.596 ],UAlb [ ( 129.64 ± 118.5 ) mg/24 h vs ( 18.14 ± 3.54 )mg/24 h,t =6.421 ),UA ( ( 335.02 ± 90.39 ) mmol/L vs ( 287.00 ± 92.03 ) mmol/L,t =2.541 ) and Hcy [ ( 15.55 ± 4.53 ) mmol/L vs ( 13.12 ± 4.44 ) mmol/L,t =2.603 ] between the two groups ( P ＜ 0.05 or P ＜0.01 ).Pearson analysis showed that the courses of disease,LDL-C,UA,Hcy and blood glucose wavy coefficient were positively correlated with UAlb ( r =0.363,0.270,0.220,0.252,0.236 respectively ; P =0.000,0.008,0.033,0.014,0.022,respectively).And the multiple regression analysis indicated that UAlb was related with courses of disease(β =0.344,P =0.000),Hcy(β =0.244,P =0.011 ) and blood glucose wavy coefficient(β =0.229,P =0.012).Conclusion The elevation of serum Hcy and blood glucose wavy coefficient are risk factors to type 2 diabetic nephropathy.Lowering Hcy concentration and reducing the glucose variability may be a new way to prevent the occurrence of type 2 diabetic nephropathy.
