The value of diabetic dermopathy screening for diabetic nephropathy / 中国医师进修杂志

ABSTRACT

Objective To explore the related risk factors for diabetic nephropathy(DN) and discuss the value of diabetic dermopathy (DD) screening for DN.Methods A total of 188 patients with type 2 diabetes mellitus (T2DM) were studied,which included 78 patients with DN (DN group) and 110 cases without DN (non-DN group).The sex,age,duration of diabetes mellitus,smoking,DD,body mass index (BMI),systolic blood pressure (SBP),diastolic blood pressure (DBP),fasting blood glucose (FBG),2hours postpradial glucose(2 h PG),triglyceride (TG),total cholesterol (TC),glycosylated hemoglobin A1c (HbA1c),fasting C-peptide(FC-P) were recorded.Multiple factor Logistic regression was applied in patients with DN and non-DN.Results The incidence of DD and DN in T2DM patients was 47.34％(89/188) and 41.49％ (78/188) respectively.The ratio of DD in DN group was 79.49％(62/78),in non-DN group was 24.55％ (27/110),and the difference was significant (P ＜ 0.05).The age,duration of diabetes mellitus,SBP,FBG,2 h PG,HbA1c in DN group was higher than that in non-DN group [(52.83 ± 6.43) years old vs.(50.35 ±6.48) years old,(10.51 ±4.36) years vs.(6.48 ±3.25) years,(137.42 ± 14.17) mmHg(1mmHg =0.133 kPa) vs.(132.57 ± 15.38) mmHg,(11.95 ±2.83) mmol/L vs.(10.28 ± 1.98) mmol/L,(15.07 ± 3.16) mmol/L vs.(13.51 ± 2.75) mmol/L,(9.62±2.17)％ vs.(8.63 ± 2.08) ％],FC-P was lower than that in non-DN group [(1.76 ± 0.89) μ g/L vs.(2.01 ± 0.72) μ g/L],and the difference was significant (P ＜ 0.05).Multiple factor Logistic regression analysis showed that duration of diabetes mellitus,DD and FPG were still related to DN in T2DM (OR =4.841,3.209,3.368,P ＜0.01).Conclusions DD is correlated with DN in T2DM.DN should be screened in T2DM patients with DD.
