Abstract:
Objective To determine the diagnosis value of urinary albumin(mAlb)/creatinine(Ucre) ratio in random urine from patients with early diabetic nephropathy.Methods From March 2015 to December 2016,98 case with simple diabetes and early diabetic nephropathy in Ankang Hospital of Traditional Chinese Medicine were selected,including 47 cases with simple diabetes and 51 cases with early diabetic nephropathy.And 60 healthy people were selected as control group.The mAlb and mAlb/Ucre ratios in morning urine,postprandial urine and random urine were detected for three times in three days,and the resluts were calculated and analyzed.Results In early diabetic nephropathy group,the mAlb concentration varied during different time periods,mAlb in morning urine [(60.5 ± 27.1)mg/L] and postprandial urine [(60.7 ± 26.7)mg/L] were significantly increased compared with that in random urine [(40.9 ± 25.1) mg/L] (F =9.551,P =0.000).The MAlb/Ucre ratios were stable in morning urine,postprandial urine and random urine of each period (P ＞ 0.05).The positive rate of mAlb/Ucre ratio was sharply higher than mAlb alone in random urine (90.2％ vs.62.7％).No statistically significant difference showed in positive rates of mAlb/Ucre ratio in subjects from different groups(the positive rate of morning urine specimen was 92.2％;postprandial urine 88.2％;random urine 90.2％,P ＞ 0.05).Conclusion Positive rate of mAlb/Ucre ratio changed slightly during different test periods,and is superior to mAlb alone in clinic application.Additionally,the positive rate of mAlb/Ucre ratio in random urine could serve as an indicator in early screening of early diabetic nephropathy.
