Neutrophil gelatinase associated lipocalin and β2 microglobulin clinical value for the early prediction of diabetic nephropathy / 国际检验医学杂志

ABSTRACT

Objective To explore the neutral grain cell gelatinase associated lipid lipocalin(NGAL ) and β2 microglobulin (β2‐MG) predictive value of diabetic nephropathy(DN) .Methods From January 2015 to April 2016 in the hospital for 78 cases of DN patients recorded as the observation group ,and then 50 cases of healthy volunteers were choosen as the control group at the same period .NGAL ,β2‐MG ,BUN ,SCr and GFR levels were compared in the two groups .And the positive rate and correlation were ana‐lyzed .Results The levels of NGAL and β2‐MG in the observation group were(473 .21 ± 127 .09)ng/mL ,(2 .76 ± 0 .45)mg/L , which were significantly higher than that in the control group(61 .36 ± 14 .230)ng/mL ,(0 .81 ± 0 .14)mg / ,respectively .The posi‐tive rate of NGAL and β2‐MG in the observation group were 96 .15% (75/78) ,91 .03% (71/78) ,which were significantly higher than that of the control group of 2% (1/50) ,6% (3/50) .While the BUN ,SCr in observation groups were significantly higher than that in the control group ,while the level of eGFR was significantly lower than that of the control group ,the differences were statis‐tically significant(both P< 0 .05) .NGAL ,β2‐MG and BUN ,SCr showed positive correlation(R = 0 .812 ,P= 0 .000 ;R = 0 .728 ,P=0 .001 ;R = 0 .748 ,P= 0 .001 ;R = 0 .685 ,P = 0 .021 ) ,and eGFR showed a negative correlation (R = - 0 .415 ,P = 0 .000 ;R=- 0 .371 ,P= 0 .000) .Conclusion The level of NGAL and β2‐MG in DN patients is significantly increased ,NGAL ,β2‐MG levels are significantly correlated with BUN .
