The level and correlation of serum and urine renal damage indexes in children with sepsis / 中国医师进修杂志

ABSTRACT

Objective To investigate the levels of serum N-acetyl-β-D-glucosidase (NAG),neutrophil gelatin-related lipid transporter protein (NGAL) and urinary kidney injury molecule-1 (KIM-1)in children with sepsis and their correlation with the condition.Methods Fifty-eight children with sepsis were selected as the observation group from January 2018 to May 2019 in Guangzhou Red Cross HoSpital,and sequential organ failure assessment (SOFA) score was conducted.According to the score results,all the patients were divided into three groupsmild,moderate and severe group.Meanwhile,58 healthy children were selected as the control group,and the serum NAG,NGAL levels and urinary KIM-1 level in the two groups were detected respectively,and the differences in various indicators among the mild,moderate and severe groups were compared.Pearson correlation analysis was used to explore the correlation between serum NAG,NGAL levels and urinary KIM-1 level and SOFA scores respectively.Results The levels of serum NAG,NGAL and urinary KIM-1 in the observation group were all significantly higher than the control group(30.53 ± 7.18) U/L vs.(12.36 ± 3.46) U/L,(78.72 ± 12.97)μg/L vs.(30.62 ± 3.24) μg/L,(60.59 ± 10.73) ng/L vs.(22.54 ± 4.25) ng/L,and there were statistical differences (P＜0.05).Serum NAG,NGAL levels and urinary KIM-1 level in the moderate group and the severe group were all higher than the mild group(31.81 ± 1.41) and (34.24 ± 1.70) U/L vs.(28.11 ± 2.36)U/L,(85.94 ± 5.45) and (94.17 ± 3.91) μg/L vs.(67.45 ± 7.58) μg/L,(67.03 ± 4.63) and (72.17 ± 3.98) ng/Lvs.(51.49 ± 7.08) ng/L,while the levels of serum NAG,NGAL and urinary KIM-1 in the severe group were all higher than those in the moderate group (P＜0.05).Pearson correlation analysis showed that the levels of serum NAG,NGAL and urinary KIM-1 levels in sepsis children were positively correlated with SOFA score (r =0.836,0.935,0.892;P＜0.01).Conclusions The levels of serum NAG,NGAL and urinary KIM-1 in children with sepsis increased significantly,and were related to the severity of the disease,which provides some reference value for the judgment of the sepsis condition.
