Abstract:
Objective To study the levels and clinical significance of serum angiopoietin-like protein 8(ANGPTL8)and neopurine in children with hormone sensitive primary nephrotic syndrome(NS).Methods A total of 159 children with hormone sensitive primary NS treated in the hospital from January 2018 to January 2021 were selected as the study subjects(NS group).After 1 year of follow-up,based on whether frequent recurrence occurred,they were divided into the non frequent recurrence subgroup(n=93)and the frequent recurrence subgroup(n=66).Additionally,60 children with oblique hernia who underwent e-lective surgery in the Department of Pediatrics in the hospital were selected as the control group.Enzyme-linked immunosorbent assay(ELISA)was used to detect serum levels of ANGPTL8 and neopterin.The ser-um levels of ANGPTL8 and neopterin in each group were compared.Multivariate Logistic regression analysis was used to analyze risk factors for frequent recurrence in children with hormone sensitive primary NS.The predictive value of serum ANGPTL8 and neopterin in predicting frequent recurrence in children with hormone sensitive primary NS was analyzed by receiver operating characteristic(ROC)curve.Results The serum lev-els of ANGPTL8 and neopterin in the NS group were higher than those in the control group,and the differ-ences were statistically significant(t=20.948,44.288,P＜0.001,0.001).The serum ANGPTL8,neopterin levels,CD8+T cells,24 h urine protein quantification,and urine protein conversion time in the frequent recur-rence subgroup were significantly higher than those in the non frequent recurrence subgroup,while the blood albumin,CD4+T cells,CD4+/CD8+T cell ratios were lower than those in the non frequent recurrence sub-group,and the differences were statistically significant(all P＜0.05).The serum levels of ANGPTL8 and neopterin in NS patients were significantly positively correlated with 24 h urine protein and CD8+T cells,while they were significantly negatively correlated with serum albumin,CD4+T cells,CD4l+/CD8+(all P＜0.05).Serum ANGPTL8 and neopterin were independent risk factors for frequent recurrence in children with hormone sensitive primary NS.The area under the curve(AUC)of the combined model of serum ANGPTL8 and neopurine for predicting frequent recurrence in hormone sensitive primary NS patients was 0.852(95％CI:0.813-0.889),which was higher than 0.764(95％CI:0.722-0.812)of ANGPTL8,and 0.749(95％CI:0.711-0.790)of neopurine,and the differences were statistically significant(Z=3.623,3.987,P=0.003,＜0.001).Conclusion Elevated levels of serum ANGPTL8 and neopterin are risk factors for frequent recurrence hormone sensitive primary NS.The combination detection of serum ANGPTL8 and neopterin has high predictive value for frequent recurrence in children with hormone sensitive primary NS.
