Abstract:
Objective To explore the value of serum leucine-rich-alpha-2-glycoprotein-1(LRG1)and CC motif chemokine ligand 19(CCL19)detecting levels in children with henoch-schonlein purpura nephritis(HSPN)for early clinical diagnosis and prognosis.Methods A sum of 108 children with HSPN who were treated at Handan Central Hospital from May 2021 to May 2023 were selected as the study subjects,meantime,72 healthy children were as the control group.The levels of LRG1,CCL19,IgM,IgA,and IgG in serum were detected.Logistic regression method was applied to analyze the influencing factors of HSPN,receiver operating characteristic was applied to evaluate the clinical value of LRG1 and CCL19 levels for early diagnosis of HSPN in children.The differences in serum LRG1 and CCL19 levels among children with HSPN in the acute,chronic,and recovery stages were analyzed,Spearman correlation was applied to analyze and explore the correlation between serum LRG1,CCL19 levels and the duration of HSPN in children.Results The levels of LRG1(184.36±23.64 ng/L)and CCL19(463.19±89.46 ng/L)in the HSPN group were obviously higher than those in the control group(149.42±18.29 ng/L,208.83±52.97 ng/L),and the differences were significant(t=10.600,21.710,all P＜0.05).The Logistic regression results showed that LRG1[OR(95％CI):1.429(1.057～1.933)]and CCL19[OR(95％CI):1.842(1.216～2.791)]were both influencing factors for the occurrence of HSPN in children(P＜0.05).According to the analysis of receiver operating characteristic(ROC),the areas under the curve(AUC)of serum LRG1,CCL19 and their combined diagnosis of HSPN in children were 0.868,0.881 and 0.952,respectively,and their combined application in clinical diagnosis was better than that of serum LRG1 and CCL19 in their separate diagnosis(Z=3.147,3.487,all P=0.001).The levels of LRG1(203.49±24.89 ng/L,177.56±23.19 ng/L)and CCL19(591.13±98.32 ng/L,415.61±89.82 ng/L)in the serum of HSPN patients in the acute and chronic stages were obviously higher than those in the rehabilitation stage(158.53±21.96 ng/L,295.17±69.61 ng/L),and the differences were significant(t=6.917,12.101;5.320,3.102,all P＜0.05),while the levels of LRG1 and CCL19 in the serum of HSPN patients in the acute stage were obviously higher than those in the chronic stage,and the differences were significant(t=5.059,8.750,all P＜0.05).Spearman correlation analysis showed that the serum levels of LRG1 and CCL19 in children with HSPN were positively correlated with their course of disease(r=0.506,0.689,all P＜0.001).Conclusion The levels of serum LRG1 and CCL19 are elevated in HSPN children,and combined detection of serum LRG1 and CCL19 can improve the early clinical diagnostic value of HSPN and evaluate the prognosis of children with HSPN.
