Correlation analysis of serum VEGF,CysC,and RBP with pathology and prognosis of chronic glomerulonephritis
Objective To investigate the correlation between serum vascular endothelial growth factor(VEGF),Cystatin C(CysC),and retinol-binding protein(RBP)levels and the pathology and prognosis of chronic glomerulonephritis(CGN).Methods A total of 102 patients with CGN diagnosed and treated between June 2020 and August 2022 were selected as study participants and assigned to the observation group,which was divided according to pathological types into the mesangial proliferative nephritis(MSPGN,n=35),mesangial capillary glomerulonephritis(MPGN,n=23),membranous nephropathy(MN,n=23),and focal segmental glomerulosclerosis(FSGS,n=17)groups.Healthy subjects(n=51)were selected as the control group.Changes in serum VEGF,CysC,and RBP levels were compared,and the correlation between VEGF,CysC,and RBP levels and pathological scores was analyzed using the Pearson method.All patients were followed up for 12 months and divided according to prognoses into a progression group(n=28)and no progression/remission group(n=74).The effects of VEGF,CysC,and RBP levels on the prognosis of patients with CGN were analyzed using Cox multifactor risk regression.The area under the curve(AUC),sensitivity,and specificity of VEGF,CysC,RBP,and the combined prognoses of patients with CGN were analyzed using a receiver operating characteristic(ROC)curve.Results The VEGF,CysC,and RBP levels were higher in the observation group than in the control group(P<0.05).The VEGF,and CysC,levels in the FSGS group were higher than those in the MSPGN,MPGN,and MN groups(P<0.05).The level of RBP in FSGS group was higher than that in MSPGN group(P<0.05).Pearson correlation analysis showed that VEGF,CysC,and RBP levels were positively correlated with the pathological scores(P<0.05).The VEGF,CysC,and RBP levels were higher in the progression group than in the no progression/remission group(P<0.05).Multivariate Cox regression analysis showed that increased VEGF,CysC,and RBP levels were risk factors for the prognosis of patients with CGN(P<0.05).The ROC curve analysis showed that the AUC values predicted by VEGF,CysC,RBP,and the combination of the three were 0.828,0.844,0.760,and 0.940,respectively(P<0.05);sensitivity was 75.00%,71.40%,57.10%,and 89.30%,respectively,and specificity was 93.20%,93.20%,95.90%,and 89.20%,respectively.Conclusion Serum VEGF,CysC,and RBP are highly expressed in patients with CGN,and high pathological scores are associated with increased levels,thus also affecting patient prognosis.
