Abstract:

Objective To investigate the early warning value of whole blood cell derived inflammatory markers [neutrophil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR),monocyte/lymphocyte ratio(MLR),systemic immune inflammation index(SII) and systemic inflammation response index(SIRI)] for delayed graft function(DGF). Methods A total of 191 patients who received allograft renal transplantation in the First Affiliated Hospital of Army Medical University from April 2018 to September 2021 were enrolled. According to whether DGF occurred after operation,the patients were classified into DGF group(33 cases) and immediate graft function(IGF) group(158 cases). The clinical data of all the patients were collected,blood routine test was performed,and NLR,PLR,MLR,SII and SIRI were calculated. Logistic regression analysis was used to evaluate the influence factors of DGF. Receiver operating characteristic(ROC) curve was used to evaluate the effectiveness of each indicator in determining DGF in renal transplantation patients. Results There was statistical significance on cold ischemia time,hot ischemia time,white blood cell(WBC) count,the absolute value of neutrophils(NEUT#),the absolute value of lymphocytes(LYMPH#) and serum creatinine(SCr) at discharge between DGF group and IGF group(P<0.05). There was no statistical significance for the other indicators between DGF group and IGF group(P>0.05). Preoperative NLR,PLR,MLR,SII and SIRI in DGF group were higher than those in IGF group(P<0.01). The areas under curves(AUC) of preoperative NLR,PLR,MLR,SII and SIRI single and combined determinations to determine DGF in renal transplantation patients were 0.736,0.696,0.672,0.744,0.696 and 0.801,respectively. Multivariate Logistic regression analysis showed that hot ischemia time and preoperative PLR and SII were independent risk factors for DGF in renal transplantation patients [odds ratios(OR) were 1.672,1.035 and 0.994,95% confidence intervals(CI) were 1.104-2.533,1.008-1.063,0.989-1.000,respectively,P<0.05]. Conclusions Preoperative whole blood cell derived inflammatory markers have potential clinical value in determining whether DGF occurs in renal transplantation patients.
