Elevated fibrinogen to pre‐albumin ratio predicts mortality in peritoneal dialysis patients

Abstract

AbstractbackgroundFibrinogen to pre‐albumin ratio (FPR) is a promising predictor of mortality in various cancers. The aim of this study was to explore the prognostic value of FPR to predict mortality in peritoneal dialysis (PD) patients.MethodsWe retrospectively analyzed 324 incident PD patients form January 2011 to December 2020. Patients were stratified based on the optimal thresholds for FPR at baseline to predict overall and cardiovascular mortality during follow‐up. The association of FPR and all‐cause and cardiovascular mortality was evaluated by Kaplan–Meier curve and Cox regression analysis.ResultsAll patients were divided into three groups based on the optimal cutoff value of FPR. Higher FPR levels were strongly correlated with worse overall and cardiovascular mortality in PD patients. Compared with patients in the lowest FPR tertile (<14.3), those in the highest terile (≥18.8) had multivariable‐adjusted hazard ratios (95% CI confidence interval) of 3.37 (1.76–6.49) and 2.86 (1.31–6.23) for all‐cause and cardiovascular mortality, respectively. Significant differences in overall survival were observed across nearly all subgroups after stratification.ConclusionsPatients with a high FPR had increased all‐cause and cardiovascular mortality. FPR is a potential prognostic indicator in PD patients.
