Abstract

Abstract: Introduction: Patients with chronic kidney disease, especially those with end‐stage renal disease, have an increased risk of death. Previous studies have suggested neutrophil/lymphocyte ratio (NLR) was related to worse outcome in patients undergoing hemodialysis (HD). However, monocyte/lymphocyte ratio (MLR) has not been evaluated in HD patients. In this study, we prospectively studied the predictive value of MLR for all‐cause and cardiovascular mortality in HD patients and compared it with NLR. Methods: Patients who had been on a HD treatment for at least 6 months were enrolled. MLR was calculated by dividing the monocyte count by the lymphocyte count. Survival outcomes were estimated using the Kaplan‐Meier method and compared by the log‐rank test. Univariate and multivariate analyses were performed to evaluate the prognostic impact of MLR and other clinical factors on all‐cause and cardiovascular mortality. Results: Mortality rates for the lowest, middle, and highest MLR tertile group were 3.65, 7.02, and 11.15, respectively per 100 patient‐years. The Kaplan‐Meier analysis revealed that survival rates were significantly different among three MLR groups (P < 0.001). In multivariate Cox regression analyses, MLR was independently associated with all‐cause mortality (HR 4.842; 95% CI, 2.091–11.214; P < 0.001) and cardiovascular mortality (HR 6.985, 95% CI 1.943–25.115, P = 0.003) as continuous variables. NLR was not an independent predictor of all‐cause nor cardiovascular mortality after adjusted with MLR. Conclusions: The main finding of the study suggest that higher MLR was a strong and independent predictor of all‐cause and cardiovascular mortality and overwhelmed NLR among HD patients.
