Abstract:
Objective To investigate the association between peripheral white blood cell count including its subtypes and cardiovascular disease (CVD) incidence and one-year all-cause mortality in maintenance hemodialysis (MHD) patients.Methods A total of 371 MHD patients at Zhongshan Hospital,Fudan University between March 2009 and February,2011 were enrolled.Demographic,hematological,nutritional and inflammatory markers were obtained.All patients were followed for one year to investigate the risks for CVD event and mortality.Spearman correlation and linear regression were used to assess the relationship between white blood cell count and other laboratory parameters.Difference in categorical factors between two groups were determined with Chi-square test,Difference in continuous values between two groups were assessed with t test.Kaplan-Meier analysis and Cox proportional hazards model were applied to assess one-year mortality predictors.Results Patients with CVD event had lower lymphocyte count level (1.17±0.38 vs 1.34±0.51,P＜ 0.05) and higher monocyte count level (0.44 ± 0.15 vs 0.37 ± 0.15,P＜0.01) than those without CVD event.Cox proportional hazard regression showed that an increased lymphocyte count was associated with reduced mortality risk,95％CI:0.136-0.719,P ＜ 0.01) and that an increased monocyte count was associated with increased mortality risk,95％ CI:2.657-74.396,P＜0.01) after adjustment for hsCRP.Conclusion Decreased lymphocyte level and increased monocyte level are significantly related to CVD event and are independent predictors of increased one-year all-cause mortality risk in MHD patients.
