Abstract:
Objective To investigate the correlation between plasma pentraxin 3 (PTX3)and cardiovascular disease(CVD) in maintenance hemodialysis(MHD) patients.Methods Plasma was obtained from 98 MHD patients before and after a session of HD and 50 age-matched healthy subjects.Plasma PTX3 was measured by enzyme-linked immunosorbant assay (ELISA).Spearman correlation and linear regression were used to examine the correlation between plasma PTX3 level and other laboratory parameters.Binary Logistic regression was used to assess the correlation between plasma PTX3 level and CVD.Receiver operator characteristic (ROC) curve was used to analyze the correlation among PTX3, high sensitive C-reactive protein(hsCRP) and CVD.Results Plasma PTX3 level was significantly higher in MHD patients compared to healthy controls [1.87 (1.34-2.50) μg/L vs 1.11(0.86-1.51) μg/L, P＜0.01], and increased after a single HD session[post-HD 2.18(1.80-3.14) μg/L vs pre-HD 1.87(1.34-2.50) μg/L, P＜0.01].Patients with CVD had higher concentrations of PTX3 than those without CVD[2.18 (1.48-2.74) μg/L vs 1.76 (1.25-2.26) μg/L, P＜0.05].High plasma PTX3 (＞1.87 μg/L) was positively and independently associated with CVD[OR=3.15, 95％CI(1.17-8.50), P＜0.05].ROC curve analysis showed the PTX3 was more closely correlated to CVD than hsCRP in MHD patients with hsCRP ＞3 mg/L, and the area under the curve of PTX3 and hsCRP was 0.655 ±0.083(P＜0.05) and 0.562±0.083(P＞0.05) respectively.Plasma PTX3 level was negatively correlated with body mass index (ρ=-0.248,P＜0.05), pre-albumin(ρ=-0.218, P＜0.05), total cholesterol(ρ=-0.265, P＜0.01), triglyceride (ρ=-0.246, P＜0.05), LDL-cholesterol (ρ=-0.254, P＜0.05), hemoglobin (ρ=-0.212, P＜0.05), and positively with erythropoietin dose per week(ρ=0.184, P＜0.01), cardiac troponin T (ρ=0.287,P＜0.01), carotid artery intima-media thickness (ρ=0.294, P＜0.05).Conclusions PTX3 level ismarkedly elevated in HD patients.HD procedure induces PTX3 elevation.Plasma PTX3 could be auseful marker of CVD risk factors in MHD patients.
