AbstractThis cross-sectional study evaluates the associations of Pentraxin 3 (PTX3) and cardiovascular disease (CVD) in hemodialysis (HD) patients. Plasma was obtained from 98 maintenance HD patients before and after a session of HD and 50 age-matched healthy subjects. We measured plasma PTX3 levels by enzyme-linked immunosorbent assay. Our results showed that plasma PTX3 levels were significantly higher in HD patients compared with controls (1.87 vs. 1.11 ng/mL, p < 0.001), and increased acutely after a single HD session (post-HD 2.18 ng/mL vs. pre-HD 1.87 ng/mL, p < 0.001). Patients with CVD had higher plasma PTX3 levels than those without CVD (2.18 vs. 1.76 ng/mL, p < 0.05). Plasma PTX3 levels correlated positively with cardiac troponin T (ρ = 0.287, p = 0.007) and carotid artery intima-media thickness (ρ = 0.294, p = 0.043). High plasma PTX3 (>1.87 ng/mL) level was positively and independently associated with CVD (OR = 3.15, p = 0.024). Receiver operator characteristics analysis showed the correlation between PTX3 and CVD more closely than high sensitivity C-reactive protein (hs-CRP) in patients whose hs-CRP were higher than 3 mg/L. The area under the curve for PTX3 and hs-CRP was 0.655 (p = 0.047) and 0.562 (p = 0.458), respectively. Moreover, plasma PTX3 levels correlated negatively with body mass index, hemoglobin, pre-albumin, total cholesterol, triglyceride, and low-density lipoprotein. These data support the main conclusions: PTX3 levels are markedly elevated in HD patients; HD procedure itself induces PTX3 elevation; plasma PTX3 is associated with CVD in maintenance HD patients. 相似文献

Objective To explore the association of serum soluble Klotho (sKlotho) with nonfatal cardiovascular disease (CVD) and all-cause/CVD mortality in maintenance hemodialysis (MHD) patients. Methods A total of 132 MHD patients admitted during October 2011 were enrolled. Serum sKlotho was measured by ELISA. Demographic data, including age, gender and comorbid conditions, were obtained from their medical histories, and parameters including calcium, phosphorus and albumin were assessed. The occurrence time of nonfatal CVD and all-cause mortality were recorded during the 60 months follow-up. MHD patients were categorized into four groups according to the quartiles of sKlotho: group Ⅰ (sKlotho<361.34 ng/L), group Ⅱ (361.34 ng/L≤sKlotho<398.81 ng/L), group Ⅲ (398.81 ng/L≤sKlotho<445.99 ng/L) and group Ⅳ (sKlotho≥445.99 ng/L). Spearman correlation analysis and binary Logistic regression analysis were used to test the association between sKlotho and nonfatal CVD events. The impacts of sKlotho on all-cause mortality and CVD mortality were assessed by Kaplan-Meier method with log-rank test. Cox regression model was applied to evaluate the effect of sKlotho on MHD patients outcomes. Results All 132 MHD patients had sKlotho ranging from 304.02 ng/L to 550.62 ng/L. And 87 patients suffered from nonfatal CVD, with 192 episodes of nonfatal CVD during the follow-up period. The sKlotho had negative correlations with coronary artery disease (r=-0.286, P=0.001), congestive heart failure (r=-0.190, P=0.029), cerebrovascular accident (r=-0.240, P=0.006) and peripheral arterial occlusion (r=-0.243, P=0.005). The sKlotho were risk factors of coronary artery disease (OR=0.989, P=0.023) and peripheral artery occlusion (OR=0.988, P=0.046). 35 patients died in the follow-up period, including 27 death from CVD. The all-cause mortality and CVD mortality rates were significantly different among four groups (P=0.036, P=0.047). Survival rates of all-cause death and CVD death varied among four groups (χ2=8.076, P=0.044; χ2=7.866, P=0.049). Patients in group Ⅳhad higher survival rates of all-cause death and CVD death than those in group Ⅰ and group Ⅱ (all P<0.05). Multivariate Cox regression analyses revealed diabetes and age were independent risk factors for all-cause mortality and CVD mortality (all P<0.05), but sKlotho was not associated with the poor prognosis (HR=0.996, P=0.256; HR=0.996, P=0.287). Conclusions Patients with lower sKlotho have worse nonfatal CVD ratio, especially coronary artery disease and peripheral arterial occlusion. Reduced serum sKlotho is associated with all-cause and CVD mortality, but sKlotho is still not a predictive indicator of prognosis of MHD patients. 相似文献

Objective To evaluate the relationship between low vitamin D level and metabolic syndrome (MS) in maintenance hemodialysis (MHD) patients. Methods A total of 143 patients who had received MHD from Jan 2016 to Jan 2017 in the dialysis center of our hospital were enrolled. Their clinical and laboratory data were collected. The serum 25(OH)D3 levels were measured by chemiluminescence instrument. According to the levels of 25(OH)D3, patients were divided into three groups: sufficient group (>30 μg/L), insufficient group (15-30 μg/L) and deficient group (<15 μg/L) to explore how the 25(OH)D3 were associated with MS and abnormal metabolic parameters, including central obesity, raised triglycerides (TG), reduced high-density lipoprotein cholesterol (HDL-C), raised systolic blood pressure (SBP), raised diastolic blood pressure (DBP) and increased fasting blood glucose (FBG). The risk factors of MS and abnormal metabolic factors were analyzed by multivariate logistic regression model. Results Among the 143 MHD patients, the median of serum 25(OH)D3 was 24.30(12.90, 29.50) μg/L and the prevalence of MS was 45.45%(65 cases). Among 3 groups the prevalence of MS, the abdominal circumference and the serum TG showed statistical differences, and they increased with the severity of 25(OH)D3 deficiency (all P<0.05). The body mass indexes of patients in the insufficient and deficient groups were elevated compared with that in the sufficient group (all P<0.05). SBP, TG and FBG in deficient group were significantly higher but HDL-C was lower than those in the other two groups (all P<0.05). The more abnormal metabolism existed, the lower 25(OH)D3 levels patients had (H=61.316, P<0.001). Multivariate logistic regression analysis showed that in MHD patients low 25(OH)D3 negatively correlated with MS (OR=0.889, 95%CI 0.846-0.934, P<0.001) and abnormal metabolic factors central obesity (OR=0.913, 95%CI 0.874-0.953, P<0.001), raised TG (OR=0.932, 95%CI 0.894-0.971, P=0.001), reduced HDL-C (OR=0.901, 95%CI 0.845-0.959, P=0.001), raised SBP (OR=0.898, 95%CI 0.847-0.953, P<0.001) and raised FBG (OR=0.956, 95%CI 0.920-0.994, P=0.024). Conclusions The prevalence of MS is high in MHD patients and low levels of 25(OH)D3 may be an independent risk factor for MS and abnormal metabolic factors. 相似文献

ObjectiveTo 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. MethodsA 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. ResultsPatients 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. ConclusionDecreased 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. 相似文献
