AbstractWe aimed to investigate whether annual change in the extracellular fluid to intracellular fluid (ΔECF/ICF) ratio can accurately predict mortality in hemodialysis patients. Totally, 247 hemodialysis patients were divided into two groups according to the median baseline ECF/ICF ratio of 0.563 and ΔECF/ICF ≥ 0% or < 0% during the first year, respectively. Thereafter, they were divided into four groups according to each cutoff point and were followed up for mortality assessment. The ECF/ICF ratio increased from 0.566 ± 0.177 to 0.595 ± 0.202 in the first year (P = 0.0016). During the 3.4-year median follow-up, 93 patients died (42 cardiovascular-specific causes). The baseline ECF/ICF ≥ 0.563 and ΔECF/ICF ≥ 0% were independently associated with all-cause mortality (adjusted hazard ratio [aHR] 4.55, 95% confidence interval [CI] 2.60–7.98 and aHR 8.11, 95% CI 3.47–18.96, respectively). The aHR for ECF/ICF ≥ 0.563 and ΔECF/ICF ≥ 0% vs. ECF/ICF < 0.563 and ΔECF/ICF < 0% was 73.49 (95% CI 9.45–571.69). For model discrimination, adding the ΔECF/ICF (0.859) alone and both the baseline ECF/ICF and ΔECF/ICF (0.903) to the established risk model (0.746) significantly improved the C-index. Similar results were obtained for cardiovascular mortality. In conclusion, the ΔECF/ICF ratio could not only predict all-cause and cardiovascular mortality but also improve predictability of mortality in hemodialysis patients.

Abstract Background and Aims The volume factor of maintenance hemodialysis patients is closely related to the prognosis. We hypothesized that the excess weight after dialysis (end-dialysis over-weight, edOW) is an important factor of volume impact survival in hemodialysis (HD) patients. The purpose of this study was to analyze the relationship between edOW and long-term prognosis of patients with maintenance hemodialysis. Method This retrospective study observed incident hemodialysis patients who treated in Kidney Disease Center, the First Affiliated Hospital, College of Medicine, Zhejiang University from January 1, 2008 to April 30, 2017, three times a week for at least one year. The end point of follow-up was death, abdominal dialysis, kidney transplantation, transfer or until April 30, 2018. The general data of the patients included age, gender, BMI, primary renal disease, CVD, first hemodialysis access, albumin(Alb), Haemoglobin(Hb), blood pressure, heart rate, ultrafiltration rate(UFR), interdialytic weight gain IDWG, end -dialysis overweight (edOW). Cox multivariate regression was used to analyze the relationship between edow and all-cause mortality and cardiovascular mortality. Results Totally 469 patients male, 64% were enrolled, with an average age of 56.9 ± 17.1 years. During the follow-up period, 102 patients died. The main cause of death was cardiovascular and cerebrovascular events, accounting for 44.7%. The mean value of edow was 0.28 ± 0.02 kg. Kaplan-Meier(Log-rank test) survival analysis showed that the long-term survival rate of the group with edow ≤ 0.28kg was better than that of the group with edow &gt; 0.28kg (P = 0.042), and the cardiovascular mortality of the group with edow &gt; 0.28kg was significantly higher than that of the group with edow ≤ 0.28kg (P = 0.001). Cox multivariate regression analysis showed that edow was an independent risk factor for all-cause death in hemodialysis patients (P = 0.025, AhR = 1.541, 95% CI 1.057-2.249), and also an independent risk factor for CVD death in hemodialysis patients (P = 0.007, AhR = 1.929, 95% CI 1.198-3.107). Conclusion EdOW is an independent risk factor of long-term all-cause and cardiovascular death in hemodialysis patients.

Maintenance Hemodialysis Patients

Background. Renal anemia is a common complication of hemodialysis patients. Erythropoietin (EPO) hyporesponsiveness has been recognized as an important factor to poor efficacy of recombinant human erythropoietin in the treatment of renal anemia. More importantly, increased erythropoiesis resistance index (ERI) may be associated with inflammation and increased mortality. Objective. The objective of this research was to investigate correlated factors of EPO responsiveness and to clarify the relationships between EPO hyporesponsiveness and cardiovascular mortality and all-cause mortality among maintenance hemodialysis patients. Methods. This prospective cohort study enrolled 276 maintenance hemodialysis patients for a 55-month follow-up to investigate the factors related to ERI and its relationship to all-cause mortality and cardiovascular mortality. Results. ERI was positively correlated with predialysis serum high-sensitivity C-reactive protein ( r = 0.234 , p < 0.001 ), alkaline phosphatase ( r = 0.134 , p = 0.028 ), and ferritin ( r = 0.155 , p = 0.010 ) and negatively correlated with albumin ( r = − 0.206 , p < 0.001 ) and creatinine ( r = − 0.232 , p < 0.001 ). As multiple linear regression showed, predialysis serum albumin, high-sensitivity C-reactive protein, ferritin, and creatinine were independent correlated factors of ERI ( p < 0.05 ). Kaplan–Meier curves showed that the cumulative incidences of both cardiovascular mortality and all-cause mortality were significantly higher in patients with ERI > 11.04   IU / kg / w / g / dL (both p < 0.01 ). The high ERI group was significantly associated with higher risk for all-cause mortality (OR 1.781, 95% CI 1.091 to 2.910, p = 0.021 ) and cardiovascular mortality (OR 1.972, 95% CI 1.139 to 3.417, p = 0.015 ) after adjusting for confounders. Conclusions. Predialysis serum albumin, high-sensitivity C-reactive protein, ferritin, and creatinine were independent correlated factors of EPO responsiveness among maintenance hemodialysis patients. Patients with higher ERI values had a higher all-cause mortality rate and cardiovascular mortality rate.

Maintenance Hemodialysis Patients

Background: Much controversy remains in the literature with respect to whether soluble suppression of tumorigenicity 2 (sST2) can serve to predict all-cause death in patients undergoing maintenance hemodialysis (MHD). This meta-analysis therefore sought to analyze extant datasets exploring the association between these 2 variables in MHD patients in order to draw relevant conclusions. Methods: Articles published through December 2018 in PubMed and Embase were independently reviewed by 2 authors to identify relevant articles, and STATA 12.0 was used for statistical analyses of relevant results and study parameters. Results: In total, we identified 4 relevant studies that were incorporated into this meta-analysis. These studies included a total of 1,924 participants (60% male, mean follow-up 911 days). The combined study results suggested that increased levels of sST2 were significantly linked to a 2.23 fold rise in all-cause mortality (hazard ratio [HR] 2.23, 95% CI 1.81–2.75). Subgroup analyses confirmed that this same association was true in patients undergoing hemodialysis (HR 2.17, 95% CI 1.74–2.71), which indicated that the increased levels of sST2 were significantly linked to a 2.17 fold rise in all-cause mortality. Conclusions: This analysis suggests that there is a significant link between elevated levels of sST2 and death in patients undergoing MHD. Further large-scale trials, however, will be needed to fully validate these findings and their clinical relevance.

Objectives Several studies have examined the possible association between late referral to a nephrologist and mortality on maintenance hemodialysis. However, we lack information on the benefit of early nephrologist referral in patients receiving peritoneal dialysis (PD). Patients and Methods In an inception cohort of 102 consecutive PD patients identified in a single center between 2003 and 2004, we sought to determine whether late nephrologist referral was associated with poor outcomes. The primary end point was all-cause mortality. The effects of early referral to a multidisciplinary low clearance clinic on cardiovascular mortality and length of hospitalization were also evaluated. Results Of 102 incident PD patients, 61 subjects (59.8%) were referred early to the nephrologist (more than 3 months) before dialysis initiation. During the study period of 284.9 patient-years (median follow-up period 36.8 months), 25 patients died, 12 due to cardiovascular causes. Both cardiovascular and all-cause mortality were significantly increased among PD patients with late referral, but the relationship between late referral and all-cause mortality was mitigated substantially by adjusting for relevant factors. In univariate analysis, late nephrology referral was associated with increased cardiovascular mortality, with a hazard ratio of 5.43 (95% confidence interval 1.46 – 20.21, p = 0.012). Annual adjusted days of hospitalization were similar between the early and late nephrology referral groups. Conclusions A comprehensive analysis of incident PD subjects confirmed the significant relationship between late nephrology referral and all-cause and cardiovascular mortality. A causal relationship remains to be established and validated.

<b><i>Background:</i></b> Hemodialysis patients, who are often excluded from cardiovascular (CV) clinical trials, are associated with higher CV morbidity and mortality. The risk stratification scheme for these patients is lacking. Therefore, this investigation examined the independent CV prognostic value of high-sensitive cardiac troponin T (hs-cTnT) and added prognostic value over echocardiographic parameters and other clinical risk predictors in asymptomatic stable maintenance hemodialysis (MHD) patients. <b><i>Methods:</i></b> 181 patients with end-stage renal disease undergoing MHD were eligible from the dialysis center of Tongren Hospital, Shanghai Jiao Tong University School of Medicine between October 2017 and September 2018. These patients were followed until September 2020 or until death. The median follow-up was 31 (IQR: 21–33) months. Outcome measures were all-cause mortality, first fatal or nonfatal CV events (CVEs), and 4-point composite major adverse CVEs (MACE). We performed multivariable Cox regression analysis using demographic, clinical, laboratory, and echocardiographic data to identify predictors of CV outcomes. We also evaluated the increased discriminative value associated with the addition of echocardiographic parameters and hs-cTnT using net reclassification improvement (NRI) and integrated discrimination improvement (IDI). <b><i>Results:</i></b> During follow-up, 37 patients died, 84 patients suffered one or more CVEs, and 78 patients developed 4-point MACE. In univariable analyses, age, dialysis vintage, diastolic blood pressure, parathyroid hormone concentrations, hs-cTnT, B-type natriuretic peptide, left ventricular mass index (LVMI), and <i>E</i>/<i>E</i>′ predicted all end points. hs-cTnT remained a strong predictor for each end point in multivariate analysis, whereas LVMI and <i>E</i>/<i>E</i>′ did not. The addition of hs-cTnT on top of clinical and echocardiographic variables was associated with improvements in reclassification for CVEs (NRI = 44.6% [15.9–74.3%], IDI = 15.9% [5.7–31.0%], all <i>p</i> &#x3c; 0.001), all-cause mortality (NRI = 35.5% [10.1–50.2%], <i>p</i> &#x3c; 0.001, IDI = 4.4% [1.3–8.5%], <i>p</i> = 0.005), and 4-point MACE (NRI = 47.2% [16.1–64.9%], <i>p</i> &#x3c; 0.001, IDI = 16.9% [5.5–37.3%], <i>p</i> = 0.005). Adding echocardiographic variables on top of clinical variables and hs-cTnT was not associated with significant improvements in NRI and IDI (all <i>p</i> &#x3e; 0.05). <b><i>Conclusions:</i></b> Our data suggest that hs-cTnT is a powerful independent predictor of CV outcome and all-cause mortality in stable MHD patients. The additional use of echocardiography for improvement of risk stratification is not supported by our results.

Nutritional Risk Index

Regular nutritional assessment may decrease the mortality rate in patients undergoing hemodialysis. This study aimed to evaluate whether annual change in geriatric nutritional risk index (ΔGNRI) can precisely predict mortality. We retrospectively examined 229 patients undergoing hemodialysis who measured geriatric nutritional risk index (GNRI). Patients were divided into four groups according to the baseline GNRI of 91.2, previously reported cutoff value, and declined or maintained GNRI during the first year (ΔGNRI < 0% vs. ΔGNRI ≥ 0%): Group 1 (G1), GNRI ≥ 91.2 and ΔGNRI ≥ 0%; G2, GNRI ≥ 91.2 and ΔGNRI < 0%; G3, GNRI < 91.2 and ΔGNRI ≥ 0%; and G4, GNRI < 91.2 and ΔGNRI < 0%. They were followed for mortality. During a median follow-up of 3.7 (1.9–6.9) years, 74 patients died, of which 35 had cardiovascular-specific causes. The GNRI significantly decreased from 94.8 ± 6.3 to 94.1 ± 6.7 in the first year (p = 0.035). ΔGNRI was negatively associated with baseline GNRI (ρ = −0.199, p = 0.0051). The baseline GNRI < 91.2 and ΔGNRI < 0% were independently associated with all-cause mortality (adjusted hazard ratio (aHR) 2.59, 95%, confidence interval (CI) 1.54–4.33, and aHR 2.33, 95% CI 1.32–4.32, respectively). The 10-year survival rates were 69.8%, 43.2%, 39.9%, and 19.2% in G1, G2, G3, and G4, respectively (p < 0.0001). The aHR value for G4 vs. G1 was 3.88 (95% CI 1.62–9.48). With regards to model discrimination, adding ΔGNRI to the baseline risk model including the baseline GNRI significantly improved the net reclassification improvement by 0.525 (p = 0.0005). With similar results obtained for cardiovascular mortality. We concluded that the ΔGNRI could not only predict all-cause and cardiovascular mortality but also improve predictability for mortality; therefore, GNRI might be proposed to be serially evaluated.

Abstract Background The PADIT trial identified 5 independent predictors of cardiac implantable electronic device (CIED) infection (prior procedure, age, chronic kidney disease, immunosuppression and type of procedure) and developed a novel infection risk score. Aim To assess whether the PADIT score (PS) could predict CIED reinfection and adverse events in patients (pts) submitted to transvenous lead extraction (LE) using the Pisa Technique (PT) due to CIED infection. Methods We conducted a single-centre prospective study of consecutive procedures (P) of LE using the PT between February 2013 and October 2019. Demographic, clinical, microbiological, device/ procedure related variables, morbidity and mortality data were retrieved during follow-up (FUP). An univariate analysis was performed to evaluate the ability of the PS to predict CIED reinfection (Re), procedural complications (C), all-cause hospital mortality (M), all-cause mortality/ hospitalization during first year of follow-up (MH1) and cardiovascular mortality (CM). Results A total 171 Ps including 159 pts, of which 80.7% (130 pts)were due to CIED infection: 55.1% due to pocket site infection, 18.8% to occult bacteremia with probable CIED infection and 26.1% due to both pocket site and systemic infection, with 44% of pts presenting with valvular/ lead vegetation (mean age - 70.3Y, 77.7% male, mean LVEF of 49.6%). The Rs rate was 93.1% and the clinical success rate was 99.2%. There were no deaths related to the procedure. During a mean FUP of 33 months, 11 pts had to undergo a new P, 5 of them due to pocket reinfection. The mortality rate was 24.2% (37 pts), with 8 pts dying during hospital stay, and 19 pts during the first year post-P. The mean PS was 2.9±2.5 (min- 0, max- 10). A higher PS value was associated with Re (HR - 1,43, CI95% 1.09–1.87, p=0.011), CM (HR - 1,39, CI95% 1.06–1.85, p=0.018) and MH1 (OR - 1,19, CI95% 1.03–1.38, p=0.021). There was no association between the PS and the rate of clinical success of the procedure (2.9% vs 4.5%, p=0.395), procedural complications (2.9% vs 3.3%, p=0.656) and M (4.0% vs 2.8%, p=0.192). Interestingly, a higher PS was not associated with a higher use of an antibacterial envelope during device reimplantation (3.5% vs 2.9%, p=0.371). Conclusion The PADIT score revealed a high predictive power for reinfection, all-cause mortality/ hospitalization during first year of follow-up and cardiovascular mortality in pts submitted to LE using the PT for CIED infection.

Obestatin, a proposed anorexigenic gut hormone, has been shown to have a number of beneficial cardiotropic effects in experimental studies. We hypothesized that obestatin alteration in hemodialysis patients may link to clinical outcomes. This cross-sectional study with prospective followup for almost 4 years was performed on 94 prevalent hemodialysis patients. Obestatin, leptin, proinflammatory cytokines (tumor necrosis factor-α[TNF-α], interleukin-6, and various nutritional markers were measured. Patients with low obestatin levels, defined as a level less than median, had a worse all-cause mortality and cardiovascular mortality. The crude all-cause (HR 2.23, 95% CI 1.17 to 4.24) and cardiovascular mortality hazard ratios (HR 4.03, 95% CI 1.27 to 12.76) in these patients continued to be significant after adjustment for various confounders for all-cause mortality. Across the four obestatin-TNF-αcategories, the group with low obestatin and high TNF-α(above median level) exhibited a worse outcome in both all-cause mortality and cardiovascular mortality. Clinical characteristics of patients in low obestatin high TNF-αgroup did not differ from other obestatin-TNF-αcategorized groups. In summary, low serum obestatin concentration is an independent predictor of mortality in prevalent hemodialysis patients. Novel interactions were observed between obestatin and TNF-α, which were associated with mortality risk, especially those due to cardiovascular causes.

Objectives. The association between platelet distribution width (PDW) and mortality in hemodialysis (HD) patients has received little attention. Methods. We retrospectively enrolled HD patients in a single center from January 1, 2008, to December 30, 2011. The primary and secondary endpoints were all-cause and cardiovascular mortality, respectively. The association between PDW and mortality was estimated by Cox regression model. Results. Of 496 patients, the mean age was 52.5 ± 16.6 years, and the Charlson comorbidity index was 4.39 ± 1.71. During the follow-up period of 48.8 ± 6.7 months, 145 patients (29.2%) died, including 74 (14.9%) cardiovascular deaths. 258 (52.0%) with PDW < 16.31% were in the low group and 238 (48.0%) in those with PDW ≥ 16.31% according to cut-off for all-cause mortality by receiving-operator characteristics. After adjusting for confounding factors, high PDW values were independently associated with higher risk of all-cause (hazards ratio (HR) = 1.49, 95% confidence interval (CI) 1.15–6.82) and cardiovascular deaths (HR = 2.26, 95% CI 1.44–3.63) in HD patients. When comparing with quartile 1 of PDW, quartile 4 of PDW was independently associated with a higher risk of all-cause (HR = 1.59, 95% CI 1.18–5.30) and cardiovascular deaths (HR = 2.71, 95% CI 1.49–3.76) in HD patients. Conclusions. Baseline PDW was independently associated with all-cause and cardiovascular mortality in HD patients.
