  abstract  = {Background The importance of chronic kidney disease (CKD) and anaemia has not been comprehensively studied in asymptomatic patients at risk for heart failure (HF) versus those with symptomatic HF. We analysed the prevalence, characteristics and prognostic impact of both conditions across American College of Cardiology/American Heart Association (ACC/AHA) precursor and HF stages A-D. Methods and results 2496 participants from three non-pharmacological German Competence Network HF studies were categorized by ACC/AHA stage; stage C patients were subdivided into C1 and C2 (corresponding to NYHA classes I/II and III, respectively). Overall, patient distribution was 8.1\%/35.3\%/32.9\% and 23.7\% in ACC/AHA stages A/B/C1 and C2/D, respectively. These subgroups were stratified by the absence ( - ) or presence ( +) of CKD (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73m2) and anaemia (haemoglobin in women/men < 12/ < 13 g/dL). The primary outcome was all-cause mortality at 5-year follow-up. Prevalence increased across stages A/B/C1 and C2/D (CKD: 22.3\%/23.6\%/31.6\%/54.7\%; anaemia: 3.0\%/7.9\%/21.7\%/33.2\%, respectively), with concordant decreases in median eGFR and haemoglobin (all p < 0.001). Across all stages, hazard ratios [95\% confidence intervals] for all-cause mortality were 2.1 [1.8-2.6] for CKD + , 1.7 [1.4-2.0] for anaemia, and 3.6 [2.9-4.6] for CKD + /anaemia + (all p < 0.001). Population attributable fractions (PAFs) for 5-year mortality related to CKD and/or anaemia were similar across stages A/B, C1 and C2/D (up to 33.4\%, 30.8\% and 34.7\%, respectively). Conclusions Prevalence and severity of CKD and anaemia increased across ACC/AHA stages. Both conditions were individually and additively associated with increased 5-year mortality risk, with similar PAFs in asymptomatic patients and those with symptomatic HF.},

  abstract  = {Introduction Medium-cut-off (MCO) dialyzers may beneficially impact outcomes in patients on hemodialysis. Methods In a randomized, controlled trial in maintenance hemodialysis patients, the new Nipro ELISIO-17HX MCO dialyzer was compared to the Baxter Theranova 400 filter regarding middle molecule removal. Furthermore, the suitability of two assays for free lambda-light chain (λFLC) detection (Freelite vs. N-Latex) was verified. Results ELISIO-HX achieved slightly lower reduction ratios for β2-microglobulin (71.8 ± 6.0 vs. 75.3 ± 5.8\%; p = 0.001), myoglobin (54.7 ± 8.6 vs. 64.9 ± 8.7\%; p < 0.001), and kappa-FLC (62.1 ± 8.8 vs. 56.3 ± 7.7\%; p = 0.021). λFLC reduction ratios were more conclusive with the Freelite assay and not different between ELISIO-HX and Theranova (28.4 ± 3.9 vs. 38.7 ± 13.4\%; p = 0.069). The albumin loss of Theranova was considerably higher (2.14 ± 0.45 vs. 0.77 ± 0.25 g; p = 0.001) and the Global Removal ScoreLoss alb largely inferior (30.6 ± 7.4 vs. 82.4 ± 29.2\%/g; p = 0.006) to ELISIO-HX. Conclusions The new ELISIO-HX expands the choice of dialyzers for MCO hemodialysis.},
