ABSTRACT

INTRODUCTION: The aim of this study is to compare molecule removal and albumin leakage in postdilution online hemodiafiltration with different high-flux dialyzers. METHODS: We studied seven high-flux dialyzers (Polyflux 210H®, Evodial 2.2®, FxCordiax1000®, Elisio21H®, TS-2.1SL®, XevontaHi20®, VitaPES 210-HF®) in 6 patients. The reduction ratio (RR) of small- and middle-sized molecules was calculated. Dialysate samples were collected to estimate the albumin leakage. FINDINGS: Global differences between dialyzers were observed in the RR of ß2 microglobulin (P =0.003) and prolactin (P =0.013). The mean loss of albumin in the dialysate per session varied between 114 ± 67 mg (with Evodial 2.2) and 2621 ± 1363 mg per session (with XevontaHi20). We found global differences between dialyzers in total albumin loss (P = 0.05). DISCUSSION: We demonstrated that the performance of high-flux dialyzers was different among the types and that not all high-flux dialyzers should be considered equal.

ABSTRACT

BACKGROUND: A multidisciplinary approach and Doppler ultrasound (DU) assessment for the creation and maintenance of arteriovenous fistulas (AVF) for haemodialysis can improve prevalence and patency. The aim of this study was to analyse the impact of a new multidisciplinary vascular access (VA) clinic with routine DU. MATERIAL AND METHODS: We analysed the VA clinic results from 2014 and 2015, before and after the implementation of a multidisciplinary team protocol (vascular surgeon/nephrologist) with routine DU in preoperative mapping and prevalent AVF. RESULTS: We analysed 345 and 364 patients from 2014 and 2015 respectively. The number of surgical interventions was similar in both periods (p=.289), with a trend towards an increase in preventive surgical repair of AVF in 2015 (17 vs. 29, p=.098). 155 vs. 169 new AVF were performed in 2014 and 2015, with a significantly lower primary failure rate in 2015 (26.4 vs. 15.3%, p=.015), and a non-significant increase in radiocephalic AVF, 25.8 vs. 33.2% (n=40 vs. 56), p=.159. The concordance between the indication at the clinic and the surgery performed also increased (81.3 vs. 93.5%, p=.001). Throughout 2015 fewer complementary imaging test were requested from the clinic (78 vs. 35, p <.001), with a corresponding reduction in costs (€87,716 vs. €59,445). CONCLUSIONS: Multidisciplinary approach with routine DU can improve VA results, with a decrease in primary failure rate, higher likelihood of radiocephalic AVF, better management of dis-functioning AVF and lower radiological test costs.
