Abstract

Background There is no consensus regarding the timing of dialysis therapy initiation for end-stage kidney disease (ESKD) in children. As studies investigating the association between timing of dialysis initiation and clinical outcomes are lacking, we aimed to study this relationship in a cohort of European children who started maintenance dialysis treatment. Methods We used data on 2963 children from 21 different countries included in the European Society of Pediatric Nephrology/European Renal Association-European Dialysis and Transplant Association Registry who started renal replacement therapy before 18years of age between 2000 and 2014. We compared two groups according to the estimated glomerular filtration rate (eGFR) at start: eGFR >= 8mL/min/1.73 m(2) (early starters) and eGFR >= 8mL/min/1.73 m(2) (late starters). The primary outcomes were patient survival and access to transplantation. Secondary outcomes were growth and cardiovascular risk factors. Sensitivity analyses were performed to account for selection- and lead time-bias. Results The median eGFR at the start of dialysis was 6.1 for late versus 10.5mL/min/1.73 m(2) for early starters. Early starters were older [median: 11.0, interquartile range (IQR): 5.7-14.5 versus 9.4, IQR: 2.6-14.1years]. There were no differences observed between the two groups in mortality and access to transplantation at 1, 2 and 5 years of follow-up. One-year evolution of height standard deviation scores was similar among the groups, whereas hypertension was more prevalent among late initiators. Sensitivity analyses resulted in similar findings. Conclusions We found no evidence for a clinically relevant benefit of early start of dialysis in children with ESKD. Presence of cardiovascular risk factors, such as high blood pressure, should be taken into account when deciding to initiate or postpone dialysis in children with ESKD, as this affects the survival.

Abstract

Background: Left ventricular hypertrophy (LVH) is associated with a premature death in children with chronic kidney disease (CKD). We studied its change over time, related to a successful kidney transplantation (KTx) and assessed whether clinical variables were associated with the left ventricular mass index (LVMI)., Methods: We obtained the records of all children and adolescents, who were followed-up at the tertiary nephrology centre for children at the Children's University Hospital in Kosice, Slovakia, during 2008-2014, had completed echocardiographic studies while on chronic dialysis and had undergone a successful KTx, n=25. We assessed the longitudinally recorded left ventricular mass index (LVMI) and the presence/absence of LVH, and risk factors for LVH., Results: The average prevalence of LVH was 23.5 % while on dialysis, and 29.4 % after KTx (p=0.06). Pre-post changes per patient were relatively big. Uncontrolled systolic hypertension was significantly related to LVMI (p=0.03)., Conclusion: LVH is common after paediatric KTx and the reversibility of already present LVH seems to be rather problematic. Significant changes of LVMI on the individual level suggest that modification is feasible with a thorough control of (systolic) hypertension and of the other risk factors (Tab. 3, Fig. 1, Ref. 50).
