Kitty Jager & Anneke Kramer, Jane Tizard, Enrico Verrina, Vianda Stel and Karlijn van Stralen On behalf of he ERA-EDTA and ESPN Registry Committees ERA-EDTA Registry, Dept. Medical Informatics Academic Medical Center, Amsterdam 42 nd Annual meeting ESPN, Lyon –France September 2008 Paediatric Registry of CRI: an ESPN and ERA-EDTA common effort

Paediatric data in the ERA-EDTA Registry Adult renal registries Limited number of registries affiliated with the ERA-EDTA Registry include paediatric data High quality data BUT Simple, i.e. only little detail and lacking data specifically important for children

Paediatric data in the ERA-EDTA Registry van der Heijden et al. 2004

Kramer A et al. Characteristics and Survival of Young Adults who started Renal Replacement Therapy during Childhood. NDT in press AimTo describe patient characteristics and determine the risk factors for mortality of young adults who started RRT in childhood. MethodsYoung adults in 9 renal registries who had started RRT during childhood and turned 18 years between 1985 and th birthdayStart of RRT Young adults who started RRT during childhood Paediatric data in the ERA-EDTA Registry Kramer et al. in press

Paediatric data Young adults who started RRT during childhood Kramer A et al. Characteristics and Survival of Young Adults who started Renal Replacement Therapy during Childhood. NDT in press Results N = 1777 Young adults on RRT added 1.5% to the number of incident adult patients entering adult RRT services per year

Trend in PRD Young adults who started RRT during childhood

Treatment modality at the start of RRT Young adults who started RRT during childhood

Patient Survival and Life Expectancy by treatment modality at 18th birthday Patient survival does NOT depend on PRD or on time on RRT before 18 yrs It does depend on treatment modality at 18th birthday 38 yrs 63 yrs 80 yrs yrs Life Expectancy

Paediatric data in the ERA-EDTA Registry Work in progress 1. ‘The effect of timing of renal transplantation on survival of children starting renal replacement therapy’ Background Former studies on transplant survival only included patients who actually received a kidney transplant and therefore could only examine the survival after transplantation Aim To estimate the effect of timing of the first renal transplantation on patient survival taking into account the survival on dialysis before transplantation 2. Dialysis outcomes among pediatric patients by dialysis modality With USRDS, CORR and ANZDATA

ESRD in children and young adults The need for a common effort Rare disease (EC definition – prevalence < 500 pmp) –To perform studies of sufficient sample size a strong collaborative research network is needed To increase comparability of data and to perform collaborative studies –Selection and standardization of data collection is needed
