Growth and maturation improvement in children on renal replacement therapy over the past 20 years

Background The attainment of normal growth and maturation remains a major challenge in the management of children and adolescents requiring renal replacement therapy (RRT). Methods We compared growth and maturation in 384 German children with RRT who were followed between 1998 and 2009 with 732 children who were enrolled in the European Dialysis and Transplant Association (EDTA) Registry from 1985 to 1988; of these children, 78 and 88 %, respectively, were transplanted.

Overall, the mean height standard deviation score (SDS) has improved over the past 20 years from −3.03 to −1.80 ( p
