Growth failure in children with end-stage renal disease remains a difficult problem. A 2.5-month-old baby in renal failure due to primary hyperoxaluria type I received intensive dialysis aimed at decreasing oxalate tissue accretion. Over 5.5 months, while awaiting transplantation, his growth velocity was 29 cm/year compared with an average 4 cm/year in infants on hemodialysis and 22 cm/year in normal infants of this age. This remarkable growth rate, which could have represented catch-up growth, is hypothesized to be related to the delivered dialysis dose. It is suggested that this relationship be evaluated in a prospective randomized trial.
