Abstract | dc.description.abstract | Stunting is common among pediatric patients on
peritoneal dialysis. Aim: To stablish the best profile for urea kinetic variables associated to growth in
children on chronic peritoneal dialysis (PD). Patients and Methods: Twenty patients, aged 1 month
to 14 years, 13 males, were followed for 6-12 months, with monthly measurements of weight/age and
height/age Z score; plasma creatinine, BUN, protein and albumin and urine and dialysate urea
nitrogen, creatinine, protein and albumin. Minimum total Kt/V was 2.1. Dialysis dose (Kt/V), Protein
Equivalent of Urea Nitrogen Appearence (PNA), Protein Catabolic Rate (PCR) and Nitrogen Balance
(NB) were calculated. To identify the variable(s) associated to growth, the Tree Classification Model
(CART) Enterprise Miner 8.1 was applied. Results: Mean total/residual Kt/V: 3.4±1.3/1.69±1.27; Daily
Protein Intake (DPI) was 3.25±1.27 g/kg/day. nPNA, PCR and NB were 1.37±0.44, 0.84±0.33 and
1.86±1.25 g/kg/day, respectively. Mean heigth/age Z score was -2.3±1.19. Eleven patients showed a
positive height/age delta Z (mean 0.55±0.38) and nine showed a negative growth (mean -0.50±0.42).
The main variable explaining the positive growth was a Nitrogen Balance between 0.54 and 2.37 g/kg/
day, mean 1.55±0.21 (p <0.001). The second associated variable to growth was a residual Kt/V
between 0.43 and 4.6 (2.02±0.49) (p <0.05). Kt/V and nPNA showed a significant correlation, but no
correlation could be found between Kt/V and NB. Conclusions: Nitrogen Balance was the main
variable associated to growth in pediatric PD, with values between 0.53 to 2.38 g/kg/day. The second
variable was a residual Kt/V between 0.43 and 4.6. Therapy should be reassessed with NB values less
than 0.54 or above 2.37 g/kg/day (Rev Méd Chile 2005; 133: 1455-65).
