Orthotopic liver transplantation reverses the adverse nutritional changes of end-stage liver disease in children

The changes in growth and body composition after orthotopic liver transplantation (OLT) were studied in 61 children [median age at OLT 3.49 y (range: 0.04 14.5 y), 26 boys and 35 girls] who had survived [is greater than or equal to] 1 y post-OLT. Height, weight, midarm circumference (MAC), triceps skinfold thickness (TSF), and subscapular skinfold thickness (SSF) were measured at OLT, 3 and 6 mo later, then annually up to 5 y. SD scores (SDS) were derived from population standards. Results are reported as mean SDS [+ or -] SEM. At OLT the children were short and malnourished (height: - 0.98 [+ or -] 0.22; weight: - 0.82 [+ or -] 0.18; MAC: - 1.77 [+ or -] 0.21; TSF: - 1.27 [+ or -] 0.17; SSF: - 1.49 [+ or -] 0.17). By 3 mo post-OLT, there was a sustained improvement in MAC (- 0.73 + 0.22), TSF (- 0.47 [+ or -] 0.18), and SSF (- 0.50 [+ or -] 0.18). Weight SDS (-0.48 [+ or -] 0.20) improved by 6 mo without significant change in height SDS. The three children with Alagille syndrome were smaller (height, weight, and MAC) than children with other diagnoses but did show catch-up growth. Fulminant hepatic failure was not associated with growth failure before or after OLT. Infants (n = 14) were smaller and more malnourished at OLT (smaller skinfold thicknesses and lower weight SDS) than those who received transplants at an older age. By 1 y post-OLT, the only persisting difference was in TSF. Abnormal liver function at I y post-OLT (n = 8) and repeated episodes of steroid-treated rejection (n = 13) were associated with worsening height and weight SDS. The use of tacrolimus for graft salvage from rejection (n = 6) was not associated with growth failure. In conclusion, end-stage liver disease has a more adverse effect on MAC, TSF, and SSF than on height and weight, but a marked and rapid improvement occurred post-OLT. Children who were most severely malnourished and growth restricted at the time of OLT showed the greatest catch-up growth after OLT.
