Background/Objectives: The hepatic prognosis of long-term home total parenteral nutrition (TPN)-dependent children is poorly documented. The objective was to study outcome data in home TPN-dependent children and to describe precisely their liver biopsies in the attempt to analyze risk factors for biochemical and histological hepatic abnormalities. Subjects/Methods: Medical records of 42 children receiving home TPN for more than 2 years between January 1998 and December 2007 in a single approved home total parenteral center were reviewed. Hepatic biochemical abnormalities were analyzed. Hepatic biopsies were classified by two independent pathologists. Results: Duration of TPN was 7.9 ± 0.8 years (mean ± s.e.m.), with an average age at onset of 1.5 ± 0.5 years. A total of 24 patients (57%) developed biochemical liver abnormalities in an average of 2.9±0.4 years after starting TPN. Risk factors for biochemical abnormalities were younger age at TPN commencement, longer duration of TPN, higher rate of catheter-related infections and higher volume and energy content of TPN. Liver biopsies were carried out in 43% of patients (mean age 3.2±0.9 years). Almost all patients had fibrosis (94%). Risk factors were dependent on each histological abnormality: fibrosis was significantly associated with a shorter length of bowel and a longer duration of TPN; cholestasis correlated with a lower percentage of total parenteral energy intake due to lipids; and steatosis had no risk factor identified. Conclusion: Our study reports a high rate of histological liver abnormalities and analyzes risk factors in children who underwent very long-term home TPN.

Background: The ability of growth hormone (GH) to promote the weaning-off of parenteral nutrition (PN) in short bowel syndrome (SBS) is unclear. No randomized controlled study is available in children. This study was undertaken to determine if GH could enhance the weaning off of PN in PN-dependent children with SBS. Methods: A prospective randomized open-label multicenter study was performed in 14 patients (mean age, 9 ± 1.4 years) with SBS (average small bowel length, 33 cm) and long-term PN dependency (8 years) on an unrestricted diet. A standardized PN decrease with and without GH (0.14 mg/kg/d) was conducted. The patients were randomized to either a GH group (4 months of GH) or a control (CTR) group (4 months without GH, followed by 4 months with GH). Blood tests and a nutrition assessment of enteral and parenteral intakes were performed. Groups were compared with the Wilcoxon test. Results: Treatment with GH did not improve the weaning off of PN (decrease in PN caloric intake of 32.5% ± 9.6% in the GH group vs 35.2% ± 8.7% in the CTR group, nonsignificant). In the CTR group, GH treatment induced an additional but not statistically significant decrease of 8.8% ± 12.4% in daily calories. Parenteral needs returned to near basal rates 6 months after GH discontinuation (GH: 77.6% ± 10.6% vs CTR: 73.2% ± 7.4%). Weight decreased slightly in both groups. No biological parameters varied significantly. Conclusions: GH did not improve the weaning off of PN in PN-dependent children with SBS. (JPEN J Parenter Enteral Nutr. 2011;35:723-731)
