Prevalence of liver complications in pediatric patients on home parenteral nutrition: Indications for intestinal or combined liver-intestinal transplantation

Parenteral nutrition (PN) is the only treatment for patients affected by chronic intestinal failure (CIF). Home parenteral nutrition (HPN) programs are started when patients need prolonged PN. Unfortunately, many patients on prolonged PN develop liver disease (LD). The aim of our study was to assess the prevalence of LD in our series of patients on HPN. We reviewed our records of patients discharged from the hospital on HPN for CIF. HPN was started when one parent was fully trained in the use of this treatment and if the social and familial home environment was reliable. All patients received total PN by a central venous catheter. All patients with abnormal AST, ALT, ALK, γGT, and bilirubin values for more than 3 months were considered affected by PN-related LD. Thirty-six patients (23 of whom were boys and 13 girls) were discharged on HPN. During the study period, for CIF, 16 were affected by short bowel syndrome (SBS), of whom 6 had ultra-short bowel; 16 with functional intestinal failure, and 4 with chronic intestinal pseudobstruction (CIPO). Mean duration of HPN was 2.1 years/patient. Nine of 36 patients (25%) on HPN for CIF showed LD. Seven of the 16 patients (43%) with LD were affected by SBS and 2 (12.5%) patients by functional intestinal failure. No patients with CIPO developed LD. In patients affected by SBS, the onset of LD was very earlier than in patients with ID.
