Poor Prognostic Factors in Patients with Parenteral Nutrition-Dependent Pediatric Intestinal Failure

Purpose: Parenteral nutrition (PN) not only provides nutritional support but also plays a crucial role in the treatment of children with intestinal failure. The aim of this study was to evaluate the clinical significance and clinical outcomes of long-term PN.Methods: Retrospective cohort study was conducted using the medical records of patients treated at Seoul National University Children’s Hospital. This study included 19 patients who received PN for over six months. Most patients received home PN.Results: The indications for PN included short bowel syndrome, chronic intestinal pseudo-obstruction, and intract-able diarrhea of infancy. The median age of PN initiation was 1.3 years, and the median treatment duration was 2.9 years. Two patients were weaned from PN; 14 continued to receive PN with enteral feedings; and 3 patients died. The overall survival rates at 2 and 5 years were 93.3% and 84.0%, respectively. The incidence of catheter-re-lated bloodstream infections was 2.7/1,000 catheter-days and was associated with younger age at PN initiation and lower initial height Z-score. Six patients developed catheter-related central vein thrombosis, with an incidence of 0.25/1,000 catheter-days. Eleven patients experienced PN-associated liver disease (PNALD), and one patient un-derwent multi-visceral transplant. The patients with PNALD exhibited lower final heights and body weight Z-scores. All patients experienced micronutrient deficiencies transiently while receiving PN.Conclusion: PN is an important and safe treatment for pediatric intestinal failure. PNALD was linked to final anthro-pometric poor outcomes. Micronutrient deficiencies were common. Anthropometric measurements and micro-nutrient levels must be monitored for successful PN completion.Purpose: Parenteral nutrition (PN) not only provides nutritional support but also plays a crucial role in the treatment of children with intestinal failure.
