Enteral Nutritional Therapy in Pediatric Autologous Transplantation: A Descriptive Cohort Study.

Abstract

Introduction: Pediatric hematopoietic stem cell transplantation requires individualized nutritional therapy, and the use of early enteral nutrition is beneficial. This study aims to analyze the use of enteral nutrition therapy in pediatric patients undergoing autologous transplantation. Methods: This is a descriptive cohort study conducted with data from electronic medical records of pediatric patients undergoing autologous transplantation from 2017 to 2022, using enteral nutrition. Nutritional and clinical variables and biochemical markers were assessed at four time points: day 0, day +5, day +10 and day +15. Results: The sample consisted of 50 patients. On average, the nasoenteral tube was inserted on D-4 and the enteral feeding started on D-3. On D0, most patients used a normocaloric polymeric enteral formula, but on D + 10, when diarrhea (p = 0.017) and mucositis (p < 0.001) worsened, the most commonly used enteral formula was a hypocaloric pediatric semi-elemental formula. On D + 15, 35% of patients were receiving parenteral nutrition. At discharge, the patient's nutritional status had worsened compared to admission (p < 0.001). Discussion: Early use of enteral nutrition was observed, as adopted in other transplant centers and recommended in the literature. Protocols and guidelines are needed to support enteral nutritional therapy in pediatric transplantation.
