Abstract
Los pacientes receptores de trasplante de progenitores hematopoyéticos (TPH) presentan un alto riesgo de desnutrición de origen multifactorial, siendo necesaria la nutrición parenteral (NPT) en la mayoría de los casos. Existen escasos estudios previos donde se analice el estado nutricional de estos pacientes de forma global. En este estudio se analizó la composición corporal, el gasto energético, la microbiota intestinal y el perfil de aminoácidos y de acilcarnitinas previo al TPH, durante el ingreso y post-trasplante. Objetivo: El objetivo del estudio fue analizar el estado nutricional de forma multidimensional con el fin de mejorar el soporte nutricional que precisan estos pacientes en la fase precoz post-TPH. Pacientes y Métodos: Se trata de un estudio observacional prospectivo realizado en nuestro centro entre 2016 y 2018 de pacientes receptores de TPH, tanto alogénicos como autólogos, donde se estudió la composición corporal mediante DEXA realizado antes y después del ingreso hospitalario del trasplante. Además se realizó la determinación del gasto energético en reposo (GER) mediante calorimetría indirecta, del perfil de aminoácidos y de acilcarnitinas mediante metabolómica y de la microbiota intestinal mediante un estudio genómico de las heces, todo ello realizado en 5 ocasiones durante el estudio (1 semana previo al ingreso, los días +7 y +14 tras el TPH, al alta hospitalaria y a las 3 semanas después del alta)...
Patients undergoing hematopoietic stem cell transplantation (HSCT) face a high risk of multifactorial malnutrition, often requiring parenteral nutrition (PN). Few previous studies have comprehensively analyzed the nutritional status of these patients. This study examined body composition, energy expenditure, intestinal microbiota, and amino acid and acylcarnitine profiles before, during hospitalization, and post-transplantation. Objective: The aim was to analyze the nutritional status in a multidimensional manner to enhance nutritional support for patients in the early post-HSCT phase. Patients and Methods: This prospective observational study conducted at our center from 2016 to 2018 included both allogeneic and autologous HSCT patients. Body composition was studied using DEXA before and after admission. Resting energy expenditure (REE) was determined by indirect calorimetry, amino acid and acylcarnitine profiles by metabolomics techniques and intestinal microbiota by genomic study of the stool, were assessed five times during the study (1 week before admission, days +7 and +14 post-HSCT, at discharge, and 3 weeks post-discharge)...
