[Nutritional evolution during the early stages of hematopoietic stem cell transplantation: importance of the phase angle].
Nutrición Hospitalaria : Organo Oficial de la Sociedad Española de Nutrición Parenteral y Enteral 2023 October 28
INTRODUCTION: the aim of this study is to compare the changes in anthropometry, dynamometry and bioelectrical impedance analysis (BIA) of patients undergoing autologous and allogeneic hematopoietic stem cell transplantation (HSCT) after the conditioning period and one-week post-transplantation, and to assess whether these early changes are associated with the development of later complications.
METHODS: prospective cohort study. Nutritional status was assessed by anthropometry, dynamometry and BIA at three different defined times: T1, time of admission; T2, after the myeloablative conditioning period; and T3, day + 8 post-HSCT.
RESULTS: forty patients were evaluated, 17 received autologous HSCT (TAU) and 23 received allogeneic HSCT (TAL). Patients with TAL had higher mortality and hospital stay compared to patients with TAU. Those who developed graft versus host disease (GVHD) presented a lower phase angle (PA) than those who did not develop this complication (T2: TAL PA with GVHD 4.8° vs TAL PA without GVHD 5.5°, p = 0.007). The patients who died during the hospital stay are all from the TAL group and had PA less than 5° at T3. Weight, body mass index (BMI) and fat-free mass index (FMI) did not show a significant impact, and all of them were influenced by total body water.
CONCLUSIONS: early nutritional evaluation of these patients by phase angle seems promising, since it is not altered by water retention and can be evaluated before anthropometric changes occur.
