ABSTRACT
BACKGROUND: Malnutrition is a common finding in allogeneic hematopoietic stem cell transplantation (alloHSCT) patients, and there is some evidence that malnutrition might negatively affect the transplant outcomes. METHOD: We performed a retrospective study with 148 patients aged 18-75 years, who underwent alloHSCT between 2011 and 2017. Patients were classified according to the body mass index (BMI) and the Subjective Global Assessment (SGA). The SGA was assessed on the day of hospitalization for the transplant, and classifies patients into three groups: A (well-nourished), B (moderately malnourished) and C (severely malnourished). RESULTS: The SGA classified 49 (33%) patients as well-nourished, 54 (37%) as moderately malnourished, and 45 (30%) as severely malnourished. SGA-C was also associated with severe acute graft versus host disease (aGVHD) with a cumulative incidence (CI) of 31% vs. a CI of 14% for combined well-nourished or moderately malnourished group (SGA-A or -B, P = 0.017). In multivariate analysis, SGA-C compared to SGA-A or -B, remained as an independent risk factor for aGVHD (hazard ratio - HR 1.68, 95% confidence interval - 95% CI 1.02-2.74), and nonrelapse mortality (NRM - HR 3.63, 95% CI 1.76-7.46), worse progression free survival (HR 2.12, 95% CI 1.25-3.60), and worse overall survival (HR 3.27, 95% CI 1.90-5.64). CONCLUSION: Malnutrition increases the risk of aGVHD and NRM and has a negative impact on survival.

The Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Elderly was elaborated by nutritionists, nutrologists and hematologists physicians from 15 Brazilians reference centers in hematopoietic stem cell transplantation, in order to emphasize the importancy of nutritional status and the body composition during the treatment, as well as the main characteristics related to patient's nutritional assessment. Establishing the consensus, we intended to improve and standardize the nutritional therapy during the hematopoietic stem cell transplantation. The Consensus was approved by the Brazilian Society of Bone Marrow Transplantation.

RESUMO O Consenso Brasileiro de Nutrição em Transplante de Células-Tronco Hematopoiéticas: Idoso foi elaborado com a participação de nutricionistas, médicos nutrólogos e médicos hematologistas de 15 centros brasileiros referência em transplante de células-tronco hematopoiéticas, com o objetivo de salientar a importância do estado nutricional e da composição corporal durante o tratamento, bem como as principais características relacionadas à avaliação nutricional do paciente. As intenções, ao se estabelecer o consenso, foram aprimorar e padronizar a terapia nutricional durante o transplante de células-tronco hematopoiéticas. O consenso foi aprovado pela Sociedade Brasileira de Transplante de Médula Óssea.
