Resumo
O Transplante de Células Progenitoras Hematopoiéticas (TCPH) é um método terapêutico utilizado no tratamento de diversas doenças que envolvem o tecido linfo-hematopoiético, doenças autoimunes e condições não-malignas. As evidências apontam que o reconhecimento precoce de pacientes em grupos de risco nutricional no TCPH e a elaboração de um plano terapêutico para tal tem impacto positivo na redução da mortalidade. A monitorização diária das necessidades energéticas, proteicas e de nutrientes é um dos pontos cruciais da terapia, pois o paciente que é incapaz de suprir mais do que 60% das necessidades nutricionais diárias por via oral torna-se candidato a outras modalidades de terapia (enteral ou parenteral), a depender da viabilidade do trato gastrointestinal, das contra-indicações relativas a cada método (plaquetopenia na introdução de sonda nasoenteral, por exemplo) e das complicações associadas aos procedimentos (aumento das taxas de infecção de corrente sanguínea na nutrição parenteral). Se o paciente atingir mais do que 60% das necessidades nutricionais por via oral e mantiver esse aporte por pelo menos 3 dias, o suporte por nutrição enteral ou parenteral pode ser descontinuado. A literatura científica ainda não elucidou todos os questionamentos quanto à melhor abordagem nutricional em pacientes submetidos a TCPH, podendo-se observar grande variação entre as condutas orientadas pelas diretrizes internacionais mais recentes e o que se adota como prática clínica diária, chamando atenção para a necessidade da elaboração de protocolos nutricionais que diminuam essas divergências. Objetivos: elaboração de um manual de avaliação do risco nutricional e de implementação de terapia nutricional para pacientes que serão submetidos ao Transplante de Células Progenitoras Hematopoiéticas no Hospital das Clínicas de Botucatu, facilitando a tomada de decisões de acordo com as evidências científicas mais recentes e contribuindo para minimizar as divergências de condutas através de um protocolo nutricional hospitalar. Casuística e Métodos: o manual foi elaborado por meio de uma revisão narrativa da literatura científica, utilizando-se de artigos e diretrizes relevantes contidos nas bases de dados Pubmed, Lilacs e Scielo, assim como de livros textos e de consensos desde o ano 2000 até 2017. Para a busca, os termos utilizados foram “nutrition assessment", "nutrition therapy", "nutrition risk", “undernutrition”, "malnutrition", “obesity”, "chemotherapy", “blood 8 marrow transplantation”, “haematopoietic stem cell transplantation”, “body composition”, “phase angle”. Resultados: há escassez de estudos específicos relacionados a terapia nutricional e a TCPH. A busca resultou na utilização de 20 trabalhos científicos que embasam a produção desta dissertação. Considerando a estrutura e a dinâmica do Hospital das Clínicas de Botucatu, a padronização de condutas deste Manual levou à elaboração de um protocolo em forma de fluxograma que abrange a avaliação do Risco Nutricional e de aplicação da Terapia Nutricional em pacientes submetidos ao TCPH neste serviço de saúde. Conclusão: o protocolo de avaliação de Risco e de aplicação de Terapia Nutricional, redigido em forma de fluxograma, facilita a aplicabilidade do conteúdo do Manual para os profissionais que dele se utilizarão, simplifica a classificação dos grupos de risco nutricional, disponibiliza elaboração rápida de condutas e evita divergências de prescrição quanto à melhor Terapia Nutricional em pacientes submetidos ao TCPH.
Hematopoietic Stem Cell Transplantation (HSCT) is a therapeutic method used for treatment of various diseases involving lymphohematopoietic tissue, autoimmune diseases and non-malignant conditions. Evidence indicates that the early recognition of nutritional risk in HSCT patients and the elaboration of a therapeutic plan for them has a positive impact in reducing mortality. Monitoring daily needs of energy, protein and nutrient is one of the crucial points of therapy, because individuals who are unable to supply more than 60% of the daily nutritional needs orally become candidates for other modalities of therapy (enteral or parenteral), depending on the viability of the gastrointestinal tract, contraindications for each method (thrombocytopenia in the introduction of nasoenteral probe, for example) and complications associated with procedures (increased bloodstream infection rates in parenteral nutrition) . If the patient reaches more than 60% of nutritional needs orally and maintains this intake for at least 3 days, enteral or parenteral nutrition support may be discontinued. The scientific literature has not yet elucidated all the questions regarding the best nutritional approach in patients undergoing HSCT and a great variation between the conducts guided by the most recent international guidelines and what is adopted as daily clinical practice can be observed, drawing attention to the need for nutritional protocols that could reduce these divergences. Objectives: elaboration of a manual of nutritional therapy and nutritional risk assessment for patients in the Hematopoietic Progenitor Cell Transplantation program at the Hospital das Clínicas de Botucatu, facilitating decision-making according to the latest scientific evidence and contributing to minimize differences of conduct guided by a hospital nutritional protocol. Materials and Methods: the manual is a narrative review of the scientific literature, using relevant articles and guidelines contained in the Pubmed, Lilacs and Scielo databases, as well as textbooks and consensus books from year 2000 to 2017. The terms used for the research were “nutrition assessment”, “nutrition therapy”, “nutrition risk”, “undernutrition”, “malnutrition”, “obesity”, “chemotherapy”, “blood marrow transplantation”, “haematopoietic stem cell transplantation","Body composition","phase angle". Results: there are few specific studies related to nutritional therapy and HSCT. The search resulted in the use of 20 scientific papers that support the production of this dissertation. Considering the structure and dynamics of Hospital das Clínicas de Botucatu, 10 the standardization of conducts in this Manual led to the elaboration of a protocol in the form of flowchart that includes the evaluation of Nutritional Risk and Nutritional Therapy in patients undergoing HSCT. Conclusion: the risk assessment and nutrition therapy application protocols, built in the form of a flowchart, facilitate the applicability of the manual contents, simplify the classification of nutritional risk groups, provide rapid pipeline elaboration and avoid divergences of prescription regarding the best nutritional therapy in patients undergoing HSCT.
