[Parenteral nutrition in hematopoietic stem cell transplantation].

Haematopoietic stem cell transplantation (HSCT) is a sophisticated procedure used in the treatment of solid tumors, haematological diseases and autoimmune disorders, which were characterized by an extremely poor prognosis only a few years earlier. Thousands of patients receive high-dose chemotherapy and radiotherapy around the world every year in order to treat these diseases. Therapy can induce aggressive changes associated with multiple organ failure, which is usually reversible, that can lead to special nutritional and metabolic conditions. Artificial nutrition, total parenteral nutrition in particular, is provided to patients undergoing HSCT to help minimize nutritional consequences of both conditioning regimens (mucositis, malabsorption, etc.) as well as complications resulting from the procedure (graft versus host disease, venoocclusive disease of the liver). This study reviews published guidelines for the use of parenteral nutrition in HSCT and includes important aspects for nutritional support in children, including controversy on potential benefits of special nutrients (glutamine, antioxidants, etc.) and furthermore discusses future trends. This paper also addresses the pharmacists role and the necessity for multidisciplinary teams to develop specific protocols.
