Uso de la glutamina en la nutricion parenteral total de pacientes sometidos a trasplante de médula ósea

Abstract

Glutamine is an essential amino acid for nucleotide synthesis and an important energy resource for cellular division. There is contradictory evidence about its bene-fits as part of parenteral nutrition. More than 75% of bone marrow transplant patients (BMTP) have, during their evolution, digestive tract complications limiting enteral nutrition, for this reason, sometimes total parenteral nutrition (TPN) is required. Objective: Our aim was to analyze the relation between the use of glutamine in TPN of BMTP, and the evolution of clinical acute complications as mucositis, graft versus host disease (GVHD) and infections days of stay and days of TPN. Materials and Methods: observational retrospective study. All BMTP with total parenteral nutrition during the period 2007-2013 were included. We analyzed days of stay, days of nutrition, glutamine use and acute complications. Results were analyzed in SPSS 15.0. Results: 73 BMTP were divided in two comparable groups depending on glutamine use. The mean age was 36,96 ± 12,89 years. 47,9% of patients received glutami-ne in TPN. Patients who received glutamine had a mean stay of 31,49±7,41 days with 14,11±5,87 days of TPN compared with the non-glutamine group with 32,16±7,99 and 15,50±7,71 days respectively (p=0,71 y 0,39). Mucositis lasted 12,23±5,66 days in the glutamine group, and 15,50±7,71 days in the non-glutamine group (p=0,042). Severe grades of GVHD (II,III) was observed in 20,6% of the non glutamine group compared with the 13,7% of the other group (p=0,636). In patients with glutami-ne suplementation, mucositis last 12,23±5,66 days compared with 15,50±7,71 days in the non-glutamine group (p=0,042).13,7% of all patients suffered infections while receiving TPN with glutamine compared with 16,4% in patients who did not receive glutamine (p=0,700). Conclusion: In our group, a statistically significant reduction in the duration of mucositis was observed in patients who received parenteral glutamine.
