A double-blind randomized placebo-controlled study of oral glutamine in the prevention of mucositis in children undergoing hematopoietic stem cell transplantation: a pediatric blood and marrow transplant consortium study.
Severe mucositis is a common cause of morbidity in hematopoietic stem cell transplant (HSCT) recipients. Glutamine has been shown to reduce mucositis in children receiving chemotherapy. Patients were randomized in a double-blind manner to receive glutamine or glycine at a dose of 2 g/m(2)/dose (maximum dose 4 g) twice daily until 28 days post transplant or discharge if sooner. Mucositis was graded by use of a modified Walsh scale. A total of 120 children were evaluable: 57 children received glutamine and 63 received glycine. The mean mucositis score was 3.0+/-0.3 vs 3.9+/-0.4 (P=0.07) in the glutamine and glycine groups, respectively. The glutamine group demonstrated a reduction in mean number of days of intravenous narcotics use (12.1+/-1.5 vs 19.3+/-2.8 in the glycine group, P=0.03) and total parenteral nutrition (17.3+/-1.7 vs 27.3+/-3.6 in glycine group, P=0.01). There was no statistically significant difference in toxicity between the two groups. Glutamine appears to be safe and beneficial in reducing the severity of mucositis. Strong consideration should be given to include oral glutamine supplementation as a routine part of supportive care of SCT patients.
