Description of intervention(s) / exposure
In this observational study, consecutive critically ill children (n = 149) admitted to the PICU of a tertiary university hospital as well as a reference group of healthy children (n=60) were included. Plasma glutamine concentration and the pediatric logistic organ dysfunction score (PELOD) were determined at admission and at day 5 for patients still in the PICU.

Outcomes
Primary outcome [1] 290920 0
To evaluate if low plasma glutamine concentration is associated with the development of multiple organ failure, using the pediatric logistic organ dysfunction score (PELOD) as a multiple organ failure score and as a surrogate marker of mortality.
Timepoint [1] 290920 0
At admission.
Secondary outcome [1] 305600 0
To longitudinally investigate the development of plasma glutamine levels in critically ill patients and relate this to changes in organ failure, using the pediatric logistic organ dysfunction score (PELOD) as a multiple organ failure score and as a surrogate marker of mortality..
Timepoint [1] 305600 0
For this, the patients still in the ICU at day 5 were sampled again.

Statistical methods / analysis
Normality was assessed using the Kolmogorov-Smirnov test. Data normally distributed are given as means and S.D. Nonparametric data values are given as median (IQR). Student´s t-test, Wilson matched pair test, ANOVA followed by Tukey post-hoc test, Fisher`s exact test and Pearson´s linear regression analysis were used when applicable. (Statistica Statsoft, Tulsa, Okla, USA).
Estimation of patients needed to achieve the objectives of the study: plasma glutamine concentration as a marker of morbidity in PICU patients has not been investigated before. The variability is not known. However, in a study investigating adult ICU patients (n=80) a reduction by 50 % in mortality has been shown if the concentration of plasma glutamine is > 430 micromol/L. In the present study, one objective is to longitudinally investigate patients who stay > 5 days in the PICU. In Scandinavian PICU:s it is known that approximately 30 % of the patients will have a PICU-stay > 5 days. Therefore, the aim is to include 150 patients which will result in approximately 45 patients staying > 5 days in the PICU which would be sufficient to discover a difference in mortalty.
