Background/Objectives:
This pilot study aimed to evaluate the metabolic profiles in plasma and cerebrospinal fluid (CSF) of 14 patients with acute lymphoblastic leukemia (ALL) and plasma of a control group, using proton magnetic resonance spectroscopy (1H NMR).
Methods:
Multivariate analysis, including orthogonal partial least-squares discriminant analysis (OPLS-DA), was used to analyze the metabolome composition.
Results:
Significant differences in plasma metabolic profiles were found between the ALL and control groups. We detected elevated levels of formate, citrate, and glycerophosphocholine (GPC), along with decreased concentrations of glutamine and myo-inositol. The OPLS-DA model showed stability, with R2Y = 69.7% and Q2 = 45.15%. Additionally, we observed differences in chemical shifts for leucine, myo-inositol, alanine, phenylalanine, and valine between CSF and plasma in patients with ALL.
Conclusions:
Our findings suggest that metabolomic analysis with 1H NMR is a promising tool for identifying potential molecular biomarkers and for deepening our understanding of metabolic reprogramming in pediatric ALL. The observed metabolic differences highlight the potential involvement of the central nervous system in the disease's pathophysiology.
