Abstract

Patients undergoing mFOLFOX6 treatment were classified into a hyperammonemia group (NH3 group) or a non-hyperammonemia group (Non-NH3 group) in order to investigate risk factors related to the onset of hyperammonemia. The NH3 group demonstrated significantly lower lymphocyte counts, hemoglobin and albumin levels, and estimated glomerular filtration rates compared to the Non-NH3 group, suggesting that the NH3 group was experiencing renal dysfunction and loss of skeletal muscle mass due to malnutrition. Amino acid fractionation in the NH3 group revealed high urea levels, and delayed urea excretion was identified. Fluorocitric acid, a fluorouracil metabolite, inhibits aconitase in the tricarboxylic acid cycle. In addition, decreased renal urea transporter function due to renal impairment leads to delayed urea excretion. These factors may induce secondary decreases in urea cycle function, leading to hyperammonemia.
