Abstract: In this review, we discussed the biological targets of carnitine, its effects on
immune function, and how L-carnitine supplementation may help critically ill patients.
L-carnitine is a potent antioxidant. L-carnitine depletion has been observed in prolonged
intensive care unit (ICU) stays, while L-carnitine supplementation has beneficial effects
in health promotion and regulation of immunity. It is essential for the uptake of fatty
acids into mitochondria. By inhibiting the ubiquitin-proteasome system, down-regulating
the apelin receptor in cardiac tissue, and reducing β-oxidation of fatty acid, carnitine may
decrease vasopressor requirement in septic shock and improve clinical outcomes of this
group of patients. We also reviewed animal and clinical studies that have been recruited
for evaluating the beneficial effects of L-carnitine in the management of sepsis/ septic
shock. Additional clinical data are required to evaluate the optimal daily dose and duration
of L-carnitine supplementation.
