Ceramide concentrations in septic patients: A possible marker of multiple organ dysfunction syndrome

These observations suggest that mononuclear cells of peripheral blood from patients with sepsis are committed to undergo apoptosis, because there is evidence that ceramide acts as an endogenous mediator of apoptosis. The strong correlation we found between cell-associated ceramide and serum TNF-alpha supports the hypothesis that this cytokine plays an important role in activating the sphingomyelin pathway and ceramide generation in patients with sepsis. In addition, this study provides evidence that consistent concentrations of mononuclear cell-associated ceramide may predict progression toward MODS in septic patients.
