Sepsis is a systemic inflammatory state associated with acute kidney injury (AKI) and high mortality. However, sepsis-induced AKI cannot be effectively prevented or treated using current antimicrobial therapies and supportive measures. We explored the therapeutic effect of newly developed fructose esters on sepsis-induced AKI (S-AKI). ⋯ Our data suggest that FDL, with its antioxidant activity against H2O2, can neutralize LPS toxicity using a high binding affinity, and attenuate S-AKI by inhibiting caspase 1 mediated pyroptosis, thereby ameliorating renal oxidative stress and dysfunction.

Thiamine and ascorbic acid have been proposed to mitigate the devastating consequences of sepsis and septic shock. To date, randomized controlled trials have failed to demonstrate a benefit of these therapies and heterogeneity of treatment effect is suspected. In this study, we aimed at assessing the heterogeneity of treatment effect of thiamine (B1) and the combination of B1 plus ascorbic acid (AA + B1) in critically ill patients with sepsis. ⋯ These results reinforce the lack of efficacy of the combination of AA + B1 reported in recent trials and even raise concerns about potential harm in older patients with comorbidities. On the contrary, we reported improved ICU survival associated with B1 supplementation in the most severe patients and those with predominant respiratory failure, supporting the need for further trials in this specific population.
