Abstract
Background: The effects of vitamin C on clinical outcomes in critically ill patients remain controversial due to inconclusive studies .Oxalic acid and oxalate toxicity have been shown to occur in myocardial tissue of patients with hereditary and possibly secondary hyperoxaluria . This retrospective observational cohort study evaluated the effects of vitamin C therapy on acute kidney injury (AKI) and mortality among septic patients.
Methods: Electronic medical records of 1390 patients from an academic hospital who were categorized
Results: Data revealed that vitamin C therapy was associated with increases in AKI (OR=2.07 95% CI [1.46-2.93]) and in-hospital mortality (OR= 1.67 95% CI [1.003-2.78]) after adjusting for demographic and clinical covariates. When stratified to examine ICU patients, vitamin C therapy remained a significant risk factor of AKI (OR=1.61 95% CI [1.09-2.39]) and provided no protective benefit against mortality (OR= 0.79 95% CI [0.48-1.31]). The authors recommend ongoing use of high dose vitamin C in sepsis should be appraised due to observed associations with AKI and death
