Brief summary

In this study, we aim to determine whether the combination of Ascorbic Acid (Vitamin C), Thiamine (Vitamin B1), and Corticosteroids improves the trajectory of organ failure and reduces mortality in patients with sepsis and septic shock as compared to placebo.

Detailed description

Sepsis and Septic Shock are common and highly morbid clinical conditions without any specific therapy aside from antibiotics. A recent quasi-experimental study (Marik et. al., PMID 27940189) demonstrated a remarkable benefit when the combination of Ascorbic Acid (Vitamin C), Corticosteroids, and Thiamine (Vitamin B1) were given to patients with sepsis. In particular, patients who received this combination of medications required a shorter amount of time on vasopressors, suffered less organ failure, and had improved mortality. Vitamin C has long been suggested for treatment of patients with severe infection as it exerts significant anti-oxidant effects and reduces endothelial permeability. Corticosteroids, a mainstay of therapy for refractory shock in sepsis, have also been shown to enhance the beneficial cellular effects of vitamin C. Finally, thiamine has been shown to be an effective mitochondrial resuscitator in sepsis, especially for the \ 30% of septic shock patients who present with thiamine deficiency (Donnino et. al, PMID 26771781). In this study, we aim to reproduce the findings of Marik et. al. using a more rigorous study design (i.e. a blinded, randomized clinical trial) and focus on the important clinical outcomes of organ failure and death.

Interventions

DRUGvitamin C, vitamin B1, hydrocortisone

Vitamin C (1.5g) plus vitamin B1 (100mg) will be diluted in 100ml 0.9% NACL(normal saline) and administered IV every 6 hours for 4 days or until participant is discharged from the ICU.

Sequential Organ Failure Assessment (SOFA) Score at Baseline and 72 Hours

Sequential Organ Failure Assessment (SOFA) Score at Baseline and 72 Hours. The SOFA score ranges from a minimum of 0 to a maximum of 24, with higher scores meaning worse outcomes.

Time frame: Enrollment to 72-hours

Population: For the 72 hour SOFA score, patients who expired prior to that time point are excluded from the calculation of mean (SD) of the 72 hour SOFA score.

Comparison: The primary outcome was analyzed using a linear mixed-effects model where the correlation of within-patient repeated SOFA score measures was accounted for via the use of an unstructured variance-covariance matrix and linear contrasts. Covariates included age, sex, treatment group, time, and the interaction between treatment group and time. Study site was included as a random intercept. The model estimates the mean difference in SOFA score at 72 hours between treatment and control groups.p-value: 0.1295% CI: [-1.7, 0.2]Mixed Models Analysis
