This study is designed to determine if Vitamin C administration to septic patients will result in an improvement in organ dysfunction which occurs during a septic illness.

Hypothesis: 1. Vitamin C in sepsis will reduce the injury to organs 2. Vitamin C will reduce the length of time on a ventilator, length of stay in the intensive care unit and in hospital.

Condition Intervention Phase
Severe Sepsis
Drug: Vitamin C
Drug: placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Pilot Study Examining the Efficacy of Vitamin C Administration in Septic Patients.

Further study details as provided by Michael Sharpe, Lawson Health Research Institute:

Primary Outcome Measures:
  • Sequential organ function assessment score (SOFA) [ Time Frame: 28 days or discharge from intensive care unit ]
    Scoring system to determine the extent of a patient's organ function or rate of failure. The score based on 6 different scores; one each for respiratory, hepatic, cardiovascular, renal, coagulation, neurologic.

Secondary Outcome Measures:
  • Biomarkers as a measure of coagulation, inflammation and oxidative stress. [ Time Frame: 28 days or discharge from intensive care unit ]
    Vitamin C Assays - Plasma/WBC Cytokines (8- plex) Adhesion Molecules Procalcitonin C-Reactive Protein,H igh Sensitivity High Density Lipoprotein Cholesterol Tbars F2 isoprostane Neutrophil elastase Thrombomodulin Free DNA HIF-1α

Estimated Enrollment: 20
Study Start Date: May 2012
Estimated Study Completion Date: September 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vitamin C
Intravenous Vitamin C will be administered (1 gram) every 8 hours for 28 days or discharge from intensive care unit
Drug: Vitamin C
Intravenous Vitamin C 1 gram every 8 hours for 28 days or discharge from intensive care unit
Placebo Comparator: placebo
placebo vehicle administered in same fashion as active treatment
Drug: placebo
placebo vehicle administered to match volume of treatment drug every 8 hours for 28 days or until discharge from ICU

Detailed Description:
This study will measure biomarkers of inflammation, coagulation and oxidative stress. These biomarkers have been shown to be increased during periods of oxidative stress eg post-operative, trauma, sepsis. The investigators will determine if Vitamin C administration decreases oxidative stress and as a result, a decrease in the markers of organ dysfunction eg SOFA Scores. Ultimately, if the investigators show a decrease in injury to organs, will this result in a better outcome for patients.
