High Dose Intravenous Ascorbic Acid in Severe Sepsis

• Status: Terminated
• Trial end date: 2017-11-23
• Target enrollment: 0
• Participant gender: All

Summary

Despite an organized treatment approach outlined in expert-consensus guidelines for sepsis with fluid resuscitation to treat hypovolemia, antibiotics to target the infectious insult, and vasopressors for hypotension, mortality rates for sepsis remain high and the incidence continues to rise, making sepsis the most expensive inpatient disease.

1. Recent research has described the therapeutic benefits associated with ascorbic acid treatment for sepsis.

2. Researchers objectives are to perform a randomized-controlled clinical trial investigating the ability of ascorbic acid(vitamin C) administration to decrease organ dysfunction in severe sepsis. The widespread occurrence of microvascular dysfunction in sepsis leading to tissue hypoxia, mitochondrial dysfunction, and adenosine triphosphate (ATP) depletion, gives rise to organ failure.

3. Patients with organ failure and sepsis (severe sepsis) are at a higher risk of death than patients with organ failure alone. Critically ill patients may have an increased requirement for ascorbic acid in sepsis and these patients frequently have levels below normal. Ascorbic acid administration, has been shown to correlate inversely with organ failure (human literature) and directly with survival (animal studies).

4,5 Intravenous ascorbic acid therapy decreases organ failure by providing a protective effect on several microvascular functions including improving capillary blood flow, decreasing microvascular permeability, and improving arteriolar responsiveness to vasoconstrictors. Defining the utility of novel agents to augment researchers care for severe sepsis is an important task as investigators continue the institutional focus on sepsis care.
