Intravenous ascorbic acid to prevent and treat cancer-associated sepsis?

ABSTRACT: The history of ascorbic acid (AA) and cancer has been marked with controversy. Clinical studies evaluating AA in cancer outcome continue to the present day. However, the wealth of data suggesting that AA may be highly beneficial in addressing cancer-associated inflammation, particularly progression to systemic inflammatory response syndrome (SIRS) and multi organ failure (MOF), has been largely overlooked. Patients with advanced cancer are generally deficient in AA. Once these patients develop septic symptoms, a further decrease in ascorbic acid levels occurs. Given the known role of ascorbate in: a) maintaining endothelial and suppression of inflammatory markers; b) protection from sepsis in animal models; and c) direct antineoplastic effects, we propose the use of ascorbate as an adjuvant to existing modalities in the treatment and prevention of cancer-associated sepsis.

Project description:Fluid responsiveness is proposed as a physiology-based method to titrate fluid therapy based on preload dependence. The objectives of this study were to determine if a fluid responsiveness protocol would decrease progression of organ dysfunction, and a fluid responsiveness protocol would facilitate a more aggressive resuscitation.Prospective, 10-center, randomized interventional trial.suspected sepsis and lactate 2.0 to 4.0?mmol/L. Exclusion criteria (abbreviated): systolic blood pressure more than 90?mmHg, and contraindication to aggressive fluid resuscitation.fluid responsiveness protocol using Non-Invasive Cardiac Output Monitor (NICOM) to assess for fluid responsiveness (>10% increase in stroke volume in response to 5?mL/kg fluid bolus) with balance of a liter given in responsive patients.standard clinical care.primary-change in Sepsis-related Organ Failure Assessment (SOFA) score at least 1 over 72?h; secondary-fluids administered. Trial was initially powered at 600 patients, but stopped early due to a change in sponsor's funding priorities.Sixty-four patients were enrolled with 32 in the treatment arm. There were no significant differences between arms in age, comorbidities, baseline vital signs, or SOFA scores (P?>?0.05 for all). Comparing treatment versus Standard of Care-there was no difference in proportion of increase in SOFA score of at least 1 point (30% vs. 33%) (note bene underpowered, P?=?1.0) or mean preprotocol fluids 1,050?mL (95% confidence interval [CI]: 786-1,314) vs. 1,031?mL (95% CI: 741-1,325) (P?=?0.93); however, treatment patients received more fluids during the protocol (2,633?mL [95% CI: 2,264-3,001] vs. 1,002?mL [95% CI: 707-1,298]) (P?<?0.001).In this study of a "preshock" population, there was no change in progression of organ dysfunction with a fluid responsiveness protocol. A noninvasive fluid responsiveness protocol did facilitate delivery of an increased volume of fluid. Additional properly powered and enrolled outcomes studies are needed.
