Intravenous Vitamin C for COVID-19 Patients
In hospitalized patients with COVID-19, vitamin C had low probability of improving the primary composite outcome of organ support–free days and hospital survival. Enrollment was terminated after statistical triggers... read more
Adjunctive Intravenous Then Oral Vitamin C for CAP Patients
Patients hospitalised with community acquired pneumonia (CAP) have low peripheral blood vitamin C concentrations and limited antioxidant capacity. The feasibility of a trial of vitamin C supplementation to improve patient... read more
Sepsis is scurvy? Vitamin C, Thiamine, and Steroids
I have avoided commenting on vitamin C for sepsis, because commentary seemed rather unnecessary. The hype was obviously ridiculous. The chances of it helping were clearly low. The evidence of benefit was negligible. Others... read more
Intravenous Vitamin C Administration to Septic Shock Patients
Our pilot study indicated that intravenous vitamin C did not provide significant decreases in the mean dose or duration of vasopressor infusion. Further research that takes into account the potential impact of intervention... read more
Evaluating Vitamin C in Septic Shock
Vitamin C monotherapy failed to significantly reduce mortality in septic shock patients as hypothesized. Our findings do not support its routine clinical use for this purpose. Of 124 subjects receiving study drug and included... read more
Rapid Screening of Critically Ill Patients for Low Plasma Vitamin C Concentrations Using sORP
Hypovitaminosis C and vitamin C deficiency are common in critically ill patients and associated with organ dysfunction. Low vitamin C status often goes unnoticed because determination is challenging. The static oxidation... read more
High-dose Vitamin C in Critically Ill COVID-19 Patients
This pilot trial showed that high-dose intravenous vitamin C (HDIVC) failed to improve IMVFD28, but might show a potential signal of benefit in oxygenation for critically ill patients with COVID-19 improving PaO2/FiO2 even... read more
Effect of Vitamin C Infusion on Organ Failure and Biomarkers of Inflammation and Vascular Injury in Patients With Sepsis and ARDS
In this preliminary study of patients with sepsis and ARDS, a 96-hour infusion of vitamin C compared with placebo did not significantly improve organ dysfunction scores or alter markers of inflammation and vascular injury.... read more
Harm of IV High-Dose Vitamin C Therapy in Adult Patients
There is no consistent evidence that IV high-dose vitamin C therapy is more harmful than placebo in double-blind randomized controlled trials. However, reports of oxalate nephropathy, hypernatremia, glucometer error, and... read more
Effect of Vitamin C and Thiamine on Time Alive and Free of Vasopressor Support Among Patients With Septic Shock
A 2020 randomized trial reported no difference in duration of time alive and free of vasopressor administration at 7 days among intensive care unit (ICU) patients with septic shock assigned to vitamin C, thiamine, and hydrocortisone... read more
Wide Interest in a Vitamin C Drug Cocktail for Sepsis Despite Lagging Evidence
Critical care medicine specialist Paul Marik, MD, has described himself as a status quo destabilizer, and probably nothing illustrates that designation better than the sepsis treatment known as the Marik protocol. In the... read more
Effect of Vitamin C, Hydrocortisone, and Thiamine vs Hydrocortisone Alone on Time Alive and Free of Vasopressor Support Among Patients With Septic Shock
In patients with septic shock, treatment with intravenous vitamin C, hydrocortisone, and thiamine, compared with intravenous hydrocortisone alone, did not significantly improve the duration of time alive and free of vasopressor... read more
Study Suggests Benefits of Vitamin C for Severe Sepsis
More than 1.7 million Americans develop sepsis every year and incidence of the condition is on the rise. In severe cases, widespread inflammation leads to multiorgan failure and death. Results of a new study hold... read more
Update to the Vitamin C, Thiamine and Steroids in Sepsis (VICTAS) Protocol
The analyses described here are those necessary to answer the trial's primary question of whether combined treatment with vitamin C, thiamine and steroids is more effective than placebo in increasing days alive and free from... read more
Vitamin C for Sepsis
Dr. Alpha A. Fowler of Virginia Commonwealth University presented findings from the CITRIS-ALI trial that studied the role of vitamin C in patients with septic ARDS. The findings were presented @ESICM in Berlin and have just... read more
Vitamin C for Sepsis Suffers a Setback. Or a Step-Forward. It’s Complicated
The CITRIS-ALI study found no difference in primary outcomes among patients with sepsis treated with vitamin C versus placebo. But there was a difference in a secondary outcome - overall mortality. When it comes to sepsis... read more
Effect of Vitamin C Infusion on Organ Failure in Patients With Sepsis and ARDS
In this preliminary study of patients with sepsis and Acute Respiratory Distress Syndrome (ARDS), a 96-hour infusion of vitamin C compared with placebo did not significantly improve organ dysfunction scores or alter markers... read more
The Effect of Vitamin C on Clinical Outcome in Critically Ill Patients
In a mixed population of ICU patients, vitamin C administration is associated with no significant effect on survival, length of ICU or hospital stay. In cardiac surgery, beneficial effects on postoperative atrial fibrillation,... read more
Oxalate Nephropathy Following Vitamin C Intake within ICU
Compelling evidence obtained from in-vitro and animal studies suggest that vitamin C, a circulating antioxidant, may be a valuable adjunctive therapy in critically-ill patients. Data from humans are more conflicting.... read more
Ideas for Future Intensive Care
Progress toward determining the true worth of ongoing practices or value of recent innovations can be glacially slow when we insist on following the conventional stepwise scientific pathway. Moreover, a widely accepted but... read more
Metabolic sepsis resuscitation: the evidence behind Vitamin C
Sepsis resuscitation generally focuses on hemodynamics. Rivers of ink have been spilled writing about oxygen delivery and fluid responsiveness. This is clearly important, but it's possible that our focus on easily... read more
