- Brief Summary
A randomized controlled trial to test the synergic modulation effect of vitamin C, thiamine and hydrocortisone in patients with severe sepsis or septic shock.
- Detailed Description
Management of sepsis bases on three components: infection control, haemodynamic stabilization and modulation of the septic response. Many clinical trials conducted agents to block the inflammatory cascade, such as corticosteroids, anti-endotoxins antibodies, tumor necrosis factor (TNF) antagonists, interleukin-1-receptor antagonists, and so on, but none has proven effective to date. A safe, effective, ready available therapy is desperately required. Thiamine is a key co-factor for pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, and transketolase. All the three enzymes are required to complete Krebs Cycle to prevent from lactate production. Previous studies have found thiamine deficiency to be prevalent in septic shock and other critically ill conditions. One pilot study also proved patients with septic shock and baseline thiamine deficiency would have significant lower lactate level at 24 hours after administration of thiamine. HYPRESS (hydrocortisone for Prevention of Septic Shock) study failed to demonstrate an outcome benefit from a hydrocortisone infusion in patients with sepsis. Vitamin C is a potent antioxidant that directly scavenges oxygen free radicals, can restores other cellular antioxidants and plays a role in preserving endothelial function and microcirculatory flow as well. Though previous studies suggested that hydrocortisone and vitamin C alone have little impact on the clinical outcome of patients with sepsis. Vitamin C and hydrocortisone have many overlapping and synergic pathophysiologic effects in sepsis. Both drugs are required for the synthesis of catechlamines and increase vasopressor sensitivity. Both drugs can down-regulating the production of proinflammatory mediators, increase tight junctions between endothelial and epithelial cells, preserve endothelial function and microcirculatory flow. Marik et al published their study in CHEST (June 2017) resulting the benefits of combination of Vitamin B1, Vitamin C and hydrocortisone to severe sepsis and septic shock. However, small sample size and some bias due to imbalanced baseline and study method could confound the results. Herein, we would like to lead a randomized controlled trial to test the synergic modulation effect of vitamin C, thiamine and hydrocortisone in patients with severe sepsis or septic shock.

Group Intervention Description ABC group (Ascorbic acid-Vitamin B1-Hydrocortisone) group Ascorbic acid-Vitamin B1-Hydrocortisone patients in study group, so called" ABC" (Ascorbic acid-Vitamin B1-Hydrocortisone) group, would receive intravenous Thiamine (200mg in 50 mL of 0.9% normal saline and was administered as a 30-min infusion every 12 hours for 4 days or until ICU discharge), Vitamin C (1.5g mixed in a 100-mL solution of normal saline and was administered as an infusion over 30 to 60 min every 6 hours for four days or until ICU discharge) as well as hydrocortisone 50mg every 6 hours (or other equivalent products) for 7 days normal saline group Placebo patients would receive 50mL 0.9% normal saline, 100 mL 0.9% normal saline with the same infusion rate and hydrocortisone dependent on the discretion of the attending physician
