Vitamin C, Hydrocortisone and Thiamine in Patients With Septic Shock
- Registration Number
- NCT05192213
- Lead Sponsor
- Hospital Sirio-Libanes
- Brief Summary
A great interest exists regarding substances with an immunomodulatory effect for sepsis patients. Recent data have shown that intravenous vitamin C, together with corticosteroids and thiamine, could prevent progressive organ dysfunction and reduce vasopressor use in patients with severe sepsis and septic shock. Its effect on mortality, on the other hand, is yet to be demonstrated. The Vitamins study aims to conclusively determine, through its prospective, multicentre and double-blinded design including 1090 patients, wether Vitamin C, Thiamine and Hydrocortisone in combination can reduce mortality in patients with septic shock.
- Detailed Description
The global burden of sepsis is substantial with an estimated 15 to 19 million cases per year, most occurring in low-income countries. With recent advances in diagnosis and supportive treatment, the 28-day mortality from sepsis in high-income countries has decreased by about 25%; however, the mortality from septic shock still remains around 45%.
A large volume of experimental data has shown that both corticosteroids and intravenous vitamin C attenuate the release of pro-inflammatory mediators, reduce the endothelial lesion characteristic of sepsis (reducing endothelial permeability and improving microcirculatory flow), increase the release of endogenous catecholamines and improve vasopressor reaction. In animal models, these effects resulted in reduced organ damage and increased survival. However, its effect on critically ill humans is controvert. Results of a retrospective study brought that the early use of intravenous vitamin C, together with corticosteroids and thiamine, can prevent progressive organ dysfunction and can reduce mortality in patients with severe sepsis and septic shock.
For this reason, the investigators propose a randomized, controlled, multicentre (mcRCT), pragmatic and feasibility study to investigate whether Vitamin C (1.5g 6 / 6h), along with thiamine (200 mg, 12 / 12h) and hydrocortisone (50 mg 6 / 6h) for 7 days can reduce all-cause mortality within 28 days after randomization.

Group Intervention Description Control Placebo Placebo 1 for vitamin C every 6 hours + Placebo 2 for thiamine every 12 hours + 50 mg of hydrocortisone every 6 hours For 7 days or until patient's discharge/death Intervention Vitamin C 1,5 g of vitamin C every 6 hours + 200 mg of thiamine every 12 hours + 50 mg of hydrocortisone every 6 hours For 7 days or until patient's discharge/death
- Primary Outcome Measures
Name Time Method 28-day Mortality 28 days Mortality by all causes at 28 days after randomization
- Secondary Outcome Measures
Name Time Method Quality of life assessment 6 months Difference in quality of life assessment using the EQ-5D questionnaire, from EuroQol Group. The questionnaire will be applied during intensive care unit (ICU) stay and after 6 months. Range 0-1, with 0 and 1 corresponding to death and full health, respectively. This will be applied in 30% of research sample.
90-day Mortality 90 days Mortality by all causes at 90 days after randomization
Delta SOFA 72 hours Change in total Sequential Organ Failure Assessment (SOFA) score, comparing SOFA score at 72 hours and SOFA score at randomisation. Range 0-24. Lower SOFA scores represent better outcome.
Duration of support 28 days Duration of use of vasoactive drugs, mechanical ventilation and renal replacement therapy
