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.
