Combination therapy of vitamin C and thiamine for septic shock: a multi-centre, double-blinded randomized, controlled study.

ABSTRACT: PURPOSE:To evaluate the effects of early combination therapy with intravenous vitamin C and thiamine on recovery from organ failure in patients with septic shock. METHODS:The ascorbic acid and thiamine effect in septic shock (ATESS) trial was a multi-centre, double-blind, randomized, controlled trial conducted in four academic emergency departments, enrolling adult patients with septic shock from December 2018 through January 2020. Patients were randomly assigned in a 1:1 ratio to either the treatment group [intravenous vitamin C (50 mg/kg, maximum single dose 3 g) and thiamine (200 mg) administration every 12 h for a total of 48 h] or the placebo group (identical volume of 0.9% saline with the same protocol). The primary outcome was ? Sequential Organ Failure Assessment (SOFA) score (SOFA score at enrolment-SOFA score after 72 h). Eighteen secondary outcomes were predefined, including shock reversal and 28-day mortality. RESULTS:A total of 111 patients were enrolled, of which 53 were assigned to the treatment group and 58 were assigned to the placebo group. There was no significant difference in ?SOFA scores between the treatment group and the placebo group [3, interquartile range (IQR) - 1 to 5 vs. 3, IQR 0-4, respectively, p?=?0.96]. Predefined secondary outcomes were also not significantly different between the groups. CONCLUSION:In this study, vitamin C and thiamine administration in the early phase of septic shock did not improve organ function compared with placebo, despite improvements in vitamin C and thiamine levels.

Project description:BackgroundThe combination therapy of hydrocortisone, vitamin C, and thiamine has been proposed as a potential treatment in patients with sepsis and septic shock. However, subsequent trials have reported conflicting results in relation to survival outcomes. Hence, we performed this randomized controlled trial (RCT) to evaluate the efficacy and safety of early combination therapy among adult patients with septic shock.MethodsThis single-center, double-blind RCT enrolled adult patients with diagnosis of septic shock within 12 h from Northern Jiangsu People's Hospital between February 2019 and June 2021. Recruited patients were randomized 1:1 to receive intervention (hydrocortisone 200 mg daily, vitamin C 2 g every 6 h, and thiamine 200 mg every 12 h) or placebo (0.9% saline) for 5 days or until ICU discharge. The primary endpoint was 90-day mortality. The secondary endpoints included mortality at day 28, ICU discharge, and hospital discharge; shock reversal; 72-h Delta SOFA score; ICU-free days, vasopressor-free days, and ventilator support -free days up to day 28; ICU length of stay (LOS) and hospital LOS.ResultsAmong 426 patients randomized, a total of 408 patients with septic shock were included in the per-protocol (PP) analysis, of which 203 were assigned to the intervention group and 205 to the placebo group. In the PP population, the primary outcome of 90-day mortality was 39.9% (81/203) and 39.0% (80/205) in the intervention and the placebo groups, respectively, and was not significantly different (P = 0.86). There was no significant difference between two groups in 28-day mortality (36.5% vs. 36.1%, P = 0.94) or the ICU mortality (31.5% vs. 28.8%, P = 0.55) and hospital mortality (34.5% vs. 33.2%, P = 0.78). No other secondary outcomes showed significant differences between two groups, including shock reversal, vasopressor-free days, and ICU LOS. Intention-to-treat analysis included all the 426 patients and confirmed these results (all P > 0.05).ConclusionAmong adult patients with septic shock, early use of hydrocortisone, vitamin C, and thiamine combination therapy compared with placebo did not confer survival benefits.

Project description:BackgroundThe objective of this study was to evaluate the clinical efficacy of thiamine and vitamin C with or without hydrocortisone coadministration on the treatment of sepsis and septic shock.MethodsMEDLINE, EMBASE and CENTRAL databases were searched for randomized controlled trials (RCTs) that made a comparative study between the combination therapy of vitamin C and thiamine with or without hydrocortisone and the administration of placebo in patients with sepsis or septic shock. Two reviewers independently performed study selection, data extraction and quality assessment. Both short-term mortality and change in the sequential organ failure assessment (SOFA) score from baseline (delta SOFA) were set as the primary outcomes. Secondary endpoints included intensive care unit (ICU) mortality, new onset of acute kidney injury, total adverse events, ICU and hospital length of stay, duration of vasopressor usage and ventilator-free days. Meanwhile, trial sequential analysis was conducted for primary outcomes.ResultsEight RCTs with 1428 patients were included in the current study. The results showed no significant reduction of short-term mortality in sepsis and septic shock patients who received combination therapy of vitamin C and thiamine with or without hydrocortisone compared to those with placebo {risk ratio (RR), 1.02 [95% confidence interval (CI), 0.87 to 1.20], p = 0.81, I 2 = 0%; risk difference (RD), 0 [95% CI, -0.04 to 0.05]}. Nevertheless, the combination therapy was associated with significant reduction in SOFA score [mean difference (MD), -0.63, (95% CI, -0.96 to -0.29, p < 0.001, I 2 = 0%] and vasopressors duration (MD, -22.11 [95% CI, -30.46 to -13.77], p < 0.001, I 2 = 6%). Additionally, there were no statistical differences in the pooled estimate for other outcomes.ConclusionsIn the current meta-analysis, the combination therapy of vitamin C and thiamine, with or without hydrocortisone had no impact on short-term mortality when compared with placebo, but was associated with significant reduction in SOFA score among patients with sepsis and septic shock.

Project description:Severe sepsis and septic shock are common in intensive care and carry high mortality rates. In patients with Gram-negative infections, early and extensive removal of endotoxin may limit the inflammatory response that characterizes septic shock. The Alteco® LPS Adsorber (hereafter referred to cited as the lipopolysaccharide (LPS) Adsorber) can be used for endotoxin removal and attenuate the deleterious inflammatory and clinical responses seen in septic shock.The Abdominal Septic Shock - Endotoxin Adsorption Treatment (ASSET) trial is a pilot study investigating the feasibility and safety of LPS Adsorber therapy. This pilot, multicenter, stratified, parallel, double-blinded, randomized, phase IIa, feasibility clinical investigation will be performed in five Scandinavian intensive care units. Thirty-two subjects with early septic shock and organ failure, following adequate resuscitation, will be randomized to receive either: extracorporeal veno-venous hemoperfusion therapy with the LPS Adsorber or veno-venous hemoperfusion therapy with a placebo adsorber (without active LPS-binding peptide). Patients will be stratified by infection focus such that 20 subjects with an abdominal focus (stratum A) and 12 subjects with a urogenital focus (stratum B) will be included in a parallel design. Thereafter, an interim analysis will be performed and an additional 12 patients may be included in the study. The study is designed as adaptive a priori: the patients from this study can be included in a later phase IIb study. The aim of the study is to investigate the feasibility of LPS Adsorber therapy commenced early in the time-course of septic shock. The primary endpoint will be a characterization of all reported unanticipated serious adverse device effects and anticipated serious adverse device effects. Secondary outcomes are decrease in endotoxin plasma concentration, impact on clinical outcome measures and impact on inflammatory response by LPS Adsorber therapy, as well as detailed description of the relevant mediators bound to the LPS Adsorber. Recruitment of patients will start in September 2015.The ASSET trial will give insight into the feasibility and safety of this LPS Adsorber therapy and preliminary data on its potential clinical effects in septic shock. Moreover, this pilot trial will provide with necessary data for designing future studies.ClinicalTrials.gov Identifier NCT02335723 . Registered on 28 November 2014.
