Thiamine, Vitamin C and Hydrocortisone in the Treatment of Septic Shock

Overview

The purpose of this research study is to determine whether patients who receive thiamine (vitamin B1), vitamin C and hydrocortisone while in septic shock have improved outcomes compared to hydrocortisone alone. A recently published article "Hydrocortisone, Vitamin C and Thiamine for the treatment of Severe Sepsis and Septic Shock," suggested substantial mortality reduction (78%). We wish to test the hypothesis that mortality reduction is at least 25% in a prospective randomized trial. Other important sub-aims include the testing whether the protocol reduces the time on pressors agents, reduces the trajectory of the SOFA score, or reduces the trajectory of procalcitonin.

The study has four specific aims. The first is to utilize the Marik protocol published in CHEST to determine mortality reduction in septic shock with thiamine (vitamin B1), vitamin C and hydrocortisone supplementation. The second aim is to determine whether supplementation with thiamine, vitamin C and hydrocortisone reduce time spent on vasopressor support. Thirdly, whether the trajectory of the SOFA score is affected by supplementation with thiamine, hydrocortisone and vitamin C. Fourthly, assess the trajectory of procalcitonin, a laboratory test, in patients treated with the protocol. This is a single center community based hospital in Southwest Michigan, investigator blinded, randomized placebo controlled trial, 24 month, parallel group, two arm, superiority study with a 1:1 allocation ratio to compare the efficacy of thiamine, vitamin C and hydrocortisone in the treatment of severe sepsis and septic shock. Each arm of the research study will contain 30 patients in order to detect a 25% mortality reduction. Enrollment for this study will be initiated in patients with septic shock that require addition of a second pressor agent. The control arm of our randomized trial will receive a second pressor agent, hydrocortisone and standard of care. If the patient needs additional pressor support or therapy, that will be recorded in the results. The experimental arm will receive a second pressor agent and hydrocortisone, plus thiamine and vitamin C along with the standard of care. If the patient needs additional pressor support or therapy that will be recorded in the results. To clarify, both arms will utilize two vasopressor agents, hydrocortisone and supportive care, the experimental group will also receive vitamin C and thiamine.
