Background: In 2016, Paul Marik published a study in Chest [2] demonstrating a decrease in hospital mortality of 32% for sepsis patients treated with vitamin C, thiamine and hydrocortisone.  The Marik protocol(as it has come to be known), entails IV vitamin C 1.5g q6hr for 4d + IV hydrocortisone 50mg q6hr for 7d + IV thiamine 200mg q12hr x4d. The authors’ hypothesis was that vitamin C, hydrocortisone, and thiamine have synergistic effects that reverse vasoplegic shock and potentially limit the duration of vasopressor treatment resulting in a reduction in organ and limb ischemia from vasopressors themselves.  Although the results of the study are promising, it is important to remember that this was only a hypothesis generating study.  We have been waiting for a randomized clinical trial to recreate the results of this study and finally we have our first of many… CITRIS-ALI. This randomized trial looks to see if high-dose vitamin C could reduce organ failure and biomarkers of inflammation and vascular injury in patients with sepsis and ARDS.

Background: The overall mortality in sepsis has decreased quite a bit in the last decade or so, however for a subset of patients, like those with Septic Shock, the mortality still remains high (as high as 50%).  There have been hundreds of studies trying to identify the holy grail to decrease mortality further, but one has not been found thus far.  Marik PE et al [1] published a study in Chest 2016 that has found a potential front runner.  In addition, the authors go on to say, in order to have an impact on a global scale, treatments would not only need to be effective, but also cheap, safe, and readily available; the authors of the following paper may have found just that..
