Clinical Trial Summary
This is a retrospective chart review that will measure the impact on outcomes in septic shock
patients who were resuscitated with a novel combination of medicines called iHAT (intravenous
hydrocortisone -ascorbic acid-thiamine). Septic shock patients treated with this combination
of drugs over the past two years will be compared with similar, concurrent septic shock
patients who were not treated with this drug given that adoption of this therapy has been
variable.
Description:
The condition of septic shock and multi-organ failure directly results from the rapid
consumption of ascorbic acid stores in humans suffering an infection (research in septic
patients have demonstrated near uniform deficiency/depletion of ascorbic acid on presentation
to ICU's).
This rapidly acquired ascorbic acid deficiency leads to shock and multi-organ failure due to
the fact that ascorbic acid is required for humans to produce endogenous vasopressors
(hormones that regulate blood pressure) as well as to maintain the function and integrity of
the endothelium-the endothelium is the largest organ in the body and is critical in
regulating blood pressure and preventing fluid leakage into all organs of the body, a
pervasive dysfunction which underlies "multi-organ failure". Oral administration of ascorbic
acid, even in high doses, has limited bioavailability (transporter mechanisms in the
intestines are limited) and does not lead to appreciable correction of the deficiency,
neither in the short term, nor in the critically ill.
In contrast, intravenous administration, in high doses, rapidly achieves not only normal
levels, but even supranormal levels.This critical need for intravenous supplementation to
treat septic shock was first argued for in 2006 by the European Respiratory Society's
"Consensus Committee on Intravenous (Parenteral) Vitamin C" a committee comprised of
scientists, researchers, and clinicians studying the role ascorbic acid in sepsis/shock
models from all over the world. This was followed by two randomized controlled trials in 2014
showing high efficacy of intravenous ascorbic acid in preventing death in septic shock
patients. In 2016, a highly publicized historical control trial further demonstrated a large
reduction in vasopressor duration, mortality and renal replacement therapy in a cohort of
patients after aggressively correcting ascorbic acid deficiency via the intravenous route
showing that multi organ failure and death is immediately prevented in almost all patients.
More recently, he has published a study demonstrating the synergistic effects of pairing
ascorbic acid with hydrocortisone--endothelial barriers are restored to a greater extent than
either agent alone.
Lastly, two trials in the past two years have shown that intravenous thiamine, when
systematically provided to the critically ill, independently leads to reduced mortality.
Thus, HAT therapy appears to be of high utility in preventing death and multi-organ failure
in septic shock. Beyond the above mentioned small, single center observational and randomized
controlled trials, no other outcome studies have been done in septic shock patients.
