Summary

This trial evaluates HAT therapy, which combines Hydrocortisone, Vitamin C, and Vitamin B1, in patients with severe infections like NSTI and sepsis. The treatment aims to reduce inflammation, support the immune system, and improve cell function. Hydrocortisone has been used in various treatments due to its anti-inflammatory properties, but its effectiveness can vary depending on the condition being treated.

Who is the study for?
This trial is for adults with sepsis and necrotizing soft tissue infections needing ICU care and surgery. It's not for those under 18, pregnant or breastfeeding women, prisoners, people with severe chronic diseases expected to live less than 30 days unrelated to sepsis, or anyone allergic to the study drugs. Participants must weigh over 40 kg and cannot be using high-dose vitamin C.
What is being tested?
The trial tests HAT therapy (a combination of vitamin C, thiamine, and corticosteroids) against a placebo in patients with acute necrotizing soft tissue infections (NSTI) complicated by sepsis. The goal is to see if HAT improves patient outcomes compared to a non-active treatment.
What are the potential side effects?
Possible side effects include reactions related to high doses of vitamins such as stomach upset or kidney stones in susceptible individuals. Corticosteroids can cause increased blood sugar levels, mood changes, insomnia, and higher infection risk.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Treatment ArmExperimental Treatment1 Intervention
Patients will be enrolled within 24 hours of diagnosis of sepsis related to a necrotizing soft-tissue infections (NSTI). HAT will be initiated within 4 hours of enrollment (thus treatment with HAT can occur no later than 28 hours from diagnosis). Per Dr. Marik's original study, HAT consists of: 1. 1.5 g vitamin C every 6 hours for 4 days or until ICU discharge 2. 50 mg hydrocortisone every 6 hours for 7 days or until ICU discharge (followed by a taper over 3 days) 3. 200 mg thiamine every 12 hours for 4 days or until ICU discharge In our study, due to the prolonged ICU course typical of most patients with NSTIs, it is not felt feasible to continue indefinitely "until ICU discharge." Thus, treatment will be continued for 4 to 7 days plus a 3 day taper (respectively) as above, with no plan for a longer duration of treatment.
Group II: Control ArmPlacebo Group1 Intervention
The control arm will receive the same standard ICU care for NSTI but will not receive HAT. They will receive a placebo consisting of normal saline, indistinguishable to the treatment team (blinded) but known to the pharmacy team (unblinded to treatment and placebo groups). This is so that if the treatment team elects to give stress dose steroids, they can be administered without breaking protocol (i.e. if the patient is getting HAT, it includes steroids, so if the treating team wanted to start hydrocortisone - because they didn't know if the patient was on HAT or placebo and felt steroids were indicated - the pharmacist could ensure the patient was on steroids one way or another without unblinding the providers).

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
HAT therapy for sepsis includes hydrocortisone, ascorbic acid (vitamin C), and thiamine, each targeting different aspects of the disease. Hydrocortisone reduces inflammation by suppressing the immune response, which is crucial to prevent tissue damage. Ascorbic acid acts as an antioxidant, reducing oxidative stress and protecting cells from free radical damage. Thiamine supports cellular metabolism and energy production, which can be impaired in sepsis. These treatments are important as they address key pathological processes in sepsis, potentially improving patient outcomes by stabilizing cellular function, reducing inflammation, and mitigating oxidative damage.
