Acetaminophen for the Reduction of Oxidative Injury in Severe Sepsis (ACROSS)
Cell-free hemoglobin can be measured in the plasma of patients with sickle cell anemia, hemodialysis, after red blood cell transfusion, and in patients with sepsis. Cell-free hemoglobin in these patient population has been associated with poor outcomes, including an association with an increased risk of death. Acetaminophen may have a protective effect in these patient populations by inhibiting hemoprotein-mediated lipid peroxidation. The purpose of the present trial is to study the effect of acetaminophen on lipid peroxidation in adults with severe sepsis and detectable cell-free hemoglobin.
The primary hypothesis is that systemic markers of oxidative stress and lipid peroxidation, as measured by F2-isoprostanes, will be significantly lower in patients with severe sepsis and detectable cell-free hemoglobin who receive acetaminophen compared to placebo. The secondary hypothesis is that patients with severe sepsis and detectable cell-free hemoglobin treated with acetaminophen will have better clinical outcomes, including decreased incidence of acute kidney injury and lower rates of hospital mortality, compared to those who receive placebo.

|Official Title:||Phase IIa Randomized Controlled Trial of Acetaminophen for the Reduction of Oxidative Stress in Severe Sepsis|
- F2-isoprostanes After 72 Hours of Acetaminophen or Placebo [ Time Frame: 72 hours after randomization ]F2-isoprostanes are a marker of oxidative stress, specifically lipid peroxidation.
- In-hospital Mortality [ Time Frame: Patients will be followed through the end of their hospital stay, an average of 5 weeks ]
- Serum Creatinine After 72 Hours of Treatment With Acetaminophen or Placebo, Adjusted for Baseline Creatinine [ Time Frame: 72 hours ]

Patients will receive acetaminophen at the dose of 1 gram by mouth or by enteral feeding tube every six hours for a total of 72 hours.
Placebo Comparator: Placebo
Patients will receive placebo by mouth or by enteral feeding tube every six hours for 72 hours.
