Study summary

This is a randomized, double-blind, placebo controlled study to investigate the effect of intravenous thiamine (vitamin B1) on renal function in septic shock.

Read the detailed description

This is a randomized, double-blind, placebo controlled study to investigate the effect of intravenous thiamine (vitamin B1) on renal injury in septic shock. Patients admitted with septic shock who have a lactate of at least 2.0mmol/L and do not have pre-existing renal failure requiring dialysis will be eligible for the study. Enrolled patients will be randomized to intravenous thiamine 200mg twice daily for 6 doses or matching placebo. Blood will be drawn at several time points to assess biomarkers of renal injury. Secondary endpoints include need for renal replacement therapy, length of ICU stay, and hospital mortality.

What researchers measure

Primary outcomes

  1. Kidney Injury Biomarker

    Change in creatinine over time

    Time frame: Enrollment to 72-hours

Secondary outcomes

  1. Number of Participants Receiving Renal Replacement Therapy

    Number of participants who received renal replacement therapy in thiamine and placebo groups.

    Time frame: From date of enrollment until discharge from the intensive care unit (ICU) or date of death, whichever comes first, up to 60 days after enrollment

  2. ICU Free Days

    Days alive and free of the ICU through day 28

    Time frame: From date of enrollment until 28 days after enrollment

  3. In-hospital Mortality

    Length of hospital stay truncated at 60 days

    Time frame: From date of enrollment until discharge from the hospital or date of death, whichever comes first, up to 60 days after enrollment

  4. Number of Participants Experiences Acute Renal Failure

    Acute renal failure as defined by the KDIGO (Kidney Disease Improving Global Outcomes) AKI (Acute Kidney Injury) criteria. In brief, a patient can meet these criteria if their serum creatinine increases (for example, serum creatinine increases to 1.5x or higher of baseline serum creatinine, or if it crosses 4mg/dL), or if renal replacement therapy is initiated, or if urine output decreases (for example, \<0.5ml/kg/hour for 6-12 hours) or if patient becomes anuric (no urine production).

    Time frame: From date of enrollment until day of discharge from the index ICU admission or date of death, whichever comes first up until 60 days post-enrollment

  5. Change in Lactate Level

    Change in lactate level between enrollment and 72 hours after enrollment

    Time frame: From time of enrollment until 72 hours after enrollment

  6. Number of Participants With Delirium on Day 3

    Number of Participants with Delirium on Day 3 after enrollment

    Time frame: Day 3 after enrollment

  7. Change in the Sequential Organ Failure Assessment Score

    Change in Sequential Organ Failure Assessment Score (SOFA) score between enrollment and 72 hours after enrollment. SOFA scores are reported on a scale between 0-24, with 0 representing best outcome and 24 representing worst outcome.

    Time frame: Time of enrollment until 72 hours after enrollment

  8. Novel Biomarkers of Renal Injury

    KIM-1, NGAL, Cystatin-C at 24-hours after enrollment

    Time frame: 24 hours after enrollment
