Peripheral Blood Mononuclear Cells Demonstrate Mitochondrial Damage Clearance During Sepsis.

ABSTRACT: OBJECTIVES:Metabolic derangements in sepsis stem from mitochondrial injury and contribute significantly to organ failure and mortality; however, little is known about mitochondrial recovery in human sepsis. We sought to test markers of mitochondrial injury and recovery (mitochondrial biogenesis) noninvasively in peripheral blood mononuclear cells from patients with sepsis and correlate serial measurements with clinical outcomes. DESIGN:Prospective case-control study. SETTING:Academic Medical Center and Veterans Affairs Hospital. PATIENTS:Uninfected control patients (n = 20) and septic ICU patients (n = 37). INTERVENTIONS:Blood samples were collected once from control patients and serially with clinical data on days 1, 3, and 5 from septic patients. Gene products for HMOX1, NRF1, PPARGC1A,
