- The derangement in oxygen utilization occurring during sepsis is likely to be linked to impaired mitochondrial functioning. Skeletal muscle comprises 50%–60% of body cell mass and represents the largest organ potentially affected by systemic inflammation. Thus, we investigated whether sepsis induced by cecal ligation and puncture (CLP) modifies mitochondrial activity in respiratory and nonrespiratory skeletal muscle.
- Some of the postulated molecular mechanisms of sepsis progression are linked with the imbalance between reactive oxygen species (ROS) production and its degradation by cellular antioxidant pathways. Some studies have correlated plasma oxidative stress, inflammatory markers, and clinical markers of organ failure, but none performed this in a systematic way, determining in situ oxidative and inflammatory markers and correlating these with markers of organ failure.
