Oxidant/antioxidant imbalance plays an important role in septic shock. The present study examined changes in circulating oxidative components in a neonatal sepsis model. Subjects were 14 newborn mixed-strain piglets randomly divided into two groups: a cecal ligation and perforation (CLP) model (n = 7) and sham (n = 7). Blood samples for total hydroperoxide (TH), biological antioxidant potential (BAP), tumor necrosis factor (TNF) α, interleukin (IL)-6, and IL-10 were collected pre-CLP and at 1, 3, and 6 h post-CLP. TH and BAP levels at 1 h post-CLP were significantly higher in the CLP group than in the sham group. In the CLP group, TH decreased gradually and reached baseline levels by 6 h post-CLP, while BAP remained elevated. Linear correlations were identified between serum TH and BAP at 1 h post-CLP, serum TH and TNF-α at 1 h post-CLP, and BAP and IL-6 at 6 h post-CLP. Changes in and correlations between circulating oxidative and inflammatory state components in a neonatal sepsis model were clarified. This is the first study to reveal that the presence of oxidant/antioxidant imbalance in sepsis and septic shock changes during the disease course.
