Our results showed that the uremia group presented an increased trend over time in the serum cytokines TNF-α, IL-6, and IL-10, the serum D-LA and DAO, and the intestinal permeability, and these biomarkers were higher than those in the control group at all the investigated time points, especially in postoperative week 8 and/or 10. Here, IL6 is linked to uremia.
