Peri- and post-operative course of cytokines and the metabolic activity of neutrophils in human liver transplantation
Peri- and post-operative (up to day 7 after surgery) neutrophil chemiluminescence and the plasma concentrations of interleukin 6 (IL-6), IL-8, IL-10 and tumour necrosis factor alpha (TNF-alpha) were evaluated in the blood of patients undergoing liver transplantation. IL-6, IL-8 and IL-10 levels increased during early reperfusion and then returned to normal mostly within the first post-operative day. TNF-alpha was increased during the whole period observed. Spontaneous as well as activated neutrophil chemiluminescence was depressed in early reperfusion and remained low during the whole period followed. Samples collected during early reperfusion provided positive correlation for IL-6 vs IL-8 as well as for IL-6 and IL-8 vs chemiluminescence. The data were also evaluated with respect to the outcome of transplantation. Since IL-8, IL-10 and TNF-alpha levels increased significantly during the first post-operative week, mainly in a group of patients who developed serious complications within the first mouth after surgery, we proved a connection between peri- and early post-operative induction of cytokine release and the outcome of liver allograft transplantation.
