title: Systemic liberation of interleukin-1 beta and interleukin-1 receptor antagonist in the perioperative phase of liver transplantation.
abstract: We measured systemic serum levels of interleukin-1 receptor antagonist (IL-1ra), interleukin-1 beta (IL-1 beta), tumor necrosis factor alpha (TNF-alpha), and interleukin-6 (IL-6) during the preoperative, anhepatic, and postreperfusional phases up to the 7th postoperative day in 60 patients undergoing orthotopic liver transplantation (LTx). In contrast to IL-1 beta, IL-1ra, TNF-alpha, and IL-6 showed a significant elevation in relation to the early phase after reperfusion, while TNF-alpha displayed a high grade of scatter. In addition, IL-1ra levels were significantly elevated during the anhepatic phase. Maximum serum levels were found at 15 min after reperfusion, 120 min after reperfusion, and on the 1st postoperative day, respectively. Serum levels decreased considerably at 24 h and 7 days after reperfusion. The comparative monitoring of systemic cytokine and cytokine antagonist levels, in particular the liberation of IL-1ra and IL-6 may provide useful parameters for the development of new liver preservation theories for LTx.
