OBJECTIVE: To study the inflammatory factors in donor livers and its effect on recipient myocardial injury after liver transplantation recipients.
PATIENTS AND METHODS: Eighteen patients who underwent orthotopic liver transplantations between January 2014 and December 2015 in our hospital were selected. A portion of the hepatic venous blood of donor’s livers was preserved in heparinized tubes after partial resection. The concentrations of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), cardiac troponin I (cTnI), creatine kinase isoenzyme (CK-MB), and the activity of lactate dehydrogenase (LDH) in serum were measured. The concentrations of TNF-α, IL-6, cTnI, and CK-MB, and the activity of LDH in serum from the central venous blood of recipients were measured at several time points.
RESULTS: Persistent myocardial injuries were found in five patients, six experienced a transient increase of cardiac markers after surgery and returned to normal levels 24 h after surgery, and the others were normal. The comparison of the levels of inflammatory factors in serum between the five donors and recipients at different stages showed that the levels of myocardial markers of the donor livers which were supplied to the five cardiac injured patients were all significantly higher than those of other donor’s livers, while the levels of serum inflammatory factors in recipients showed no changes during the T0-T2 stage but increased significantly during T3-T5 (p < 0.05). The cardiac function after surgery was significantly different from that before surgery and that of the recipients without myocardial injury (p < 0.05).
CONCLUSIONS: Blood pressure changes before surgery may affect the levels of inflammatory factors in donor’s liver and cause postoperative myocardial injury in recipients. Proper hypotensive therapy for donors before partial liver resection can prevent postoperative myocardial injury in recipients.
