Evaluation of Preoperative and Postoperative S100β and NSE Levels in Liver Transplantation and Right Lobe Living-Donor Hepatectomy: A Prospective Cohort Study

Background and aims. This study aimed to evaluate plasma neuron-specific enolase (NSE) and S100 beta levels in orthotopic liver transplantation. Materials and methods. A total of 56 patients who underwent orthotopic liver transplantation were divided into 3 groups. Healthy donors (group D), end-stage liver failure (ESLF) patients (recipient, group R), and ESLF patients diagnosed with hepatic encephalopathy (HE, group HE). Prognosis, preoperative routine laboratory findings, serum NSE, and S100 beta in samples obtained preoperation and first and sixth months postoperation were analyzed. Results. Serum NSE and S100 beta levels were significantly higher in ESLF patients compared to healthy donors, particularly during the preoperative period. There was a significant decrease in serum NSE and S100 beta in ESLF patients during the postoperative measurement periods compared to preoperative levels. Serum NSE and S100 beta levels measured at 3 different time points showed no significant difference between ESLF patients and ESLF patients with HE. However, the recent Model of End-Stage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP) scores showed a significant correlation with serum NSE and S100 beta in ESLF patients diagnosed with HE. Serum NSE and S100 beta levels in healthy donors significantly increased within the first month following hepatectomy and decreased in the sixth month following surgery. Conclusion. Although serum NSE and S100 beta levels significantly decreased with improved liver function in recipients following liver transplantation, there was no complete recovery within 6 months after surgery. The increase in serum levels of NSE and S100 beta in donors measured following hepatectomy was detected to remain slightly higher in the sixth postoperative months.

Automated summary

This study evaluated plasma neuron-specific enolase (NSE) and S100 beta levels in orthotopic liver transplantation, finding that levels were significantly higher in ESLF patients preoperatively and decreased postoperatively. NSE and S100 beta levels correlated significantly with MELD and CTP scores in ESLF patients with HE. Levels in healthy donors increased in the first month post-hepatectomy and decreased by the sixth month.
