Glasgow coma score and tumor necrosis factor α as predictive criteria for initial poor graft function

Area of Science:

• Hepatology
• Transplantation Medicine
• Critical Care

Background:

• Initial poor graft function (IPGF) significantly impacts liver transplantation (LT) outcomes.
• Current methods for assessing graft dysfunction are often inaccurate due to the complexity of post-transplant courses.

Purpose of the Study:

• To identify reliable predictive criteria for retransplantation in patients undergoing liver transplantation.
• To evaluate the prognostic value of specific biomarkers and clinical scores in the early postoperative period.

Main Methods:

• Retrospective analysis of 42 liver transplant patients, including those with primary non-function (PNF) and delayed graft function (DGF).
• Patients were treated with the Molecular Adsorbent Recirculating System (MARS).
• Statistical analysis included stepwise multivariable logistic regression and Receiver Operating Characteristic (ROC) curve analysis.

Main Results:

• Tumor necrosis factor-alpha (TNF-α) was identified as an independent risk factor for retransplantation or death (OR 1.235, P = .013).
• Glasgow Coma Score (GCS) demonstrated a protective effect against retransplantation or death (OR 0.150, P = .003).
• A predictive model combining TNF-α and GCS showed superior predictive accuracy compared to individual variables on ROC analysis.

Conclusions:

• TNF-α and GCS are significant predictors of outcomes in liver transplant patients treated with MARS.
• A combined predictive model using TNF-α and GCS can aid clinicians in assessing prognosis and managing IPGF.
• Further validation in larger cohorts is recommended to solidify these findings for differentiating PNF and DGF outcomes.
