摘要

Several donor-specific factors influence the functional recovery and long-term outcomes of liver grafts. This study investigated the association between donor fasting glucose (DFG) and recipient outcomes after living donor liver transplantation (LDLT) in 950 cases at a single center. Patients were divided into two groups: low-DFG (< 85 mg/dL, n = 120) and control (≥ 85 mg/dL, n = 830). The five-year graft survival rate was significantly lower in the low-DFG group (71.5%) compared to the control group (80.0%) (P = 0.02). Multivariable Cox regression analysis showed that low DFG was independently associated with graft loss (hazard ratio 1.72, 95% CI 1.15–2.56, P = 0.008). In propensity score-matched groups, the low-DFG group also had lower survival rates (71% vs. 83.1%, P = 0.004). The presence of additional risk factors, such as low graft-to-recipient weight ratio, older donor age, and longer cold ischemic time, further reduced graft survival in the low-DFG group. A DFG level < 85 mg/dL is associated with higher risk of graft failure after LDLT, especially when combined with other risk factors. Low DFG should be considered a prognostic marker in LDLT planning, with potential to improve patient outcomes as further research clarifies the underlying pathophysiological mechanisms.
