Abstract
BACKGROUND/ PURPOSE: Dyslipidemia is common in liver transplant recipients. This retrospective study investigates whether donors play a role. METHODS: Prospectively collected data of donors and recipients of deceased-donor liver transplantation (DDLT) and living-donor liver transplantation (LDLT) were reviewed. Total cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein (HDL) and fasting glucose were compared between groups. HDL ≥1.6 mmol/L at 2 years after transplant was considered the marker of a favorable post-transplant lipid profile in recipients. Univariate and multivariate analyses were performed to identify predictive factors for this marker. RESULTS: There were 85 DDLTs and 80 LDLTs. LDLT donors were younger (30 vs. 50 years, p < 0.001) and lighter (58.2 vs. 63.4 kg, p = 0.008) and had a lower body mass index (21.2 vs. 23.7, p < 0.001). The DDLT group had more fatty grafts (p = 0.001) and longer cold (375 vs. 103.5 min, p < 0.001) and warm (50.5 vs. 46 min, p = 0.034) ischemia. LDLT donors had lower fasting glucose (4.85 vs. 7.21 mmol/L, p < 0.001) and triglyceride (0.87 vs. 1.22 mmol/L, p = 0.016) but higher HDL (1.58 vs. 1.39 mmol/L, p = 0.022). LDLT recipients also had higher HDL at 1 year (1.48 vs. 1.28 mmol/L, p = 0.026) and 2 years (1.43 vs. 1.21 mmol/L, p = 0.008). Fourteen (16.5%) DDLT recipients and 27 (33.8%) LDLT recipients had HDL ≥1.6 mmol/L at 2 years. On multivariate analysis, donor HDL ≥1.6 mmol/L (RR 4.311, 95% CI 1.666-11.158, p = 0.003) and recipient body mass index <24 (RR 2.753, 95% CI 1.064-7.127, p = 0.037) were the two independent predictive factors. CONCLUSION: LDLT recipients had better lipid profiles than DDLT recipients. The feature of high HDL level in donors was transferred to recipients.
