Abstract
- Aim: To determine the impact of Charlson comorbidity index (CCI) on waiting list (WL) and post liver retransplantation (LRT) survival.<br />Methods: Comparative study of all adult patients assessed for primary liver transplant (PLT) ( n = 1090) and patients assessed for LRT ( n = 150), 2000-2007 at our centre. Demographic, clinical and laboratory variables were recorded.<br />Results: Median age for all patients was 53 years and 66% were men. Median model for end stage liver disease (MELD) score was 15. Median follow-up was 7-years. For retransplant patients, 84 (56%) had ≥ 1 comorbidity. The most common comorbidity was renal impairment in 66 (44.3%). WL mortality was higher in patients with ≥ 1 comorbidity (76% vs 53%, P = 0.044). CCI (OR = 2.688, 95%CI: 1.222-5.912, P = 0.014) was independently associated with WL mortality. Patients with MELD score ≥ 18 had inferior WL survival (Log-Rank 6.469, P = 0.011). On multivariate analysis, CCI (OR = 2.823, 95%CI: 1.563-5101, P = 0.001), MELD score ≥ 18 (OR 2.506, 95%CI: 1.044-6.018, P = 0.04), and requirement for organ support prior to LRT ( P < 0.05) were associated with reduced post-LRT survival. Donor/graft parameters were not associated with survival ( P = NS). Post-LRT mortality progressively increased according to the number of transplanted grafts (Log-Rank 18.455, P < 0.001). Post-LRT patient survival at 1-, 3- and 5-years were significantly inferior to those of PLT at 88% vs 73%, P < 0.001, 81% vs 71%, P = 0.018 and 69% vs 55%, P = 0.006, respectively.<br />Conclusion: Comorbidity increases WL and post-LRT mortality. Patients with MELD ≥ 18 have increased WL mortality. Patients with comorbidity or MELD ≥ 18 may benefit from earlier LRT. LRT for ≥ 3 grafts may not represent appropriate use of donated grafts.<br />Competing Interests: Conflict-of-interest statement: No conflicts of interest relevant to this article were reported.
