ABSTRACT
BACKGROUND AND AIMS: Transient elastography (TE) has routinely been implemented in the diagnosis and assessment of chronic liver disease. Little data are available in the post liver transplant (LTx) setting. METHODS: Three months after LTx, we performed TE in 137 liver transplant recipients and investigated its predictive value upon further clinical outcome. The mean follow-up time for clinical outcome was 24 months. RESULTS: Mean TE value was 10.6 kPa (± 6.3 kPa; range 2.8 - 29.9 kPa). There was a significant correlation between TE and aspartate aminotransferase (AST) (p=0.004), gamma-glutamyl transferase (GGT) (p=0.031) and bilirubin (p<0.001) serum levels. In Cox univariate analysis, TE served as a predictor of actuarial survival free of liver transplantation (OR=1.111, 95%CI: 1.051-1.174; p<0.001). In multivariate analysis, TE remained an independent risk factor associated with reduced actuarial survival free of liver transplantation (OR=1.080, 95%CI: 1.001-1.166; p=0.047), along with thrombocytes (OR=0.992, 95%CI: 0.986-0.999; p=0.020) and metabolic co-disease (OR = 0.250, 95%CI: 0.070-0.895; p=0.033). CONCLUSION: Transient elastography measurement at three months after LTx seems a robust predictor of survival in liver transplant recipients.

BACKGROUND: Multidrug-resistant (MDR) pathogens represent an emerging challenge in end-stage liver disease and in liver transplant recipients. METHODS: We evaluated the impact of MDR bacteria upon clinical outcomes in patients with end-stage liver disease (n = 777) at the time of enrollment on the liver transplant (LTx) waiting list, after first LTx (n = 645), and after second LTx (n = 128). RESULTS: Colonization/infection with MDR bacteria was present in 72/777 patients on the waiting list, in 98/645 patients at first LTx, and in 46/128 patients at second LTx. While on the LTx waiting list, the time until first hydropic decompensation (p = 0.021), hepatic encephalopathy (p < 0.001) and hepatorenal syndrome (p < 0.001) was reduced in the presence of MDR bacteria, which remained an independent risk factor of poor survival in multivariate analysis (p < 0.001). Following first and second liver transplant, MDR bacteria were associated with an increased risk of infection-related deaths (first LTx: p < 0.001; second LTx: p = 0.037) and reduced actuarial survival (first LTx: p < 0.001; second LTx: p = 0.046). CONCLUSIONS: We showed that MDR pathogens are associated with poor outcomes before, after first and after recurrent LTx.
