Aim: Liver allografts of viremic OLT have a higher risk of failure. Timely intervention is necessary. However, long-term outcome reports, especially using newer agents, is lacking. Methods: In a 10-year period, we compared: 19 OLT Rx, for 12 weeks, with TVR + Pegylated interferons (P-IFN) + Ribavirin (RBV) followed with conventional Rx (C-Rx, P-IFN+RBV) for 12-36 weeks. Controls (n=19) received C-Rx for 48 weeks. Matching done for age, gender, genotype (all 1), race, OLT date, non-responders (NR), SVR, immunosuppression (tacrolimus + Mycophenolic acid) and survival. Rx criteria HCVR histology (bx, stages 0-3, Batts&Ludwig classification). Pre and post Rx bx + annual bx and 3-year minimum follow up. Laboratory tests, graft and OLT survivals analyzed. Statitistics: t-, Chi2-tests. Results: No demographic , survival (matched controls) or laboratory differences found. Of note, 13/19 (68%) in TVR group were OLT NR to previous C-Rx. At 3+ years of follow up, there was significantly more HCVR progression in OLT TVR NR than TVR SVR (p < 0.05). Controls also showed differences in HCVR progression, although NS.

Liver Allograft Stage Changes with HCV Therapy
	Telaprevir + PegIFN +Ribavirin Rx		PegIFN + Ribavirin
	Non Responders	SVR	Non Responders	SVR
	(n = 6)	(n = 13)	(n = 6)	(n = 13)
PreRx Stage	1.5±0.6*	1.7±1.3	2.0±0.9	1.9±0.9
EndRx Stage	2.2±0.8	2.6±1.3	2.8±1.2	2.0±
Last Follow up Stage	2.7±0.8*	2.1±1.4	2.8±1.2	2.0±
PreRx to Last Bx Difference	1.2±0.8**	0.4±0.7**	0.8±1.0	0.2±1.1

t-test: No differences, except * and **.Conclusions: With at least 3 years of follow up, HCV OLT SVR who received TVR triple Rx showed less HCVR progression. This benefit is in addition to the fact that 2/3 of OLT on TVR Rx had previously failed C-Rx. Newer antiviral agents, currently on trial, could show even superior results.
