Bhamidi-marri, Lewis W. Teperman, Gerond Lake-Bakaar, Fredric D. Gordon, Daniel Maluf Fibrosing cholestatic hepatitis (FCH) is a rare but severe form of HCV-recurrence following liver transplantation (LT) leading to poor short term survival. Therapeutic options are limited. Study aims were to assess efficacy and tolerance of sofosbuvir

(SOF) and daclatasvir (DCV)-based regimens in this setting. Methods: The CUPILT study is a prospective nationwide cohort including patients with HCV-recurrence following LT treated by new antivirals. The present work focused on 21 patients diagnosed with FCH and included between Oct 2013 and Feb 2014. FCH diagnosis was based on strict criteria including histological review by an expert pathologist. Treatment regimens were prescribed at investigator’s discretion. Patients were followed at W0, W1, W2, W3, W4, W6, W8 and W12. Results: FCH was diagnosed after a median duration of 6 months [range 1-18] following LT and therapy started at 10 months [2-38] post LT. Features of patients at W0 were: median IWR-1 cell line filipin age: 53 years [36-67], men: 81%, G1: 76%, G3: 10%, G4: 14%, ALT: 128 IU/L [46-588], gGT: 595 IU [86-5,511], bilirubin: 6.0 mg/dL [0.6-19], albumin : 3.2 g/dL [1.6-4.0], HCV RNA : 6.9 log IU/ml [4.6-8.4]. Ascites was observed in 8 (38%) patients. Four (19%) were HIV-co-infected and 14 (67%) failed

to antiviral therapy containing protease inhibitors in 9 (43%) cases. The following regimens were used: Peg-IFNa + SOF + RBV (n=2), SOF + RBV (n=6), SOF + DCV (n=1) and SOF + DCV + RBV (n=12) for 24 weeks. All patients were alive without re-transplantation at W12. HCV RNA was not detectable at W2 and W4 in 1 (5%) and 3 (14%) patients, respectively. At W12, 20 (95%) patients had HCV RNA <15 IU/ml and 17 (81%) were not detectable. Early viral kinetics was not influenced by treatment regimens. The rates of ALT and gGT normalization at W12 were 76% and 52%, respectively. Median bilirubin serum levels rapidly decreased from 6.0 to 3.6 at W1 and 2.6 mg/dL at W2. The median time to achieve bilirubin levels below 2 mg/dL was 6 weeks. At week 12, 19 (90%) of patients had bilirubin below 2 mg/dl, and 13 (69%) below 1 mg/dL. Albumin levels increased from 31 to 36 g/L at W12. This was accompanied by clinical improvement including nutritional status (weight gain from 67.5 to 70.0 Kg). Ascites disappeared in 4/8 patients, but remained stable in 2 patients who had initially refractory ascites.
