31%, p = 0.003). As for IL28B SNPs, there were no significant differences in viral response until week 12 in SMV, while IL28B gene variation was identified as a significant predictive factor for SVR in TVR by multiple logistic-regression analysis (OR = 12.0, p = 0.029). Drug adherence of TVR this website (OR = 16.1, p<0.0001) and PEG-IFN (OR = 11.8, p<0.0001) were also associated with SVR in TVR treatment, and it was suggested that more than 60% of TVR and 80% of PEG-IFN were needed for achieving SVR for difficult-to-treat patients such as null responders of prior treatment or non rapid viral responders.

Adherence of RBV became significant in SMV treatment, because adherence of SMV were 100% in 95% of the participants. Before treatment, RAVs against NS3 and NS5A inhibitors were detected in 3% and 17% of the patients by direct sequencing, and 45% and 87% by deep sequencing, respectively. SVR rates in TVR were not different between patients with and without RAVs of NS3 (79% and 91%, respectively, p = 0.362), and those of NS5A (86% and 76%, p = 0.443), and viral clearance rates of patients with RAVs of NS3 and/or NS5A were equal. However, in patients unresponsive to IFN who

had NS5A RAVs before treatment, failure of TVR or SMV treatment resulted in development of multi-drug CCI-779 in vivo resistant variants. Conclusion: IFN-based DAAs regimens achieve high SVR rates regardless of presence of RAVs at baseline as much as good adherence has maintained. In contrast, failure of the treatments in patients with NS5A RAVs at baseline MCE lead to a risk for development of multi-drug resistant variant, which may hamper next generation IFN-free regimens with DAAs.

As compared to those with normal renal function, the AUC0-inf of SOF is 2.7-fold higher in patients with severe renal impairment, and the AUC0-inf of GS-331007, the renally excreted major SOF metabolite, is 5.5-fold higher. This study investigates the safety, efficacy and PK of SOF+RBV in HCV-infected patients with severe renal impairment. Methods: In an open-label study, 10 patients with chronic HCV GT1 or 3 with creatinine clearance (CrCl) less than 30mL/min as calculated by the Cockcroft-Gault equation, not on dialysis, are being treated with SOF 200mg + RBV 200mg daily for 24 wks.

1, 5 The finding of unchanged hepatic homocysteine concentrations among

groups is most likely due to its conversion to SAH through the reverse SAH hydrolase reaction. Others who used the same wild-type C56Bl6J mouse showed marked elevation of plasma homocysteine after intragastric ethanol feeding but did not measure liver levels,6, 27 whereas we previously found four-fold elevation of selleck compound plasma homocysteine but only modest increase in liver levels in chronic ethanol fed micropigs.1 The concentration disparity is likely due to the fact that homocysteine undergoes continuous rapid metabolism in the liver, whereas plasma homocysteine is not metabolized and represents the cumulative export of homocysteine from liver and other tissues.28 The metabolic regulation of homocysteine in the liver would predictably cause elevated liver

SAH in the Het-E group as a result of the dual inhibitory effects of ethanol on transmethylation of homocysteine to methionine and of CβS deficiency on reducing homocysteine excretion through the transsulfuration pathway.4 The correlation between the decreased SAM/SAH ratio of methylation capacity and the worsening histopathology and apoptosis in the present model strengthens evidence that aberrant methionine metabolism contributes to the pathogenesis of ASH. In evaluating mechanisms for development of ASH through altered methionine metabolism in our model, we found that ethanol, genotype, and their interaction increased the induction of ER stress pathways of lipogenesis GDC-0068 supplier and apoptosis. These pathways included enhanced expression of ER chaperone GRP78 and lipogenic transcription factor SREBP 1-c, as well as apoptosis mediators ATF4, ATF6, GADD153, and caspase-12 (Table 2, Fig. 2). These findings extend other observations on ER stress from the intragastric ethanol-fed mouse.6, 27 Furthermore, the findings on the MCE公司 relationships of altered SAM/SAH ratio and ER stress-induced lipogenesis and apoptosis can explain the effects of the different diets on the histopathology and TUNEL scores

shown in Table 1 and Fig. 1. In addition to ER stress, the increased response of SREBP-1c mRNA expression to ethanol feeding (Table 2) may also reflect the additional contribution of the adiponectin signaling pathway of lipogenesis, as described in ethanol-fed micropigs7 and in C57BL6 mice fed oral ethanol diets.29 However, the effect of intragastric infusion of a high ethanol diet on the adiponectin signaling pathway of steatosis is not known. The enhanced SREBP-1c expression in the Het-E group (Table 2) is consistent with our prior finding of its correlation with elevated SAH levels in the ethanol-fed micropig.5 The observed discordance of mRNA and protein levels of SREBP-1c in the Het-E group (Table 2, Fig. 2F) may reflect instability and enhanced protein degradation of SREBP-1c.

However, the role of FAK in HCC remains elusive. Studying Neratinib the role of FAK in hepatocar-cinogenesis by in vivo models is critical to determine whether it is involved in the pathogenesis of HCC and whether it is a suitable candidate target for treating HCC. Methods:

In this study, we generated mice with hepatocyte-specific deletion of FAK

and investigated the role of FAK in an oncogenic (c-MET/β-cat-enin, MET/CAT)-driven liver carcinogenesis model. Results: Fak deficiency in hepatocytes significantly decreased tumor proliferation and HCC development. Importantly, deletion of FAK prolonged survival of animals with MET/CAT-induced HCC. Furthermore, FAK was activated by c-MET but not β-catenin, in mouse livers and HCC cell lines. Finally, we demonstrated that FAK mediates activation of AKT and ERK by c-MET in mouse livers and HCC cell lines. Conclusion: FAK is required for c-Met/β-catenin-driven hepatocarcinogenesis. selleck chemical Inhibition of FAK may be a promising strategy to treat HCC. Disclosures: The following people have nothing to disclose: Na Shang, Maribel Arteaga, Jimmy Stauffer, Scott Cotler, Jiwang Zhang, Wei Qiu Aim: PPARβ/δ is a member of the nuclear receptor family involved in the regulation of various cellular functions. However, the role of PPARβ/δ in carcinogenesis

remains controversial. We aimed to examine the biological functions and related molecular mechanisms of PPARβ/δ in hepatocellular carcinoma (HCC). Methods and materials: The expression profiles of PPARβ/δ were detected in 108 pairs human 上海皓元 liver cancer, non-tumor tissue and 12 liver cancer cell lines by real-time PCR. HepG2 HCC cells were transfected with GV230-PPARβ/δ, while PPARβ/δ were knockdown by lenovirus GV113-shRNA in Huh7 cells. The effect of PPARβ/δ on cells malignant transformation were determined by viability assay, colony formation, cell cycle analyses, wound healing assay and Matrigel invasive model in vitro, along with in vivo tumorigenicity assays. The PPARβ/δ target signal pathway was identified by DNA microarray and chromosome immunoprecipitation (ChIP). Results: The mean expression level of PPARβ/δ was significantly lower in primary HCCs as compared to their adjacent normal tissues (P=0.0153). In vitro analyses showed that PPARβ/δ was critical in HCC cell lines to suppress cell proliferation, migration and invation, induce apoptosis, arrest cell cycle at G2/M phase as well as inhibit tumor growth in nude mice (P <0.001).

34 However, as we demonstrated by EMSA and ChIP assays (Fig. 5), it is BMS354825 also recognized by KLF15. It is possible that KLF15 and Sp1 work synergistically to modulate gene transcription as has been documented.24 Finally, mutations in the putative KLF15-binding site in the core promoter reduced HBV DNA copy numbers in mouse sera, indicating the importance of this KLF15 site in

HBV gene expression and replication (Fig. 8). KLF factors regulate various important cellular functions, including differentiation, apoptosis, cell proliferation, and metabolism.19 KLF15 activates the expression of genes involved in glucose metabolism and adipogenesis, including the insulin-sensitive glucose transporter, GLUT4, and peroxisome proliferator-activated receptor gamma.22, 35 It is expressed Selleckchem Talazoparib in multiple tissues, including the liver.25 Hepatic expression of KLF15 is increased upon fasting and decreased upon feeding.36 Interestingly, Shaul et al. have shown, in a mouse model, that food deprivation induces the expression of HBV genes, which is reversible upon refeeding.37

Perhaps, part of the HBV activation observed by Shaul et al. is attributable to the fasting-induced activation of KLF15. KLF15−/− mice are viable and show hypoglycemia only upon fasting.23 Therefore, inhibition of KLF15 should be amenable as a potential HBV therapeutic modality. We thank Drs. P.J. Chen, Y. Shaul, and S. Gray for plasmids. This article is dedicated to Dr. T.S. Benedict Yen, who was an inspiring mentor.

“Sustained virologic suppression is a primary goal of therapy for chronic hepatitis B (CHB). In study entecavir (ETV)-022, 48 weeks of entecavir 0.5 mg was superior to lamivudine for virologic suppression for hepatitis B e antigen (HBeAg)-positive CHB. A total of 183 entecavir-treated patients from ETV-022 subsequently enrolled

in study ETV-901. We present the results after up to 5 years (240 weeks) of continuous entecavir therapy. The entecavir long-term cohort consists of patients who received ≥1 medchemexpress year of entecavir 0.5 mg in ETV-022 and then entered ETV-901 with a treatment gap ≤35 days. In ETV-901 the entecavir dose was 1.0 mg daily. For patients with samples available at Year 5, proportions with hepatitis B virus (HBV) DNA <300 copies/mL, normal alanine aminotransferase (ALT) levels, HBeAg loss, and HBeAg seroconversion were determined. In all, 146 patients met criteria for inclusion in the entecavir long-term cohort. At Year 5, 94% (88/94) had HBV DNA <300 copies/mL and 80% (78/98) had normal ALT levels. In addition to patients who achieved serologic responses during study ETV-022, 23% (33/141) achieved HBeAg seroconversion and 1.4% (2/145) lost hepatitis B surface antigen (HBsAg) during study ETV-901. Through 5 years, entecavir resistance emerged in one patient. The safety profile of entecavir was consistent with previous reports.

6 This discrepancy may, in part, be explained by the use of different cell lines. Indeed, we have failed to establish cellular alcoholic steatosis models in two hepatoma cell Selleckchem CH5424802 lines (H4IIEC3 and McA-RH7777). On the other hand, though lipin-1

and SREBP-1 are both targets of ethanol, the underlying mechanisms for the observed effects could be entirely different between them. Interestingly, we and several other groups have recently shown that both acetaldehyde and acetate, two major metabolites of ethanol, are involved in alcoholic liver injury.18, 19 Our current findings suggest that ethanol increased lipin-1 gene expression largely through activation of SREBP-1 and NF-Y. Conceivably, additional molecular mechanisms are also involved. For instance, several putative glucocorticoid

(GC) response elements (GREs) in the LPIN1 promoter selleck screening library have been identified. Indeed, lipin-1 expression is directly regulated by GCs in liver and adipose tissue.20, 21 This effect requires the GR and is mediated by binding of the receptor to GRE sites upstream of the LPIN1 gene. The GC-mediated effects are specific to lipin-1 (i.e., not lipin-2 or -3). The involvement of GC in ethanol-induced increases in lipin-1 is supported by a previous study showing that ethanol-mediated PAP activity was attenuated in adrenalectomized rats.10 Surprisingly, we found that the in vivo association of acetylated

histone H3/Lys9 or GR with the Lpin1-GRE site in response to ethanol exposure was not significantly induced. We recently demonstrated that lipin-1 exhibits reciprocal patterns of gene expression in livers and adipose tissues of chronically ethanol-fed mice, suggesting a mechanism largely independent of GC effects.13 The definitive involvement of GCs in ethanol-mediated up-regulation of lipin-1 may need to be further studied through use of genetically modified animal models—such as liver-specific GR knockout mice. MCE公司 It is also tempting to speculate that ethanol may stabilize lipin-1 protein via enhanced lipin-1 acetyaltion and, subsequently, inhibition of lipin-1 degradation. The molecular role of lipin-1 is dependant upon its subcellular localization. Nuclear compartmentalization of lipin-1 ensures that its role as a transcriptional coactivator predominates over its role as a PAP enzyme.1-5 Sumoylation of lipin-1α is required for its nuclear localization and transcriptional coactivator activity toward PGC-1α in cultured neuronal cells.5 Our current in vivo findings show that ethanol feeding markedly reduced hepatic lipin-1 sumoylation levels, which correlates with the observed dramatic reduction in its nuclear localization. In addition to inhibition of lipin-1 sumoylation, ethanol feeding also robustly increased the acetylation of lipin-1 in mouse livers.

6D). We also measured the mRNA levels of GSTP1 and CDH1 by real-time PCR in HepG2 cells after transfection. The GSTP1 mRNA expression level was significantly decreased in the miR-152 inhibitor group compared with the control group (Fig. 6B). This indicated that the inhibition of miR-152 could decrease GSTP1 expression by promoter DNA hypermethylation. However, the CDH1 mRNA level was not significantly changed after transfection, probably because

the increase in the DNA methylation level was not sufficient to inhibit the mRNA expression. Epigenetic dysregulation of cellular genes is an integral R428 solubility dmso feature in the development of human cancers. Increasing evidence has revealed that viral genes are some of the key players in regulating DNA methylation.33 The epigenetic mechanisms

involved in virus-associated cancers are poorly understood, although aberrant promoter hypermethylation is a prevalent phenomenon in human cancers closely associated with viruses, such as HBV-related HCC. Hypermethylation is responsible for the silencing of TSGs involved in hepatocarcinogenesis. The involvement of the HBx protein in epigenetic regulation during hepatocarcinogenesis has been demonstrated previously, and it involves the activation of DNMTs7, 34 and the recruitment of DNMTs and methyl-CpG binding proteins to the target gene promoters. Interestingly, a strong correlation between HBV infection and epigenetic alterations of TSGs, including cyclin-dependent kinase inhibitor 2A (p16INK4a),35, 36 insulin-like DAPT cell line growth factor binding protein 3,7 GSTP1,37 E-cadherin (CDH1),36, 38 and Ras association domain family 1A (RASSF1A),36 has been shown. However, how HBV affects the DNA methylation states remains unknown. In this study, we characterized the role of miR-152 in the regulation of DNA methylation in HBV-related HCC for the first time. miR-152 induced aberrant DNA methylation by directly targeting DNMT1. Our data showed that miR-152 was frequently down-regulated 上海皓元 in HBV-positive HCCs in comparison with corresponding noncancerous liver tissues. This indicated

that miR-152 may have a tumor-suppressive role in HCC development. Our findings indicated that miR-152 expression was inversely correlated with DNMT1 expression in HCC; the down-regulation of miR-152, resulting in an up-regulation of DNMT1, was significant in HCC development. DNMT1 has been reported to be necessary and sufficient for maintaining global methylation and aberrant CpG island methylation in human cancer cells.39 Transcriptional silencing by CpG island methylation is a prevalent mechanism of TSG suppression in cancers. It is well known that decitabine, a potent and specific hypomethylating agent and an inhibitor of the DNMT activity that mediates DNA methylation, has been approved by the US Food and Drug Administration to treat myelodysplastic syndromes. Decitabine is also being studied in the treatment of cancer.

After being washed with PBS, cells were incubated with 0.5% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with PBS, containing 5% bovine serum albumin, for 60 minutes at 37°C. Cells were subsequently GS-1101 mouse incubated with anti-SMO antiserum (H-300, 1:250; Santa Cruz Biotechnology, Santa Cruz, CA) at 4°C overnight. After being washed, coverslips were incubated with Texas Red-X goat antirabbit immunoglobulin G (T6391, 1:1,000; Invitrogen, Carlsbad, CA) for 1 hour in the dark. Cells were then washed three times in PBS,

one time in water, and mounted using Prolong Antifade (Invitrogen). The slides were analyzed by fluorescent confocal microscopy (LSM 510; Carl Zeiss, Jena, Germany). In additional experiments, SMO trafficking was examined by total internal reflection fluorescence (TIRF) microscopy.31 KMCH-1 cells cultured on coverslips were transfected with GFP-SMO

plasmid 48 hours before study. Cells were treated as indicated and Selleck EX-527 fixed with ddH2O, containing 2.5% formaldehyde, 0.1 M of piperazine-N,N′-bis(2-ethanesulfonic acid), 1.0 mM of ethylene glycol tetraacetic acid, and 3.0 mM of MgSO4 for 20 minutes at 37°C. Cells were then washed three times in PBS, one time in water, and mounted using Prolong Antifade (Invitrogen). Slides were analyzed with a TIRF microscope (AxioObserver.Z1; Carl Zeiss). GFP-SMO localized to the plasma membrane was quantified using image analysis software (AxioVision 4.8.2.0; Carl Zeiss). Data are expressed as the average fluorescence intensity in the cell multiplied by the number of pixels above the background. To determine GLI activity, a reporter containing eight directly repeated copies of a consensus GLI-binding site (8×-GLI) downstream of the luciferase gene was employed (pδ51LucII plasmid; δ-crystalline promoter).32 The 8×-GLI reporter was kindly provided by M. Fernandez-Zapico (Division of Oncology Research, Mayo Clinic, Rochester, MN). The MCE plasmid

was transfected into normal, stable scrambled, or short-hairpin RNA targeting SMO (shSMO) KMCH-1 cells (0.5 μg/well), using FuGene HD (Roche Diagnosis, Basel, Switzerland). Cells were cotransfected with 50 ng of a plasmid expressing Renilla luciferase under the control of cytomegalovirus (pRL-CMV; Promega, Madison, WI). Twenty-four hours after transfection, cells were treated as indicated, cell lysates were prepared, and both firefly and Renilla luciferase activities were quantified using the Dual-Luciferase Reporter Assay System (Promega), according to the manufacturer’s instructions. Firefly luciferase activity was normalized to Renilla luciferase activity to control for transfection efficiency and cell numbers. Data (firefly/Renilla luciferase activity) are expressed as fold increase over vehicle-treated cells transfected with the 8×-GLI/pRL-CMV reporter constructs. All animal studies were performed in accord with and approved by the institutional animal care and use committee.

Disadvantages include a high degree of operator dependency and inability to access the central surfaces of the joints of maximal interest in people with haemophilia. Standardized protocols for ultrasound assessment of ankles, knees and elbows have been published [19-21]. Recently, Martinoli and colleagues have reported details of a simplified ultrasound Sunitinib scanning protocol and scoring system for

use in people with haemophilia, the Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) [22]. Studies of ankles, knees and elbows for 49 subjects with haemophilia yielded good to excellent inter- and intra-observer reliability with this scoring system. Although promising, the HEAD-US method requires validation against physical examination, radiography and MRI in a larger series of individuals with haemophilia. The Haemophilia Activities List (HAL) is a patient-reported questionnaire developed by Dutch investigators that can be used as part of a test battery to evaluate the functional health status of adults with haemophilia. The investigators recommended that both a disease-specific activity measure (e.g. the HAL) and a performance test should be included BI 6727 mouse when assessing the functional health status of people with haemophilia [23]. The developmental studies of the HAL were conducted in adults with

haemophilia, most of whom had the severe form of the disorder [23, 24]. The investigators were careful to emphasize that additional studies in children <18 years of age and in adults with moderate/mild haemophilia A are required to determine if the current version of the HAL requires modification for use in these patient populations. A paediatric version of the HAL (pedHAL) has been developed and is being evaluated. The Functional Independence Score in Haemophilia (FISH) 上海皓元 is an objective, performance-based assessment tool developed by investigators at the Christian Medical College, Vellore, India to assess the functional ability of adults with haemophilia [25, 26]. When used by trained healthcare personnel

the current version of the tool has excellent measurement properties [26, 27]. A modification in the FISH, suitable for use in children with haemophilia treated with prophylaxis, is in development. There has been much debate over the definitions of activities and participation. The ICF (Fig. 1) defines activities as ‘the execution of a task or action by an individual’ while participation encompasses ‘involvement in a life situation’. As an example, running may be an activity a young boy with haemophilia can perform, whereas choosing to run with his friends in a soccer game would be an example of participation. Here, again the inclusion of disease-specific and generic measures is recommended. Several disease-specific measures are described below. Disease-specific QoL instruments with good measurement properties (i.e.

38 In that study, CS exposure was associated with increased ALT. Future studies are needed to better elucidate the mechanistic aspects of the effects of CS in NAFLD and to better characterize the Nutlin-3 cell line role of CS in human NAFLD. Nonetheless, this study provides one more reminder that there is already ample experimental

and clinical evidence consistently pointing in the same direction: CS aggravates liver injury in CLD. It is time to take the harmful effects of CS in CLD more seriously. As hepatologists, we need to incorporate the intake of a more thorough smoking history during our evaluations, educate our patients on the effects of this modifiable risk factor on liver injury, and strongly recommend smoking cessation Small molecule library research buy in all patients with CLD. “
“Dominant negative form of transforming growth factor beta receptor type II (dnTGFβRII) mice, expressing a dominant negative form of TGFβ receptor II under control of the CD4 promoter, develop autoimmune colitis and cholangitis. Deficiency in interleukin (IL)-12p40

lead to a marked diminution of inflammation in both the colon and the liver. To distinguish whether IL-12p40 mediates protection by the IL-12 or IL-23 pathways, we generated an IL-23p19−/− dnTGFβRII strain deficient in IL-23, but not in IL-12; mice were longitudinally followed for changes in the natural history of disease and immune responses. Interestingly, IL-23p19−/− mice demonstrate dramatic improvement in their colitis, but no changes in biliary pathology; mice also manifest reduced T-helper (Th)17 cell populations and unchanged IFN-γ levels. We submit that the IL-12/Th1 pathway is essential for biliary disease pathogenesis, whereas the IL-23/Th17 pathway mediates colitis. To further assess the mechanism

of the IL-23-mediated protection from colitis, we generated an IL-17A−/− dnTGFβRII strain deficient in IL-17, a major effector cytokine produced by IL-23-dependent Th17 cells. Deletion of the IL-17A gene did not affect the severity of either cholangitis or colitis, suggesting 上海皓元 that the IL-23/Th17 pathway contributes to colon disease in an IL-17-independent manner. These results affirm that the IL-12/Th1 pathway is critical to biliary pathology in dnTGFβRII mice, whereas colitis is caused by a direct effect of IL-23. (HEPATOLOGY 2012) Murine strains with a deficiency in specific cytokine pathways are important tools for investigating the mechanism of immunopathogenesis of autoimmunity. Mice transgenic for directed expression of a dominant negative form of transforming growth factor beta receptor type II (dnTGFβRII), under the control of the CD4 promoter lacking the CD8 silencer, spontaneously develop an inflammatory bowel disease (IBD).

On

average patients completed 11 weeks of therapy at the time of data analysis. None of the pts died while on therapy, one patient (5%) on ribavirin discontinued all treatment due to AKI and severe anemia and one patient who was listed LY294002 in vitro for chronic rejection received re-transplantation while on therapy and his HCV RNA remained negative after transplant. In the SOF+SMV group median (IQR) creatinine levels were significantly worse at week 8 of therapy compared to BL(1.00 (0.95-1.5) to 1.7 (1.05, 1.95)), p=0.026.There was a trend towards an increase in tacrolimus level in this group (4.5 (3.9, 4.85) at baseline to 5.5 (4.1 to 6.45) on week 4), p = 0.066. There was no decline in hemoglobin level in the SOF + SMV group at weeks 4 or 8. In the SOF + RBV group, there was no effect on creatinine or TAC levels. All patients had undetectable HCV RNA with normalization of ALT/AST at week 4(Median ALT 56 to 19 and AST 78 to 22, p=0.008). Conclusion: In our experience, SOF-based regimens

were safe and effective in treating HCV recurrence. The combination of SOF+SMV was associated with an increase in creatinine levels and a mild increase in TAC levels which requires further Dabrafenib research buy monitoring. Disclosures: John J.

Sciences The following people have nothing to disclose: Mohammed Eyad Yaseen Alsab-bagh, Ibrahim A. Hanouneh, Binu V. John, John K. Guirguis, Bijan Eghtesad, Nizar N. Zein Background: Non-interferon based therapy for chronic hepatitis C genotype 1 is a global goal. To date, there is limited data on the use of an all-oral treatment regimen in the post-liver transplant population. Methods: Thirty seven patients transplanted for genotype 1 chronic HCV were treated using an off-label combination of sofosbuvir, simeprevir, +/− ribavirin for 12 weeks. We collected data on patient characteristics, viral response, laboratory MCE values, and adverse events. The decision to treat patients for recurrent HCV post-transplant was made by one of 6 transplant hepatologists. Patients were monitored with monthly clinic visits and lab testing every 2-4 weeks during treatment. Results: Twenty five patients had genotype 1a, 7 patients had genotype 1b, and 5 patients were undifferen-tiated. There were 27 males (73%) and 14 African Americans (38%). The average age was 57 years (range 32-69) and the average time from transplant was 4 years (range 4-334 months). Twenty patients (54%) were treatment-experienced. Eight patients (22%) had recurrent cirrhosis. Sixteen patients (43%) were treated with ribavirin;13 started ribavirin at onset of treatment and 3 had ribavirin added due to slow viral response.
