Abstract
This study was conducted as a single-site, open-label, randomized, replicated crossover trial with 4 treatment periods. The aim was to evaluate the bioequivalence of a generic test drug containing velpatasvir and sofosbuvir compared to an established brand-name medication in healthy White subjects under fasting conditions. Blood samples were collected at specified intervals up to 72 hours after dosing to measure the concentrations of velpatasvir and sofosbuvir using a certified high-performance liquid chromatography with tandem mass spectrometry method. The bioequivalence of the 2 formulations was confirmed when statistical analysis showed that confidence intervals for the log-transformed peak concentration and area under the concentration-time curve from time 0 to the last quantifiable sample were within an acceptable range from 80% to 125%. Criteria for bioequivalence were met for both area under the concentration-time curve from time 0 until the last quantifiable sample and peak concentration parameters. No adverse effects were reported during this trial in both groups.

PLoS One 2021; 16:e0252274. [PMID: 34086708 PMCID: PMC8177501 DOI: 10.1371/journal.pone.0252274] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 05/14/2021] [Indexed: 12/30/2022] Open
Abstract
Background & aims We evaluated the effectiveness of sofosbuvir/velpatasvir (SOF/VEL) in difficult-to-treat PWIDs with presumed high risk for non-adherence to antiviral therapy using an innovative concept involving their opioid agonist therapy (OAT) facility. Methods N = 221 patients (m/f: 168/53; median age: 44.7 years (IQR 16.9); HCV-genotype 3: 45.2%; cirrhosis: 33.9%) treated with SOF/VEL were included. PWIDs at high risk for non-adherence to DAA therapy (n = 122) received HCV treatment alongside OAT under the supervision of medical staff ("directly observed therapy", DOT). These patients were compared to patients with presumed excellent drug compliance, who were treated in a "standard setting" (SS) of SOF/VEL prescription at a tertiary care center (n = 99). Results DOT-patients (n = 122/221; 55.2%) were younger than SS-patients (median age: 41.3 vs. 53.0 years), all had psychiatric comorbidities and most had a poor socioeconomic status. 83/122 (68.0%) reported ongoing intravenous drug use. Within the DOT-group, SVR12 was achieved in 99.1% (95% CI: 95.0–100; n = 109/110) with one patient experiencing treatment failure, while n = 12/122 (9.8%) patients were excluded due to loss of follow-up (FU). 5 patients showed HCV reinfection after achieving SVR12. SS-patients achieved SVR in 96.6% (95% CI: 90.3–99.3%; n = 84/87) after exclusion of 10/99 (10.1%) patients who were lost to FU and 2 patients who died prior to SVR12 due to reasons not related to DAA therapy. Conclusions SOF/VEL given as DOT along with OAT in PWIDs at high risk of non-adherence to antiviral therapy including those with ongoing intravenous drug use resulted in excellent SVR rates similar to patients with presumed “excellent compliance” under standard drug intake.

Nonalcoholic Steatohepatitis Is the Most Rapidly Increasing Indication for Liver Transplantation in the United States. Clin Gastroenterol Hepatol 2021; 19:580-589.e5. [PMID: 32531342 DOI: 10.1016/j.cgh.2020.05.064] [Citation(s) in RCA: 252] [Impact Index Per Article: 84.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 05/12/2020] [Accepted: 05/29/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS The profile of chronic liver disease (CLD) in the United States has changed due to obesity trends and advances in treatment of viral hepatitis. We assessed liver transplant listing trends by CLD etiology. METHODS Adult candidates for liver transplantation were selected from the Scientific Registry of Transplant Recipients (2002 through 2019). We calculated proportion trends for common CLD etiologies at time of placement on the wait list, including chronic infection with hepatitis B virus, chronic infection with hepatitis C virus (HCV), nonalcoholic steatohepatitis (NASH, including cryptogenic cirrhosis), alcohol-related liver disease (ALD) without or with chronic HCV infection, autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis, in patients with and without hepatocellular carcinoma (HCC). RESULTS From the 168,441 patients with known etiology and non-acute liver failure on the liver transplant waitlist, 27,799 patients (16.5%) had HCC. In 2002, the most common etiologies in patients without HCC were chronic HCV infection (37%) and ALD (16%), whereas only 5% had NASH. Among patients with HCC, 58% had chronic HCV infection and 10% had ALD and only 1% had NASH. In 2019, among patients without HCC, NASH was the second leading indication for liver transplantation (28% of patients), after ALD (38% of patients). Among patients with HCC, chronic HCV infection remained the leading indication (40% of patients) but NASH (24% of patients) surpassed ALD (16% of patients) to become the second leading indication. NASH was the leading indication in women without HCC (34%), in patients older than 54 years (36%), and in patients on Medicare (41%). In trend analysis, NASH was the most rapidly increasing indication for liver transplantation in patients without HCC (Kendall tau=0.97; P < .001) and in patients with HCC (tau=0.94; P < .0001). CONCLUSIONS In an analysis of data from the Scientific Registry of Transplant Recipients (2002 through 2019), we found NASH to be the second most common indication for liver transplant in 2019, and the fastest increasing indication. In 2019, NASH was the leading indication for liver transplantation among women without HCC.

Abstract
AIM The objective was to study the long-term (lifetime) cost effectiveness of four different hepatitis C virus (HCV) treatment models of care (MOC) with directly acting antiviral drugs. METHODS A cohort Markov model-based probabilistic cost-effectiveness analysis (CEA) was undertaken extrapolating to up to 30 years from cost and outcome data collected from a primary study involving a real-life Australian cohort. In this study, noncirrhotic patients treated for HCV from 1 March 2016 to 28 February 2017 at four major public hospitals and liaising sites in South Australia were studied retrospectively. The MOC were classified depending on the person providing patient workup, treatment and monitoring into MOC1 (specialist), MOC2 (mixed specialist and hepatitis nurse), MOC3 (hepatitis nurse) and MOC4 (general practitioner, GP). Incremental costs were estimated from the Medicare perspective. Incremental outcomes were estimated based on the quality-adjusted life years (QALY) gained by achieving a sustained virological response. A cost-effectiveness threshold of Australian dollar 50 000 per QALY gained, the implicit criterion used for assessing the cost-effectiveness of new pharmaceuticals and medical services in Australia was assumed. Net monetary benefit (NMB) estimates based on this threshold were calculated. RESULTS A total of 1373 patients, 64% males, mean age 50 (SD ±11) years, were studied. In the CEA, MOC4 and MOC2 clearly dominated MOC1 over 30 years with lower costs and higher QALYs. Similarly, NMB was the highest in MOC4, followed by MOC2. CONCLUSION Decentralized care using GP and mixed consultant nurse models were cost-effective ways of promoting HCV treatment uptake in the setting of unrestricted access to new antivirals.

A new model to predict response to direct-acting antiviral therapy in decompensated cirrhotics due to hepatitis C virus. Clin Exp Hepatol 2020; 6:253-262. [PMID: 33145432 PMCID: PMC7592091 DOI: 10.5114/ceh.2020.99525] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Accepted: 06/19/2020] [Indexed: 02/06/2023] Open
Abstract
AIM of the study: Decompensated hepatitis C virus (HCV) cirrhosis is a difficult to treat cohort, and there is no gold standard predictor of response to direct-acting antiviral (DAA) therapy. We conducted this study to look for factors responsible for improvement in post-therapy status, i.e. attainment of Child-Turcotte-Pugh (CTP) class A from B or C, and devise a new model to predict post-therapy response. MATERIAL and methods: Prospective analysis of data from decompensated HCV cirrhotics was done and association of each parameter with patient outcomes at 36 weeks after treatment was assessed. RESULTS 34 patients (54.8%) attained CTP class A after treatment. Factors that were independently associated with disease outcome included albumin (odds ratio [OR] = 4.84, 95% confidence interval [CI]: 1.43-20.15, p = 0.018), alanine transaminase (ALT) (OR = 1.02, 95% CI: 1-1.04, p = 0.049), bilirubin (OR = 0.41, 95% CI: 0.2-0.75, p = 0.007) and estimated glomerular filtration rate (eGFR) (OR = 1.03, 95% CI: 1.0-1.06, p = 0.045). On multivariate analysis, bilirubin was significantly associated with treatment outcome (OR = 0.28, 95% CI: 0.1-0.64, p = 0.006). A composite model was devised using demographic, biochemical, and clinical features, which has sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 67.86%, 79.41%, 73.08%, 75%, and 73.63% respectively in predicting response to therapy. Only 7.6% of patients with a Model for End-Stage Liver Disease (MELD) score > 15 and none of the patients with CTP class C met the primary end-point of our study. CONCLUSIONS 55% of our cohort met the primary end-point at 36 weeks. Patients with CTP class C and a MELD score > 15 should be referred for liver transplantation followed by DAA therapy. Our model was good at predicting improvement in post-therapy liver function.

Lymphovascular invasion on explant is associated with presenting tumor characteristics and not direct acting antiviral utilization in hepatitis C candidates undergoing liver transplantation. Clin Exp Hepatol 2019; 5:279-284. [PMID: 31893238 PMCID: PMC6935850 DOI: 10.5114/ceh.2019.88105] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Accepted: 06/16/2019] [Indexed: 12/11/2022] Open
Abstract
Aim of the study Utilization of direct acting antiviral (DAA) therapy in candidates with well-compensated hepatitis C virus (HCV) cirrhosis and hepatocellular carcinoma (HCC) accruing end stage liver disease (MELD) exception points is highly variable among transplant centers based on center location, local organ procurement dynamics, HCV(+) organ availability, and patient preference. The association between DAA utilization prior to transplant and incidence of lymphovascular invasion on explant is unknown. Material and methods Retrospective evaluation from 2013-2017 of patients on a liver transplant (LT) waitlist with HCV-related cirrhosis, MELD-Na < 15, and HCC (within T2/Milan criteria). The cohort was divided into the pre-LT DAA treated group and untreated group with clinical/viral demographics collected. Tumor presenting characteristics, locoregional treatments, wait time to LT, dropout rates and explant pathology were compared. Results DAAs were used in 44 patients prior to LT (SVR12 of 37/44 [84%]) and 19 left untreated with LT performed in 81% (51/63) of the waitlisted cohort. No significant differences were found between groups with regards to clinical/viral demographics, local-regional therapy (LRT) sessions, or frequency of lymphovascular invasion on explant. The untreated cohort had a higher rate of dropout (6.3% vs. 3.2%) (p = 0.041). On subgroup analysis of 51 subjects undergoing LT, AFP > 250 ng/ml (p = 0.003) and multifocal HCC (> 1 lesion) (p = 0.006) were associated with lymphovascular invasion on explant while DAA therapy was not (p = 0.578). Conclusions DAA therapy for waitlist active HCV candidates accruing MELD exception points has no deleterious effects on bridging LRT, nor is it associated with increased frequency of lymphovascular invasion on explant. The latter appears driven by tumor related characteristics (AFP and number of lesions) irrespective of DAA utilization prior to LT.

Transplantation of HCV Viremic Livers into HCV Viremic Recipients Followed by Direct-acting Antiviral Therapy. J Clin Transl Hepatol 2019; 7:122-126. [PMID: 31293911 PMCID: PMC6609846 DOI: 10.14218/jcth.2019.00014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 04/26/2019] [Accepted: 05/15/2019] [Indexed: 12/19/2022] Open
Abstract
Background and Aims: Hepatitis C virus (HCV)-infected organs are underutilized. We aimed to assess the safety and efficacy of direct-acting antiviral agents (DAAs) therapy in HCV viremic patients who are transplanted with a liver from a HCV viremic donor. Methods: We conducted a retrospective study, including patients seen from July 2015 to April 2017. HCV viremic patients transplanted with a liver from a HCV viremic donor and subsequently treated with DAAs were included. Outcomes assessed included undetectable viral load at 12 weeks after completing DAA therapy (sustained virologic response, SVR12), adverse events, and interactions with immunosuppression. Results: Twenty-four HCV viremic recipients received livers from HCV viremic donors. Median age was 63 years, and the majority (79.2%) were genotype 1a. Donors and recipients were viremic at the time of transplant. Median modified model for end-stage liver disease score was 19, and median time on the waitlist was 81 days. Median time from transplant to initiation of DAA therapy was 123 days. Several DAA regimens were used and 15 (62.5%) patients did not receive ribavirin. Treatment duration ranged from 12 to 24 weeks. Twenty-three (95.8%) patients achieved SVR12. Five (20.8%) patients developed adverse events; however, none required DAA discontinuation. Conclusions: DAA therapy was efficacious and well tolerated in HCV viremic recipients who underwent liver transplantation from a HCV viremic donor.

Abstract
PURPOSE OF REVIEW To highlight the current data for treatment of hepatitis C virus (HCV) in patients with hepatocellular carcinoma (HCC) awaiting orthotopic liver transplant and incorporation of various factors to decide the optimal time to initiate HCV therapy. RECENT FINDINGS Viral eradication on the waiting list has been found to lead to significant clinical improvement in approximately 20% of HCV-positive patients. However, there have been concerns raised for direct-acting antiviral (DAA) therapy in patients listed with HCC. DAA therapy leading to rapid HCV clearance has been reported to be associated with an increased risk of HCC recurrence, especially when DAA therapy is initiated in close proximity to HCC therapy. Additionally, the presence of viable HCC may significantly lower the chances of achieving sustained virologic response. Lastly, sustained virologic response can decrease the organ pool in HCV-positive waitlisted patients. SUMMARY The decision to treat HCV in patients listed for HCC pre vs. postliver transplant will require additional research.

Abstract
The Immune Tolerance Network ITN030ST A-WISH assessed immunosuppression withdrawal in liver transplant recipients with hepatitis C or nonimmune nonviral liver disease. Of 275 recipients enrolled before transplantation, 95 were randomly assigned 4:1 to withdrawal (n = 77) or maintenance (n = 18) 1- to 2-years posttransplant. Randomization eligibility criteria included stable immunosuppression monotherapy; adequate liver and kidney function; ≤Stage 2 Ishak fibrosis; and absence of rejection on biopsy. Immunosuppression withdrawal followed an 8-step reduction algorithm with ≥8 weeks per level. Fifty-two of 77 subjects (67.5%) reduced to ≤50% of baseline dose, and 10 of 77 (13.0%) discontinued all immunosuppression for ≥1 year. Acute rejection and/or abnormal liver tests were treated with increased immunosuppression; 5 of 32 rejection episodes required a methylprednisolone bolus. The composite end point (death or graft loss; grade 4 secondary malignancy or opportunistic infection; Ishak stage ≥3; or >25% decrease in glomerular filtration rate within 24 months of randomization) occurred in 12 of 66 (18%) and 4 of 13 (31%) subjects in the withdrawal and maintenance groups. Early immunosuppression minimization is feasible in selected liver recipients, while complete withdrawal is successful in only a small proportion. The composite end point comparison was inconclusive for noninferiority of the withdrawal to the maintenance group.

PNPLA3 gene predicts clinical recovery after sustained virological response in decompensated hepatitis C cirrhosis. BMJ Open Gastroenterol 2019; 6:e000241.

Abstract
Background Patients with decompensated hepatitis C virus (HCV) cirrhosis experience various outcomes after sustained virological response (SVR), ranging from clinical recovery to further deterioration. We hypothesised that the genetic risk for steatosis, namely the polymorphisms rs738409 of Patatin-like Phospholipase Domain-Containing 3 (PNPLA3), rs58542926 of Transmembrane-6-Superfamily-2 (TM6SF2), and rs641738 of Membrane-bound O-acyltransferase Domain-Containing 7 (MBOAT7), is predictive of recovery. Methods We prospectively enrolled 56 patients with Child-Pugh (CPT) B/C cirrhosis who underwent antiviral therapy. The primary outcome was change in CPT score at 12, 24, and 48 weeks after SVR. We used a linear mixed-effects model for analysis. Results Forty-five patients (PNPLA3: 21 CC, 19 CG, 5 GG) survived to the first endpoint without liver transplantation. The mean change in CPT score at 12, 24, and 48 weeks was −1.57 (SE=0.30), –1.76 (SE=0.32), and −2.0 (SE=0.36), respectively, among the patients with the PNPLA3 CC genotype and −0.50 (SE=0.20), –0.41 (SE=0.25), and −0.24 (SE=0.27), respectively, among the other 24 patients. After adjustment for baseline characteristics, the PNPLA3 CG/GG genotypes were associated with a 1.29 (SE=0.30, p<0.0001) point higher CPT score. Most of the difference came from differences in hepatic encephalopathy and bilirubin. The results for rs58542926 and rs641738 were not significant. Conclusion The PNPLA3 CG/GG genotypes could identify a subgroup of patients with decompensated HCV cirrhosis that had suboptimal clinical recovery despite SVR. An understanding of the genetic factors that influence clinical outcomes will help target patients for liver transplant based on individual genetic risk factors and provide insight leading to new therapeutic approaches.

Abstract
This commentary reviews the core principals of cost-effectiveness and applies them to the rapidly evolving context of hepatitis C virus treatment in the United States. The article provides a foundation of evidence that hepatitis C virus treatment provides good economic value, even though it is expensive, and even when treating people who inject drugs who are at high risk for hepatitis C virus reinfection. The price of medications has decreased, but the high price continues to limit access to care. This wedge between cost effectiveness and affordability stands front and center as one of the leading obstacles to elimination.

The impact of direct-acting antiviral agents on liver and kidney transplant costs and outcomes. Am J Transplant 2018; 18:2473-2482. [PMID: 29701909 PMCID: PMC6409105 DOI: 10.1111/ajt.14895] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2018] [Revised: 04/14/2018] [Accepted: 04/17/2018] [Indexed: 02/06/2023]
Abstract
Direct-acting antiviral medications (DAAs) have revolutionized care for hepatitis C positive (HCV+) liver (LT) and kidney (KT) transplant recipients. Scientific Registry of Transplant Recipients registry data were integrated with national pharmaceutical claims (2007-2016) to identify HCV treatments before January 2014 (pre-DAA) and after (post-DAA), stratified by donor (D) and recipient (R) serostatus and payer. Pre-DAA, 18% of HCV+ LT recipients were treated within 3 years and without differences by donor serostatus or payer. Post-DAA, only 6% of D-/R+ recipients, 19.8% of D+/R+ recipients with public insurance, and 11.3% with private insurance were treated within 3 years (P < .0001). LT recipients treated for HCV pre-DAA experienced higher rates of graft loss (adjusted hazard ratio [aHR] 1.34 1.852.10 , P < .0001) and death (aHR 1.47 1.681.91 , P < .0001). Post-DAA, HCV treatment was not associated with death (aHR 0.34 0.671.32 , P = .25) or graft failure (aHR 0.32 0.641.26 , P = .20) in D+R+ LT recipients. Treatment increased in D+R+ KT recipients (5.5% pre-DAA vs 12.9% post-DAA), but did not differ by payer status. DAAs reduced the risk of death after D+/R+ KT by 57% (0.19 0.430.95 , P = .04) and graft loss by 46% (0.27 0.541.07 , P = .08). HCV treatment with DAAs appears to improve HCV+ LT and KT outcomes; however, access to these medications appears limited in both LT and KT recipients.

Elimination of Hepatitis C in Liver Transplant Recipients. J Clin Transl Hepatol 2018; 6:247-250. [PMID: 30271735 PMCID: PMC6160303 DOI: 10.14218/jcth.2017.00079] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2017] [Revised: 02/20/2018] [Accepted: 02/26/2018] [Indexed: 12/11/2022] Open
Abstract
Background and Aims: Recurrent hepatitis C (HCV) disease in liver transplant (LT) recipients is associated with significant morbidity and mortality. With the availability of noninterferon-based therapy, eliminating HCV may be achievable in LT recipients. Methods: We studied all consecutive recipients who underwent LT at the University of California Los Angeles between January 2005 and June 2017. We collected data on date of transplant and last follow-up, as well as laboratory values. We also recorded type and timing of antiviral therapy relative to LT. Analyses were performed to assess the proportion of LT recipients who are viremic after transplant. Results: Six hundred thirty-four patients underwent LT with a diagnosis of HCV. There was a statistically significant trend for patients to be cured before (p < 0.001) and after liver transplantation (p < 0.001) for the study period of 2014 to 2016 relative to 2005 and 2013, respectively. Of the 634 recipients eligible for therapy, 8% and 74% were treated within 12 months of transplant for the study periods 2005 to 2013 and 2014 to 2016, respectively. There was a significant decrease between the two study periods in the proportion of patients undergoing re-LT 1 year after the original LT: 5.5% (n = 28/510) and 1.5% (n = 2/124) respectively for study periods 2005 to 2013 and 2014 to 2016 respectively (p = 0.011). Conclusions: The proportion of LT recipients who are viremic has decreased over time. Eliminating HCV in LT recipients is feasible after the introduction of direct-acting agents. Curing HCV should translate to improved clinical outcomes in LT recipients who were transplanted for HCV infection with longer follow-up. Preliminary results suggest the decreased need for transplant in the direct-acting agents era.

Abstract
Different strategies of DAAs treatment are currently possible both pre- and postliver transplantation (LT). Clinical and economic consequences of these strategies still need to be adequately investigated; this study aims at assessing their cost-effectiveness. A decision analytical model was created to simulate the progression of HCV-infected patients listed for decompensated cirrhosis (DCC) or for hepatocellular carcinoma (HCC). Three DAAs treatment strategies were compared: (i) a 12-week course of DAAs prior to transplantation (PRE-LT), (ii) a 4-week course of DAAs starting at the time of transplantation (PERI-LT) and (iii) a 12-week course of DAAs administered at disease recurrence (POST-LT). The population was substratified according to HCC presence and, in those without HCC, according to the MELD score at listing. Data on DAAs effectiveness were estimated using a cohort of patients still followed by 11 transplant centres of the European Liver and Intestine Transplant Association and by data available in the literature. In this study, PRE-LT treatment strategy was dominant for DCC patients with MELD<16 and cost-effective for those with MELD16-20, while POST-LT strategy emerged as cost-effective for DCC patients with MELD>20 and for those with HCC. Sensitivity analyses confirmed PRE-LT as the cost-effective strategy for patients with MELD≤20. In conclusion, PRE-LT treatment is cost-effective for patients with MELD≤20 without HCC, while treatments after LT are cost-effective in cirrhotic patients with MELD>20 and in those with HCC. It is worth reminding, though, that the final choice of a specific regimen at the patient level will have to be personalized based on clinical, social and transplant-related factors.

Abstract
INTRODUCTION Hepatitis C negatively changes patient quality of life even in the absence of advanced liver disease. The specific patterns of quality of life of hepatitis C positive patients waiting for transplant or after surgery are not widely studied. Areas covered: A significant percentage of infected patients show cognitive impairment, fatigue, and/or a 'brain fog', that cannot be explained by the liver disease. Depression can be diagnosed in one third of hepatitis C positive patients. Conflicting data are available regarding the possible role of Model for End-Stage Liver Disease score as predictor of impaired quality of life. In the first period after liver transplant, quality of life tends to increase at the pre-transplant period but in the medium and long-term period, it declines. The recurrence of hepatitis C infection represents a strong predictor of morbidity and mortality and can significantly affect the global quality of life of patients. Expert commentary: Hepatologists, surgeons and psychologists should collaborate to support infected patients in all phases of transplant including the long-term period after surgery. Education and information should be implemented especially regarding the positive role of new direct antivirals.

Abstract
PURPOSE OF REVIEW This review examines the issues in determining the decision to treat a HCV-positive patient who is a liver transplant (LT) candidate with highly effective and well-tolerated direct-acting antiviral (DAA) therapies. RECENT FINDINGS Cure of HCV with DAA can improve liver function and allow delisting in some patients. Beyond a threshold of hepatic impairment (likely MELD score > 16 to 20), patients may experience a decline in MELD score with HCV cure without improvement in liver-related complications resulting in decreased opportunity to receive a LT. Eradicating HCV from patients who need LT regardless also deprives them of the option of receiving HCV-positive donor organs. Patients with MELD > 16 or Child-Pugh B/C may also have reduced cure rates of HCV, increased risk of hepatic decompensation, and adverse events with DAA pre-LT compared to post-LT DAA therapy. Preliminary data demonstrates increase risk of hepatocellular carcinoma (HCC) recurrence after treatment with DAA with subsequent studies raising doubts about this association. Patients with HCV cirrhosis on the LT waiting list with MELD score > 16, CTP-B/C, and HCC are best treated after LT with better response, tolerability, and the ability to receive organs from a larger donor pool that includes HCV-positive donors. Larger, prospective studies are needed to assess whether increased HCC recurrence after DAA is a true effect.

Abstract
BACKGROUND & AIMS Oral direct-acting antivirals (DAAs) for hepatitis C virus (HCV) treatment offer new hope to both pre- and post-liver transplant (LT) patients. However, whether to treat HCV patients before vs after LT is not clear because treatment can improve liver function but could reduce the chance of receiving an LT while on the waiting list. Our objective was to evaluate the cost effectiveness of pre-LT vs post-LT HCV treatment with oral DAAs in decompensated cirrhotic patients on the LT waiting list. METHODS We used a validated mathematical model that simulated a virtual trial comparing long-term clinical and cost outcomes of pre-LT vs post-LT HCV treatment with oral DAAs. Model parameters were estimated from United Network for Organ Sharing data, SOLAR-1 and 2 trials, and published studies. For each strategy, we estimated the quality-adjusted life-year, life expectancy, cost, and the incremental cost-effectiveness ratio. RESULTS For lower MELD scores, quality-adjusted life-years were higher with pre-LT HCV treatment compared with post-LT treatment. Pre-LT HCV treatment was cost saving in patients with MELD scores of 15 or less, and cost effective in patients with MELD scores of 16 to 21. In contrast, post-LT HCV treatment was cost effective in patients with MELD scores of 22 to 29 and cost saving if MELD scores were 30 or higher. Results varied by drug prices and by United Network for Organ Sharing regions. CONCLUSIONS For cirrhotic patients awaiting LT, pre-LT HCV treatment with DAAs is cost effective/saving in patients with MELD scores of 21 or lower, whereas post-LT HCV treatment is cost effective/saving in patients with MELD scores of 22 or higher.

Abstract
OBJECTIVES Hepatitis C genotype 6 (HCV-GT6) is one of the most prevalent genotypes in Southeast Asia. Ledipasvir and sofosbuvir fixed-dose combination (LDV/SOF FDC) for 12 weeks has been shown to be effective for multiple HCV genotypes including treatment-naïve HCV-6. Our goal was to examine treatment outcomes in a diverse HCV-6 population. METHODS We prospectively enrolled 60 HCV-GT6 patients at four US centers. Treatment -naïve without cirrhosis patients received open-labeled LDV/SOF FDC orally once a day for 8 weeks; All cirrhotic and/or treatment-experienced patients received LDV/SOF FDC for 12 weeks. The primary outcome was sustained virological response 12 weeks after therapy (SVR12). Secondary outcomes were adverse events (AEs) and/or serious adverse events (SAEs). All patients gave written consent. RESULTS Overall mean age was 58±10 and 58% were male. All patients were Asian and foreign born. The 8-week group included 20 patients (33.3%) and the 12-week included 40 patients (66.7%). There were 2 (5%) patients with decompensation, 3 with liver cancer (7.5%), and 14 with prior treatment (35%) in the 12-week group. SVR12 was 95.0% for the 8-week group (19/20) and 95.0% for the 12-week group (38/40). AEs included fatigue (5%), insomnia (3.3%), headache (1.7%), and nausea (1.7%); however, all patients completed the intended treatment duration. There were two treatment-unrelated SAEs. CONCLUSIONS LDV/SOF FDC for 8 or 12 weeks was safe and effective for patients without cirrhosis or prior treatment failure as well as for patients with cirrhosis and/or prior treatment failure, respectively.

METHODS We conducted a systematic search of various electronic databases, including Medline, EMBASE, Cochrane library and EconLit for cost-effectiveness studies published from 2011 to 2016. Studies evaluating DAAs for genotypes 2-6 were included. Reported costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs) were abstracted. We re-estimated ICERs by varying the price of DAAs from $20 000 to $100 000, and estimated the threshold price at which DAA regimens would be deemed cost-effective (ICER≤$100 000/QALY). RESULTS A total of 92 ICERs for 7 different DAA regimens from 10 published articles were included. Among the abstracted 92 ICERs, 20 were for genotype 2, 40 for genotype 3, 30 for genotype 4, 2 for genotype 5 and none for genotype 6; therefore, only genotypes 2-5 were analysed. At the discounted price of $40 000, 87.0% analyses found DAA regiments to be cost-effective, and 7.6% found to be cost-saving. The median threshold price below which DAAs would be deemed cost-effective was between $144 400 and $225 000, and cost-saving between $17 300 and $25 400. CONCLUSIONS HCV treatment with DAAs is highly cost-effective in patients with HCV genotypes 2-5 at a $100 000/QALY threshold. Timely HCV treatment would be an optimal strategy from both a public health and economic perspective.
