RESUMO

BACKGROUND: Direct-acting antiviral (DAA) agents for the treatment of hepatitis C virus (HCV) infection have been proven safe and effective in cirrhotic patients awaiting liver transplantation (LT). However, in the long term, data remain minimal regarding the clinical impact of viral eradication on patients listed for decompensated cirrhosis or hepatocellular carcinoma (HCC). We aimed to elucidate the clinical outcomes of patients regarding delisting and the evolution of HCC during the long-term follow-up. METHODS: An observational, multicenter, retrospective analysis was carried out on prospectively collected data from HCV-positive patients treated with an interferon-free regimen while awaiting LT in 18 French hospitals. RESULTS: A total of 179 patients were included in the study. The indication for LT was HCC in 104 (58.1%) patients and cirrhosis in 75 (41.9%) patients. The sustained virological response was 84.4% and the treatment was well tolerated. At five years, among 75 patients with cirrhosis treated for HCV, 19 (25.3%) were delisted following improvement after treatment. Predictive factors for delisting highlighted an absence of ascites, MELD score ≤ 15, and Child-Pugh score ≤ 7. No patients with refractory ascites were delisted. Among patients with HCC, 82 (78.9%) were transplanted. The drop-out rate was low (6.7%) and few recurrences of HCC after LT were observed. CONCLUSIONS: DAAs are safe and effective in patients awaiting LT for cirrhosis or HCC. A quarter of patients with cirrhosis can be delisted because of clinical improvement. Predictive factors for delisting, as a result of improvement, may assist prescribers, before initiating HCV infection therapy in the long-term perspective.

RESUMO

PURPOSE: Direct-acting antiviral agents have demonstrated their efficacy in treating HCV recurrence after liver transplantation and particularly the sofosbuvir/daclatasvir combination. Pharmacokinetic data on both calcineurin inhibitors and direct-acting antiviral exposure in liver transplant recipients remain sparse. METHODS: Patients were enrolled from the ANRS CO23 CUPILT cohort. All patients treated with sofosbuvir/daclatasvir with or without ribavirin were included in this study when blood samples were available to estimate the clearance of immunosuppressive therapy before direct-acting antiviral initiation and during follow-up. Apparent tacrolimus and cyclosporine clearances were estimated from trough concentrations measured using validated quality control assays. RESULTS: Sixty-seven mainly male patients (79%) were included, with a mean age of 57 years and mean MELD score of 8.2; 50 were on tacrolimus, 17 on cyclosporine. Ribavirin was combined with sofosbuvir/daclatasvir in 52% of patients. Cyclosporine clearance remained unchanged as well as tacrolimus clearance under the ribavirin-free regimen. Tacrolimus clearance increased 4 weeks after direct-acting antivirals and ribavirin initiation versus baseline (geometric mean ratio 1.81; 90% CI 1.30-2.52). Patients under ribavirin had a significantly higher fibrosis stage (> 2) (p = 0.02) and lower haemoglobin during direct-acting antiviral treatment (p = 0.02) which impacted tacrolimus measurements. Direct-acting antiviral exposure was within the expected range. CONCLUSION: Our study demonstrated that liver transplant patients with a recurrence of hepatitis C who are initiating ribavirin combined with a sofosbuvir-daclatasvir direct-acting antiviral regimen may be at risk of lower tacrolimus concentrations because of probable ribavirin-induced anaemia and higher fibrosis score, although there are no effects on cyclosporine levels. TRIAL REGISTRATION: NCT01944527.

RESUMO

Sofosbuvir (SOF) combined with nonstructural protein 5A (NS5A) inhibitors has demonstrated its efficacy in treating a recurrence of hepatitis C virus (HCV) after liver transplantation (LT). However, the duration of treatment and need for ribavirin (RBV) remain unclear in this population. Our aim was to determine whether LT recipients could be treated with an SOF + NS5A inhibitor-based regimen without RBV for 12 weeks post-LT. Between October 2013 and December 2015, 699 LT recipients experiencing an HCV recurrence were enrolled in the multicenter ANRS CO23 CUPILT cohort. We selected patients receiving SOF and NS5A inhibitor ± RBV and followed for at least 12 weeks after treatment discontinuation. The primary efficacy endpoint was a sustained virological response 12 weeks after the end of treatment (SVR12). Among these 699 patients, 512 fulfilled the inclusion criteria. Their main characteristics were: 70.1% genotype 1, 18.2% genotype 3, 21.1% cirrhosis, and 34.4% previously treated patients. We identified four groups of patients according to their treatment and duration: SOF + NS5A without RBV for 12 (156 patients) or 24 (239 patients) weeks; SOF + NS5A + RBV for 12 (47 patients) or 24 (70 patients) weeks. SVR12 values reached 94.9%, 97.9%, 95.7%, and 92.9%, respectively (P = 0.14). Only 20 patients experienced a treatment failure. Under multivariate analysis, factors such as fibrosis stage, previous treatment, HCV genotype, and baseline HCV viral load did not influence SVR12 rates in the four groups (P = 0.21). Hematological adverse events (AEs) were more common in the RBV group: anemia (P < 0.0001) and blood transfusion (P = 0.0001). CONCLUSION: SOF + NS5A inhibitors without RBV for 12 weeks constituted reliable therapy for recurrent HCV post-LT with an excellent SVR12 whatever the fibrosis stage, HCV genotype, and previous HCV treatment.

RESUMO

BACKGROUND: A recurrence of hepatitis C virus (HCV) after liver transplantation affects survival in human immunodeficiency virus (HIV)/HCV coinfected patients. This study assessed the efficacy and safety of sofosbuvir (SOF)-based regimens in HIV/HCV coinfected patients after liver transplantation. METHODS: Twenty-nine HIV/HCV coinfected transplanted patients receiving tacrolimus-, cyclosporine-, or everolimus-based immunosuppressive therapy were enrolled in the Compassionate Use of Protease Inhibitors in Viral C Liver Transplantation cohort. Their antiviral treatment combined SOF, daclatasvir with or without ribavirin (n = 10/n = 6), or SOF, ledipasvir with or without ribavirin (n = 2/n = 11). RESULTS: The median delay between liver transplantation and treatment initiation was 37.5 months (interquartile range [IQR], 14.4-99.2). The breakdown of HCV genotypes was G1, 22 patients (75.9%); G3, 3 patients (10.3%); and G4, 4 patients (13.8%). The treatment indications were HCV recurrence (≥ F1 n = 23) or fibrosing cholestatic hepatitis (n = 6). Before starting SOF, the HCV viral load and CD4 count were 6.7 log10 IU/mL (IQR, 5.9-7.2) and 342 cells/mm (IQR, 172-483), respectively. At week 4, the HCV viral load was less than 15 IU/mL in 12 (42.9%) patients. The overall sustained virological response 12 was 96.6%. No significant drug-drug interactions were observed. CONCLUSIONS: SOF-based treatment regimens produced excellent results in HIV/HCV coinfected patients after liver transplantation, suggesting an important change in their prognosis.

RESUMO

Hepatitis C virus (HCV) infection is associated with reduced patient survival following combined liver-kidney transplantation (LKT). The aim of this study was to assess the efficacy and safety of second-generation direct-acting antivirals (DAAs) in this difficult-to-treat population. The ANRS CO23 "Compassionate use of Protease Inhibitors in Viral C Liver Transplantation" (CUPILT) study is a prospective cohort including transplant recipients with recurrent HCV infection treated with DAAs. The present work focused on recipients with recurrent infection following LKT. The study population included 23 patients. All patients received at least one NS5B inhibitor (sofosbuvir) in their antiviral regimen an average of 90 months after LKT. Ninety-six percent of recipients achieved a sustained virological response (SVR) at week 12 (SVR12). In terms of tolerance, 39% of recipients presented with at least one serious adverse event. None of the patients experienced acute rejection during therapy and there were no deaths during follow-up. The glomerular filtration rate (GFR) decreased significantly from baseline to the end of therapy. However, this study did not show that the decline in GFR persisted over time or that it was directly related to DAAs. The DAA-based regimen is well tolerated with excellent results in terms of efficacy. It will become the gold standard for the treatment of recurrent HCV following LKT.

RESUMO

BACKGROUND & AIMS: Optimally effective treatment for hepatitis C virus genotype 3 (GT3) is urgently needed, particularly in advanced liver disease. Daclatasvir plus sofosbuvir was efficacious in phase 3 studies. Real-world data for daclatasvir+sofosbuvir in advanced GT3 infection are presented from the French Temporary Authorisation for Use programme, which allowed patients in need without other treatment options access to daclatasvir ahead of its market authorization. METHODS: Patients with F3/F4 fibrosis and/or extrahepatic hepatitis C virus manifestations, post-liver transplant hepatitis C virus recurrence and/or indication for liver/kidney transplant, were treated with daclatasvir+sofosbuvir (60+400 mg daily) for a recommended duration of 24 weeks. Addition of ribavirin and/or shorter treatment was at physician's discretion. The primary efficacy analysis was sustained virological response at post-treatment week 12 (SVR12; modified intention-to-treat). Safety was assessed by spontaneous adverse event reporting. RESULTS: The efficacy population comprised 333 patients, mostly cirrhotic (77%, of whom 18% were decompensated) and treatment experienced (72%). After 24 weeks of daclatasvir+sofosbuvir, SVR12 was 89% (174/196) overall (95% CI 83.6-92.5%), 98% (43/44) without cirrhosis (95% CI 88.2-99.6%) and 86% (129/150) with any degree of cirrhosis (95% CI 79.5-90.7%), without SVR12 increase in those who received additional ribavirin for 24 weeks (SVR12 82% [50/61; 95% CI 70.5-89.6%]). Among 516 GT3-infected patients with safety data, 5 discontinued for adverse events and 11 died. CONCLUSIONS: Daclatasvir+sofosbuvir achieved high SVR12 rates and was well tolerated in this large real-world cohort of GT3-infected patients with advanced liver disease, without benefit of ribavirin in those treated 24 weeks.

RESUMO

BACKGROUND AND AIMS: In this French multicentre, open-label study, we analyzed the efficacy, safety and patient-reported outcomes of a boceprevir-based triple therapy in HCV genotype 1 cirrhotic patients awaiting liver transplantation (LT). METHODS: Patients received PEG-IFN/ribavirin (RBV) for 48 weeks (W) and boceprevir from W4 to W48 or until LT. RESULTS: Fifty-one patients (80% males, median age: 56 years) were included. Fifty-seven percent had hepatocellular carcinoma and 43% end-stage liver disease. At enrolment, the median MELD score was 9 (range: 6-18); the Child-Pugh score was A in 65%, B in 35% and C in 2%. Therapy was discontinued because of severe adverse events (SAEs) in 39% of cases and virological inefficacy in 24%. 16% of patients had undetectable HCV RNA 24 weeks after the end of treatment (SVR24). LT was performed in 18 patients (35%). HCV RNA was undetectable in 16.6% at LT. Seven patients (14%) died and three deaths were attributed to treatment. SAEs (n=129) were observed in 84% of patients. Twenty-four percent of patients developed severe infections. Albumin<35g/L was independently associated with severe infection. Compared with baseline values, a significant decrease (P=0.02) of the physical dimension of health-related quality of life was observed between W4 and W24. The mean (95% CI) number of self-reported symptoms doubled during treatment (from 6.3 [4.8-7.7] to 11.8 [9.3-14.3]; P<0.001). CONCLUSIONS: The safety of the PEG-IFN/RBV/boceprevir combination is poor in patients awaiting LT, with a high risk of severe infection. Moreover, the limited efficacy confirms the indication for IFN-free combinations in these patients.

RESUMO

We report a case of sustained remission of a liver transplant patient infected with hepatitis C virus (HCV) genotype 1 undergoing hemodialysis treatment. Oral treatment regimen of the HCV infection consists of a combination of sofosbuvir 400 mg after each hemodialysis session and daclatasvir 60 mg daily, for a period of 3 months. Laboratory testing indicate that the combination regimen was well-tolerated with no sign of drug-drug interaction. Confirmation of these clinical observations in large clinical studies may help improve morbidity and decrease mortality outcome in patients infected with HCV and undergoing hemodialysis treatment.

RESUMO

Recurrence of hepatitis C virus (HCV) after liver transplantation (LT) can rapidly lead to liver graft cirrhosis and, therefore, graft failure and retransplantation or death. The aim of the present study was to assess efficacy and tolerance of sofosbuvir (SOF)-based regimens for the treatment of HCV recurrence in patients with severe fibrosis after LT. The Compassionate Use of Protease Inhibitors in Viral C Liver Transplantation (CULPIT) study is a prospective multicenter cohort including patients with HCV recurrence following LT treated with second generation direct antivirals. The present study focused on patients included between October 2013 and November 2014 and diagnosed with HCV recurrence and liver graft extensive fibrosis (METAVIR F3/F4). A SOF-based regimen was administered to 125 patients fulfilling inclusion criteria. The median delay from LT was 95.9 ± 69.6 months. The characteristics of patients were as follows: mean age, 59.4 ± 9.0 years; 78.4% male; infected by HCV genotype 1: 78.2%, mean HCV RNA: 6.1 ± 1.0 log10 IU/mL. Eighty patients had failed previous post-LT antiviral therapy (64.0%) including triple therapy with first generation protease inhibitors in 19 (15.2%) patients. The main combination regimen was SOF/daclatasvir (73.6%). Ribavirin was used in 60 patients. Sustained virological response 12 weeks after treatment was 92.8% (on an intention-to-treat basis); 7 patients with virological failure were observed. Serious adverse events occurred in 25.6% of the patients during antiviral treatment. During antiviral treatment and follow-up, 3 patients were retransplanted and 4 patients died. In conclusion, SOF-based antiviral treatment shows very promising results in patients with HCV recurrence and severe fibrosis after LT. Liver Transplantation 22 1367-1378 2016 AASLD.

RESUMO

BACKGROUND & AIMS: HCV recurrence remains a major issue in the liver transplant field, as it has a negative impact on both graft and patient survival. The purpose of this study was to investigate the efficacy and safety of treating HCV recurrence with sofosbuvir (SOF) and daclatasvir (DCV) combination therapy. METHODS: From October 2013 to March 2015, 559 liver recipients were enrolled in the prospective multicentre France REcherche Nord&Sud Sida-hiv Hépatites (ANRS) Compassionate use of Protease Inhibitors in viral C Liver Transplantation cohort. We selected 137 patients with an HCV recurrence receiving SOF and DCV, whatever the genotype or fibrosis stage. The use of ribavirin and the duration of therapy were at the investigator's discretion. The primary efficacy end point was a sustained virological response (SVR) 12weeks after the end of treatment. RESULTS: The SVR rate 12weeks after completing treatment was 96% under the intention-to treat analysis and 99% when excluding non-virological failures. Only two patients experienced a virological failure. The serious adverse event (SAE) rate reached 17.5%. Four patients (3%) stopped their treatment prematurely because of SAEs. Anaemia was the most common AE, with significantly more cases in the ribavirin group (56% vs. 18%; p<0.0001). A slight but significant reduction in creatinine clearance was reported. No clinically relevant drug-drug interactions were noted, but 52% of patients required a change to the dosage of immunosuppressive drugs. CONCLUSIONS: Treatment with SOF plus DCV was associated with a high SVR12 and low rates of serious adverse events among liver recipients with HCV recurrence. LAY SUMMARY: The recurrence of hepatitis C used to be the first cause of graft failure in infected liver transplanted recipients. Our study demonstrates the great efficacy of one combination of new all-oral direct-acting antiviral, sofosbuvir and daclatasvir, to treat the recurrence of hepatitis C on the graft. Ninety-six per cent of recipients were cured. The safety profile of this combination seemed to be good, especially no relevant drug-drug interaction with immunosuppressive drugs.

RESUMO

BACKGROUND AND AIMS: First generation protease inhibitors (PI) with peg-interferon (PEG-IFN) and ribavirin (RBV) have been the only therapy available for hepatitis C virus (HCV) genotype 1 infection in most countries for 3 years. We have investigated the efficacy and tolerance of this triple therapy in transplanted patients experiencing a recurrence of HCV infection on the liver graft. PATIENTS: This cohort study enrolled 81 liver transplant patients (Male: 76%, mean age: 55.8±9.7 years) with severe HCV recurrence (F3 or F4: n = 34 (42%), treatment experienced: n = 44 (54%)), treated with boceprevir (n = 36; 44%) or telaprevir (n = 45; 56%). We assessed the percentages of patients with sustained virological responses 24 weeks after therapy (SVR24), and safety. RESULTS: The SVR24 rate was 47% (telaprevir: 42%; boceprevir: 53%, P = ns). At baseline, a normal bilirubin level (p = 0.0145) and albumin level >35g/L (p = 0.0372) and an initial RBV dosage of ≥800 mg/day (p = 0.0033) predicted SVR24. During treatment, achieving an early virological response after 12 weeks was the strongest independent factor to predict SVR24 (p<0.0001). A premature discontinuation of anti-HCV therapy due to a serious adverse event (SAE) was observed in 22 patients (27%). Hematological toxicity, infections and deaths were observed in 95%, 28% and 7% of patients, respectively. A history of post-LT antiviral therapy and thrombocytopenia (<50G/L) during treatment were both independent predictors of the occurrence of infections or SAE (p = 0.0169 and p = 0.011). CONCLUSIONS: The use of first generation PI after liver transplantation enabled an SVR24 rate of 47% in genotype 1 patients, but induced a high rate of SAE. The identification of predictive factors for a response to treatment, and the occurrence of SAE, have enabled us to establish limits for the use of this anti-HCV therapy in the transplant setting.

RESUMO

Fibrosing cholestatic hepatitis is a severe form of post-liver transplantation HCV recurrence. Fibrosing cholestatic hepatitis is characterized by its early onset and severe prognosis in HIV-infected patients. We report the case of an HIV-HCV genotype-4 coinfected patient successfully treated with a combination of sofosbuvir and ribavirin. After 4 weeks of treatment we observed a resolution of HCV recurrence related symptoms associated with a normalization of liver biochemistry and dramatic decrease of HCV viral load. This case illustrates the efficiency and tolerance of a sofosbuvir-based anti-HCV interferon-free regimen in post-liver HCV recurrence. Because of the absence of drug interactions between sofosbuvir and antiretroviral treatment or calcineurin inhibitors, its administration in HIV-HCV-coinfected liver transplanted patients is very promising.

RESUMO

BACKGROUND: Conflicting data exist regarding the risk for hepatocellular carcinoma after transjugular intrahepatic porto-systemic shunt (TIPS) insertion in cirrhotic patients. METHODS: We retrospectively analysed histopathological data from 214 patients who were transplanted in our Institution including 68 patients who underwent TIPS placement before transplantation. Pathological lesions from explanted livers, including incidental hepatocellular carcinoma, small cell dysplasia and large cell dysplasia were recorded. RESULTS: Pathological lesions were found in 36.4% of explanted livers. TIPS insertion was an independent risk factor for pathological lesion (HR = 2.11, p < 0.05), concurrently with age (HR = 1.10 per year, p < 0.001) and viral aetiology of cirrhosis (HR = 3.05, p < 0.001). When considering the different type of lesions, TIPS insertion was not associated with an increased risk for hepatocellular carcinoma but was an independent risk factor for liver dysplasia (HR = 2.15, p = 0.042). CONCLUSION: Although a direct relationship between TIPS insertion and hepatocellular carcinoma risk was not demonstrated in this study, the increased frequency of liver dysplasia observed in TIPS-bearing explanted livers deserves further prospective investigations with adequate follow-up.

RESUMO

Telaprevir and boceprevir, the two first hepatitis C virus (HCV) NS3 protease inhibitors (PIs), considerably increase rates of sustained virologic response in association with pegylated interferon and ribavirin in chronic HCV genotype 1 infections. The 30 first patients treated by telaprevir or boceprevir including anti-HCV therapies since 2011 in Marseille University hospitals, France, were monitored. HCV loads and plasmatic concentrations of telaprevir and boceprevir were determined on sequential blood samples. HCV NS3 protease gene population sequencing was performed at baseline of treatment and in case of treatment failure. Fifteen patients (including 7 co-infected with HIV) received telaprevir and the other 15 patients (including 4 co-infected with HIV) received boceprevir. At baseline, HCV NS3 protease from six patients harbored amino acid substitutions associated with PI-resistance. Treatment failure occurred at week 12 for 7 patients. Amino acid substitutions associated with PI-resistance were observed in six of these cases. HCV NS3 R155K and T54A/S mutants, all of genotype 1a, were found from four patients. Median (interquartile range) plasma concentrations were 3,092 ng/ml (2,320-3,525) for telaprevir and 486 ng/ml (265-619) for boceprevir. For HIV-HCV co-infected patients, median concentrations were 3,162 ng/ml (2,270-4,232) for telaprevir and 374 ng/ml (229-519) for boceprevir. Plasma drug concentration monitoring revealed undetectable concentrations for two patients at week 4, and probable non-adherence to therapy for another patient. These findings indicate that routine HCV NS3 protease sequencing and plasma PI concentration monitoring might be helpful to characterize cases of therapy failure, at a cost dramatically low compared to that of anti-HCV therapy.

RESUMO

Hepatitis E virus of genotype 3 (HEV-3) is an emerging cause of sporadic autochthonous acute hepatitis in Europe. Although spontaneous outcome of hepatitis E is usually favorable, fulminant liver failure has been described worldwide. In Europe, autochthonous hepatitis E associated with fulminant hepatic failure and leading to liver transplantation has been exceptionally reported. We report here four cases of fulminant and sub-fulminant hepatitis E proposed for liver transplantation in Marseille University hospitals between July 2006 and March 2010. HEV diagnosis relied on detection of anti-HEV IgM antibodies and HEV RNA in serum samples. All cases were men, with no travel history in hyperendemic areas. HEV sequence analyses revealed genotype 3 HEV in the four patients. Liver histology indicated severe acute hepatitis in all of them, pre-existing fibrosis being found in two cases. Two patients underwent liver transplantation, and the two other patients could not be transplanted due to septic complications and died. HEV testing should be performed for the initial evaluation of every acute liver failure regardless of the epidemiological and clinical context. With respect to the potentially fulminant evolution of HEV genotype 3 infections, treatment with ribavirin of severe acute hepatitis E should be considered.

RESUMO

BACKGROUND: The purpose of this study was to assess the impact of transjugular intrahepatic portosystemic shunting (TIPS) on liver transplantation (LT). METHODS: Seventy-two patients transplanted after TIPS insertion between 1996 and 2008 were compared with 136 matched patients transplanted without prior TIPS. RESULTS: At time of LT, 10% of the TIPS were occluded and 32% were misplaced. Shunt removal was difficult in 17% of the TIPS patients and required vena cava clamping in 10%. Collateral venous circulation was less extensive and intra-operative portocaval anastomosis was required more frequently in the TIPS group. No significant difference in transfusion requirements and operative times were observed between the two groups. Postoperatively, liver and renal function tests, in-hospital stay, graft rejection, re-transplantation and 1-year mortality rates were not statistically different. Ascites volume in the first week was greater in the TIPS group (7.6 L vs 6.9 L, P=0.036). In the TIPS group, ascites and collateral circulation were greater if the shunt was occluded at the time of LT. Shunt misplacement or occlusion was not associated with higher intra-operative or postoperative complication rates. CONCLUSION: TIPS did not impair LT and can provide a safe bridge for LT in the end-stage cirrhotic patients.
