Diagnosis and management of hepatic encephalopathy: The French recommendations.

Hepatic encephalopathy (HE) is a frequent and severe complication of liver disease with poor patient outcomes. However, it is a poorly understood complication, with no consensus for diagnosis. Therefore, HE is often underdiagnosed. Differential diagnosis may be cumbersome because of non-specific symptoms, such as confusion, cognitive disorders, the aetiological factors of cirrhosis and comorbidities, which are often observed in cirrhotic patients. Therefore, an overt or covert form of HE should be systematically investigated. Advice is provided to drive patient work-up. Effective treatments are available to prevent or treat HE bouts, but the issue of single or combination therapy has not been resolved. Transjugular intrahepatic portosystemic shunt (TIPS) placement largely improved the prognosis of cirrhotic patients, but HE occurrence of HE is often a fear, even when post-TIPS HE can be avoided by a careful selection of patients and preventive treatment. HE is an indication of liver transplantation. However, its reversibility post-transplantation and the consequences of transplantation in patients with other causes of neurological disorders remain controversial, which supports the performance of an extensive work-up in expert centres for this subset of patients. The present guidelines assist clinicians in the diagnosis of the overt or covert form of HE to implement curative and preventive treatments and clarify which patients require referral to expert centres for consideration for liver transplantation. These guidelines are very clinically oriented and address different frequent clinical issues to help physicians make bedside decisions.

Economic Impact of European Liver and Intestine Transplantation Association (ELITA) Recommendations for Hepatitis B Prophylaxis After Liver Transplantation.

The European Liver and Intestine Transplant Association, ELITA, promoted a Consensus Conference involving 20 experts across the world which generated updated guidelines on HBV prophylaxis in liver transplant candidates and recipients. This study explores the economic impact associated with the implementation of the new ELITA guidelines. To this aim, a condition-specific cohort simulation model has been developed to compare new and historical prophylaxis, including only pharmaceutical cost and using the European perspective. The target population simulated in the model included both prevalent and incident cases, and consisted of 6,133 patients after the first year, that increased to 7,442 and 8,743 patents after 5 and 10 years from its implementation. The ELITA protocols allowed a cost saving of around € 235.65 million after 5 years and € 540.73 million after 10 years; which was mainly due to early HIBG withdrawal either after the first 4 weeks or after the first year post Liver Transplantation (LT) depending on the virological risk at transplantation. Results were confirmed by sensitivity analyses. The money saved by the implementation of the ELITA guidelines would allow healthcare decision makers and budget holders to understand where costs could be reduced and resources re-allocated to different needs.

Ribavirin for Hepatitis E Virus Infection After Organ Transplantation: A Large European Retrospective Multicenter Study.

BACKGROUND: Ribavirin is currently recommended for treating chronic hepatitis E virus (HEV) infection. This retrospective European multicenter study aimed to assess the sustained virological response (SVR) in a large cohort of solid organ transplant (SOT) recipients with chronic HEV infection treated with ribavirin monotherapy (N = 255), to identify the predictive factors for SVR, and to evaluate the impact of HEV RNA mutations on virological response. METHODS: Data from 255 SOT recipients with chronic HEV infection from 30 European centers were analyzed. Ribavirin was given at the median dose of 600 (range, 29-1200) mg/day (mean, 8.6 ± 3.6 mg/kg/day) for a median duration of 3 (range, 0.25-18) months. RESULTS: After a first course of ribavirin, the SVR rate was 81.2%. It increased to 89.8% when some patients were offered a second course of ribavirin. An increased lymphocyte count at the initiation of therapy was a predictive factor for SVR, while poor hematological tolerance of ribavirin requiring its dose reduction (28%) and blood transfusion (15.7%) were associated with more relapse after ribavirin cessation. Pretreatment HEV polymerase mutations and de novo mutations under ribavirin did not have a negative impact on HEV clearance. Anemia was the main adverse event. CONCLUSIONS: This large-scale retrospective study confirms that ribavirin is highly efficient for treating chronic HEV infection in SOT recipients and shows that the predominant HEV RNA polymerase mutations found in this study do not affect the rate of HEV clearance.This large-scale retrospective study that included 255 solid organ transplant recipients confirms that ribavirin is highly efficient for treating chronic hepatitis E virus (HEV) infection and shows that HEV RNA polymerase mutations do not play a role in HEV clearance.

Clinical validation of the FLIP algorithm and the SAF score in patients with non-alcoholic fatty liver disease.

BACKGROUND & AIMS: Histological classifications used to diagnose/stage non-alcoholic fatty liver disease (NAFLD) are based on morphology, with undetermined clinical correlates and relevance. We assessed the clinical relevance of the fatty liver inhibition of progression (FLIP) algorithm and the steatosis, activity, and fibrosis (SAF) scoring system. METHODS: One hundred and forty consecutive patients with suspected NAFLD and a separate validation cohort of 78 patients enrolled in a therapeutic trial, all with central reading of liver biopsy, were included. FLIP and SAF were used to categorize patients with non-alcoholic steatohepatitis (NASH), non-NASH NAFLD (NAFL), or non-NAFLD. The SAF activity score assessed hepatocyte ballooning and lobular inflammation; a histologically severe disease was defined as a SAF activity score of ≥3 and/or bridging fibrosis or cirrhosis. Clinical, biochemical, and metabolic data were analyzed in relation to histology. RESULTS: Patients with NASH according to the FLIP algorithm had a clinical profile distinct from those with NAFL, with a higher prevalence of metabolic risk factors (increased body mass index [BMI], central obesity, serum glucose, and glycated hemoglobin), more severe insulin resistance (fasting insulin and homeostasis model assessment for insulin resistance [HOMA-IR] values), and higher levels of aminotransferases. Similar findings were documented for patients with severe disease vs. those without. Positive linear trends existed between NASH or severe disease and increasing BMI and HOMA-IR. There was a strong association between liver fibrosis and NASH or SAF-defined scores of activity. Patients with either significant or bridging fibrosis overwhelmingly had NASH, and bridging fibrosis most often coexisted with severe activity. CONCLUSIONS: The FLIP algorithm/SAF score, although based on purely morphological grounds, are clinically relevant, as they identify patients with distinct clinical and biological profiles of disease severity. Disease activity in NAFLD is associated with fibrosis severity. LAY SUMMARY: The examination of liver tissue under the microscope (histology) serves to define the type and severity of non-alcoholic fatty liver disease morphologically, and is also used to determine improvement in therapeutic or natural history clinical trials. The FLIP algorithm/SAF classification is a new histological classification well validated on morphological but not clinical grounds. Here, we demonstrate that different disease categories defined by the FLIP/SAF classification correspond to entities of different clinical and biological severity. We also show a strong association between the activity of steatohepatitis (defined histologically) and the amount of fibrotic scar.

12 Weeks of a Ribavirin-Free Sofosbuvir and Nonstructural Protein 5A Inhibitor Regimen Is Enough to Treat Recurrence of Hepatitis C After Liver Transplantation.

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.

Longterm Risk of Solid Organ De Novo Malignancies After Liver Transplantation: A French National Study on 11,226 Patients.

De novo malignancies are one of the major late complications and causes of death after liver transplantation (LT). Using extensive data from the French national Agence de la Biomédecine database, the present study aimed to quantify the risk of solid organ de novo malignancies (excluding nonmelanoma skin cancers) after LT. The incidence of de novo malignancies among all LT patients between 1993 and 2012 was compared with that of the French population, standardized on age, sex, and calendar period (standardized incidence ratio; SIR). Among the 11,226 LT patients included in the study, 1200 de novo malignancies were diagnosed (10.7%). The risk of death was approximately 2 times higher in patients with de novo malignancy (48.8% versus 24.3%). The SIR for all de novo solid organ malignancies was 2.20 (95% confidence interval [CI], 2.08-2.33). The risk was higher in men (SIR = 2.23; 95% CI, 2.09-2.38) and in patients transplanted for alcoholic liver disease (ALD; SIR = 2.89; 95% CI, 2.68-3.11). The cancers with the highest excess risk were laryngeal (SIR = 7.57; 95% CI, 5.97-9.48), esophageal (SIR = 4.76; 95% CI, 3.56-6.24), lung (SIR = 2.56; 95% CI, 2.21-2.95), and lip-mouth-pharynx (SIR = 2.20; 95% CI, 1.72-2.77). In conclusion, LT recipients have an increased risk of de novo solid organ malignancies, and this is strongly related to ALD as a primary indication for LT.

Peak hyperammonemia and atypical acute liver failure: The eruption of an urea cycle disorder during hyperemesis gravidarum.

Inborn urea cycle disorders are under-recognised metabolic causes of hyperammonemia in adults. A 28-year-old primigravida, seven weeks pregnant, affected by hyperemesis gravidarum developed acute liver injury (ALI) and then acute liver failure (ALF) in less than 48 h. Because the patient developed atypical features, especially mildly elevated aminotransferases contrasting with very high blood ammonia levels (281 µmol/L), concomitant with normal serum creatinine, an inborn error of metabolism was suspected. We performed emergency metabolic analyses, stopped all protein intake and started with intravenous (i.v.) high caloric intake, nitrogen scavenger drugs and haemodialysis. The neurological and hepatic status of the patient quickly improved together with normalisation of her ammonemia levels. High plasma glutamine and urinary orotic acid, alongside low plasma arginine, citrulline and ornithine were suggestive of an ornithine transcarbamylase deficiency, later confirmed by molecular analyses. Foetal sex was female, as determined by foetal DNA analysis in maternal blood, and foetal development was unremarkable throughout the pregnancy. Delivery was induced at 39 weeks with a close monitoring of ammonemia levels and i.v. perfusion of carbohydrates and lipids during labour and immediately post-partum to avoid hypercatabolism. Delivery was uneventful and the patient delivered a healthy female baby. Urea cycle disorders should be contemplated in non-jaundiced patients with ALI or ALF, severe hyperammonemia and normal serum creatinine regardless of serum aminotransferase levels. The prompt recognition of this rare condition and the rapid initiation of adequate metabolic therapy are mandatory to prevent irreversible neurological sequelae and to avoid liver transplantation.

Ribavirin for chronic hepatitis E virus infection in transplant recipients.

BACKGROUND: There is no established therapy for hepatitis E virus (HEV) infection. The aim of this retrospective, multicenter case series was to assess the effects of ribavirin as monotherapy for solid-organ transplant recipients with prolonged HEV viremia. METHODS: We examined the records of 59 patients who had received a solid-organ transplant (37 kidney-transplant recipients, 10 liver-transplant recipients, 5 heart-transplant recipients, 5 kidney and pancreas-transplant recipients, and 2 lung-transplant recipients). Ribavirin therapy was initiated a median of 9 months (range, 1 to 82) after the diagnosis of HEV infection at a median dose of 600 mg per day (range, 29 to 1200), which was equivalent to 8.1 mg per kilogram of body weight per day (range, 0.6 to 16.3). Patients received ribavirin for a median of 3 months (range, 1 to 18); 66% of the patients received ribavirin for 3 months or less. RESULTS: All the patients had HEV viremia when ribavirin was initiated (all 54 in whom genotyping was performed had HEV genotype 3). At the end of therapy, HEV clearance was observed in 95% of the patients. A recurrence of HEV replication occurred in 10 patients after ribavirin was stopped. A sustained virologic response, defined as an undetectable serum HEV RNA level at least 6 months after cessation of ribavirin therapy, occurred in 46 of the 59 patients (78%). A sustained virologic response was also observed in 4 patients who had a recurrence and were re-treated for a longer period. A higher lymphocyte count when ribavirin therapy was initiated was associated with a greater likelihood of a sustained virologic response. Anemia was the main identified side effect and required a reduction in ribavirin dose in 29% of the patients, the use of erythropoietin in 54%, and blood transfusions in 12%. CONCLUSIONS: This retrospective, multicenter study showed that ribavirin as monotherapy may be effective in the treatment of chronic HEV infection; a 3-month course seemed to be an appropriate duration of therapy for most patients.

Daclatasvir plus sofosbuvir, with or without ribavirin, for hepatitis C virus genotype 3 in a French early access programme.

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.

NAFLD and liver transplantation: Current burden and expected challenges.

Because of global epidemics of obesity and type 2 diabetes, the prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing both in Europe and the United States, becoming one of the most frequent causes of chronic liver disease and predictably, one of the leading causes of liver transplantation both for end-stage liver disease and hepatocellular carcinoma. For most transplant teams around the world this will raise many challenges in terms of pre- and post-transplant management. Here we review the multifaceted impact of NAFLD on liver transplantation and will discuss: (1) NAFLD as a frequent cause of cryptogenic cirrhosis, end-stage chronic liver disease, and hepatocellular carcinoma; (2) prevalence of NAFLD as an indication for liver transplantation both in Europe and the United States; (3) the impact of NAFLD on the donor pool; (4) the access of NAFLD patients to liver transplantation and their management on the waiting list in regard to metabolic, renal and vascular comorbidities; (5) the prevalence and consequences of post-transplant metabolic syndrome, recurrent and de novo NAFLD; (6) the alternative management and therapeutic options to improve the long-term outcomes with particular emphasis on the correction and control of metabolic comorbidities.

Multicentre experience using daclatasvir and sofosbuvir to treat hepatitis C recurrence - The ANRS CUPILT study.

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.

Sofosbuvir-based treatment of hepatitis C with severe fibrosis (METAVIR F3/F4) after liver transplantation.

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.

Prognosis of treated severe alcoholic hepatitis in patients with gastrointestinal bleeding.

BACKGROUND & AIMS: All trials on severe alcoholic hepatitis (AH) have included patients with "pure" AH, i.e., without concomitant gastrointestinal bleeding (GIB). Severe AH is often suspected in cirrhotic patients with GIB. We aimed at (1) assessing the prevalence of AH in patients with GIB and Maddrey discriminant function (DF) ⩾32; (2) comparing the outcome in AH patients with or without GIB (AH-GIB+, AH-GIB-); and (3) assessing the performance of the Lille model for survival in AH-GIB+ patients. METHODS: We retrospectively included all patients with alcoholic cirrhosis admitted between January 2005 and March 2011 with the following: (1) jaundice <3 months; (2) DF ⩾32 at admission; (3) bilirubin level >50 µmol/L; and (4) active drinking. Exclusion criteria were advanced hepatocellular carcinoma, other etiology of cirrhosis, severe comorbidities and DF <32 after stabilization. In our centre, we systematically plan a liver biopsy for these patients. Patients with severe AH received prednisolone. RESULTS: We screened 161 patients (86 GIB+, 75 GIB-), and analyzed data for 58 and 47 patients in each group, respectively. The 2 groups did not differ in prevalence of AH (77.3% vs. 81%), demographic data, MELD/Child-Pugh score, or DF. The 2 groups were similar in 6-month probability of survival (73.9 ± 6.0% vs. 69.9 ± 7%, p=0.49). The probability of developing infection was lower for AH-GIB+ patients (24.1% vs. 44.7%, p=0.04). The AUC for the Lille model in predicting 6-month survival was 0.71 ± 0.06 for all patients and 0.74 ± 0.06 for AH-GIB+ patients (p>0.05). CONCLUSIONS: Prevalence of AH is 80% for patients with cirrhosis and GIB, recent jaundice and DF ⩾32. Infection was lower for AH-GIB+ patients, which suggests a beneficial role of antibiotic prophylaxis treatment. Survival among subjects with GIB was the same as among subjects without GIB.

Significant variations in elastometry measurements made within short-term in patients with chronic liver diseases.

BACKGROUND & AIMS: Transient elastometry is a noninvasive procedure used to measure fibrosis when patients are diagnosed with liver disease; it might be used to monitor changes over time. We investigated whether there are short-term variations in stiffness measurements that are not attributable to changes in fibrosis by studying patients with stable liver disease. METHODS: We performed a retrospective analysis of 531 paired liver stiffness measurements made by Fibroscan when the study began (LSM1) and at follow-up (LSM2), more than 1 day and less than 1 year apart, from 432 stable (for body mass index, waist circumference, and alcohol consumption), untreated, immunocompetent patients with chronic liver disease (from January 2006 through March 2009). Variations between the first and follow-up measurements were expressed as absolute (LSM2-LSM1, kPa) or relative ([LSM2-LSM1]/LSM1*100) or as changes in fibrosis stage. RESULTS: There was >20% variation in 49.7%, >30% in 34.3%, and >50% in 12.2% of paired measurements; this variation was constant across the spectrum of LSM1 values. The variations produced a 1-fibrosis stage difference in 31.5% of pairs and a ≥ 2-stage difference in 9.8% of pairs. Patients with LSM1 >7 kPa had increased probability of having a different stage of fibrosis at LSM2, compared with patients with LSM1 <7 kPa. Factors associated with variation included measurements made by 2 different operators or at least 1 non-senior operator, ratios of interquartile range:median values, significant fibrosis (≥ 7 kPa) at LSM1, baseline body mass index, or a 2-fold difference in level of alanine aminotransferase between measurements. When the analyses were restricted to measurements made by the same operator, the variation was slightly reduced; fibrosis stage differed between measurements for only 34.3% of cases. CONCLUSIONS: Operator-related and patient-related factors produce significant variations in liver stiffness measurements made by transient elastometry, limiting its use in monitoring patients. These variations are unrelated to disease progression. The lowest levels of variation occur in measurements made in patients with no or early-stage fibrosis or by a single experienced operator.

Nonalcoholic fatty liver disease increases the risk of hepatocellular carcinoma in patients with alcohol-associated cirrhosis awaiting liver transplants.

BACKGROUND & AIMS: Many patients with alcohol-associated cirrhosis also have diabetes, obesity, or insulin resistance-mediated steatosis, but little is known about how these disorders affect the severity of liver disease. We analyzed the prevalence and prognostic implications of metabolic risk factors (MRFs) such as overweight, diabetes, dyslipidemia, and hypertension in patients with alcohol-associated cirrhosis awaiting liver transplants. METHODS: We performed a retrospective study of 110 patients with alcohol-associated cirrhosis (77% male; mean age, 55 y; 71% with >6 mo of abstinence) who received liver transplants at a single center in Paris, France, from 2000 through 2013. We collected data on previous exposure to MRFs, steatosis (>10% in the explant), and histologically confirmed hepatocellular carcinoma (HCC). RESULTS: HCC was detected in explants from 29 patients (26%). Steatosis was detected in explants from 47 patients (70% were abstinent for ≥6 mo); 50% had a history of overweight or type 2 diabetes. Fifty-two patients (47%) had a history of MRFs and therefore were at risk for nonalcoholic fatty liver disease. A higher proportion of patients with MRF had HCC than those without MRF (46% vs 9%; P < .001). A previous history of overweight or type 2 diabetes significantly increased the risk for HCC (odds ratio, 6.23; 95% confidence interval [CI], 2.47-15.76, and odds ratio, 4.63; 95% CI, 1.87-11.47, respectively; P < .001). MRF, but not steatosis, was associated with the development of HCC (odds ratio, 11.76; 95% CI, 2.60-53; P = .001) independent of age, sex, amount of alcohol intake, or severity of liver disease. CONCLUSIONS: Patients with alcohol-associated cirrhosis who received transplants frequently also had nonalcoholic fatty liver disease. MRFs, particularly overweight, obesity, and type 2 diabetes, significantly increase the risk of HCC.

Efficacy of Sofosbuvir and Daclatasvir in Patients With Fibrosing Cholestatic Hepatitis C After Liver Transplantation.

BACKGROUND & AIMS: Fibrosing cholestatic hepatitis (FCH) is a life-threatening disorder that develops in patients with recurrent hepatitis C virus (HCV) infection after liver transplantation. Until recently, therapeutic options have been limited. We evaluated the efficacy and safety of sofosbuvir- and daclatasvir-based regimens. METHODS: We analyzed data from 23 patients with FCH who participated in a prospective cohort study in France and Belgium of the effects of antiviral agents in patients with recurrence of HCV infection after liver transplantation, from October 2013 through April 2014. Most of the patients had genotype 1 infections that had not responded to previous treatment; 4 patients also were infected with human immunodeficiency virus. Eight patients (37%) had ascites and 15 patients (65%) had bilirubin levels greater than 100 mmol/L; their median serum level of HCV RNA was 7 log IU/mL. The median time between transplantation and treatment initiation was 5 months. Subjects were given either sofosbuvir and daclatasvir (n = 15) or sofosbuvir and ribavirin (n = 8) for 24 weeks. The primary outcome was complete clinical response (survival without re-transplantation, bilirubin level <34 µmol/L, and no ascites or hepatic encephalopathy 36 weeks after treatment began). RESULTS: All patients survived, without re-transplantation, until week 36. Rapid and dramatic improvements in clinical status were observed. The patients' median bilirubin concentration decreased from 122 µmol/L at baseline to a normal value at week 12 of treatment. Twenty-two patients (96%) had a complete clinical response at week 36. Despite the low rate of rapid virologic response, 22 patients (96%) achieved a sustained virologic response at week 12. The only relapse of HCV infection occurred in a patient with human immunodeficiency virus infection who received sofosbuvir and ribavirin. Tolerance was satisfactory, with no grade 3 or 4 adverse events related to sofosbuvir or daclatasvir and no significant interactions among drugs. CONCLUSIONS: Sofosbuvir therapy with daclatasvir or ribavirin leads to major clinical improvement and high rates of sustained virologic response at week 12 in most patients with recurrence of HCV infection and FCH after liver transplantation.

Staging chronic hepatitis C in seven categories using fibrosis biomarker (FibroTest™) and transient elastography (FibroScan®).

BACKGROUND & AIMS: FibroTest™ (FT) and Transient Elastography (TE) have been validated as non-invasive markers of METAVIR fibrosis stages from F0 to F4 using biopsy, and as prognostic markers of liver related mortality in patients with chronic hepatitis C. The aim was to extend the validation of FT and TE as markers of critical steps defined by occurrence of cirrhosis without complications (F4.1), esophageal varices (F4.2), and severe complications (F4.3): primary liver cancer, variceal bleeding, or decompensation (ascites, encephalopathy, or jaundice). METHODS: The updated individual data of 3927 patients (1046 cirrhotics) without complications at baseline were pooled from three prospective cohorts called "EPIC", "Paris", and "Bordeaux" cohorts. RESULTS: At 5 years, among 501 patients without varices at baseline (F4.1) varices occurred in 19 patients [F4.2 incidence of 4.0% (95% CI 2.2-5.8)]. The predictive performance (AUROC) of FT was 0.77 (0.66-0.84; p<0.001). At 10 years severe complications occurred in 203 patients, [F4.3 incidence of 13.4% (9.6-17.1)], including primary liver cancer in 84 patients [6.4% (3.5-9.3)]. FT was predictive (Cox adjusted on treatment) of severe complications [AUROC 0.79 (76-82); p<0.0001], including primary liver cancer [AUROC 0.84 (80-87); p<0.0001]. Similarly TE was predictive of severe complications [AUROC 0.77 (72-81); p<0.0001], including primary liver cancer [AUROC 0.86 (81-90); p<0.0001]. CONCLUSIONS: FibroTest™ and TE increase were associated with the occurrence of all severe complications including hepatocellular carcinoma, hepatic insufficiency, and variceal bleeding. FibroTest™ increase was also associated with the occurrence of esophageal varices.

Staging chronic hepatitis B into seven categories, defining inactive carriers and assessing treatment impact using a fibrosis biomarker (FibroTest®) and elastography (FibroScan®).

BACKGROUND & AIMS: The first aim was to extend the validation of FibroTest® (FT) and transient elastography (TE) as markers of occurrence of cirrhosis without complications (F4.1), oesophageal varices (F4.2), and severe complications (F4.3) in patients with chronic hepatitis B (CHB). The second aim was to validate a previous definition of an inactive carrier based on normal FT and ActiTest® (normal-FT-AT). The third aim was to assess the long-term dynamics of fibrosis in patients with sustained virological response. METHODS: The 10-year updated individual data of 1434 patients were pooled from two prospective cohorts. RESULTS: Of the 1312 patients without a history of complications, varices had occurred after 10 years in 14 patients (F4.2, incidence of 1.7%, 95% CI [0.6-2.8]), and severe complications in 25 (F4.3 3.7% [1.8-5.7]), including hepatocellular carcinoma (HCC) in 21 (3.7% [1.5-5.8]). Using Cox-multivariate analysis adjusted for treatment, viral load, HBeAg status and ALT, FT, and TE were predictive of liver complications (n=37; AUROC=0.83 [0.71-0.90]; p<0.0001) and (n=8/844; AUROC=0.82 [0.72-0.89]; p<0.0001) respectively. Normal FT-AT better identified patients with lower fibrosis progression than the ALT-based standard: 3/163 (1.8%) vs. 16/181 (8.8%; p=0.004) in the Paris cohort, and 5/195 (2.6%) vs. 15/228 (6.6%; p=0.05) in the Bordeaux cohort. Of the 582 responders, 23 had complications (incidence 6.2% [3.2-9.1]) including 19 HCC (5.8% [2.6-9.0]) and 10 with varices (2.6% [0.8-4.4]). Of the 138 responders with advanced fibrosis, only 31% (15-47%) had fibrosis regression. CONCLUSIONS: FibroTest® and TE identified three categories of cirrhosis with increasing morbidity. Normal FibroTest® and ActiTest® were better able to identify inactive hepatitis B carriers than the standard definition. Despite virological response, the overall incidence of cirrhosis increased, with a remaining 5.8% risk of HCC.

Telaprevir activity in treatment-naive patients infected hepatitis C virus genotype 4: a randomized trial.

BACKGROUND: This partially blinded, randomized, phase 2a C210 study evaluated the antiviral activity of telaprevir-based regimens in treatment-naive patients with chronic hepatitis C virus (HCV) genotype 4 infection. METHODS: Twenty-four patients received telaprevir 750 mg every 8 hours for 15 days (T; n = 8), telaprevir in combination with pegylated interferon alfa-2a and ribavirin (Peg-IFN/RBV) for 15 days (TPR; n = 8), or Peg-IFN/RBV plus placebo for 15 days (PR; n = 8), followed by Peg-IFN/RBV for 46 or 48 weeks. The primary objective was to assess the effect of telaprevir on HCV RNA levels. RESULTS: HCV RNA levels decreased slightly with T and PR; TPR produced substantial, rapid declines. On day 15, median reductions in the HCV RNA load from baseline were -0.77, -4.32, and -1.58 log10 IU/mL for T, TPR, and PR, respectively, and 0 patients in the T group, 1 in the TPR group, and 0 in the PR group had undetectable HCV RNA. Five of 8 patients who received telaprevir monotherapy had viral breakthrough within 15 days of treatment. Adverse event incidence was similar across treatments and comparable with the incidences from previous clinical trials. One patient (in T group) had a serious adverse event (considered unrelated to telaprevir) that led to treatment discontinuation. CONCLUSIONS: Telaprevir with Peg-IFN/RBV had greater activity than Peg-IFN/RBV treatment or telaprevir monotherapy against HCV genotype 4. Telaprevir was generally safe and well tolerated. Further investigation of telaprevir combination therapy in patients with HCV genotype 4 infection is warranted.
