Background & Aims
Check point inhibitors (CPI) have improved survival of oncology patients but adverse effects that mimic autoimmune disorders have been reported. Our aim was describe the ...characteristics of immune‐related hepatitis (irH) and prognosis, and compared them to those of patients with autoimmune hepatitis (AIH).
Methods
This is a retrospective study including all grade ≥ 3 (severe) irH diagnosed among 414 patients treated with CPI from 2016 to 2018.
Results
Twenty‐eight cases of severe irH were recorded: 10 on anti‐CTLA‐4 ± anti‐PD1/PD‐L1 and 18 on anti‐PD1/PD‐L1. Half were female, age 63 years, median time on CPI three cycles. Four (14.3%) presented acute liver injury or failure and one (3.6%) died as consequence. 94% presented normal immunoglobulin G (IgG). Six (21.4%) patients were retreated with CPI and none presented relapse or new immune‐related adverse events after a median cycles of 11 (range 6‐36). Subjects with irH were older and had lower IgG values than a cohort of AIH (N = 38). Presentation tended to be more severe in AIH. Twenty‐five percent of irH and 84% AIH presented ANAs ≥ 1:80 (P = .001). In irH Initial dose of corticosteroids was higher (60 vs 30 mg, P < .001) but duration shorter (2.3 vs 7 months, P < .001) and frequently in monotherapy (41.7% vs 91.3%, P < .001).
Conclusions
Immune‐related hepatitis can lead to acute liver failure, with absence of increased values of IgG and ANAs. In contrast to autoimmune hepatitis, initial corticosteroids dose were higher, duration shorter with few requiring additional immunosuppression. Retreatment with CPI was not associated with recurrence.

•After the approval of DAAs, post-liver transplant survival has significantly increased.•The improved survival of LT recipients is exclusive to anti-HCV positive patients.•A high ...access to DAAs before and while on the wait-list and after LT explains these results.•DAAs also result in a significant decrease in anti-HCV patients included on the wait-list.
The efficacy of direct-acting antivirals (DAAs) has dramatically changed the prognosis of patients with chronic hepatitis C. We aimed to evaluate the impact of DAA therapy on the composition of the liver transplant (LT) waiting list and the early post-transplant survival.
We evaluated all patients admitted to the waiting list for a primary LT between 1st January 2008 and 31st of December 2016 in Catalonia, Spain. Time span was divided into two periods according to the availability of different antiviral therapies: 2008–2013 (interferon-based therapies) and 2014–2016 (DAA). Changes in the indications of LT and the aetiology of liver disease, as well as post-LT patient survival, were evaluated according to the year of inclusion and transplantation, respectively.
We included 1,483 patients. Admissions in the waiting list for hepatitis C virus (HCV)-related liver disease decreased significantly, from 47% in 2008–2013 to 35% in 2014–2016 (p <0.001), particularly because of a reduction in patients with decompensated cirrhosis. In contrast, NASH-related inclusions increased from 4% to 7% (p = 0.003). Three-year post-LT patient survival increased significantly in the second period in the whole cohort (82% vs. 91%, p = 0.002), because of better survival in anti-HCV positive patients (76% vs. 91%, p = 0.001), but not in anti-HCV negative patients (88% vs. 91% p = 0.359). Anti-HCV positive serology, the time period of 2008–2013 and higher donor age were independently associated with post-LT mortality in the whole cohort; while time period and donor age were independently associated with post-LT mortality in anti-HCV positive recipients.
The high efficacy of DAAs is associated with significant changes in the composition of the LT waiting list and, more importantly, results in improved post-transplant survival.
The efficacy of the new direct-acting antivirals is associated with a significant improvement in survival of patients undergoing liver transplantation because of hepatitis C virus-related liver disease. In addition, it has decreased the number of patients with hepatitis C that need a liver transplant.
Recurrent hepatitis C virus (HCV) infection after liver transplantation (LT) is associated with accelerated progression of liver disease, frequently leading to graft loss and early death. Existing ...treatment options for severe recurrent HCV infection are limited by suboptimal efficacy, poor tolerability, and numerous drug interactions. We provided sofosbuvir (SOF) and ribavirin (RBV) on a compassionate‐use basis to patients with severe recurrent hepatitis C, including those with fibrosing cholestatic hepatitis (FCH) and decompensated cirrhosis who had a life expectancy of 1 year or less. All patients were to receive 24‐48 weeks of SOF plus RBV. Investigators could add pegylated interferon to the regimen at their discretion. Data from the first 104 patients who completed or prematurely discontinued treatment by January 1, 2014 are presented. Of the 104 patients analyzed, 52 had an early severe recurrence (diagnosed <12 months after LT) and 52 had cirrhosis (diagnosed >12 months after LT). Twelve patients who underwent retransplantation were excluded from our efficacy analysis. Of the 92 patients assessed, 54 (59%) achieved sustained virological response (SVR) at 12 weeks after the end of treatment, with a higher rate (73%; 35 of 48) in patients with early severe recurrence. Of the 103 patients assessed for clinical outcome, 59 (57%) reported clinical improvement at the last study visit, 23 (22%) were unchanged, 3 (3%) had a worsened clinical status, and 13 (13%) died. Overall, 123 serious adverse events (SAEs) occurred in 49 patients (47%). SAEs associated with hepatic decompensation were the most frequent, with 26 SAEs occurring in 19 patients (18%). Conclusion: SOF and RBV provide high rates of SVR in patients with severe recurrent HCV, including patients with early severe recurrence, FCH, and cirrhosis. (Hepatology 2015;61:1485–1494)
Frailty and sarcopenia are well-recognized factors related to worse outcomes in patients with cirrhosis, including liver transplant (LT) candidates. Implications of pre-LT functional and muscle ...deterioration also affect post-LT outcomes. Patients with cirrhosis and acute-on-chronic liver failure (ACLF) have a lower survival rate, both before and after LT. There is a need to better identify those patients with ACLF who would benefit from LT. This review aims to present the available data about frailty and sarcopenia in patients with ACLF in the LT setting. An exhaustive review of the published literature was conducted. Data regarding frailty and sarcopenia in LT candidates with ACLF are scarce and heterogeneous. Studies evaluating frailty and sarcopenia in critically ill patients outside the liver literature are also presented in this review to enrich the knowledge of this field in expansion. Frailty and sarcopenia seem to contribute to worse outcomes in LT candidates with ACLF, both before and after LT. Sarcopenia evaluation may be the most prudent approach for those very sick patients. Skeletal muscle index assessed by computed tomography is recommended to evaluate sarcopenia. The role of muscle ultrasound and bioelectrical impedance analysis is to be determined. Frailty and sarcopenia are crucial factors to consider on a case-by-case basis in LT candidates with ACLF to improve patient outcomes.

•Antiviral therapy with direct-acting antivirals is safe and effective in patients awaiting liver transplantation.•Baseline liver function and the use of two direct-acting antivirals ...were independent predictors of a sustained virological response.•Antiviral therapy improves liver function and allows delisting as a result of clinical improvement in a quarter of treated patients.
Antiviral therapy for the treatment of hepatitis C (HCV) infection has proved to be safe and efficacious in patients with cirrhosis awaiting liver transplantation (LT). However, the information regarding the clinical impact of viral eradication in patients on the waiting list is still limited. The aim of the study was to investigate the probability of delisting in patients who underwent antiviral therapy, and the clinical outcomes of these delisted patients.
Observational, multicenter and retrospective analysis was carried out on prospectively collected data from patients positive for HCV, treated with an interferon-free regimen, while awaiting LT in 18 hospitals in Spain.
In total, 238 patients were enrolled in the study. The indication for LT was decompensated cirrhosis (with or without hepatocellular carcinoma HCC) in 171 (72%) patients, and HCC in 67 (28%) patients. Sustained virologic response (SVR) rate was significantly higher in patients with compensated cirrhosis and HCC (92% vs. 83% in patients with decompensated cirrhosis with or without HCC, p=0.042). Among 122 patients with decompensated cirrhosis without HCC, 29 (24%) were delisted due to improvement. No patient with baseline MELD score >20 was delisted. After delisting (median follow-up of 88weeks), three patients had clinical decompensations and three had de novo HCC. Only two of the patients with HCC had to be re-admitted onto the waiting list. The remaining 23 patients remained stable, with no indication for LT.
Antiviral therapy is safe and efficacious in patients awaiting LT. A quarter of patients with decompensated cirrhosis can be delisted asa result of clinical improvement, which appears to be remain stable in most patients. Thus, delisting is a safe strategy that could spare organs and benefit other patients with a more urgent need.
Antiviral therapy in patients awaiting liver transplantation is safe and efficacious. Viral eradication allows removal from the waiting list of a quarter of treated patients. Delisting because of clinical improvement is a safe strategy that can spare organs for patients in urgent need.

•Study patients had recurrent hepatitis C infection following liver transplantation.•The study included patients with cirrhosis (18%) and genotype 3 HCV (44%).•Twelve weeks of ...sofosbuvir/velpatasvir resulted in an SVR12 of 96%.•No liver transplant rejection episodes or deaths occurred.•Treatment did not impact immunosuppressive therapy.
Sofosbuvir, an NS5B inhibitor, combined with velpatasvir, an NS5A inhibitor (SOF/VEL), produces high sustained virologic response rates 12 weeks after treatment (SVR12) in patients with genotype 1–6 HCV infection, and has no anticipated clinically relevant drug-drug interactions with immunosuppressants. This study evaluated the safety and efficacy of SOF/VEL in adults with recurrent chronic genotype 1–4 HCV infection after liver transplant.
Patients received SOF/VEL 400/100 mg daily for 12 weeks. Patients could be treatment experienced or treatment naïve with no cirrhosis or with compensated cirrhosis. The primary endpoints were SVR12 and discontinuations due to adverse events.
A total of 79 patients were enrolled and treated in this study (37 47% had genotype 1, 3 4% genotype 2, 35 44% genotype 3, and 4 5% genotype 4 HCV). Of these, 81% were male, 82% were white, 18% had compensated cirrhosis, and 59% were treatment experienced. The most commonly used immunosuppressants were tacrolimus (71%), mycophenolic acid (24%), cyclosporine (14%), and azathioprine (11%). Median (range) time from liver transplantation was 7.5 (0.3, 23.9) years. The SVR12 rate was 96%. By genotype, SVR12 rates were 95% (genotype 1), 100% (genotype 2), 97% (genotype 3), and 100% (genotype 4). Two patients experienced virologic relapse: one with genotype 1a infection was non-cirrhotic and treatment naïve, and one with genotype 3 infection was non-cirrhotic and treatment experienced. One patient discontinued SOF/VEL due to hyperglycemia. No serious or severe adverse events were deemed SOF/VEL-related by the investigator, and no liver transplant rejection episodes or deaths occurred during the study period.
Treatment with SOF/VEL for 12 weeks was highly effective and well tolerated in genotype 1–4 HCV-infected liver transplant recipients with and without cirrhosis.
Sofosbuvir/velpatasvir is a combination of two drugs in one tablet that is approved for the treatment of patients with chronic hepatitis C virus (HCV) infection. When patients with chronic HCV infection receive a liver transplant, the HCV infection usually recurs, and damages the transplanted liver. This study tested the effects of 12 weeks of sofosbuvir/velpatasvir treatment in patients who had HCV recurrence after a liver transplant. Three months following the end of treatment, 96% of patients were cured of HCV infection.
Clinical trial number: NCT02781571.
The epidemiological and clinical characteristics of solid organ transplant (SOT) patients during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic remains unclear. We ...conducted a matched retrospective cohort study to compare clinical outcomes among SOT recipients with the general population and to assess immunosuppression management.
Adult SOT recipients with laboratory polymerase chain reaction-confirmed SARS-CoV-2 infection admitted to a tertiary-care hospital in Barcelona, Spain, from March 11 to April 25, 2020, were matched to controls (1:4) on the basis of sex, age, and age-adjusted Charlson's Index. Patients were followed for up to 28 days from admission or until censored. Primary endpoint was mortality at 28 days. Secondary endpoints included admission to the intensive care unit and secondary complications. Drug-drug interactions (DDI) between immunosuppressants and coronavirus disease 2019 (COVID-19) management medication were collected.
Forty-six transplant recipients and 166 control patients were included. Mean (SD) age of transplant recipients and controls was 62.7 (12.6) and 66.0 (12.7) years, 33 (71.7%) and 122 (73.5%) were male, and median (interquartile range) Charlson's Index was 5 (3-7) and 4 (2-7), respectively. Mortality was 37.0% in SOT recipients and 22.9% in controls (P = 0.51). Thirty-three (71.7%) patients underwent transitory discontinuation of immunosuppressants due to potential or confirmed DDI.
In conclusion, hospitalized SOT recipients with COVID-19 had a trend toward higher mortality compared with controls, although it was not statistically significant, and a notable propensity for DDI.
Acute and chronic hepatitis E have been associated with high mortality and development of cirrhosis, particularly in solid-organ recipients and patients infected by human immunodeficiency virus. ...However, data regarding the epidemiology of hepatitis E in special populations is still limited.
Investigate seroprevalence and possible factors associated with HEV infection in a large cohort of immunosuppressed patients.
Cross-sectional study testing IgG anti-HEV in serum samples from 1373 consecutive individuals: 332 liver-transplant, 296 kidney-transplant, 6 dual organ recipients, 301 non-transplanted patients with chronic liver disease, 238 HIV-infected patients and 200 healthy controls.
IgG anti-HEV was detected in 3.5% controls, 3.7% kidney recipients, 7.4% liver transplant without cirrhosis and 32.1% patients who developed post-transplant cirrhosis (p<0.01). In patients with chronic liver disease, IgG anti-HEV was also statistically higher in those with liver cirrhosis (2% vs 17.5%, p<0.01). HIV-infected patients showed an IgG anti-HEV rate of 9.2%, higher than those patients without HIV infection (p<0.03). Multivariate analysis showed that the factors independently associated with anti-HEV detection were liver cirrhosis, liver transplantation and HIV infection (OR: 7.6, 3.1 and 2.4). HCV infection was a protective factor for HEV infection (OR: 0.4).
HEV seroprevalence was high in liver transplant recipients, particularly those with liver cirrhosis. The difference in anti-HEV prevalence between Liver and Kidney transplanted cases suggests an association with advanced liver disease. Further research is needed to ascertain whether cirrhosis is a predisposing factor for HEV infection or whether HEV infection may play a role in the pathogeneses of cirrhosis.
Direct‐acting antiviral agents (DAAs) are highly effective and well tolerated in patients with chronic hepatitis C virus infection, including those with compensated cirrhosis. However, fewer data are ...available in patients with more advanced liver disease. Our retrospective, noninterventional, national, multicenter study in patients from the Spanish Hepa‐C registry investigated the effectiveness and safety of interferon‐free DAA regimens in patients with advanced liver disease, including those with decompensated cirrhosis, in routine practice (all currently approved regimens were registered). Patients transplanted during treatment or within 12 weeks of completing treatment were excluded. Among 843 patients with cirrhosis (Child‐Turcotte‐Pugh CTP class A, n = 564; CTP class B/C, n = 175), 90% achieved sustained virologic response 12 weeks after treatment (SVR12). Significant differences in SVR12 and relapse rates were observed between CTP class A and CTP class B/C patients (94% versus 78%, and 4% versus 14%, respectively; both P < 0.001). Serious adverse events (SAEs) were more common in CTP class B/C versus CTP class A patients (50% versus 12%, respectively; P < 0.001). Incident decompensation was the most common serious adverse event (7% overall). Death rate during the study period was 16/843 (2%), significantly higher among CTP class B/C versus CTP class A patients (6.4% versus 0.9%; P < 0.001). Baseline Model for End‐Stage Liver Disease (MELD) score alone (cut‐off 18) was the best predictor of survival. Conclusion: Patients with decompensated cirrhosis receiving DAAs present lower response rates and experience more SAEs. In this setting, a MELD score ≥18 may help clinicians to identify those patients with a higher risk of complications and to individualize treatment decisions. (Hepatology 2017;65:1810‐1822).
