ABSTRACT
BACKGROUND AND AIMS: Around 750,000 patients per year will be cured of HCV infection until 2030. Those with compensated advanced chronic liver disease remain at risk for hepatic decompensation and de novo HCC. Algorithms have been developed to stratify risk early after cure; however, data on long-term outcomes and the prognostic utility of these risk stratification algorithms at later time points are lacking. APPROACH AND RESULTS: We retrospectively analyzed a cohort of 2335 patients with compensated advanced chronic liver disease (liver stiffness measurement≥10 kPa) who achieved HCV-cure by interferon-free therapies from 15 European centers (median age 60.2±11.9 y, 21.1% obesity, 21.2% diabetes).During a median follow-up of 6 years, first hepatic decompensation occurred in 84 patients (3.6%, incidence rate: 0.74%/y, cumulative incidence at 6 y: 3.2%); 183 (7.8%) patients developed de novo HCC (incidence rate: 1.60%/y, cumulative incidence at 6 y: 8.3%), with both risks being strictly linear over time.Baveno VII criteria to exclude (FU-liver stiffness measurement <12 kPa and follow-up platelet count >150 g/L) or rule-in (FU-liver stiffness measurement ≥25 kPa) clinically significant portal hypertension (CSPH) stratified the risk of hepatic decompensation with proportional hazards. Estimated probability of CSPH discriminated patients developing versus not developing hepatic decompensation in the gray zone (ie, patients meeting none of the above criteria).Published HCC risk stratification algorithms identified high-incidence and low-incidence groups; however, the size of the latter group varied substantially (9.9%-69.1%). A granular "HCC-sustained virologic response" model was developed to inform an individual patient's HCC risk after HCV-cure. CONCLUSIONS: In patients with compensated advanced chronic liver disease, the risks of hepatic decompensation and HCC remain constant after HCV-cure, even in the long term (>3 y). One-time post-treatment risk stratification based on noninvasive criteria provides important prognostic information that is maintained during long-term follow-up, as the hazards remain proportional over time.
ABSTRACT
BACKGROUND & AIMS: Baveno VII has defined a clinically significant (i.e., prognostically meaningful) decrease in liver stiffness measurement (LSM) in cACLD as a decrease of ≥20% associated with a final LSM <20 kPa or any decrease to <10 kPa. However, these rules have not yet been validated against direct clinical endpoints. METHODS: We retrospectively analysed patients with cACLD (LSM ≥10 kPa) with paired liver stiffness measurement (LSM) before (BL) and after (FU) HCV cure by interferon-free therapies from 15 European centres. The cumulative incidence of hepatic decompensation was compared according to these criteria, considering hepatocellular carcinoma and non-liver-related death as competing risks. RESULTS: A total of 2,335 patients followed for a median of 6 years were analysed. Median BL-LSM was 16.6 kPa with 37.1% having ≥20 kPa. After HCV cure, FU-LSM decreased to a median of 10.9 kPa (<10 kPa: 1,002 [42.9%], ≥20 kPa: 465 [19.9%]) translating into a median LSM change of -5.3 (-8.8 to -2.4) kPa corresponding to -33.9 (-48.0 to -15.9) %. Patients achieving a clinically significant decrease (65.4%) had a significantly lower risk of hepatic decompensation (subdistribution hazard ratio: 0.12, 95% CI 0.04-0.35, p <0.001). However, these risk differences were primarily driven by a negligible risk in patients with FU-LSM <10 kPa (5-year cumulative incidence: 0.3%) compared to a high risk in patients with FU-LSM ≥20 kPa (16.6%). Patients with FU-LSM 10-19.9 kPa (37.4%) also had a low risk of hepatic decompensation (5-year cumulative incidence: 1.7%), and importantly, the risk of hepatic decompensation did not differ between those with/without an LSM decrease of ≥20% (p = 0.550). CONCLUSIONS: FU-LSM is key for risk stratification after HCV cure and should guide clinical decision making. LSM dynamics do not hold significant prognostic information in patients with FU-LSM 10-19.9 kPa, and thus, their consideration is not of sufficient incremental value in the specific context of HCV cure. IMPACT AND IMPLICATIONS: Liver stiffness measurement (LSM) is increasingly applied as a prognostic biomarker and commonly decreases in patients with compensated advanced chronic liver disease achieving HCV cure. Although Baveno VII proposed criteria for a clinically significant decrease, little is known about the prognostic utility of LSM dynamics (changes through antiviral therapy). Interestingly, in those with a post-treatment LSM of 10-19.9 kPa, LSM dynamics did not provide incremental information, arguing against the consideration of LSM dynamics as prognostic criteria. Thus, post-treatment LSM should guide the management of patients with compensated advanced chronic liver disease achieving HCV cure.

BACKGROUND & AIMS: In primary biliary cholangitis (PBC), static liver stiffness measurement (LSM) has proven prognostic value. However, the added prognostic value of LSM time course in this disease remains uncertain. METHODS: We conducted an international retrospective cohort study among patients with PBC treated with ursodeoxycholic acid and followed by vibration-controlled transient elastography between 2003 and 2022. Using joint modeling, the association of LSM trajectory and the incidence of serious clinical events (SCE), defined as cirrhosis complications, liver transplantation, or death, was quantified using the hazard ratio and its confidence interval. RESULTS: A total of 6362 LSMs were performed in 3078 patients (2007 on ursodeoxycholic acid alone; 13% with cirrhosis), in whom 316 SCE occurred over 14,445 person-years (median follow-up, 4.2 years; incidence rate, 21.9 per 1000 person-years). LSM progressed in 59% of patients (mean, 0.39 kPa/year). After adjusting for prognostic factors at baseline, including LSM, any relative change in LSM was associated with a significant variation in SCE risk (P < .001). For example, the adjusted hazard ratios (95% confidence interval) associated with a 20% annual variation in LSM were 2.13 (1.89-2.45) for the increase and 0.40 (0.33-0.46) for the decrease. The association between LSM trajectory and SCE risk persisted regardless of treatment response or duration, when patients with cirrhosis were excluded, and when only death or liver transplantation was considered. CONCLUSIONS: Tracking longitudinal changes in LSM using vibration-controlled transient elastography provides valuable insights into PBC prognosis, offering a robust predictive measure for the risk of SCE. LSM could be used as a clinically relevant surrogate end point in PBC clinical trials.
ABSTRACT
Recommended post-liver transplant (LT) prophylaxis in patients with hepatitis delta includes a nucleos(t)ide analogue (NA) and anti-hepatitis B immunoglobulin (HBIG) indefinitely. We analysed the use of HBIG in real-life clinical practice and its impact on HBV/HDV recurrence in 174 HDV-related LT patients from 10 Spanish liver transplant centres (1988-2018). Median post-LT follow-up was 7.8 (2.3-15.1) years and patient survival at 5 years was 90%. Most patients (97%) received HBIG in the immediate post-LT, but only 42% were on HBIG at the last control. Among those discontinuing HBIG, the median time on treatment was 18 (7-52) months. Post-LT HBsAg+ was detected in 16 (9%) patients and HBV-DNA in 12 (7%). Despite HBsAg positivity, HDV recurrence was reported only in three patients (1.7%), all of whom were not receiving NA and had discontinued HBIG. Our data suggest that a finite HBIG prophylaxis in HDV-LT is feasible, especially if high-barrier NAs are used.

BACKGROUND: The optimal cardiovascular assessment of liver transplant (LT) candidates is unclear. We aimed to evaluate the performance of CT-based coronary tests (coronary artery calcium score [CACS] and coronary CT angiography [CCTA]) and a modification of the CAD-LT score (mCAD-LT, excluding family history of CAD) to diagnose significant coronary artery disease (CAD) before LT and predict the incidence of post-LT cardiovascular events (CVE). METHODS: We retrospectively analysed a single-centre cohort of LT candidates who underwent non-invasive tests; invasive coronary angiography (ICA) was performed depending on the results of non-invasive tests. mCAD-LT was calculated in all patients. RESULTS: Six-hundred-and-thirty-four LT candidates were assessed and 351 of them underwent LT. CACS, CCTA and ICA were performed in 245, 123 and 120 LT candidates, respectively. Significant CAD was found in 30% of patients undergoing ICA. The AUROCs of mCAD-LT (.722) and CCTA (.654) were significantly higher than that of CACS (.502) to predict the presence of significant CAD. Specificity of the tests ranged between 31% for CCTA and 53% for CACS. Among patients who underwent LT, CACS ≥ 400 and mCAD-LT were independently associated with the incidence of CVE; in patients who underwent CCTA before LT, significant CAD at CCTA also predicted post-LT CVE. CONCLUSION: In this cohort, mCAD-LT score and CT-based tests detect the presence of significant CAD in LT candidates, although they tend to overestimate it. Both mCAD-LT score and CT-based tests classify LT recipients according to their risk of post-LT CVE and can be used to improve post-LT risk mitigation.

BACKGROUND AND AIMS: Chronic hepatitis D (CHD) is a severe form of chronic viral hepatitis. The estimated hepatitis delta prevalence in Spain is around 5% of patients with hepatitis B. Reimbursement of new antiviral therapies (Bulevirtide, BLV) was delayed in our country until February 2024. We aimed to characterize the clinical profile of patients with HDV/HBV infection in Spain and current barriers in their management at the time of BLV approval. METHOD: Multicenter registry including patients with positive anti-HDV serology actively monitored in 30 Spanish centers. Epidemiological, clinical and virological variables were recorded at the start of follow-up and at the last visit. RESULTS: We identified 329 anti-HDV patients, 41% were female with median age 51 years. The most common geographical origin was Spain (53%) and East Europe (24%). Patients from Spain were older and had HCV and HIV coinfection probably associated to past drug injection (p<0.01). HDV-RNA was positive in 138 of 221 assessed (62%). Liver cirrhosis was present at diagnosis in 33% and it was more frequent among viremic patients (58% vs 25%, p<0.01). After a median follow-up of 6 (3-12) years, 44 (16%) resolved infection (18 spontaneously and 26 after Peg-INF). An additional 10% of patients developed cirrhosis (n=137) during follow-up (45% had portal hypertension and 14% liver decompensation). Liver disease progression was associated to persisting viremia. CONCLUSION: One-third of the patients with CHD already have cirrhosis at diagnosis. Persistence of positive viremia is associated to rapid liver disease progression. Importantly, barriers to locally determine/quantify HDV-RNA were present.
ABSTRACT
BACKGROUND AND AIMS: HIV-positive patients on tenofovir hydroxyl fumarate (TDF)/emtricitabine have a lower risk of COVID-19 and hospitalization than those given other treatments. Our aim was to analyze the severity of COVID-19 in patients with chronic hepatitis B (CHB) on TDF or entecavir (ETV). METHODS: Spanish hospital databases (n = 28) including information regarding adult CHB patients on TDF or ETV for the period February 1st to November 30th 2020 were searched for COVID-19, defined as a positive SARS-CoV-2 polymerase chain reaction, and for severe COVID-19. RESULTS: Of 4736 patients, 117 had COVID-19 (2.5%), 67 on TDF and 50 on ETV. Compared to patients on TDF, those on ETV showed (p < 0.05) greater rates of obesity, diabetes, ischemic cardiopathy, and hypertension. COVID-19 incidence was similar in both groups (2.3 vs. 2.6%). Compared to TDF, patients on ETV more often (p < 0.01) had severe COVID-19 (36 vs. 6%), required intensive care unit (ICU) (10% vs. 0) or ventilatory support (20 vs. 3%), were hospitalized for longer (10.8 ± 19 vs. 3.1 ± 7 days) or died (10 vs. 1.5%, p = 0.08). In an IPTW propensity score analysis adjusted for age, sex, obesity, comorbidities, and fibrosis stage, TDF was associated with a sixfold reduction in severe COVID-19 risk (adjusted-IPTW-OR 0.17, 95%CI 0.04-0.67, p = 0.01). CONCLUSION: Compared to ETV, TDF seems to play a protective role in CHB patients with SARS-CoV-2 whereby the risk of severe COVID-19 is lowered.

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) is a major cause of morbidity and mortality in patients with advanced chronic liver disease (ACLD) caused by chronic hepatitis C who have achieved sustained virologic response (SVR). We developed risk stratification algorithms for de novo HCC development after SVR and validated them in an independent cohort. METHODS: We evaluated the occurrence of de novo HCC in a derivation cohort of 527 patients with pre-treatment ACLD and SVR to interferon-free therapy, in whom alpha-fetoprotein (AFP) and non-invasive surrogates of portal hypertension including liver stiffness measurement (LSM) were assessed pre-/post-treatment. We validated our results in 1,500 patients with compensated ACLD (cACLD) from other European centers. RESULTS: During a median follow-up (FU) of 41 months, 22/475 patients with cACLD (4.6%, 1.45/100 patient-years) vs. 12/52 decompensated patients (23.1%, 7.00/100 patient-years, p <0.001) developed de novo HCC. Since decompensated patients were at substantial HCC risk, we focused on cACLD for all further analyses. In cACLD, post-treatment-values showed a higher discriminative ability for patients with/without de novo HCC development during FU than pre-treatment values or absolute/relative changes. Models based on post-treatment AFP, alcohol consumption (optional), age, LSM, and albumin, accurately predicted de novo HCC development (bootstrapped Harrel's C with/without considering alcohol: 0.893/0.836). Importantly, these parameters also provided independent prognostic information in competing risk analysis and accurately stratified patients into low- (~2/3 of patients) and high-risk (~1/3 of patients) groups in the derivation (algorithm with alcohol consumption; 4-year HCC-risk: 0% vs. 16.5%) and validation (3.3% vs. 17.5%) cohorts. An alternative approach based on alcohol consumption (optional), age, LSM, and albumin (i.e., without AFP) also showed a robust performance. CONCLUSIONS: Simple algorithms based on post-treatment age/albumin/LSM, and optionally, AFP and alcohol consumption, accurately stratified patients with cACLD based on their risk of de novo HCC after SVR. Approximately two-thirds were identified as having an HCC risk <1%/year in both the derivation and validation cohort, thereby clearly falling below the cost-effectiveness threshold for HCC surveillance. LAY SUMMARY: Simple algorithms based on age, alcohol consumption, results of blood tests (albumin and α-fetoprotein), as well as liver stiffness measurement after the end of hepatitis C treatment identify a large proportion (approximately two-thirds) of patients with advanced but still asymptomatic liver disease who are at very low risk (<1%/year) of liver cancer development, and thus, might not need to undergo 6-monthly liver ultrasound.

BACKGROUND & AIMS: It remains unclear whether rectal colonization with multidrug-resistant organisms (MDROs) is prevalent and predisposes to infections by the same pathogens in patients with cirrhosis. METHODS: Two series of critically ill patients were evaluated. In the Barcelona cohort, 486 consecutive patients were prospectively evaluated, 129 with and 357 without cirrhosis (2015-2016). Rectal swabs were performed at admission and weekly thereafter (until intensive care unit [ICU] discharge) to detect MDRO colonization. Risk factors for colonization and infection by MDROs were evaluated. A retrospective cohort from Frankfurt (421 patients with cirrhosis; 2010-2018) was investigated to evaluate MDRO rectal colonization in another epidemiological scenario. RESULTS: In the Barcelona cohort, 159 patients were colonized by MDROs (32.7%), 102 (64.2%) at admission and 57 (35.8%) during follow-up. Patients with cirrhosis showed higher rates of rectal colonization at admission than those without cirrhosis (28.7% vs. 18.2%, p = 0.01) but similar colonization rates during ICU stay. Extended-spectrum beta-lactamase-Enterobacterales were the most frequent MDROs isolated in both groups. Colonization by MDROs independently increased the risk of infection by MDROs at admission and during follow-up. Risk of new infection by the colonizing strain was also significantly increased in patients with (hazard ratio [HR] 7.41) and without (HR 5.65) cirrhosis. Rectal colonization by MDROs was also highly prevalent in Frankfurt (n = 198; 47%; 131 at admission [66.2%] and 67 [33.8%] during follow-up), with vancomycin-resistant enterococci being the most frequent colonizing organism. Rectal colonization by MDROs was also associated with an increased risk of infection by MDROs in this cohort. Infections occurring in MDR carriers were mainly caused by the colonizing strain. CONCLUSION: Rectal colonization by MDROs is extremely frequent in critically ill patients with cirrhosis. Colonization increases the risk of infection by the colonizing resistant strain. LAY SUMMARY: Rectal colonization by multidrug-resistant organisms (MDROs) is a prevalent problem in patients with cirrhosis requiring critical care. The pattern of colonizing bacteria is heterogeneous with relevant differences between centers. Colonization by MDROs is associated with increased risk of infection by the colonizing bacteria in the short term. This finding suggests that colonization data could be used to guide empirical antibiotic therapy and de-escalation policies in patients with cirrhosis.

BACKGROUND & AIMS: Factors associated with a successful outcome upon nucleos(t)ide analogue (NA) treatment withdrawal in HBeAg-negative chronic hepatitis B (CHB) patients have yet to be clarified. The objective of this study was to analyse the HBV-specific T cell response, in parallel with peripheral and intrahepatic viral parameters, in patients undergoing NA discontinuation. METHODS: Twenty-seven patients without cirrhosis with HBeAg-negative CHB with complete viral suppression (>3 years) were studied prospectively. Intrahepatic HBV-DNA (iHBV-DNA), intrahepatic HBV-RNA (iHBV-RNA), and covalently closed circular DNA (cccDNA) were quantified at baseline. Additionally, serum markers (HBV-DNA, HBsAg, HBV core-related antigen [HBcrAg] and HBV-RNA) and HBV-specific T cell responses were analysed at baseline and longitudinally throughout follow-up. RESULTS: After a median follow-up of 34 months, 22/27 patients (82%) remained off-therapy, of whom 8 patients (30% of the total cohort) lost HBsAg. Baseline HBsAg significantly correlated with iHBV-DNA and iHBV-RNA, and these parameters were lower in patients who lost HBsAg. All patients had similar levels of detectable cccDNA regardless of their clinical outcome. Patients achieving functional cure had baseline HBsAg levels ≤1,000 IU/ml. Similarly, an increased frequency of functional HBV-specific CD8+ T cells at baseline was associated with sustained viral control off treatment. These HBV-specific T cell responses persisted, but did not increase, after treatment withdrawal. A similar, but not statistically significant trend, was observed for HBV-specific CD4+ T cell responses. CONCLUSIONS: Decreased cccDNA transcription and low HBsAg levels are associated with HBsAg loss upon NA discontinuation in patients with HBeAg-negative CHB. The presence of functional HBV-specific T cells at baseline are associated with a successful outcome after treatment withdrawal. LAY SUMMARY: Nucleos(t)ide analogue therapy can be discontinued in a high proportion of chronic hepatitis B patients without cirrhosis. The strength of HBV-specific immune T cell responses may contribute to successful viral control after antiviral treatment interruption. Our comprehensive study provides in-depth data on virological and immunological factors than can help guide individualised therapy in patients with chronic hepatitis B.

The hepatitis B (HBV) vaccine is recommended in unvaccinated adults with cirrhosis, despite its low efficacy. We aimed to evaluate the response to a double-dose/accelerated vaccine schedule in patients with cirrhosis admitted into a hepatology ward. All patients with cirrhosis admitted to the hepatology ward without exclusion criteria were offered the HBV HBVAXPRO 40mcg vaccine at months 0, 1 and 2. Non-responders received a second cycle. We evaluated 468 patients and only 19% were seroprotected against HBV. In 196 patients without exclusion criteria for HBV vaccination, the per protocol response rate (anti-HBs >10 U/ml) was 23% after a first cycle and 59% after a second cycle. The overall response per intention to treat was only 23%. We have not identified predictors of response. Only one patient had a mild adverse event. Most patients with cirrhosis admitted in the hepatology ward are unprotected against HBV. Although a second HBV vaccination cycle increases the response rate, the poor overall response reinforces the implementation of HBV vaccination before the development of cirrhosis.

A significant proportion of patients infected with SARS-CoV-2 develop severe respiratory symptoms due to an excessive immune response. Treatment of this condition may include immunosuppressive therapies, such as IL-6 receptor antagonists and corticosteroids, which pose a risk for patients with active or past hepatitis B virus (HBV) infection. In this prospective cohort study, we analysed the risk of HBV reactivation in patients with severe COVID-19 and resolved HBV infection undergoing immunosuppressive therapy. From 15th March to 30th April 2020, 600 patients with severe COVID-19 were admitted to our hospital and treated with immune modulators. Data regarding HBV infection were available in 484, of whom 69 (14%) were HBsAg negative/anti-HBc positive. For these patients, HBV reactivation prophylaxis with entecavir was strongly recommended. Complete follow-up was available in 61 patients: 72% were male, median age was 67 years, and anti-HBs was >10 IU/mL in 72%. The immunosuppressive drug most used was tocilizumab (72%). Despite HBV prophylaxis recommendation, 38 (62%) patients received entecavir and 23 (38%) did not. Baseline features of both groups were similar. At follow-up, we found no cases of HBsAg seroreversion and only 2 (3%) patients (no prophylaxis group) had detectable serum HBV-DNA (<15 IU/mL). Both were anti-HBs negative and had normal aminotransferase levels. Our data show that the risk of HBV reactivation in patients with severe COVID-19 and resolved HBV infection undergoing immunosuppressive treatment is low. However, if a systematic follow-up after hospital discharge is unfeasible in patients without anti-HBs, a short course of antiviral prophylaxis may be a safe option.

BACKGROUND & AIMS: Complications of cirrhosis are the main cause of hospital admissions in liver units. In areas where HCV is prevalent, most of these admissions are attributable to HCV-related cirrhosis (HCV-cirrhosis). This study assessed the impact of direct-acting antivirals (DAA) in the profile of patients with liver disease admitted to a referral liver unit from a university hospital. METHODS: We registered hospital admissions resulting from cirrhosis to the Liver Unit of the Hospital Clinic of Barcelona, from 2011 to 2014 (pre-DAA period) and from 2015 to 2019 (post-DAA period). RESULTS: From a total of 14,865 hospital admissions, 10,053 resulted from cirrhosis (corresponding to 6,272 patients). The number and proportion of hospital admissions because of HCV-cirrhosis remained stable during the period 2011-2014 (525 per year, 48.8% of the total), but decreased progressively after 2015 (p <0.001), reaching <300 (27.1%) admissions in 2019. Similarly, HCV-cirrhosis accounted for 3,885 inpatient days per year (44.9%) during the pre-DAA period and decreased steadily after 2015 (p >0.001), reaching only 1,909 inpatient days (22%) in 2019. The figures for intensive care unit admissions followed a similar pattern. By means of a slope analysis (binomial regression model), we predicted that HCV-cirrhosis hospital admissions will be residual by 2025 (2.3%, 95% CI 0-10.9%). By contrast, we observed a significant increase in hospital admissions because of metabolic-associated fatty liver disease (5-fold) and autoimmune hepatitis (4-fold) during the study period. CONCLUSIONS: In summary, our data showed a profound reduction in HCV-cirrhosis hospitalisation burden since 2015, coincident with the wide use of DAAs in Spain. Our predictions suggest that, by 2025, HCV-cirrhosis will be a marginal cause of hospital admissions for patients with liver disease. LAY SUMMARY: Over the past few years, the wide use of antiviral drugs that cure HCV has had a significant effect on patients being admitted to hospital. Most patients with HCV and cirrhosis are treated (and often cured) in the community and, thus, the number of hospital admissions because of severe forms of HCV has decreased drastically. HCV is no longer the first cause of admission into liver units and, in only a few years from now, it is likely to be only a residual cause of hospitalisation.

BACKGROUND & AIMS: It is important to know which patients with hepatitis C are likely to develop liver-related complications after achieving a sustained virological response (SVR) to direct-acting antiviral (DAA) therapy. We aimed to describe the incidence of liver-related events in a population of patients with HCV-associated compensated advanced chronic liver disease (cACLD) who achieved SVR and to identify non-invasive parameters that predict the occurrence of liver-related events. METHODS: This 2-center prospective study included 572 patients with cACLD who had been treated with DAAs and had achieved SVR. Patients had liver stiffness measurement (LSM) ≥10 kPa at baseline and had never decompensated (Child-Pugh class A). Laboratory work-up and LSM were performed at baseline and at 1 year of follow-up. RESULTS: The median follow-up was 2.8 years during which 32 patients (5.6%) presented with a liver-related event. The incidence rate (IR) of portal hypertension-related decompensation was 0.34/100 patient-years. These patients all had baseline LSM >20 kPa, and LSM did not improve during follow-up in 4 out of 5 of them. Hepatocellular carcinoma (HCC) occurred in 25 patients (IR 1.5/100 patient-years). Albumin levels at follow-up (hazard ratio [HR] 0.08; 95% CI 0.02-0.25) and LSM <10 kPa at follow-up (HR 0.33; 95% CI 0.11-0.96) were independently associated with the risk of HCC. Combining both predictors identified 2 groups with differing risk of HCC occurrence: those with LSM ≥20 kPa at follow-up or those with LSM between 10-20 kPa and albumin levels <4.4 g/dl were at the highest risk (IR ≥1.9/100 patient-years). Visual nomograms predicting HCC risk based on LSM and albumin at 1 year of follow-up were constructed. CONCLUSION: In patients with HCV-related cACLD who have achieved SVR with DAAs, HCC is the most frequent liver-related event. Both albumin levels and LSM are useful for stratifying patients based on their risk of developing HCC during follow-up. LAY SUMMARY: New oral antivirals can cure chronic hepatitis C infection, however patients with advanced chronic liver disease are still at risk of presenting with liver-related complications. The most frequent complication after oral antiviral therapy in asymptomatic patients with advanced chronic liver disease was liver cancer. The use of simple parameters such liver stiffness and albumin levels after treatment can help to identify patients at higher or lower risk of liver cancer.

BACKGROUND & AIMS: Clinically significant portal hypertension (CSPH), defined as a hepatic venous pressure gradient (HVPG) ≥10 mmHg, persists 24 weeks after sustained virological response (SVR) in up to 78% of patients with HCV-related cirrhosis treated with direct-acting antivirals. These patients remain at risk of decompensation. However, long-term paired clinical and hemodynamic data are not available for this population. METHODS: We conducted a prospective multicenter study in 226 patients with HCV-related cirrhosis and CSPH who achieved SVR after antiviral therapy. Patients with CSPH 24 weeks after end of treatment (SVR24) were offered another hemodynamic assessment 96 weeks after end of treatment (SVR96). RESULTS: All patients were clinically evaluated. Out of 176 patients with CSPH at SVR24, 117 (66%) underwent an HVPG measurement at SVR96. At SVR96, 55/117 (47%) patients had HVPG <10 mmHg and 53% had CSPH (65% if we assume persistence of CSPH in all 59 non-evaluated patients). The proportion of high-risk patients (HVPG ≥16 mmHg) diminished from 41% to 15%. Liver stiffness decreased markedly after SVR (median decrease 10.5 ± 13 kPa) but did not correlate with HVPG changes (30% of patients with liver stiffness measurement <13.6 kPa still had CSPH). Seventeen (7%) patients presented with de novo/additional clinical decompensation, which was independently associated with baseline HVPG ≥16 mmHg and history of ascites. CONCLUSIONS: Patients achieving SVR experienced a progressive reduction in portal pressure during follow-up. However, CSPH may persist in up to 53-65% of patients at SVR96, indicating persistent risk of decompensation. History of ascites and high-risk HVPG values identified patients at higher risk of de novo or further clinical decompensation. LAY SUMMARY: As a major complication of cirrhosis, clinically significant portal hypertension (CSPH) is associated with adverse clinical outcomes. Herein, we show that CSPH persists at 96 weeks in just over half of patients with HCV-related cirrhosis, despite HCV elimination by direct-acting antivirals. Despite viral cure, patients with CSPH at the start of antiviral treatment remain at long-term risk of hepatic complications and should be managed accordingly.

Chronic hepatitis C virus (HCV) infection impairs HCV CD8+ T-cell responses, while it could influence immune responses towards unrelated viruses/vaccines (e.g. cytomegalovirus, CMV, and influenza, Flu). The aim of our study was to delineate whether restoration of these virus-specific CD8+ T cells occurs after direct-acting antiviral (DAA) therapies and particularly in patients with cirrhosis. We performed longitudinal analysis (baseline, week 4, follow-up [FU] 12 and FU48) of virus-specific CD8+ T cells by multicolour flow cytometry in HCV-cirrhotic patients undergoing DAA therapy (n = 26) after in vitro expansion with immunodominant HCV, CMV and Flu epitopes restricted by HLA-A*02. HCV noncirrhotic patients (n = 9) and healthy individuals (n = 10) served as controls. We found that the proliferative capacity of HCV-specific CD8+ T cells increased from baseline up to FU48 in a significant proportion of cirrhotic and noncirrhotic patients. Nevertheless, these cells remained poor cytokine producers in both patient groups, regardless of the down-regulation of inhibitory co-regulatory receptors in HCV-cirrhotic patients at FU48. Likewise, high expression levels of these exhaustion markers were detected in CMV-/Flu-specific CD8+ T cells in HCV-cirrhotic patients at all time points, albeit without affecting their proliferative capacity or cytokine production. We conclude that DAA therapies induce restoration of the proliferative capacity of HCV-specific CD8+ T cells. However, these cells remain phenotypically and functionally impaired. Contrarily, the 'exhausted' phenotype in CMV-/Flu-specific CD8+ T cells in HCV-cirrhotic patients did not associate with their functions. Larger studier with longer follow-up may elucidate whether this complex interplay influences the outcome of cirrhotic patients.

Hepatitis E virus (HEV) and hepatitis A virus (HAV) are both secreted in feces. Despite HEV transmission in Europe is mainly zoonotic, person-to-person transmission has not been completely excluded. Men who have sex with men (MSM) constitute a high-risk group for HAV mostly due to oral sex. We investigated the potential transmission of HEV during an acute hepatitis A (AHA) outbreak mainly affecting MSM. One hundred and two patients were diagnosed with AHA. Sixty-nine (68%) self-reported to be MSM, 75% of whom had high-risk sexual behaviors and 46% had suffered previous sexually transmitted diseases. We collected serum from 85 (83%) patients during AHA. HEV-IgG seroprevalence was not different among MSM (7%) compared with non-MSM (8%) patients. Two patients had positive anti-HEV-IgM, but all samples tested negative for HEV-RNA. These results suggest that HEV does not spread by sexual contact or person-to-person in our area.

BACKGROUND AND AIMS: Recent studies have found an increase in the seroprevalence of hepatitis E virus (HEV) infection in patients with autoimmune hepatitis (AIH). We aimed to assess the prevalence of positive anti-HEV IgM and IgG, and HEV-RNA in a cohort of patients with AIH, to determine the impact of positive HEV serology on patient outcome, and to evaluate the role of hypergammaglobulinemia and positive autoantibodies in the presence of positive anti-HEV serology. METHODS: One hundred and five patients tested for HEV infection between 2014 and 2018 were included in the study: 50 with chronic AIH (more than 1 year on treatment), and 55 with an acute hepatitis (30 patients with acute AIH and 25 with non-AIH). RESULTS: Seroprevalence of HEV was higher in patients with acute AIH (17% vs 10% in patients with chronic AIH and 8% in patients with non-AIH). Patients with acute AIH and positive anti-HEV IgG were older (58 vs 40; P = .006), had higher IgG levels (27 g/dL vs 13 g/dL; P = .03) and antismooth muscle antibodies (ASMA) titres (1:160 vs 1:80; P = .045), and were more likely to have another autoimmune disease (60% vs 16%; P = .03). At the time of HEV testing, anti-HEV IgG positive patients had significantly higher serum IgG levels (17 g/L vs 11 g/L; P = .009), ANA (1:160 vs 1:60; P = .026) and ASMA titres (1:80 vs 1:40; P = .021). CONCLUSION: Seroprevalence of HEV in patients with AIH in Catalonia does not differ from that of the general population. The higher HEV seroprevalence in patients with acute AIH with higher levels of gammaglobulins and high antibody titres suggest the presence of cross-reactivity between HEV and liver antigens.

Despite rarely assessed, sexuality is a relevant domain in Quality of Life. We prospectively evaluated the impact of direct-acting antiviral therapy on sexuality in a cohort of 186 patients with chronic hepatitis C (HCV). Sexual dysfunction was assessed by validated scales CSFQ-14/CSFQ-VAS at baseline and one year after treatment finalization. Median age was 55 years and 87% had mild liver disease. Basal prevalence of sexual dysfunction (62%) and fear of HCV transmission (25%) were high. After HCV cure, both sexual dysfunction prevalence and CSFQ-VAS improved (P = .058 and P < .01, respectively), and fear of HCV transmission dropped to 16% (P = .02). These changes were especially relevant in young men (<55), where sexual dysfunction decreased from 48.6% to 29.7% (P = .04) and among non-depressed patients in whom sexual dysfunction decreased from 54.6% to 47% (P < .01). Age and major depression remained as independent factors of sexual dysfunction persistence after HCV cure. Our data suggest that HCV eradication is associated with an improvement in sexuality, in those patients without depression.

BACKGROUND AND AIM: Accurate information on the epidemiology of hepatitis C and B infection is mandatory to establish a national/regional plan. We aim to update the prevalence of hepatitis C and B infection in Catalonia using point-of-care tests to analyze the risk factors related and to implement a linkage-to-care circuit. METHODS: This is a community-based study. A random list of adult individuals was retrieved from censuses of primary care centers. Point-of-care tests for anti-hepatitis C virus (HCV) and HBV surface antigen (HBsAg) and a questionnaire for risk factor assessment were performed. Positive results were validated and a circuit for linkage-to-care was established. RESULTS: A total of 3328 individuals were included. The anti-HCV and HBsAg overall prevalence were lower than expected [1.02%, 95% confidence interval (CI) 0.65-1.39; and 0.52%, 95% CI 0.26-0.77, respectively]. Anti-HCV positive subjects were mostly (88%) autochthonous. The prevalence increased with age; only 12% were under age 40. The associated risk factors were drug use, blood transfusion, relative with HCV, and diabetes. Notably, the prevalence of active infection was only 0.49% (95% CI 0.23-0.74), 40% less than previously reported, reflecting the impact of direct acting antiviral therapy. Differently, HBsAg positive subjects were mostly foreign migrants (53%) with no other risk factors. Despite the implementation of a linkage-to-care circuit, one third of HBsAg positive subjects were lost. CONCLUSIONS: The prevalence of HCV infection was lower than previously reported, showing a strong impact of direct acting antiviral therapy in the last years. Because of hepatitis B universal vaccination, HBV infection in Catalonia is mainly associated with migrant population. Linkage-to-care in patients with hepatitis B was challenging and warrants additional efforts.
