RESUMEN

BACKGROUND AND AIMS: Since the introduction of SARS-CoV-2 vaccines, several cases of vaccine-induced immune thrombocytopenia and thrombosis (VITT) have been described, especially cerebral vein thrombosis. We aimed to retrospectively collect all new cases of acute onset first or recurrent splanchnic vein thrombosis (SVT) following a recent SARS-CoV-2 vaccination within the Vascular Liver Disease Group network. APPROACH AND RESULTS: New cases of SVT were identified from April 2021 to April 2022; follow-up was completed on December 31, 2022. Criteria to define VITT were derived from previous studies. Data from a pre-COVID cohort of patients with SVT (N=436) were used for comparison of clinical presentation, etiology, and outcome. Twenty-nine patients were identified with SVT occurring with a median of 11 days (range 2-76) after the first (48%), second (41%), or third (10%) vaccination (ChAdOx1 nCov-19 (n=12) or BNT162b2 (n=14), other (n=3) Only 2 patients(7%) fulfilled criteria for definite VITT. Twenty (69%) had SVT at multiple sites, including 4 (14%) with concomitant extra-abdominal thrombosis. Only 28% had an underlying prothrombotic condition, compared to 52% in the pre-COVID SVT cohort ( p =0.01). Five patients (17%) underwent bowel resection for mesenteric ischemia, compared with 3% in pre-COVID SVT ( p <0.001). Two patients died shortly after diagnosis (7%). CONCLUSIONS: Although definite VITT was rare, in 72% of cases, no other cause for SVT could be identified following SARS-CoV-2 vaccination. These cases were different from patients with nonvaccine-related SVT, with lower incidence of prothrombotic conditions, higher rates of bowel ischemia, and poorer outcome. Although SVT after SARS-CoV-2 vaccination is rare in absolute terms, these data remain relevant considering ongoing revaccination programs.

RESUMEN

Background & Aims: Porto-sinusoidal vascular disorder (PSVD) encompasses a group of liver diseases with vascular abnormalities that can cause portal hypertension in the absence of cirrhosis. The new diagnostic criteria allow for coexistence with other liver diseases, however its relationship with chronic hepatitis B (CHB) remains unclear. This study aimed to assess HBV prevalence in a PSVD cohort and evaluate its clinical impact. Methods: This retrospective study was conducted on patients with PSVD at Hospital Clínic Barcelona. HBV serology was evaluated, and patients were categorized into HBV chronic infection, past infection, or no HBV exposure. Clinical characteristics and outcomes were compared. Results: We included 155 patients with PSVD. Prevalence of CHB and past HBV infection in patients with PSVD was higher than in the general population (5.8% vs. 0.5%, p <0.0001 and 20% vs. 9.1%, p <0.0001, respectively). Patients with CHB had a significant delay in PSVD diagnosis compared to those without CHB (11 [5-25] vs. 1 [0-3] years, p = 0.002) and had a more advanced disease (MELD score 12 [9-17] vs. 9 [7-11], p = 0.012) at the time of PSVD diagnosis. The clinical evolution of PSVD in patients with CHB was marked by a significantly higher transplantation rate at the last follow-up (33% vs. 4.1%, p = 0.001). Conclusions: Recognizing the coexistence of PSVD and CHB is important for timely diagnosis and optimal management, highlighting the potential benefits of specialized care for potentially improved outcomes. Impact and implications: The new diagnostic criteria for porto-sinusoidal vascular disorder (PSVD) allow for coexistence with other liver diseases. The results of the present study highlight, for the first time, a non-negligible prevalence of chronic hepatitis B in the PSVD population that was previously unknown. Coexistence may challenge and delay the PSVD diagnosis and is associated with a more unfavorable clinical course. Our findings will increase awareness of this coexistence and improve PSVD diagnosis and management. Furthermore, the data will encourage new studies to determine the prevalence and clinical behavior of other chronic liver diseases that coexist with PSVD.

RESUMEN

To elucidate the role of splanchnic vein thrombosis (SVT) and genomic characteristics in prognosis and survival, we compared patients with polycythemia vera (PV) or essential thrombocythemia (ET) presenting SVT at diagnosis (n = 69, median age 43 years) or during follow-up (n = 21, median age 46 years) to a sex- and age-matched control group of PV/ET without SVT (n = 165, median age 48 years). The majority of patients presenting with SVT at diagnosis were classified as myeloproliferative neoplasm with heterozygous JAK2 mutation (87% of cases vs. 69% in PV/ET control group, p < 0.05), characterized by low JAK2 allele burden and no high-risk mutations. Despite this lower molecular complexity, patients presenting with SVT showed a higher risk of death (HR 3.0, 95% CI 1.5-6.0, p = 0.003) and lower event-free survival (HR 3.0, 95% CI 1.9-4.8, p < 0.001) than age- and sex-matched PV/ET controls. In patients presenting with SVT, molecular high-risk was associated with increased risk of venous re-thrombosis (HR 5.8, 95% CI 1.4-24.0, p = 0.01). Patients developing SVT during follow-up were more frequently allocated in molecular high-risk than those with SVT at diagnosis (52% versus 13%, p < 0.05). In the whole cohort of patients, molecular classification identified PV/ET patients at higher risk of disease progression whereas DNMT3A/TET2/ASXL1 mutations were associated with higher risk of arterial thrombosis. In conclusion, clinical and molecular characteristics are different in PV/ET patients with SVT, depending on whether it occurs at diagnosis or at follow-up. Molecular characterization by NGS is useful for assessing the risk of thrombosis and disease progression in young patients with PV/ET.

RESUMEN

BACKGROUND & AIMS: Comparative assessments of immunogenicity following different COVID-19 vaccines in patients with distinct liver diseases are lacking. SARS-CoV-2-specific T-cell and antibody responses were evaluated longitudinally after one to three vaccine doses, with long-term follow-up for COVID-19-related clinical outcomes. METHODS: A total of 849 participants (355 with cirrhosis, 74 with autoimmune hepatitis [AIH], 36 with vascular liver disease [VLD], 257 liver transplant recipients [LTRs] and 127 healthy controls [HCs]) were recruited from four countries. Standardised immune assays were performed pre and post three vaccine doses (V1-3). RESULTS: In the total cohort, there were incremental increases in antibody titres after each vaccine dose (p <0.0001). Factors associated with reduced antibody responses were age and LT, whereas heterologous vaccination, prior COVID-19 and mRNA platforms were associated with greater responses. Although antibody titres decreased between post-V2 and pre-V3 (p = 0.012), patients with AIH, VLD, and cirrhosis had equivalent antibody responses to HCs post-V3. LTRs had lower and more heterogenous antibody titres than other groups, including post-V3 where 9% had no detectable antibodies; this was heavily influenced by intensity of immunosuppression. Vaccination increased T-cell IFNγ responses in all groups except LTRs. Patients with liver disease had lower functional antibody responses against nine Omicron subvariants and reduced T-cell responses to Omicron BA.1-specific peptides compared to wild-type. 122 cases of breakthrough COVID-19 were reported of which 5/122 (4%) were severe. Of the severe cases, 4/5 (80%) occurred in LTRs and 2/5 (40%) had no serological response post-V2. CONCLUSION: After three COVID-19 vaccines, patients with liver disease generally develop robust antibody and T-cell responses to vaccination and have mild COVID-19. However, LTRs have sustained no/low antibody titres and appear most vulnerable to severe disease. IMPACT AND IMPLICATIONS: Standardised assessments of the immune response to different COVID-19 vaccines in patients with liver disease are lacking. We performed antibody and T-cell assays at multiple timepoints following up to three vaccine doses in a large cohort of patients with a range of liver conditions. Overall, the three most widely available vaccine platforms were immunogenic and appeared to protect against severe breakthrough COVID-19. This will provide reassurance to patients with chronic liver disease who were deemed at high risk of severe COVID-19 during the pre-vaccination era, however, liver transplant recipients had the lowest antibody titres and remained vulnerable to severe breakthrough infection. We also characterise the immune response to multiple SARS-CoV-2 variants and describe the interaction between disease type, severity, and vaccine platform. These insights may prove useful in the event of future viral infections which also require rapid vaccine development and delivery to patients with liver disease.

RESUMEN

Over the past decade, significant advancements in pharmacological, endoscopic, and radiographic treatments have emerged in the management of patients with cirrhosis and esophagogastric varices or variceal hemorrhage. These advances have been in several areas, including the role of screening and primary prophylaxis (preventing an initial variceal bleed), evaluation and management of acute esophagogastric variceal hemorrhage, and in preventing variceal rebleeding. Therefore, we believe there is a need for an updated, evidence-based "narrative review" on this important clinical topic that will be relevant for internists, hospitalists, intensive care unit physicians, and those in training. We believe the guidance presented in this narrative review will enhance daily medical practice of health care professionals and has the potential to improve quality of care for these complex patients.

RESUMEN

Fontan-type surgery is the final step in the sequential palliative surgical treatment of infants born with a univentricular heart. The resulting long-term haemodynamic changes promote liver damage, leading to Fontan-associated liver disease (FALD), in virtually all patients with Fontan circulation. Owing to the lack of a uniform definition of FALD and the competitive risk of other complications developed by Fontan patients, the impact of FALD on the prognosis of these patients is currently debatable. However, based on the increasing number of adult Fontan patients and recent research interest, the European Association for The Study of the Liver and the European Reference Network on Rare Liver Diseases thought a position paper timely. The aims of the current paper are: (1) to provide a clear definition and description of FALD, including clinical, analytical, radiological, haemodynamic, and histological features; (2) to facilitate guidance for staging the liver disease; and (3) to provide evidence- and experience-based recommendations for the management of different clinical scenarios.

RESUMEN

BACKGROUND AND AIMS: A reduction in hepatic venous pressure gradient (HVPG) is the most accurate marker for assessing the severity of portal hypertension and the effectiveness of intervention treatments. This study aimed to evaluate the prognostic potential of blood-based proteomic biomarkers in predicting HVPG response amongst cirrhotic patients with portal hypertension due to Hepatitis C virus (HCV) and had achieved sustained virologic response (SVR). METHODS: The study comprised 59 patients from two cohorts. Patients underwent paired HVPG (pretreatment and after SVR), liver stiffness (LSM), and enhanced liver fibrosis scores (ELF) measurements, as well as proteomics-based profiling on serum samples using SomaScan® at baseline (BL) and after SVR (EOS). Machine learning with feature selection (Caret, Random Forest and RPART) methods were performed to determine the proteins capable of classifying HVPG responders. Model performance was evaluated using AUROC (pROC R package). RESULTS: Patients were stratified by a change in HVPG (EOS vs. BL) into responders (greater than 20% decline in HVPG from BL, or <10 mmHg at EOS with >10 mmHg at BL) and non-responders. LSM and ELF decreased markedly after SVR but did not correlate with HVPG response. SomaScan (SomaLogic, Inc., Boulder, CO) analysis revealed a substantial shift in the peripheral proteome composition, reflected by 82 significantly differentially abundant proteins. Twelve proteins accurately distinguished responders from non-responders, with an AUROC of .86, sensitivity of 83%, specificity of 83%, accuracy of 83%, PPV of 83%, and NPV of 83%. CONCLUSIONS: A combined non-invasive soluble protein signature was identified, capable of accurately predicting HVPG response in HCV liver cirrhosis patients after achieving SVR.

RESUMEN

Historically, anticoagulants were contraindicated in patients with cirrhosis owing to concerns about bleeding risks. However, recent studies have shown that patients with cirrhosis are not naturally anticoagulated and are at increased risk of prothrombotic events, such as portal venous thrombosis. In this article, we review preclinical and clinical data on the effects of anticoagulants in cirrhosis, including their potential benefits in reducing liver fibrosis, portal hypertension, and improving survival. Despite promising preclinical evidence, clinical translation has proven challenging. Nevertheless, we discuss the use of anticoagulation in specific clinical scenarios, such as patients with atrial fibrillation and portal vein thrombosis, and highlight the need for further research, including randomised-controlled trials, to determine the optimal role of anticoagulants in the management of patients with cirrhosis.

RESUMEN

BACKGROUND & AIMS: Further decompensation represents a prognostic stage of cirrhosis associated with higher mortality compared with first decompensation. A transjugular intrahepatic portosystemic shunt (TIPS) is indicated to prevent variceal rebleeding and for refractory ascites, but its overall efficacy to prevent further decompensations is unknown. This study assessed the incidence of further decompensation and mortality after TIPS vs. standard of care (SOC). METHODS: Controlled studies assessing covered TIPS compared with SOC for the indication of refractory ascites and prevention of variceal rebleeding published from 2004 to 2020 were considered. We collected individual patient data (IPD) to perform an IPD meta-analysis and to compare the treatment effect in a propensity score (PS)-matched population. Primary outcome was the incidence of further decompensation and the secondary outcome was overall survival. RESULTS: In total, 3,949 individual patient data sets were extracted from 12 controlled studies and, after PS matching, 2,338 patients with similar characteristics (SOC = 1,749; TIPS = 589) were analysed. The 2-year cumulative incidence function of further decompensation in the PS-matched population was 0.48 (95% CI 0.43-0.52) in the TIPS group vs. 0.63 (95% CI 0.61-0.65) in the SOC group (stratified Gray's test, p <0.0001), considering mortality and liver transplantation as competing events. The lower further decompensation rate with TIPS was confirmed by adjusted IPD meta-analysis (hazard ratio 0.44; 95% CI 0.37-0.54) and was consistent across TIPS indication subgroups. The 2-year cumulative survival probability was higher with TIPS than with SOC (0.71 vs. 0.63; p = 0.0001). CONCLUSIONS: The use of TIPS for refractory ascites and for prevention of variceal rebleeding reduces the incidence of a further decompensation event compared with SOC and increases survival in highly selected patients. IMPACT AND IMPLICATIONS: A further decompensation (new or worsening ascites, variceal bleeding or rebleeding, hepatic encephalopathy, jaundice, hepatorenal syndrome-acute kidney injury and spontaneous bacterial peritonitis) in patients with cirrhosis is associated with a poor prognosis. Besides the known role of TIPS in portal hypertension-related complications, this study shows that TIPS is also able to decrease the overall risk of a further decompensation and increase survival compared with standard of care. These results further support the role of TIPS in the management of patients with cirrhosis and portal hypertension-related complications.

RESUMEN

BACKGROUND: The clinical relevance and management of incidental splanchnic vein thrombosis (SVT) remain poorly defined. OBJECTIVES: The objectives of this study were to evaluate the clinical course of incidental SVT in comparison with symptomatic SVT and assess the safety and effectiveness of anticoagulant treatment in incidental SVT. METHODS: Individual patient data meta-analysis of randomized controlled trials or prospective studies published up to June 2021. Efficacy outcomes were recurrent venous thromboembolism (VTE) and all-cause mortality. The safety outcome was major bleeding. Incidence rate ratios and 95% CIs for incidental vs symptomatic SVT were estimated before and after propensity-score matching. Multivariable Cox models were used considering anticoagulant treatment as a time-varying covariate. RESULTS: In total, 493 patients with incidental SVT and 493 propensity-matched patients with symptomatic SVT were analyzed. Patients with incidental SVT were less likely to receive anticoagulant treatment (72.4% vs 83.6%). Incidence rate ratios (95% CI) for major bleeding, recurrent VTE, and all-cause mortality in patients with incidental SVT compared with symptomatic SVT were 1.3 (0.8, 2.2), 2.0 (1.2, 3.3), and 0.5 (0.4, 0.7), respectively. In patients with incidental SVT, anticoagulant therapy was associated with a lower risk of major bleeding (hazard ratio [HR] 0.41; 95% CI, 0.21 to 0.71), recurrent VTE (HR 0.33; 95% CI, 0.18 to 0.61), and all-cause mortality (HR 0.23; 95% CI, 0.15 to 0.35). CONCLUSION: Patients with incidental SVT appeared to have a similar risk of major bleeding, a higher risk of recurrent thrombosis, but lower all-cause mortality than patients with symptomatic SVT. Anticoagulant therapy seemed safe and effective in patients with incidental SVT.

RESUMEN

BACKGROUND & AIMS: Clinical guidelines do not recommend long-term anticoagulation in non-cirrhotic splanchnic vein thrombosis (NC-SVT) without underlying thrombophilia because it is assumed that there is a very low risk of recurrent thrombosis (RT). Our first aim was to describe the incidence of RT in people with NC-SVT without an indication for long-term anticoagulation. The second aim was to identify RT risk factors and afterwards verify them in a validation cohort. METHODS: This is a multicentre, retrospective observational study evaluating risk factors for RT in 64 people with NC-SVT of idiopathic/local factor aetiology. In a subgroup of 48 individuals, the potential value of additional thrombophilic parameters to predict RT was analysed. Findings were validated in 70 individuals with idiopathic/local factor NC-SVT. RESULTS: Of the 64 participants in the training cohort, 17 (26%) presented splanchnic and/or extrasplanchnic RT (overall-RT) during follow-up (cumulative incidence: 2, 10, 19, and 34% at 1, 2, 5, and 10 years, respectively). In addition, 53% of people with splanchnic RT were asymptomatic. No clinical or biochemical parameters predicted overall-RT. However, in the 48 people with an additional comprehensive thrombophilic study, factor VIII ≥150% was the only independent factor predicting overall-RT (hazard ratio 7.10, 95% CI 2.17-23.17, p <0.01). In the validation cohort, 19 individuals (27%) presented overall-RT, and it was also independently predicted by factor VIII >150% (hazard ratio 3.71, 95% CI 1.31-10.5, p <0.01). The predictive value of factor VIII was confirmed in both people with idiopathic/local factor aetiology associated NC-SVT. CONCLUSIONS: People with idiopathic/local factor NC-SVT are at risk of overall-RT. Splanchnic RT can be asymptomatic and requires screening for its detection. Values of factor VIII ≥150% may help identify individuals at high risk of overall-RT who could benefit from long-term anticoagulation. IMPACT AND IMPLICATIONS: People with idiopathic/isolated local factor non-cirrhotic portal vein thrombosis were previously thought to be at minimal risk of re-thrombosis and therefore did not receive scheduled follow-up. The results of this study are of special interest for hepatologists treating people with non-cirrhotic splanchnic thrombosis, as they show a 25% incidence of re-thrombosis and support the close follow-up of people with factor VIII >150% to ensure the early identification of new thrombotic events.

RESUMEN

BACKGROUND & AIMS: In individuals with compensated advanced chronic liver disease (cACLD), the severity of portal hypertension (PH) determines the risk of decompensation. Invasive measurement of the hepatic venous pressure gradient (HVPG) is the diagnostic gold standard for PH. We evaluated the utility of machine learning models (MLMs) based on standard laboratory parameters to predict the severity of PH in individuals with cACLD. METHODS: A detailed laboratory workup of individuals with cACLD recruited from the Vienna cohort (NCT03267615) was utilised to predict clinically significant portal hypertension (CSPH, i.e., HVPG ≥10 mmHg) and severe PH (i.e., HVPG ≥16 mmHg). The MLMs were then evaluated in individual external datasets and optimised in the merged cohort. RESULTS: Among 1,232 participants with cACLD, the prevalence of CSPH/severe PH was similar in the Vienna (n = 163, 67.4%/35.0%) and validation (n = 1,069, 70.3%/34.7%) cohorts. The MLMs were based on 3 (3P: platelet count, bilirubin, international normalised ratio) or 5 (5P: +cholinesterase, +gamma-glutamyl transferase, +activated partial thromboplastin time replacing international normalised ratio) laboratory parameters. The MLMs performed robustly in the Vienna cohort. 5P-MLM had the best AUCs for CSPH (0.813) and severe PH (0.887) and compared favourably to liver stiffness measurement (AUC: 0.808). Their performance in external validation datasets was heterogeneous (AUCs: 0.589-0.887). Training on the merged cohort optimised model performance for CSPH (AUCs for 3P and 5P: 0.775 and 0.789, respectively) and severe PH (0.737 and 0.828, respectively). CONCLUSIONS: Internally trained MLMs reliably predicted PH severity in the Vienna cACLD cohort but exhibited heterogeneous results on external validation. The proposed 3P/5P online tool can reliably identify individuals with CSPH or severe PH, who are thus at risk of hepatic decompensation. IMPACT AND IMPLICATIONS: We used machine learning models based on widely available laboratory parameters to develop a non-invasive model to predict the severity of portal hypertension in individuals with compensated cirrhosis, who currently require invasive measurement of hepatic venous pressure gradient. We validated our findings in a large multicentre cohort of individuals with advanced chronic liver disease (cACLD) of any cause. Finally, we provide a readily available online calculator, based on 3 (platelet count, bilirubin, international normalised ratio) or 5 (platelet count, bilirubin, activated partial thromboplastin time, gamma-glutamyltransferase, choline-esterase) widely available laboratory parameters, that clinicians can use to predict the likelihood of their patients with cACLD having clinically significant or severe portal hypertension.

RESUMEN

The hepatic venous pressure gradient (HVPG) is currently considered the gold standard to assess portal hypertension (PH) in patients with cirrhosis. A meticulous technique is important to achieve accurate and reproducible results, and values obtained during measurement are applied in risk stratification of patients with PH, allocating treatment options, monitoring follow-up, and deciding management options in surgical patients. The use of portosystemic pressure gradients in patients undergoing placement of transjugular intrahepatic portosystemic shunts has been studied extensively and has great influence on decisions on shunt diameter. The purpose of this study was to describe the recommended technique to measure HVPG and portosystemic pressure gradient and to review the existing literature describing the importance of these hemodynamic measurements in clinical practice.

RESUMEN

1: ESGE recommends that patients with compensated advanced chronic liver disease (ACLD; due to viruses, alcohol, and/or nonobese [BMI < 30 kg/m2] nonalcoholic steatohepatitis) and clinically significant portal hypertension (hepatic venous pressure gradient [HVPG] > 10 mmHg and/or liver stiffness by transient elastography > 25 kPa) should receive, if no contraindications, nonselective beta blocker (NSBB) therapy (preferably carvedilol) to prevent the development of variceal bleeding.Strong recommendation, moderate quality evidence. 2: ESGE recommends that in those patients unable to receive NSBB therapy with a screening upper gastrointestinal (GI) endoscopy that demonstrates high risk esophageal varices, endoscopic band ligation (EBL) is the endoscopic prophylactic treatment of choice.

RESUMEN

BACKGROUND & AIMS: Non-invasive tests (NITs) for clinically significant portal hypertension (CSPH; hepatic venous pressure gradient [HVPG] ≥10 mmHg) have predominantly been studied in patients with active HCV infection. Investigations after HCV cure are limited and have yielded conflicting results. We conducted a pooled analysis to determine the diagnostic/prognostic utility of liver stiffness measurement (LSM)/platelet count (PLT) in this setting. METHODS: A total of 418 patients with pre-treatment HVPG ≥6 mmHg who achieved sustained virological response (SVR) and underwent post-treatment HVPG measurement were assessed, of whom 324 (HVPG/NIT-cohort) also had paired data on pre-/post-treatment LSM/PLT. The derived LSM/PLT criteria were then validated against the direct endpoint decompensation in 755 patients with compensated advanced chronic liver disease (cACLD) with SVR (cACLD-validation-cohort). RESULTS: HVPG/NIT-cohort: Among patients with cACLD, the pre-/post-treatment prevalence of CSPH was 80%/54%. The correlation between LSM/HVPG increased from pre- to post-treatment (r = 0.45 vs. 0.60), while that of PLT/HVPG remained unchanged. For given LSM/PLT values, HVPG tended to be lower post- vs. pre-treatment, indicating the need for dedicated algorithms. Combining post-treatment LSM/PLT yielded a high diagnostic accuracy for post-treatment CSPH in cACLD (AUC 0.884; 95% CI 0.843-0.926). Post-treatment LSM <12 kPa & PLT >150 G/L excluded CSPH (sensitivity: 99.2%), while LSM ≥25 kPa was highly specific for CSPH (93.6%). cACLD-validation-cohort: the 3-year decompensation risk was 0% in the 42.5% of patients who met the LSM <12 kPa & PLT >150 G/L criteria. In patients with post-treatment LSM ≥25 kPa (prevalence: 16.8%), the 3-year decompensation risk was 9.6%, while it was 1.3% in those meeting none of the above criteria (prevalence: 40.7%). CONCLUSIONS: NITs can estimate the probability of CSPH after HCV cure and predict clinical outcomes. Patients with cACLD but LSM <12 kPa & PLT>150 G/L may be discharged from portal hypertension surveillance if no co-factors are present, while patients with LSM ≥25 kPa require surveillance/treatment. LAY SUMMARY: Measurement of liver stiffness by a specific ultrasound device and platelet count (a simple blood test) are broadly used for the non-invasive diagnosis of increased blood pressure in the veins leading to the liver, which drives the development of complications in patients with advanced liver disease. The results of our pooled analysis refute previous concerns that these tests are less accurate after the cure of hepatitis C virus (HCV) infection. We have developed diagnostic criteria that facilitate personalized management after HCV cure and allow for a de-escalation of care in a high proportion of patients, thereby decreasing disease burden.
