RESUMEN

The hepatitis C virus (HCV), a single-stranded RNA virus belonging to the Flaviviridae family, is a major cause of hepatocellular carcinoma (HCC) worldwide. Tumors caused by HCC have an increased mortality rate globally, which is more accentuated in Western countries. The carcinogenic potential of this virus is mediated through a wide range of mechanisms, spanning from the induction of chronic inflammation to oxidative stress and deregulation of cellular pathways by viral proteins. As the number of new infections continues unabated, HCC-related mortality should be prioritized through early detection, continued prevention of HCV transmission, and treatment of HCV with safe and efficacious direct antiviral agents (DAAs). People who inject drugs (PWID) are a significant reservoir of new HCV infections globally, and in order to eliminate hepatitis C as a global health threat, as set out by the World Health Organization, an integrated approach based on the optimization of care delivery and increased access to harm reduction and treatment for PWID is needed. Thanks to the development of safe and effective antiviral agents, eradication of the infection is now possible in almost all treated patients, leading to a significant reduction but not the elimination of the risk for HCC in cured patients. This is particularly relevant among aged populations who have cofactors of morbidity known to accelerate HCC progression, such as diabetes, obesity, and excessive alcohol consumption. Given the restless accumulation of individuals with cured HCV infection, the implementation of risk-stratified surveillance programs becomes impellent from a cost-effectiveness perspective, whereas the availability of a performant biomarker to predict HCC in cured patients remains an unmet clinical need.

RESUMEN

BACKGROUND: Infiltrated margins of resection (R1) and lymph node invasion are dominant negative predictors of survival in patients with a resectable perihilar cholangiocarcinoma. Less clear is whether survival predictors stratify differently between R0 (tumor-free margins) and R1 patients and whether the prognosis of the latter patients is influenced by the pattern of neoplastic infiltration (ie, radial versus longitudinal infiltration). We retrospectively evaluated a series of reported resected perihilar cholangiocarcinoma to obtain insights on the predictive power of these histologic features. METHODS: The study includes 264 patients with perihilar cholangiocarcinoma treated between 2004 and 2019 in our center and followed up for >18 months. There were 176 patients with R0 (66.6%) and 88 patients with R1 (33.3%), 31 with radial infiltration only, 30 with longitudinal infiltration only, and 27 with both infiltration patterns. In all patients, the criteria for resection was the absence of metastatic involvement (ie, distant organ metastases, liver metastases, and lymph node metastases beyond the hepatoduodenal ligament). Histopathologic specimens of the resected tumors were centrally reviewed by a pathologist unaware of the clinical outcomes. RESULTS: Three- and 5-year long-term survival were significantly better in R0 (respectively) compared to R1 patients (55% and 42% vs 42% and 18%, respectively, P < .05). In R1 patients with radial infiltration only and those with radial + longitudinal infiltration, both disease-free and overall survival were worse than those with longitudinal infiltration only (median disease-free survival of 18 and 23 months, respectively, P < .05, median overall survival of 33 and 39 months, respectively, P < .05). At multivariable analysis, nodal status, side of hepatectomy, grading, and presence of radial margin infiltration were associated with long-term outcome. CONCLUSION: Radial infiltration of resection margins enhances the negative prognostic value of R1 margins in perihilar cholangiocarcinoma patients and should specifically be accounted for in the prediction of the outcome of adjuvant therapy.

RESUMEN

BACKGROUND AND AIMS: Metabolic dysfunction (MD)-associated fatty liver disease has been proposed to identify individuals at risk of liver events irrespectively of the contemporary presence of other liver diseases. The aim of this study was to examine the impact of MD in patients cured of chronic hepatis C (CHC). PATIENTS AND METHODS: We analysed data from a real-life cohort of 2611 Italian patients cured of CHC with direct antiviral agents and advanced liver fibrosis, without HBV/HIV, transplantation and negative for hepatocellular carcinoma (HCC) history (age 61.4 ± 11.8 years, 63.9% males, median follow-up 34, 24-40 months). Information about ultrasonographic steatosis (US) after sustained virological response was available in 1978. RESULTS: MD affected 58% of patients, diagnosed due to the presence of diabetes (MD-diabetes, 19%), overweight without diabetes (MD-overweight, 37%) or multiple metabolic abnormalities without overweight and diabetes (MD-metabolic, 2%). MD was more frequent than and not coincident with US (32% MD-only, 23% MD-US and 13% US-only). MD was associated with higher liver stiffness (p < 0.05), particularly in patients with MD-diabetes and MD-only subgroups, comprising older individuals with more advanced metabolic and liver disease (p < 0.05). At Cox proportional hazard multivariable analysis, MD was associated with increased risk of HCC (HR 1.97, 95% CI 1.27-3.04; p = 0.0023). Further classification according to diagnostic criteria improved risk stratification (p < 0.0001), with the highest risk observed in patients with MD-diabetes. Patients with MD-only appeared at highest risk since the sustained virological response achievement (p = 0.008), with a later catch-up of those with combined MD-US, whereas US-only was not associated with HCC. CONCLUSIONS: MD is more prevalent than US in patients cured of CHC with advanced fibrosis and identifies more accurately individuals at risk of developing HCC.

RESUMEN

Since the initial development of the exposome concept, much effort has been devoted to the characterisation of the exposome through analytical, epidemiological, and toxicological/mechanistic studies. There is now an urgent need to link the exposome to human diseases and to include exposomics in the characterisation of environment-linked pathologies together with genomics and other omics. Liver diseases are particularly well suited for such studies since major functions of the liver include the detection, detoxification, and elimination of xenobiotics, as well as inflammatory responses. It is well known that several liver diseases are associated with i) addictive behaviours such as alcohol consumption, smoking, and to a certain extent dietary imbalance and obesity, ii) viral and parasitic infections, and iii) exposure to toxins and occupational chemicals. Recent studies indicate that environmental exposures are also significantly associated with liver diseases, and these include air pollution (particulate matter and volatile chemicals), contaminants such as polyaromatic hydrocarbons, bisphenol A and per-and poly-fluorinated substances, and physical stressors such as radiation. Furthermore, microbial metabolites and the "gut-liver" axis play a major role in liver diseases. Exposomics is poised to play a major role in the field of liver pathology. Methodological advances such as the exposomics-metabolomics framework, the determination of risk factors' genomic and epigenomic signatures, and cross-species biological pathway analysis should further delineate the impact of the exposome on the liver, opening the way for improved prevention, as well as the identification of new biomarkers of exposure and effects, and additional therapeutic targets.

RESUMEN

Background & Aims: Non-invasive tests (NITs) offer a practical solution for advanced fibrosis identification in non-alcoholic fatty liver disease (NAFLD). Despite increasing implementation, their use is not standardised, which can lead to inconsistent interpretation and risk stratification. We aimed to assess the types of NITs and the corresponding cut-offs used in a range of healthcare settings. Methods: A survey was distributed to a convenience sample of liver health experts who participated in a global NAFLD consensus statement. Respondents provided information on the NITs used in their clinic with the corresponding cut-offs and those used in established care pathways in their areas. Results: There were 35 respondents from 24 countries, 89% of whom practised in tertiary level settings. A total of 14 different NITs were used, and each respondent reported using at least one (median = 3). Of the respondents, 80% reported using FIB-4 and liver stiffness by vibration-controlled transient elastography (Fibroscan®), followed by the NAFLD fibrosis score (49%). For FIB-4, 71% of respondents used a low cut-off of <1.3 (range <1.0 to <1.45) and 21% reported using age-specific cut-offs. For Fibroscan®, 21% of respondents used a single liver stiffness cut-off: 8 kPa in 50%, while the rest used 7.2 kPa, 7.8 kPa and 8.7 kPa. Among the 63% of respondents who used lower and upper liver stiffness cut-offs, there were variations in both values (<5 to <10 kPa and >7.5 to >20 kPa, respectively). Conclusions: The cut-offs used for the same NITs for NAFLD risk stratification vary between clinicians. As cut-offs impact test performance, these findings underscore the heterogeneity in risk-assessment and support the importance of establishing consistent guidelines on the standardised use of NITs in NAFLD management. Lay summary: Owing to the high prevalence of non-alcoholic fatty liver disease (NAFLD) in the general population it is important to identify those who have more advanced stages of liver fibrosis, so that they can be properly treated. Non-invasive tests (NITs) provide a practical way to assess fibrosis risk in patients. However, we found that the cut-offs used for the same NITs vary between clinicians. As cut-offs impact test performance, these findings highlight the importance of establishing consistent guidelines on the standardised use of NITs to optimise clinical management of NAFLD.

RESUMEN

In 2016, the Hepatitis B and C Public Policy Association (HepBCPPA), gathered all the main stakeholders in the field of hepatitis C virus (HCV) to launch the now landmark HCV Elimination Manifesto, calling for the elimination of HCV in the EU by 2030. Since then, many European countries have made progress towards HCV elimination. Multiple programmes-from the municipality level to the EU level-were launched, resulting in an overall decrease in viremic HCV infections and liver-related mortality. However, as of 2021, most countries are not on track to reach the 2030 HCV elimination targets set by the WHO. Moreover, the COVID-19 pandemic has resulted in a decrease in HCV diagnoses and fewer direct-acting antiviral treatment initiations in 2020. Diagnostic and therapeutic tools to easily diagnose and treat chronic HCV infection are now well established. Treating all patients with chronic HCV infection is more cost-saving than treating and caring for patients with liver-related complications, decompensated cirrhosis or hepatocellular carcinoma. It is more important than ever to reinforce and scale-up action towards HCV elimination. Yet, efforts urgently need the dedicated commitment of policymakers at all governmental and policy levels. Therefore, the third EU Policy Summit, held in March 2021, featured EU parliamentarians and other key decision makers to promote dialogue and take strides towards securing wider EU commitment to advance and achieve HCV elimination by 2030. We have summarized the key action points and reported the 'Call-to-Action' statement supported by all the major relevant European associations in the field.

RESUMEN

Hepatocellular carcinoma (HCC) is a common complication in patients with chronic liver disease and leads to significant morbidity and mortality. Liver disease and liver cancer are preventable by mitigating and managing common risk factors, including chronic hepatitis B and C infection, alcohol use, diabetes, obesity and other components of the metabolic syndrome. The management of patients with HCC requires treatment of the malignancy and adequate control of the underlying liver disease, as preserving liver function is critical for successful cancer treatment and may have a relevant prognostic role independent of HCC management. Hepatologists are the ideal providers to guide the care of patients with HCC as they are trained to identify patients at risk, apply appropriate surveillance strategies, assess and improve residual liver function, evaluate candidacy for transplant, provide longitudinal care to optimize and preserve liver function during and after HCC treatment, survey for cancer recurrence and manage its risk factors, and prevent and treat decompensating events. We highlight the need for a team-based holistic approach to the patient with liver disease and HCC and identify necessary gaps in current care and knowledge.

RESUMEN

Background: Endotoxemia causes endothelial dysfunction and microthrombosis, which are pathogenic mechanisms of coagulopathy and organ failure during sepsis. Simvastatin has potential anti-thrombotic effects on liver endothelial cells. We investigated the hemostatic changes induced by lipopolysaccharide (LPS) and explored the protective effects of simvastatin against liver vascular microthrombosis. Methods and results: We compared male Wistar rats exposed to LPS (5 mg/kg one i.p. dose) or saline in two experimental protocols­placebo (vehicle) and simvastatin (25 mg/kg die, orally, for 3 days before LPS). Morphological studies were performed by light- and electron-microscopy analyses to show intravascular fibrin deposition, vascular endothelial structure and liver damage. Peripheral- and organ-hemostatic profiles were analyzed using whole blood viscoelastometry by ROTEM, liver biopsy and western-blot/immunohistochemistry of thrombomodulin (TM), as well as immunohistochemistry of the von Willebrand factor (VWF). LPS-induced fibrin deposition and liver vascular microthrombosis were combined with a loss of sinusoidal endothelial TM expression and VWF-release. These changes were associated with parenchymal eosinophilia and necrosis. ROTEM analyses displayed hypo-coagulability in the peripheral blood that correlated with the degree of intrahepatic fibrin deposition (p < 0.05). Simvastatin prevented LPS-induced fibrin deposition by preserving TM expression in sinusoidal cells and completely reverted the peripheral hypo-coagulability caused by endotoxemia. These changes were associated with a significant reduction of liver cell necrosis without any effect on eosinophilia. Conclusions: Simvastatin preserves the antithrombotic properties of sinusoidal endothelial cells disrupted by LPS, deserving pharmacological properties to contrast sepsis-associated coagulopathy and hepatic failure elicited by endotoxemia

RESUMEN

BACKGROUND: Sofosbuvir, a prodrug nucleoside inhibitor of hepatitis C virus, has a predominant circulating metabolite that is renally eliminated. Whether sofosbuvir is associated with chronic kidney disease (CKD) progression is not well understood. METHODS: We performed a retrospective analysis of patients with estimated glomerular filtration rate (eGFR) 30-89 mL/min/1.73 m2 treated with sofosbuvir in 76 Phase 2/3 registrational trials. We evaluated eGFR at each study visit. Separately, we performed a retrospective analysis of an administrative claims database (IQVIA PharMetrics Plus™) to compare the risk of incident end-stage renal disease (ESRD) associated with the use of sofosbuvir or non-sofosbuvir regimens among patients with CKD using propensity score methods. Exposure, CKD status and outcomes were determined using diagnosis and medication claim codes. Cox proportional hazards methods were used to estimate ESRD risk. RESULTS: Among 4642 trial participants with baseline stage 2 CKD (eGFR 60-89 ml/min/1.73 m2 ) and 682 trial participants with stage 3 CKD (eGFR 30-59 ml/min/1.73 m2 ) mean (SD) eGFR improved from baseline to 4 weeks post-treatment (+0.7 [9.3] and +2.6 [8.8] ml/min/1.73 m2 , respectively; p < 0.001 each). In the second analysis, among 2042 patients with CKD receiving sofosbuvir-based regimens compared to 431 receiving non-sofosbuvir-based regimens, after adjusting for baseline covariates and weighting based on treatment propensity scores, there was no significant difference in risk of ESRD (adjusted HR = 0.85, 95% CI: 0.51-1.42). CONCLUSIONS: Clinical trial participants with CKD did not experience worsening eGFR during sofosbuvir-based treatment, and sofosbuvir was not associated with an increased risk of ESRD in patients with CKD in a nationally-representative administrative claims database.

RESUMEN

Microelimination targets specific subpopulations and/or geographic settings for hepatitis C virus (HCV) elimination. This review reports on global HCV microelimination literature published from 2013 to 2020. Data were extracted from publications to report a score based on the four key components defining microelimination. Sustained virologic response (SVR) and treatment initiation proportions were calculated for each manuscript and grouped means of these estimates were compared depending on microelimination score and care setting. A total of 83% of the studies were from high-income settings and mainly included people who use drugs or those incarcerated. Among manuscripts, 18 had "low" microelimination scores, 11 had "high" scores, and the differences in mean proportion who initiated treatment and achieved SVR between low and high score groups were statistically significant. Microelimination can be a useful complementary strategy for driving engagement in HCV treatment and cure. Our analysis suggests that adhering to more of the core microelimination components can improve outcomes. This study is registered with Prospero, registration identification: CRD42020175211.

RESUMEN

BACKGROUND AND AIM: The World Health Organization (WHO) goal of hepatitis C virus (HCV) elimination by 2030 relies on the scaling-up of both identification and linkage to care of the infected population, worldwide. In Italy, the estimated burden of HCV carriers who are unaware of their infection amounts to 200 000 persons, a projection that reinforces the need for broadening population access to effective screening programmes. METHODS: A pivotal screening programme targeting subjects born between 1969 and 1989 has been conducted in Lombardy, Northern Italy, where point-of-care (POC) testing was offered for free concomitantly to COVID-19 vaccination. RESULTS: Amongst 7219 subjects born between 1969 and 1989 who underwent HCV screening through POC, 7 (0.10%) subjects tested anti-HCV positive: 5 (0.07%) had confirmed anti-HCV positivity (Table 1) and 4 of them (0.05%) were HCV-RNA positive by standard confirmation tests. CONCLUSIONS: This pivotal study demonstrated the feasibility of a POC-based anti-HCV screening programme in young adults undergoing COVID-19 vaccination. The prevalence of HCV infection in subjects born in the 1969-1989 cohort in Italy seems to be lower than previously estimated. Whether the extension of this programme to subjects born before 1969 could lead to improved screening effectiveness should be a matter of debate.

RESUMEN

Hepatocellular carcinoma (HCC) is on the rise globally, causing more than 800 thousand deaths annually, with an estimated annual percent change of 0.51 for causes other than viral hepatitis, including nonalcoholic fatty liver disease (NAFLD). The incidence of NAFLD-related HCC is peaking in several Far East regions (6-12% vs. 2-3% in Western Europe and USA), HCC risk being mainly driven by the epidemic of obesity and diabetes, both favored by an unhealthy diet and sedentary lifestyle. Under inherited susceptibility outlined by such genetic markers as variants in PNPLA3, TM6SF2 and MBOAT7, neoplastic transformation of NAFLD is driven by sublethal lipotoxicity consequent to hepatocyte lipid overload, whereas a myriad of factors spanning from subverted circadian homeostasis and gut dysbiosis to alcohol abuse and tobacco may interact as risk modifiers. At variance with viral HCC, NAFLD-HCC shows a frequent association with cardiovascular co-morbidities, absence of cirrhosis in up to half of patients and an association with persistently normal transaminase values. All these misleading features of NAFLD-related HCC account for the low uptake of surveillance and linkage to curative treatments that has been reported in patients with this cancer, a downside that could be attenuated when scores for cost-effective risk stratification become available.

RESUMEN

BACKGROUND & AIMS: Achieving sustained virologic response (SVR) among patients with hepatitis C virus (HCV) leads to patient reported outcome (PRO) improvement. We aimed to assess the long-term post-SVR PRO trends in HCV patients with cirrhosis. METHODS: Patients with HCV and cirrhosis treated in clinical trials with direct acting antiviral agents (DAAs) who achieved SVR-12 were prospectively enrolled in a long-term registry (clinicaltrials.gov #NCT02292706). PROs were collected every 24 weeks using the Short Form-36v2 (SF-36), CLDQ-HCV, and WPAI-HCV. RESULTS: Pre-treatment baseline data were available for 854 cirrhotic patients who achieved SVR after DAAs. Of these, 730 had compensated (CC) and 124 had decompensated cirrhosis (DCC) before treatment- patients with DCC reported severe impairment in their PROs in comparison to CC patients (by mean -5% to -16% of a PRO range size; p < .05 for 16 out of 20 studied PROs]. After achieving SVR and registry enrollment, significant PRO improvements were noted from pre-treatment levels in 11/20 domains for those with DCC (+4% to +21%) and 19/20 PRO domains in patients with CC (+3% to +17%). Patients with baseline DCC had higher rates of hepatocellular carcinoma and mortality (P < .05). In patients with CC, the PRO gains persisted up to 168 weeks (3.5 years) of registry follow-up. In patients with DCC, the improvements lasted for at least 96 weeks but a declining trend after year 2. CONCLUSIONS: Patients with HCV cirrhosis experience severe PRO impairment at baseline with sustainable improvement after SVR. Though those with DCC experience improvement, there is a decline after 2 years.

RESUMEN

The aim of this study was to examine the impact of features of dysmetabolism on liver disease severity, evolution, and clinical outcomes in a real-life cohort of patients treated with direct acting antivirals for chronic hepatitis C virus (HCV) infection. To this end, we considered 7,007 patients treated between 2014 and 2018, 65.3% with advanced fibrosis, of whom 97.7% achieved viral eradication (NAVIGATORE-Lombardia registry). In a subset (n = 748), liver stiffness measurement (LSM) was available at baseline and follow-up. Higher body mass index (BMI; odds ratio [OR] 1.06 per kg/m2 , 1.03-1.09) and diabetes (OR 2.01 [1.65-2.46]) were independently associated with advanced fibrosis at baseline, whereas statin use was protective (OR 0.46 [0.35-0.60]; P < 0.0001 for all). The impact of BMI was greater in those without diabetes (P = 0.003). Diabetes was independently associated with less pronounced LSM improvement after viral eradication (P = 0.001) and in patients with advanced fibrosis was an independent predictor of the most frequent clinical events, namely de novo hepatocellular carcinoma (HCC; hazard ratio [HR] 2.09 [1.20-3.63]; P = 0.009) and cardiovascular events (HR 2.73 [1.16-6.43]; P = 0.021). Metformin showed a protective association against HCC (HR 0.32 [0.11-0.96]; P = 0.043), which was confirmed after adjustment for propensity score (P = 0.038). Diabetes diagnosis further refined HCC prediction in patients with compensated advanced chronic liver disease at high baseline risk (P = 0.024). Conclusion: Metabolic comorbidities were associated with advanced liver fibrosis at baseline, whereas statins were protective. In patients with advanced fibrosis, diabetes increased the risk of de novo HCC and of cardiovascular events. Optimization of metabolic comorbidities treatment by a multi-disciplinary management approach may improve cardiovascular and possibly liver-related outcomes.

RESUMEN

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent, yet largely underappreciated liver condition which is closely associated with obesity and metabolic disease. Despite affecting an estimated 1 in 4 adults globally, NAFLD is largely absent on national and global health agendas. METHODS: We collected data from 102 countries, accounting for 86% of the world population, on NAFLD policies, guidelines, civil society engagement, clinical management, and epidemiologic data. A preparedness index was developed by coding questions into 6 domains (policies, guidelines, civil awareness, epidemiology and data, NAFLD detection, and NAFLD care management) and categorising the responses as high, medium, and low; a multiple correspondence analysis was then applied. RESULTS: The highest scoring countries were India (42.7) and the United Kingdom (40.0), with 32 countries (31%) scoring zero out of 100. For 5 of the domains a minority of countries were categorised as high-level while the majority were categorised as low-level. No country had a national or sub-national strategy for NAFLD and <2% of the different strategies for related conditions included any mention of NAFLD. National NAFLD clinical guidelines were present in only 32 countries. CONCLUSIONS: Although NAFLD is a pressing public health problem, no country was found to be well prepared to address it. There is a pressing need for strategies to address NAFLD at national and global levels. LAY SUMMARY: Around a third of the countries scored a zero on the NAFLD policy preparedness index, with no country scoring over 50/100. Although NAFLD is a pressing public health problem, a comprehensive public health response is lacking in all 102 countries. Policies and strategies to address NAFLD at the national and global levels are urgently needed.

RESUMEN

BACKGROUND: Migrants represent a key target population for viral hepatitis micro-elimination programs and are important targets for specific prevention, screening and treatment programs. AIMS: To raise awareness on viral hepatitis among migrants and key stakeholders, assess the prevalence of HBV and HCV among migrants, and determine an optimal and scalable viral hepatitis screening and treatment protocol. MATERIAL AND METHODS: Unselected, consecutive migrants reaching the costs of Italy were screened for HBV, HCV, HDV and HIV markers. Anagraphic and anamnestic information were used to identify viral hepatitis endemic hotspots in the countries of birth or transit. Personal data, including migration route, test results and treatment, were collected and stored in a dedicated database RESULTS: 362 patients were recruited in 2019; median age was 28 years, 71% were male. Most of the patients were African (54%) or Asian (40%). 49% positive for at least one HBV marker: 2.2% HBsAg (asymptomatic carriers with low viremia); 10.6% anti-HBs; 28.5% anti-HBs and anti-HBc, 1.7% anti-HCV, 0.6% anti-HIV, with low or undetectable viral load. Libya was the nexus shared by most of the positive, reactive cases. HCV and HIV markers were only found in migrants already resident in Italy for more than 6-12 months. CONCLUSION: Low to moderate prevalence of hepatitis B markers were observed in African and Asian first arrival migrants. Migrants positive for HCV and HIV likely acquired the infection after arrival in Italy, suggesting migrants are at risk of contracting viral infections once in Italy, highlighting the importance of ensuring access to prevention for migrant communities.
