    Quality of Life in Patients with Hepatic Encephalopathy Treated with Rifaximin: A Systematic Review

    by Rodolfo Sacco, Ambra Corti, Luca Giacomelli, Antonio Facciorusso

    Background & Aims: Hepatic encephalopathy (HE) significantly impairs quality of life (QoL) in patients with cirrhosis. While rifaximin is established in HE treatment and prevention, its specific impact on QoL remains less clearly defined. This systematic review aims to evaluate the effects of rifaximin on QoL in patients with HE. Methods: A comprehensive literature search was conducted in MEDLINE/PubMed, Embase, and CENTRAL through November 2025. Clinical studies evaluating rifaximin's impact on QoL in patients with decompensated cirrhosis and HE were included. Study selection followed PRISMA guidelines. Data extraction focused on study design, population, treatment, and QoL outcomes. Results: Out of 4,343 records screened, 10 studies met the inclusion criteria. Most studies evaluated rifaximin in comparison with placebo and focused on patients with minimal or covert HE. Rifaximin was almost consistently associated with statistically significant improvements in overall and domain-specific QoL scores compared with placebo, particularly in fatigue, activity and emotional function. These benefits were observed across different dosages and treatment durations. In comparative studies, rifaximin showed QoL outcomes comparable to those of lactulose, L-ornithine L-aspartate, and combination regimens. One study reported greater improvement in QoL with nitazoxanide, although rifaximin showed significant improvements in specific QoL domains. Conclusion: Rifaximin is associated with improvements in QoL in patients with cirrhosis and HE, with benefits observed across multiple domains and outcomes comparable to alternative therapies. Further high-quality comparative trials, particularly in patients with overt HE and in prophylactic settings, are needed to confirm these findings and to better inform patient-centered management strategies.

    Applying the COM ‐B Model to Identify Barriers to Bulevirtide Adherence in Chronic Hepatitis D: A Multicenter Italian Study

    by Lorenzo Badia, Alessia Ciancio, Marco Distefano, Antonio Izzi, Alessandro Loglio

    Adherence to treatment is a key determinant of clinical outcomes in chronic infectious diseases, including hepatitis D virus (HDV) infection. Even if bulevirtide (BLV) has shown a promising adherence profile in clinical trials, adherence is often compromised by various barriers in the context of HDV—especially among migrant populations. The aim of this study was to investigate the factors influencing adherence to BLV treatment in real‐life settings in Italy. From May to September 2024, two anonymous surveys—one for HDV patients undergoing bulevirtide (BLV) treatment and one for their hepatologists—were conducted across five tertiary centers in Italy. The study employed the COM‐B model (Capability, Opportunity, Motivation–Behaviour) to systematically explore the behavioural drivers influencing treatment adherence in this population and unmet needs. Of the 86 consecutive adult patients receiving bulevirtide (BLV) who were invited to participate, 83 (97%) completed the multilingual survey (35% > 60 years old, 48% Italians; 80% under BLV > 6 months) and were included in the analysis, together with 13 hepatologists. The findings revealed key challenges related to patient education, logistical access to medication, and psychological factors affecting motivation. Specifically, 10% had considered discontinuing treatment and 10% admitted to having missed doses. A deeper understanding of these multifactorial determinants may aid in the development of targeted interventions to enhance adherence and achieve personalized therapeutic outcomes for individuals living with HDV.

    The Medical Impact of Hepatitis D Virus Infection in Natives and Immigrants: The Italian Paradigm

    by Gian Paolo Caviglia, Eleonora Dileo, Antonella Olivero, Giulio Mengozzi, Alessia Ciancio, Alessandro Loglio, Mauro Viganò, Stefano Fagiuoli, Piero Colombatto, Barbara Coco, et al.

    Background and Aim: Ongoing migratory flows are reconstituting the hepatitis D virus (HDV) reservoir in Italy. We aimed to characterise the current clinical and virologic features of HDV infection in both native Italians and migrants. Methods: We enrolled 515 hepatitis B surface antigen (HBsAg)‐positive patients with detectable anti‐HDV antibodies from 32 Italian centres between August 2022 and July 2024; all patients underwent centralised virologic assessment. Results: Overall, 432 out of 515 (83.9%) patients were HDV‐RNA‐positive (4.39, 1.30–5.82 Log IU/mL; 99.0% HDV genotype‐1). HDV‐RNA levels correlated with ALT ( r s = 0575, 0.514–0.630) and hepatitis B core‐related antigen ( r s = 0.521, 0.455–0.581). Native Italians ( n = 317; 61.6%) were older than migrants ( n = 198; 38.4%) (median age: 60, 55–65 vs. 46, 39–54 years; p < 0.001) and were more frequently male (68.1% vs. 49.5%; p < 0.001), with a higher prevalence of liver cirrhosis (70.3% vs. 50.5%; p < 0.001) and hepatocellular carcinoma (14.8% vs. 0.5%; p < 0.001). Among Italians, 223 (70.3%) had liver cirrhosis, 46 (14.5%) had chronic hepatitis D (CHD) without cirrhosis and 48 (15.1%) exhibited inactive/minimal disease with low viremia (≤ 3 Log IU/mL). Among migrants, 100 (50.5%) had liver cirrhosis, 58 (29.3%) had CHD and 40 (20.2%) showed inactive/minimal disease with low viremia (≤ 3 Log IU/mL). Conclusions: The current clinical landscape of chronic HDV infections in Italy is heterogeneous, changing the perspective of CHD as uniformly severe; although cirrhosis remains common, a substantial proportion of both native Italians and migrants present with milder forms of disease.

    Lenvatinib Is Highly Effective in Patients with Hepatocellular Carcinoma Related to Both Metabolic Dysfunction-Associated Steatohepatitis and Alcoholic Etiology: A Propensity Score Analysis

    by Rodolfo Sacco, Edoardo G. Giannini, Raffaella Tortora, Giovan Giuseppe Di Costanzo, Andrea Mega, Luca Marzi, Giulia Pieri, Andrea Pasta, Bruno Daniele, Piera Federico, et al.

    Background and aims: Metabolic dysfunction-associated steatotic liver disease (MASLD)-related hepatocellular carcinoma (HCC) may have distinct biological characteristics influencing systemic treatment response. However, the prognostic impact of MASLD vs. alcohol-related HCC in patients receiving lenvatinib remains unclear. This study aimed to assess lenvatinib’s effectiveness and safety in these populations. Methods: A multicenter cohort of 378 HCC patients treated with lenvatinib (2019–2024) was analyzed. Propensity score matching was performed based on age, sex, tumoral stage, alpha-fetoprotein levels and Child–Pugh class. Survival was estimated using Kaplan–Meier analysis and compared with the log-rank test. Results were expressed as HR and 95% CI. Results: After matching, 115 patients per group were compared. Median OS was 21 months (95% CI: 20–23) in the group with metabolic dysfunction-associated steatohepatitis (MASH) and 19 months (95% CI: 18–21) in the group with alcohol etiology (p = 0.18). In multivariate analysis, only Child–Pugh class (HR 2.67, 95% CI: 1.84–5.41) and tumor stage (HR 2.18, 95% CI: 1.57–6.93) resulted as significant predictors of OS. Median PFS was 9 months (95% CI: 8–9) in patients with MASH and 9 months (95% CI: 7–10) in patients with alcohol etiology (p = 0.33). Only the Child–Pugh class was a significant predictor of PFS in univariate analysis (HR 1.56, 95% CI: 1.15–3.41; p = 0.03). No difference in terms of adverse event rate was observed between the two groups. Conclusions: Lenvatinib is effective in patients with both MASH- and alcohol-related HCC, with no difference in oncological outcomes between the two groups.

    Assessment of Response and Safety of Bulevirtide Treatment in Patients with Chronic Delta Virus Infection: The ARISTOTLE Pilot Observational Study

    by Luca Rinaldi, Mauro Viganò, Alessia Ciancio, Alfredo Caturano, Vincenzo Messina, Grazia Anna Niro, Nicolina Capoluongo, Alessandro Loglio, Letizia Marinaro, Aldo Marrone, et al.

    Introduction: Hepatitis D virus (HDV) infection remains a significant global health challenge due to its severity and high risk of progression to cirrhosis and hepatocellular carcinoma (HCC). Bulevirtide, a novel HDV entry inhibitor, has shown promise in managing chronic hepatitis D by blocking viral entry into hepatocytes. This study evaluated the efficacy and safety of bulevirtide in reducing HDV RNA levels and improving liver function in a real-life cohort of Italian patients with HDV infection. Methods: This multicenter prospective trial enrolled 108 consecutive patients with chronic HDV infection, from June 2023 to June 2024, who received 2 mg/day of bulevirtide in combination with a nucleoside/nucleotide analogue for hepatitis B virus (HBV) infection. Patients with any stage of liver fibrosis or compensated cirrhosis were included. Data collected included demographic and clinical characteristics, liver function tests, HDV RNA levels, and adverse events at baseline and 6 months. Results: The virological response was achieved in 54.6% of patients (n = 59), with 36 demonstrating undetectable HDV RNA levels. Among responders, ALT levels decreased significantly from 67.0 U/mL [IQR 44.0–116.3] to 31.5 U/mL [IQR 24.0–36.5, p = 0.001], and AST levels from 66.0 U/mL [IQR 46.5–91.0] to 32.5 U/mL [IQR 28.0–38.0, p = 0.021]. Median HDV RNA dropped from 29,800 IU/mL [IQR 3100–375,000] to 0 IU/mL [IQR 0–291, p < 0.001]. No significant predictors of response emerged. Mild adverse events, including pruritus (5.6%) and injection-site reactions (1.9%) and flu-like syndrome (0.9) were reported, with no treatment discontinuation. Conclusions: Bulevirtide effectively reduces HDV RNA levels and improves liver function with a favorable safety profile, offering a promising therapeutic option for chronic hepatitis D. Further large-scale studies are needed to confirm these findings and explore long-term outcomes.

    Safety of Sofosbuvir-Based Direct-Acting Antivirals for Hepatitis C Virus Infection and Direct Oral Anticoagulant Co-Administration

    by Valerio Rosato, Riccardo Nevola, Marcello Dallio, Pierpaolo Di Micco, Angiola Spinetti, Laert Zeneli, Alessia Ciancio, Michele Milella, Piero Colombatto, Giuseppe D’adamo, et al.

    Background: Direct oral anticoagulants (DOACs) are recommended for the management of thrombosis prophylaxis, especially in patients with atrial fibrillation. As substrates of cytochrome P450 (CYP) 3A4 and/or P-glycoprotein, they are implicated in potential drug–drug interactions. NS5A/NS5B inhibitors are direct-acting agents (DAAs) against the Hepatitis C Virus (HCV) infection that exert a mild inhibition of P-glycoprotein without effects on CYP3A4. A DOAC and NS5A/NS5B inhibitor co-administration may lead to an increased risk of bleeding. Real-world data on the concomitant use of DOACs and DAAs are scarce. On this purpose, we perform a retrospective analysis on the risk of vascular adverse events (bleeding and thrombosis) among HCV patients under DOAC/DAA therapy, even in advanced liver disease. Methods: Between May 2015 and April 2023, patients treated with sofosbuvir-based DAA regimens and DOACs were consecutively included in this study from 12 Italian medical centers. Baseline characteristics, especially concerning bleeding risk and liver function, were collected. The occurrence of bleeding events, classified as major and minor, was the primary endpoint. Secondary endpoints were the rate of any thrombotic events and/or the need for discontinuation of one or both treatments. Moreover, a cohort of patients, matched by demographic characteristics (age and sex), that switched to vitamin K antagonists (VKAs) during the antiviral treatment was compared with the DOAC/DAA group. Results: A total of 104 patients were included. Thirty-eight of them (36.5%) were cirrhotic. Atrial fibrillation was an indication for anticoagulation in almost all cases (76%). Rivaroxaban (35.6%) was the most used DOAC, followed by apixaban (26.9%), dabigatran (19.2%) and edoxaban (18.3%). Sofosbuvir/velpatasvir (78.8%) was the most prescribed DAA, and all patients were already on anticoagulant therapy before the start of DAAs. During concomitant DOAC/DAA treatment, no major bleeding events were recorded, while four minor bleeding events occurred, but none resulted in DAA or DOAC discontinuation. At univariate analysis, the only additional risk factor statistically related to bleeding events was the anticoagulant therapy (hazard ratio [HR]: 13.2, 95% confidence interval 1,6-109). Performing an evaluation by a LOGIT binomial analysis with demographic characteristics, the antiplatelet therapy remained statistically associated to bleeding events. No significant differences were found in the rate of clinically relevant bleeding when the main population was compared with the VKA-switched cohort. A single major bleeding event leading to anticoagulation and DAA discontinuation was reported in VKA-switched matched cohort. Conclusions: In our study, the concomitant use of NS5A/NS5B inhibitors with DOAC showed good safety, and the only risk factor associated with bleeding events was the concomitant antiplatelet therapy. These findings support the use of DOACs during sofosbuvir-based HCV treatment, even in advanced liver disease. Replacing DOACs with VKAs does not appear to be of clinical benefit.

    Final Results from the First European Real-World Experience on Lusutrombopag Treatment in Cirrhotic Patients with Severe Thrombocytopenia: Insights from the REAl-World Lusutrombopag Treatment in ITalY Study

    by Paolo Gallo, Antonio De Vincentis, Francesca Terracciani, Andrea Falcomatà, Valeria Pace Palitti, Maurizio Russello, Anthony Vignone, Domenico Alvaro, Raffaella Tortora, Marco Biolato, et al.

    Background and aims: Management of severe thrombocytopenia poses significant challenges in patients with chronic liver disease. Here, we aimed to evaluate the first real-world European post-marketing cohort of cirrhotic patients treated with lusutrombopag, a thrombopoietin receptor agonist, verifying the efficacy and safety of the drug. Methods: In the REAl-world Lusutrombopag treatment in ITalY (REALITY) study, we collected data from consecutive cirrhotic patients treated with lusutrombopag in 19 Italian hepatology centers, mostly joined to the “Club Epatologi Ospedalieri” (CLEO). Primary and secondary efficacy endpoints were the ability of lusutrombopag to avoid platelet transfusions and to raise the platelet count to ≥50,000/μL, respectively. Treatment-associated adverse events were also collected. Results: A total of 66 patients and 73 cycles of treatment were included in the study, since 5 patients received multiple doses of lusutrombopag over time for different invasive procedures. Fourteen patients (19%) had a history of portal vein thrombosis (PVT). Lusutrombopag determined a significant increase in platelet count [from 37,000 (33,000–44,000/μL) to 58,000 (49,000–82,000), p < 0.001]. The primary endpoint was met in 84% of patients and the secondary endpoint in 74% of patients. Baseline platelet count was the only independent factor associated with response in multivariate logistic regression analysis (OR for any 1000 uL of 1.13, CI95% 1.04–1.26, p 0.01), with a good discrimination power (AUROC: 0.78). Notably, a baseline platelet count ≤ 29,000/μL was identified as the threshold for identifying patients unlikely to respond to the drug (sensitivity of 91%). Finally, de novo PVT was observed in four patients (5%), none of whom had undergone repeated treatment, and no other safety or hemorrhagic events were recorded in the entire population analyzed. Conclusions: In this first European real-world series, lusutrombopag demonstrated efficacy and safety consistent with the results of registrational studies. According to our results, patients with baseline platelet counts ≤29,000/μL are unlikely to respond to the drug.

    Epidemiology of HCV and HBV in a High Endemic Area of Southern Italy: Opportunities from the COVID-19 Pandemic—Standardized National Screening or One Tailored to Local Epidemiology?

    by Riccardo Nevola, Vincenzo Messina, Aldo Marrone, Nicola Coppola, Carolina Rescigno, Vincenzo Esposito, Vincenzo Sangiovanni, Ernesto Claar, Mariantonietta Pisaturo, Francesco Maria Fusco, et al.

    The COVID-19 pandemic led to the hospitalization of an unselected population with the possibility to evaluate the epidemiology of viral hepatitis. Thus, a retrospective multicenter study was conducted in an area of Southern Italy with the aim of assessing the prevalence of HCV and HBV markers and the ability of current screening program to capture cases. We evaluated 2126 hospitalized patients in seven COVID Centers of Naples and Caserta area in which 70% of the Campania population lives. HBsAg and HCV-Ab prevalence was 1.6% and 5.1%, respectively, with no differences between gender. Decade distribution for birth year shows a bimodal trend of HCV prevalence, with a peak (11.6%) in the decade 1930–1939 and a second peak (5.6%) for those born in 1960–1969. An analysis of the screening period imposed by the Italian government for those born between 1969 and 1989 shows that only 17% of cases of HCV infection could be captured. A small alignment of the screening period, i.e., those born from 1960 to 1984, would capture 40% of cases. The data confirm the high endemicity of our geographical area for hepatitis virus infections and underline the need for a tailored screening program according to the regional epidemiology.
