The updated EASL Clinical Practice Guidelines on the management of hepatitis B virus (HBV) infection provide comprehensive, evidence-based recommendations for its management. Spanning ten thematic sections, the guidelines address diagnostics, treatment goals, treatment indications, therapeutic options, hepatocellular carcinoma surveillance, management of special populations, HBV reactivation prophylaxis, post-transplant care, HBV prevention strategies, and finally address open questions and future research directions. Chronic HBV remains a global health challenge, with over 250 million individuals affected and significant mortality due to cirrhosis and hepatocellular carcinoma. These guidelines emphasise the importance of early diagnosis, risk stratification based on viral and host factors, and tailored antiviral therapy. Attention is given to simplified algorithms, vaccination, and screening to support global HBV elimination targets. The guidelines also discuss emerging biomarkers and evolving definitions of functional and partial cure. Developed through literature review, expert consensus, and a Delphi process, the guidelines aim to equip healthcare providers across disciplines with practical tools to optimise HBV care and outcomes worldwide.

Circulating tumor cells (CTC) have shown promise in predicting the outcomes of adjuvant treatments for several malignancies. The clinical significance of CTC in predicting the efficacy of tyrosine kinase inhibitor (TKI) administration in patients with hepatocellular carcinoma (HCC) was unclear.

A total of 429 patients who underwent liver transplantation for HCC had provided 335 preoperative and 373 postoperative blood samples that could be used for CTC detection (pre-CTC and post-CTC). The association of the pre-CTC and post-CTC findings with the efficacy of TKI administration was assessed. Additionally, CTC surveillance was performed in 27 patients during TKI administration.

Patients with detectable post-CTC, instead of pre-CTC, showed a significantly longer time to recurrence when receiving a TKI after liver transplantation for HCC (hazard ratio 0.57; P = 0.042). Whereas patients without detectable post-CTC did not benefit from the TKI administration (P = 0.270). Furthermore, we also found that patients who persistently harbored CTC during TKI administration showed significantly higher early recurrence rates (≤1 year; 40% vs. 5.9%, P < 0.001) and a shorter time to recurrence (HR 7.03; P < 0.001) than those whose CTC status switched from positive to negative. In addition, longitudinal CTC monitoring demonstrated that CTC tended to reflect drug resistance during TKI administration.

The postoperative CTC level could predict the efficacy of TKI treatment for HCC patients after liver transplantation. Dynamic monitoring for CTC during treatment could sensitively reflect the response to the TKI, the development of drug resistance, and foresee tumor recurrence.

Hepatitis B virus (HBV) remains a leading etiology for liver transplantation (LT). In a large cohort of HBsAg-positive patients, this study evaluates long-term patient and graft survival after LT over the past 30 years while analyzing trends and outcomes following waiting list (WL) inclusion over the last 15 years.

HBsAg-positive patients who underwent transplantation between 1991 and 2020 and were waitlisted from 2006 to 2020 at Padua Hospital were included in the analysis. Patients were stratified according to hepatitis delta virus (HDV) coinfection, transplant indication (decompensated cirrhosis vs. hepatocellular carcinoma (HCC)), and WL inclusion period.

Among 321 HBsAg-positive LT recipients (31.5% HDV-coinfected, 46.4% HCC), 1-year and 5-year patient/graft survival rates were 87.6%/86.7% and 82.6%/82.2%, respectively. From 2006 to 2020, 284 HBsAg-positive patients were waitlisted (32.6% HDV-coinfected), with a significantly higher prevalence of HCC compared to non-HBV patients (p = 0.008). High-barrier nucleos(t)ide analogues (hbNUCs) significantly reduced mortality (p = 0.041) and improved survival post-WL inclusion (p = 0.007). Survival rates were consistent regardless of LT indication, HDV coinfection, or WL inclusion period. Post-transplant prophylaxis predominantly involved immunoglobulins (HBIG) + NUCs, resulting in only two cases of HBV reactivation, both clinically inconsequential.

Over the past 30 years, HBV has remained a consistent indication for LT at our center. Thanks to hbNUCs, WL outcomes have improved and HCC has become the main indication for LT.

Conflicting data exist regarding optimal prophylaxis for HBV recurrence (HBV-R) after liver transplantation (LT), particularly in patients with hepatocellular carcinoma (HCC). We assessed current practices for HBV-R prophylaxis in Italy, evaluating rates, risk factors, and the clinical impact of HBV-R and HCC-R.

We performed a multicentric, retrospective study involving 20 Italian LT centers. All patients who underwent LT for HBV-related liver diseases between 2010 and 2021 were included. Logistic regression was used to identify predictors of HBV-R and HCC-R. Survival curves were estimated with the Kaplan-Meier method and compared with the log-rank test.

We included 1,205 LT recipients (60.8% with HCC). HBV prophylaxis was prescribed in 99.7% of recipients, mostly with lifelong hepatitis B immunoglobulin+nucleos(t)ide analogues (HBIG+NUCs) (83.9%). Rates of HBV-R were 2.1% and 3.1% in patients transplanted without and with HCC, respectively. Median times from LT were 60 [9.5-77.5] and 5.5 [1-13] months, respectively. Recipients on lifelong HBIG+NUCs experienced lower rates of HBV-R than those in whom HBIG was withdrawn, used only during LT, or in those who received NUCs alone (2.3% vs. 6.2% vs. 1.9% vs. 8%, respectively; p = 0.042). In recipients with HCC, HCC-R rate was 10.8% (median time from LT: 18 months). At multivariate analysis, HBV-R (odds ratio [OR] 10.329; 95% CI 3.665-29.110), Child-Pugh C (OR 3.519; 95% CI 1.305-9.484), and microvascular invasion (OR 3.088; 95% CI 1.692-5.634) were independently associated with HCC-R. Five-year survival was lower in recipients who experienced HCC-R (32.5% vs. 92.4% in those who did not; p <0.001).

In Italy, HBV prophylaxis is mostly based on lifelong HBIG+NUCs. HBV-R was rare and not associated with survival in patients transplanted for decompensated cirrhosis. In patients transplanted for HCC, HBV-R was independently associated with HCC-R. The clinical implications of these findings deserve further investigation.

In Italy, the combination of high-barrier nucleos(t)ide analogues and hepatitis B immunoglobulins remains the most widely used regimen for antiviral prophylaxis following liver transplantation for HBV-related liver disease. Hepatitis B recurrence after liver transplantation is a rare event and not associated with reduced survival. In transplant recipients with hepatocellular carcinoma, HBV recurrence was independently associated with hepatocellular carcinoma recurrence, though this may simply reflect an epiphenomenon without any causal relationship.

Hepatitis B immunoglobulin (HBIG) in combination with a potent nucleos(t)ide analog is considered the standard of care for prophylaxis against hepatitis B virus (HBV) reinfection after liver transplantation for HBV-associated disease.

To evaluate patients' satisfaction, preferences, and requirements for subcutaneous (SC), intramuscular (IM), and intravenous (IV) HBIG treatments.

A self-completion, cross-sectional, online, 22-question survey was conducted to examine perceptions and satisfaction with current HBIG treatment in adults receiving HBIG treatment following liver transplantation for HBV-associated disease in France, Italy, and Turkey. Hypothetical HBIG products with different administration modes were evaluated using target product profile assessment and a conjoint (trade-off) exercise.

Ninety patients were enrolled; 32%, 17%, and 51% were SC, IM, and IV HBIG users, respectively. Mean duration of treatment was 36.2 months. SC HBIG had the least negative impact on emotional well-being and social life and was perceived as the most convenient, easiest to administer, least painful, and had the highest self-rating of treatment compliance. More IM HBIG users than SC or IV HBIG users reported that administration frequency was excessive (67%, 28%, and 28%, respectively). In the target product profile assessment, 76% of patients were likely to use hypothetical SC HBIG. In the conjoint exercise, administration route, frequency, and duration were key drivers of treatment preferences.

Ease, frequency, duration, and side effects of HBIG treatment administration were key drivers of treatment preferences, and SC HBIG appeared advantageous over IM and IV HBIG for administration ease, convenience, and pain. A hypothetical SC HBIG product elicited a favorable response. Patient demographics, personal preferences, and satisfaction with HBIG treatment modalities may influence long-term treatment compliance.

The use of nucleos(t)ide analogs (NAs) with a high genetic barrier to resistance, namely entecavir and tenofovir, has improved the efficacy of antiviral prophylaxis against hepatitis B virus (HBV) recurrence after liver transplantation (LT). However, the optimal duration and dosage of hepatitis B immunoglobulin (HBIG) administration, particularly in patients transplanted for HBV and hepatitis D virus (HDV) coinfection, remains controversial.

We evaluated 28 patients transplanted for HBV/HDV cirrhosis. After LT, each patient received a fixed scheme of low-dose HBIG plus NA for 6 mo post-LT and then continued with long-term NA prophylaxis (entecavir: 8, tenofovir: 20 patients).

During 72 mo of follow-up, reappearance of hepatitis B surface antigen at low titers was observed in 1 (3.6%) patient at 33 mo after HBIG discontinuation, which became negative after a single dose of HBIG 1000 IU/L, whereas both serum HBV DNA and HDV RNA remained persistently undetectable and without any clinical or biochemical evidence of HBV/HDV recurrence.

We showed for the first time the efficacy of a short, fixed scheme of low-dose HBIG plus NA followed by long-term NA monoprophylaxis against HBV/HDV recurrence after LT, although careful follow-up is needed after HBIG discontinuation, whereas further larger studies are needed to confirm these findings.
