Background and Aims: Treatment indications for chronic hepatitis B (CHB) differ among recommendations by European Association for the Study of the Liver (EASL), American Association for the Study of Liver Diseases (AASLD) and World Health Organization (WHO). We aimed to assess treatment eligibility and linkage to therapy at a large tertiary care center., Methods: All CHB patients who were evaluated for treatment at the Vienna General Hospital between January 2010 and December 2020 were retrospectively included. Clinical, virological, and long-term treatment efficacy data were analyzed., Results: A total of 751 CHB patients were included (53.3% male; median age: 39.5 years; HBeAg-positive: 10.8%). The median Hepatitis B Virus (HBV)-DNA and HBsAg levels were 569 (68-11,750) IU/mL and 3467.65 (620.05-11,935.43) IU/mL, respectively. Overall, 9.2% of patients had severe fibrosis/cirrhosis, and 5.7% were coinfected with hepatitis D virus (HDV), which was highly prevalent in cirrhosis. According to the recent EASL nomenclature, 3.2% of patients had HBeAg-positive chronic infection, 7.6% had HBeAg-positive chronic hepatitis, 58.9% had HBeAg-negative chronic infection, and 30.4% had HBeAg-negative chronic hepatitis. At the time of evaluation, 36.4% had HBV-DNA >2000 IU/mL, and 37.3% showed alanine aminotransferase >40 U/L. Ultimately, 26.9% (EASL), 29.0% (AASLD) and 23.4% (WHO) met the treatment criteria. Treatment was initiated in most patients, mainly with tenofovir (61.8%) or entecavir (34.9%). Treatment efficiently suppressed HBV-DNA in all patients; however, HBsAg loss was observed only in 2.8% at 5 years of therapy., Conclusions: Severe fibrosis/cirrhosis was found in 9.2% of CHB patients at presentation, and 23.4%-29.5% met current treatment recommendations with a high treatment uptake of 79.8%-89.2% among eligible patients., (© 2023 The Authors.

Background: Hepatitis D virus (HDV) coinfection aggravates the course of hepatitis B virus (HBV). The prevalence of HDV in Austria is unknown., Objective: This national study aimed at (i) recording the prevalence of HDV-infection in Austria and (ii) characterizing the "active" HDV cohort in Austria., Methods: A total of 10 hepatitis treatment centers in Austria participated in this multicenter study and retrospectively collected their HDV patients between Q1/2010 and Q4/2020. Positive anti-HDV and/or HDV-RNA-polymerase chain reaction (PCR) results were retrieved from local database queries. Disease severity was assessed by individual chart review. Viremic HDV patients with clinical visits in/after Q1/2019 were considered as the "active" HDV cohort., Results: A total of 347 anti-HDV positive patients were identified. In 202 (58.2%) patients, HDV-RNA-PCR test was performed, and 126/202 (62.4%) had confirmed viremia. Hepatocellular carcinoma was diagnosed in 7 (5.6%) patients, 7 (5.6%) patients underwent liver transplantation, and 11 (8.7%) patients died during follow-up. The "active" Austrian HDV cohort included 74 (58.7%) patients: Evidence for advanced chronic liver disease (ACLD, i.e., histological F3/F4 fibrosis, liver stiffness ≥10 kPa, varices, or hepatic venous pressure gradient ≥6 mmHg) was detected in 38 (51.4%) patients, including 2 (5.3%) with decompensation (ascites/hepatic encephalopathy). About 37 (50.0%) patients of the "active" HDV cohort had previously received interferon treatment. Treatment with the sodium-taurocholate cotransporting polypeptide inhibitor bulevirtide was initiated in 20 (27.0%) patients., Conclusion: The number of confirmed HDV viremic cases in Austria is low (<1% of HBV patients) but potentially underestimated. Testing all HBV patients will increase the diagnostic yield. More than half of viremic HDV patients had ACLD. Improved HDV testing and workup strategies will facilitate access to novel antiviral therapies., (© 2021 The Authors.

Introduction: Recently, based on data from the PREDICT study, the European Foundation for the Study of Chronic Liver Failure (EF-CLIF) consortium proposed pathophysiological/prognostic groups in hospitalized patients with cirrhosis: stable decompensated cirrhosis (SDC), unstable decompensated cirrhosis (UDC), pre-acute-on-chronic liver failure (pre-ACLF), and ACLF. We evaluated the outcomes of these subgroups in a real-life cohort of hospitalized patients with cirrhosis., Methods: Patients with cirrhosis developing first AD between 09/2010 and 12/2017 at the Vienna General Hospital were evaluated for this retrospective analysis., Results: Two hundred and ten patients with cirrhosis (aged 57.6 ± 11.8 years) including n = 45 (21.4%) SDC, n = 100 (47.6%) UDC, n = 28 (13.3%) pre-ACLF, and n = 37 (17.6%) with ACLF were considered. The proposed AD subgroups discriminated between patients with favorable (1-year mortality: SDC: 6.7% and UDC: 19.6%) and dismal prognosis (90-day mortality: pre-ACLF: 42.9%). Interestingly, systemic inflammation gradually increased (e.g., C-reactive protein, SDC: 0.9 mg/dl, vs. UDC: 2.0 mg/dl vs. pre-ACLF: 3.2 mg/dl, p < 0.001) while renal function was progressively deteriorating (creatinine levels, SDC: 0.8 mg/dl vs. UDC: 0.9 mg/dl vs. pre-ACLF: 1.2 mg/dl, p < 0.001) across prognostic subgroups in patients with cirrhosis., Discussion: The recently proposed pathophysiological/prognostic EF-CLIF subgroups are also reproduceable in a real-life cohort of cirrhotic patients. As ACLF is a common and important complication, patients at risk of pre-ACLF at index AD should be evaluated and if disease proceeds, been treated early and aggressively to avoid excessive mortality., (© 2021 The Authors.
