Hepatocellular Cancer Surveillance in Patients with Advanced Chronic Liver Disease.

Background: Patients with advanced chronic liver disease (ACLD) are at high risk of developing hepatocellular carcinoma (HCC). Therefore, biannual surveillance is recommended. This large-scale multicenter study aimed to stratify the risk of HCC development in ACLD.

Insulin-like growth factor-1 in cirrhosis is linked to hepatic dysfunction and fibrogenesis and predicts liver-related mortality.

Background And Aims: We aimed to characterise insulin-like growth factor-1 (IGF-1) signalling in patients with advanced chronic liver disease (ACLD).

Methods: Consecutive patients undergoing hepatic venous pressure gradient [HVPG] measurement were prospectively included. Clinical stages were defined as follows: probable ACLD (pACLD): liver stiffness ≥10 kPa and HVPG ≤5 mmHg, S0: mild PH (HVPG 6-9 mmHg), S1: clinically significant PH (CSPH), S2: CSPH with varices, S3: past variceal bleeding, S4: past/current non-bleeding hepatic decompensation and S5: further decompensation.

The deep abdominal ultrasound transducer (DAX) increases the success rate and diagnostic accuracy of shear wave elastography for liver fibrosis assessment in patients with obesity-A prospective biopsy-controlled study.

Background: Obesity impacts the diagnostic accuracy of shear wave elastography (SWE). A deep abdominal ultrasound transducer (DAX) capable of point (pSWE) and two-dimensional (2D)-SWE has recently been introduced to address this issue.

Methods: We performed a prospective study in a cohort of mostly patients with obesity undergoing liver biopsy with a high prevalence of metabolic dysfunction-associate steatotic liver disease (MASLD).

Post-treatment LSM rather than change during treatment predicts decompensation in patients with cACLD after HCV cure.

Background & Aims: Baveno VII has defined a clinically significant (i.e., prognostically meaningful) decrease in liver stiffness measurement (LSM) in cACLD as a decrease of ≥20% associated with a final LSM <20 kPa or any decrease to <10 kPa.

Validation of Baveno VII criteria and other non-invasive diagnostic algorithms for clinically significant portal hypertension in hepatitis delta.

Background & Aims: Non-invasive tests (NITs) for clinically significant portal hypertension (CSPH) require validation in patients with hepatitis D virus (HDV)-related compensated advanced chronic liver disease (cACLD). Therefore, we aimed to validate existing NIT algorithms for CSPH in this context.

Methods: Patients with HDV-cACLD (LSM ≥10 kPa or histological METAVIR F3/F4 fibrosis) who underwent paired HVPG and NIT assessment at Medical University of Vienna or Hannover Medical School between 2013 and 2023 were retrospectively included.

Lower free triiodothyronine (fT3) levels in cirrhosis are linked to systemic inflammation, higher risk of acute-on-chronic liver failure, and mortality.

Background & Aims: Advanced chronic liver disease (ACLD) may affect thyroid hormone homeostasis. We aimed to analyze the pituitary-thyroid axis in ACLD and the prognostic value of free triiodothyronine (fT3).

Methods: Patients with ACLD (liver stiffness measurement [LSM] ≥10 kPa) undergoing hepatic venous pressure gradient (HVPG) measurement between June 2009 and September 2022 and available fT3 levels were included.

Two-dimensional shear wave elastography (ElastQ) accurately rules out liver fibrosis and rules in advanced chronic liver disease across liver disease etiologies: a prospective multicenter study.

Purpose: This study evaluated ElastQ, a two-dimensional shear wave elastography (2D-SWE) technique, for the non-invasive assessment of liver fibrosis risk using liver stiffness measurement (LSM). The aim was to determine its diagnostic accuracy and establish LSM cutoffs for clinical risk stratification.

Methods: A prospective multicenter study was conducted, employing vibration-controlled transient elastography (VCTE) as a reference standard.

Material And Methods:  A total of 110 cirrhotic patients were prospectively included.

An impaired pituitary-adrenal signalling axis in stable cirrhosis is linked to worse prognosis.

Background & Aims: Inadequate adrenal function has been described in patients with cirrhosis. We investigated (i) the pituitary-adrenal axis at different clinical stages and (ii) the clinical impact of decreased serum cortisol levels in stable patients with advanced chronic liver disease (ACLD).

Methods: We included 137 outpatients with ACLD undergoing hepatic venous pressure gradient (HVPG) measurement in the prospective VICIS study (NCT03267615).

Dynamics in Liver Stiffness Measurements Predict Outcomes in Advanced Chronic Liver Disease.

Background & Aims: Liver stiffness measurements (LSMs) provide an opportunity to monitor liver disease progression and regression noninvasively. We aimed to determine the prognostic relevance of LSM dynamics over time for liver-related events and death in patients with chronic liver disease.

Methods: Patients with chronic liver disease undergoing 2 or more reliable LSMs at least 180 days apart were included in this retrospective cohort study and stratified at baseline (BL) as nonadvanced chronic liver disease (non-ACLD, BL-LSM < 10 kPa), compensated ACLD (cACLD; BL-LSM ≥ 10 kPa), and decompensated ACLD.

Etiological cure prevents further decompensation and mortality in patients with cirrhosis with ascites as the single first decompensating event.

Background And Aims: Removal/suppression of the primary etiological factor reduces the risk of decompensation and mortality in compensated cirrhosis. However, in decompensated cirrhosis, the impact of etiologic treatment is less predictable. We aimed to evaluate the impact of etiological treatment in patients with cirrhosis who developed ascites as single index decompensating event.

Dysregulated biomarkers of innate and adaptive immunity predict infections and disease progression in cirrhosis.

Background & Aims: Cirrhosis-associated immune dysfunction (CAID) affects both innate and adaptive immunity. This study investigated the complement system, immunoglobulins, and acute-phase proteins and their prognostic relevance in patients with advanced chronic liver disease (ACLD).

Methods: Patients with ACLD (hepatic venous pressure gradient [HVPG] ≥6 mmHg) but without acute decompensation/infections were characterised by HVPG and by clinical EASL stages: compensated (cACLD; S0-2) decompensated ACLD (dACLD) with previous variceal bleeding (S3), non-bleeding decompensation (S4), or further decompensation (S5).

Low mortality despite temporary liver dysfunction in severe courses of acute hepatitis E.

Background: Hepatitis E virus (HEV) infection can cause severe viral hepatitis and eventually liver failure. We aim to provide novel data on the epidemiology and the course of HEV infections from Q1/2008 to Q3/2018 at the Vienna General Hospital.

Methods: Of the 88,945 people tested, we identified HEV-IgM positive (+) or HEV-PCR (+) patients and retrospectively collated information on the course of infection from patient records.

Alcohol Abstinence Improves Prognosis Across All Stages of Portal Hypertension in Alcohol-Related Cirrhosis.

Background And Aims: Alcohol-related liver disease is a leading cause of liver-related mortality. The effect of alcohol abstinence on the natural history of alcohol-related cirrhosis across distinct stages of portal hypertension has not been thoroughly investigated. In this study, we assessed the clinical implications of abstinence in patients with alcohol-related cirrhosis and clinically significant portal hypertension.
