Background And Aims: The performance of non-invasive liver tests (NITs) is known to vary across settings and subgroups. We systematically evaluated whether the performance of three NITs in detecting advanced fibrosis in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) varies with age, sex, body mass index (BMI), type 2 diabetes mellitus (T2DM) status or liver enzymes.
Methods: Data from 586 adult LITMUS Metacohort participants with histologically characterised MASLD were included.
Unlike for advanced liver fibrosis, the practical rules for the early non-invasive diagnosis of cirrhosis in NAFLD remain not well defined. Here, we report the derivation and validation of a stepwise diagnostic algorithm in 1568 patients with NAFLD and liver biopsy coming from four independent cohorts. The study algorithm, using first the elastography-based tests Agile3+ and Agile4 and then the specialized blood tests FibroMeter and CirrhoMeter, provides stratification in four groups, the last of which is enriched in cirrhosis (71% prevalence in the validation set).

Data from this first international cross-sectional survey of individuals with NAFLD/NASH were used to identify correlates of both unawareness about fibrosis stage and its association with adherence to lifestyle adjustments.
Methods: Adults with NAFLD/NASH registered on the platform Carenity were invited to participate in an online 20-min, six-section survey in Canada, France, Germany, Italy, Spain and the United Kingdom to describe their experience with NAFLD/NASH and its care (N = 1411).
Background & Aims: Previous studies on the prognostic significance of non-invasive liver fibrosis tests in non-alcoholic fatty liver disease (NAFLD) lack direct comparison to liver biopsy. We aimed to evaluate the prognostic accuracy of fibrosis-4 (FIB4) and vibration-controlled transient elastography (VCTE), compared to liver biopsy, for the prediction of liver-related events (LREs) in NAFLD.
Methods: A total of 1,057 patients with NAFLD and baseline FIB4 and VCTE were included in a multicenter cohort.
Background & Aims: Non-alcoholic steatohepatitis (NASH) is a chronic, progressive fibrotic liver disease that can lead to cirrhosis. While liver biopsy is considered the reference standard for the histologic diagnosis of NASH and staging of fibrosis, its use in clinical practice is limited. Non-invasive tests (NITs) are increasingly being used to identify and stage liver fibrosis in patients with NASH, and several can assess liver-related outcomes.
View Article and Find Full Text PDFBackground And Aims: Non-alcoholic steatohepatitis (NASH) is a chronic disease that can progress to end-stage liver disease (ESLD). A large proportion of early-stage NASH patients remain undiagnosed compared to those with advanced fibrosis, who are more likely to receive disease management interventions. This study estimated the disease burden and economic impact of diagnosed NASH in the adult population of France, Germany, Italy, Spain and the United Kingdom in 2018.

Scope: A prospective multicenter study was conducted in treatment-naive patients with hepatitis B e antigen (HBeAg)-positive CHB. All patients received telbivudine (600 mg/day) until Week 24.
Aim: To achieve an evidence-based conclusion regarding the safety and efficacy of telbivudine during pregnancy.
Methods: A pooled analysis of data from a literature search reported 1739 pregnancy outcomes (1673 live births) from 1725 non-overlapping pregnant women treated with telbivudine. The prevalence of live birth defects (3.
Introduction: The long-term goal of chronic hepatitis B (CHB) treatment is improvement of liver disease and prevention of cirrhosis. The aim of this study was to assess whether prolonged telbivudine treatment improves liver inflammation and fibrosis. The primary objective was to evaluate the proportion of patients with absence/minimal inflammation (Knodell necroinflammatory score ≤3) on liver biopsy at Year 5.

Methods: This was a randomized, open-label study comparing the viral kinetics in 46 hepatitis B e antigen-positive patients during 12-week treatment with telbivudine monotherapy, tenofovir monotherapy or the combination of telbivudine plus tenofovir. A standard biphasic mathematical model was used to compare hepatitis B virus (HBV) DNA decay parameters.
Background & Aims: This study investigated the antiviral efficacy and safety of telbivudine in combination with pegylated interferon (PegIFN) alpha-2a in chronic hepatitis B (CHB) patients.
Methods: This was a randomized, open-label, multicentre study, in treatment-naïve patients with HBeAg-positive CHB, comparing the efficacy and safety of telbivudine in combination with PegIFN alpha-2a with telbivudine monotherapy and PegIFN alpha-2a monotherapy. The study was terminated early due to increased rates of peripheral neuropathy in the combination-therapy group.
Purpose: The burden of chronic hepatitis B infection is high in China, where prevalence exceeds 7 %. This was a randomized, double-blinded, phase III study of the efficacy and safety of telbivudine and lamivudine treatment at 104 weeks in Chinese patients with chronic hepatitis B.
Methods: Hepatitis B e antigen-positive (n = 290) and -negative (n = 42) adults with nucleoside analog-naïve compensated chronic hepatitis B were randomized to receive telbivudine 600 mg/day or lamivudine 100 mg/day for 104 weeks.
Background & Aims: There is a close relationship between chronic hepatitis B virus infection and chronic renal disease. We analyzed changes in renal function using different markers of glomerular filtration rate (GFR) in multiple studies of telbivudine treatment of patients with chronic hepatitis B virus infection.
Methods: We used serum creatinine-based equations (ie, Cockcroft-Gault, Modification of Diet in Renal Disease, and Chronic Kidney Disease Epidemiology Collaboration) to estimate GFR (eGFR) in adults with chronic hepatitis B virus infection and compensated liver disease who participated in a phase III, randomized, double-blind study comparing the efficacy and safety of telbivudine (600 mg/d) and lamivudine (100 mg/d) for 2 years (the GLOBE study) and in long-term extension studies (4-6 years), as well as in patients with decompensated cirrhosis (2 years).
Background And Aims: The Roadmap concept is a therapeutic framework in chronic hepatitis B for the intensification of nucleoside analogue monotherapy based on early virologic response. The efficacy and safety of this approach applied to telbivudine treatment has not been investigated.
Methods: A multinational, phase IV, single-arm open-label study (ClinicalTrials.
Purpose: Lamivudine (LAM) resistance is common on lamivudine monotherapy for chronic hepatitis B. This study examined the safety and efficacy of telbivudine (LDT) given with adefovir (ADV) versus ADV monotherapy in patients with chronic, lamivudine-resistant HBV infection.
Methods: An open-label, 96 week study with planned recruitment of 150 HBeAg-positive, lamivudine-experienced Asian patients with a confirmed YMDD resistance mutation, randomized 1:1 to receive ADV alone or with LDT.
Objectives: To assess simplified maintenance regimens containing dual antiretroviral drugs in patients with controlled human immunodeficiency virus type 1 infection.
Methods: A non-inferiority, randomized, multicentre, open-label trial was performed in 24 AIDS clinical centres in France randomizing 143 patients [treated for >or=6 months, plasma viral load (pVL) <50 copies/mL, no prior history of treatment failure] to receive a two-drug regimen [tenofovir disoproxil fumarate (tenofovir DF) and efavirenz] or to maintain a three-drug treatment (tenofovir DF, lamivudine and efavirenz). The main outcome measure was the success rate (percentage of patients with pVL <50 copies/mL without treatment modifications) at week 48.
Background/aims: Data on the efficacy of adefovir dipivoxil (ADV) in elderly and cirrhotic patients with lamivudine-resistant (LAM-R) chronic hepatitis B are scarce. This retrospective cohort study evaluated the safety and efficacy of ADV in this specific patient population.
Methods: Sixty-eight cirrhotic LAM-R patients, of whom 19 (27.
Drug resistance is an increasing problem in the treatment of HIV infection. Tenofovir has been shown to inhibit HIV replication even with thymidine-associated resistance mutations (TAMs) if they are limited to two or less. Double-dose of tenofovir disoproxil fumarate (TDF) (600 mg QD) was used to determine weather the drug could be virologically effective in patients harbouring HIV-strains resistant to nucleoside analogues (NRTI).
