Refining the Baveno VI elastography criteria for the definition of compensated advanced chronic liver disease
2021
Background: The Baveno VI consensus proposed a dual liver stiffness (LS) by transient elastography threshold of <10 and >15 kPa for excluding and diagnosing compensated advanced chronic liver disease (cACLD) in the absence of other clinical signs. Herein, we aimed to validate these criteria in a real-world multicentre study. Methods: We included 5,648 patients (mean age 51 ± 13 years, 53% males) from 10 European liver centres who had a liver biopsy and LS measurement within 6 months. We included patients with chronic hepatitis C (n = 2,913, 52%), non-alcoholic fatty liver disease (NAFLD, n = 1,073, 19%), alcohol-related liver disease (ALD, n = 946, 17%) or chronic hepatitis B (n = 716…
Steatosis affects the performance of liver stiffness measurement for fibrosis assessment in patients with genotype 1 chronic hepatitis C.
2014
Background & Aims: In Chronic Hepatitis C (CHC), the influence of steatosis on liver stiffness measurement (LSM) is still debated. We assessed the impact of steatosis and its ultrasonographical sign – bright liver echo pattern (BLEP) – on LSM values and on transient elastography (TE) accuracy for the diagnosis of liver fibrosis, in a cohort of consecutive patients with Genotype 1 (G1) CHC. Methods: Patients (n = 618) were assessed by clinical, ultrasonographic and histological (Scheuer score) features. TE was performed using the M probe. Results: Male gender (p = 0.04), steatosis as continuous variable (p <0.001), severity of necroinflammation (p = 0.02) and stage of fibrosis (p <0.001) wer…
Comparison of transient elastography and acoustic radiation force impulse for non-invasive staging of liver fibrosis in patients with chronic hepatit…
2011
Transient elastography (TE) is adequate for a diagnosis of cirrhosis, but its accuracy for milder stages of fibrosis is much less satisfactory. The objective of this study was to compare the performance and the discordance rate of acoustic radiation force impulse (ARFI) and TE with liver biopsy in a cohort of chronic hepatitis C (CHC) patients.One hundred thirty-nine consecutive patients with CHC were enrolled in two tertiary centers, and evaluated for histological (Metavir score) and biochemical features. All patients underwent TE and ARFI.TE was unreliable in nine patients (6.5%), while in no cases (0%) were ARFI invalid measurements recorded (P=0.029). By area under receiver operating ch…
Validity criteria for the diagnosis of fatty liver by M probe-based controlled attenuation parameter.
2017
Background & Aims Controlled attenuation parameter (CAP) can be performed together with liver stiffness measurement (LSM) by transient elastography (TE) and is often used to diagnose fatty liver. We aimed to define the validity criteria of CAP. Methods CAP was measured by the M probe prior to liver biopsy in 754 consecutive patients with different liver diseases at three centers in Europe and Hong Kong (derivation cohort, n = 340; validation cohort, n = 414; 101 chronic hepatitis B, 154 chronic hepatitis C, 349 non-alcoholic fatty liver disease, 37 autoimmune hepatitis, 49 cholestatic liver disease, 64 others; 277 F3-4; age 52 ± 14; body mass index 27.2 ± 5.3 kg/m2). The primary outco…
Range of Normal Liver Stiffness and Factors Associated With Increased Stiffness Measurements in Apparently Healthy Individuals
2018
Background & Aims: Transient elastography (TE) is a noninvasive technique used to measure liver stiffness to estimate the severity of fibrosis. The range of liver stiffness measurements (LSMs) in healthy individuals is unclear. We performed a systematic review to determine the range of LSMs, examined by TE, in healthy individuals and individuals who are susceptible to fibrosis. Methods: We collected data from 16,082 individuals, in 26 cohorts, identified from systematic searches of Embase, Ovid MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews for studies of liver stiffness measurements. Studies analyzed included apparently healthy adul…
Body Mass Index and Liver Stiffness Affect Accuracy of Ultrasonography in Detecting Steatosis in Patients With Chronic Hepatitis C Virus Genotype 1 I…
2013
Background & Aims: Few studies have evaluated the accuracy of ultrasonography in detecting steatosis in patients with chronic hepatitis C. We assessed its accuracy in detecting steatosis and factors that affect its diagnostic performance in consecutive patients with chronic hepatitis C virus genotype 1infection. Methods: We analyzed data from 515 patients with chronic hepatitis C, confirmed by liver biopsy, assessing anthropometric, biochemical, metabolic, virologic, and ultrasonography features. Transient elastography was performed to measure liver stiffness. Steatosis was identified with ultrasonography based on detection of a bright liver echo pattern. Results: Ultrasonography identified…
An evaluation of transient elastography in the discrimination of HBeAg-negative disease from inactive hepatitis B carriers
2009
Summary. Liver biopsy is frequently required in HBeAg-negative disease to determine the stage of fibrosis. It can be difficult to distinguish cohorts with undetectable HBeAg who may have varying degrees of fibrosis due to different stages of disease. We have assessed the utility of transient elastography (TE) to evaluate differences in HBeAg-negative patients. A total of 220 HBsAg-positive individuals were studied: 125 (group 1) had an inactive HBsAg carrier state and 95 (group 2) were HBeAg-negative, anti-HBe-positive patients with persistently or intermittent elevation of alanine aminotransferase (ALT) and/or HBV DNA >105 copies/mL. Mean stiffness was 4.83 ± 1.2 kPa in group 1 vs 8.53 ± …
Liver stiffness measurement by vibration-controlled transient elastography improves outcome prediction in primary biliary cholangitis
2022
BACKGROUND & AIMS: Liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) has been shown to predict outcomes of patients with primary biliary cholangitis (PBC) in small-size studies. We aimed to validate the prognostic value of LSM in a large cohort study. METHODS: We performed an international, multicentre, retrospective follow-up study of 3,985 patients with PBC seen at 23 centres in 12 countries. Eligibility criteria included at least 1 reliable LSM by VCTE and a follow-up ≥ 1 year. Independent derivation (n = 2,740) and validation (n = 568) cohorts were built. The primary endpoint was time to poor clinical outcomes defined as liver-related complications,…
Early changes in dynamic biomarkers of liver fibrosis in hepatitis C virus-infected patients treated with sofosbuvir
2016
Abstract Background Chronic hepatitis C is a major cause of liver-associated mortality caused by decompensated cirrhosis and hepatocellular carcinoma. With the approval of sofosbuvir, therapeutic efficacy has markedly increased. Early changes in non-invasive biomarkers of liver fibrosis under effective antiviral therapy are widely unknown. Aim To evaluate early changes of fibrosis markers determined by enhanced liver fibrosis (ELF) scores and liver stiffness measurement (FibroScan®) in patients treated with sofosbuvir. Methods A total of 32 hepatitis C patients treated prospectively with sofosbuvir were included. The ELF-panel and FibroScan measurements were performed at baseline, week 4, e…
FibroScan Identifies Patients With Nonalcoholic Fatty Liver Disease and Cardiovascular Damage
2020
BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) are closely associated, and liver fibrosis has been related to macrovascular complications. We examined whether liver fibrosis, diagnosed by FibroScan® , correlates with chronic vascular complications in a cohort of T2DM. METHODS: We recruited 394 outpatients with T2DM attending five Italian diabetes centres who underwent liver ultrasonography (US), FibroScan® and extensive evaluation of macrovascular and microvascular diabetic complications. RESULTS: Steatosis by US was present in 89%. Almost all patients (96%) were on hypoglycaemic drugs, 58% had at least one chronic vascular complication,…
