Reliability of liver stiffness measurement in non-alcoholic fatty liver disease: the effects of body mass index
2011
Summary Background Liver stiffness measurement (LSM) using transient elastography (TE) is used to stage fibrosis in patients with liver disease, diagnostic reliability and the factors affecting its performance in patients with non-alcoholic fatty liver disease (NAFLD) are incompletely understood. Aim To assess LSM. Methods Consecutive NAFLD patients (n = 169), assessed by liver biopsy (Kleiner score), anthropometrical, biochemical and metabolic features, underwent LSM using TE with standard M probe. Results Liver stiffness measurement was not reliable in 23 patients (14%) due to obesity. Among patients with a reliable TE, a LSM value >7.25 kPa was the best cut-off for predicting signifi…
Liver stiffness measurement by transient elastography predicts early recovery from acute hepatitis
2010
We read with interest the lead article by Castera and Pinzani,1 particularly the comment regarding the role of transient elastography (TE) in the context of acute hepatitis (AH). The assumption that liver stiffness is determined exclusively by hepatic fibrosis has been challenged by evidence that patients with AH can have high values of liver stiffness measurement (LSM) by TE.2 AH is a suitable model for studying the kinetics of LSM, since inflammation and necrosis increase rapidly and sometimes massively, but may revert with equal speed. We evaluated 92 consecutive patients (mean age 41.8±16.3 years, 71.7% males) with symptomatic AH to assess how LSM was influenced by aetiology, and whethe…
Comparison of Histochemical Staining Methods and Correlation with Transient Elastography in Acute Hepatitis.
2014
<b><i>Objective:</i></b> To compare Masson's trichrome (MT), Sirius red (SR) and orcein staining in acute hepatitis (AH) and to correlate them with<b> </b>transient elastography (TE),<b> </b>a noninvasive method to assess hepatic fibrosis. <b><i>Methods:</i></b> We evaluated liver stiffness by TE in a cohort of 34 consecutive patients and assessed MT-, SR- and orcein-stained biopsies using the METAVIR scoring system and digital image analysis (DIA). <b><i>Results:</i></b> MT and SR both showed severe fibrosis (stage III-IV, DIA = 12.7%). Orcein showed absent or mild fibrosis (stage 0-II, DIA = 4.…
Liver stiffness, a non-invasive marker of liver disease: a core study group report
2010
The ability to evaluate liver stiffness non-invasively in clinical practice by measuring transient elastography using FibroScan® has resulted in considerable interest and enthusiasm. A core study group, organized by the Italian Association for the Study of the Liver, has assessed the usefulness of FibroScan® in the diagnosis and management of liver disease in clinical practice. The group concluded that FibroScan® is a valuable, non-invasive technique and have developed a consensus report form for registering transient elastography results. In this article, we report the findings of the study group.
The severity of steatosis influences liver stiffness measurement in patients with nonalcoholic fatty liver disease
2015
In nonalcoholic fatty liver disease, the influence of severity of steatosis on liver stiffness measurement (LSM) is poorly studied and still debated. We assessed the impact of steatosis severity and its ultrasonographic (US) sign, severe bright liver echo pattern, on LSM values and on transient elastography accuracy for the diagnosis of liver fibrosis in a cohort of consecutive patients with nonalcoholic fatty liver disease. Patients (n = 253) were assessed by clinical, US, and histological (Kleiner score) features. Transient elastography was performed using the M probe. Among patients with low amounts of fibrosis (F0-F1 and F0-F2), median LSM values, expressed in kilopascals, were signific…

Accuracy of Transient Elastography in Assessing Fibrosis at Diagnosis in Naïve Patients With Primary Biliary Cholangitis: A Dual Cut-Off Approach
2021
Background & aims Liver fibrosis holds a relevant prognostic meaning in primary biliary cholangitis (PBC). Non-invasive fibrosis evaluation using vibration-controlled transient elastography (VCTE) is routinely performed. However, there is limited evidence on its accuracy at diagnosis in PBC. We aimed to estimate the diagnostic accuracy of VCTE in assessing advanced fibrosis at disease presentation in PBC. Approach & results We collected data from 167 consecutive treatment-naive PBC patients who underwent liver biopsy(LB) at diagnosis at six Italian centers. VCTE examinations were completed within 12 weeks of LB. Biopsies were scored by two blinded expert pathologists, according to Ludwig sy…
Noninvasive assessment of liver fibrosis in thalassaemia major patients by transient elastography (TE) - lack of interference by iron deposition.
2009
The correlation between liver stiffness, measured by transient elastography, liver fibrosis, using the histological METAVIR score, and iron overload, measured by atomic absorption spectrometry was evaluated in 56 homozygous-b-thalassaemics. Liver stiffness increased proportionally to liver fibrosis staging (r = 0Æ70; P > 0Æ001) independently of liver iron concentration (r = 0Æ01; P = 0Æ932). The area under the receiver-operating characteristic curve for prediction of cirrhosis was 0Æ997 (95% confidence interval [CI]: 0Æ925–1Æ000) with cut-off of 13 kPa with 100% sensitivity (95% CI: 69Æ0–100Æ0) and 95% specificity (95% CI: 84Æ2–99Æ3). Transient elastography is a reliable non-invasive tool f…
Chronic hepatitis C in children is a mild and curable liver disease
2011
Hepatitis C virus (HCV) infection is a major health problem orldwide, but children constitute only a small portion of infected atients. HCV transmission can occur through blood transfusion, nd the incidence of HCV infection was very high in children transused before 1990 for treatment of chronic haematological diseases 1] or other diseases that required blood transfusion [2]. Since he introduction of screening for HCV infection, blood transfusions ave become safe in developed countries, and the residual risk is oday very limited. In developed countries, maternal–fetal transmission has ecome themajor risk factor for HCV in children,with an estimated isk of infection ranging from 2% to 6% [3]…
Predictors of advanced fibrosis in non-cirrhotic non-alcoholic fatty liver disease in Germany
2018
BACKGROUND Advanced fibrosis has been established as the most important predictor of overall mortality in patients with non-alcoholic fatty liver disease (NAFLD). In contrast to cirrhosis, advanced, non-cirrhotic NAFLD is difficult to identify and data from Germany are lacking. AIM To identify clinical factors associated with advanced, non-cirrhotic fibrosis. METHODS Patients were recruited in the prospectively enrolling European NAFLD Registry. Clinical characteristics and the performance of non-invasive surrogate scores compared with vibration-controlled transient elastography are reported. RESULTS Two hundred and sixty-one patients with non-cirrhotic NAFLD on liver biopsy (mean age 51 ye…
