Benign focal liver lesions: spectrum of findings on SonoVue-enhanced pulse-inversion ultrasonography.
2005
The prevalence of benign focal liver lesions (BFLL) is high both in the general population and in patients with known malignancies. The gray-scale ultrasound (US) technique is usually the first-line imaging modality used in the radiological workup of such lesions, but unfortunately it lacks specificity. Furthermore, Doppler examination may often be unsatisfactory owing to motion artefacts, or when small or deeply located lesions are evaluated. Recently, microbubble-based contrast agents used in combination with gray-scale US techniques, which are very sensitive to nonlinear behavior of microbubbles, have led to a better depiction of both microvasculature and macrovasculature of focal hepati…
Validity and reliability of the Italian version of the Chronic Liver Disease Questionnaire (CLDQ-I) for the assessment of health-related quality of l…

Background.: The Chronic Liver Disease Questionnaire is a specific health-related quality of life assessment designed for patients with liver diseases. Aim.: The aim of this paper is to report on the validity, reliability and sensitivity to change of the Italian version (Chronic Liver Disease Questionnaire-I) in subjects with HCV infection. Subjects.: The Chronic Liver Disease Questionnaire-I was administered to 350 subjects with HCV infection together with the World Health Organization Quality of Life Assessment, abbreviated version, a generic quality of life assessment. Methods.: The instrument was translated from English, backtranslated and reviewed in focus groups in the framework of a …
The global, regional, and national burden of cirrhosis by cause in 195 countries and territories, 1990-2017 : a systematic analysis for the Global Bu…
2020
Background\ud \ud Cirrhosis and other chronic liver diseases (collectively referred to as cirrhosis in this paper) are a major cause of morbidity and mortality globally, although the burden and underlying causes differ across locations and demographic groups. We report on results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 on the burden of cirrhosis and its trends since 1990, by cause, sex, and age, for 195 countries and territories.\ud \ud \ud \ud Methods\ud \ud We used data from vital registrations, vital registration samples, and verbal autopsies to estimate mortality. We modelled prevalence of total, compensated, and decompensated cirrhosis on the bas…
Hepatocellular Carcinoma and Non-Alcoholic Fatty Liver Disease: From a Clinical to a Molecular Association
2009
Hepatocellular carcinoma (HCC) is the most frequent primary neoplasm of the liver, and is the fourth most common malignancy worldwide. It is also the third leading cause of cancer-related deaths. Most cases of HCC develop on a pre-existing chronic liver disease, usually due to hepatitis C virus (HCV), hepatitis B virus (HBV), or alcohol. However, between 15% and 50% of HCC develops in the absence of a known etiology of liver disease, and different lines of evidence identify in non-alcoholic fatty liver disease (NAFLD) a possible relevant risk factor for occurrence of HCC. Insulin resistance (IR), steatosis, oxidative stress and imbalances in adipokine/cytokine interplay, the most important …
Is physician assessment of alcohol consumption useful in predicting risk of severe liver disease among people with HIV and HIV/HCV co-infection?
2019
AbstractBackgroundAlcohol consumption is a known risk factor for liver disease in HIV-infected populations. Therefore, knowledge of alcohol consumption behaviour and risk of disease progression associated with hazardous drinking are important in the overall management of HIV disease. We aimed at assessing the usefulness of routine data collected on alcohol consumption in predicting risk of severe liver disease (SLD) among people living with HIV (PLWHIV) with or without hepatitis C infection seen for routine clinical care in Italy.MethodsWe included PLWHIV from two observational cohorts in Italy (ICONA and HepaICONA). Alcohol consumption was assessed by physician interview and categorized ac…
The Effects of Sodium Nitroprusside-Induced Hypotension on Splanchnic Perfusion and Hepatocellular Integrity
1999
UNLABELLED The purpose of our study was to investigate the effects of sodium nitroprusside-induced hypotension on splanchnic perfusion and hepatocellular integrity. Thirty patients undergoing radical prostatectomy were allocated randomly to a sodium nitroprusside (SNP) or control group (control). Regional pco2 was measured using gastric tonometry, and the regional to arterial difference in partial pressure of CO2 and intramucosal pH were calculated. The cytosolic liver enzyme alpha-glutathione S-transferase and standard liver enzyme markers (alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyltransferase) were also measured. Mean arterial pressure in the SNP group was 50…
De novo expression of nonhepatocellular cytokeratins in Mallory body formation.
1998
Mallory bodies (MBs) are eosinophilic cytoplasmic inclusions observed predominantly in alcoholic liver disease. Although linked to disease activity, their pathogenesis is still unclear. Since intermediate filaments (cytokeratins) are major components of MBs, their cytokeratin polypeptide composition was analysed with monospecific antibodies for cytokeratins 7, 8, 14, 18, 19, and 20 by immunohistology. MBs were identified by light microscopy and ubiquitin immunostaining. All MBs were positive for cytokeratins 8 and 18. A significant percentage of the MBs was strongly positive for cytokeratins 19 and/or 20, which are not detectable in hepatocytes of normal liver and, in the case of cytokerati…
Soluble complement receptor type 1 (sCR1) in chronic liver diseases: serum levels at different stages of liver diseases.
1998
SUMMARYComplement receptor type 1 (CR1) is an integral membrane protein of many haematopoietic cells and plays an important role in the clearance of complement-associated immune complexes, favouring their transport to liver and spleen macrophages. A small amount of soluble CR1 (sCR1) is also found in plasma and might originate directly from release of leucocytes and other circulating cells. In previous studies, an increase in serum sCR1 level has been observed in liver cirrhosis and end-stage renal failure. High levels have also been found in patients with some haematologic malignancies. sCR1 serum levels were measured using a specific double sandwich ELISA assay. The present study demonstr…
Spontaneous and antibody-dependent cellular immune reactions to ethanol-altered hepatoma cells
2008
— Spontaneous cell-mediated cytotoxicity (SCMC), antibody-dependent cellular cytotoxicity (ADCC) and proliferative lymphocyte stimulation in alcoholic liver disease (ALD) were investigated. Peripheral blood lymphocytes (PBL) from eight patients with advanced ALD and nine normal controls were tested against hepatoma cells (PLC/PRF/5) as targets. Target cells were grown in either normal culture medium or medium supplemented with 1 and 5% ethanol, respectively, for 24 to 48 h. Ethanol-exposed hepatoma cells exhibited profound and characteristic morphological alterations. Ethanol preincubation, however, proved to be without effect on immune reactions. Provided that hepatoma cells are an appropr…
Impact of Safety-Related Dose Reductions or Discontinuations on Sustained Virologic Response in HCV-Infected Patients: Results from the GUARD-C Cohor…
2015
Background: Despite the introduction of direct-acting antiviral agents for chronic hepatitis C virus (HCV) infection, peginterferon alfa/ribavirin remains relevant in many resource-constrained settings. The non-randomized GUARD-C cohort investigated baseline predictors of safety-related dose reductions or discontinuations (sr-RD) and their impact on sustained virologic response (SVR) in patients receiving peginterferon alfa/ribavirin in routine practice. Methods: A total of 3181 HCV-mono-infected treatment-naive patients were assigned to 24 or 48 weeks of peginterferon alfa/ribavirin by their physician. Patients were categorized by time-to-first sr-RD (Week 4/12). Detailed analyses of the i…
