Hepatitis C virus infection as a risk factor for hepatocellular carcinoma in patients with cirrhosis. A case-control study.
1992
Objective To determine whether chronic hepatitis C virus (HCV) infection is an independent risk factor for hepatocellular carcinoma and whether it increases the cirrhosis-related risk for hepatocellular carcinoma. Design Two pair-matched case-control studies. Setting A referral-based hospital. Patients In study I, 212 patients with hepatocellular carcinoma (197 of whom had known underlying cirrhosis) were compared with controls who had chronic nonhepatic diseases. In study II, the 197 patients with hepatocellular carcinoma and cirrhosis were compared with 197 pair-matched controls who had cirrhosis but not hepatocellular carcinoma. Measurements Levels of antibody to HCV (anti-HCV), hepatiti…
HEPATITIS C AND DIABETES: THE INEVITABLE COINCIDENCE?
2009
Type 2 diabetes (T2D) and HCV infection are common conditions involving, respectively, at least 170 and 130 million people worldwide. However, the distribution of such cases does not overlap in the same age groups in different geographic areas. Following pioneering reports of increased prevalence of T2D in HCV-positive cirrhosis, interest concerning the relationship between HCV and T2D has escalated. HCV is able to induce insulin resistance (IR) directly and the role of specific viral genotypes responsible for such effect is disputed. IR has consistently been found to be closely linked to fibrosis in HCV infection, although also typically associated with T2D in prefibrotic stages. HCV infec…
2011 European Association of the Study of the Liver hepatitis C virus clinical practice guidelines
2012
Hepatitis C virus (HCV) is the leading cause of liver transplantation in Europe and is associated with an increased risk of hepatocellular carcinoma (HCC). Because of the chronic nature of the disease, estimates suggest that the burden on healthcare will increase dramatically for this entity. Clinical care of patients with HCV-related liver disease has advanced considerably in the last two decades, thanks to increasing knowledge about the mechanisms of the disease, development of diagnostic procedures, and advances in therapeutic and preventive approaches. HCV RNA testing, HCV genotyping and staging of liver disease are essential for the diagnosis and the management of HCV therapy. Furtherm…
Detection of hepatitis C virus replication in ovarian metastases of a patient with hepatocellular carcinoma.
1994
Hepatocellular carcinoma is one of the most common human cancers with an annual incidence of about 1,000,000 cases worldwide. Although hepatocellular carcinoma is predominant in hepatitis B virus endemic areas, it has also become a major problem in Europe, Japan and North America in close association with the increasing incidence of hepatitis C virus infection. The pathogenetic role of hepatitis C virus infection in the development of HBsAg-negative hepatocellular carcinoma needs to be clarified. In this paper the case of a 66-year-old HBsAg-negative and anti-HCV positive female who developed hepatocellular carcinoma in a cirrhotic liver is reported. After 1 year of follow up, urgent laparo…
Spike-in SILAC proteomic approach reveals the vitronectin as an early molecular signature of liver fibrosis in hepatitis C infections with hepatic ir…
2014
Hepatitis C virus (HCV)-induced iron overload has been shown to promote liver fibrosis, steatosis, and hepatocellular carcinoma. The zonal-restricted histological distribution of pathological iron deposits has hampered the attempt to perform large-scale in vivo molecular investigations on the comorbidity between iron and HCV. Diagnostic and prognostic markers are not yet available to assess iron overload-induced liver fibrogenesis and progression in HCV infections. Here, by means of Spike-in SILAC proteomic approach, we first unveiled a specific membrane protein expression signature of HCV cell cultures in the presence of iron overload. Computational analysis of proteomic dataset highlighte…
Performance of two HCV RNA assays during protease inhibitor-based triple therapy in patients with advanced liver fibrosis and cirrhosis.
2014
Introduction: On-treatment HCV RNA measurements are crucial for the prediction of a sustained virological response (SVR) and to determine treatment futility during protease inhibitor-based triple therapies. In patients with advanced liver disease an accurate risk/benefit calculation based on reliable HCV RNA results can reduce the number of adverse events. However, the different available HCV RNA assays vary in their diagnostic performance. Aim: To investigate the clinical relevance of concordant and discordant results of two HCV RNA assays during triple therapy with boceprevir and telaprevir in patients with advanced liver fibrosis/cirrhosis. Methods: We collected on-treatment samples of 1…
Executive summary of the 2018 KDIGO Hepatitis C in CKD Guideline: welcoming advances in evaluation and management
2018
Infection with the hepatitis C virus (HCV) has adverse liver, kidney, and cardiovascular consequences in patients with chronic kidney disease (CKD), including those on dialysis therapy and in those with a kidney transplant. Since the publication of the original Kidney Disease: Improving Global Outcomes (KDIGO) HCV Guideline in 2008, major advances in HCV management, particularly with the advent of direct-acting antiviral therapies, have now made the cure of HCV possible in CKD patients. In addition, diagnostic techniques have evolved to enable the noninvasive diagnosis of liver fibrosis. Therefore, the Work Group undertook a comprehensive review and update of the KDIGO HCV in CKD Guideline.…
Genetic association of interleukin-6 polymorphism (-174 G/C) with chronic liver diseases and hepatocellular carcinoma
2012
Interleukin-6 (IL-6) is a pleiotropic cytokine which is expressed in many inflammatory cells in response to different types of stimuli, regulating a number of biological processes. The IL-6 gene is polymorphic in both the 5’ and 3’ flanking regions and more than 150 single nucleotide polymorphisms have been identified so far. Genetic polymorphisms of IL-6 may affect the outcomes of several diseases, where the presence of high levels of circulating IL-6 have been correlated to the stage and/or the progression of the disease itself. The -174 G/C polymorphism is a frequent polymorphism, that is located in the upstream regulatory region of the IL-6 gene and affects IL-6 production. However, the…
Interferon and prevention of hepatocellular carcinoma in viral cirrhosis: an evidence-based approach.
2001
Abstract Background/Aims : To evaluate by meta-analysis of available literature whether interferon (IFN) reduces the incidence of hepatocellular carcinoma (HCC) in patients with hepatitis B virus (HBV) or hepatitis C virus (HCV)-related Child A cirrhosis. Methods : Three randomized controlled trials and 15 nonrandomized controlled trials, including 4614 patients and comparing IFN to no treatment, were selected. Data on the incidence of HCC in IFN treated and untreated patients were extracted from each study. Meta-analysis by the DerSimonian and Laird risk difference (RD) method was used to pool observations. Results : A different incidence of HCC between treated and untreated cirrhotic pati…
Beyond cure

PURPOSE OF REVIEW The aim of this review was to define the implication of hepatitis C virus (HCV) eradication in patients with cirrhosis. RECENT FINDINGS Sustained virologic response (SVR) is associated with a favourable outcome in patients with cirrhosis especially in the presence of regression of cirrhosis but also with extrahepatic outcomes regarding health-related quality of life, risk of diabetes, risk of cardiovascular diseases and control of HIV replication by antiretroviral therapy. In patients with decompensated cirrhosis identifying the point of no return where viral eradication is not followed by clinical improvement is extremely relevant. A strict follow-up is needed in order to…
