COMPUTER ASSISTED IMAGE ANALYSIS OF LIVER COLLAGEN: RELATIONSHIP TO ESOPHAGEAL VARICES, LIVER DECOMPENSATION AND SVR IN PATIENTS WITH COMPENSATED HCV CIRRHOSIS
Real life experiences in HCV management in 2018
Introduction: Hepatitis C virus (HCV) infection is a major cause of chronic liver disease, with approximately 71 million chronically infected individuals worldwide. Treatment of chronic hepatitis C has considerably improved in the last few years thanks to the introduction of direct-acting antivirals able to achieve sustained virological response in more than 95% of patients. Successful anti-HCV treatment can halt liver disease progression and solve the HCV-related extra-hepatic manifestations, eventually reducing liver-related and overall mortality. Areas covered: With the aim to respond to unmet needs in patient’s identification, universal access to antiviral therapy and treatment optimiza…
IL28B polymorphisms influence stage of fibrosis and spontaneous or interferon-induced viral clearance in thalassemia patients with hepatitis C virus infection.
Background. Polymorphisms in the interleukin-28B are important determinants in the spontaneous and drug-induced control of hepatitis C virus infection. Design and Methods. We assessed the association of rs8099917 and rs12979860 polymorphisms with spontaneous viral clearance, severity of liver fibrosis, and response to interferon-monotherapy in 245 Thalassemia Major patients with Hepatitis C Virus infection. Results. Ninety-eight patients (40%) had a spontaneous viral clearance, while 147 patients (60%) developed a chronic infection. Spontaneous viral clearance was more frequent among patients with the T/T genotype of rs8099917 polymorphism (OR 2.130; p=0.008) or C/C genotype of rs12979860 p…
Resistance test guided retreatment of HCV infected patients with a previous failure to a NS5A inhibitor-containing regimen: the Italian Vironet C real life experience
Previous article in issueNext article in issue Introduction: There is a limited documentation about the retreatment of patients failing a recommended NS5A-containing regimen in Italy. Materials & methods: Within the VIRONET-C network, 386 NS5A-failing patients infected with different HCV-genotypes (GT) (GT1a/1b/2a-c/3a-b-g-h/4a-d-n-o-v=93/124/19/112/38) were analyzed. Retreatment of 105 failures was investigated. HCV-resistance-test was performed by Sanger-sequencing. Results: Failures following seven different NS5A-containing regimens were studied: 3D/2D (paritaprevir/ombitasvir ± dasabuvir) ± ribavirin (N = 72/4), daclatasvir/ledipasvir/velpatasvir + sofosbuvir ± ribavirin (N = 105/13…
Point‐of‐care HCV RNA testing in the setting of DAA therapy: HCV‐FiS (HEpatitis C Virus Fingerstick Study)
HCV-RNA assessment during therapy with Direct-Acting Antiviral (DAA) regimens still relies on assays requiring blood collection and transport to a specialised laboratory, which may compromise linkage to care. GeneXpert-HCV Viral Load (GXHVL) (Cepheid) is a plasma-based assay used at point of care (POC) with a sensitivity of ≤10 IU/mL, and, results available within 2 hours. Fifty-nine consecutive HCV-patients ready for DAAs treatment were enrolled. HCV-RNA was simultaneously tested using Roche TaqMan RT-PCR (venous blood sample) and GXHVL (capillary blood collected by fingerstick), at baseline (BL), week 4 (W4) of therapy, end of therapy (EOT) and week 12 of follow-up (W12FU). Both assays de…
Survival of patients with HCV cirrhosis and sustained virologic response is similar to the general population.
Background & Aims: Life expectancy of patients with compensated hepatitis C virus (HCV) cirrhosis achieving sustained virologic response (SVR) is limited by liver events as compared to the general population. Thus, survival benefit of SVR remains to be measured. Methods: The study includes prospective surveillance data from three cohorts of Italian patients with compensated HCV cirrhosis who achieved SVR on an interferon-based (IFN) regimen, compared to simultaneously observed non-SVR, untreated and decompensated patients. Overall survival was calculated from the date of start of IFN to death. The number of deaths expected during the at-risk period was determined by applying age- and se…
Transient elastography (TE) as a tool to evaluate acute liver damage: A prospective, multicentric cohort study
A rs4374383 Single Nucleotide Polymorphisms of MERTK gene is linked to a higher likelihood of hepatocellular carcinoma in patients with HCV cirrhosis
Improved survival of patients with hepatocellular carcinoma and compensated hepatitis C virus-related cirrhosis who attained sustained virological response.
Background Few studies examined the outcome of patients with hepatitis C virus (HCV)-related cirrhosis who developed hepatocellular carcinoma (HCC). The relative weight as determinant of death for cancer vs end-stage liver disease (ESLD) and the benefit of HCV eradication remain undefined. This multicentre, retrospective analysis evaluates overall survival (OS), rate of decompensation and tumour recurrence in compensated HCC patients treated with interferon (IFN) according to HCV status since HCC diagnosis. Methods Two groups of patients with HCV-related cirrhosis and HCC were followed since HCC diagnosis: (i) compensated cirrhotics with prior sustained virological response (SVR) on IFN-bas…
AISF position paper on liver disease and pregnancy.
Abstract The relationship between liver disease and pregnancy is of great clinical impact. Severe liver disease in pregnancy is rare; however, pregnancy-related liver disease is the most frequent cause of liver dysfunction during pregnancy and represents a severe threat to foetal and maternal survival. A rapid differential diagnosis between liver disease related or unrelated to pregnancy is required in women who present with liver dysfunction during pregnancy. This report summarizes the recommendation of an expert panel established by the Italian Association for the Study of the Liver (AISF) on the management of liver disease during pregnancy. The article provides an overview of liver disea…
Fibrosis evaluation by transient elastography in patients with long-term sustained HCV clearance.
Background: Reversibility of advanced fibrosis after HCV-clearance is an important goal of therapy. Objectives: Measuring liver stiffness (LS) by transient elastography (TE) might be helpful in this setting. Patients and Methods: We evaluated 104 patients with biopsy-proven chronic hepatitis C (CHC) and sustained virological response (SVR) after Peg-Interferon (IFN) plus ribavirin since at least 18 months. HCV-eradication was confirmed searching for serum HCV-RNA (TMA® sensitivity > 5-10 IU/ml). Data from literature reported the best LS cut-off values for different stages of liver fibrosis were 7.1 kPa for Metavir stage 2 (F2), 9.5 kPa for F3 and 12.5 for cirrhosis (F4). Results: TE was not…
Different doses of consensus interferon plus ribavirin in patients with hepatitis C virus genotype 1 relapsed after interferon monotherapy: a randomized controlled trial.
AIM: To assess the efficacy of different schedules of consensus interferon (CIFN) plus ribavirin in retreating chronic hepatitis C patients who relapsed after recombinant interferon (rIFN) monotherapy. METHODS: Forty-five patients (34 males and 11 females) with chronic hepatitis due to hepatitis C virus (HCV) genotype 1 who relapsed after a previous course of rIFN monotherapy were randomized to receive 9 μg CIFN three times per week for 52 wk (group A, n = 22) or 18 μg CIFN three times per week for 52 wk (group B, n = 23) in combination with ribavirin 800 to 1200 mg daily for 52 wk (according to body weight). Virological response was evaluated at week 24 (EVR), at the end of treatment (ETR)…
The course of oesophagogastric varices in patients with cirrhosis after DAA-induced HCV clearance
Background and aims: Use of direct acting antivirals (DAAs) has allowed to clear HCV in almost all patients even in the presence of advanced cirrhosis. Although it has been suggested that cirrhotic portal hypertension may regress after SVR, the ultimate effect of HCV clearance on the development and progression of oesophagogastric varices (OV) is still unexplored. We assessed in a prospective cohort of patients with cirrhosis the evolution of endoscopic features of portal hypertension induced by SVR obtained with DAAs. Method: 321 consecutive patients (mean age: 65.1 ± 10.5, males: 58%) with HCV Child-Pugh A cirrhosis treated with DAAs were enrolled between January 2015 and May 2016. All pa…
HepatomiRNoma: The proposal of a new network of targets for diagnosis, prognosis and therapy in hepatocellular carcinoma
Abstract: The diagnosis and treatment of hepatocellular carcinoma (HCC) underwent a huge advancement in the last years. Recently, microRNAs (miRNAs) have been also studied to provide a new tool for early diagnosis of high risk patients, for prognostic classification to identify those patients who benefit cancer treatment and for predictive definition to select the right targeted drug. In this review we revised all the available data obtained to explore the role of miRNAs in HCC. This analysis led to identification of miRNAs which could gain a diagnostic, prognostic or predictive role. The results of studies on miRNAs involved in HCC are initial and far from providing scientific evidences to…
Comparison of cystatin C and creatinine-based glomerular filtration rate formulas with 51Cr-EDTA clearance in patients with cirrhosis
Renal function is an important predictor of survival in cirrhosis and liver transplantation. GFR estimates using serum cystatin C (CysC) are proposed as better predictors of renal function than ones on the basis of serum creatinine (Cr). Our aims were: (1) evaluate correlations between serum CysC and different methods of creatinine measurements; (2) compare CysC and Cr GFR formulas with (51)Cr-EDTA; and (3) evaluate liver-related parameters potentially influencing GFR.254 blood samples in 65 patients with cirrhosis correlating CysC with four Cr methods were used; another 74 patients comparing (51)Cr-EDTA GFR to Modification of Diet in Renal Disease and Larsson and Hoek formulas for CysC wer…
Metabolic comorbidities and male sex influence steatosis in chronic hepatitis C after viral eradication by direct-acting antiviral therapy (DAAs): Evaluation by the controlled attenuation parameter (CAP).
Background: Chronic hepatitis C (CHC) is associated with hepatic steatosis, related to both a direct viral action and metabolic features. Vice-versa data on hepatic steatosis after viral eradication by direct-acting antiviral agents (DAA) are undefined although the presence of metabolic alterations could strongly influence the occurrence of steatosis as in NAFLD. The controlled attenuation parameter (CAP) (FibroscanⓇ) allows the qualitative and quantitative evaluation of fatty liver. Aim: to evaluate in patients with CHC whether hepatic steatosis diagnosed by CAP modifies after DAAs-induced sustained virologic response (SVR). Methods: Data were collected the day of DAAs therapy starting and…
The impact of sustained virological response on clinical outcomes in compensated HCV cirrhosis: a prospective cohort study
HCV CLEARANCE AFTER PEG IFN PLUS RBV IMPROVES THE COURSE OF HCV CIRRHOSIS REGARDLESS OF PORTAL HYPERTENSION
Hepatitis C virus eradication by direct antiviral agents abates oxidative stress in patients with advanced liver fibrosis
Background and aims: HCV eradication improves non-hepatic outcomes such as cardiovascular diseases, although without clearly defined mechanisms. In this study we aimed to assess whether improvement of carotid atherosclerosis may be linked to a reduction in systemic oxidative stress after viral clearance. Methods: We studied a retrospective cohort of 105 patients (age 62.4 ± 11.2 years; 62 men) with F3/F4 fibrosis, characterized by carotid ultrasonography at baseline and at sustained virologic response (SVR) follow-up. Levels of 8-iso-prostaglandin F2α (F2-isoprostanes) and other oxidative stress markers were measured on frozen sera. Association between change (denoted as Δ) in oxidative str…
Safety and efficacy of ombitasvir/paritaprevir/ritonavir/dasabuvir plus ribavirin in patients over 65 years with HCV genotype 1 cirrhosis
Purpose: To analyse safety and efficacy of treatment based on ombitasvir/paritaprevir/ritonavir/dasabuvir plus ribavirin in the sub-group of GT1 patients older than 65 years. Methods: We collected data extracted from the ABACUS compassionate-use nationwide Italian programme, in patients with cirrhosis due to hepatitis C virus (HCV) Genotype-1 (GT1) or 4 and at high risk of decompensation. GT1-HCV-infected patients received once-daily ombitasvir/paritaprevir, with the pharmacokinetic enhancer ritonavir (25/150/100 mg) and twice-daily dasabuvir (250 mg) plus Ribavirin (RBV) (OBV/PTV/r + DSV + RBV) for 12 (GT1b) or 24 (GT1a) weeks. Endpoints were to evaluate safety and efficacy, the latter def…
Clinical course and outcomes of drug-induced liver injury: Nimesulide as the first implicated medication
Abstract Background and aims Drug-induced liver injury (DILI) is the most common cause of death from acute liver failure, and accounts for approximately 13% of cases of acute liver failure in the United States. The clinical presentation of DILI covers a wide spectrum, from asymptomatic liver test abnormalities to symptomatic acute liver disease, prolonged jaundice and disability, or overt acute or subacute liver failure. The aim of our study was to evaluate the number of DILI cases admitted to our Unit and to identify the drugs responsible. Thus, we reviewed all clinical records of patients with DILI admitted to our Unit from 1996 to 2006. Patients and methods A database was constructed, re…
Liver collagen proportionate area predicts decompensation in patients with recurrent hepatitis C virus cirrhosis after liver transplantation
Background and Aims: Current histological scoring systems do not subclassify cirrhosis. Computer-assisted digital image analysis (DIA) of Sirius Red-stained sections measures fibrosis morphologically producing a fibrosis ratio (collagen proportionate area [CPA]). CPA could have prognostic value within a disease stage, such as cirrhosis. The aim of the present study was to evaluate CPA in patients with recurrent hepatitis C virus (HCV) allograft cirrhosis and assess its relationship with hepatic venous pressure gradient (HVPG). Methods: In 121 consecutively-transplanted HCV patients with HVPG, measured contemporaneously with transjugular liver biopsies, 65 had Ishak stage 5 or 6 disease (4…
HBV reactivation in patients with HCV/HBV cirrhosis on treatment with direct-acting antivirals
Anecdotal reports suggest that patients with chronic hepatitis C virus (HCV) hepatitis and overt or occult hepatitis B virus (HBV) coinfection may reactivate HBV when HCV is suppressed or cleared by direct-acting antivirals (DAAs). We assessed the prevalence of overt or previous HBV coinfection and the risk of HBV reactivation in patients with HCV cirrhosis treated with DAAs. This was a retrospective cohort of 104 consecutive patients with HCV cirrhosis treated with DAAs. Serum HCV-RNA and HBV-DNA were tested at weeks 4, 8 and 12 of DAAs therapy and at week 12 of follow-up. At the start of DAAs, eight patients (7.7%) were HBsAg positive/HBeAg negative with undetectable HBV-DNA and low level…
Implication of Normal Liver Enzymes in Liver Disease
Summary. Chronic liver disease is usually asymptomatic until its late stages and also significant hepatic necroinflammation and fibrosis may be present in persistently normal ALT levels HBV, HCV carriers or similarly, in patients with nonalcoholic fatty liver disease. Given the large number of persons in the general population which may harbor a clinically significant liver disease behind the screen of normal alanine aminotransferase, more attention should be devoted to future research for alternative noninvasive markers of liver damage.
RESIST-HCV Criteria to Monitor Progression of Low-Risk Esophageal Varices in Patients With Compensated Cirrhosis After HCV Eradication: The SIMPLE Study: SIMPLE: Scoring Index to Monitor Progression of Low-risk Esophageal varices.
Noninvasive criteria to predict the progression of low-risk esophageal varices (EV) in patients with compensated hepatitis C virus (HCV) cirrhosis after sustained virological response (SVR) by direct-acting antivirals (DAAs) are lacking. Our aim was to assess the diagnostic performance of Rete Sicilia Selezione Terapia-HCV (RESIST-HCV) criteria for EV progression compared with elastography-based criteria (Baveno VI, Expanded Baveno VI, and Baveno VII-HCV criteria).All consecutive patients observed at 3 referral centers with compensated HCV cirrhosis with or without F1 EV who achieved sustained virological response by DAAs were classified at last esophagogastroduodenoscopy (EGDS) as RESIST-H…
Pegylated-interferon and ribavirin in liver transplant candidates and recipients with HCV cirrhosis: systematic review and meta-analysis of prospective controlled studies.
SUMMARY Pegylated interferon with ribavirin (Peg/R) is the most effective therapy for chronic hepatitis C virus (HCV) but its utility and effectiveness after liver transplantation has been difficult to assess. We evaluated efficacy, tolerability, and safety of Peg/R in liver transplant candidates and recipients with HCV cirrhosis. We searched medical databases and conference proceedings between January 1999 and January 2008 selecting randomized and nonrandomized studies. Primary end points meta-analytically were: (1) sustained viral response (SVR) and (2) histological response. Secondary end points were: (1) treatment discontinuation, (2) mortality, and (3) rejection episodes. Pegylated int…
Disease outcomes after DAA-induced SVR: Data from the resist-HCV cohort
Background and aims: Large scale, real life data on the long term course of liver disease after HCV clearance obtained with DAAs are still scanty, and the separate effects on hepatic and non-hepatic causes of death still unclear. Method: We evaluated 4147 patients (mean age: 65.7 ± 11.5 years, 57.6% males) included in the prospective RESIST-HCV cohort who started DAAs treatment in 22 centres between March 2015 and April 2017. All patients were follow after SVR to register liver-related and unrelated outcomes. The primary endpoint was the evaluation of survival since starting DAAs. Cox regression analysis was used to assess the predictors of liver-related and unrelated death. Results: Patien…
Increased expression of markers of early atherosclerosis in patients with inflammatory bowel disease.
Recent studies documented an increased cardiovascular risk in patients with inflammatory bowel disease (IBD). Our study aimed at investigating the prevalence of intima-media thickness (IMT) of the carotid arteries and the arterial stiffness indices as markers of early atherosclerosis in young IBD patients.We recruited 68 consecutive IBD patients, and 38 matched healthy controls less than 45years old (median age 31.6±8.1years). Clinical and demographic features, cardiovascular risk factors, history of cardiovascular events, concomitant therapies were registered on a dedicate database. Carotid IMT was evaluated by using high resolution B-mode ultrasonography. Arterial stiffness was assessed b…
150 LIVER RELATED EVENTS AND SURVIVAL IN PATIENTS WITH COMPENSATED HCV CIRRHOSIS: THE ROLE OF SUSTAINED VIROLOGICAL RESPONSE TO PEG-IFN BASED THERAPY AND PORTAL HYPERTENSION
TACE versus TAE as therapy for hepatocellular carcinoma
Transarterial chemoembolization (TACE) improves survival in cirrhotic patients with hepatocellular carcinoma (HCC). The optimal schedule, best anticancer agent and best technique are still unclear. TACE may not be better than transarterial embolization (TAE). HCC is very chemoresistant, thus embolization may be more important than chemotherapy. Lipiodol cannot be considered as an embolic agent and there are no data to show that it can release chemotherapeutic agents slowly. It can mask residual vascularity on CT imaging and its use is not recommended. Both TACE and TAE result in hypoxia, which stimulates angiogenesis, promoting tumor growth; thus combination of TACE with antiangiogenic agen…
Extrahepatic Manifestations of Chronic HCV
A number of extrahepatic manifestations have been reported in patients infected with HCV. The most prominent of theme are MC vasculitis, lymphoproliferative malignancies, renal disease, polyarthritis, thyroid and glucose disorders. Although these conditions might have a substantial impact on morbidity, patient management, and prognosis, for most of them the exact mechanisms underlying their development require further elucidation.
High efficacy of direct-acting anti-viral agents in hepatitis C virus-infected cirrhotic patients with successfully treated hepatocellular carcinoma
Background: The efficacy of direct-acting anti-viral (DAA) therapy in patients with a history of hepatocellular carcinoma (HCC) is unknown. Aim: We prospectively evaluated whether previously treated HCC affects DAA efficacy in a large real-life cohort of cirrhotic patients. Methods: From January to December 2015 all consecutive HCV mono-infected patients with cirrhosis and/or history of HCC attending 10 Italian tertiary liver centres were enrolled. Baseline characteristics and response to therapy were recorded. 1927 patients were enrolled (mean age: 62.1 10.9 years; 1.205 males). Genotype 1 was the most frequent (67.9%) followed by genotypes 3 (12.4%), 2 (11.2%) and 4 (8.6%). 88.4% and 10.9…
HBV recurrence after HCV clearance on DAAs: Sometimes they come back
Liver stiffness measurement by transient elastography predicts early recovery from acute hepatitis
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…
Insulin resistance is a major determinant of liver stiffness in nondiabetic patients with HCV genotype 1 chronic hepatitis.
BACKGROUND: In patients with chronic hepatitis C (CHC), liver stiffness measurement (LSM) by transient elastography (TE), is closely related to the stage of fibrosis, but may be affected by necroinflammation. Other factors, such as insulin resistance (IR), might influence the performance of LSM. AIMS: To evaluate in a cohort of nondiabetic patients with genotype 1 CHC, whether IR and other anthropometric, biochemical, metabolic and histological factors contribute to LSM and to identify the best cut-off values of LSM for predicting different stages of fibrosis. METHODS: Nondiabetic patients with genotype 1 CHC (n = 156) were evaluated by liver biopsy (Metavir score), anthropometric, biochemi…
Accuracy of Transient Elastography in Assessing Fibrosis at Diagnosis in Naïve Patients With Primary Biliary Cholangitis: A Dual Cut-Off Approach
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…
Computer-assisted image analysis of liver collagen: relationship to Ishak scoring and hepatic venous pressure gradient.
Histopathological scoring of disease stage uses descriptive categories without measuring the amount of fibrosis. Collagen, the major component of fibrous tissue, can be quantified by computer-assisted digital image analysis (DIA) using histological sections. We determined relationships between DIA, Ishak stage, and hepatic venous pressure gradient (HVPG) reflecting severity of fibrosis. One hundred fifteen patients with hepatitis C virus (HCV) who had undergone transplantation had 250 consecutive transjugular liver biopsies combined with HVPG (median length, 22 mm; median total portal tracts, 12), evaluated using the Ishak system and stained with Sirus red for DIA. Liver collagen was expres…
Aminopyrine breath test predicts liver-related events and death in HCV-related cirrhosis on SVR after DAA therapy
Background & Aims: In patients with hepatitis C virus (HCV)-related advanced cirrhosis, the effects of sustained virological response (SVR) by direct antiviral agents (DAAs) on decompensation and liver deaths are less clearcut, since up to 30% of patients do not improve, and no predictors of outcome have been identified. We used 13C-aminopyrine breath test (ABT) to assess whether its changes can predict liver-related outcomes after DAA treatment in patients with HCV cirrhosis. Methods: Fifty consecutive patients with HCV cirrhosis were enrolled. Patients were included if they had Child A cirrhosis at risk for decompensation – defined as Child A6 (N = 22, 44%) or previous decompensation …
Coagulation and fibrosis in chronic liver disease.
In the hepatic tissue repair mechanism, hepatic stellate cells (HSCs) are recruited at the site of injury and their changes reflect paracrine stimulation by all neighbouring cell types, including sinusoidal endothelial cells, Kupffer cells, hepatocytes, platelets and leucocytes. Thrombin converts circulating fibrinogen to fibrin, promotes platelet aggregation, is a potent activator of endothelial cells, acts as a chemoattractant for inflammatory cells and is a mitogen and chemoattractant for fibroblasts and vascular smooth muscle cells. Most of the cellular effects elicited by thrombin are mediated via a family of widely expressed G-protein-coupled receptors termed protease activated recept…

Noninvasive assessment of liver fibrosis in thalassaemia major patients by transient elastography (TE) - lack of interference by iron deposition.
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-beta-thalassaemics. Liver stiffness increased proportionally to liver fibrosis staging (r = 0.70; P > 0.001) independently of liver iron concentration (r = 0.01; P = 0.932). The area under the receiver-operating characteristic curve for prediction of cirrhosis was 0.997 (95% confidence interval [CI]: 0.925-1.000) with cut-off of 13 kPa with 100% sensitivity (95% CI: 69.0-100.0) and 95% specificity (95% CI: 84.2-99.3). Transient elastography is a reliable non-invasive too…
Fecal Calprotectin in Clinical Practice
Background: Surrogate markers of colorectal inflammation are increasingly being recognized as important in differentiating organic from functional intestinal disorders. Fecal calprotectin (FC) can be easily measured in the stool, being released by leukocytes in inflammatory conditions. Aim: We evaluated FC as an index of inflammation in consecutive outpatients referred for colonoscopy for chronic, nonbloody diarrhea. Methods: Stool specimens of 346 outpatients with chronic, nonbloody diarrhea, referred for colonoscopy, were measured for FC levels. The proportion of patients correctly diagnosed with the test and the relationship with endoscopic and histologic findings were measured. Results:…
Is Transient Elastography Needed for Noninvasive Assessment of High-Risk Varices? The REAL Experience
INTRODUCTION: The Baveno VI consensus guidelines and an expanded algorithm suggest that transient elastography (TE) and platelet (PLT) count can be used to identify patients with cirrhosis who can avoid esophagogastroduodenoscopy (EGD). The primary aims of this study were to assess the ability of a simple algorithm, which uses only laboratory parameters, to predict medium/large esophageal varices (EV) in patients with hepatitis C virus (HCV) and cirrhosis from the Rete Sicilia Selezione Terapia-HCV (RESIST-HCV) cohort and to compare the performance of the algorithm with Baveno VI and Expanded Baveno VI criteria. The secondary aim was to assess the role of TE in ruling out large EV. METHODS:…
Mortality after transjugular intrahepatic portosystemic shunt in older adult patients with cirrhosis: A validated prediction model
Background and Aims Implantation of a transjugular intrahepatic portosystemic shunt (TIPS) improves survival in patients with cirrhosis with refractory ascites and portal hypertensive bleeding. However, the indication for TIPS in older adult patients (greater than or equal to 70 years) is debated, and a specific prediction model developed in this particular setting is lacking. The aim of this study was to develop and validate a multivariable model for an accurate prediction of mortality in older adults. Approach and Results We prospectively enrolled 411 consecutive patients observed at four referral centers with de novo TIPS implantation for refractory ascites or secondary prophylaxis of va…
Daclatasvir-based regimens in HCV cirrhosis: experience from the Italian early access program
AbstractWe reported the efficacy and safety data for daclatasvir (DCV)-based all-oral antiviral therapy in patients treated in the Italian compassionate-use program. 275 patients were included (202 male-73.5%, mean age: 57.4 years, 62 HIV-coinfected, 94 with recurrence of hepatitis C post-OLT). Forty-nine patients (17.8%) had Child-Pugh B, Genotype(G) distribution was: G1a:72 patients (26.2%), G1b:137 (49.8%); G3:40 (14.5%) and G4:26 (9.5%). Patients received DCV with sofosbuvir(SOF) (n = 221, 129 with ribavirin(RBV) or with simeprevir (SMV) or asunaprevir (ASU) (n = 54, 19 with RBV) for up to 24 weeks. Logistic regression was used to identify baseline characteristics associated with sustai…
P114 A screening tool for the early diagnosis of extraintestinal manifestations in inflammatory bowel disease: the EMAIL questionnaire
Abstract Background Data on prevalence of extraintestinal manifestations (EIMs) in inflammatory bowel disease (IBD) range from 6% up to 47%. Recently, several red flags and questionnaires have been proposed for early diagnosis of articular manifestations. Our aim was to analyse the prevalence of EIMs in a single-centre prospective cohort, using a comprehensive questionnaire developed by our group to detect all EIMs (EMAIL questionnaire). Methods Patients with IBD attending our Clinic from November 2017 to January 2019 were interviewed using a two-part questionnaire, the first part for clinical-demographic data and the second part for EIMs. Patients positive to screening were referred for mu…
Noninvasive assessment of liver fibrosis in thalassaemia major patients by transient elastography (TE) - lack of interference by iron deposition.
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).

Effectiveness of beta-blocker in primary prevention of variceal bleeding in patients with cirrhosis: A prospective evaluation by hepatic venous pressure gradient measurement
Profiling the risk of hepatocellular carcinoma after long-term HCV eradication in patients with liver cirrhosis in the PITER cohort
Background and aims: Severe liver disease markers assessed before HCV eradication are acknowledged to usually improve after the SVR. We prospectively evaluated, in the PITER cohort, the long-term HCC risk profile based on predictors monitored after HCV eradication by direct-acting antivirals in patients with cirrhosis. Methods: HCC occurrence was evaluated by Kaplan-Meier analysis. Cox regression analysis identified the post-treatment variables associated with de-novo HCC; their predictive power was presented in a nomogram. Results: After the end of therapy (median follow-up:28.47 months), among 2064 SVR patients, 119 (5.8%) developed de-novo HCC. The HCC incidence was 1.90%, 4.21%, 6.47% a…

Background & Aims There are limited data on patients with chronic HCV infection in whom combination voxilaprevir (VOX), velpatasvir (VEL), sofosbuvir (SOF) retreatment fails. Thus, we aimed to assess treatment failure and rescue treatment options in these patients. Methods Samples from 40 patients with HCV genotypes (GT) 1-4 in whom VOX/VEL/SOF retreatment failed were collected within the European Resistance Study Group. Population-based resistance analyses were conducted and clinical parameters and retreatment efficacies were evaluated retrospectively in 22 patients. Results Most VOX/VEL/SOF failure patients were infected with HCV GT3a (n = 18, 45%) or GT1a (n = 11, 28%) and had cirrhosis …
Regression of fibrosis after HBV antiviral therapy. Is cirrhosis reversible?
Long-lasting HBV-DNA suppression is considered to be the best surrogate end-point of antiviral therapy in patients with hepatitis B virus (HBV) related chronic hepatitis or cirrhosis, and it is a prerequisite to prevent liver-related complications and improve survival. Treatment with oral antiviral drugs in patients with HBV cirrhosis is effective in restoring liver function and improving survival even in those with decompensated cirrhosis. These agents are generally well-tolerated for long-term treatment, and several evidences have demonstrated that they are able to reverse liver fibrosis and prevent the occurrence of HCC.
Enhanced thrombin generation in patients with cirrhosis-induced coagulopathy.
Summary. Background: Prothrombin time (PT) and the international normalized ratio (INR) are still routinely measured in patients with liver cirrhosis to ‘assess’ their bleeding risk despite the lack of correlation with the two. Thrombin generation (TG) assays are global assays of coagulation that are showing promise in assessing bleeding and thrombosis risks. Aim: To study the relationship between the INR and TG profiles in cirrhosis-induced coagulopathy. Methods: Seventy-three patients with cirrhosis were studied. All TG parameters were compared with those from a normal control group. Contact activation was prevented using corn trypsin inhibitor. TG was also assayed in the presence of Prot…
P293 Loss of response after first-line biologic therapy in patients with inflammatory bowel disease: practical approach and management
Abstract Background Anti-tumour necrosis factors (anti-TNFs) have greatly improved therapeutic strategies for the treatment of inflammatory bowel diseases (IBDs). However, a significant number of patients do not respond or lose response over time (LOR). The aim of this retrospective prospective study was to evaluate patients (patients) treated with anti-TNFs as first-line treatment, with subsequent LOR, defined as recurrence of disease activity during maintenance therapy. We determine the prevalence of LOR and its management. Methods Three-hundred forty patients with IBDs were included: 65% had Crohn’s disease and 35% ulcerative colitis. Mean age at diagnosis was 31,5 years and medium time …
Peg-interferon alone or combined with ribavirin in HCV cirrhosis with portal hypertension:a randomized controlled trial
Abstract BACKGROUND/AIMS: Risks and benefits of antiviral therapy in HCV cirrhosis with portal hypertension are poorly known. METHODS: We performed a randomized controlled trial in 102 HCV patients with compensated cirrhosis and portal hypertension: 51 received 1 microg/kg/week of Pegylated-interferon alpha-2b and 51 Pegylated-interferon plus 800 mg/day of ribavirin up to 52 weeks. RESULTS: By intention-to-treat analysis, five patients on monotherapy and eleven on combination therapy achieved a sustained virological response (9.8% vs. 21.6%, p=0.06). The response was more frequent for genotypes 2 or 3 than genotype 1 (66.6% vs. 11.3%, p=0.001). Genotype 1, who had low viral load at start of…
Corrigendum to ‘Baveno VII – Renewing consensus in portal hypertension’ [J Hepatol (2022) 959-974]
Comparison of transient elastography and acoustic radiation force impulse for non-invasive staging of liver fibrosis in patients with chronic hepatitis C .
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…
Immunological alterations in hepatitis C virus infection
A higher prevalence of immunological processes has recently been reported in patients with hepatitis C virus (HCV) infection, focusing the attention of physicians and researchers on the close association between HCV and immune disorders. HCV lymphotropism represents the most important step in the pathogenesis of virus-related immunological diseases and experimental, virologic, and clinical evidence has demonstrated a trigger role for HCV both in systemic autoimmune diseases, such as rheumatoid arthritis, Sjogren syndrome, hemolytic anemia and severe thrombocytopenia, and in organ-specific autoimmune diseases, such as autoimmune hepatitis, thyroid disorders and diabetes. This review will out…
Non-invasive prediction of esophageal varices by stiffness and platelet in non-alcoholic fatty liver disease cirrhosis.
Background & Aims: Baveno VI and expanded Baveno VI criteria can avoid the need for esophagogastroduodenoscopy (EGD) to screen for varices needing treatment (VNT) in a substantial proportion of compensated patients with viral and/or alcoholic cirrhosis. This multicenter, cross-sectional study aims to validate these criteria in patients with compensated cirrhosis due to non-alcoholic fatty liver disease (NAFLD), accounting for possible differences in liver stiffness measurement (LSM) values between M and XL probes. Methods: We assessed 790 patients with NAFLD-related compensated cirrhosis who had EGD within six months of a reliable LSM, measured by FibroScan® using M and/or XL probe. Baveno …
An evaluation of transient elastography in the discrimination of HBeAg-negative disease from inactive hepatitis B carriers
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 ± …
Is global elimination of HCV realistic?
The elimination of hepatitis C virus (HCV) has been made possible through the availability of new antiviral drugs which may now be administered to all patients with HCV infection, even those with decompensated cirrhosis. The goal of the World Health Organization (WHO) is to reduce the incidence of chronic hepatitis infection from the current 6-10 million to 0.9 million cases of chronic infections by 2030, and annual deaths from 1.4 million to fewer than 0.5 million. Achieving these targets will require full implementation of epidemiological knowledge of HCV infection, screening and testing practices and strategies to link HCV patients to care. This review will focus on the current state of …
Modified spleen stiffness measurement by transient elastography is associated with presence of large oesophageal varices in patients with compensated hepatitis C virus cirrhosis
To evaluate the accuracy of liver transient elastography (TE), spleen TE and other noninvasive tests (AAR, APRI score, platelet count, platelet/spleen ratio) in predicting the presence and the size of oesophageal varices in compensated hepatitis C virus (HCV) cirrhosis, we studied 112 consecutive patients with compensated HCV cirrhosis who underwent biochemical tests, gastrointestinal endoscopy, liver TE and spleen TE by Fibroscan(®) (Echosens, Paris, France) using a modified software version with a range between 1.5 and 150 kPa. Spleen TE was not reliable in 16 patients (14.3%). Among the 96 patients with a valid measurement (69.8% men, mean age: 63.2 ± 9.5 years), 43.7% had no oesophageal…
Fibrosis in chronic viral hepatitis
In the last years, several studies have been performed with the aim to evaluate the real impact of antiviral treatments on fibrosis progression in patients with chronic viral hepatitis. The main goal of therapy in patients with chronic hepatitis B is viral suppression. This outcome leads to an important improvement in both hepatic inflammation and fibrosis and reduces the HCC occurrence. An histological improvement has been largely demonstrated in patient treated with oral nucleoside and nucleotide analogs achieving the rate of 72% with entecavir and tenofovir. Similarly, in patients with chronic hepatitis C, sustained virologic response to interferon therapy is associated with regression o…
Current epidemiology of HCV in Sicily: the RESIST-HCV model
Background: Real-world data to guide hepatitis C virus (HCV)- related public health initiatives and linkage to care of patients are lacking in our region. Aims: To describe the epidemiological features of a large cohort of patients with chronic HCV infection from Sicily included in a regional network aimed at DAA treatment (RESIST-HCV). Methods: Demographic and clinical data were recorded on a web-based platform before starting treatment with DAAs. Gender, year of birth, HCV genotype, co-infections, stages of liver disease and co-morbidities were analyzed. Chi-square with Yates correc- tion was appliedto assess the differences between cohorts. Results: Overall, 15,270 patients were register…
Frequent NS5A and multiclass resistance in almost all HCV genotypes at DAA failures: What are the chances for second-line regimens?
Treatment of Hepatitis C virus infection in Italy: A consensus report from an expert panel
Abstract Hepatitis C virus (HCV) infection remains one of the main causes of chronic liver disease worldwide. The advent of direct-acting antivirals (DAAs) has significantly improved the course of patients with chronic HCV infection (CHC), due to the ability of these drugs to achieve high rates of sustained virological response (SVR). These exceedingly high rates of SVR and the excellent safety data have been confirmed in real life practice. Evolving guidelines have been issued by national and international scientific societies in accordance with the progression of clinical knowledge and the availability of new DAAs. These recommendations, however, may not be applied universally because of …
Primary biliary cholangitis (PBC): The patient journey to diagnosis and through the disease
Hepassocin as a treatment for fulminant hepatic failure: will it translate from rats to human?
Acute liver failure (ALF) is defined as the abrupt loss of hepatic cellular function in a patient without pre-existing liver disease, with the subsequent development of coagulopathy, jaundice and encephalopathy. It remains one of the most challenging medical emergencies, due to the multiorgan nature of the disease, the rapid evolution of the clinical condition and the need for multidisciplinary supportive interventions in order to assess the necessity for liver transplantation (LT) correctly.1 Despite different causes of ALF, the mode of cell death typically follows one of two patterns: necrosis or apoptosis; apoptosis is manifest by nuclear and cytoplasmic shrinkage without disturbance of …
Dual therapy with peg-interferon and ribavirin in thalassemia major patients with chronic HCV infection: Is there still an indication?
Background: Iron overload and hepatitis C virus (HCV) infection together can lead to chronic liver damage in thalassemia major (TM) patients. Aims: We investigated viral, genetic, and disease factors influencing sustained virological response (SVR) after peg-interferon and ribavirin therapy in TM patients with HCV infection. Methods: We analyzed 230 TM patients with HCV infection (mean age 36.0 ± 6.3 years; 59.1% genotype 1; 32.2% genotype 2; 3.4% genotype 3; and 5.3% genotype 4; 28.7% carried CC allele of rs12979860 in IL28B locus; 79.6% had chronic hepatitis and 20.4% cirrhosis; 63.5% naive and 36.5% previously treated with interferon alone) treated in 14 Italian centers. Results: By mul…
Mer Tyrosine Kinase (MERTK) modulates liver fibrosis progression and hepatocellular carcinoma development.
BackgroundMerTK is a tyrosine kinase receptor that belongs to the TAM (Tyro3/Axl/Mer) receptor family. It is involved in different processes including cellular proliferation/survival, cellular adhesion/migration, and release of the inflammatory/anti-inflammatory cytokines. Although it is reported that MERTK polymorphisms affect the severity of viral and metabolic liver diseases, being able to influence fibrosis progression and hepatocellular carcinoma development, the mechanisms remain unknown. Methods: using a microarray approach, we evaluated the liver expression of genes involved in fibrogenesis and hepatocarcinogenesis in patient with chronic hepatitis C (CHC), stratified for MERTK geno…
Why do I treat my patients with mild hepatitis C?
The major advances achieved in the treatment of HCV by the development of new direct-acting antiviral agents (DAAs) allow treatment of almost the entire spectrum of patients with chornic infection. As a result of the exceedingly high cost of DAAs in many countries, IFN-free DAA regimens are mostly reserved to patients with advanced fibrosis or cirrhosis. Hence, treatment of patients with milder liver disease is often deferred. This could ultimately result in an increased burden of advanced liver disease and in increased long-term costs of management. Moreover, studies performed during the 'interferon era' and the early data on interferon-free regimens show that patients without severe fibro…
Refining the Baveno VI elastography criteria for the definition of compensated advanced chronic liver disease
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…
First-Line Immune Checkpoint Inhibitor-Based Sequential Therapies for Advanced Hepatocellular Carcinoma: Rationale for Future Trials
<b><i>Introduction:</i></b> Atezolizumab (ATEZO) plus bevacizumab (BEVA) represents the new standard of care for the treatment of advanced hepatocellular carcinoma (HCC). However, the choice of the second-line treatment after the failure of immunotherapy-based first-line remains elusive. Taking into account the weaknesses of the available evidence, we developed a simulation model based on available phase III randomized clinical trials (RCTs) to identify optimal risk/benefit sequential strategies. <b><i>Methods:</i></b> A Markov model was built to estimate the overall survival (OS) of sequential first- and second-line systemic treatments. Seque…
Effects of Eradicating Hepatitis C Virus Infection in Patients With Cirrhosis Differ With Stage of Portal Hypertension.
Clearance of hepatitis C virus (HCV) via antiviral treatment changes the course of liver disease. We evaluated the benefit of sustained virologic response (SVR) in patients with HCV and cirrhosis without (stage 1) and with (stage 2) esophageal varices (EV).We performed a prospective cohort study of 444 patients with HCV and compensated cirrhosis (218 with stage 1 and 226 with stage 2 disease) treated with peg-interferon and ribavirin from June 2001 through December 2009 at the University of Palermo, Italy and followed for a median of 7.6 years (range, 1-12.6 years). We used Cox regression analysis to identify variables associated with appearance or progression of EVs, development of hepatoc…
PEG-INTERFERON PLUS RIBAVIRIN IN COMPENSATED HCV CIRRHOSIS WITH PORTAL HYPERTENSION: THE ROLE OF RAPID AND EARLY VIROLOGICAL RESPONSE IN PREDICTING THE SUSTAINED VIROLOGICAL RESPONSE
Baveno VII – Renewing consensus in portal hypertension
To expand on the work of previous meetings, a virtual Baveno VII workshop was organised for October 2021. Among patients with compensated cirrhosis or compensated advanced chronic liver disease (cACLD – defined at the Baveno VI conference), the presence or absence of clinically significant portal hypertension (CSPH) is associated with differing outcomes, including risk of death, and different diagnostic and therapeutic needs. Accordingly, the Baveno VII workshop was entitled “Personalized Care for Portal Hypertension”. The main fields of discussion were the relevance and indications for measuring the hepatic venous pressure gradient as a gold standard, the use of non-invasive tools for the …
Risk of cirrhosis-related complications in patients with advanced fibrosis following hepatitis C virus eradication
Background & Aims: The risk of hepatocellular carcinoma (HCC) is reduced but not eradicated among patients with hepatitis C virus (HCV)-induced advanced hepatic fibrosis who attained sustained viral response (SVR). We aimed to assess the risk of cirrhosis-related complications in this specific group of patients. Methods: Data from previously reported Western cohort studies including patients with chronic HCV infection and bridging fibrosis or cirrhosis who attained SVR were pooled for survival analyses on the individual patient level. The primary endpoint was HCC and the secondary endpoint was clinical disease progression, defined as liver failure, HCC or death. Results: Included were 1…
Efficacy of 8 weeks elbasvir/grazoprevir regimen for naïve-genotype 1b, HCV infected patients with or without glucose abnormalities: Results of the EGG18 study.
Background and aim: Direct Acting Antivirals(DAAs) achieve the highest rate of sustained viral re- sponse(SVR) in patients with genotype-1b(G1b) Hepatitis C virus(HCV) infection. Reducing treatment du- ration can simplify the management and improve adherence of therapy. Patients and methods: The study evaluates the efficacy of 8 weeks of elbasvir/grazoprevir regimen in 75 treatment-naïve(TN), G1b patients with mild-moderate fibrosis(Liver Stiffness by Fibroscan®< 9.0 kPa).

Twenty-eight patients(37.3%) had an HOMA > …
Residual risk of hepatocellular carcinoma after HCV eradication: more than meets the eye.
ABSTRACT Eradication of HCV in patients with advanced liver fibrosis or cirrhosis reduces, but does not altogether abolish, the risk of development of hepatocellular carcinoma. The reasons underlying this residual risk remain elusive. Even if HCV clearance eliminates its direct and indirect carcinogenic effects, the persistence of cirrhosis and the possible coexistence of metabolic factors (diabetes, obesity and insulin resistance) and of alcohol abuse can promote the development of hepatocellular carcinoma acting as autonomous, nonviral carcinogenic factors. Lessons learned in the IFN era may still assist in predicting the forthcoming scenario, when IFN-free regimens will obtain high rat…
Child-Pugh Class and Not Thrombocytopenia Impacts the Risk of Complications of Endoscopic Band Ligation in Patients with Cirrhosis and High Risk Varices
Background and Aims: Endoscopic band legation (EBL) is an effective method for the prophylaxis of acute variceal bleeding (AVB). This procedure may be associated with several complications, particularly bleeding. Our analysis aimed to evaluate the risk of complications due to EBL in a cohort of patients who underwent EBL for the prophylaxis of variceal bleeding and the eventual presence of risk predictors. Patients and Methods: We retrospectively analysed data from consecutive patients who underwent EBL in a primary prophylaxis regimen. For all patients, simultaneously with EBL, we recorded the Child–Pugh and MELD score, platelet count and US features of portal hypertension. Results: We col…
Performance of two HCV RNA assays during protease inhibitor-based triple therapy in patients with advanced liver fibrosis and cirrhosis.
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…
Error factors for transient elastography in chronic hepatitis C
Prevalence of Single and Multiple Natural NS3, NS5A and NS5B Resistance-Associated Substitutions in Hepatitis C Virus Genotypes 1-4 in Italy
AbstractNatural resistance-associated substitutions (RASs) are reported with highly variable prevalence across different HCV genotypes (GTs). Frequency of natural RASs in a large Italian real-life cohort of patients infected with the 4 main HCV-GTs was investigated. NS3, NS5A and NS5B sequences were analysed in 1445 HCV-infected DAA-naïve patients. Sanger-sequencing was performed by home-made protocols on 464 GT1a, 585 GT1b, 92 GT2c, 199 GT3a, 16 GT4a and 99 GT4d samples. Overall, 20.7% (301/1455) of patients showed natural RASs, and the prevalence of multiclass-resistance was 7.3% (29/372 patients analysed). NS3-RASs were particularly common in GT1a and GT1b (45.2-10.8%, respectively), mai…
High rate of misclassification of fibrosis stage using transient elastography thresholds to prioritize HCV patients for antiviral treatment
Incidence of Hepatocellular Carcinoma in Patients With HCV-Associated Cirrhosis Treated With Direct-Acting Antiviral Agents.
Background & Aims: Studies have produced conflicting results of the incidence of hepatocellular carcinoma (HCC) in patients with hepatitis C virus–associated cirrhosis treated with direct-acting antivirals (DAAs). Data from clinics are needed to accurately assess the occurrence rate of HCC in patients with cirrhosis in the real world. Methods: We collected data from a large prospective study of 2,249 consecutive patients (mean age = 65.4 years, 56.9% male) with hepatitis C virus–associated cirrhosis (90.5% with Child-Pugh class A and 9.5% with Child-Pugh class B) treated with DAAs from March 2015 through July 2016 at 22 academic and community liver centers in Sicily, Italy. HCC occurren…
The risk of hepatocellular carcinoma in HBV cirrhosis is affected by polymorphisms of the MERTK gene
Quantification of fibrosis by collagen proportionate area predicts hepatic decompensation in hepatitis C cirrhosis.
SummaryBackground It is unclear whether the course of cirrhosis and its prognosis are related to the amount of collagen in the liver. Aim To determine whether fibrosis, assessed by collagen proportionate area (CPA) in patients with compensated cirrhosis, is associated with the presence of oesophageal varices, and predict disease decompensation during the follow-up period. Methods We prospectively evaluated 118 consecutive patients with compensated cirrhosis to correlate fibrosis, assessed by CPA in liver biopsies, with the presence of oesophageal varices (OV) and with the rate of liver decompensation (LD) development during a median follow-up of 72 months. Results At baseline 38 (32.2%) pat…
Suboptimal performance of APRI and FIB-4 in ruling out significant fibrosis and confirming cirrhosis in HIV/HCV co-infected and HCV mono-infected patients
Purpose: We aimed to assess the diagnostic reliability of two indirect biomarkers, APRI and FIB-4, for the staging of liver fibrosis using transient elastography (TE) as reference standard, among HIV/HCV co-infected and HCV mono-infected patients. Methods: This is an observational, retrospective study on subjects who had access to the RESIST HCV from October 2013 to December 2016, a regional network encompassing 22 hospitals and academic centers throughout Sicily. Sensitivity, specificity and diagnostic accuracy of indirect biomarkers for liver stiffness measurement (LSM) < 9.5 kPa (significant fibrosis) and LSM ≥ 12.5 kPa (cirrhosis) were determined by receiver operator characteristics …
Digital image analysis of liver collagen predicts clinical outcome of recurrent hepatitis C virus 1 year after liver transplantation.
Clinical outcomes of recurrent hepatitis C virus after liver transplantation are difficult to predict. We evaluated collagen proportionate area (CPA), a quantitative histological index, at 1 year with respect to the first episode of clinical decompensation. Patients with biopsies at 1 year after liver transplantation were evaluated by Ishak stage/grade, and biopsy samples stained with Sirius red for digital image analysis were evaluated for CPA. Cox regression was used to evaluate variables associated with first appearance of clinical decompensation. Receiver operating characteristic (ROC) curves were also used. A total of 135 patients with median follow-up of 76 months were evaluated. At 1…

Results: The overall mortality during ICU st…
2011 European Association of the Study of the Liver hepatitis C virus clinical practice guidelines
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…
Long-term albumin administration in decompensated cirrhosis (ANSWER): an open-label randomised trial
Background Evidence is scarce on the efficacy of long-term human albumin (HA) administration in patients with decompensated cirrhosis. The human Albumin for the treatmeNt of aScites in patients With hEpatic ciRrhosis (ANSWER) study was designed to clarify this issue. Methods We did an investigator-initiated multicentre randomised, parallel, open-label, pragmatic trial in 33 academic and non-academic Italian hospitals. We randomly assigned patients with cirrhosis and uncomplicated ascites who were treated with anti-aldosteronic drugs (≥200 mg/day) and furosemide (≥25 mg/day) to receive either standard medical treatment (SMT) or SMT plus HA (40 g twice weekly for 2 weeks, and then 40 g weekly…
Predictors of hepatocellular carcinoma in HCV cirrhotic patients treated with direct acting antivirals
Background: Despite the dramatic improvement in viral eradication rates that has been reached with direct antiviral agents (DAAs),the real benefit of viral eradication after DAAs on hepatocellular carcinoma (HCC) development is still controversial. Aim: To prospectively assess the risk of HCC occurrence and early recurrence in a large cohort of DAAtreated HCV-cirrhotic patients and to identify potential predictors of HCC development. Methods: We analyzed data prospectively collected from 1927 consecutive HCV-infected cirrhotic patients treated with DAA from January to December 2015 in 10 tertiary liver centers in Italy and followed-up for one year after therapy. 161 patients had a previous …

Impact of hepatitis C virus clearance by direct-acting antiviral treatment on the incidence of major cardiovascular events: A prospective multicentre study
Background and aims: HCV is associated with an increased risk of cardiovascular events (CV). Whether HCV clearance by direct-acting antivirals (DAA) reduces incident CV disease is poorly understood. We investigate whether HCV eradication reduces CV events. Methods: In a prospective multicentre study, 2204 HCV patients (F0–F2:29.5%, F3–F4: 70.5%) were enrolled. Males were 48%, median age was 68 (59–74) years and BMI 25.9 (23.1–28); 24.7% were smokers, 18% had diabetes, 13.2% had cholesterol levels >200 mg/dl and 9.1% took statins, 44% had hypertension. During an overall median follow-up of 28 (24–39) months, incident CV events, such as ischemic heart disease (IHD) and ischemic cerebral st…

The impact of sustained virological response on clinical outcome in compensated HCV cirrhosis: a prospective cohort study
Identification of Naïve Hcv-1 Patients with Chronic Hepatitis who may Benefit from Dual Therapy with Peg-Interferon and Ribavirin.
Background & Aims The pool of HCV genotype 1 patients likely to be cured by peg-interferon and ribavirin remains to be quantified. Methods In 1045 patients treated with peg-interferon and ribavirin, two therapeutic strategies were confronted: the first one evaluated only baseline variables associated with sustained virological response (SVR), and the second one included the rapid virologic response (RVR) in addition to baseline predictors. An 80% SVR rate was the threshold to retain a strategy as clinically relevant. Results Overall, 414 patients (39.6%) attained SVR. In the first strategy, the hierarchy of features independently associated with SVR was IL28B CC genotype (OR 5.082; CI 3.637…
X Chromosome Contribution to the Genetic Architecture of Primary Biliary Cholangitis
Background & aims: Genome-wide association studies in primary biliary cholangitis (PBC) have failed to find X chromosome (chrX) variants associated with the disease. Here, we specifically explore the chrX contribution to PBC, a sexually dimorphic complex autoimmune disease. Methods: We performed a chrX-wide association study, including genotype data from 5 genome-wide association studies (from Italy, United Kingdom, Canada, China, and Japan; 5244 case patients and 11,875 control individuals). Results: Single-marker association analyses found approximately 100 loci displaying P < 5 × 10-4, with the most significant being a signal within the OTUD5 gene (rs3027490; P = 4.80 × 10-6; odds…
Hemostatic balance in patients with liver cirrhosis: Report of a consensus conference.
Abstract Patients with cirrhosis present with hemostatic alterations secondary to reduced availability of pro-coagulant and anti-coagulant factors. The net effect of these changes is a rebalanced hemostatic system. The Italian Association of the Study of the Liver (AISF) and the Italian Society of Internal Medicine (SIMI) promoted a consensus conference on the hemostatic balance in patients with cirrhosis. The consensus process started with the review of the literature by a scientific board of experts and ended with a formal consensus meeting in Rome in December 2014. The statements were graded according to quality of evidence and strength of recommendations, and approved by an independent …
Hepatic benefits of HCV cure
Direct-acting antiviral (DAA)-induced HCV clearance conceivably leads to improved outcomes at all stages of liver disease. However, available data suggest that the maximum measurable benefit is obtained by treating patients before they reach the stage of compensated advanced chronic liver disease (cACLD). Ideally, all patients with chronic hepatitis C should be treated before they develop advanced fibrosis or cirrhosis, since even if sustained virologic response (SVR) reduces the risk of hepatic events (e.g. decompensation and hepatocellular carcinoma [HCC]) and improves survival, further progression of liver disease and adverse outcomes, including hepatic deaths, cannot be entirely avoided…
Clinical features and comorbidity pattern of HCV infected migrants compared to native patients in care in Italy: A real-life evaluation of the PITER cohort
Background: Direct-acting antivirals are highly effective for the treatment of hepatitis C virus (HCV) infection, regardless race/ethnicity. We aimed to evaluate demographic, virological and clinical data of HCV-infected migrants vs. natives consecutively enrolled in the PITER cohort. Methods: Migrants were defined by country of birth and nationality that was different from Italy. Mann-Whitney U test, Chi-squared test and multiple logistic regression were used. Results: Of 10,669 enrolled patients, 301 (2.8%) were migrants: median age 47 vs. 62 years, (p < 0.001), females 56.5% vs. 45.3%, (p < 0.001), HBsAg positivity 3.8% vs. 1.4%, (p < 0.05). Genotype 1b was prevalent in both gro…
Impact of Tips Preliver Transplantation for the Outcome Posttransplantation
The effects of transjugular intrahepatic portocaval shunt (TIPS) on the survival of grafts and patients after liver transplantation (LTx) have only been documented in small series and with only a comparative description with non-TIPS recipients. We evaluated 61 TIPS patients who had a subsequent LTx and compared these with 591 patients transplanted with cirrhosis without TIPS. Pretransplant characteristics were similar between groups. Graft survival at 1, 3 and 5 years post-LTx was 85.2%, 77% and 72.1% (TIPS) and 75.3%, 69.8% and 66.1% (controls). Patient survival at the same points was 91.7%, 85% and 81.7%, respectively (TIPS) and 85.4%, 80.3% and 76.2% (controls). Cox regression showed th…
P228 Cytomegalovirus Infection: is it a cause of flare-up in inflammatory bowel diseases?
Abstract Background The presence of CMV in blood is quite common in patients with severe flares of ulcerative colitis (UC) and Crohn’s disease (CD) and seems to predict an adverse outcome. The impact of antiviral treatment on CMV in this setting (indications and drug options) is an unresolved issue. Our aim was to reassess the CMV role in patients with IBD hospitalised for severe exacerbations, analysing the relationship between CMV positivity, clinical characteristics, antiviral therapy and disease outcomes. Methods We evaluated a homogeneous cohort of 97 consecutive patients with IBD hospitalised from 2012 to 2018. Data regarding age, gender, smoke, familial predisposition, type of IBD, e…
Comparison of Histochemical Stainings in Evaluation of Liver Fibrosis and Correlation with Transient Elastography in Chronic Hepatitis.
Background and Aim. The best staining to evaluate liver fibrosis in liver hepatitis is still a debated topic. This study aimed to compare Masson’s trichrome (MT), Sirius Red (SR), and orcein stainings in evaluating liver fibrosis in chronic HCV hepatitis (CHC) with semiquantitative and quantitative methods (Collagen Proportionate Area (CPA) by Digital Image Analysis (DIA)) and correlate them with transient elastography (TE).Methods. Liver stiffness evaluation of 111 consecutive patients with CHC was performed by TE. Semiquantitative staging by Metavir score system and CPA by DIA were assessed on liver biopsy stained with MT, SR, and orcein.Results. MT, SR, and orcein staining showed concord…

An international genome-wide meta-analysis of primary biliary cholangitis: Novel risk loci and candidate drugs.
[BACKGROUND & AIMS] Primary biliary cholangitis (PBC) is a chronic liver disease in which autoimmune destruction of the small intra-hepatic bile ducts eventually leads to cirrhosis. Many patients have inadequate response to licensed medications, motivating the search for novel therapies. Previous genome-wide association studies (GWAS) and meta-analyses (GWMA) of PBC have identified numerous risk loci for this condition, providing insight into its aetiology. We undertook the largest GWMA of PBC to date, aiming to identify additional risk loci and prioritise candidate genes for in silico drug efficacy screening. [METHODS] We combined new and existing genotype data for 10, 516 cases and 20, 77…

Enhanced thrombin generation in patients with cirrhosis-induced coagulopathy
Digital image analysis of collagen assessment of progression of fibrosis in recurrent HCV after liver transplantation
BACKGROUND & AIMS: Histological assessment of fibrosis progression is currently performed by staging systems which are not continuous quantitative measurements. We aimed at assessing a quantitative measurement of fibrosis collagen proportionate area (CPA), to evaluate fibrosis progression and compare it to Ishak stage progression. METHODS: We studied a consecutive cohort of 155 patients with recurrent HCV hepatitis after liver transplantation (LT), who had liver biopsies at one year and were subsequently evaluated for progression of fibrosis using CPA and Ishak staging, and correlated with clinical decompensation. The upper quartile of distribution of fibrosis rates (difference in CPA or Is…
Improvement of ALT decay kinetics by all-oral HCV treatment: Role of NS5A inhibitors and differences with IFN-based regimens
Background Intracellular HCV-RNA reduction is a proposed mechanism of action of direct-acting antivirals (DAAs), alternative to hepatocytes elimination by pegylated-interferon plus ribavirin (PR). We modeled ALT and HCV-RNA kinetics in cirrhotic patients treated with currently-used all-DAA combinations to evaluate their mode of action and cytotoxicity compared with telaprevir (TVR)+PR. Study design Mathematical modeling of ALT and HCV-RNA kinetics was performed in 111 HCV-1 cirrhotic patients, 81 treated with all-DAA regimens and 30 with TVR+PR. Kinetic-models and Cox-analysis were used to assess determinants of ALT-decay and normalization. Results HCV-RNA kinetics was biphasic, reflecting …
Direct-acting antivirals after successful treatment of early hepatocellular carcinoma improve survival in HCV-cirrhotic patients
Background & Aims: The effectiveness of direct-acting antivirals (DAAs) against hepatitis C virus (HCV), following successful treatment of early hepatocellular carcinoma (HCC), has been studied extensively. However, the benefit in terms of overall survival (OS) remains to be conclusively demonstrated. The aim of this study was to assess the impact of DAAs on OS, HCC recurrence, and hepatic decompensation. Methods: We prospectively enrolled 163 consecutive patients with HCV-related cirrhosis and a first diagnosis of early Barcelona Clinic Liver Cancer stage 0/A HCC, who had achieved a complete radiologic response after curative resection or ablation and were subsequently treated with DAA…
Rs4374383 single nucleotide polymorphism of MERTK gene influences the development of hepatocellular carcinoma (HCC) in patients with HCV cirrhosis
The relationship between transient elastography and histological collagen proportionate area for assessing fibrosis in chronic viral hepatitis
Collagen proportionate area (CPA) has a better correlation with hepatic venous pressure gradient (HVPG) than with Ishak stage. Liver stiffness measurement (LSM) is proposed as non invasive marker of portal hypertension/disease progression. Our aim was to compare LSM and CPA with Ishak staging in chronic viral hepatitis, and HVPG in HCV hepatitis after transplantation. One hundred and sixty-nine consecutive patients with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections pre/post liver transplantation (LT), had a liver biopsy combined with LSM (transient elastography), CPA (biopsies stained with Sirius Red and evaluated by digital image analysis and expressed as CPA) and H…

Impact of virus eradication in patients with compensated hepatitis C virus-related cirrhosis: competing risks and multistate model
BACKGROUND & AIMS No published study to date has provided a careful analysis of the effects of a sustained viral response (SVR) on the outcomes of patients with compensated hepatitis C virus (HCV)-related cirrhosis in relation to the degree of portal hypertension. Therefore, we estimated the impact of achieving SVR on disease progression, hepatocellular carcinoma (HCC) development and mortality in a large cohort of HCV patients with cirrhosis with or without oesophageal varices (OVs) at the start of antiviral therapy. METHODS A total of 535 Caucasian patients were prospectively recruited to this study. All patients had a clinical or histological diagnosis of compensated HCV-related cirrhosi…
Liver and cardiovascular mortality after hepatitis C virus eradication by DAA: Data from RESIST-HCV cohort
Real-world evidence on the course of Hepatitis C Virus (HCV) chronic liver disease after Sustained Virologic Response (SVR) obtained with direct-acting antiviral drugs (DAAs) are still limited, and the effects on mortality remain unclear. We evaluated the post-treatment survival of 4307 patients in the RESIST-HCV cohort (mean age 66.3 ± 11.6 years, 56.9% males, 24.7% chronic hepatitis, 66.9% Child-Pugh A cirrhosis and 8.4% Child-Pugh B cirrhosis) treated with DAAs between March 2015 and December 2016 and followed for a median of 73 weeks (range 16–152). Proportional cause-specific hazard regression for competing risks was used to evaluate the survival and to assess the predictors of liver a…
Who is more likely to respond to dual treatment with pegylated-interferon and ribavirin for chronic hepatitis C? A gender-oriented analysis.
Summary We assessed, in real-life practice, viral, demographic, genetic and metabolic factors influencing the sustained virologic response (SVR), with a gender-oriented analysis, in patients with chronic hepatitis C virus (HCV) treated with pegylated interferon and ribavirin. Six hundred and seventy naive patients were treated with dual therapy and evaluated by gender and HCV genotype. Associations between baseline variables and SVR were assessed by multivariate logistic regression analysis. Among 362 genotype 1 patients, SVR was achieved in 158 patients (44%), and SVR was independently associated with age less than 50 years (OR 2.12; 95% CI 1.09–4.30; P = 0.039) and C/C genotype rs12979860…
On-treatment serum albumin level can guide long-term treatment in patients with cirrhosis and uncomplicated ascites
Background & Aims: The ANSWER study reported that long-term albumin administration in patients with cirrhosis and uncomplicated ascites improves survival. During treatment, serum albumin increased within a month and remained stable thereafter. In this post hoc analysis, we aimed to determine whether on-treatment serum albumin levels could guide therapy. Methods: Logistic regression was used to assess the association between baseline serum albumin and mortality, as well as to determine on-treatment factors associated with mortality and to predict the achievement of a given on-treatment serum albumin level. Survival was assessed by Kaplan-Meier estimates and second-order polynomial regres…
Role of IL-28B and inosine triphosphatase polymorphisms in efficacy and safety of Peg-Interferon and ribavirin in chronic hepatitis C compensated cirrhosis with and without oesophageal varices
Summary. Genetic factors can influence the outcome of antiviral therapy in chronic hepatitis C (HCV). We evaluated the role of interleukin-28B single nucleotide polymorphisms (SNPs) and inosine triphosphatase (ITPA) gene variants in HCV cirrhosis treated with Peg-Interferon and ribavirin. A prospective cohort of 233 patients with compensated cirrhosis received 1–1.5 μg/kg/week of Peg-Interferon alpha-2b plus 1000–1200 mg/day of RBV for 48 weeks. A sustained virologic response (SVR) was achieved in 27% of patients. On multivariate logistic analysis, the absence of oesophageal varices (OR 3.64 CI 95% 1.27–10.44 P = 0.016), infection with genotype 2 or 3 (OR 4.06, CI 95% 1.08–15.26, P = 0.038…
Real-world experience with obeticholic acid in patients with primary biliary cholangitis
Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…
Muscle cramps in cirrhosis: the therapeutic value of quinine. Is it underused?
Muscle cramps are a common and recurring symptom in patients with cirrhosis. Although, the pathophysiology has not been specifically studied in cirrhosis, this is thought to be the same for cramps in general, originating in the motorneurone, with high frequency firing of motor unit action potentials. However precise pathophysiological mechanisms are not known. Risk factors in cirrhosis have been little studied. Neither aetiology, nor pre-ascitic or ascitic stage, nor electrolyte disturbances, nor use of diuretic therapy has been found to have a statistical association with cramps in patients with cirrhosis. Effective treatments, from this literature review, are albumin, which however is exp…
Reduced incidence of type 2 diabetes in patients with chronic hepatitis C virus infection cleared by direct-acting antiviral therapy: A prospective study
Aim HCV infection increases the risk of type 2 diabetes mellitus (T2DM). However, it remains still unclear whether HCV clearance by direct-acting antivirals (DAA) reduces T2DM. Therefore, the effect of HCV eradication on T2DM incidence was assessed. Methods A prospective multicenter case-control study was performed, which included 2,426 HCV patients, 42% of which with liver fibrosis F0-F2 and 58% F3-F4. Study population consisted of a control group including 1099 untreated patients and 1327 cases treated with DAA. T2DM incidence was assessed during a follow-up median period of 30 [IQR: 28-42] months. Risk factors of T2DM were assessed by Cox regression model (Relative risk (RR), Hazard risk…
Meccanismi immunologici e molecolari del danno epatico da farmaci
I polimorfismi genetici e/o i fattori ambientali, ad esempio l’alcol e/o i farmaci concomitanti, contribuiscono alla suscettibilità individuale nel determinare il danno epatico da farmaci. L’HLA si è dimostrato essere uno dei più importanti predittore di suscettibilità individuale anche per quei farmaci per i quali questa non era stata mai sospettata.

High rate of spontaneous viral clearance in patients with iatrogenic acute hepatitis C
Multiclass HCV resistance to direct-acting antiviral failure in real-life patients advocates for tailored second-line therapies
Background & Aims: Despite the excellent efficacy of direct-acting antivirals (DAA) reported in clinical trials, virological failures can occur, often associated with the development of resistance-associated substitutions (RASs). This study aimed to characterize the presence of clinically relevant RASs to all classes in real-life DAA failures. Methods: Of the 200 virological failures that were analyzed in 197 DAA-treated patients, 89 with pegylated-interferon+ribavirin (PegIFN+RBV) and 111 without (HCV-1a/1b/1g/2/3/4=58/83/1/6/24/25; 56.8% treatment experienced; 65.5% cirrhotic) were observed. Sanger sequencing of NS3/NS5A/NS5B was performed by home-made protocols, at failure (N= 200) and w…

Summary Background We ran a compassionate use nationwide programme (ABACUS) to provide access to ombitasvir, paritaprevir, and ritonavir, with dasabuvir, plus ribavirin for hepatitis C virus (HCV) genotype 1 infection and ombitasvir, paritaprevir, and ritonavir, plus ribavirin for HCV genotype 4 infection in patients with cirrhosis at high risk of decompensation while approval of these regimens was pending in Italy. Methods In this prospective observational study, we collected data from a compassionate use nationwide programme from March 17, 2014, to May 28, 2015. Patients with HCV genotype 1 infection and cirrhosis at high risk of decompensation were given coformulated ombitasvir (25 mg), …
NT pro BNP plasma level and atrial volume are linked to the severity of liver cirrhosis.
BACKGROUND AND AIMS: Plasma levels of NT-pro-BNP, a natriuretic peptide precursor, are raised in the presence of fluid retention of cardiac origin and can be used as markers of cardiac dysfunction. Recent studies showed high levels of NT pro BNP in patients with cirrhosis. We assessed NT pro-BNP and other parameters of cardiac dysfunction in patients with cirrhosis, with or without ascites, in order to determine whether the behaviour of NT pro BNP is linked to the stage of liver disease or to secondary cardiac dysfunction. METHODS: Fifty eight consecutive hospitalized patients mostly with viral or NAFLD-related cirrhosis were studied. All underwent abdominal ultrasound and upper GI endoscop…
Sofosbuvir plus daclatasvir with or without ribavirin is safe and effective for post-transplant hepatitis C recurrence and severe fibrosis and cirrhosis: A prospective study
Background: In 2012, an Italian Named Patient Program began for hepatitis C virus (HCV)-infected liver transplant (LT) recipients with advanced fibrosis, before approval of direct antiviral agents (DAA), to benefit severely ill patients. The aim of this “real-life” study was to assess treatment efficacy and safety with an extended course of daclatasvir (DCV) plus sofosbuvir (SOF) with or without ribavirin (RBV). Methods: All HCV LT recipients with severe fibrosis in 15 Italian transplant centers were treated with DCV+SOF±RBV for 24 weeks; sustained virological response was assessed at 12 weeks post-treatment (SVR12). Results: Eighty-seven patients were enrolled (75.9% males, mean age 58.4 ±…
Clinical implications of the hyperdynamic syndrome in cirrhosis.
Abstract The hyperdynamic syndrome is a late consequence of portal hypertension in cirrhosis. The principal hemodynamic manifestations of the hyperdynamic syndrome are high cardiac output, and increased heart rate and total blood volume, accompanied by reduced total systemic vascular resistance. Pathophysiology involves a complex of humoral and neural mechanisms that can determine hemodynamic changes, and lead to hyperdynamic circulation. In this review we focus our attention on the manifestations of the hyperdynamic syndrome. Some of these are well described and directly related to portal hypertension (varices, ascites, hepatic encephalopathy, and hepatorenal syndrome), while others, such …
