Chronic hepatitis C is a major worldwide health problem with an estimated prevalence of 1.6-2%. The prognosis of chronic hepatitis C depends on the rate of fibrosis progression which, over a ...20-30-year time span, may determine the risk of developing cirrhosis and its complications, namely hepatocellular carcinoma, liver decompensation, hepatic encefalopathy and espohageal variceal bleeding. The only therapeutic measure able to halt this progressive process is HCV eradication by interferon (IFN)-based therapies. HCV clearance benefits patients with chronic hepatitis C, by preventing the progression to cirrhosis, as well as those with established cirrhosis, by effectively reducing the risk of liver-related complications. The latest innovation in anti-HCV treatment has been the pegylation of the IFN molecule through the attachment of one or more polyethylene glycols to the IFN molecule, drastically modifying the immunological, pharmacokinetic and pharmacodynamic properties of the drug. Following the demonstration of a more potent antiviral effect in terms of sustained virological response rates in Phase III randomized trials, pegylated IFN coupled with ribavirin has become the standard of care for chronic hepatitis C. Currently, two forms of pegylated IFN exist (α2a and α2b), which differ significantly in terms of pharmacokinetics and dynamics, is whether these peculiarities translate into different efficacy rates being still being debated.
Background
Failure of anti-hepatitis C therapy encompasses both primary non-response and post-treatment relapse. Treatment failure to pegylated interferon (PEG-IFN)-α2b and ribavirin (RBV) largely ...depends upon virus genotype, but the interaction between genotype, cirrhosis and pattern of treatment failure is unclear. We aimed to assess whether cirrhosis modifies the pattern of PEG-IFN-α2b and RBV treatment failure.
Methods
A total of 471 treatment-naive patients with histologically proven chronic hepatitis C virus (HCV) infection (106 with cirrhosis; 185 with HCV genotype 1 HCV-1, 157 with HCV genotype 2 HCV-2, 92 with HCV genotype 3 HCV-3 and 37 with HCV genotype 4 HCV-4) were consecutively treated with PEG-IFN-α2b 1.5 μg weekly and weight-based RBV.
Results
The sustained virological response (SVR) rates were 31% in HCV-1 and HCV-4, 80% in HCV-2 and 72% in HCV-3, and were lower in cirrhotic than in non-cirrhotic HCV-1 and HCV-4 (17% versus 36%; P=0.01), and HCV-3 (33% versus 79%; P=0.001), but not HCV-2 (69% versus 83%; P=0.1) patients. Treatment failure was the consequence of lower end-of-treatment response rates (37% versus 53%; P=0.06) plus higher post-treatment relapse rates (55% versus 31%; P=0.07) in cirrhotic HCV-1 and HCV-4 patients and higher rates of post-treatment relapse in HCV-2 (29% versus 10%; P=0.01) and HCV-3 cirrhotic patients (61% versus 12%; P<0.001). By multi-variate analysis, HCV-1 and HCV-4 (odds ratio OR 7.44, 95% confidence interval CI 4.87–11.36), and cirrhosis (OR 3.00, 95% CI 1.80–5.00) were independent predictors of treatment failure.
Conclusions
Cirrhosis is an important moderator of SVR, accounting for different patterns of treatment failure in patients infected with different genotypes.
The association between nonalcoholic fatty liver disease (NAFLD) and carotid atherosclerosis is still controversial. The present study was designed to assess the relationship between left ventricular ...systolic mechanics, noninvasively assessed by two-dimensional (2D) speckle-tracking echocardiography (STE) and common carotid artery (CCA) intima-media thickness (IMT), in patients with nonadvanced NAFLD.
All consecutive NAFLD patients diagnosed with liver stiffness measurement (LSM) <12.5 kPa on transient elastography between September 2021 and December 2021 were prospectively enrolled. All participants underwent blood tests, transient elastography, 2D transthoracic echocardiography (TTE) implemented with 2D-STE analysis of left ventricular (LV) global longitudinal strain (GLS) and finally carotid ultrasonography. Main independent predictors of subclinical atherosclerosis, defined as CCA-IMT >0. 9 mm, were evaluated.
A total of 92 NAFLD patients (54.0 ± 11.1 years, 50% males) were prospectively analyzed. Mean LSM was 6.2 ± 2.4 kPa. FibroScan results revealed that 76.1% of patients had F0-F1, 5.4% F2 and 18.5% F3 liver fibrosis. Despite normal biventricular systolic function on 2D-TTE, LV-GLS was reduced (less negative than -20%) in 64.1% of patients. However, 62.0% of NAFLD patients were found with CCA-IMT >0. 9 mm. Age odds ratio (OR),1.19; 95% confidence interval (CI), 1.05-1.36, hypertension (OR, 3.73; 95% CI, 1.53-9.11), LSM (OR, 4.83; 95% CI, 2.43-9.59), LV-GLS (OR, 0.49; 95% CI, 0.36-0.68) and statin therapy (OR, 0.10; 95% CI, 0.02-0.60) were independently associated with subclinical atherosclerosis. Age ≥51 years, LSM ≥5.5 kPa and LV-GLS less negative than -20% were the best cutoff values for predicting subclinical atherosclerosis.
Subclinical myocardial dysfunction and subclinical atherosclerosis are simultaneously present in patients with nonadvanced NAFLD.

•Glecaprevir/pibrentasvir combination has demonstrated excellent SVR rates (99.2%) in this real-world study in Italy.•Male gender (0.022) and HCV genotype3 (0.046) were associated ...with the lowest rates of SVR after 8-week G/P treatment.•8.3% of the patients reported mild adverse events and 0.7% of them prematurely withdrew antiviral treatment.
The efficacy and safety of glecaprevir/pibrentasvir (G/P) for patients infected with hepatitis C virus (HCV) have only been investigated in clinical trials, with no real-world data currently available. The aim of our study was to investigate the effectiveness and safety of G/P in a real-world setting.
All patients with HCV consecutively starting G/P between October 2017 and January 2018 within the NAVIGATORE-Lombardia Network were analyzed. G/P was administered according to drug label (8, 12 or 16 weeks). Fibrosis was staged either histologically or by liver stiffness measurement. Sustained virological response (SVR) was defined as undetectable HCV-RNA 12 weeks after the end of treatment.
A total of 723 patients (50% males) were treated with G/P, 89% for 8 weeks. The median age of our cohort was 58 years, with a median body mass index of 23.9 kg/m2, and median liver stiffness measurement of 6.1 kPa; 84% were F0-2 and 16% were interferon-experienced. Median HCV-RNA was 1,102,600 IU/ml, and 49% of patients had HCV genotype 1 (32% 1b), 28% genotype 2, 10% genotype 3 and 13% genotype 4. The median estimated glomerular filtration rate was 90.2 ml/min, platelet count 209x103/mm3 and albumin 4.3 g/dl. The SVR rates were 94% in intention-to-treat and 99.3% in per protocol analysis (8-week vs. 12 or 16-week: 99.2% vs. 100%). Five patients failed therapy because of post-treatment relapse; a post-treatment NS5A resistance-associated substitution was detected in 1 case. SVR rates were lower in males (p = 0.002) and in HCV genotype-3 (p = 0.046) patients treated for 8 weeks, but independent of treatment duration, fibrosis stage, baseline HCV-RNA, HIV co-infection, chronic kidney disease stage and viral kinetics. Mild adverse events were reported in 8.3% of the patients, and 0.7% of them prematurely withdrew treatment. Three patients died of drug-unrelated causes.
In a large real-world cohort of Italian patients, we confirmed the excellent effectiveness and safety of G/P administered for 8, 12 or 16 weeks.
A large number of patients with hepatitis C virus have been treated with glecaprevir/pibrentasvir (G/P) within the NAVIGATORE-Lombardia Network, in Italy. This is the first real-world study evaluating effectiveness and safety of G/P in patients with hepatitis C virus treated according to international recommendations. This study demonstrated excellent effectiveness (with sustained virological response rates of 99.3%) and safety profiles.

Hepatocellular carcinoma (HCC) is an increasingly frequent cause of mortality in hemophiliacs with chronic viral hepatitis. Early diagnosis of the tumor at an initial stage is known to improve the ...outcome of HCC treatment. Because all HCC cases detected in a previous study based upon annual ultrasound (US) surveillance of hemophiliacs with elevated alanine aminotransferase levels were multinodular, this study was designed to evaluate if a more intense surveillance with US and alphafetoprotein (AFP) serum levels of all the patients infected with the hepatitis C virus (HCV) improved the identification of single nodule tumors. A multicenter cohort of 559 HCV-infected hemophiliacs was divided into 2 arms, one followed up at 6-month intervals and one at 12-month intervals depending on the choice and available facilities of each treatment center. During a 6-year surveillance period, HCC was diagnosed in 5 (2.4%) of 210 patients in the 6-month group and in 3 (0.9%) of 349 patients in the 12-month group. The overall incidence rate of HCC was 239 per 100 000 per year (397 per 100 000 per year in the 6-month group and 143 per 100 000 per year in the 12-month group; differences not statistically significant). By multivariate analysis, HCC risk was increased 12.9-fold with alcohol intake more than 80 g/d and 15.2-fold with AFP levels higher than 11 ng/mL. Liver-related death occurred in 8 cases (1.4%), including 3 with HCC. Still alive and tumor free after 24 to 34 months from diagnosis are 3 patients with multinodular tumors treated with repeat chemoembolization followed by orthotopic liver transplantation. In conclusion, 6-month surveillance with US did not increase the chances of detection of single nodule tumors, but it is reasonable to assume that successful treatment of multinodular tumors based upon debulking with chemoembolization and liver transplantation was facilitated by this approach.

•SOF/VEL/VOX demonstrated excellent effectiveness in patients with HCV and previous DAA failure in a real-life study.•Cirrhosis (p = 0.005) and hepatocellular carcinoma onset ...(p = 0.02) were the only features associated with treatment failure.•Treatment failures (4%) occurred in patients with cirrhosis, with genotypes HCV-1a and 3 the most represented.
Sofosbuvir/velpatasivr/voxilaprevir (SOF/VEL/VOX) is approved for retreatment of patients with HCV and a previous failure on direct-acting antivirals (DAAs), however real-life data are limited. The aim of this study was to assess the effectiveness and safety of SOF/VEL/VOX in a real-life setting.
All consecutive patients with HCV receiving SOF/VEL/VOX between May-October 2018 in 27 centers in Northern Italy were enrolled. Bridging fibrosis (F3) and cirrhosis (F4) were diagnosed by liver stiffness measurement: >10 and >13 kPa respectively. Sustained virological response (SVR) was defined as undetectable HCV-RNA 4 (SVR4) or 12 (SVR12) weeks after the end-of-treatment.
A total of 179 patients were included: median age 57 (18–88) years, 74% males, median HCV-RNA 1,081,817 (482–25,590,000) IU/ml. Fibrosis stage was F0-F2 in 32%, F3 in 21%, F4 in 44%. HCV genotype was 1 in 58% (1b 33%, 1a 24%, 1nc 1%), 2 in 10%, 3 in 23% and 4 in 9%; 82% of patients carried resistance-associated substitutions in the NS3, NS5A or NS5B regions. Patients received SOF/VEL/VOX for 12 weeks, ribavirin was added in 22% of treatment schedules. Undetectable HCV-RNA was achieved by 74% of patients at week 4 and by 99% at week 12. Overall, 162/179 (91%) patients by intention to treat analysis and 162/169 (96%) by per protocol analysis achieved SVR12, respectively; treatment failures included 6 relapsers and 1 virological non-responder. Cirrhosis (p = 0.005) and hepatocellular carcinoma (p = 0.02) were the only predictors of treatment failure. Most frequent adverse events included fatigue (6%), hyperbilirubinemia (6%) and anemia (4%).
SOF/VEL/VOX is an effective and safe retreatment for patients with HCV who have failed on a previous DAA course in a real-life setting.
This is the largest European real-life study evaluating effectiveness and safety of sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) in a large cohort of consecutive patients with hepatitis C virus infection and a prior direct-acting antiviral failure, who were treated within the NAVIGATORE Lombardia and Veneto Networks, in Italy. This study demonstrated excellent effectiveness (98% and 96% sustained virological response rates at week 4 and 12, respectively) and an optimal safety profile of SOF/VEL/VOX. Cirrhosis and hepatocellular carcinoma onset were the only features associated with treatment failure.

We describe the case of a 51-year-old woman with HCV-associated cryoglobulinemic glomerulonephritis (GN). She presented mild deterioration of kidney function, non-nephrotic proteinuria, and active ...urinary sediment. Kidney biopsy showed features of membranoproliferative changes with some sclerosis. Sustained viral response (SVR) was obtained by 6 months of antiviral therapy (peg-IFN-α2a plus ribavirin). SVR was linked with improvement of kidney function and remission of proteinuria. Clinical and virological remission persists over a 25-month follow-up. This case report emphasizes efficacy and safety of antiviral treatment of HCV-associated glomerulonephritis – preliminary but encouraging results exist. We identified by systematic review of the literature 9 studies (156 unique patients); the pooled estimate of frequency of sustained virological response after IFN-based therapy was 0.49 (95% confidence interval, CI: 0.21, 0.77; p < 0.0005; random effects model). Heterogeneity was found (I2 = 98.9%, p < 0.0001). Two possible regimens should be considered for the treatment of HCV-associated cryoglobulinemic GN according to the clinical presentation. Immunosuppressive therapy is recommended for HCV-related kidney disease having aggressive course, and recent evidence supports rituximab (RTX) use with a reduced exposure to corticosteroids. We identified six studies (66 unique patients) on RTX therapy for HCV-associated kidney disease; at the end of RTX therapy, the pooled estimate of the mean decrease in proteinuria was 1.4 g/24 h (95% CI: 0.75, 2.05, p < 0.001); The p test for heterogeneity gave a value of 0.94 (I2 = 0). Several questions related to RTX use remain. HCV-induced GN is uncommon among CKD patients of developed countries, and this clearly hampers prospective controlled clinical trials aimed to evaluate efficacy and safety of antiviral or immunosuppressive therapy in this population.
