Unlabelled: An important tool to explore personal experience of symptoms, treatment and clinical outcome is stratification of illness perception in patients affected by PBC. Aim: To assess the perception of illness in a cohort of Italian patients with PBC. Methods: Between June and December 2019, a specific questionnaire was administered to a pool of 210 patients from 7 tertiary Italian centers, in order to identify and assess the patient's past history, symptoms and their impact on the quality of life, follow-up, treatment and perceived satisfaction of patients toward the provided care. Results: Fatigue, pruritus, and abdominal discomfort and sicca syndrome were present in 50.4%, 45%, 30.4% and 28.5% of patients, fatigue having the most impacting the daily-life. After a consultation with a specialist, the diagnosis of PBC was met within 18 months for 143 patients. Patients were mostly concerned about possible health problems that occur and in 25% of cases, symptoms had a negative impact on their life. Eighty percent of patients said they were satisfied with efficacy and tolerability of treatment, while 26% requested an improvement in the relationship with the specialist. Conclusions: The results highlight the importance of both promoting timely referral to the specialist and facilitating communication between healthcare professionals and patients.

The aim of this study was to identify a method for staging hepatic fibrosis using a non-invasive, rapid and inexpensive technique based on ultrasound morphologic hepatic features. A total of 215 patients with different liver diseases underwent B-mode (2-D brightness mode) ultrasonography, vibration-controlled transient elastography, 2-D shear wave elastography and measurement of the controlled attenuation parameter with transient elastography. B-Mode images of the anterior margin of the left lobe were obtained and processed with automatic Genoa Line Quantification (GLQ) software based on a neural network for staging liver fibrosis. The accuracy of GLQ was 90.6% during model training and 78.9% in 38 different patients with concordant elastometric measures. Receiver operating characteristic curve analysis of GLQ performance using vibration-controlled transient elastography as a reference yielded areas under the curves of 0.851 for F ≥ F1, 0.793 for F ≥ F2, 0.784 for F ≥ F3 and 0.789 for F ≥ F4. GLQ has the potential to be a rapid, easy-to-perform and tolerable method in the staging of liver fibrosis.

Background: Comprehensive and contemporary data pertaining large populations of patients with Primary Biliary Cholangitis (PBC) and hepatocellular carcinoma (HCC) are missing. Aim: To describe main characteristics and outcome of PBC patients with HCC diagnosed in the new millennium. Methods: Analysing the Italian Liver Cancer registry we identified 80 PBC patients with HCC diagnosed after the year 2000, and described their clinical characteristics, access to treatment and survival. Results: Median age of patients was 71 years and 50.0% were males. Cirrhosis was present in 86.3% of patients, being well-compensated in 58.0%. Median HCC diameter was smaller in patients under surveillance (2.6vs 4.0cm, P=0.007). Curative treatment, feasible in 50.0% of patients, was associated with improved survival compared to palliative and supportive care (42vs 33vs 6 months, P

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 system. Diagnostic accuracy was estimated using the area under the receiver operating characteristic curves(AUROCs) for advanced fibrosis (Ludwig stage≥III). The effects of biochemical and clinical parameters on liver stiffness measurement (LSM) were appraised. Derivation cohort consisted of 126 patients with valid LSM and LB, VCTE identified patients with advanced fibrosis with AUROC of 0.89. LSM cut-offs ≤6.5kPa and >11.0kPa enabled to exclude and confirm, respectively, advanced fibrosis (negative predictive value[NPV]=0.94, positive predictive value[PPV]=0.89, error rate=5.6%). These values were externally validated in an independent cohort of 91 PBC patients(NPV=0.93, PPV=0.89, error rate=8.6%). Multivariable analysis found the only parameter affecting LSM was fibrosis stage. No association was found with BMI and liver biochemistry. Conclusions In a multicenter study of treatment-naive PBC patients, we identified two cut-offs (LSM≤6.5kPa and>11.0kPa) able to discriminate at diagnosis the presence or the absence, respectively, of advanced fibrosis in PBC patients, with external validation. In patients with LSM between these two cut-offs, VCTE is not reliable and liver biopsy should be evaluated for accurate disease staging. BMI and liver biochemistry did not affect LSMs.

Introduction The association between hepatitis C virus (HCV) infection and B-cell non-Hodgkin’s Lymphomas (NHL) is well established. Antiviral therapy (AVT) is the first-line treatment for HCV-related indolent NHL whereas diffuse large B-cell lymphoma (DLBCL) requires immediate start of chemoimmunotherapy (CIT), usually deferring AVT. However, an early HCV elimination may reduce the risk of CIT-induced liver toxicity and consequent CIT interruption or withdrawal. To date few data are available on safety and efficacy of concomitant administration of direct-acting antivirals (DAA) and CIT in HCV-associated DLBCL. Methods 7 consecutive patients (5 males, median age 65 years) with HCV infection (four genotype 2a/2c, two genotype 1b, one genotype 4; one patient with compensated cirrhosis) and DLBCL received different DAA regimens concurrently with CIT. Results All patients completed the scheduled AVT and CIT with neither interruption nor withdrawal of the latter. One case of neutropenia was observed during concomitant therapy, no liver toxicity occurred. All patients achieved sustained virological response and complete DLBCL response (median follow-up of 12 months). Conclusions Concomitant administration of DAA and CIT for HCV-associated DLBCL is safe and may prevent CIT-induced liver toxicity. Large, prospective studies are needed to confirm these preliminary data and to assess prognostic implications.

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 aminotransferase (ALT) at 12 months. Safety and tolerability were also assessed. Results We analysed 191 patients until at least 12 months of follow-up. Median age was 57 years, 94% female, 61 (32%) had cirrhosis, 28 (15%) had histologically proven overlap with autoimmune hepatitis (PBC-AIH). At 12 months, significant median reductions of ALP (-32.3%), ALT (-31.4%), and bilirubin (-11.2%) were observed. Response rates were 42.9% according to Poise criteria, and 11% by normal range criteria. Patients with cirrhosis had lower response than patients without cirrhosis (29.5% vs. 49.2%, p = 0.01), owing to a higher rate of OCA discontinuation (30% vs. 12%, p = 0.004), although with similar ALP reduction (29.4% vs. 34%, p = 0.53). Overlap PBC-AIH had a similar response to pure PBC (46.4% vs. 42.3%, p = 0.68), with higher ALT reduction at 6 months (-38% vs. -29%, p = 0.04). Thirty-three patients (17%) prematurely discontinued OCA because of adverse events, of whom 11 experienced serious adverse events. Treatment-induced pruritus was the leading cause of OCA discontinuation (67%). Conclusions Effectiveness and safety of OCA under real-world conditions mirror those in the Poise trial. Patients with cirrhosis had lower tolerability. Overlap PBC-AIH showed higher ALT reduction at 6 months compared with patients with pure PBC. Lay summary Obeticholic acid (OCA) was shown to be effective in more than one-third of patients not responding to ursodeoxycholic acid in a real-world context in Italy. Patients with cirrhosis had more side effects with OCA, and this led to suspension of the drug in one-third of patients. OCA was also effective in patients who had overlap between autoimmune hepatitis and primary biliary cholangitis., Graphical abstract, Highlights • Under real-world conditions, OCA was effective in ~43% of patients who were non-responders to UDCA, according to Poise criteria. • Patients with cirrhosis showed lower efficacy (29.5%), mainly attributed to reduced tolerability and higher discontinuation rate. • Patients with overlap AIH-PBC showed a comparable efficacy to pure PBC, with a higher ALT reduction at 6 months. • Most patients with PBC are still in need of additional therapy if aiming to normalise liver biochemistry.

Obeticholic acid (OCA) improves cholestasis and is generally well tolerated in patients with primary biliary cholangitis (PBC) not responding, or intolerant, to ursodeoxycholic acid (UDCA). As PBC is mainly a cholestatic disorder, less attention is paid to aminotransferase behavior in the course of treatment. In this study we evaluated, in clinical practice, the efficacy of OCA treatment on both alkaline phosphatase (ALP) and alanine aminotransferase (ALT) using updated healthy ranges for aminotransferases. Fifteen PBC patients, non-responders to UDCA, were evaluated at baseline and during OCA treatment with serial measurement of cholestasis indexes and ALT, that were also assessed using updated normal ranges (

Background and Aims: Tenofovir disoproxil fumarate (TDF) is recommended for chronic hepatitis B (CHB) treatment, but it may induce kidney dysfunction whose management is not yet known. This Italian, multicentre, retrospective study aimed to assess the efficacy and safety of switching to entecavir (ETV) patients who developed TDF-associated glomerular and/or tubular dysfunction. Methods: A total of 103 TDF-treated patients were included as follows: age 64years, 83% male, 49% cirrhotics, 98% with undetectable HBV DNA, 47% with previous lamivudine resistance (LMV-R) and 71% previously treated with adefovir. Twenty-nine (28%) were switched to ETV because estimated glomerular filtration rate (eGFR MDRD ) was

Backgound A significant proportion of hepatitis B surface antigen (HBsAg) negative/anti-hepatitis B core antigen (anti-HBc) positive patients with non-Hodgkin lymphoma (NHL) undergoing rituximab-based chemotherapy (R-CT) may suffer hepatitis B virus (HBV) reactivation. Aims We wanted to assess efficacy and safety of lamivudine (LMV) prophylaxis to prevent this complication. Methods Eighty-five consecutive HBsAg negative/anti-HBc positive NHL patients (71 years, 100% serum HBV DNA undetectable, 74% anti-HBs positive) received LMV coadministered with R-CT and for 18 months after the end of R-CT. Serum ALT, HBsAg, anti-HBs and HBV DNA were assessed every 4 months during and after end of LMV. Results During 39 (2–108) months of study period, including 21 months of LMV and 27 additional months after LMV discontinuation, one patient (2%) had HBV reactivation, 31 months after stopping LMV and during administration of new immunosuppressive regimens, without LMV prophylaxis, owing to incomplete oncological response. A 50% decline of anti-HBs titers occurred in 22/63 (35%) patients, including 12 who became anti-HBs seronegative. Five (6%) patients had ALT increase during R-CT but none required R-CT discontinuation. Seventeen (20%) patients died, all for tumour progression. Conclusion LMV prophylaxis is safe and effective in preventing HBV reactivation in HBsAg negative/anti-HBc positive NHL patients receiving R-CT.

Objective. To investigate the relationship between insulin resistance and viral load decay in nondiabetic and noncirrhotic genotype 1 chronic HCV patients during peginterferon and ribavirin treatment and the possible influence of BMI and leptin as metabolic confounders.Methods. 75 consecutive noncirrhotic, nonobese, and nondiabetic patients with genotype 1 chronic hepatitis C treated with peginterferon alpha 2a plus ribavirin were evaluated. HOMA-IR, serum leptin, and BMI were measured in all patients at baseline and at weeks 12 and 48, whereas viral load was measured at the same time points and then 24 weeks after the end of treatment.Results. HOMA-IR was significantly associated with both BMI and leptin at baseline. During peginterferon plus ribavirin treatment, there was a significant reduction of HOMA-IR at weeks 12 and 48 from baseline (P=0.033and 0.048, resp.) in patients who achieved an early viral load decay (EVR), a trend not observed in patients who not achieved EVR. No variations during treatment were observed regarding BMI and leptin irrespective of EVR.Conclusion. The early reduction of HOMA-IR but not of BMI and leptin during antiviral treatment in noncirrhotic, chronic hepatitis C genotype 1 patients who achieved EVR suggests a viral genesis of insulin resistance in patients with nonmetabolic phenotype.
