Factors Enhancing Treatment of Hepatitis C Virus-Infected Italian People Who Use Drugs: The CLEO-GRECAS Experience.

Introduction: We assessed the performance of direct-acting antivirals (DAAs) in hepatitis C virus (HCV)-infected people who use drugs (PWUDs) in terms of sustained virological response (SVR) and adherence rates in comparison to a location-matched cohort of non-PWUD HCV patients.

Methods: All consecutive HCV RNA-positive PWUDs were enrolled between 2015 and 2019. All subjects underwent DAA treatment according to international guidelines and then followed, at least, up to 12 weeks after the end of treatment (SVR12).

Sustained virological response in patients with HCV treated with daclatasvir plus sofosbuvir, with or without ribavirin: a large, field-practice study.

Background: The once-daily oral combination of daclatasvir (DCV) and sofosbuvir (SOF), with or without ribavirin (RBV), is effective and well tolerated in patients with hepatitis C virus (HCV). However, further field-practice studies are necessary to investigate the effectiveness and safety of the DCV+SOF combination in diverse subpopulations of patients with HCV, including those who are more challenging to treat such as patients with a genotype 3 (G3) infection. The aim of this retrospective, multicenter, field-practice study was to investigate the therapeutic efficacy and safety of the oral combination of DCV and SOF, with or without RBV (DCV+SOF±RBV), in a large unselected cohort of patients with chronic HCV infection (CHC).

Mitochondrial toxicity and body shape changes during nucleos(t)ide analogues administration in patients with chronic hepatitis B.

Our study purpose was to evaluate mitochondrial (mt)DNA and RNA in peripheral blood mononuclear cells (PBMCs) and body shape changes (BSC) in HBV-infected patients. mtDNA and mtRNA were measured in PBMCs. The presence of BSC was evaluated through a questionnaire and clinical evaluation.

Rate of non-response to ursodeoxycholic acid in a large real-world cohort of primary biliary cholangitis patients in Italy.

Response to ursodeoxycholic acid (UDCA) is crucial for the prediction of primary biliary cholangitis (PBC) prognosis, and different response criteria were validated and proposed by reference centers for PBC. To date, rates of non-response to UDCA from real-world series are lacking. Hepatology/Gastroenterology centers belonging to 'Club Epatologi Ospedalieri' (CLEO) and 'Associazione Italiana Gastroenterologi Ospedalieri' (AIGO) were invited to participate in the study, and asked to extract all patients followed for PBC, without any selection or exclusion, and fill in the database provided.

DNMT1 modulation in chronic hepatitis B patients and hypothetic influence on mitochondrial DNA methylation status during long-term nucleo(t)side analogs therapy.

Inhibition of viral replication is the most important goal in patients with Hepatitis B virus chronic infection (CHB). Currently, five oral nucleo(t)side analogs (NAs), including Lamivudine, Adefovir, Telbivudine, Entecavir, and Tenofovir, have been approved for treatment. The widespread use of NAs has also been linked with a progressive growth of unlikely anomaly attributable to mitochondrial dysfunctions, not previously recognized.

Wilson's disease in two consecutive generations: the detection of three mutated alleles in the ATP7B gene in two Sardinian families.

Background: Wilson's disease diagnosis is still a challenge for clinicians.

Aim: To underline the importance of genetic testing in carrier detection and diagnosis of atypical Wilson's disease cases.

Methods: Two families with Wilson's disease in two consecutive generations were analysed with clinical, biochemical and genetic testing.

Skin reaction in antiviral therapy for chronic hepatitis C: a role for polyethylene glycol interferon?

In the past decade, different modalities of antiviral therapy have been adopted aimed at eradicating hepatitis C virus infection. Initially, interferon was used in monotherapy, then interferon combined with ribavirin and amantadine. Recently, interferon has been conjugated with polyethylene glycol to allow optimization of its pharmacokinetic properties and to improve its antiviral activity.
