Gastrointestinal manifestations of SARS-CoV-2 infection in an Italian population of hospitalized patients.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus enters the cells angiotensin-converting enzyme 2 receptor; therefore, tissues expressing this receptor are potential targets for infection. Although many studies have observed gastrointestinal (GI) symptoms in coronavirus disease 2019 (COVID-19) patients, prevalence and clinical impact are still uncertain due to the heterogeneity of reports and obstacles to generalization.

Methods: In this cross-sectional study, we included symptomatic patients requiring hospital admission, with a confirmed diagnosis of COVID-19 by nasopharyngeal polymerase chain reaction test, between 18 March and 30 May 2020.

A "One-Health" approach for diagnosis and molecular characterization of SARS-CoV-2 in Italy.

The current pandemic is caused by a novel coronavirus (CoV) called SARS-CoV-2 (species , subgenus , genus , family ). In Italy, up to the 2nd of April 2020, overall 139,422 confirmed cases and 17,669 deaths have been notified, while 26,491 people have recovered. Besides the overloading of hospitals, another issue to face was the capacity to perform thousands of tests per day.

High Efficacy and Safety of Flat-Dose Ribavirin Plus Sofosbuvir/Daclatasvir in Genotype 3 Cirrhotic Patients.

Background/aims: Patients with genotype 3 hepatitis C virus (G3-HCV) cirrhosis are very difficult to treat compared to patients with other HCV genotypes. The optimal treatment duration and drug regimen associated with ribavirin (RBV) remain unclear. To evaluate the efficacy and safety of daclatasvir (DCV)/sofosbuvir (SOF) plus a flat dose of 800 mg RBV (flat dose) compared to DCV/SOF without RBV or DCV/SOF plus an RBV dose based on body weight (weight-based) in G3-HCV patients with compensated or decompensated cirrhosis.

HepaDisk - A new quality of life questionnaire for HCV patients.

Background: Since most patients with hepatitis C virus (HCV) infection now receive treatment irrespective of liver disease severity, special attention to patient quality of life (QoL), including psycho-social aspects, is required. No QoL questionnaire is specific for patients with HCV.

Aims: To develop and validate a short Italian questionnaire (HepaDisk) assessing the QoL of patients affected by HCV with intuitive graphic results that is understandable by patients and physicians.

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.
