Effectiveness of test-and-treat model with direct-acting antiviral for hepatitis C virus infection in migrants: a prospective interventional study in Italy.

Background: Migrants, mainly undocumented and low-income refugees, are at high risk of hepatitis C virus (HCV) infection, but are a difficult-to-reach and to-treat population. The aim of the study was to evaluate the effectiveness of a test and treat model with direct-acting antiviral for HCV infection in these migrants coming from low-income and living in southern Italy.

Methods: A prospective, multicenter, collaborative study based on a four-phase-program (educational counseling, screening, linkage-to-care and treatment) was designed in southern Italy; the study started in June 2018, was stopped in February 2020 because of the outbreak of SARS-CoV2 infection in Italy and was resumed in February 2021 until November 2021.

An Unusual Case of a Double Tricuspid and Mitral Valves Infective Endocarditis Complicated by Multiple Septic Embolisms Secondary to an Atrial Septal Defect: A Case Report and Review of Literature.

Multivalvular endocarditis (MVE) is an uncommon infection that mostly involves mitral and aortic valves, and it is related to a higher risk of congestive heart failure and a higher mortality. We described a case of a bilateral MVE and performed a review of the literature on similar clinical cases. We reported an unusual case of a 68-year-old male patient with a tricuspid and mitral infective endocarditis due to a methicillin-resistant complicated by multiple right- and left-sided septic embolization (lungs, brain, spleen, L2-L3 vertebral bones) due to an unknown atrial septal defect identified and repaired during cardiac surgery.

Efficacy and safety of tixagevimab-cilgavimab (Evusheld®) in people with Multiple Sclerosis on Ocrelizumab: preliminary evidence.

Background: Evusheld (EVS) was authorized by FDA and EMA as pre-exposure prophylaxis (PrEP) in people at high risk of severe Covid-19 outcomes, including people with Multiple Sclerosis (pwMS) on B-cell depleting (BCD) therapies-such as Ocrelizumab (OCR). In this population, no data on possible adverse drug reactions (ADRs) to EVS, B-lymphocytes (CD20 +) counts pre- and post-EVS injection, and comparison of percentage increase of IgG antibodies directed against SARS-CoV-2 trimeric spike protein (anti-TSP IgG) post-EVS and Covid-19 vaccine was available. The aim of this study was to better characterize the efficacy and safety profile of EVS in pwMS on BCD agents.

COVID-19 as Another Trigger for HBV Reactivation: Clinical Case and Review of Literature.

Universal hepatitis B virus (HBV) vaccination has been applied for years in most countries, but HBV infection remains an unresolved public health problem worldwide, with over one-third of the world's population infected during their lifetime and approximately 248 million hepatitis B surface antigen (HBsAg) chronic carriers. HBV infection may reactivate with symptomatic and sometimes life-threatening clinical manifestations due to a reduction in the immune response of various origins, due to chemotherapy or immunosuppressive therapy, treatments increasingly practiced worldwide. SARS-CoV-2 and its COVID-19 associated disease have introduced new chances for HBV reactivation due to the use of dexamethasone and tocilizumab to counteract the cytokine storm.

Cardiovascular disease risk in liver transplant recipients transplanted due to chronic viral hepatitis.

Background: Cardiovascular disease (CVD) is a major cause of morbidity and mortality after liver transplantation, mostly in patients transplanted for nonalcoholic steatohepatitis, obesity and diabetes. Few data exist on cardiovascular diseases among patients transplanted for viral hepatitis.

Objective: Our aim is to clarify the cardiovascular risk and subclinical vascular damage among liver transplant recipients for chronic viral hepatitis (i.

Changing epidemiology of patients treated with direct acting antivirals for HCV and persistently high SVR12 in an endemic area for HCV infection in Italy: real-life 'LIver Network Activity' (LINA) cohort update results.

Burden, risk assessment, surveillance and management of SARS-CoV-2 infection in health workers: a scoping review.

Background: Health workers (HWs) are at increased risk for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection and a possible source of nosocomial transmission clusters. Despite the increased risk, the best surveillance strategy and management of exposed HWs are not yet well known. The aim of this review was to summarize and critically analyze the existing evidence related to this topic in order to support public health strategies aimed at protecting HWs in the hospital setting.

Direct acting antivirals treatment for hepatitis C virus infection does not increase the incidence of de novo hepatocellular carcinoma occurrence: Results from an Italian real-life cohort (LINA cohort).

The effectiveness of direct-acting antivirals (DAAs) against hepatitis C virus (HCV) infection is ascertained. However, some authors raised the issue of an increased incidence of de novo hepatocellular carcinoma (HCC) in patients treated with DAAs. Aim of the study was to evaluate the rate of HCC occurrence in a real-life cohort of patients who received anti-HCV treatment with DAAs.

Efficacy of the "first wave" Direct Acting antivirals against HCV infection: results from the Italian LINA (Liver Network Activity) cohort.

Approximately 71 million people are chronically infected with HCV worldwide. Recently, interferonfree therapies effective against HCV became available and nowadays, therapeutic strategies include a combination of two or three drugs with different mechanisms of action. In the present study, we reported real-life SVR rates in a large cohort of four prescribing centers in a high-endemic area of Southern Italy.

Interferon-free regimens improve kidney function in patients with chronic hepatitis C infection.

Background And Aim: The impact of directly acting antiviral agent (DAA) regimens on renal function is not well defined and quite controversial. We evaluated the effect of DAAs on kidney function and the factors associated with an improvement or worsening.

Patients And Methods: The changes in estimated glomerular filtration rate (eGFR) in a cohort of 403 patients treated with a DAA regimen were evaluated.

Background: Direct-acting antivirals (DAAs) are safe and effective for the treatment of HCV infection. However, data regarding their efficacy in patients with Child-Pugh B cirrhosis are scarce and their capability in improving liver function is debated. The aim of our study was to assess the clinical benefits of treatment with DAA in subjects with Child-Pugh B cirrhosis.

Low prevalence of HTLV1/2 infection in a population of immigrants living in southern Italy.

Aims: To assess the prevalence of HTLV-1 and HTLV-2 infections in a cohort of immigrants living in southern Italy.

Findings: We screened for antibody to HTLV-1/2 infection 1,498 consecutive immigrants born in endemic areas (sub-Saharan Africa or southern-Asia) by a commercial chemiluminescent microparticle immunoassay. If confirmed in a Western blot assay, which differentiates anti-HTLV-1 from anti-HTLV-2, the positive sera were tested for specific HTLV RNA by a home-made PCR.

HCV genotype-3h, a difficult-to-diagnose sub-genotype in the DAA era.

Background: No data are available on the clinical presentation and virological pattern in the case of failure of interferon (IFN)-free regimens in patients with genotype-3h. In this paper authors identified the virological and clinical characteristics of patients with genotype-3h treated with suboptimal or not indicated IFN-free regimens for the misclassification of HCV genotype.

Methods: A total of 87 consecutive patients with failure to an IFN-free regimen were re-tested for HCV genotype by HCV NS5B sequencing; the 26 patients identified as harbouring HCV-3 were enrolled.

Virological patterns of HCV patients with failure to interferon-free regimens.

The study characterized the virological patterns and the resistance-associated substitutions (RASs) in patients with failure to IFN-free regimens enrolled in the real-life setting. All 87 consecutive HCV patients with failed IFN-free regimens, observed at the laboratory of the University of Campania, were enrolled. All patients had been treated with DAA regimens according to the HCV genotype, international guidelines, and local availability.

ITPase activity modulates the severity of anaemia in HCV-related cirrhosis treated with ribavirin-containing interferon-free regimens.

Background: To investigate the association between inosine triphosphatase (ITPase) activity and the degree of anaemia occurring during direct-acting antiviral (DAA)/ribavirin (RBV)-based therapy in patients with cirrhosis.

Methods: In a multicentre, prospective study 227 patients with HCV-related cirrhosis treated with DAA and RBV were enrolled. All patients were screened for the rs1127354 and rs7270101 ITPA single nucleotide polymorphisms using direct sequencing.

Prevalence of latent tuberculosis infection in healthcare workers at a hospital in Naples, Italy, a low-incidence country.

Background: Healthcare workers (HCWs) are at higher risk than the general population of contracting tuberculosis (TB). Moreover, although subjects with latent TB infection (LTBI) are asymptomatic and are not infectious, they may eventually develop active disease. Thus, a fundamental tool of TB control programs for HCWs is the screening and treatment of LTBI.

Hepatitis B virus and hepatitis C virus infection in healthcare workers.

Approximately 3 million healthcare workers per year receive an injury with an occupational instrument, with around 2000000 exposures to hepatitis B virus (HBV) and 1000000 to hepatitis C virus (HCV). Although an effective HBV vaccine has been available since the early eighties, and despite the worldwide application of universal vaccination programs started in the early nineties, HBV still remains a prominent agent of morbidity and mortality. There is no vaccine to limit the diffusion of HCV infection, which progresses to chronicity in the majority of cases and is a major cause of morbidity and mortality worldwide due to a chronic liver disease.
