Case of Fatal Hepatitis Related to HEV-3 Infection in Central Italy.

Hepatitis E virus (HEV) is a global health problem, causing an estimated 20 million infections annually. Thus, the management of HEV requires special consideration. In developed countries, hepatitis E is mainly recognized as a foodborne disease (mainly transmitted via undercooked meat consumption) that is generally caused by genotype 3 and 4 circulating in various animals, including pigs and wild boars.

Hepatitis E Virus Infection in Patients with Systemic and Cutaneous Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by a multifactorial etiology in which genetic and environmental factors interplay. An exclusively cutaneous condition has been described and defined as cutaneous lupus erythematosus (CLE). In Italy, a nationwide blood donor survey found an overall HEV prevalence of 8.

HEV-3 subtypes and strains detected in cases of HEV infection in central Italy from 2015 to 2023.

Purpose: HEV is an emerging pathogen in Europe and was previously shown to be hyperendemic in areas of Abruzzo and Lazio, Central Italy. No systematic analysis of the HEV strains responsible for human infections over several years in Central Italy has previously been reported. Aim of the study was the molecular characterization of HEV from autochthonous hepatitis E cases occurred in Abruzzo and Lazio between 2015 and 2023.

Chronic inflammatory demyelinating polyneuropathy and HEV antibody status: A case-control study from Lazio, Italy.

Introduction: Few studies have pointed to the possible role of infectious diseases in triggering Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP). Given the association of Hepatitis E Virus (HEV) with Guillain Barrè syndrome, we conducted a case-control study to determine the possible association of HEV infection with CIDP, analyzing possible risk factors for acquiring HEV infection in both CIDP patients and controls.

Materials And Methods: 82 CIDP and 260 from the general population have provided some personal information (demographics, anamnestic data and recognized risk factors for HEV infection) and underwent venipuncture blood sampling for virological assays testing for anti-HEV IgG and IgM with ELISA and RNA-HEV performing RT-PCR.

Epidemiological and molecular characterization of HBV and HCV infections in HIV-1-infected inmate population in Italy: a 2017-2019 multicenter cross-sectional study.

HIV-1 subtyping showed that 77.

Prevalence of HEV infection in acute non-ABC hepatitis and prognostic role of extrahepatic manifestations.

Background: HEV-3 and HEV-4 are emerging cause of zoonotic acute hepatitis in high-income countries. In Europe the disease is underdiagnosed but hyperendemic areas have been identified. We describe a population with acute non-ABC (n-ABC) hepatitis in Abruzzo, the Italian region with the highest seroprevalence reported.

Hepatitis B and C virus infection in patients with Systemic and Cutaneous Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by a multifactorial etiology. The primary aim of this study was to estimate HCV and HBV infection prevalence in a cohort of SLE and Cutaneous Lupus Erythematosus (CLE). We assessed the frequency of these infections in our cohort and the possible associations with disease clinical/laboratory features and disease activity status.

Molecular Characterization of Hepatitis B Virus Infection in a Patient with Cutaneous Lupus Erythematosus.

Hepatitis B virus (HBV) infection is a serious global health problem. Patients with autoimmune diseases, such as Lupus Erythematosus, are exposed to a higher risk of acquiring infections. In this study, a molecular characterization, genomic investigation of the Hepatitis B virus, polymerase (P) and surface (S) genes, from a patient affected by Cutaneous Lupus Erythematosus (CLE), was presented.

Post-exposure prophylaxis with sotrovimab for Omicron (B.1.1.529) SARS-CoV-2 variant during the aplastic phase of autologous stem cell transplantation.

Methods: We describe the outcomes of a Multiple Myeloma (MM) patient, who was threateningly exposed to the Omicron (B.1.

Hepatitis E Outbreak in the Central Part of Italy Sustained by Multiple HEV Genotype 3 Strains, June-December 2019.

In European countries, autochthonous acute hepatitis E cases are caused by Hepatitis E Virus (HEV) genotype 3 and are usually observed as sporadic cases. In mid/late September 2019, a hepatitis E outbreak caused by HEV genotype 3 was recognized by detection of identical/highly similar HEV sequences in some hepatitis E cases from two Italian regions, Abruzzo and Lazio, with most cases from this latter region showing a link with Abruzzo. Overall, 47 cases of HEV infection were finally observed with onsets from 8 June 2019 to 6 December 2019; they represent a marked increase as compared with just a few cases in the same period of time in the past years and in the same areas.

Retrospective analysis of acute HBV infections occurred in 1978-79 and 1994-95 in North-East Italy: increasing prevalence of BCP/pre-core mutants in sub-genotype D3.

Background: At the end of the 1970s, in Italy more than 2% of the general population was HBsAg carrier. In the late '70s and late '80s, two remarkable events might have impacted on HBV strains transmitted in North-East Italy: (a) the increased HBV incidence due to parenteral drugs between 1978 and 1982; (b) the preventive anti-HIV educational campaign, started locally in 1985.

Methods: To address if those events impacted on circulating HBV variants, acute cases occurred in North-East Italy in 1978-79 (n = 50) and 1994-95 (n = 30) were retrospectively analysed.

Hepatitis E virus infection prevalence among men who have sex with men involved in a hepatitis A virus outbreak in Italy.

Background: The routes of hepatitis E virus (HEV) transmission have still not been fully clarified. Here, we evaluated the possibility of sexual transmission of HEV, which remains a highly disputed issue.

Materials And Methods: Hepatitis E virus sexual transmission risk was assessed by comparing the prevalence of HEV infection in a sample of 196 Italian men who have sex with men (MSM) involved in a multi-country hepatitis A virus (HAV) outbreak, and in 3,912 Italian male blood donors selected from the same regions and provinces as the MSM.

Sensitivity of hepatitis C virus rapid tests in detecting antibodies in general population.

Background: Evaluation of clinical performance of the anti-hepatitis C virus (HCV) rapid tests were carried out mostly in chronic hepatitis C patients and in individuals at high risk of HCV infection.

Methods: The aim of this study was to evaluate the performance of OraQuick and Wantai rapid tests on archived serum samples from 1408 individuals (mean age 46, range 18-90; 65% female) recruited with a systematic sampling procedure during a general population survey.

Results: The analysis of samples by Ortho HCV 3.

Incidence of hepatitis E virus infection among blood donors in a high endemic area of Central Italy.

In Europe, autochthonous hepatitis E virus (HEV) infection is mainly a foodborne zoonosis, but it is also transmitted by blood transfusion. Despite the numerous prevalence surveys, only a few studies have investigated HEV incidence. We aimed to determine HEV incidence and risk factors among blood donors in a hyperendemic area in Central Italy.

Haematological immune-related adverse events induced by anti-PD-1 or anti-PD-L1 immunotherapy: a descriptive observational study.

Background: Anti-programmed cell death 1 (PD-1) and anti-programmed cell death ligand 1 (PD-L1) antibodies are novel immunotherapies for cancer that can induce immune-related adverse events (irAEs). These adverse events can involve all organs, including the haemopoietic system. Thus far, haematological irAEs (haem-irAEs) have not been extensively characterised.

Hepatitis E virus genotypes and subgenotypes causing acute hepatitis, Bulgaria, 2013-2015.

Background: In industrialized areas of the world, including Europe, Hepatitis E Virus (HEV) is considered an emerging pathogen. In fact, autochthonous cases caused by HEV genotype 3 (HEV-3) are increasingly reported. Several studies described the human HEV-3 subtypes and strains circulating in West Europe countries; in contrast, very little is known about the HEV strains responsible for acute hepatitis E in countries of East Europe/Balkans, such as Bulgaria.

A nationwide retrospective study on prevalence of hepatitis E virus infection in Italian blood donors.

Background: In Europe, hepatitis E virus (HEV) infection is mainly a food-borne zoonosis, but it can also be transmitted by blood transfusion. It is usually a mild and self-limited infection. However, immunocompromised persons, who are also those more likely to undergo blood transfusions, may develop chronic hepatitis and often cirrhosis.

Hepatitis a virus genotypes and strains from an endemic area of Europe, Bulgaria 2012-2014.

Background: Hepatitis A virus (HAV) infection is endemic in Eastern European and Balkan region countries. In 2012, Bulgaria showed the highest rate (67.13 cases per 100,000) in Europe.

Correlates of infection and molecular characterization of blood-borne HIV, HCV, and HBV infections in HIV-1 infected inmates in Italy: An observational cross-sectional study.

Coinfection of blood-borne hepatitis B and hepatitis C viruses (HBV and HCV, respectively) in human immunodeficiency virus type 1 (HIV-1)-positive individuals frequently occurs in inmate population and peculiar viral strains and patterns of virological markers may be observed.Plasma from 69 HIV-1-positive inmates was obtained from 7 clinical centers connected with correctional centers in different towns in Italy. HIV, HBV, and HCV markers were tested by commercial assays.

High prevalence of anti-hepatitis E virus antibodies among blood donors in central Italy, February to March 2014.

Prevalence of anti-hepatitis E virus (HEV) antibodies is highly variable in developed countries, which seems partly due to differences in assay sensitivity. Using validated sensitive assays, we tested 313 blood donors attending a hospital transfusion unit in central Italy in January and February 2014 for anti-HEV IgG and IgM and HEV RNA. Data on HEV exposure were collected from all donors.

Evaluation of rapid tests for diagnosis of acute hepatitis E.

Background: Hepatitis E virus diagnosis still presents difficulties due to discordant results among diagnostic tests.

Objectives: The aim of this study was to evaluate the performance of two rapid tests for detection of anti-HEV IgM antibodies.

Study Design: The rapid tests were compared with three commercial anti-HEV ELISA assays and one Real-Time PCR assay on 59 sera from patients with acute viral non-AC hepatitis.

Key Role of Sequencing to Trace Hepatitis A Viruses Circulating in Italy During a Large Multi-Country European Foodborne Outbreak in 2013.

Background: Foodborne Hepatitis A Virus (HAV) outbreaks are being recognized as an emerging public health problem in industrialized countries. In 2013 three foodborne HAV outbreaks occurred in Europe and one in USA. During the largest of the three European outbreaks, most cases occurred in Italy (>1,200 cases as of March 31, 2014).
