Purpose Human immunodeficiency virus (HIV-1)-infected patients frequently harbour hepatitis B and C viruses (HBV and HCV, respectively). Possible modifications of the natural history of hepatitis B may occur. The aim of this study was to characterise HBV diversity and evolutionary and mutational viral genome profiles in HIV-1/HBV coinfections. Methods HIV-1 and HBV markers determinations (Roche,...
Purpose The prevalence of anti-hepatitis E virus (HEV) and anti-hepatitis A virus (HAV), as well as the possible links with socio-demographic and other viral risks factors, were evaluated in an inmates population. Methods The study population consisted of 973 consecutively recruited inmates of eight Italian prisons. Results The anti-HEV prevalence was 11.6 % (113/973). It increased significantly...
Aim: To evaluate the virological and clinical events occurring during a 3-year follow-up in three patients who, after symptomatic acute hepatitis C (AHC), experienced subsequent episodes of HC virus (V)-related acute liver cell necrosis. Patients and Methods: The three patients were investigated for viral variability in the core, E1/E2, and NS5b regions during different phases of infection,...
The objective of this study was to evaluate, by developing one-step real-time PCR, the outcome of superinfection with hepatitis D virus (HDV) genotype I in woodchucks that were chronic carriers of woodchuck hepatitis virus (WHV) and did not show relevant signs of liver damage. Three woodchucks (Marmota monax) chronically infected with WHV were superinfected with a woodchuck HDV inoculum. The evolution...
HCV induces endoplasmic reticulum (ER) stress which correlates with transcriptional induction of ER stress genes. Previously, we reported that expression of HCV structural proteins activates the ER stress and pro-apoptotic gene gadd153 which plays a relevant role in cell death induced by oxidative stress. In the present study, using human hepatic cell lines Huh7 carrying a full-length HCV replicon,...
Background: Health care workers (HCW) have an elevated risk of acquiring and transmitting parenteral infections. The aim of this study was to evaluate the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) markers with the final goal to encourage HBV vaccination of the non-immune Albanian HCW. Methods: Among 480 HCW enrolled, 92 were physicians, 246 were nurses/techniques, 120 were...
