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 auxiliary workers and 22 were office workers.

Results: The HBsAg, anti-HBc and anti-HCV prevalence were 8.1%, 70% and 0.6%, respectively. The highest (11.4%) HBsAg prevalence was observed in the youngest age group (20-30 years of age). High HBsAg prevalence (7.2-7.5%) was detected also in age groups above 30 years. The highest HBsAg prevalence (12.6%) was found in the auxiliaries. The anti-HBc prevalence increased significantly with age from 59% in HCWs younger than 39 years to 87% among those older than 50 years. After adjustments for different job categories, age older than 40 years remained independently associated with anti-HBc positivity (OR = 2.9; 95% CI 1.9-4.6) and inversely associated with the lack of HBV immunity or infection markers (OR = 0.4; 95% CI 0.2-0.7). Of 142 HBsAg negative and/or anti-HBc Ab negative sera, 28 (20%) tested positive for anti-HBs. The 114 remaining individuals with no HBV infection or immunity markers were vaccinated against HBV infection.

Conclusions: A high HBV infection rate and low HBV vaccination coverage were found in Albanian HCW. Albania is a Mediterranean country still highly endemic for HBV infection and new strategies to promote HBV vaccination are to be adopted.

Homeobox protein MSX-1 restricts hepatitis B virus by promoting ubiquitin-independent proteasomal degradation of HBx protein.

Hepatitis B virus (HBV) X protein (HBx) is a key factor for regulating viral transcription and replication. We recently characterized homeobox protein MSX-1 (MSX1) as a host restriction factor that inhibits HBV gene expression and genome replication by directly binding to HBV enhancer II/core promoter (EnII/Cp) and suppressing its promoter and enhancer activities. Notably, HBx expression was observed to be repressed more drastically by MSX1 compared to other viral antigens.

Hepatitis B virus (HBV) infection is a major global health concern, with liver transplantation (LT) serving as a critical treatment for end-stage liver disease caused by HBV. However, the risk of HBV reinfection after LT remains significant, necessitating effective prophylaxis. Today, the combination of hepatitis B immune globulin (HBIG) and high-barrier nucleos(t)ide analogues (NUCs) is the standard of care for preventing HBV recurrence post-LT but concerns about the cost of HBIG and access to high-barrier NUCs have led to a reduction in the use, dose, and duration of HBIG in recent years.

Background: Patients with chronic hepatitis B virus (HBV) infection are characterized by impaired immune response that fails to eliminate HBV. Immune checkpoint molecules (ICMs) control the amplitude of the activation and function of immune cells, which makes them the key regulators of immune response.

Methods: We performed a multiparametric flow cytometry analysis of ICMs and determined their expression on intrahepatic lymphocyte subsets in untreated and treated patients with HBV in comparison with non-pathological liver tissue.

Background: Inflammation is a critical component in the process of resolved hepatitis B virus (HBV) infection. The neutrophil-to-lymphocyte ratio (NLR) serves as a sensitive indicator of systemic inflammation and immune activation. Our study aimed to investigate the correlation between elevated NLR levels and the risk of all-cause mortality in patients with resolved HBV infection.
