Data regarding the assessment of angiogenesis in liver tissue in chronic hepatitis C (CHC) are rare. The study was performed to explain the association between the histopathological features and the number of new blood vessels in lobules and portal tracts in CHC. The second aim of the study was to define the localization of sprouting and pattern of formation of new vessels by estimating CD 34 antigen expression in the liver. The study involved 74 patients with CHC, infected with viral genotype 1b before antiviral therapy. The number of new-formatted blood vessels was positively associated with fibrosis stage and inflammatory activity grade in the liver biopsy from CHC patients. The relationship was evident in the portal tract, fibrous septa and periportal zones of lobules. The results suggest that inflammatory hepatocyte injury may promote neo-angiogenesis.

Tuberculosis and people who use drugs: why focus on this overlooked population is important and why adapted interventions are necessary.

People who use drugs show a higher incidence and prevalence of tuberculosis than people who do not use drugs in areas where Mycobacterium tuberculosis is endemic. However, this population is largely neglected in national tuberculosis programmes. Strategies for active case finding, screening, and linkage to care designed for the general population are not adapted to the needs of people who use drugs, who are stigmatised and difficult to reach.

Since 2002, it had ≥90 % reported immunization coverage for ≥3 doses of HepB (HepB3) and the birth dose (HepB-BD). However, the impact of HepB vaccination and the progress towards achieving the regional hepatitis B control and global viral hepatitis B elimination goals had not been assessed.

Hepatitis B virus (HBV) represents one of the major pathogenic factor that leads to chronic liver diseases and the development of hepatocellular carcinoma (HCC). The currently approved anti-HBV drugs cannot eradicate the virus or block the development of HCC. HBV nucleocapsid consists of the hepatitis B core antigen (HBcAg) and the HBV relaxed-circular partially double-stranded DNA (rcDNA), indispensable in virus replication.

Hepatitis E Virus (HEV) is a globally widespread pathogen that causes acute hepatitis infection. Beyond hepatic pathogenesis, HEV has been proven to cause several extrahepatic manifestations, such as neurological, renal, and hematological manifestations. It was also associated with mortality in pregnant females.

Achieving HBsAg seroclearance is a key goal in treating chronic hepatitis B virus (HBV) infection but remains difficult with nucleos(t)ide analogues (NAs). Tenofovir alafenamide fumarate (TAF), a recommended NA for managing chronic HBV infection (CHB), has uncertain effects on HBsAg levels and potential adverse events when used long-term after switching from entecavir (ETV). We retrospectively evaluated 77 CHB patients, including 47 who switched from ETV to TAF with a median follow-up of 40 months post-switch and a median of 60 months of HBsAg monitoring pre-switch.
