Hepatitis B: changes in epidemiological features of Afro-descendant communities in Central Brazil.

Hepatitis B virus (HBV) infection is still a concern in vulnerable populations. In a study performed by our team in 1999-2003 in two Afro-Brazilian communities, Furnas dos Dionísios (FD) and São Benedito (SB), high prevalence rates of HBV exposure (42.7% and 16.

High level of exposure to hepatitis B virus infection in a vulnerable population of a low endemic area: A challenge for vaccination coverage.

Objectives: To evaluate the epidemiological and molecular features of HBV infection among recyclable waste collectors.

Methods: The participants were recruited from the dumping ground and recycling cooperatives in Campo Grande, Brazil, and were screened for hepatitis B and C, and HIV serological markers by ELISA, confirmed by PCR.

Results: Among 278 participants, 63.

HCV-Mediated Apoptosis of Hepatocytes in Culture and Viral Pathogenesis.

Chronic Hepatitis C Virus (HCV) infection is associated with progressive liver injury and subsequent development of fibrosis and cirrhosis. The death of hepatocytes results in the release of cytokines that induce inflammatory and fibrotic responses. The mechanism of liver damage is still under investigation but both apoptosis and immune-mediated processes may play roles.
