Chronic hepatitis C virus infection is attributed as a cause of circulating mixed cryoglobulinemia and immune mediated extrahepatic complications. Massive pulmonary haemorrhages with chronic hepatitis C has been scarcely reported; and has been associated with renal failure and cryoglobulinemia. The most commonly used treatment modalities include the use of cyclophosphamide, prednisolone, and pl...

During inflammatory processes, immunocompetent cells are exposed to substantial amounts of free radicals and toxic compounds. Glutathione is a cysteine-containing tripeptide that an important ubiquitous antioxidant molecule produced in human organs. The intracellular content GSH regulates the detoxifying capacity cells, as well immune response. particularly liver, where it serves major non-prot...

Title of Document: INTERFERENCE OF HOST INNATE IMMUNE RESPONSE BY HEPATITIS E

Acute-on-chronic liver failure (ACLF) is a syndrome characterized by acute and severe decompensation of chronic disease (CLD) correlated with multiple organ failure, poor prognosis, increased mortality. In 40–50% ACLF cases, the trigger not recognized; for many these patients, bacterial translocation associated systemic inflammation thought to be determining factor; in other 50% sepsis, alcohol...

Hepatitis B flare, defined as an event with abrupt rise of alanine aminotransferase (ALT) levels to >5 times the upper limit of normal during chronic hepatitis B virus (HBV) infection, is considered to be the result of a human leukocyte antigen-I restricted, cytotoxic T lymphocyte mediated immune response against HBV and its downstream mechanisms. It may occur spontaneously, during or after ant...

Under most circumstances, HBV is not cytopathic and it is the immune response of the host that determines the outcome of infection. The most complete immune response is associated with the most severe liver injury and the greatest likelihood of viral clearance, whereas an immature immune response leads to chronic hepatitis. The natural history of chronic hepatitis B is similar to that of acute ...

Hepatitis B vaccine has been available worldwide since the mid-1980s. This vaccine was evaluated in a clinical trial in Thailand, conducted on subjects born to hepatitis B surface antigen positive and hepatitis B e-antigen positive mothers and vaccinated according to a 4-dose schedule at 0, 1, 2 and 12 mo of age and a single dose of hepatitis B immunoglobulin concomitantly at birth. All enrolle...

Hepatitis B virus (HBV) is a hepadnavirus that is a major cause of acute and chronic hepatitis in humans. Hepatitis B viral infection itself is noncytopathic, and it is the immune response to the viral antigens that is thought to be responsible for hepatic pathology. Previously, we developed a transgenic mouse model of primary HBV infection and demonstrated that the acute liver injury is mediat...

BACKGROUND The role of regulatory CD4 T cells (Treg) in immune-mediated liver disease is still under debate. It remains disputed whether Treg suppress T cell-mediated hepatitis in vivo and whether hepatic regulatory T cells are functional in patients with autoimmune hepatitis. METHODS We used TF-OVA mice, which express ovalbumin in hepatocytes, to investigate the impact of Treg in a model of ...

Abstract Systems of time-delay differential equations are widely used to study the dynamics infectious diseases and immune responses. The Marchuk-Petrov model is one them. Stable non-trivial steady states stable periodic solutions this can be interpreted as chronic viral diseases. In work we briefly describe our technology developed for computing systems present discuss results with parameter v...
