BACKGROUND Infections contracted during infancy or childhood are responsible for 42 percent of case of chronic hepatitis B disease, and in 25 percent or more these infections result in death from hepatoma or cirrhosis during adulthood. Hepatitis B vaccine and immune globulin provide the means of preventing the disease and its sequelae, but their proper use requires clinical strategies for decid...

We develop mathematical models for the role of hepatitis B e-antigen in creating immunological tolerance during hepatitis B virus infection and propose mechanisms for hepatitis B e-antigen clearance, subsequent emergence of a potent cellular immune response, and the effect of these on liver damage. We investigate the dynamics of virus-immune cells interactions, and derive parameter regimes that...

conclusions fulminant hepatitis b is associated with distinct mutational patterns of hbv, underlining that genomic diversity of the virus is an important factor determining its pathogenicity. results the most commonly detected diversities affect regulatory motifs of hbv in the core and s region, indicating that these alterations may convert the virus to an aggressive strain. moreover, mutations...

It is not known how the immune system targets hepatitis C virus (HCV)-infected HLA-mismatched hepatocytes under immune-suppressed conditions after orthotopic liver transplantation (OLT). In addition, the relationship between the HCV-specific immune response and IL28B variants as predictors of HCV clearance has not been well-characterized. We determined the IL28B polymorphisms for 57 post-OLT HC...

there is a well-recognized relationship between aplastic anemia and viral hepatitis. clinically apparent hepatitis precedes aplastic anemia by a period of weeks to months. hepatitis is an infrequent cause of aplastic anemia and is usually severe and fatal if untreated. the clinical features and, particularly the response to immunosuppressive therapy strongly suggest that immune mechanisms media...

introduction: hepatitis c virus (hcv) infection is a major public health problem which influences about 170 million people worldwide. different types of vaccines have been designed using hcv structural proteins to control the viral infection. the core nucleocapsid protein is one of the most conserved proteins and a desirable target for hcv vaccines, especially the protein-based vaccines. in cur...

We report a case of a 15-year-old boy with autoimmune hepatitis lacking common serologic markers and normal gammaglobulinemia associated with immune thrombocytopenia and family history of psoriasis. He presented to our department with a 4-year history of a cervical posterior lymphadenopathy and recent petechiae. Previous laboratory results 6 months before already showed hepatocellular injury. A...

Hepatitis A is common in children and usually is a self-limiting disease. Although extrahepatic and hematological immune manifestations following acute hepatitis A virus (HAV) infection have rarely been reported, they are frequently observed in other viral hepatitis. In this paper, we report the case of a 3-year-old girl who developed immune thrombocytopenic purpura (ITP) and hemolytic anemia a...

Abstract Combined immune checkpoint blockade (CICB) targeting CTLA-4 and PD-1 has improved the prognosis for many malignancies, but also occurred a high rate of immune-related adverse events (irAEs). The manifestation these toxicities is an important limiting factor successful implementation CICB, restraining its anti-tumor efficacy. Carbon monoxide (CO), pivotal endogenous signaling molecule, ...
