Hepatitis B virus (HBV) is hepatotropic and lymphotropic. HBV-infected individuals have an increased risk of developing malignant lymphoma, and the HBV infection rate in lymphoma patients is significantly higher than that in the general population. However, the exact mechanism and correlation between HBV infection and lymphoma onset and progression currently remain unclear. We retrospectively a...

OBJECTIVE Infection with hepatotropic viruses is associated with a variable degree of liver disease, and there is evidence that more severe lesions are related to the association with another viral infection. The aim of this investigation is to establish the relationship between different viral infections occurring in the same individual and the presence and progression of liver disease. DESI...

hepatitis b infection is the main cause of liver related mortality in many countries including iran. liver transplantation in cirrhosis due to hbv infection before 1990 was an absolute contraindication. recurrent infection was a significant event in post liver transplant setting and resulted in increased risk of graft failure and death except successful transplanted individuals. advances in ant...

Background: Infection with hepatitis B, C, and delta viruses (HBV/HCV/HDV) caused by mother-to-child transmission (MTCT) is still a serious health problem worldwide. Coinfection HBV/HDV or HCV has been shown to accelerate the progression of chronic HBV infection, resulting in higher mortality. Objectives: The aim this study was evaluate prevalence anti-HCV, anti-HDV, anti-HIV antibodies mothers...

China has one of the world's highest rates of hepatitis B infection. Over the past 20 years, a series of strategies have been implemented to prevent infection with the hepatitis B virus (HBV) in China. These strategies include hepatitis B (hepB) immunization for susceptible populations such as infants and young children and for high-risk populations such as health care workers and patients, pre...

BACKGROUND Occult infection with hepatitis B virus (HBV) is a type of chronic HBV infection that is characterized by the absence of a detectable hepatitis B surface antigen in the blood and by very low levels of HBV DNA in the blood and liver. The mechanisms leading to occult HBV infection remain poorly understood but include possible genetic mutations and deletions. Recently, it has been shown...

BACKGROUND Drug-related infectious diseases are among the major health consequences of drug use, and any existing drug-related infection may predispose injecting drug users (IDUs) to other infections. METHODS We assessed among IDUs in Budapest, Hungary the prevalence of and vulnerability to selected drug-related infections and co-infections. The sample consisted of 186 participants recruited ...

BACKGROUND Acute hepatitis A virus (HAV) infection can cause severe hepatitis especially in patients with underlying chronic liver disease. In patients with pre-existing chronic hepatitis B (HBV) acute HAV infection can suppress HBV replication. The exact mechanism of HBV suppression during acute HAV infection is still a subject of debate. One mechanism may be the production of HAV infection-in...
