Liver disease, particularly viral hepatitis, is increasingly common. The most frequent causes of long-term, or chronic, viral hepatitis are persistent infections with the hepatitis B or hepatitis C virus. Worldwide, 400 million people are chronic carriers of the hepatitis B virus [1]. Each year, between 500,000 to 1.2 million people die from progression of this viral infection, making it the 10...

SUMMARY To investigate the relationship between studying in the field of laboratory sciences and some of markers of Hepatitis B virus, the prevalence of Hepatitis Bs Ag, Hepatitis Be Ag and their antibodies, were studied in 423 students of Tehran Universities. Using the enzyme linked immunosorbent assay (ELISA) method, it was found that 1.4 % of laboratory sciences students possessed HBsAg,9% ...

Serum samples from 214 blood donors in the United Kingdom who were carriers of hepatitis B surface antigen (HBsAg) were examined for hepatitis B virus deoxyribonucleic acid (DNA) by DNA:DNA hybridisation and for hepatitis B e antigen (HBeAg) and its antibody. One fifth of the donors carried infectious virus in their circulation. The presence of hepatitis B virus DNA correlated well with that of...

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...

Liver transplantation is an excellent treatment for hepatitis B virus infected patients who have acute or chronic liver failure and/or primary liver cancer. Advances in antiviral prophylaxis prevent clinically significant graft re-infection for the majority of patients. Graft and patient survival has improved significantly during the past decade, and results of transplantation for hepatitis B v...

background: hepatitis b with its complications has become one of the universal problems. injection drug use is one of the most important risk factors in the transmission of hepatitis b. therefore, we assessed hepatitis b virus prevalence among cases with a history of intravenous drug use (ivdu) as the first announcement-based study in this regard. materials and methods: the announcement based d...

background torque teno virus (ttv) belongs to the circoviridae family and was separated from japanese patients with elevated levels of serum alanine transferase for the first time. following this, extensive studies have been carried out around the world. objectives the present study was designed to investigate and determine the frequency of ttv genotypes in patients with chronic hepatitis b and...

By using an amplification-created restriction site method, the precore TAG mutant of hepatitis B virus was detected in 6 (75%) of 8 acute fulminant hepatitis B patients, 7 (58%) of 12 acute self-limiting hepatitis B patients, 35 (81%) of 43 hepatitis B virus surface antigen carriers with fulminant hepatitis, and 42 (70%) of 60 hepatitis B virus surface antigen carriers with chronic hepatitis. T...

INTRODUCTION Co-infections between hepatitis B and HIV viruses are frequent due to their similar epidemiological characteristics. Worldwide, hepatitis B infection is one of the main causes of hepatocellular carcinoma and cirrhosis. In Cuba as elsewhere, prevalences of hepatitis B and hepatitis C viral infections are higher in persons with HIV. These hepatitis viruses act as opportunistic infect...

INTRODUCTION After the initiation of a mass hepatitis B vaccination program in Taiwan, the prevalence of hepatitis B virus infection has declined progressively. However, about 1 percent of the young generation, who received hepatitis B vaccination at birth, remain carriers. Infection with vaccine-escape hepatitis B virus mutants always occurs shortly after birth. Here, we report two female sibl...
