BACKGROUND Coinfection with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) is common. Most studies have concentrated on the effects of chronic HIV infection on HBV infection; however, studies on the effects of acute HIV infection on HBV infection are especially important to elucidate the potential mechanisms leading to complications from HIV/HBV coinfection. METHODS We evaluat...

BACKGROUND Since the introduction of Highly Active Anti-Retroviral Therapy and the dramatic improvement in the prognosis of individuals with Human Immunodeficiency Virus, liver disease due to chronic viral hepatitis has become as important cause of morbidity and mortality in co-infected individuals. The objective of the study was to determine the Sero-prevalence of Hepatitis B Virus, Hepatitis ...

rs12979860 in interleukin 28B (IL28B) gene is associated with response to interferon-α therapy and natural viral clearance in hepatitis C. The role of this polymorphism is less known in hepatitis B virus (HBV) infection. We evaluated whether rs12979860 was associated with outcomes of HBV infection. There were 651 individuals with persistent infection (387 with liver cirrhosis, 264 without cirrh...

Studies on the prevalence of infection with hepatitis B virus (HBV) among children are scarce in Latin American countries, especially in Mexico. This study was aimed to investigate the prevalence of HBV infection, occult hepatitis B infection (OBI) and HBV genotypes among children with clinical hepatitis. In total, 215 children with clinical hepatitis were evaluated for HBV infection. HBV serol...

Background and Aims: End-stage renal disease patients treated by hemodialysis (HD) are more susceptible for infection by viral hepatitis and human immunodeficiency virus (HIV) infections. Infection by these viruses is promoted by the characteristic immunological dysfunction that develops in renal failure and interferes with the patient's ability to eliminate these viruses. Prevalence of these v...

Vaccination against hepatitis B virus (HBV) immediately after birth prevents neonatal infection by vertical transmission from HBV carrier mothers. There is an ongoing debate whether infant vaccination is sufficient to protect against infection when exposed to HBV later in life. We studied 222 Thai infants born to HBsAg -/+ and HBeAg -/+ mothers who were vaccinated with recombinant hepatitis B v...

Asymptomatic hepatitis B infection is characterized as a type of hepatitis in which hepatitis B surface antigen is present in the patient's peripheral blood despite the absence of clinical symptoms. Previous studies have shown that a particular genotype may effect clinical manifestations of hepatitis B infection; hence, the aim of the current study was to determine the frequency of hepatitis B ...

Background: In patients who are hepatitis B virus (HBV) DNA-positive, but HBV surface antigen (HBsAg) -negative, the infection is referred to as occult hepatitis B infection (OBI). Occult HBV infection is harmful when other liver diseases are present, and can aggravate liver damage in in patients with chronic liver diseases. In human immunodeficiency virus (HIV) infection the suppression of vir...

In a 4-month period, 216 cases of acute viral hepatitis were diagnosed in adults at the Infectious Diseases Hospital, Athens, Greece. Twenty-six percent of these were hepatitis B surface antigen negative. A full set of clinical specimens was obtained from 19 of these patients, who were studied in depth for the etiology of their hepatitis. A total of 7 of the 19 patients had serological evidence...
