Chronic hepatitis B virus (HBV) infection affects millions of people worldwide and about a half million people die every year. India represents the second largest pool of chronic HBV infection worldwide with an estimated 40 million infected people. The prevalence of chronic HBV infection in pregnant women is shown to be 0.82 per cent with the risk of mother-to-child vertical transmission. Hepat...

background chronic hepatitis b virus (hbv) infection is a multifactorial disease that can result in serious clinical complications. host genetic background especially the genes that encode immunologic factors like inf-γ and its receptor (ifn-γ r) are critical in the pathogenesis of infection. materials and methods genomic dna from peripheral blood samples of 200 chronically hbv infected patient...

Approximately 350 million people worldwide are living with chronic hepatitis B virus (HBV) infection, and an estimated 620,000 die annually from complications of HBV-related liver disease [1]. In the United States, the incidence of acute HBV infection has declined substantially since 1985 as a result of the availability of effective HBV vaccines and widespread immunization of infants and high-r...

Background: The outcome of Hepatitis B virus (HBV) infection is chronic or resolved HBV infection. Over the time, the levels of HBsAg or Anti-HBs declined and were not detectable in their sera and was named as isolated anti-HBc. The purpose of this study was to assess the prevalence of isolated anti-HBc in previously HBV infected individuals.Methods: From April 2000 to September 2008, the resul...

BACKGROUND The host genetic background regulates the natural history of chronic hepatitis B virus (HBV) infection. OBJECTIVES The aim of this study was to investigate the association between TNF-α gene polymorphism in the promoter region and susceptibility to chronic hepatitis B virus infection. METHODS Four polymorphisms of TNF-α gene including -238 A/G, -308 A/G, -857 C/T, and -863 A/C we...

Background. Information regarding the progression of acute hepatitis B virus (HBV) infection to chronic infection in adults is scarce. Methods. Twenty-five adult patients with acute HBV infection (14 men and 11 women, 18-84 years old), whose clinical features progressed to those of chronic infection (group A) or did not (group B), were studied retrospectively. Results. There were 3 and 22 patie...

Background: Every year, approximately 800,000 people die from liver diseases associated with hepatitis B virus (HBV) infection. Complications outside the are common, such as fungal lung infections and viral infections. These complications may be poor immune function, thus making clinical treatment difficult increasing risk of death. Therefore, HBV-infection-related worthy attention further rese...

Background: The most common sexually transmitted diseases and the economic and social health problem throughout the world. However, vaccine coverage and antibiotic therapy and the development of programs to prevent and control major causes of acute and chronic diseases, pregnancy complications and infertility remains. Acute and chronic systemic viral infections can lead to infertility and perma...

Hepatitis B viral infection is usually a self-limiting disease in immunocompetent individuals. Chronic infection can be seen in up to 5% of infected patients. Renal manifestations of chronic HBV infection are usually glomerular. We describe here an uncommon presentation of a patient with chronic HBV infection with very high viral load and rapidly progressive renal failure. Renal biopsy showed f...

BACKGROUND Some patients with acute hepatitis B virus (HBV) infection develop chronic infection. However, the method for identifying these patients has not been established. METHODS We followed 215 Japanese patients with acute HBV infection until the clearance of hepatitis B surface antigen (HBsAg) or the development of chronic infection. Levels of HBsAg and HBV DNA were serially monitored fr...
