A total of 250 hepatitis B surface antigen positive sera were screened for antibody to hepatitis B surface antigen. It was found that seven (3%) sera showed concurrently circulating surface antigen and surface antibody to hepatitis B virus. The level of antibody to surface antigen was not affected by HBeAg and most of the cases were found in chronic hepatitis B carriers.

Delayed clearance of hepatitis B surface antigen was previously reported in a 38 year old woman after high dose chemotherapy with autologous peripheral blood stem cell rescue. Sixteen months later, this patient remained hepatitis B surface antigen negative, hepatitis B surface antibody positive, and serum hepatitis B DNA negative by polymerase chain reaction. Serial liver biopsies (one at hepat...

Background: There is a controversy about the relation between anti-hepatitis B (anti-HBs) antibody level and obesity. We designed this study to compare the vaccine efficacy in obese/overweight and non-obese cases. Methods: In this cross-sectional study, 242 obese/overweight and 85 non-obese individuals were participated. Cases were selected from a referral clinic for obesity and a referral hepa...

Background: Hepatitis B virus infection is a worldwide health problem. Vertical transmission is a route of Hepatitis B virus infection that is regarded as a considerable factor in Hepatitis B virus prevention program all over the world. Objective: This study was conducted to screen the hepatitis B surface antigen, hepatitis B surface antibody and hepatitis B e antigen in pregnant women. Methods...

Using the Staphylococcus aureus absorption method, we have modified a commercial radioimmunoassay kit for the determination of total antibody to hepatitis B core antigen so that we can now determine the predominant globulin species of that antibody. One-hundred percent of acute hepatitis B sera had a predominance of immunoglobulin M antibody to hepatitis B core antigen, whereas immunoglobulin G...

background: hepatitis e virus is an enterically transmitted virus that is endemic in south asia and this virus is one of the most important cause of acute hepatitis in this region. although hepatitis e virus (hev) is not a leading cause for chronic hepatitis, the role of hev in exacerbation of chronic liver disease is certain. materials and methods: 100 cirrhotic cases (50 hepatitis b and 50 he...

background and objective: presence of hepatitis b core antibody (anti-hbc) in the absence of hepatitis b surface antigen (hbsag) and hepatitis b surface antibody (anti-hbs) is defined, as isolated anti-hbc. little is known about the clinical significance of the isolated anti-hbc in hepatitis b virus (hbv) infections. the aim of this study was to assess the significance of anti-hbc as the only m...

introduction: lichen planus (lp) is an inflammatory mucocutaneous disease with unknown aetiology. many studies have been reported regarding probable relationship between lp and liver diseases especially hepatitis b and c and they have a lot of different consequences. these studies evaluated the relationship between lp and hepatitis b and c in hajdaee dermatology clinic in kermanshah, from 2004 ...

INTRODUCTION Hepatitis B and C coinfection is commonly seen in clinical practice. In coinfected individuals, high levels of hepatitis C viremia are often associated with low levels of serum hepatitis B DNA. Hepatitis B reactivation in hepatitis C-infected patients treated with pegylated interferon and ribavirin has been reported, but severe or fulminant reactivation is uncommon. Hepatitis C tre...
