results the mean age of chb patients was 38.5± 11.9 years and 55.9% of them (231 patients) were male. there were 13 cases (3.1%) with hdv infection. there was no association between positive anti-hdv serology and factors such as age, gender, carrier state, liver enzymes, and positive hepatitis b e antigen (hbeag) serology. conclusions although hdv had a low prevalence in our area, it is importa...

An increasing number of infertile, hepatitis B virus-infected individuals have opted for assisted reproductive technology. However, the impact of the hepatitis B virus carrier serostatus on neonatal outcomes has not been evaluated. Data from 504 patients who delivered singletons were analyzed. In females, hepatitis B surface antigen, hepatitis B e antigen, and antibody to hepatitis core antigen...

The prevalence of antibodies to hepatitis B core antigen in 552 prime blood donors was of 9.4%. The majority (71.2%) has antibodies to hepatitis B surface antigen. The hepatitis B surface antigen was present in 0.7%, all of them antibodies to hepatitis B core antigen positive.

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.

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...

 ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...

literature review shows that hepatitis c infection may increase the risk of non-hodgkin lymphoma. reactivation of hepatitis b infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. we present hepatitis b surface (hbs) antigenemia and concurrent hepatitis c virus (hcv) seropositivity in a case of hairy cell leukemia. key words: hairy cell leukemia...

In patients undergoing chemotherapy for the treatment of malignant disease, the reactivation of hepatitis B virus in hepatitis B surface antigen-positive patients has been frequently reported. However, activation has also been reported in hepatitis B surface antigen-negative patients who test positive for hepatitis B core antibody and/or hepatitis B surface antibody, who were thought to have ha...
