Platelet aggregation indicating antigen-antibody complex formation was observed when hepatitis B surface (HBs) antigen and antibody were mixed. Platelet aggregation titers were determined for serum specimens found positive by radioimmunoassay for either HBs antigen or HBs antibody. From these determinations, incidence of HBs antigen-antibody complexes was found to be higher in HBs antigen seraa...

conclusions results demonstrated the relatively high prevalence of hcv infection in the patients. applying sensitive methods to screen blood units is recommended to minimize the risk of transfusion associated hepatitis. objectives the current study aimed to evaluate characteristics of hepatitis in patients with β-tm visiting imam khomeini hospital of zabol, in sistan and baluchistan province of...

abstract background thalassemia patients that are conventionally treated by a regular transfusion regimen are exposed to blood born viral infections.the aim of this study was to investigate the seroprevalence of hepatitis b virus (hbv), hepatitis c virus (hcv) , and human immunodeficiency virus(hiv) among all multitransfused thalassemia patients in west north of iran. material and methods a ret...

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...

unresponsiveness to hepatitis b surface antigen (hbsag) has been shown to be associated with dysfunction of the presenting cells (apc) and defect in the specific b-lymphocyte and/or t-lymphocyte repertoires.   direct determination of the frequency of specific t-lymphocytes together with complementary analysis of the naive circulating immune cells could provide valuable information about the cel...

Hepatitis B core antigen (HBc Ag) and hepatitis B surface antigen (HBs Ag) were detected in the liver tissue of a patient with chronic aggressive hepatitis by the immunofluorescent complement technique. The presence of anti-HBc was examined by the same method in 67 human sera previously tested for HBs Ag, anti-HBs and s-GPT levels. HBc Ag was localized mainly in the nucleus and sometimes in the...

A study was made of latent hepatic diseases in university students. 1.4% to 1.6% of the students were positive for hepatitis B surface antigen (HBsAg), and 10.3% for anti-HBs. Of 28 students with HBs-antigenemia, 2 had chronic persistent hepatitis, and 3 minimal hepatitis, 23 being healthy carriers. Hepatitis B e-antigen (HBeAg) was detected in 44% of the students with HBsAg, and anti-HBe in 13...
