Some studies have suggested that hepatitis E virus is more frequent in human immunodeficiency virus (HIV) patients and can progress to chronic infection. We aimed to determine the prevalence of hepatitis E virus antibodies and RNA in a series of 100 HIV-infected patients in Tehran, Iran, with comparison to 52 healthy HIV, hepatitis B and C-negative blood donors as controls. HIV-infected patient...

conclusions the hav seroprevalence of 90.8% in the studied region may be representative of a highly endemic region of hav that does not require a vaccination program to be commissioned. results it was found that 455 out of 501 (90.8%) serum samples, including those of 211 (42.1%) men and 290 (57.9%) women, were positive for hav igg antibody. education level, age, marital status, and ethnicity w...

Background: Acute Viral Hepatitis (AVH) is a major health problem worldwide, with higher incidence in developing countries, like India. The most common cause of viral hepatitis specific group hepatic viruses A, B, C and E (HAV, HBV, HCV HEV). Their clinical manifestations range from asymptomatic to acute fulminant or chronic hepatitis. Exploring the etiological spectrum clinic-epidemiological p...

Objectives. We estimated seroprevalence and correlates of selected infections in pregnant women and blood donors in a resource-limited setting. Methods. We performed a cross-sectional analysis of laboratory seroprevalence data from pregnant women and voluntary blood donors from facilities in Cameroon in 2014. Rapid tests were performed to detect hepatitis B surface antigen, syphilis treponemal ...

The purpose of the present study was to measure the amount of antibody to hepatitis B core antigen (anti-HBc) in different populations by the immunoelectroosmophoresis method. High titers of anti-HBc, up to 1/4,096, were found in the acute stage of hepatitis B virus infections and in the chronic carrier state of hepatitis B surface antigen. In cases of acute hepatitis the anti-HBc titers gradua...

background: health care workers (hcw) are at high risk of contracting various infectious diseases and play a dual role in the transmission of infections in health care facilities. objective: to determine the seroprotection against hepatitis b, measles, rubella, and varicella among hcws in a community hospital in qatar. methods: this is a cross-sectional survey conducted in a 75-bed community ho...

Celiac disease has been associated with other autoimmune disorders such as autoimmune hepatitis, moreover it is known that T cell mediated immune response to dietary gluten and released cytokines are important for the entheropathy seen in celiac disease. We investigated celiac autoantibodies in patients with autoimmune hepatitis (AIH), and chronic hepatitis B (CHB).Sera from 84 patients with Au...

A quantitation procedure for hepatitis B core antigen (HBcAg) in serum without prior removal of antibodies to HBcAg is described. The virus nucleoprotein core was released from hepatitis B virus (HBV) particles by treatment with Nonidet P-40 detergent and allowed to form immune complexes with homologous antibodies to HBcAg present in the sera of HBV-infected individuals. After precipitation wit...

The disappearance of the e antigen and the appearance of anti-e antigen antibodies are two biomarkers that indicate favorable prognosis in Hepatitis B. In this study the Advanced Quality immunochromatographic test for detecting those biomarkers was compared to the Vidas semi-quantitative ELISA test. Our hypothesis was that it is possible to use these biomarkers measured in a rapid and simple Ad...

Hepatitis B vaccine has been available worldwide since the mid-1980s. This vaccine was evaluated in a clinical trial in Thailand, conducted on subjects born to hepatitis B surface antigen positive and hepatitis B e-antigen positive mothers and vaccinated according to a 4-dose schedule at 0, 1, 2 and 12 mo of age and a single dose of hepatitis B immunoglobulin concomitantly at birth. All enrolle...
