results hepatitis b surface antigen (hbsag) was found in 122/3000 (4.1%) prisoners. hepatitis b e antigen (hbeag), anti-hiv, anti-hcv and anti-hiv/anti-hcv were detected in 52/122 (42.6%), 12/122 (10%), 22/122 (18%) and 3/122 (2.4%) prisoners, respectively. the hbv-dna was found in 115/122 (94.3%) prisoners. the most high risk behavior was to utilize the collaborative syringe by injecting drug ...

we measured the prevalence of hbv surface antigen (hbsag) among male injection drug users (idus) in detention, tehran, iran. a cross-sectional survey included 499 male idus arrested by police during a predetermined police sweep in tehran (february, 2006). a questionnaire was filled out for each individual. blood specimens were collected for hbsag testing. prevalence of hbsag was 5.8% (95% ci 3....

One hundred seven Chinese patients with primary hepatocellular carcinoma (PHC) were compared with 107 hospital controls for the presence of hepatitis B surface antigen and smoking, drinking, and dietary habits. Eighty-two % of PHC cases were hepatitis B surface antigen positive compared to 18% of controls (relative risk, 21.3; 95% confidence limits, 10.1 and 45.9). Prior history of jaundice was...

The seroepidemiology of hepatitis B was studied in Kiribati (formerly the Gilbert Islands). Six hundred and two (98%) of the population studied showed evidence of current or previous infection. The prevalence of hepatitis B surface antigen was 31% (188/615) and of the e antigen was 9% (58/615). Infection was acquired early in life, and the prevalence of both antigens declined with age. The rate...

Asymptomatic hepatitis B infection is characterized as a type of hepatitis in which hepatitis B surface antigen is present in the patient's peripheral blood despite the absence of clinical symptoms. Previous studies have shown that a particular genotype may effect clinical manifestations of hepatitis B infection; hence, the aim of the current study was to determine the frequency of hepatitis B ...

Manufacturing new Hepatitis B virus vaccines, specifically by the use of nanoparticles, is of high global interest. In this paper, a new biocompatible and biodegradable structure of nano-sized hepatitis B virus’ surface antigen (HBsAg) was generated by conjugation with dendrimers, a low cost biodegradable and biocompatible polymer. The physicochemical properties of the conjugate were characteri...

BACKGROUND Hepatitis B virus infection is a very common cause of chronic liver disease worldwide. It is estimated that 3% of Iranians are chronically infected with hepatitis B virus. Current population-based studies on both rural and urban prevalence of hepatitis B virus infection in Iran are sparse with results that do not always agree. We performed this study to find the prevalence of hepatit...
