During a two year period (2011 2012), a total of 1,596 consecutive serum samples from pregnant women were tested for the presence of HBsAg, anti-HCV and anti-HIV antibodies. HBsAg was detected in 11/1596 (0.7%; 95% CI = 0.34 1.23) tested women. All of them were HBeAg negative/anti-HBe positive. According to age, HBsAg prevalence was highest in the age group of less than 26 years (1.9%). In the ...

hepatitis b virus (hbv) infection and its sequelae such as cirrhosis and hepatocellular carcinoma has remained a serious public health problem throughout the world. the who strategy for effective control of hbv infection and its complications is mass vaccination of neonates and children within the framework of expanded programme on immunization (epi). vaccination with hepatitis b surface antige...

Warm antibody autoimmune haemolytic anaemia, a rare disease (0.2-1 per 100,000 populations), is due to the presence of warm agglutinins that react with protein antigens on the surface of red blood cells causing their premature destruction. Here, we present a case report of a 10 year old girl who came with features of haemolytic anaemia and history of blood transfusion since 3 years. On admissio...

OBJECTIVES This study aimed to evaluate the level of hepatitis B immunity among undergraduate students 23 years after commencement of the nationwide hepatitis B childhood immunization program in Malaysia. METHODS A total of 402 serum samples obtained from volunteer undergraduate students were screened for the presence of hepatitis B surface antibodies using qualitative ELISA. RESULTS Result...

Developing rapid, efficient, highly sensitive, simple, stable, and low-cost virus marker detection products that are appropriate for basic facilities is of great importance in the early diagnosis treatment viruses. Naked-eye methods especially important when medical testing limited. Polystyrene nanospheres (PSs) with catalytic specific recognition functions were successfully developed by simult...

Ninety-five health care workers and 91 controls were screened for seromarkers of both HBV (HBsAg, HBeAg, Anti-HBc) and HCV (anti-HCV) by ELISA. The control group showed a much higher frequency of seromarkers for both the viruses. HBsAg was positive in 5% of study group (health care personnel) and 14% of controls. Anti-HBc as a marker of past HBV-exposure was positive in 28% of study group as co...

Eight infants who developed HBsAg aged between 1 and 5 months were identified in the greater Copenhagen area during the period 1970--76. 7 had acquired the infection from their mothers and one had received a HBsAg-positive blood infusion, 3 infants had a transient infection lasting 2 to 8 months while the remaining cases developed persistent antigenaemia with evidence of minor liver dysfunction...

14 hepatitis B vaccine recipients who showed high titers of anti-hepatitis B surface antibodies in serum after booster immunization with a polyvalent hepatitis B surface antigen vaccine that contained trace amounts of hepatitis B virus (HBV) preS1 and preS2 envelope antigens were studied for their in vitro T cell response to these antigens. All 14 subjects displayed a significant proliferative ...
