Introduction: Viral hepatitis is one of the causes of premature death in world peoples, according to WHO reports, five percentage of people are carrier, lethal from this disease is 1%, therefore about 1-1.5 million people each year die from complications of this disease. This disease varies from an acute to chronic illness. The aim of this study was to determine the level of anti-HBs Ag (hepati...

BACKGROUND Neonatal immunization with hepatitis B (HB) vaccine induces protective levels of antibody (anti-HBs > or =10 IU/L) in a majority of vaccines. However, the duration of protection after HB vaccination in infants is unknown. A smaller proportion of children vaccinated beginning at birth with three doses of HB vaccine were found to have protective titers 5-10 years after initial vaccinat...

Four hundred and fifty three healthy children immunized with a course of hepatitis B vaccine beginning at birth were tested at 10-11 years of age for persistence of anti-hepatitis B-S antigen antibody (anti-HBs); and responses of children without protective antibody to different doses of hepatitis B vaccine booster were evaluated. Although nearly 42% of them were not seroprotected, but most of ...

The prevalence of both the hepatitis-B surface antigen (HBsAg) and its specific antibody (anti-HBs) was significantly greater in the sera of White patients suffering from sexually transmitted diseases than that in White blood donors. However, Black patients with venereal diseases did not show an increased prevalence of either HBsAg or anti-HBs. These findings support the view that heterosexual ...

Patients undergoing treatment at a community-based renal dialysis clinic were monitored monthly for hepatitis B surface antigen (HBsAg) and antibody to HBsAg (anti-HBs). Of 160 patients who began treatment HBsAg(-)/anti-HBs(-), 77 subsequently became HBsAg(+). Once HBsAg(+), males were more likely to remain HBsAg(+) indefinitely, whereas females were more likely to convert to HBsAg(-) and devel...

Materials and Methods: The study population consisted of 147,200 healthy schoolchildren between 6 to 17 years of age living in the Mardin area. A total of 802 children were randomly selected by systematic sampling method. Hepatitis B surface antigen (HBsAg), antibody to HBsAg (anti-HBs), and antibody to hepatitis B core antigen (anti-HBc) were analyzed in blood samples by enzyme-linked immunoso...

To evaluate the relationships between human T lymphotropic virus type I (HTLV-I) and hepatitis virus type B (HBV) infections, we compared both individual and geographical distributions of carriers of HTLV-I and HBV, and antibody positives to HBV in two ATL-endemic islands in Kyushu, Japan. The positive rates of antibodies to HTLV-I (anti-HTLV-I-Ab) in sera among healthy inhabitants older than 3...

The prevalence of hepatitis B surface antigen (HBSAg) and antibody (anti-HBS) was determined in 531 white and 519 black diabetic outpatients and in appropriate white and black control populations. There was no difference between the prevalence of either HBSAg or anti-HBS in either the white or black diabetics and that in the white and black controls. These findings make it unlikely that the vas...
