Determination of Hepatitis B Surface Antibody Titer in Vaccinated Children with Major Thalassemia in Kerman-Iran
Authors
Abstract:
Background: Thalassemia patients are more susceptible to hepatitis than the normal population due to the frequent blood transfusions. Objective: To determine the immune response of children with major ß-thalassemia, by measuring anti-hepatitis B surface antibody (anti-HBs Ab) following the last HBV vaccine injection. Methods: This study was carried out on 215 thalassemic children who received three standard intramuscular recombinant HBV vaccines. Children age ranged between 1-4.5 with a mean age of 3.37 years. Based on the time lapsed since last vaccine injection, the subjects were divided into three groups; 0-15 months, 15-30 months and 30-45 months, respectively. Based on the serum levels of anti-HBs antibody, subjects were categorized as: good responders (anti-HBs >100 IU/Lit), low responders (anti-HBs 10-100 IU/Lit) and non-responders (anti-HBs

OBJECTIVE Hepatitis C virus (HCV) is an etiological agent responsible for occurrence of post-transfusion hepatitis in thalassemic patients. This study identified hepatitis C genotypes in pediatric and adolescent thalassemic patients and their correlation with age, blood transfusion, HCV RNA viral titer and liver function. METHODS This study considers cross-sectional data from the Center for T...
full textPersistence of antibody to hepatitis B surface antigen among vaccinated children in a low hepatitis B virus endemic area.
BACKGROUND A potential problem of hepatitis B immunization is that vaccine-induced antibody to hepatitis B surface antigen (anti-HBs) declines to low levels with age. This study investigated the persistence of anti-HBs in vaccinated children in a low hepatitis B virus (HBV) endemic area. METHODS Plasma samples of 938 children between ages of 8 months and 15 years were tested for the presence ...
