Abstract

Evaluating the performance of well child clinics on adherence to recommended perinatal hepatitis B prevention programmes as well as assessing the outcome of infants living with hepatitis B surface antigen (HBsAg)-positive parents is important. A retrospective study was performed of 336 babies who had at least one HBsAg-positive parent and were followed-up in the well child clinic of Gazi University Hospital (Ankara, Turkey) between 2001 and 2009. Rates of passive immunisation in 109 babies with HBsAg-positive mothers and initiation of hepatitis B vaccination of all 336 babies with HBsAg-positive parents were 98.8% and 100% respectively. Ninety-two babies (27.4%) were lost to follow-up before completing primary immunisation. The recommended perinatal hepatitis B prevention programme was performed successfully in 194 of the 306 infants who were old enough for post-vaccination serotesting (63.4%). One baby became HBsAg-positive, and 88.1% of babies were seroprotected. Hepatitis B surface antibody (anti-HBs) levels were found to be increased if the HBsAg-positive parent was the father. There was a negative correlation between serotesting time and anti-HBs titres. The study infants had a total of 187 siblings and 123 (65.8%) were serotested after completing primary immunisation with 108 found to be seropositive. Although the vaccination rate in the perinatal hepatitis B prevention programme is satisfactory, post-vaccination serotesting and evaluation of infants and their siblings are still deficient.
