Amerikan Pediatri Akademisi asilama sonrasi anti-HBs olusup olusmadigini saptamak icin rutin testler in gerekli olmadigini belirtmektedir, fakat asagida sayilan ozel gruplar icin ucuncu asi dozundan 1 veya 2 ay sonra antikor titresi kontrolunu onermektedir: (2) hemodiyaliz hastalari; (3) HIV enfeksiyonu olanlar; (4) kesici yaralanmalar icin mesleki riski olanlar; (5) HBV ile karsilasma riski olan immun yetmezligi olan hastalar; (6) HBsAg pozitif hastalarla duzenli cinsel temasi olan insanlar.
What was notable was that the patient presented a dramatic decrease in HBV-DNA, down to 227 IU/mL which, however, was not associated with clearance of HBsAg or HBeAg or with development of antibodies.
6) To eliminate the risk of perinatal transmission of HBsAg from mothers to their infants; a program of combined active and passive immunization has been established.
This was characterized by continued reduction of multiple HBV viral markers, including HBsAg, and coinciding with an increase in circulation of liver enzyme alanine aminotransferase, indicative of host response.
While there is no clinical cure for chronic HBV infection, a functional cure can be achieved, and this is defined as the suppression or elimination of HBV DNA with HBsAg loss and appearance of antibodies to HBsAg.
