Furthermore, the emergence of HBV polymerase gene variants in YMDD motif during therapy was examined. Additionally, the most commonly occurring type of mutation in the polymerase YMDD region were investigated. The study involved 27 HBeAg positive children with chronic hepatitis B. Children included to lamivudine therapy were previously treated without effects with interferon alpha. %U http://czasopisma.viamedica.pl/fhc/article/view/4226
