Two billion people around the world are exposed to the hepatitis B virus (HBV) and about 350 million are infected with chronic HBV. The infection can be acquired early (neonatal) and becomes chronic in 90%; this rate reduces to 30% between ages one and five years. There is a 25% risk of chronicity in adults. Nowadays, immunomodulatory and antiviral pegylated-interferons or oral antiviral agents are used in the treatment of chronic hepatitis B. Lamivudine is an effective oral antiviral agent which inhibits the replication of HVB by blocking reverse transcriptase enzyme. The study aims to detect the resistance of HBV to lamivudine in the community and evaluate the effectiveness and suitability of early treatment with lamivudine. ⋯ Hepatitis B virus in our region is not a lamivudine-resistant strain and early treatment with lamivudine is an effective and convenient method.
