Description Quantitative analysis of HBV-DNA is extensively used worldwide for monitoring of lamivudine therapy of Hepatitis B virus (HBV) infection. We have analyzed the quantity of HBV-DNA during lamivudine therapy and investigated the relationship of lamivudine resistance to mutation type. Ninety-one hepatitis B patients were enrolled in the study where Real Time Polymerase Chain Reaction (PCR) did estimation of HBV DNA and mutation was analyzed by sequence detection via PCR. HBV-DNA was detected in the serum of 96.7% (88/91) patients with mean viral load ranging from 1 ´ 105 to 1 ´ 109. More than 80% patients responded to and 17.3% patients showed resistance to lamivudine therapy. All lamivudine resistant patients had HBV YMDD mutation of either rtL180M/M204V or rtL180M/ M204I type. PCR based analysis of HBV DNA and sequence based mutation detection can be a practically feasible approach in Bangladesh to monitor hepatitis B patients under lamivudine therapy.
