Abstract: Objective To observe the changes of mitochondrial DNA levels in peripheral blood monouclear cells in patients with chronic hepatitis B receiving long-term adefovir treatment.Methods Patients with CHB were divided into three groups:(1) 2 years group(n=18):receiving adefovir for 2 years;(2)3 years group(n=25):adefovir for 3 years;and (3) control group(n=22):naive patients without antiviral treatment.The mtDNA of PBMCs were detected by quantitative real-time PCR. Plasma MDA and F2-isoprostanes were measured by ELISA and TAOC were detected by spectrophotometry.Results The mtDNA in PBMCs in the 2-year treatment group was 0.6±0.4 copies/cell and in the 3-year treatment group was 0.8±0.5 copies/cell,both significantly lower than in the control group(1.4±1.2copies/cell,P<0.05);the F2-isoprostanes in 2-year treatment group was 1.5±0.8 ng/ml and in 3-year treatment group was 2.2±1.3ng/ml,much lower than that in the control group(3.7±2.7 ng/ml,P<0.05);the TAOC in 2-year treatment group was 3.0±1.1 IU/ml,and in 3-year treatment group was 2.3±1.4IU/ml, significantly lower than in the control group(4.3±1.8 IU/ml,P<0.05).Conclusion The long-term administration of adefovir might injure mitochondrial DNA.
