Abstract Mitochondrial toxicity of nucleoside analogues has been proposed to be the etiology of a range of side-effects from antiretroviral therapy of HIV infection. In this study, urinary 8-hydroxy-2'-deoxyguanosine (8OH2'dG), a metabolite of oxidized DNA, was measured to determine if antiretroviral therapy leads to oxidative damage to DNA. A cross-sectional study was carried out measuring urinary 8OH2'dG in three groups of HIV-infected patients: (1) antiretroviral medication naïve, (2) patients on antiretroviral medications without lipodystrophy and (3) patients on antiretroviral medications with lipodystrophy. Twenty-five patients were enrolled in each group. The mean spot urinary 8OH2'dG measurements per mg creatinine for the three groups were: antiretroviral naïve 4.27 +/- 0.61 (ng 8OH2'dG/mg creatinine +/- SEM), on antiretroviral medications without lipodystrophy 2.88 +/- 0.26, and on antiretroviral medications with lipodystrophy 3.27 +/- 0.30. The differences between the means of the three groups is not statistically significant (p = 0.055), and these results are not significantly different from reported values for healthy controls [A carbon column-based liquid chromatography electrochemical approach to routine 8-hydroxy-2-deoxyguanosine measurements in urine and other biologic matrices: a one-year evaluation of methods.
