Original Communication


Previous studies have shown that the antiviral nucleoside analogue zidovudine (AZT) depletes levels of mitochondrial DNA (mtDNA) in muscle of patients on long-term therapy. In this study we found that in a similar group of eight HIV-positive patients receiving AZT there was no depletion of brain mtDNA. This finding suggests that AZT related mtDNA depletion is not a contributing factor in the HIV encephalopathy that occurs in a proportion of HIV positive patients receiving this antiviral agent.
