SummaryObjectivesDetermine if a nucleoside reverse transcriptase inhibitors (NRTI)-free regimen affected mitochondrial DNA (mtDNA) levels in peripheral blood mononuclear cells (PBMCs) of patients enrolled in BIKS-2 trial.MethodsAntiretroviral (ARV) naïve (N = 13) and NRTI experienced (N = 7) patients, received lopinavir/ritonavir, a boosted protease inhibitor, and efavirenz, a non-nucleoside reverse transcriptase inhibitor from Month (M) 0 to M12 (1-year BIKS trial) and from M12 to M36 (2-year BIKS-2 trial). MtDNA was quantified at M12, M24 and M36 via real-time PCR assay.ResultsFrom M12 to M36, the 20 patients have maintained undetectable plasma HIV-1 RNA, gained CD4 cells and had no side effects attributable to these drugs. Median mtDNA contents were constant: 478.6 at M12, 478.6 at M24 and 324.4 copies/cell at M36 (pM12-M36 = 0.5). Because M0 data is missing, these results were compared to those of two groups of age matched individuals: healthy donors and HIV-infected patients before and after exposure to NRTIs. Healthy donors have higher contents (871), followed by patients never treated (602), than by BIKS patients where 7 had toxic NRTIs (478.6) and at last by patients exposed for six months to the most toxic combination (ddI-d4T) (85 copies/cell).ConclusionLopinavir/ritonavir + efavirenz did not affect mtDNA contents in PBMCs.
