Background: Mitochondrial consequences from foetal exposure to HIV infection and antiretrovirals could be further investigated.Objective: The main objective of this study was to evaluate maternofoetal mitochondrial disturbances in HIV infection and antiretroviral administration in human pregnancies as the aetiopathogenic basis of suboptimal perinatal-clinical features.Design: Cross-sectional, prospective, observational, exploratory and controlled study.Methods: Clinical/epidemiological data of 35 HIV-infected pregnant women and 17 controls were collected. Mitochondrial DNA (mtDNA) and RNA (mtRNA) content (real time-PCR), enzymatic activities and content (spectrophotometry) were measured in leucocytes. Genetic-functional, maternofoetal and molecular-clinical correlations were assessed.Results: Birth weight was lower in infants from HIV-infected mothers compared with controls. MtDNA values were slightly decreased in HIV cases, although not reaching statistical significance. MtRNA values were lower in HIV-infected mothers. Similarly, binary complex II+III enzymatic activity decreased to 50% in both HIV-infected mothers (44.45 +/- 3.77%) and their infants (48.79 +/- 3.41%) (P = 0.001 and P < 0.001). Global CI+III+IV enzymatic activity was lower in HIV-infected mothers and infants (90.43 +/- 2.39% and 51.16 +/- 9.30%) (P < 0.005 and P < 0.05). MtDNA content correlated with function in mothers and infants. Maternofoetal parameters correlated at genetic and functional levels.Conclusion: HAART toxicity caused mitochondrial damage in HIV-infected pregnant women and their newborns, being present at a genetic and functional level with a maternofoetal correlation.
