However, their effect in healthy adults remains unknown. We aimed to analyze the impact of tenofovir disoproxil fumarate plus emtricitabine (TDF\/FTC)\u2013based preexposure prophylaxis (PrEP) on mitochondria of subjects at high risk of human immunodeficiency virus type 1 infection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was an observational, prospective study of 59 healthy adults enrolled in the PrEP program at Virgen del Roc\u00edo University Hospital. Mitochondrial DNA and common deletion 4977 were measured using digital droplet polymerase chain reaction. Mitochondrial density, membrane potential, oxidative stress, metabolic profile, and morphology were assessed by flow cytometry, real-time cellular bioenergetics measurements, and transmission electron microscopy, respectively, at baseline and after 12 months. Values were compared by the Wilcoxon test, and correlations between variables were assessed using the Spearman rank correlation coefficient (\u03c1).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our results showed that after 12 months, TDF\/FTC induced a mitochondrial oxidative stress increase in myeloid and lymphoid populations. Mitochondrial density decreased in CD8+ T cells and natural killer cells, while mitochondrial membrane potential was augmented in all lymphoid populations. Cell bioenergetic health was compromised, evidenced by reduced oxygen consumption rate, declined adenosine triphosphate production, and impaired response capacity to an energetic demand. Changes in the shape, membrane integrity, cristae structure, size, and distribution of the mitochondria throughout the cytoplasm were also observed. All participants experienced alterations in 1 or more measured parameters.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
