The most common side-effect is gastrointestinal (GI) distress which may be associated with changes in the microbiome. Dysbiosis of the microbiome can have numerous health-related consequences. To understand the effect of PrEP on dysbiosis, we evaluated 27 individuals; 14 were taking PrEP for an average of 171 weeks. Sequencing of 16S rRNA was performed using self-collected rectal swabs. Mixed beta diversity testing demonstrated significant differences between PrEP and non-PrEP users with Bray–Curtis and unweighted UniFrac analyses (p = 0.05 and 0.049, respectively). At the genus level, there was a significant reduction in Finegoldia, along with a significant increase in Catenibacterium and Prevotella in PrEP users. Prevotella has been associated with inflammatory pathways, insulin resistance and cardiovascular disease, while Catenibacterium has been associated with morbid obesity and metabolic syndrome. Overall, these results suggest that PrEP may be associated with some degree of microbiome dysbiosis, which may contribute to GI symptoms. Long-term impact of these changes is unknown. Resumen: Los regímenes basados en tenofovir como profilaxis previa a la exposición (PPrE) son muy eficaces en prevenir la infección por VIH. El efecto secundario más común es el malestar gastrointestinal (GI) que puede estar asociado con cambios en el microbioma. La disbiosis del microbioma puede tener numerosas consecuencias relacionadas con la salud. Para comprender el efecto de la PPrE sobre la disbiosis, evaluamos a 27 individuos; 14 de los individuos tomaron PPrE durante un promedio de 171 semanas. La secuenciación del ARNr 16S se realizó utilizando hisopos rectales recolectados por los propios pacientes. Las pruebas beta de diversidad mixta demostraron diferencias significativas entre los usuarios de PPrE y los que no utilizaron PPrE al analizarlos mediente Bray–Curtis y UniFrac no ponderados (p = 0,05 y 0,049, respectivamente). A nivel de género, hubo una reducción significativa de Finegoldia, junto con un aumento significativo de Catenibacterium y Prevotella en usuarios de PPrE. Prevotella se ha asociado con trayectorias inflamatorias, resistencia a insulina y enfermedades cardiovasculares, mientras que Catenibacterium se ha asociado con enfermedades como obesidad mórbida y padecimientos de síndrome metabólico. En general, estos resultados sugieren que la PPrE puede estar asociada con cierto grado de disbiosis del microbioma, lo que puede contribuir a los síntomas gastrointestinales. El impacto a largo plazo de estos cambios se desconoce. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
