Abstract

Objective: To analyze the efficacy and tolerability of the strategy to change from rilpivirine (RPV) based regimens to bictegravir / emtricitabine / tenofovir alafenamide (B/F/TAF).

Methods: Single-center, observational and retrospective study. Patients who made the change to B/F/TAF before February 2020 were selected, analyzing the results after 24 and 48 weeks. The percentage that remained with an undetectable viral load was determined, as well as the changes in CD4 + lymphocytes, metabolic parameters and renal function.

Results: A total of 42 patients were included. Thirty-two of the 35 patients (91.4%) who completed the 48 weeks of follow-up had an undetectable viral load. The CD4 + lymphocyte count remained stable at 24 and 48 weeks. The response to B/F/TAF was not influenced by the two analogs previously received.

Conclusions: Switching from triple therapy with RPV to B/F/TAF is a safe and effective strategy in real life.

Objetivo: Analizar la eficacia y tolerabilidad de la estrategia de cambio desde regímenes basados en rilpivirina (RPV) a bictegravir/emtricitabina/tenofovir alafenamida (B/F/TAF) en la vida real.

Métodos: Estudio unicéntrico, observacional y retrospectivo. Se seleccionaron pacientes que cambiaron de un régimen con RPV a B/F/TAF antes de febrero del 2020 analizándose los resultados después de 24 y 48 semanas. Se determinó el porcentaje que permanecía con carga viral indetectable, así como los cambios en linfocitos CD4+, parámetros metabólicos y función renal.

Resultados: Se incluyeron en el estudio 42 pacientes. 32 de los 35 (91,4%) que completaron las 48 semanas de seguimiento tenían carga viral indetectable. El recuento de linfocitos CD4+ permaneció estable a las 24 y a las 48 semanas. El tipo de análogos recibidos previamente no influyó en la respuesta

Conclusión: El cambio desde una triple terapia con RPV a B/F/TAF es una estrategia segura y eficaz en la vida real.
