Change in metabolic parameters after switching from triple regimens with tenofovir alafenamide to dolutegravir-based dual therapy. Bi-lipid study.

Introduction: The use of tenofovir alafenamide (TAF) has been associated with increased cholesterol and body weight. Real-life data on the metabolic effects of switching from a TAF-based triple regimen to a dolutegravir (DTG)-based two-drug regimen (2-DR) are scarce.

Methods: A retrospective cohort study of patients who have switched from a triple TAF-based regimen to a 2-DR [DTG-lamivudine (DTG-3TC) or DTG- rilpivirine (DTG-RPV]) with at least 6 months of follow-up.

Changes in Quality of Sleep, Mood, and Other Neuropsychiatric Symptoms After Switching Dolutegravir/Lamivudine/Abacavir to Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide in a Randomized Study of People With Human Immunodeficiency Virus With Poor Sleep Quality: GESIDA 10418.

Background: Although switching antiretroviral therapy (ART) in people with human immunodeficiency virus experiencing insomnia due to dolutegravir-related neurotoxicity is well founded upon evidence, there is a lack of proof in regard to the outcome of stopping dolutegravir-based ART in people without insomnia but reporting poor sleep quality.

Methods: This is a randomized, multicenter, open-label study to evaluate the reversibility of patient-reported sleep disturbances in patients on dolutegravir/lamivudine/abacavir without insomnia after switching to darunavir/cobicistat/emtricitabine/tenofovir alafenamide. The participants were randomized to switch ART at baseline or at week 4 and then completed 8 weeks of darunavir/cobicistat/emtricitabine/tenofovir alafenamide.
