Objectives: This study aimed to evaluate the effectiveness of bictegravir (BIC)-based antiretroviral therapy (ART) against HIV-1 sub-subtype A6 viruses carrying the L74I polymorphic mutation in integrase.
Methods: A total of 100 ART-naive people living with HIV from the Moscow Regional AIDS Center were enrolled between May and July 2023. HIV-1 subtypes and baseline drug resistance mutations were analysed prior to treatment initiation.

Background: Patients on second-line protease inhibitor-based regimens in low-income and middle-income countries have high rates of nucleoside reverse transcriptase inhibitor (NRTI) resistance, but access to testing is scarce. We aimed to assess the efficacy of combination oral bictegravir, emtricitabine, and tenofovir alafenamide in this population.
Methods: In this open-label non-inferiority trial conducted in Port-au-Prince, Haiti, adults (aged 18 years or older) with viral suppression (HIV-1 RNA <200 copies per mL) on second-line regimens including ritonavir-boosted protease inhibitors and two NRTIs were randomised (1:1) using a computer-generated random-number list.

(1) Background: Second-generation integrase strand transfer inhibitors (INSTIs) are now the preferred first-line therapies for human immunodeficiency virus (HIV). However, concerns regarding their side effects, such as weight gain and metabolic disturbances, have emerged. This scoping review aims to assess the effects of INSTIs on the gut microbiota, with a focus on differences between agents and their clinical implications.

Dolutegravir and bictegravir are second-generation HIV integrase strand transfer inhibitors (INSTIs) that were previously associated with abnormal weight gain. This monocentric cross-sectional study investigates associations between weight gain during the first year after initiation of dolutegravir, bictegravir or other anchor drugs and gut microbiome diversity as well as taxa composition. The study enrolled 79 participants receiving dolutegravir, 32 receiving bictegravir and 10 receiving non-INSTI based regimens.

Oral second-generation integrase strand transfer inhibitors are now anchor drugs of antiretroviral therapy (ART) globally due to their high resistance barriers. In high-income settings, guidelines recommend routine protease and reverse transcriptase resistance testing before ART initiation but suggest routine integrase resistance testing only for individuals at elevated risk of integrase resistance. Improved characterisation of transmitted integrase resistance, its detection, and its clinical impact will guide future recommendations for clinical decision making.
