Motivation: Changing the course of the human immunodeficiency virus type I (HIV-1) pandemic is a high public health priority with approximately 39 million people currently living with HIV-1 (PLWH) and about 1.5 million new infections annually worldwide. Broadly neutralizing antibodies (bnAbs) typically target highly conserved sites on the HIV-1 envelope glycoproteins (Envs), which mediate viral entry, and block the infection of diverse HIV-1 strains. But different mechanisms of HIV-1 resistance to bnAbs prevent robust application of bnAbs for therapeutic and preventive interventions.
Results: Here we report the development of a new database that provides data and computational tools to aid the discovery of resistant features and may assist in analysis of HIV-1 resistance to bnAbs. Bioinformatic tools allow identification of specific patterns in Env sequences of resistant strains and development of strategies to elucidate the mechanisms of HIV-1 escape; comparison of resistant and sensitive HIV-1 strains for each bnAb; identification of resistance and sensitivity signatures associated with specific bnAbs or groups of bnAbs; and visualization of antibody pairs on cross-sensitivity plots. The database has been designed with a particular focus on user-friendly and interactive interface. Our database is a valuable resource for the scientific community and provides opportunities to investigate patterns of HIV-1 resistance and to develop new approaches aimed to overcome HIV-1 resistance to bnAbs.

The integration of nanotechnology into antiretroviral drug delivery systems presents a promising avenue to address challenges posed by long-term antiretroviral therapies (ARTs), including poor bioavailability, drug-induced toxicity, and resistance. These limitations impact the therapeutic effectiveness and quality of life for individuals living with HIV. Nanodrug delivery systems, particularly nanoemulsions, have demonstrated potential in improving drug solubility, enhancing bioavailability, and minimizing systemic toxicity.

Background: The S147G mutation is associated with high-level resistance to the integrase strand transfer inhibitor (INSTI) elvitegravir. In several poorly documented cases, it was also selected in patients on dolutegravir. Given the widespread use of dolutegravir, further studies of S147G are required.

Background: Real-world data showing the long-term effectiveness of long-acting injectable cabotegravir and rilpivirine are scarce. We assessed the effectiveness of cabotegravir and rilpivirine in all individuals who switched to cabotegravir and rilpivirine in the Netherlands.
Methods: We used data from the ATHENA cohort, an ongoing observational nationwide HIV cohort in the Netherlands.

Background: BICSTaR is a multi-national, observational cohort evaluating the effectiveness, safety, and patient-reported outcomes (PROs) in treatment-naïve (TN) and -experienced (TE) people with HIV-1 receiving bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in routine clinical care. We present the 12-month (M12) outcomes of the Italian BICSTaR cohort.
Methods: Participants initiating B/F/TAF in routine care were prospectively followed.
