Changes in behavioral self reported outcomes in a cohort of patients with primary HIV infection (eLibrary) - Sep 18, 2021 - Abstract #EACS2021EACS_373; In this cohort of PLWH at high risk of HIV transmission, the initiation of care and start of ART decreased the need to disclose HIV status to sexual partner, without substantial changes in engaging in risky sexual behaviour. This finding strongly suggests the need to achieve viral suppression as quickly as possible and to adopt, especially in the first year after starting ART, targeted behavioural and biomedical prevention strategies.

A retrospective cohort study (eLibrary) - Sep 18, 2021 - Abstract #EACS2021EACS_204; We included all patients co-infected with HIV and tuberculosis starting a rifampicin-based regimen, with a plasma viral load (VL)>1000 copies/mL. In this retrospective study, raltegravir and dolutegravir yielded similar efficacy and safety results to efavirenz for the treatment of patients co-infected with HIV and TB.

A consistent ART utilization pattern was observed across comorbidity subpopulations of PLWH. Given the potential for drug-condition interactions with ART, an individualized approach to care based on clinical characteristics could minimize the risk of adverse events and exacerbation of pre-existing conditions.

Subgroup efficacy analyses of long-acting subcutaneous lenacapavir in phase 2/3 in heavily treatment-experienced people with HIV (CAPELLA study) (eLibrary) - Sep 18, 2021 - Abstract #EACS2021EACS_140; Purpose: Lenacapavir (LEN), a potent first-in-class inhibitor of HIV-1 capsid function, is in development as a long-acting agent for treatment and prevention of HIV-1. In the ongoing Phase 2/3 study (CAPELLA) in heavily treatment-experienced (HTE) people with HIV-1 (PWH) with multidrug-resistance with ongoing viremia (≥ 400 copies/mL) (Figure), LEN demonstrated potent antiviral activity during the functional monotherapy period (1.9 log decline) and led to high rates of virologic suppression in combination with an optimized background regimen (OBR) at Week 26 (81%).

In our cohort of ART-experienced patients, DTG-based DT was offered to patients with a long cART-exposure with good tolerance and a high probability of virological success also in patients with RT-mutations at cumulative genotype; no significant modifications in CD8 activated T-cells and plasma lipids were observed.

Journal: Mechanistic Analysis of the Broad Antiretroviral Resistance Conferred by HIV-1 Envelope Glycoprotein Mutations. (Pubmed Central) - Sep 9, 2021 We previously reported that, in vitro, the lab-adapted HIV-1 NL4-3 strain can acquire resistance to the integrase inhibitor dolutegravir (DTG) by acquiring mutations in the envelope glycoprotein (Env) that enhance viral cell-cell transmission...We observed that many Env mutations accumulated in individuals failing integrase inhibitor therapy despite a low frequency of resistance mutations in integrase. Our findings suggest that broad-based Env-mediated drug resistance may impact therapeutic strategies and provide clues toward understanding how ARV-treated individuals fail therapy without acquiring mutations in drug target genes.

Clinical, Journal: Structural effects of HIV-1 subtype C integrase mutations on the activity of integrase strand transfer inhibitors in South African patients. (Pubmed Central) - Sep 8, 2021 Molecular modeling and docking showed that RAMs and polymorphisms associated with INSTI-based therapy affect protein stability and this is supported by their weakened hydrogen-bond interactions compared to the wild-type. To the best of our knowledge, this is the first study to identify a double mutant in the 140's loop region from South African HIV-1C isolates and study its effects on Raltegravir, Elvitegravir, and Dolutegravir binding.Communicated by Ramaswamy H.
