We studied the relationship between viral diversity and susceptibility to broadly neutralizing antibodies (bNAbs) in longitudinal plasma and peripheral blood mononuclear cells from 89 people with HIV who initiated antiretroviral therapy (ART) during acute and early HIV-1 infection (AEHI). HIV-1 diversity and predicted bNAb susceptibility were comparable across AEHI. Diversity evolution was not observed during ART, suggesting (pro)viruses at initiation or during treatment may identify individuals with susceptible virus for bNAb interventional trials...

OBJECTIVE: Bone loss in people with HIV (PWH) is poorly understood. Switching tenofovir disoproxil fumarate (TDF) to tenofovir alafenamide (TAF) has yielded bone mineral density (BMD) increases. PETRAM (NCT#:03405012) investigated whether BMD and bone turnover changes correlate. DESIGN: Open-label, randomized controlled trial. SETTING: Single-site, outpatient, secondary care. PARTICIPANTS: Nonosteoporotic, virologically suppressed, cis-male PWH taking TDF/emtricitabine (FTC)/rilpivirine (RPV) for more than 24 weeks...

Injectable cabotegravir and rilpivirine long-acting therapy is a revolutionary new antiretroviral treatment (ART) option for HIV infection in virologically suppressed adults on a stable ART. The aim of this study from SCOLTA multicenter observational prospective database is to describe the first people living with HIV (PWH) who started this regimen in Italy, assessing adherence to eligibility criteria, describing clinical-epidemiological characteristics compared to registration trials-population and describe early treatment-discontinuations...

The available knowledge regarding classification, nomenclature, and reference sequence selection for the various sub-subtypes of circulating recombinant forms (CRFs) is inadequate to fulfill the growing demands of research focused on HIV prevention. We analyzed the spread of CRF01_AE and CRF07_BC strains, mainly in China, to complement and update the existing nomenclature and to propose a reference sequence selection criteria for sub-subtypes of CRFs.

In sub-Saharan Africa (SSA), MSM - a high HIV prevalence group - experience strong social stigma and pressure to have female partners. Accordingly, they could constitute a bridging group for HIV transmission to cisgender women. We developed a multilevel summary of MSM sexual behaviors and risk with women in various SSA regions. Following PRISMA guidelines, we conducted a mixed-method systematic review of data of sex with women in MSM in SSA. We performed meta-analyses on quantitative data (i.e. percent of recent sex and condomless sex with women) for each SSA region (when proportions reported in ≥4 studies)...

OBJECTIVE: HIV-1 invades the brain within days post-transmission. This study quantitated cerebrospinal fluid (CSF) white blood cell count (WBC) and investigated whether it associated with plasma and CSF HIV-1 RNA during untreated acute HIV infection (AHI). DESIGN: Seventy participants underwent lumbar puncture during Fiebig stages I-V AHI. METHOD: WBC and HIV-1 RNA with a lower limit of quantification (LLQ) of 80 copies/ml were measured in CSF...

BACKGROUND: Combination antiretroviral therapy (cART) may reduce cancer risk among people with HIV (PWH), but cancer-specific associations are incompletely understood. METHODS: We linked HIV and cancer registries in Texas to a national prescription claims database. cART use was quantified as the proportion of days covered (PDC). Cox proportional hazards models assessed associations of cancer risk with cART usage, adjusting for demographic characteristics, AIDS status, and time since HIV report...

INTRODUCTION: HIV preexposure prophylaxis (PrEP) is highly effective at preventing HIV. We aimed to assess mental and physical health among long-term PrEP users in Australia's X-PLORE cohort. METHODS: In early 2021, 1485 X-PLORE participants were emailed a survey covering demographics, sexual practices, ongoing PrEP use, physical and psychological diagnoses received since commencing PrEP, substance use, and impacts of the COVID-19 pandemic. Current anxiety and depression were assessed using GAD-7 and PHQ-9 questionnaires...

Obesity incidence is increasing among people with HIV. Doravirine is a recommended first-line antiretroviral drug in many countries with no data from people with obesity. This study investigates the exposure of doravirine 100 mg standard dose in obese versus normal weight patients using clinical data combined with physiologically based pharmacokinetic modelling. Results from both approaches showed an elevated doravirine exposure during obesity, yet within the safety range of doravirine with no need for dose modification...
