OBJECTIVE: HIV prevention and treatment studies demonstrate that pharmacologic adherence metrics are more accurate than self-report. Currently-available metrics use liquid-chromatography/tandem-mass-spectrometry (LC-MS/MS), which is expensive and laboratory-based. We developed a specific and sensitive antibody against tenofovir, the backbone of treatment and prevention, but conversion to a lateral flow assay (LFA) -analogous to a urine pregnancy test- is required for point-of-care testing...

BACKGROUND: Intensified viral load (VL) monitoring for pregnant and breastfeeding women has been proposed to help address concerns around antiretroviral therapy (ART) adherence, viraemia and transmission risk, but there have been no systematic evaluations of existing policies. METHODS: We used an individual Monte Carlo simulation to describe longitudinal ART adherence and VL from conception until two years postpartum. We applied national and international guidelines for VL monitoring to the simulated data...

BACKGROUND: The HIV epidemic continues to grow among MSM in countries across sub-Saharan Africa including Nigeria. To inform prevention efforts, we used a phylogenetic cluster method to characterize HIV genetic clusters and factors associated with cluster formation among MSM living with HIV in Nigeria. METHODS: We analyzed HIV-1 pol sequences from 417 MSM living with HIV enrolled in the TRUST/RV368 cohort between 2013 and 2017 in Abuja and Lagos, Nigeria. A genetically linked cluster was defined among participants whose sequences had pairwise genetic distance of 1...

OBJECTIVE: We evaluated frequencies of T cells with high PD-1 expression (PD-1) before and after long-term effective antiretroviral therapy (ART), and determined if frequencies on-ART correlated positively with measures of HIV persistence and negatively with HIV-specific responses. METHODS: We enrolled individuals who started ART during chronic infection and had durable suppression of viremia for ≥4 years (N = 99). We assessed PD-1 T cell frequencies at timepoints pre- and on-ART using flow cytometry, and evaluated how frequencies on-ART are associated with measures of HIV persistence, HIV-specific immune responses, and immune activation levels...

OBJECTIVE: CD4CD19 conjugates play an important role in regulating antibody responses and follicular helper T cells development in animal models. However, little is known regarding the characteristic of CD4CD19 conjugates in humans with chronic HIV-1 infection. METHODS: The numbers of CD4CD19 conjugates were counted in 86 HIV-1-infected patients, including 66 typical progressors (TPs) and 20 complete responders (CRs). CD4CD19 conjugates were sorted by flow cytometry and dissociated into CD4 T singlets and CD19 B singlets...

OBJECTIVES: Immediate ART (or early access to ART for all, EAAA) is becoming a national policy in many countries in sub-Saharan Africa. It is plausible that the switch from delayed to immediate ART could either increase or decrease patient satisfaction with treatment. A decrease in patient satisfaction would likely have detrimental consequences for long-term retention and adherence, in addition to the value lost because of the worsening patient experience. We conducted a pragmatic stepped-wedge cluster-randomized controlled trial (SW-cRCT) to determine the causal impact of immediate treatment for HIV on patient satisfaction...

OBJECTIVES: CR2 is the main receptor for complement protein C3 and plays an important role in adaptive immune responses. CR2 genetic variants are associated with susceptibility to systemic lupus erythematosus as well as to HIV-1 infection. Additionally, CR2 function can be subverted by HIV-1 for an efficient entry into target cells; in a process known as antibody-dependent enhancement of viral infection. We sought to determine the association between CR2 gene variants with HIV-1 acquisition after vaccination with recombinant gp120 protein (Vax004 clinical trial)...
