OBJECTIVE: SMS can collect adherence data on a frequent basis and is relatively anonymous, and therefore could potentially reduce recall and social desirability biases prevalent in other self-reported measures. METHODS: We compared SMS self-reported adherence to three self-reported adherence questions (rating of ability to adhere, frequency of doses taken, percentage of doses taken) and two objective adherence measures (electronic adherence monitoring [EAM] and plasma tenofovir levels) using data from HIV-uninfected members of serodiscordant couples enrolled in a pre-exposure prophylaxis demonstration project in Kenya and Uganda...

OBJECTIVES: Possible effects of HIV on thyroid function in the modern combination antiretroviral therapy (cART) era are largely unknown. We aimed to investigate the prevalence and associated risk factors of thyroid dysfunction in well treated people living with HIV (PLWH) and matched uninfected controls and to examine whether HIV is independently associated with thyroid dysfunction. DESIGN AND METHODS: Thyroid stimulating hormone (TSH), free thyroxine, total thyroxine and free triiodothyronine were measured in 826 PLWH from the Copenhagen co-morbidity in HIV infection (COCOMO) Study and in 2,503 matched uninfected controls, and medical treatment for hypo- or hyperthyroidism was recorded...

OBJECTIVES: This study investigated whether Env-mediated fusion levels of R5X4 viruses are associated with long-term survival of an infected CCR5-/- patient. DESIGN: Four R5X4 Envs were cloned from each of two infected homosexual individuals (DR and C2) homozygous for the CCR5Δ32 allele. DR is a long-term survivor chronically infected with HIV-1 and his Envs were cloned 12 years after testing HIV+, while C2 Envs were isolated 1 year after primary infection. METHODS: The current study sequenced the gp41 subunits and created hybrid Envs that contained exchanged gp41 subunits or V3 loops...

OBJECTIVES: Women likely require higher adherence than men to pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) for similar efficacy. Pharmacologic metrics of adherence predict efficacy better than self-report, but expected drug levels (adherence benchmarks) must be established using directly-observed therapy. We sought to evaluate whether tenofovir hair concentrations differ between women and men receiving directly-observed TDF/FTC. METHODS: We assessed tenofovir hair concentrations in HIV-uninfected volunteers randomized to receive 100%, 67%, or 33% of daily dosing of TDF/FTC for 12 weeks (DOT-DBS, NCT02022657)...

OBJECTIVES: Studies examining engagement in HIV care often capture cross-sectional patient status to estimate retention and identify predictors of attrition, which ignore longitudinal patient care-seeking behaviors. We describe the cyclical nature of (dis)engagement and re-entry into HIV care using the state transition framework. DESIGN: We represent the dynamic patterns of patient care-retention using five states: Engaged in care, missed 1, 2, 3 or more expected visits, and deceased...

BACKGROUND: Interleukin-21 (IL-21) modulates HIV-1 infection through the elicitation of different antiviral mechanisms, including Th17 lineage commitment and induction of microRNA (miR)-29, a miRNA endowed with anti-HIV activity. As miR-29 expression is significantly increased in HIV-1-exposed seronegative individuals (HESN), we investigated the role of miR-29/IL21 axis in the natural control of HIV-1 infection. METHODS: PBMCs isolated from 15 Italian sexually-exposed HESN and 15 HIV-unexposed healthy controls (HC) were in vitro infected with an R5-tropic HIV-1Ba-L strain...

INTRODUCTION: HIV-tuberculosis (TB) co-infection remains an important cause of mortality in sub-Saharan Africa. Clinical trials have reported early (within 2 weeks of TB therapy) antiretroviral therapy (ART) reduces mortality among HIV-TB co-infected research participants with low CD4 counts, but this has not been consistently observed. We aimed to evaluate the current WHO recommendations for ART in HIV-TB co-infected patients on mortality in routine clinical settings. METHODS: We compared two cohorts before (2008-2010) and after (2012-2013) policy change on ART timing after TB and examined the effectiveness of early versus delayed ART on mortality in HIV-TB co-infected participants with CD4 100 cells/μl or less...

BACKGROUND: HIV-associated atherosclerosis is a major co-morbidity due in part to systemic effects of the virus on cholesterol metabolism. HIV protein Nef plays important role in this pathology by impairing maturation of the main cellular cholesterol transporter, ABCA1. ABCA1 maturation critically depends on calnexin, an integral endoplasmic reticulum membrane chaperone, and Nef binds to the cytoplasmic domain of calnexin and impairs interaction of calnexin with ABCA1. Overarching goal of the present study was to model Nef-calnexin interaction interface, and identify small molecule compounds potentially inhibiting this interaction...
