HIV-1 superinfection, in which an infected individual acquires a second HIV-1 infection from a different partner, is one of the only settings in which HIV acquisition occurs in the context of a pre-existing immune response to natural HIV infection. There is evidence that initial infection provides some protection from superinfection, particularly after 6months of initial infection, when development of broad immunity occurs. Comparison of the immune response of superinfected individuals at the time of superinfection acquisition to that of individuals who remain singly infected despite continued exposure can shed light on immune correlates of HIV acquisition to inform prophylactic vaccine design...

Background: There is an increasing recognition of malnutrition among infants under 6 mo of age (U6M). Current diagnosis criteria use weight-for-length z scores (WLZs), but the 2006 WHO standards exclude infants shorter than 45 cm. In older children, midupper arm circumference (MUAC) predicts mortality better than does WLZ. Outcomes may also be influenced by exposure to HIV and size or gestational age at birth. Diagnostic thresholds for WLZ, MUAC, and other indexes have not been fully evaluated against mortality risk among U6M infants...

The release of World Health Organisation guidelines recommending the prophylactic use of daily Truvada(®) for all populations at high risk of acquiring HIV opens the way for implementation of oral pre-exposure prophylaxis (PrEP). The impact of new prevention technologies is, however, dependent on demand creation strategies such as user awareness, acceptability and access, which in turn are influenced by sociocultural and gender norms. This study was conducted in three locations in KwaZulu-Natal, urban, rural and peri-urban, with six participatory workshops...

INTRODUCTION: HIV-exposed, uninfected (HEU) infants are potentially at risk for cardiovascular disease due to in utero exposures. Feeding practices of the infant could compound this risk. However, few studies have evaluated dietary intake of HEU infants. We determined dietary factors associated with rapid weight gain (RWG) among HEU infants from birth to 6 months followed at the University of Miami HIV Screening Program. METHODS: In this cross-sectional analysis, logistic regression was used to determine dietary factors associated with RWG defined as a greater than 0...

Background: Newborns of HIV-infected mothers are given daily doses of nevirapine to prevent HIV-1 acquisition. Infants born to mothers with TB should also receive TB preventive therapy. TB preventive regimens include isoniazid for 6 months or rifampicin plus isoniazid for 3 months (RH preventive therapy). The effect of concomitant RH preventive therapy on nevirapine concentrations in infants is unknown. Patients and methods: Tshepiso was a prospective case-control cohort study of pregnant HIV-infected women with and without TB whose newborn infants received standard doses of nevirapine for HIV prophylaxis...

Background: Investigations into which HIV-1 sequence features may be selected for transmission during sexual exposure have been hampered by the small number of characterized transmission pairs in individual studies. Methods: To boost statistical power to detect differences in glycosylation, length, and electrical charge in the HIV-1 V1-V4 coding region, we re-analyzed all available 2,485 env sequences derived from 114 subjects representing 58 transmission pairs from previous studies using mixed effects linear regression and an approach to approximate the unobserved transmitted virus...

Landmark advances have been made in HIV/AIDS prevention and treatment. These include proof-of-concept and public health implementation of pre-exposure prophylaxis (PrEP) and "treatment as prevention" (TasP) to reduce HIV transmission as well as definitive evidence of the clinical gain from early antiretroviral treatment (ART) initiation. Significant progress has been made in understanding and addressing the social contexts and behavioral factors that impact HIV prevention, care, and treatment interventions...

INTRODUCTION: The efficacy of pre-exposure prophylaxis (PrEP) in preventing sexual acquisition of human immunodeficiency virus (HIV) is well established. Little is known about the feasibility of PrEP implementation in middle-income settings with concentrated epidemics among men who have sex with men (MSM) and transgender women (TGW). METHODS: PrEP Brasil is a prospective, multicentre, open-label demonstration project assessing PrEP delivery in the context of the Brazilian Public Health System...

Recent advances in biomedical HIV prevention have led to optimistic projections of a dramatic worldwide reduction of new infections by 2030. This optimism is counterbalanced by concerns that the protective benefits of one such technology, HIV pre-exposure prophylaxis (PrEP), may be negated by increases in other behaviours that offset these benefits (risk compensation). To contribute to a deeper understanding of concepts of safety and risk in the context of HIV PrEP, we draw on the narrative accounts of 61 male PrEP users who participated in the inaugural PrEP demonstration project: the iPrEx open-label extension study...

RATIONALE: Understanding mechanisms of resistance to M. tuberculosis (M.tb) infection in humans could identify novel therapeutic strategies as it has for other infectious diseases, such as HIV. OBJECTIVES: To compare the early transcriptional response of M.tb-infected monocytes between Ugandan household contacts of tuberculosis patients who demonstrate clinical resistance to M.tb infection (cases) and matched controls with latent tuberculosis infection. METHODS: Cases (n = 10) and controls (n = 18) were selected from a long-term household contact study in which cases did not convert their tuberculin skin test (TST) or develop tuberculosis over two years of follow up...

Despite the demonstrated effectiveness of HIV pre-exposure prophylaxis (PrEP) and evidence that most PrEP users do not engage in risk compensation (i.e., increased risk behavior due to a perceived decrease in HIV susceptibility), some healthcare providers report patient risk compensation to be a deterrent to prescribing PrEP. Overcoming this barrier is essential to supporting PrEP access and uptake among people at risk for HIV. To inform such efforts, this qualitative study explored PrEP-related risk compensation attitudes among providers with firsthand experience prescribing PrEP...

INTRODUCTION: The increasing availability of antiretroviral drugs has made HIV-positive patients to live longer, and conditions that are associated with longevity such as metabolic syndrome and other cardiovascular related conditions have become relevant in them. This is less well studied among African populations. Therefore the study aimed at estimating and comparing the prevalence of and associated risk factors for the metabolic syndrome (MS) among African HIV infected patients. METHOD: In this comparative cross-sectional study, we analyzed the data of 300 participants matched for age and gender who satisfied the inclusion criteria with half of the subjects on HAART, while the other half was HAART naïve...

Human immunodeficiency virus (HIV) infection remains a global pandemic. The primary driver of HIV incidence is sexual transmission between serodifferent individuals. Condoms, when used consistently and correctly, are effective at preventing sexually-transmitted HIV infections, and are considered an integral component of a comprehensive approach to HIV prevention. However, the demonstrated effectiveness of antiretroviral therapy (ART) to prevent HIV transmission, known as treatment as prevention, and of pre-exposure prophylaxis, have raised an intriguing dilemma on the necessity and additive preventive benefit of condom use among individuals in serodifferent relationships utilizing these prevention strategies...

A few studies suggest that women who experience intimate partner violence (IPV) are willing to use pre-exposure prophylaxis (PrEP), but no research has examined mediators of this relationship. The current study used path analysis to examine a phenomenon closely associated with IPV: reproductive coercion, or explicit male behaviors to promote pregnancy of a female partner without her knowledge or against her will. Birth control sabotage and pregnancy coercion-two subtypes of reproductive coercion behaviors-were examined as mediators of the relationship between IPV and PrEP acceptability among a cohort of 147 Black women 18-25 years of age recruited from community-based organizations in an urban city...
