BACKGROUND: The World Health Organization defines HIV virologic failure as two consecutive viral loads >1,000 copies/mL, measured 3-6 months apart with interval adherence support. We sought to empirically evaluate these guidelines using data from an observational cohort. SETTING: The Uganda AIDS Rural Treatment Outcomes study observed adults with HIV in southwestern Uganda from the time of antiretroviral therapy (ART) initiation, and monitored adherence with electronic pill bottles...

BACKGROUND: Initiating antiretroviral therapy (ART) early improves clinical outcomes and prevents transmission. Guidelines for first-line therapy have changed with the availability of newer ART agents. In this study, we compared persistence and virologic response to initial ART according to the class of anchor agent used. SETTING: An observational clinical cohort study in the Southeastern United States. METHODS: All HIV-infected patients participating in the UNC Center for AIDS Research Clinical Cohort (UCHCC) and initiating ART between 1996 and 2014 were included...

BACKGROUND: HIV-1 is known to adapt to the local environment in its usage of receptors and it can become CD4 independent in the brain where the receptor is scarce. This adaptation is through amino acid variations, but the patterns of such variation are not yet well understood. Given that infection of long-lived CD4-low and CD4-negative cells in anatomic compartments such as the brain expand cell tropism in vivo and may serve as potential viral reservoirs that pose challenge for HIV eradication, understanding the evolution to CD4-independence and envelope conformation associated with infection in the absence of CD4 will not only broaden our insights into HIV pathogenesis, but may guide functional cure strategies as well...

INTRODUCTION: Early diagnosis of HIV-1 infection and the prompt initiation of antiretroviral therapy are critical to achieving a reduction in the morbidity and mortality of infected infants. The SAMBA HIV-1 Qual Whole Blood Test was developed specifically for early infant diagnosis and prevention of mother-to-child transmission programs implemented at the point-of-care in resource-limited settings. METHODS: We have evaluated the performance of this test run on the SAMBA I semi-automated platform with fresh whole blood specimens collected from 202 adults and 745 infants in Kenya, Uganda, and Zimbabwe...

To expand upon our previous observation that HIV-1 Gag-specific IgG antibodies were highest in HIV controllers not carrying HLA-B*57:01, we analysed these antibodies in a larger cohort of viremic controllers (VCs) or elite controllers (ECs) considering carriage of 'protective' HLA-B alleles. HIV-1 p24-specific IgG1 and IgG2 antibodies were higher only in HLA-B*57:01 VCs but there were no differences in ECs. Associations of HIV-1 gp140-specific IgG antibodies with HLA-B*57:01 carriage were inconsistent amongst VCs and ECs...

BACKGROUND: The burden of HIV remains heaviest in resource-limited settings, where problems of losses to care, silent transfers, gaps in care, and incomplete mortality ascertainment have been recognized. METHODS: Patients in care at Academic Model Providing Access to Healthcare (AMPATH) clinics from 2001-2011 were included in this retrospective observational study. Patients missing an appointment were traced by trained staff; those found alive were counseled to return to care (RTC)...

OBJECTIVE: Events occurring during the initial phase of human immunodeficiency virus (HIV) infection are intriguing because of their dramatic impact on the subsequent course of the disease. In particular, the relationship between myeloid-derived suppressor cells (MDSCs) and HIV pathogenesis in primary infection remains unknown and the mechanism of MDSCs in HIV infection are incompletely defined. METHODS: The frequency of MDSC expression in patients with primary (PHI) and chronic HIV infection was measured, and the association with disease progression was studied...

BACKGROUND: Lack of accessible laboratory infrastructure limits HIV antiretroviral (ART) treatment initiation, monitoring and retention in many resource-limited settings. Point-of-care testing (POCT) is advocated as a mechanism to overcome these limitations. We executed a pragmatic, prospective, randomized, controlled trial comparing the impact of POCT versus standard-of-care (SOC) on treatment initiation and retention in care. METHOD: Selected POC technologies were embedded at 3 primary health clinics in South Africa...
