Despite all the efforts to contain the HIV/AIDS epidemics there still are individuals of unknown diagnosis. These present high risk of mortality, and following diagnosis respond very poorly to treatment. Late testing also represents a reduced opportunity in controlling the transmission of HIV and causes an indirect increase in the transmission rates of other diseases, such as tuberculosis. In European countries, as well as in the United States, a great number of people, represented specially by illegal immigrants, black individuals and women markedly present at a later state of infection...

Prevention of mother-to-child transmission (PMTCT) guidelines recommend that all HIV-infected pregnant woman receive antiretroviral therapy (Option B) and HIV-infected infants should initiate therapy with a protease inhibitor based regimen; however, implementation of these guidelines has lagged in many resource-limited settings. Tanzania only recently implemented these guidelines with little country specific data to inform whether HIV non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance was present among infected infants under the Option A guidelines...

Maraviroc (MVC) is an allosteric inhibitor of HIV-1 entry, and is the only CCR5 antagonist licensed for use as an anti-HIV-1 therapeutic. It acts by altering the conformation of the CCR5 extracellular loops, rendering CCR5 unrecognizable by the HIV-1 envelope glycoproteins (Env). This study aimed to understand the mechanisms underlying the development of MVC resistance in HIV-1-infected patients. To do this, we obtained longitudinal plasma samples from 8 subjects who experienced treatment failure with phenotypically verified, CCR5-tropic MVC resistance...

Co-circulation of multiple subtypes in same population contributes significantly to the emergence of recombinant viruses. BJ2015EU19, a novel CCR5-tropic HIV-1 second-generation recombinant virus,was isolated from a man who has sex with man in Beijing, China. Phylogenetic analysis of the near full-length genome showed that BJ2015EU19 was consisted of seven fragments from CRF01_AE and CRF07_BC. There were six recombinant breakpoints in the pol, vpu, env and nef genes of BJ2015EU19,which were different from the other circulating recombinant forms and unique recombinant forms...

The delay between first-line antiretroviral therapy (ART) failure and initiation of second-line ART - in resource-limited settings - can be prolonged. Increasing evidence links delayed antiretroviral switch with increased risk for opportunistic infection (OI) and death, particularly in patients with advanced HIV at the time of first-line failure. As access to viral load monitoring widens beyond a few countries, mechanisms are needed to optimize the use of routine virologic monitoring and assure that first-line regimen failure results in prompt second-line switch...

Historically, Indian origin rhesus macaques (iRM) have been preferred for SIV/HIV prevention, pathogenesis, and treatment studies, yet their supply is limited. Chinese origin rhesus macaques (cRM) are currently more available yet little is known regarding the relative susceptibility of this subspecies to vaginal transmission of SIV or SHIV. Here we compared the susceptibility of 40 cRM and 21 iRM to a single vaginal challenge with SHIVsf162P. Our results showed cRM have comparable primary SHIV infection as iRM, underscoring their equal importance in studies of HIV transmission and prevention...

A 10-year review of disseminated MAC infection and MAC-Immune Reconstitution Inflammatory Syndrome (IRIS) in HIV-positive patients (2004-2014) at a state-wide tertiary referral HIV service, demonstrates that despite advances in antiretroviral therapy, MAC infection remains a therapeutic challenge, particularly intra-abdominal disease.

The persistence of HIV infection, even after lengthy and successful combined antiretroviral therapy (cART), has precluded an effective cure. The anatomical locations and biological mechanisms through which the viral population is maintained remain unknown. Much research has focused nearly exclusively on circulating resting T cells as the predominant source of persistent HIV, a strategy with limited success in developing an effective cure strategy. In this study, we review research supporting the importance of anatomical tissues and other immune cells for HIV maintenance and expansion, including the central nervous system, lymph nodes, and macrophages...

Current serological assays that are used for cross-sectional HIV incidence estimation have been shown to misclassify individuals with chronic infection. Limited information exists on the performance of cross-sectional incidence assays in Central Africa. HIV-positive individuals from Cameroon who were infected for at least 1 or 2 years were evaluated to determine the false recent ratio (FRR) of a two-assay algorithm, which includes the Limiting Antigen Avidity (LAg-Avidity) assay (normalized optical density units, ODn <1...

Vitamin D may play an important role in a range of disease processes. In the general population, lower vitamin D levels have been associated with kidney dysfunction. HIV-infected populations have a higher risk of chronic kidney disease. Few studies have examined the link between lower vitamin D levels and kidney function decline among HIV-infected persons. We investigated the associations of serum 25-hydroxyvitamin D [25(OH)D] and 1,25-dihydroxyvitamin D [1,25(OH)2D] with kidney function decline in a cohort of HIV-infected white and black men under HAART treatment in the vitamin D ancillary study of the Multicenter AIDS Cohort Study (MACS)...

HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic demyelinating and disabling syndrome caused by human T lymphotropic virus 1 (HTLV-1). Although the pathogenic mechanisms that lead to HAM/TSP outcome have not been elucidated, genetic and immunological factors may be involved in the myelopathy occurrence. This study aimed to compare cytokines, chemokines, and nitric oxide (NO) levels in asymptomatic and HAM/TSP HTLV-1-infected patients. The study group consisted of 21 HAM/TSP and 48 asymptomatic HTLV-1 patients...

HECT domain and RCC1-like domain-containing protein 5 (HERC-5) is one of the novel host restriction factors that is known to inhibit HIV release in vitro. Polymorphisms in other host restriction factors have been associated with HIV infection and disease progression. However, no report is available on the HERC-5 polymorphism in HIV-infected individuals. We studied the HERC-5 gene polymorphism in HIV-infected individuals and explored whether it is associated with different disease outcomes. Genomic DNA was isolated from 41 HIV-1 progressors, 39 long-term nonprogressors, and 74 HIV seronegative healthy donors for amplification of HERC5 Exon-18 and other regulatory regions followed by sequencing...

Dolutegravir (DTG) is an integrase strand transfer inhibitor that is used for the treatment of HIV infection. DTG inhibits organic cation transporter 2 on the basolateral side of proximal tubule cells of the kidney and leads to increased serum creatinine levels without true renal function deterioration. In HIV patients who receive DTG, an alternative test to serum creatinine measurement is needed to determine the correct renal function. We retrospectively evaluated 18 HIV-infected men who had received combination antiretroviral therapy (cART), including DTG, and who had available data on serum creatinine and cystatin C levels...

In this study, a novel CRF01_AE/07_BC HIV-1 recombinant form, with five breakpoints in thepol, vpr, env and nef gene regions, was identified from a voluntary blood donor in North China. Our study showed that this HIV-1 recombinant form might be a second-generation recombinant form from two predominant strains inthe Men who have sex with men (MSM) population, with the CRF07_BC fragments belonging to a CRF07_BC lineage specific to Chinese MSM and the CRF01_AE fragments belonging to the CRF01_AE lineage 5 common among MSM in northern China...

Human immunodeficiency virus type 1 (HIV-1) is the major cause of acquired immunodeficiency syndrome (AIDS) in humans, where the immune system totally succumbs to the virus. A large proportion of the AIDS infected belong to developing countries and AIDS prevalence is intensified by severe poverty, malnutrition, and famine; fatal illnesses with a scorn shortage of medical amenities complemented with the lack of education and development. Current Pakistani health system setting is in a dire need of improvement...

Strategies to control HIV in the absence of antiretroviral therapy are needed to cure HIV. However, such strategies will require analytical treatment interruptions (ATIs) to determine their efficacy. We investigated how U.S. stakeholders involved in HIV cure research perceive ATIs. We conducted 36 in-depth interviews with three groups of stakeholders: 12 people living with HIV, 11 clinician-researchers, and 13 policy-makers/bioethicists. Qualitative data revealed several themes. First, there was little consensus on when ATIs would be ethically warranted...

In China, CRF01_AE and CRF07_BC are the most circulating strains of HIV-1, more and more second-generation recombinant forms have been isolated around the two strains. The same situation happened in Beijing in recent years. In our study, we have isolated a new second-generation recombinant form of HIV-1 from a male patient who was infected by homosexual behavior. Polygenetic analysis revealed that the sequence includes five CRF01_AE fragments and four CRF07_BC fragments. CRF01_AE is the skeleton of the recombinant which was inserted with four CRF07_BC fragments...

A sharp increase in the number of people living with HIV has been documented in the Philippines. In response, the government has instituted antiretroviral therapy (ART) nationwide through HIV treatment hubs. However, no data presently exist on the status of ART drug-resistance-associated mutations (DRMs). In this study, we aim at analyzing DRM profiles in the Philippines and at providing comprehensive data on DRMs to guide treatment decisions and prevent viral failures. We conducted a cross-sectional study in 119 volunteers who tested positive for HIV from more than 8,000 participants screened for HIV across the nation through the 2013 Integrated HIV Behavioral and Serologic Surveillance (IHBSS) program...

Hypertension is a growing problem in the HIV population. The relationship between low nadir CD4 count and hypertension in the HIV-infected population has been reported. However, the effect of nadir CD4 on hypertension due to a different body mass index (BMI) is yet to be fully elucidated. In this cross-sectional study, 345 HIV-infected participants aged ≥40 years were recruited. They were frequency matched and compared with age, sex, and education with HIV-uninfected adults (n = 345). Hypertension prevalence was lower in HIV-infected than in HIV-uninfected participants (23...
