Interventions aiming to improve access to and retention in HIV care are optimized when they are tailored to clients' needs. This paper describes an initiative of interventions implemented by ten demonstration sites using a transnational framework to tailor services for Mexicans and Puerto Ricans living with HIV. Transnationalism describes how immigrants (and their children) exist in their "receiving" place (e.g., continental U.S.) while simultaneously maintaining connections to their country or place of origin (e...

OBJECTIVE: Therapeutic HIV-1 immunization followed by latency reversal has been suggested as a strategy to eradicate HIV-1. Here we investigate the phylogenetic composition of the HIV-1 regions targeted by the therapeutic HIV-1 peptide vaccine Vacc-4x in participants in a clinical trial. DESIGN: Seventeen participants on suppressive antiretroviral therapy were vaccinated with six doses of Vacc-4x followed by three doses of romidepsin. Seven study participants were selected for sequencing analysis...

HIV-positive children are still born in Europe despite low mother-to-child transmission (MTCT) rates. We aimed to clarify the remaining barriers to the prevention of MTCT. By combining the national registers, we identified all women living with HIV delivering at least one child during 1983-2013. Of the 212 women delivering after HIV diagnosis, 46% were diagnosed during the pregnancy. In multivariate analysis, age >30 years (P = 0.001), sexual transmission (P = 0.012), living outside of the metropolitan area (P = 0...

Although many oral ulcers have similar clinical appearances, their etiologies can range from reactive to neoplastic to oral manifestations of dermatological diseases. In patients with an HIV infection, fungal diseases may cause ulceration in the oral cavity; however, there have been few studies of oral ulcerative lesions associated with Candida in patients without an HIV infection. Nevertheless, we encountered chronic oral ulcer associated with Candida among our frequent outpatients without an HIV infection...

The purpose of our systematic review of research on chronic kidney disease (CKD) in persons living with HIV (PLWH) was to (a) compare and contrast diagnostic criteria for CKD, (b) identify risk factors of CKD in PLWH, and (c) elucidate the prevalence of CKD in PLWH. Keyword searches of PubMed and PsycInfo databases were followed by manual searches of references from 2000 through 2016; 21 studies met inclusion criteria. Sample sizes ranged from 8 to 15,140, with a mean age of 50 years, and represented diverse ethnicities/races and countries of origin...

In this paper, we report our investigations on analogues of the anti-human immunodeficiency virus type 1 (HIV-1) integrase (IN) aptamer T30175 in which the individual thymidines forming the loops were replaced by 5-hydroxymethyl-2'-deoxyuridine residues (H). Circular dichroism, nuclear magnetic resonance and gel electrophoresis investigations clearly indicated that all the modified aptamers preserve the ability to form the original 5'-5' end-stacked head-to-head dimeric G-quadruplex structure, in which each G-quadruplex adopts a parallel arrangement and is characterized by three G-tetrads, three propeller loops and one bulge-loop...

Human Myxovirus resistance 2 (huMxB) has been shown to be a determinant type I interferon-induced host factor involved in the inhibition of HIV-1 as well as many other primate lentiviruses. This blocking occurs after the reverse transcription of viral RNA and ahead of the integration into the host DNA, which is closely connected to the ability of the protein to bind the viral capsid. To date, Mx2s derived from non-primate animals have shown no capacity for HIV-1 suppression. In this study, we examined the restrictive effect of equine Mx2 (eqMx2) on both the equine infectious anemia virus (EIAV) and HIV-1 and investigated possible mechanisms for its specific function...

The Phase III RV144 HIV vaccine trial conducted in Thailand remains the only study to show efficacy in decreasing HIV acquisition risk. In Thailand, circulating recombinant forms of HIV clades A/E (CRF01_AE) predominate; in such viruses, env originates from clade E (HIV-E). We constructed a simian-human immunodeficiency virus (SHIV) chimera carrying env isolated from an RV144 placebo recipient in the SHIV-1157ipd3N4 backbone. The latter contains long terminal repeats (LTRs) with duplicated NF-κB sites, thus resembling HIV LTRs...

BACKGROUND: The overall success of Human immunodeficiency virus type 1 (HIV-1) antiretroviral therapy (ART) was heavily challenged upon the occurrence of drug resistance. Dehong Prefecture witnessed not only the first report of HIV-1 infection but also the experimental adoption of antiviral treatment in China. The transmission and epidemic of HIV-1 in Dehong is impacted by cross-border activities. The characteristics of HIV-1 drug resistance among therapy-naïve Burmese entering travelers in Yunnan and their speculated origin are still not clarified...

The process of finding new therapeutic indications for currently used drugs, defined as 'repurposing', is receiving growing attention. Chloroquine and hydroxychloroquine, with an original indication to prevent or cure malaria, have been successfully used to treat several infectious (HIV, Q fever, Whipple's disease, fungal infections), rheumatological (systemic lupus erythematosus, antiphospholipid antibody syndrome, rheumatoid arthritis, Sjögren's syndrome), and other immunological diseases. Indeed, they have anti-inflammatory, immunomodulating, anti-infective, antithrombotic, and metabolic effects...

CAP256 is one of the highly potent, broadly neutralizing monoclonal antibodies (bNAb) designed for HIV-1 therapy. During the process development of one of the constructs, an unexpected product-related impurity was observed via microfluidics gel electrophoresis. A panel of complementary LC-MS analyses was applied for the comprehensive characterization of CAP256 which included the analysis of the intact and reduced protein, the middle-up approach, and a set of complementary peptide mapping techniques and verification of the disulfide bonds...

Complex sugars found in breastmilk, human milk oligosaccharides (HMOs), may assist in early-life immune programming and prevention against infectious diseases. This study aimed to systematically review the associations between maternal levels of HMOs and development of immune-mediated or infectious diseases in the offspring. PubMed and EMBASE databases were searched (last search on 22 February 2018) according to a predetermined search strategy. Original studies published in English examining the effect of HMOs on immune-mediated and infectious disease were eligible for inclusion...

BACKGROUND: Although earlier protease inhibitors have been associated with increased risk of cardiovascular disease, whether this increased risk also applies to more contemporary protease inhibitors is unknown. We aimed to assess whether cumulative use of ritonavir-boosted atazanavir and ritonavir-boosted darunavir were associated with increased incidence of cardiovascular disease in people living with HIV. METHODS: The prospective Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study consists of people living with HIV-1 from 11 cohorts in Australia, Europe, and the USA...

INTRODUCTION: Late Diagnosis (LD) of Human Immunodeficiency Virus (HIV) infection (CD4 lymphocytes <350/μl at diagnosis of the disease), deteriorates the condition of those affected and increases the probability of transmission. The objective of the present study was to analyse the prevalence of LD, to identify missed diagnostic opportunities (MDO) and to find out which level of the health care delivery system they took place. METHODS: Retrospective, observational and descriptive study of the population diagnosed with infection of HIV/AIDS in the period 2011-2015 in Aragon...

This study reported a new HIV-1 circulating recombinant form CRF65_cpx virus isolated from a man who had sex with men (MSM) in Jilin, China. The near full-length genome of this virus was composed of fourteen mosaic gene fragments derived from CRF01_AE, subtype B' (Thai B) and subtype C, highly similar to the CRF65_cpx viruses recently identified in Yunnan and Anhui of China. Phylogenetic tree analysis suggested that this CRF65_cpx strain was not generated among MSM in Jilin, but originated in southern regions of China and spread to Jilin by MSM population...

Although rarely diagnosed in Switzerland, urinary tract schistosomiasis is common in the migrants' regions of origin, such as sub-Saharan Africa and the Middle East. Early recognition of this condition, even if asymptomatic, is crucial, because it increases the risk for HIV transmission and, if left untreated, can result in infertility and is associated with the development of bladder cancer. The diagnosis of urinary schistosomiasis should be especially suspected in case of terminal haematuria and eosinophilia in patients with a history of skin exposure to fresh water in endemic areas...

Background: Extracellular vesicles (EVs) are membrane bound, secreted by cells, and detected in bodily fluids, including urine, and contain proteins, RNA, and DNA. Our goal was to identify HIV and human proteins (HPs) in urinary EVs from HIV+ patients and compare them to HIV- samples. Methods: Urine samples were collected from HIV+ ( n = 35) and HIV- ( n = 12) individuals. EVs were isolated by ultrafiltration and characterized using transmission electron microscopy, tandem mass spectrometry (LC/MS/MS), and nanoparticle tracking analysis (NTA)...
