HIV and tuberculosis are among the global deadliest diseases. Migrant populations are particularly vulnerable to these infections. Yet, literature is still scarce on the epidemiology of HIV-TB co-infection among migrants. In this study, we characterized native and migrant HIV patients followed in Portuguese hospitals who were diagnosed with TB, regarding their sociodemographic, clinical and genomic

Attempts to develop a protective HIV vaccine have had limited success, especially in terms of inducing protective antibodies capable of neutralizing different viral strains. As HIV transmission occurs mainly via mucosal surfaces, HIV replicates significantly in the gastrointestinal tract, and the oral route of vaccination is a convenient one to implement worldwide, we explored three SIV vaccine modalities

N/A

Understanding the evolutionary dynamics of the viruses within an individual at or near the moment of transmission can provide critical inputs for the design of an effective vaccine for HIV infection. In this study, high-throughput sequencing technology was employed to analyze the evolutionary rate in viruses obtained at a single time point from drug-naive recently infected infants and adults in the

While antiretroviral therapy (ART) effectively suppresses HIV replication, the latent reservoir remains the barrier to HIV eradication. It remains unknown whether long term ART impacts levels of inducible replication-competent provirus. To address this knowledge gap, we assessed the proviral reservoir in HIV-1 perinatally infected adolescents having received ART for over 13 years. We recruited 15 vertically

A primary concern of an antibody-based HIV-1 therapy is the virus’ ability to rapidly escape antibody responses. Therefore, we investigated the relationships between antibody neutralization sensitivity, viral phenotype and infectivity in 13 subtype C viruses using a HeLa transfectant-based assay. We observed that the seven tier 3 viruses exhibited higher infectivity than the tier 2 viruses, suggesting

A significant weight gain has been reported in HIV-infected patients starting combination antiretroviral therapy (cART) including integrase strand transfer inhibitors (INSTIs), but clinical data about changes in body fat mass are still lacking. An observational, retrospective analysis was made to evaluate changes in body fat mass and weight in 39 cART-naïve patients initiating a first antiretroviral

A growing body of research is beginning to elucidate reasons people living with HIV (PLWHIV) might prefer oral daily antiretroviral treatment (ART) compared with emerging long-acting ART (LA-ART) or HIV remission strategies under investigation. Our objective is to provide qualitative insights into the reasons why PLWHIV might prefer one of these HIV control therapies over others. From May to August

Antiretroviral treatment based on tenofovir alafenamide fumarate (TAF) is increasingly recommended, as it maintains the viral suppression and improves renal function and bone density in comparison with tenofovir disoproxil fumarate (TDF). We carried out a retrospective cohort study including experienced patients who switched treatment from TDF to TAF. Serum lipids and glucose, renal function, body

Mitochondrial dysfunction (MD) is linked to cardiometabolic complications, such as obesity and insulin resistance (IR), the frequencies of which are higher in adults living with HIV infection and receiving combination antiretroviral therapies (ARV). ARV-treated youth living with perinatally acquired HIV infection (YLPHIV) may be especially susceptible to IR due to long-term exposure to both factors

Despite the implementation of health education and free condom distribution for decades, the HIV/AIDS epidemic among older adults in China shows no sign of declining. This study aims to identify HIV transmission patterns and pathways in a rural county area and provide insight for developing effective HIV prevention strategies among older adults. Epidemiological field surveys combined with phylogenetic

Pre-Exposure Prophylaxis (PrEP) has been widely accepted as an effective method to prevent HIV infections, but high costs precluded a widespread use in Germany. A novel distribution pathway of tenofovir-disoproxil fumarate and emtricitabine PrEP was implemented, which reduced monthly PrEP costs by 16-fold in Germany. Over a period of 6 months, we recorded prescription data, demographics, and sexual

The role of HIV infection in precipitating different clinical features in cryptococcal meningitis (CM) patients remains controversial. One hundred twelve CM patients living with HIV/AIDS (CM+HIV+ patients) and 112 CM patients living without HIV/AIDS (CM+HIV− patients) were enrolled after propensity score matching. Demographic characteristics, symptoms, routine blood tests, and biochemical and cerebrospinal

Unhealthy alcohol use is prevalent among persons living with HIV (PLWH). Aging and increased survival of PLWH on antiretroviral therapy (ART) are complicated by metabolic dysregulation and increased risk of insulin resistance (IR) and diabetes mellitus. The objective of this study was to determine the prevalence and association of IR with unhealthy alcohol use in adult in-care PLWH. A cross-sectional

Assessment tools are necessary for the adequate stratification of patients with AIDS-related pneumocystis pneumonia (PCP). The aim of this study was to evaluate the ability of severity assessment scores and inflammation- and nutrition-based parameters for predicting the 180-day mortality of AIDS-related PCP. This was a retrospective cohort study of patients with AIDS-related PCP admitted at the Beijing

A tremendous loss of financial and human resources from seven large-scale HIV vaccine efficacy trials suggest a need for a systematic approach to vaccine selection. We conducted a systematic analysis of three important envelope glycoprotein (Env) vaccine candidates: BG505 SOSIP.664, 1086.C gp140, and 1086.C gp120 to determine the most promising by comparing their structure and antigenicity. We found

Among transgender women (TGW), the effects of feminizing hormone therapy use on rectal mucosal (RM) HIV transmission are largely unknown. In this small pilot study, we compared the RM transcriptome in TGW utilizing feminizing hormone therapy with a group of cisgender men who have sex with men (MSM) engaging in condomless receptive anal intercourse (AI) and to a group of cisgender men who had never

This study aimed to ascertain the patterns of human immunodeficiency virus (HIV) risk behaviors among young men who have sex with men (YMSM) and explore the relationships between personality traits and patterns of HIV risk behaviors. Three hundred and seventy-five YMSM were recruited from March to December 2013, in central China. Latent class analysis (LCA) was utilized to identify underlying subgroups

HIV drug resistance (HIVDR) is of increasing health concern, especially among key populations. We investigated the prevalence of virological suppression (VS), prevalence and correlates of HIVDR in HIV-infected women, enrolled in a high-risk cohort. We enrolled 267 women initiated on first-line antiretroviral therapy (ART) between 2015 and 2018. Participants' plasma samples were analyzed for HIV RNA

To explore the molecular epidemiological status of human immunodeficiency virus type 1 (HIV-1) in Ganzhou, China, eight HIV-1–positive outpatients were recruited from July 5 to 21, 2018. Six HIV-1 near-full-length sequences were amplified and sequenced from the plasma samples that were collected before the patients' antiretroviral treatments. Phylogenetic and bootscan analyses revealed that one of

Transmitted drug resistance (TDR) in treatment-naive HIV patients can contribute to failure of initial antiretroviral therapy. In Korea, there has been a gradual increase in TDR, but the recent increase in the use of integrase strand transfer inhibitors (INSTIs) could affect TDR trends and INSTI resistance mutations. We evaluated the patterns of TDR in newly diagnosed HIV patients over time from 2011

In October of 2019, researchers and community members from around the world met at the NIH for the fifth annual International Workshop on Microbiome in HIV. New research was presented on the role of the microbiome on chronic inflammation and vaccine design, interactions of genetics, environment, sexual practice and HIV infection with the microbiome and the development and clinical trials of microbiome-based

C–C chemokine receptor (CCR) 5 (CCR5) is the main HIV-1 coreceptor involved in virus entry and cell-to-cell spread during acute and chronic infections: such CCR5 and T cell tropic viruses are adapted to and replicate in CD4+ memory T cells. Polymorphisms in CCR5 regulate CCR5 expression, which, in turn, influences HIV infection acquisition and subsequent disease progression. Among these polymorphisms

Latinx people living with HIV (PLWH) experience disparities in health outcomes and face unique barriers to care related to language, intersectional stigma, and immigration status. We aimed to explore the lived experience of Spanish-speaking Latinx PLWH in the nonurban South to better understand how to improve care for this minority language population. We conducted semistructured interviews with 22

To identify genotype distribution and drug resistance in people infected by HIV-1 in Wuhan, China, 105 infected people diagnosed with HIV-1 from January to December in 2019 were involved in this study. 98 gag genes, 101 PR genes and 98 RT genes were successfully amplified. The phylogenetic analysis results showed that CRF01_AE (38.2%) and CRF07_BC (35.3%) were the two dominant genotypes, followed by

Objective: To evaluate the national prevalence of antiretroviral therapy (ART)-resistant HIV-1 viruses among both ART-initiators (pre-treatment resistance, PDR) and ART-failured HIV patients in Uzbekistan. Methods: A nation-wide, cross-sectional active HIV-1 PDR surveillance was conducted in Uzbekistan from 2015-2016. In total, 713 blood plasma samples from adults were collected including samples from

Multiple HIV-1 genotypes were found circulating in Guangdong Province, China, as this province is located in South China and has a high frequency of international trade. Here, we report the near full-length genome of CRF12_BF that was identified from a male patient in Guangzhou city, Guangdong Province; this is the first time CRF12_BF has been reported in mainland China. The near full-length genome

Natural killer (NK) cells provide some of the earliest immune responses to infection, but when viruses manipulate or perturb the immune environment to alter NK cell function this places the host at a disadvantage. Indeed, others and we observe that in the context of HIV/SIV infection, although NK cells are not infected they can become dysfunctional over time. Several works have characterized protein

We aim to determine the prevalence of HIV nonsuppression and factors associated with it. This is a cross-sectional multicenter study carried out in January 2016 with data of the VACH Cohort, a registry participated by 23 hospitals from most regions of Spain. The prevalence of HIV nonsuppression, defined as HIV RNA ≥200 copies/mL, is documented. The possible association of HIV nonsuppression with sociodemographic

People living with HIV (PLWH) who are on protease inhibitor (PI)-containing regimens have been shown to have increases in visceral adipose tissue (VAT) and a greater decrease in spine bone mineral density (BMD) than those receiving non-PI regimens when initiating treatment. This increase in VAT has been hypothesized to falsely lower spine BMD measured via dual-energy X-ray absorptiometry, suggesting

Despite the success of antiretroviral therapy (ART), ART fails to eradicate the virus and HIV cure has remained beyond the reach of current treatments. ART targets replicating virally infected but not latently infected cells, which have limited expression of factors important for proliferation and cellular activity, including positive transcription elongation factor b (P-TEFb) and nuclear factor κB

Poor access to HIV viral load (VL) testing prevents the timely monitoring of HIV treatment adherence and efficacy. Factors enabling clinical benefits of VL testing when added to local standards of care, can inform the development of more cost-effective routine VL scale-up plans. We compared antiretroviral therapy (ART) switch practices in 13 clinics across 6 countries, with full (N = 8), phasing-in

The prevalence of HIV-1 drug resistance is increasing worldwide and monitoring its emergence is important for the successful management of populations receiving combination antiretroviral therapy. It is likely that pre-existing drug resistance mutations linked on the same viral genomes are predictive of treatment failure. Because of the large number of sequences generated by ultrasensitive single-genome

A wide variety of HIV-1 recombinants are constantly discovered in China. Comprehensively monitoring the genetic diversity of HIV-1 is very essential for understanding the molecular epidemiology and controlling the spread of the HIV-1 epidemic. In this study, we presented a novel HIV-1 unique CRF01_AE/C recombinant (19YA001) isolated from a female patient infected HIV-1 through heterosexual transmission

Background Maximum carotid plaque thickness (MCPT) measures the largest plaque thickness in the carotid artery and reflects atherosclerosis plaque burden. MCPT may be a better predictor of cardiovascular disease than carotid artery intima-media thickness (cIMT) because it identifies potential unstable arterial atherosclerosis plaques. We assessed the relationships of monocyte (MO) and T-cell populations

Gene editing approaches using CRISPR/Cas9 are being developed as a means for targeting the integrated HIV-1 provirus. Enthusiasm for the use of gene editing as an anti-HIV-1 therapeutic has been tempered by concerns about the specificity and efficacy of this approach. Guide RNAs (gRNAs) that target conserved sequences across a wide range of genetically diverse HIV-1 isolates will have greater clinical

With increasing effectiveness of antiretroviral therapy, people with HIV (PWH) are living longer and the prevalence of older PWH continues to increase. Accordingly, PWH are experiencing an increased burden of age-related comorbidities. With this shifting demographic, clinicians and researchers face additional challenges in how to identify, address, and manage the complex intersections of HIV- and aging-related

Little is known about the characteristics of SARS-CoV-2 infection in immunosuppressed people living with HIV. This report describes a case of a HIVinfected patient with Pneumocystis jirovecii pneumonia and CoVid-19 who died because of treatment’s side effect. This case teaches us that fragile people may need different therapeutic strategies.

HIV-TRAnsmission Cluster Engine (HIV-TRACE) and Cluster Picker are some of the most widely used programs for identifying HIV-1 transmission networks from nucleotide sequences. However, choosing between these tools is subjective and often a matter of personal preference. Because these software use different algorithms to detect HIV-1 transmission networks, their optimal use is better suited with different

Data on the prevalence of double infection (DI) in HIV individuals are lacking in Spain. To fill this gap, we analyzed the prevalence of DI in a cohort of men who have sex with men (MSM) and examined factors contributing to DI. We selected 81 MSM attending Centro Sanitario Sandoval, a sexually transmitted diseases clinic in Madrid. We obtained by ultra-deep sequencing the proviral sequences in gag

In our study, we reported a novel CRF01_AE/B/C human immunodeficiency virus type 1 (HIV-1) recombinant form among six epidemiologically unlinked heterosexual patients in Yunnan, China. It was named CRF106_cpx (this is temporary as we have not received the circulating recombinant form [CRF] number from HIV databases). After sequencing and analyzing of the near full-length genome, we found that CRF106_cpx

We reported a novel HIV-1 circulating recombinant form among four epidemiologically unlinked patients through men having sex with men (MSM) in HeiLongjiang Province, China. It was named CRF107_01B (this is temporary as we have not received the CRF number from HIV databases). A near full-length genome (NFLG) phylogenetic tree showed that CRF107_01B was generated by two CRF01_AE segments that was described

Previous studies have shown that HIV-infected individuals were less susceptible to chronic gastritis and Helicobacter pylori infection. Th1 and Th17 cells are important components of the immune response to H. pylori in adults. We investigated the relative importance of Th1 versus Th17 responses for mucosal inflammation and protection. We conducted a prospective cross-sectional study to evaluate the

Diversity of genotypes and prevalence of pretreatment drug resistance (PDR) are challenges for the epidemic control and vaccine development of HIV-1. However, little is known about the situation in Tianjin. Blood samples were collected from newly diagnosed, antiretroviral treatment (ART)-naive HIV/AIDS patients from January 2016 to November 2019. The target fragment in the pol gene was sequenced after

Microbial translocation has been suggested as a major driver of chronic immune activation HIV infection. Thus, we compared the extent of microbial translocation in patients with acute HIV infection and patients followed after CD4-guided structured treatment interruption (STI) by measuring different circulating markers: (1) lipopolysaccharide (LPS)-binding protein (LBP), (2) bacterial DNA, (3) soluble

Advanced age is a high-risk factor for exacerbation of coronavirus disease 2019 (COVID-19), which causes a high rate of mortality. Therefore, it is important to strengthen the warning and monitoring of severe patients, and early identify the severe and critically severe types in time in the clinical treatment of COVID-19. Moreover, it is necessary to pay attention to the adverse reactions and damage

The HIV-1 epidemic has continued to grow in Indonesia; however, continuous updates on the epidemiology of HIV-1 in Indonesia remain challenging because it is the biggest archipelago in the world. Furthermore, the emergence of HIV drug resistance (HIVDR) has had a negative impact on the treatment of infected individuals. In the present study, we performed HIV-1 subtyping and the detection of HIVDR in

Insurance enrollment is complex for people living with HIV (PLWH) and people at increased risk for HIV, in part, owing to needing to ensure access to adequate provider networks and appropriate formularies. Insurance for PLWH facilitates access to HIV care/treatment and, ultimately, viral suppression, which has the individual benefit of longevity and the public health benefit of decreased HIV transmission

We identify factors associated with the normalization of the CD4+:CD8+ T cell ratio among UK Collaborative HIV Cohort study participants, and describe the association of the CD4+ and CD8+ T cell counts and the CD4+:CD8+ T cell ratio, with the risk of new AIDS events among individuals who achieve a suppressed viral load. Participants initiating combination antiretroviral therapy (cART) after 2006 with

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the etiologic agent of COVID-19, a disease that as of July 10, 2020, has infected >12 million people and killed >500,000. COVID-19 infection leads to acute respiratory distress syndrome in a subset of patients and is a primary driver of acute morbidity in infected persons. However, it is becoming increasingly clear that SARS-CoV-2 infection

HIV-1 integrase (IN) is a primary target for combination antiretroviral therapy. Only a limited number of studies report on the emergence of resistance-associated mutations (RAMs) in Cameroon. We observed that 1.4% of sequence from treatment-naive patients had IN strand transfer inhibitor (INSTI) RAMs. These mutations confer resistance to raltegravir and elvitegravir. We also observed that 10.1% of

Limited data exist on the effects of contraceptives on HIV disease progression. We studied the association between intramuscular injectable depot medroxyprogesterone acetate (DMPA-IM), the copper intrauterine device (IUD), and the levonorgestrel (LNG) implant on markers of HIV disease progression at the time of HIV detection and 3 months postdetection and time from detection to CD4 count <350 cells/mm3

This study aims to evaluate the epidemiological characteristics of mother-to-child transmission (MTCT) of HIV and identify the possible factors leading to infant HIV infection using a retrospective cohort study of early infant diagnosis (EID). Information on a total of 3,145 exposed infant–mother pairs was collected from the EID platform from July 2014 to December 2019. The MTCT rate was 2.1%. Spatial–temporal

Overlap in metabolism pathways of endogenous female sex hormones and antiretroviral drugs may lead to altered exposure to these compounds. In a family planning clinic in Lilongwe, Malawi, blood, blood cell, and cervicovaginal fluid (CVF) samples from seventy-three HIV positive Malawian women taken in follicular and luteal menstrual phases were assessed for estradiol and progesterone by chemiluminescent

Between October 2015 and August 2016, Zimbabwe conducted the Zimbabwe Population-Based HIV Impact Assessment (ZIMPHIA) cross-sectional survey to determine progress toward epidemic control. Of 25,131 eligible adults aged 15–64 years, 20,577 (81.8%) consented to face-to-face questionnaire and biomarker testing in this nationally representative household survey. Home-based rapid HIV testing was performed

People living with HIV (PLWH) experience chronic pain that may impact function. Gaps in knowledge exist for factors that impact pain and pain medication use in older (age 50+) PLWH. Data for this study were obtained from the Aging with Dignity, Health, Optimism and Community (ADHOC) cohort, an observational study of older PLWH from 10 clinics across the United States. Participants self-reported socioeconomic

People living with HIV (PLH) may be at increased risk of experiencing both chronic pain and opioid dependence. Physical therapy (PT) has been shown to be effective as a nonpharmacological strategy for mitigating chronic pain in the general population, however, there is gap in research investigating PT to reduce chronic pain and opioid use among PLH. This case series describes the feasibility of an

Low serum vitamin D levels are very common in human immunodeficiency virus (HIV)-infected patients. In our cross-sectional study, we investigated the association between 25-hydroxyvitamin D (25(OH)D) levels and serum inflammation markers [C-reactive protein (CRP), white blood cells (WBC), D-dimers, platelet count (PLT)] in 148 HIV-infected patients on combined antiretroviral therapy [28 on tenofovir

Non-nucleoside reverse transcription inhibitor (NNRTI)-containing antiretroviral therapy (ART) for the prevention of mother to child transmission (PMTCT) of human immunodeficiency virus (HIV) has led to dramatic reductions in perinatal HIV infection in resource-constrained settings. Nonetheless, PMTCT programs are complicated by repeat pregnancies, in which long-term or repeat exposures to PMTCT regimens
