Fecal microbiota transplantation alters the proteomic landscape of inflammation in HIV: identifying bacterial drivers.

Background: Despite effective antiretroviral therapy, people with HIV (PWH) experience persistent systemic inflammation and increased morbidity and mortality. Modulating the gut microbiome through fecal microbiota transplantation (FMT) represents a novel therapeutic strategy. We aimed to evaluate proteomic changes in inflammatory pathways following repeated, low-dose FMT versus placebo.

Design and Proof of Concept of a Web-Based Questionnaire to Identify Patients at Risk for HIV and HCV Infection.

Despite remarkable improvement in the human immunodeficiency virus (HIV) and hepatitis C virus (HCV) care continuum, the rate of late diagnosis of HIV and HCV in high-income countries remains unacceptably high. Testing relies mainly on primary care physicians' identification of risk factors. We aimed to adapt an analogic to an online questionnaire to help HIV and HCV screening and perform a pilot study to assess its accuracy and acceptability.

Early Detection of Cancer and Precancerous Lesions in Persons with HIV through a Comprehensive Cancer Screening Protocol.

Background: Non-AIDS defining malignancies present a growing challenge for persons with HIV (PWH), yet tailored interventions for timely cancer diagnosis are lacking. The Spanish IMPAC-Neo protocol was designed to compare two comprehensive cancer screening strategies integrated into routine HIV care. This study reports baseline data on the prevalence and types of precancerous lesions and early-stage cancer among participants at enrolment.

Bictegravir/emtricitabine/tenofovir alafenamide as first-line treatment in naïve HIV patients in a rapid-initiation model of care: BIC-NOW clinical trial.

Objective: Multiple strategies have been utilised to reduce the incidence of HIV, including PrEP and rapid antiretroviral therapy initiation. The study objectives were to evaluate the efficacy, safety, satisfaction, treatment adherence, and system retention obtained with rapid initiation of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in naïve patients.

Methods: This phase IV, multicenter, open-label, single-arm, 48-week clinical trial enrolled patients between January 2020 and June 2022.

Global DNA methylation and telomere length as markers of accelerated aging in people living with HIV and non-alcoholic fatty liver disease.

Metabolic-dysfunction-associated fatty liver disease (MAFLD) is a comorbidity that generally increases in people living with HIV (PLWH). This condition is usually accompanied by persistent inflammation and premature immune system aging. In this prospective cohort study, we describe a straightforward methodology for quantifying biomarkers of aging, such as DNA methylation and telomere length, in PLWH and in the context of another relevant condition, such as MAFLD.

A Risk Assessment Tool for Predicting Fragility Fractures in People with HIV: Derivation and Internal Validation of the FRESIA Model.

People with HIV have a higher risk of fracture than the general population. Because of the low performance of the existing prediction tools, there is controversy surrounding fracture risk estimation in this population. The aim of the study was to develop a model for predicting the long-term risk of fragility fractures in people with HIV.

Effectiveness and safety of integrase strand transfer inhibitors in Spain: a prospective real-world study.

Introduction: Second-generation integrase strand transfer inhibitors (INSTIs) are preferred treatment options worldwide, and dolutegravir (DTG) is the treatment of choice in resource-limited settings. Nevertheless, in some resource-limited settings, these drugs are not always available. An analysis of the experience with the use of INSTIs in unselected adults living with HIV may be of help to make therapeutic decisions when second-generation INSTIs are not available.

Impact of COVID-19 on the Care of Patients with HIV Infection.

The COVID-19 pandemic and associated lockdown measures have been associated with substantial disruptions to health care services, including screening for human immunodeficiency virus (HIV) and management of people living with HIV (PLWH). Data from 3265 patients were examined in a retrospective cohort study. We compared outpatient follow-up for PLWH, the number of new patients, treatment adherence, hospitalizations, and deaths during the "pandemic period" (March 2020 to February 2021), the "pre-pandemic period" (the equivalent time frame in 2019), and the "post-pandemic period" (March to September 2021).

Improving Recognition of Fracture Risk in People with Human Immunodeficiency Virus: Performance and Model Contribution of Two Common Risk Assessment Tools.

Current guidelines recommend screening people with HIV (PWH) for bone disease using predictive tools developed for the general population, although data on PWH are scarce. In this study, we assessed the performance of FRAX and QFracture scoring systems to predict the occurrence of fragility fractures in a prospective cohort of 17,671 adults with human immunodeficiency virus (HIV) included in the HIV/AIDS research network (CoRIS) in Spain. The survival estimates of fragility fractures during follow-up were calculated and FRAX and QFracture scores were computed at cohort inclusion.

HTLV-2 Enhances CD8 T Cell-Mediated HIV-1 Inhibition and Reduces HIV-1 Integrated Proviral Load in People Living with HIV-1.

People living with HIV-1 and HTLV-2 concomitantly show slower CD4 T cell depletion and AIDS progression, more frequency of the natural control of HIV-1, and lower mortality rates. A similar beneficial effect of this infection has been reported on HCV coinfection reducing transaminases, increasing the spontaneous clearance of HCV infection and delaying the development of hepatic fibrosis. Given the critical role of CD8 T cells in controlling HIV-1 infection, we analysed the role of CD8 T cell-mediated cytotoxic activity in coinfected individuals living with HIV-1.

Unravelling hip-spine bone mineral density discordance in people living with HIV.

Introduction: In people living with HIV (PLWH), bone mineral density (BMD) discordance between the lumbar spine (LS) and femoral neck (FN) could be frequent given the high frequency of secondary osteoporosis, including HIV-related factors for bone disease.

Materials And Methods: Retrospective cohort of PLWH with a dual X-ray absorptiometry scan. Hip-spine BMD discordance was defined as different T-score or Z-scores categories at LS and FN.

Implementation of a lung cancer screening initiative in HIV-infected subjects.

In this pilot program of low-dose computed tomography (LDCT) for the screening of lung cancer (LC) in a targeted population of people with HIV (PWH), its prevalence was 3.6%; the number needed to screen in order to detect one case of lung cancer was 28, clearly outweighing the risks associated with lung cancer screening. While data from additional cohorts with longitudinal measurements are needed, PWH are a target population for lung cancer screening with LDCT.

Management of Comorbidities in Treated HIV Infection: A Long Way to Go: HIV, comorbidities and aging.

Modern ART has now achieved the goal of maintaining HIV RNA suppression with minimum drug-related toxicities. Indeed, in high-income settings, the main health issues in adult people living with HIV (PLWH) today are diseases not directly associated with HIV. These conditions have become the central topic of discussion in HIV clinical forums.

Progression Risk in People with HIV and COVID-19: Predictive Performance of Current Risk Scores.

People with HIV (PWH) might have a higher risk of adverse coronavirus disease 2019 (COVID-19) outcomes. Several scores were developed to predict COVID-19 progression to critical disease and are often used among PWH. We assessed the performance of two commonly used risk equations among PWH and COVID-19.

Fecal microbiota transplantation in HIV: A pilot placebo-controlled study.

Changes in the microbiota have been linked to persistent inflammation during treated HIV infection. In this pilot double-blind study, we study 30 HIV-infected subjects on antiretroviral therapy (ART) with a CD4/CD8 ratio < 1 randomized to either weekly fecal microbiota capsules or placebo for 8 weeks. Stool donors were rationally selected based on their microbiota signatures.

Randomized Trial Evaluating the Neurotoxicity of Dolutegravir/Abacavir/Lamivudine and Its Reversibility After Switching to Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide: GESIDA 9016.

Background: Despite evidence shown of dolutegravir (DTG)-related neurotoxicity, which may be more common when combined with abacavir (ABC), its reversibility has not been explored in a clinical trial.

Methods: We conducted a randomized, multicenter, open-label, pilot trial to evaluate the reversibility of patient-reported neuropsychiatric symptoms, developed or worsened on DTG/ABC/lamivudine (DTG/ABC/3TC), in virologically suppressed patients switched to cobicistat-boosted-elvitegravir/emtricitabine/tenofovir-alafenamide (EVG/COBI/FTC/TAF). Participants were randomized to immediate switch (baseline) or to defer switch (week 4), and then all completed 24 weeks of follow up on EVG/COBI/FTC/TAF.

Prevalence of low bone mass in individuals with HIV infection.

Background And Aims: There are no population data on bone mass in individuals with HIV in Spain, adjusted for age and sex.

Materials And Methods: Bone mineral density (BMD) data were obtained by dual X-ray absorptiometry in a cohort of individuals with HIV infection compared with cohort data from the general population in Spain and the United States of America.

Results: Of 928 individuals (mean 46 years, 25% women), the prevalence of osteoporosis in the lumbar spine/femoral neck was 18%/5% in men, and 17%/10% in women, respectively.

Hepatitis C and HIV combined screening in primary care: A cluster randomized trial.

Hepatitis C virus (HCV) and HIV are major causes of worldwide disease. We aimed to evaluate the effect of a combined screening programme, which included a risk-assessment questionnaire and rapid tests for point-of-care diagnosis, on screening and new diagnosis rates. This prospective, cluster randomized study was carried out in primary care.

Maraviroc reactivates HIV with potency similar to that of other latency reversing drugs without inducing toxicity in CD8 T cells.

Human immunodeficiency virus (HIV) remains incurable due to latent reservoirs established in non-activated CD4 T cells. Current efforts to achieve a functional cure rely on immunomodulatory strategies focused on enhancing the functions of cytotoxic cells. Implementation of these actions requires a coordinated activation of the viral transcription in latently infected cells so that the reservoir became visible and accessible to cytotoxic cells.
