Filter by:Little is known about autophagy during HIV infection. Recently, two different teams reported important dysfunctions of autophagy in HIV-infected patients despite sustained suppressive antiretroviral therapy. As altered autophagy is strongly linked to cellular senescence and chronic inflammation, two hallmarks of HIV-infected patients despite long-term suppressive antiretroviral therapy, it is important to improve our knowledge in the area. Our main objective is to determine whether all or part of mononuclear cell subpopulations (CD4+ and CD8+ T lymphocytes, and monocytes) exhibit a defect in autophagy function in a cohort of HIV-infected patients who are virologically-controlled (plasma HIV RNA <50 copies / ml) either spontaneously (i.e. HIV controllers or post-treatment controllers) or after they started antiretroviral therapy at different time points (i.e. at the acute or chronic phases), as compared with a control group (i.e. uninfected healthy blood donors).
The HIV/HEART Aging study (HIVH) is an ongoing, prospective, multicentre trial that was conducted to assess the incidence, the prevalence and the clinical course of cardiovascular diseases (CVD) in HIV-infected patients. The study population includes outpatients from specialized HIV-care units of the German Ruhr region, who were at least 18 years of age, were known to have a HIV-infection and exhibited a stable disease status within 4 weeks before inclusion into the trial. From March 2004 (Pilot phase) to October 2019 (12,5 year Follow-up) 1806 HIV+ patients were recruited in a consecutive manner. The standardised examinations included a targeted assessment of medical history and physical examination. Blood was drawn for comprehensive laboratory tests including HIV specific parameters (CD4 cell count, HIV-1 RNA levels) and cardiovascular items (lipid concentrations, BNP values and renal parameters). Furthermore, non-invasive tests were performed during the initial visit, including additional heart rate and blood pressure measurements, electrocardiogram (ECGs) and transthoracic echocardiography (TTE). Examinations were completed in accordance with previously defined standard operating procedures. CVD were defined as coronary, cerebrovascular, peripheral arterial disease, heart failure or cardiac vitium.
Despite the high burden of respiratory symptoms in the HIV+ population, causes of chronic obstructive pulmonary disease (COPD) in individuals with HIV are poorly understood. Microbial communities present in the lungs or gut could play an important role in COPD via their ability to stimulate inflammation and oxidative stress and by the interactions of microbial and host gene transcription. By exploring the impact of the structure and function of microbial communities on the host in HIV-associated COPD, this project could lead to discovery of novel therapeutics to treat and prevent COPD. Subjects will be 20 HIV+ individuals with COPD (FEV1/FVC <0.70 and FEV1 and DLco<80% predicted) and 20 HIV+ individuals with normal lung function (controls) and 10 HIV negative individuals recruited from our ongoing cohorts. Controls will be matched to the individuals with COPD based on age, gender, pack-years of smoking, ART use, HIV viral suppression, and history of illicit drug use. Bronchoscopy will be performed on all subjects. The investigator will uncover mechanisms that contribute to COPD in HIV+ individuals, which will lead to interventional therapies. For example, the investigators evaluate the impact of bacteria on lung epithelial cell gene expression and inflammation and test ability of anti-inflammatories to alter responses. Identification of other key pathways or microbes could also lead to testing of pro-biotics, post-biotics (bacterial metabolites), or therapy with bacteria genetically modified for desired function or metabolites.
The primary objective of this study is to compare the relative effectiveness of three web-based platforms: social media sites (e.g., Facebook), dating applications [apps] (e.g., Grindr), and informational sites (e.g., Google) to promote self-testing of Human Immunodeficiency Virus (HIV) infection among men who have sex with men (MSM) who are at increased risk of HIV exposure and/or infection. In addition, we will measure Pre-Exposure Prophylaxis (PrEP) uptake and evaluate the degree to which substance use and, separately, the participant's intention to test affect HIV self-testing and PrEP uptake. Through this research, we will also examine how participants' social media use, attitudes on HIV testing, perceptions of sexual risk behavior, medical mistrust, and stigma impact HIV testing and PrEP uptake.
Researchers will conduct a 2-arm pilot randomized controlled trial with HIV-infected index patients recruited from two all-male prisons in Indonesia to assess the acceptability and feasibility of provider-assisted HIV partner notification (provider referral) and examine its potential to increase the number of partners who are tested for HIV and subsequently linked to prevention and treatment services.
Current British HIV Association (BHIVA) guidelines recommend annual cervical screening (with a cervical smear) for women living with HIV (WLWH). NHS guidelines for women in England will, however, change soon. Women will initially be tested for human papilloma virus (HPV), a virus which causes virtually all cervical cancer. Only those who are infected with HPV will then undergo the smear testing. The BHIVA guidelines, however, taking the view that HIV infection (and its ability to weaken the immune system) increases the risk of persistent HPV infection and of cancer in those who are infected, consider safer for all WLWH to go straight to annual smear testing. Most WLWH in the UK are now receiving treatment which protects their immune system - this suggests that less WLWH could be HPV infected. The identification of a group of WLWH who could benefit from less frequent screening could improve quality of life, and allow the NHS to reduce unnecessary tests and costs. A large study is needed to collect robust evidence that would support changes to standard practice. Before investing huge resources, the investigators need to know if a study would be feasible, conducting a pilot study on 70 WLWH aged 25-64, regularly attending clinics for HIV care. Participants will be asked to complete an entry survey and they will undergo routine cervical smears (baseline and after 1 year). At baseline, after six months, and one year women will take their own vaginal swabs for the detection of HR-HPV. An exit questionnaire will be undertaken at the last visit.
The North Carolina Bridge Counselor system is designed to help link out of care HIV positive patients back into HIV care. It has improved initial linkages and patient re-engagement overall, but for a sizable group of patients, the current system has not been effective, leaving a population of hard-to-reach, lost-to-care patients who remain out of care. There is limited understanding of the lived experiences of patients who fall out of HIV care and become recalcitrant to re-engagement because they are difficult to reach and therefore underrepresented in research. Out of care HIV+ patients who have not reengaged in care following the standard of care who chose to enroll in the study will participate in 2 semi-structured interviews and receive a field-based HIV re-engagement and treatment intervention (Project RAMP). Project RAMP will consist of up to 4 visits from an outreach research nurse designed to serve as an "on-ramp" to HIV care. At these visits, the outreach number will counsel on HIV care and treatment and obtain a medical history and labs. Results will be communicated to the participant's clinic provider in an effort to both encourage the patient to return to care and facilitate more rapid antiretroviral therapy (ART) initiation by the clinic provider. The research team will also provide the participant in-person assistance with scheduling a clinic visit. Clinic providers may re-initiate ART prior to the reengagement clinic visit, with adherence support provided by the outreach nurse.
The primary objective of this study is to evaluate the antiviral activity of lenacapavir (formerly GS-6207) administered as an add-on to a failing regimen (functional monotherapy) in people living with HIV (PLWH) with multi-drug resistance (MDR).
The primary objective of this study is to evaluate the effectiveness of a clinical decision support system (CDSS) combined with enhanced patient contact to retain HIV+ patients in care with AIDS Healthcare Foundation. Specifically, the study aims to evaluate the effectiveness of having the patient's primary caregiver (or dedicated case manager) telephone the patient when the patient is identified as a significant risk to loss of follow-up (at-risk patients) based upon pre-defined criteria. The secondary objective Gain a better understanding about the implementation of the study's procedures in clinical practice by evaluating survey responses delivered to participating healthcare providers and AHF staff members engaging with the study's intervention.
To assess the safety of combination immune therapy in HIV-infected participants whose HIV is controlled with ART, by determining the incidence and severity of adverse events.
