HIV-Associated Heart Disease
Cardiovascular DiseasesHeart Diseases3 moreTo develop natural history data regarding the incidence, clinical course, prognosis, and effects of treatment with anti-viral and immunosuppressive agents on HIV-associated heart disease. A second part of the study evaluated a number of possible mechanisms underlying the development of HIV heart disease.
Effectiveness of AIDS Antibody Screening
Acquired Immunodeficiency SyndromeBlood Transfusion1 moreTo determine the effectiveness of efforts to eliminate the human immunodeficiency virus (HIV) from whole blood and blood components in the blood supply.
Prospective Study of HIV Infection in Hemophiliacs
Acquired Immunodeficiency SyndromeHIV Infections7 moreTo examine mechanisms of individual differences in the progression of HIV infection in hemophiliacs.
HIV Diversity and Pathogenesis in Donor-Recipient Clusters
Acquired Immunodeficiency SyndromeBlood Transfusion2 moreTo assess, in donor-recipient clusters, current models of HIV-1 genetic evolution and pathogenesis, based on the sequence diversity displayed by this lentivirus.
Immune Activity Against CVM Retinitis
Acquired Immunodeficiency SyndromeCytomegalovirus Retinitis1 moreThis study will investigate whether medication for cytomegalovirus (CMV) retinitis-a viral infection of the eye-can safely be stopped in HIV-infected patients whose immune function has improved from anti-HIV therapy. Medicines taken to fight CMV infection (ganciclovir, foscarnet, and cidofovir) can cause serious side effects, such as low blood counts and kidney damage. Stopping these medications may, therefore, be beneficial. Patients with HIV infection who develop CVM retinitis usually have very low levels of infection-fighting white blood cells called CD4 cells-less than 50 cells per microliter of blood. New anti-HIV medications have been able to raise CD4 levels and improve immune function in many patients. This study will see if patients with CD4 levels above 150 cells per microliter can fight CVM retinitis without additional anti-CVM drugs. HIV-infected patients with CVM retinitis will have a physical examination and complete eye examination. These tests will be repeated after 2 weeks. If there is no evidence that the CMV infection has progressed, and if it is in a location that is not immediately sight-threatening, anti-CMV medications will be stopped. Patients will be examined every 2 weeks for 3 months and then every 3 weeks for the next 3 months. Patients whose CD4 count has remained above 100 after 6 months will continue to be followed every 4 weeks until the CVM infection becomes active again. At that time, anti-CVM medicines will be re-started. Patients will also have blood and urine samples taken to test for levels of HIV and CMV in the blood and urine, and will be interviewed about their vision and how it affects daily activities.
PrEP Communication Intervention for Female Clients of a Needle Exchange
HIV/AIDSThis study will identify perceptions of PrEP in women who inject drugs (WWIDs) and develop and pilot test a targeted intervention that will be embedded in a large, urban syringe exchange program through an extensive formative evaluation process. Using perceptual mapping, an innovative marketing evaluation technique, WWIDs' PrEP perceptions will be incorporated into messaging in targeted counseling, materials, and text messaging to encourage PrEP adherence. This will then be tested in a pilot Randomized Controlled Trial (RCT) by comparing it to a general PrEP intervention to assess for uptake and adherence to PrEP, as well as improved self-efficacy and lower decisional conflict.
Obstructive Sleep Apnea Endotypes and Impact on Phenotypes of People Living With HIV
Human Immunodeficiency VirusObstructive Sleep ApneaThe investigators seek to understand how the different underlying causes of OSA affect the way people living with HIV (PLWH) experience OSA. The investigators also want to understand how symptoms of obstructive sleep apnea improve with treatment, and if this too, is affected by the underlying cause of OSA in that individual
An Italian Observation of Antiretroviral Treatment in Participants Taking Darunavir/ Cobicistat...
Human Immunodeficiency Virus (HIV)The purpose of this study is to describe the effectiveness of Darunavir/ Cobicistat/ Emtricitabine/ Tenofovir Alafenamide (D/C/F/TAF), measured as virological response at Week 48 as per Food and Drug Administration (FDA) snapshot algorithm through collection of daily practice data in the Italian setting.
Interventions to Improve HIV Antiretroviral Therapy Adherence
Human Immunodeficiency Virus (HIV) InfectionThis study will explore whether financial incentives, reminders, information about HIV/AIDS and its treatment and anti-stigma counseling help improve anti-retroviral therapy (ART) adherence among HIV infected individuals in a resource-limited environment. The interventions will be randomized in the study population in a cross-cutting design, with a control group, a financial incentive treatment group, a reminders treatment group, a treatment group that receives both the financial incentive and reminder interventions. In addition, there will be an information treatment group, a stigma-relieving treatment group and a group that receives both information and stigma-relieving interventions. The primary outcomes of interest for this study will be the adherence to ART, measured by attendance rates at clinic appointments and refill collection rates.
The Incidence and Severity of Drug Interactions Before and After Switching Antiretroviral Therapy...
HIV/AIDSThis study will assess changes in the incidence and severity of drug interactions before and after switching antiretroviral therapy to bictegravir/emtricitabine/tenofovir alafenamide-based regimens in treatment experienced patients living with HIV infection.
