HIV Infection And Evolvement of Atherosclerotic Plaque
Coronary Artery DiseaseAtherosclerosis4 moreIn a prospective multi-center observational study, 200 HIV-infected patients treated with antiretroviral treatment (ART) and who suffered from coronary artery disease (CAD) will be enrolled. Blood samples for biological parameters will be collected with all participants: lipid profile and markers of systemic inflammation specific for HIV-infection (lipopolysaccharide-binding protein; cytokines: IL-1β, IL-6, IL-8, IL-10, TNF -α, INF-γ, INF-α; procalcitonin; inflammatory hsCRP). All of them will undergo functional testing (Echo, CMR both at rest and stress if necessary) and invasive imaging with QCA, FFR, QFR, OCT, IVUS, VH-IVUS, NIRS. Patients will be treated according to the current and previous recommendations. Both medical treatment and percutaneous transluminal coronary angioplasty (PTCA) with or without stenting will be done. Collected data will be analyzed: correlation between ART, blood test results, coronary angiography results, including performed PTCA, history of myocardial infarctions, and other cardiovascular events. The follow-up period will achieve 12 months prospectively with collected clinical events and imaging outcomes which will be determined at the baseline and 12-month follow-up. The independent ethics expertise will be provided by the Central Clinical Hospital of the Russian Academy of Sciences (Moscow, Russia). The monitoring of the clinical data with imaging will be provided by The Ethics Board of Central Clinical Hospital of the Russian Academy of Sciences.

Village doctors will be responsible for sending the HIV-related health education information to the participants. The aim of this study is to develop a generalizable, effective, acceptable, and convenient mobile-based information intervention model to improve HIV-related knowledge, attitudes, practices, and health outcomes in poverty-stricken areas in China and measure the impact of incentive policies on the work of village doctors in Liangshan, China.

A Global Record of Patients With Anal Squamous Cell Carcinoma With and Without HIV Infection
Anal Squamous Cell CarcinomaHIV InfectionsDue to the scarcity of data on prognostic and predictive influence on CCA, epidemiological studies evaluating these factors need to be developed in patients with CCA. Therefore, the investigators want to evaluate the profile of patients in the real world and from various parts of the world, describing prognostic factors such as CD4 dosage, time of HIV infection, evaluation of viral load, diagnosis of AIDS, geographic region of diagnosis and treatment, clinical staging, medications concomitant with QRT (risk of drug interactions), comorbidities (possible impact on dose-intensity), use of HAART, time of use of HAART, radiotherapy modality (conventional 3D vs Modulated Beam Intensity [IMRT], response to Nigro vs CTII regimens, as well as comparing clinical outcomes with patients without HIV infection.

Measuring Adverse Pregnancy and Newborn Congenital Outcomes
HIV/AIDSPregnancy Related2 moreThe purpose of this study is to develop a pharmacovigilance (PV) surveillance program to monitor adverse pregnancy and infant outcomes, including the presence of congenital abnormalities, among HIV-positive and HIV-negative women and their infants at clinical sites affiliated with the International Epidemiology Databases to Evaluate consortium (IeDEA).

Establish and Characterize an Acute HIV Infection Cohort in a High Risk Population
Acute HIV InfectionTo describe clinical, immunological, and virological characteristics of persons with acute HIV infection To describe demographics and behavioral risk factors for those identified with acute HIV infection To describe neurocognitive function and neuroimaging findings in acute HIV infection as well as describe immune response, HIV-1 genotypes and sequences in the cerebrospinal fluid. To describe the number and characteristics of sexual contacts To describe the willingness of acute HIV-infected subjects to allow the tracking of their sexual contacts for voluntary HIV counseling and testing (VCT) To describe immune response, HIV-1 genotypes and sequences in the genital compartment To describe T cell depletion in the gut mucosa in acute HIV infection and describe the changes in gut T cell during follow up To archive samples for future investigations including determination of viral evolution, and cell-mediated and humoral immune responses in peripheral blood and mucosal compartments

Molecular Characterization of Viral-associated Tumors, Tumors Occurring in the Setting of HIV or...
Human Immunodeficiency VirusCastleman's Disease2 moreBackground: A person s genome is the collection of all their genes. A gene instructs individual cells to make proteins. Proteins are involved in all of our body s chemical processes. Genome sequencing allows researchers to find variations in genes. Some of these are normal and are not known to cause disease. Some variants are known to cause or affect diseases like cancer. Researchers want to study genetic variants in people with cancer who also have an immunologic disease like HIV. Objective: To study the biology of cancer in order to improve ways to prevent, detect, and treat it. Eligibility: Adults at least 18 years old with certain cancers and/or immunodeficiencies Design: Participants will be screened with medical history, physical exam, and lab tests. Participants will give samples of one or more tissue type. They may give blood or urine samples. Researchers may get samples of tissue when participants have surgery or when the participants are on other protocols in the NCI. Participants may have a procedure to have tissue samples removed. Researchers may collect data from participant medical records. Researchers will compare the genes in a participant s cancer tissue to their normal tissue. They may use the tissue cells to grow new cells in a lab. Participants may be contacted about the results. The samples will be stored for future research. No personal data will be kept with them. ...

Trans People Living With HIV Throughout Europe
HIV InfectionsGender Identity1 moreThe project will study a European cohort of individuals identifying themselves as transgender or non-binary and living with HIV. The study will collect both qualitative data on this cohort and clinical data over an 18 month period. The study will investigate the success of HIV treatment for this cohort through the primary outcome measure of HIV viral load recorded in routine blood tests. The results from this study will assist in informing future HIV treatment guidelines on the monitoring of HIV infection in transgender and non-binary individuals and assisting in the design of future interventional studies within this population.

HIV Indicator Diseases in Hospital and Primary Care
HIV InfectionsPrimary Health Care18 morePatients are frequently evaluated by physicians for medical work-up of HIV indicator conditions in hospital and in primary care at the general practitioner. Testing for HIV is indicated with HIV indicator disorder but often omitted in clinical work-up. Besides the fact that HIV testing is forgotten, there are other reasons such as an underestimation of the risk of HIV in the event of indicator disorders, stigma and difficulties in discussing the test with a patient. Also and more relevant for primary care than for the hospital, practical challenges can exist for a patient to go to a laboratory, or costs are a hurdle. This project focuses on improving HIV indicator condition driven testing in different settings of the HIV epidemic, initially in the Netherlands as low HIV prevalence setting followed by an assessment of its benefit in different international settings. A specific focus will also be on the Rotterdam area in the Netherlands which has a high prevalence of undiagnosed HIV in the Netherlands. The ultimate aim is to decrease the number of undiagnosed HIV in populations, improve the 90-90-90 HIV cascade of care goals particularly its first pillar, and to help supporting the UNAIDS goal to end HIV/AIDS
