HIV Infection And Evolvement of Atherosclerotic Plaque

In 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-1?, IL-6, IL-8, IL-10, TNF -?, INF-?, INF-?; 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.

Diagnostic Accuracy of CAD4TB and C-reactive Protein Assay as Triage Tests for Pulmonary Tuberculosis

In the TB TRIAGE+ ACCURACY study, the accuracy of the following products will be determined: CAD4TB (Delft Imaging System, NL), a digital chest x-ray analysis software Afinion CRP assay (Alere Afinion, USA), which detects a cytokine induced acute phase protein CAD4TB and the C-reactive protein assay are two tests with great potential of becoming a triage test for the diagnosis of tuberculosis (TB). These potential triage tests for TB are intended to serve as rule-out tests with a high sensitivity and negative predictive value. Before impact and cost-effectiveness of new TB triage tests for intensified active case finding can be determined, the diagnostic test accuracy needs to be assessed in comparison to confirmatory reference tests. This accuracy study will define cut-off values for CAD4TB as well as for the Afinion CRP assay to be used in a future cluster-randomised trial on impact and cost-effectiveness of TB triage strategies for intensified active case finding in Lesotho and KwaZulu-Natal, South Africa. A sub-study (detailed in a separate study protocol), hereafter called AHD-FEASIBILITY, explores the feasibility of implementing a series of point-of-care tests, including the new VISITECT CD4 Advanced Disease Test (Omega Diagnostics, UK) as part of the WHO-recommended advanced HIV Disease care package in the context of community-based HIV/TB campaigns. Due to the coinciding pandemics and the overlapping symptoms of TB and COVID-19, it is critical to test for SARS-Cov-2 infections in the study population. In addition, this study will contribute to the evaluation of a novel SARS-Cov-2 antigen rapid diagnostic test (from the diagnostic pipeline of FIND) and CAD4COVID, a digital chest x-ray analysis software (Delft Imaging System, NL) in combination with differential white blood cell count.

Safety and Survival of Genetically Modified White Blood Cells in HIV-infected Twins The Gemini Study

This study will consolidate under one umbrella protocol all NIH studies of the safety and survival of gene-modified lymphocytes in HIV-infected twins. The major purposes of the current study are to: place subjects from the various identical twin cell transfer/gene therapy studies on a single, more uniform schedule of visits; examine the long-term safety of apheresis procedures in non-HIV-infected lymphocyte donor twins; examine the long-term safety of lymphocytes in HIV-infected lymphocyte recipient twins. Identical twins enrolled in NIH protocols 93-I-0110, 94-I-0206, 96-HG-0051, and 97-I-0165 involving the transfer of lymphocytes for the treatment of HIV infection are eligible to continue their research participation under the current protocol, 02-I-0080. Participants will not undergo any additional research procedures in this study. They will continue to take their antiretroviral therapy and will be followed at least once a year, or more often if medically indicated, with a medical history, physical examination and blood tests for routine studies and to determine the number of lymphocytes in the blood. Recipient twins will also have blood levels of gene-modified lymphocytes checked. Recipient twins will have some blood stored for RCR (replication competent retrovirus) testing, should it become necessary. A special virus was used to insert genes into the donated lymphocytes and, although the virus was rendered incapable of growing in the body, a theoretical risk exists that the virus could mix with other viruses and possibly begin growing or reproducing. If a participant subsequently develops medical problems, the stored blood samples can be checked for RCR to see if it may be a cause of the problem.
