About this study
Official title: Immunologic and Inflammatory Factors and Cardiovascular Risk in Patients With HIV Infection or Autoimmune Diseases
This is a longitudinal observational study of HIV-infected patients and HIV-negative control patients that is being conducted to learn more about immunologic factors, inflammation, and cardiovascular risk in patients with HIV infection or in patients with autoimmune disease. The investigators plan to obtain measurement of carotid artery intima media thickness (IMT) using high resolution ultrasound as a noninvasive means for tracking atherosclerotic progression. The investigators will also measure lipid and lipoprotein levels, inflammatory markers, markers of Cytomegalovirus (CMV) infection, thrombotic markers, atherogenic lipoproteins, and markers of immune function. Immunophenotyping will be performed on freshly collected blood and analyzed by flow cytometry to identify activated T-cells, T-cell turnover, proportions of T-cells, and CMV function. HIV-infected patients will have CD4 count and HIV viral load measured in addition. Patients will undergo detailed clinical history including HIV disease, specific HIV medications, comorbid conditions, and health related behaviors. Physical exam and measurements will be obtained to assess for the presence of lipodystrophy. Patients will undergo study visits for ultrasound, blood draw, and interview at 4-12 month intervals for the next 3 years.
Patients will also go assessment of endothelial function, endothelial progenitor cells, arterial stiffness as measured using pulse wave tonometry.

To demonstrate the feasibility of a larger scale investigation of cardiac arrhythmia in HIV positive and negative patients with cardiac disease, the investigators will use 48-hour Holter monitor surveillance to monitor HIV-infected and uninfected patients with a history of myocardial infarction, systolic left ventricular dysfunction, and/or pulmonary artery hypertension for the presence of cardiac arrhythmia.
The FDG PET scan (18F-fluorodeoxyglucose positron emission tomography-computed tomography) will be used to detect and quantify inflammation in the body.
Read the detailed description
This proposal is currently approved by CHR (#H9577-18534-03C, exp date 3/26/04); the purpose of this new application is to split the currently approved protocol into a separate protocol with a separate PI. Data collected and patients seen under the previously approved protocol will be carried over into this new separate protocol. This is a longitudinal observational study of HIV-infected patients and HIV-negative control patients, and individuals with autoimmune diseases. We plan to obtain measurement of carotid artery intima media thickness (IMT) using high resolution ultrasound as a noninvasive means for tracking atherosclerotic progression. In addition, patients will undergo ct scan for coronary calcium and single slice abdominal ct scan to assess visceral fat. We will also measure lipid and lipoprotein levels, inflammatory markers, markers of CMV infection, thrombotic markers, atherogenic lipoproteins, and markers of immune function. Immunophenotyping will be performed on freshly collected blood and analyzed by flow cytometry to identify activated T cells,T cell turnover, proportions of T cells, and CMV function. HIV-infected patients will have CD4 count and HIV viral load measured in addition. Patients will undergo detailed clinical history including HIV disease, specific HIV medications, comorbid conditions, and health related behaviours. Physical exam and measurements will be obtained to assess for the presence of lipodystrophy. Patients will undergo study visits for ultrasound, blood draw, and interview at 4-12 month intervals for the next 3 years. Patients will also go assessment of endothelial function, endothelial progenitor cells, arterial stiffness as measured using pulse wave tonometry. In patients with detectable calcium on CT scan, they will be given the option of obtaining CT angiography. Patients will also undergo testing for peripheral arterial disease using ankle brachial index testing and exercise treadmill testing.

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
carotid intima-media thickness (time frame: 2 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01519141, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Nov 2021.
