- People with human immunodeficiency virus (HIV) can sometimes develop thinking and memory problems. These problems can vary widely, from few symptoms to severe problems with memory and concentration. It initially was thought that good HIV treatment could prevent almost all HIV-related memory problems. However, even people with low HIV viral loads can have these problems. It may be caused by HIV affecting the brain and spinal fluid. It is not yet clear why HIV causes these problems and why they may be worse in some people than others. Researchers want to study people with HIV and healthy volunteers to see how HIV may affect people with only small amounts of the virus in their blood.
- To study thinking and memory problems in individuals with HIV that is otherwise controlled with medications.
- Individuals between 18 of age or older whose HIV has been controlled with medications for at least 1 year.
- Healthy volunteers between 18 of age or older.
- Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. A neurological test will also be given. Participants will have a baseline imaging study of the brain.
- Within 12 weeks of the first visit, participants will have a second visit. Additional blood samples will be drawn. Another brain imaging study will be performed.
- Within 8 weeks of the second visit, participants will have a third visit to collect more blood samples. They will also provide spinal fluid samples, either as a single visit or a longer procedure.
- After this visit, participants will return every 12 months for up to 10 years. Blood samples will be collected as needed at these visits. Thinking and memory tests and imaging studies may also be given as needed. Spinal fluid may be collected at one visit a year.
|Condition or disease|
The natural history of neurocognitive impairment in human immunodeficiency virus (HIV)-infected individuals remains poorly understood. While the advent of highly active antiretroviral therapy (HAART) has led to a decreased incidence of the most severe form of HIV associated neurocognitive disorders (HAND), HIV-associated dementia, it does not appear to have impacted overall prevalence of HAND. Existing evidence suggests that the central nervous system (CNS) could be an important reservoir for HIV regardless of cumulative time on treatment. This 20 year multi-institute natural history protocol will identify approximately 500 HIV-infected individuals and 250 healthy volunteers for enrollment in multiple HAND studies at the National Institutes of Health (NIH). Subjects will undergo a screening and evaluation assessment, which will include blood and urine collection, neuropsychological testing, Client Diagnostic Questionnaire (CDQ), and brain magnetic resonance imaging (MRI) with optional lumbar puncture and ophthalmology exam to repeat yearly for up to ten years.
The option to have a lumbar drain is only on the first visit and extended to HIV positive individuals only. Participants will have the option of doing a positron emission tomography/computed tomography (PET/CT) imaging if they have previously had a PET/CT scan under this study. Cerebrospinal fluid (CSF) markers of immune activation, chronic monocyte activation, cytomegalovirus/Epstein-Barr virus (CMV/EBV) infection/reactivation, and neuronal injury will be collected. In addition, HIV viral load and genotype, genetic susceptibility factors and CNS penetration-effectiveness score (CPE) and CSF levels of antiretroviral drugs may be assessed. A repository of cryopreserved biological samples will be developed and used for validation of candidate biomarkers in future studies. Collection and analysis of these data will not only enhance understanding of the CNS as a potential HIV reservoir in virally-controlled individuals but will further define the association among cortical thickness, biomarkers and neurocognitive function in an aging HIV-infected population.

- To characterize in detail the natural course of HAND in subjects with prolonged plasma HIV virologic suppression (<50 copies/mL). [ Time Frame: Annually ]The prevalence of neurocognitive impairment in this cohort will be high despite HIV plasma viremia below the limit of detection (BLD) in the blood as chronic activation may be mediating neuronal damage and result in cognitive impairment.
