Background: \- 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. Objectives: \- To study thinking and memory problems in individuals with HIV that is otherwise controlled with medications. Eligibility: * 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. Design: * 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....
NCT01737047
The purpose of this study is to identify medical conditions that may cause particular problems to individuals receiving care for HIV infection over the age of 50. In addition, as the effects and potentially the side effects, of HIV medication may change with age, this study will also investigate the association between age and differing effects of antiretroviral therapies such as treatment outcomes, side effects and the levels of drugs in blood. Results from this study may inform future HIV treatment guidelines on how individuals with HIV infection are monitored. The results may also assist in the design of future studies for the treatment of diseases associated with ageing.

The investigators propose to prospectively study the difference in treatment (CTRT) completion and toxicities between HIV positive and HIV negative women in India with locally advanced cervical cancer receiving CTRT.
NCT06971445
This clinical trial aims to determine the effect of PUFA-n3 supplementation on birth weight, gestational length, and plasma inflammatory markers in pregnant women with HIV who are on antiretroviral therapy. The key questions this study seeks to answer are: 1. Will the neonates of HIV-positive women who received 1280 mg of PUFA-n3 supplementation during pregnancy have higher birth weights and longer gestation periods compared to the neonates of HIV-positive women who received a placebo? 2. Will the inflammatory markers in HIV-positive women who received 1280 mg of PUFA-n3 during pregnancy differ from those of HIV-positive women who received a placebo? Researchers will compare the effects of 1280 mg of PUFA-n3 supplementation against a placebo (olive oil) to determine if the supplement can increase birth weight, gestational length, and attenuate the inflammation. Participants in the study will: * Take a prenatal multivitamin that includes 300 mg of PUFA-n3 * Take either 1280 mg of PUFA-n3 or a placebo daily for 8 weeks, starting from a gestational age of 20-29 weeks. * Visit the hospital at the beginning of the study and again 8 weeks later for blood sampling. Additionally, they will have follow-up visits every 2 weeks to monitor gestational weight gain and dietary intake. * Keep a diary to register their supplement intake and record any side effects.

NCT01941121
This is a CCTG sponsored project to determine if those recently screened for HIV would accept assistance to be linked into appropriate health services. After receiving their HIV results, high-risk individuals who test negative will have an option to be linked into a study that offers them Pre-exposure Prophylaxis (PrEP), and individuals who test positive will have an option to be linked into care. If they accept, tested individuals will be in contact with an ALERT specialist that will help facilitate their linkage. The study's primary analysis will analyze how many HIV screened individuals accept the ALERT specialist assistance.

By the end of 1999, it was estimated that 1.2 million children were living with HIV infection. During 1999 alone, 600,000 children were newly infected with HIV, mostly in less-developed countries. Most HIV-infected children are infected by transmission from mother to child during pregnancy, at birth, or through breast milk. Antiretroviral medications, cesarean section before rupture of membranes, and avoidance of breastfeeding are ways to reduce the risk of transmission. This study will determine mother-to-child transmission rates and the effects on infants of exposure to antiretroviral medications and mode of delivery. Approximately 180 to 240 HIV-infected pregnant women in Mexico and Argentina will be enrolled during the first year of this 5-year study. HIV-infected women will be evaluated during pregnancy, during delivery, and 6 months after delivery. At each visit, a history will be taken and physical examination given; blood will be collected for laboratory tests. HIV-exposed infants will be evaluated through 6 months of age. At each of 2 visits, a history will be taken and physical examination given; blood will be collected for laboratory tests; and growth will be assessed.
NCT01152684
The goal of The investigators community-based participatory research study is to identify the nature and extent of complementary and alternative medicine (CAM) use among HIV-positive Latinos on the San Diego/Tijuana border. CAM use among US Latinos living with HIV is associated with delayed utilization of and poor adherence to antiretroviral therapies (ARVs) that may exacerbate health disparities in HIV care access and health outcomes. This study will lead to development of culturally-effective interventions to improve access and adherence to HIV care in Latinos who face health disparities. The investigators hypothesis is that greater use of CAM will be observed among HIV-positive Latinos who report a) crossing the U.S. border more frequently, and b) having migrated to Tijuana or San Diego (e.g. from southern Mexico). The investigators also hypothesize that compared to HIV-positive Latinos who report using herbal CAM, those who do not use herbal CAM are more likely to be receiving ARVs and report higher levels of adherence to ARVs; Compared to HIV-positive Latinos who do not attend religious services regularly, those who attend religious services regularly are more likely to be receiving ARV; Compared to HIV- positive Latinos who report experiencing HIV related stigma, those who do not report experiencing HIV-related stigma are significantly more likely to be receiving ARVs.

NCT01904201
The health of the immune system in HIV infected people is currently determined from a blood test measuring the number of cluster of differentiation 4 (CD4) T lymphocytes. These cells play a critical role in an immune response. Studies have shown that low numbers (below the normal range) of CD4 T lymphocytes indicates a defect in the immune system. Conversely, the number of CD4 T lymphocytes within the normal range generally indicates a normal immune system. When a person is infected with HIV the CD4 T lymphocytes are attacked and destroyed and the numbers decline meaning that the immune system can no longer effectively protect the body from infection or cancers. However, when the HIV infected person is successfully treated with Highly Active Antiretroviral Therapy (HAART) the CD4 T lymphocytes numbers increase and may end up in the normal range but the immune system may still not function properly as a number of these cells are incapable of functioning properly. It would be interesting to know how functional the immune system is rather than the number of cells. For this, the QuantiFERON® Monitor (QFM or CST007) test is an experimental diagnostic test used in this study to measure the immune function from people infected with HIV. The objective of this study is to evaluate the usefulness of the QFM test in HIV infected people compared with uninfected people by measuring the function of the immune system. The QFM test measures interferon-gamma released in the plasma following incubation of heparinised whole blood with a combination of stimulants. As immune function is directly influenced by cells with actively replicating HIV an additional research test called the HIV Reservoir Test will be included to better understand the level of immune function in each study subject. How long will it take? One visit for about 1 hour with Dr. Gatpolintan and his Clinical Study Coordinator to answer questions, then about 10 minutes for a blood draw (nine blocks from Dr. Gatpolintan' office). Study outcome measures (Correlation between QFM and CD4 counts and CD4/CD8 ratios) will be assessed, including data presentation, within an average period of 1 year after study subject enrollment.
