Filter by:Most Veterans living with HIV are 50 years of age or older and can expect to live more than 20 years longer with HIV medication. However, despite this success, Veterans living with HIV are more likely to have age-related diseases and loss of fitness and muscle that place them at increased risk for disability. This is a major priority for the VHA, the largest provider of HIV care in the United States. The goal of this study is to test a circuit exercise program in Veterans living with HIV that is designed to slowdown the aging process. The exercise program will be widely available by Video Teleconferencing (VTEL) and does not require stationary exercise equipment, making it widely accessible. This research will help reach the goal for Veterans to preserve their quality of life and ability to function independently. Novel findings will strengthen strategies to maintain life-long fitness through a personalized exercise prescription.
In summary, in this project the investigators propose to study the proviral DNA genotyping to implement a lower cost and wider than the commercial systems currently in use, in order to analyze all HIV genes that are therapeutic targets of antiretroviral drugs. Using HIV proviral DNA we can obtain information for: HIV-1 Viral Tropism, Mutations associated to Integrase Inhibitors, Mutations associated to Transcriptase reverse Inhibitors, Mutations associated to Protease Inhibitors, and Mutations associated to GP41 Inhibitors. Along with this the investigators propose to validate the proviral DNA as starting material for genotyping which is independent of the patient's viral load and achieve a greater number of patients living with HIV have access to this important test that is essential in monitoring the HIV infection. 3.2 RESEARCH QUESTIONs Is proviral DNA a genetic compartment suitable for carrying out a genotypic resistance test in patients with low or undetectable viral load? Does proviral DNA have the same clinical validity that RNA? 3.3.- HYPOTHESIS A resistance genotyping test carried out by Proviral DNA detects the same mutations associated to resistance that viral RNA. 3.4.- OBJECTIVES: General/Specific General objective Develop a methodology to assess the proviral HIV-1 DNA or RNA as the genetic material for genotyping assays in genes that are targets of pharmacological interest as TR reverse transcriptase and protease (PRO), Integrase or GP41 Inhibitors and HIV tropism. Specific Objectives 1. Carry out genotyping by proviral DNA and compare it with the same genes genotyping performed with viral RNA. 2. Once the correlation between proviral DNA and RNA has shown, standardize a method to use the technique for clinical use in monitoring HIV patients according to each patient's needs. RNA for patients with viral load above 1,000 copies/mL. Proviral DNA for patients with low or undetectable viral load.
Background: Most people with tuberculosis (TB) feel better after starting treatment. But for some people, the opposite happens. They may feel better at first, but then suddenly get worse. This is a paradoxical reaction. Researchers want to better understand what causes this reaction and what happens after someone has it. Objective: To learn about paradoxical reactions to TB treatment. Eligibility: Adults 18 and older diagnosed with confirmed or suspected TB and currently on treatment for at least 2 weeks, with or without signs/symptoms of a paradoxical inflammatory reaction. Design: Participants will be screened with a physical exam and medical history. They will give blood and urine samples. Eligible participants will visit the NIH Clinical Center 3 times over 6 to 18 months. Each visit will take 7 hours to complete; visits may be scheduled over more than 1 day. Participants may have more visits if their TB symptoms change. Participants will give blood, urine, and sputum samples. They will have adverse event assessments. They will have 2 to 3 positron emission tomography/computed tomography (PET/CT) scans. PET/CT scans make pictures of the inside of the body. For this, participants will lie on a table that slides into a donut-shaped scanner. They will get a small amount of radioactive dye through an IV, which is a small plastic tube placed in a vein in the arm using a needle. Participants may have optional apheresis. For this, blood is taken from a needle in one arm. White blood cells are separated from the rest of the blood. The rest of the blood is returned through a needle in the other arm.
This study will examine whether moderate alcohol use in the context of HIV infection exacerbates inflammatory signaling in the immune system and brain. The study will recruit healthy individuals and people living with HIV infection who are otherwise in good health to participate. Participants will complete an experimental protocol that involves controlled alcohol administration and magnetic resonance imaging (MRI). Primary outcomes are plasma biomarkers of inflammation and MRI markers correlated with neuroinflammation. Results will advance understanding of the effects of alcohol use in people living with HIV infection.
This study will utilize a longitudinal study design to better understand the natural history of oncogenic Human Papillomavirus (HPV) infections in Human Immunodeficiency Virus (HIV)-infected and HIV-uninfected Kenyan women, including the potentially modifiable (and non-modifiable) factors that are associated with progression of oncogenic HPV infection to clinical disease, including cervical cancer.
The aim of this study is to characterize in non-viremic HIV-1 patients under antiretroviral therapy an immune activation profile that the investigators have previously shown to be strongly linked to hyperinsulinemia. This characterization will be carried out via 3 different approaches. First, the investigators will analyze the metabolites present in the plasma of patients presenting with the profile of interest. Second, the investigators will study the transcriptome of the peripheral blood mononuclear cells of these patients. Finally, the investigators will search whether some factors released by these cells are able to induce insulin resistance. In addition the ability of the profile of interest to predict an increase in insulinemia over time will be assessed.
Pre-Exposure Prophylaxis (PrEP) is a biomedical strategy consisting of the use of antiretroviral therapy by HIV-seronegative people at high risk of acquiring HIV, to prevent the infection. Many controlled and randomized clinical trials, as well as implementation projects have shown that the use of tenofovir disoproxil (TDF) and emtricitabine (FTC) is both safe and effective in the prevention of HIV infection. However, the administrative situation of PrEP in Spain is anomalous. Unlike in some European countries, PrEP is not available within the National Health System (SNS), although being available for the treatment of HIV infection. In Spain the fixed-dose combination of FTC / TDF is for hospital use only, which requires prescription by HIV specialists exclusively and restricts its dispensation to pharmacy services within the hospital. This limitation in access and the knowledge of its prevention capacity of PrEP by vulnerable population has led them to obtain "generic FTC / TDF" outside the standardized health care system. According to a survey conducted in Europe to characterize MSM users of PrEP carried out in 2016, 5% of PrEP users had acquired it on their own. Of these 70% stated they were not included in any regular follow-up program while using the medication. Despite the growing demand, there are no health programs (including information, counseling, systematic screening for sexually transmissible infection (STI), etc.) aimed at meeting the health care needs of those who already use or wish to use PrEP, neither by public nor private healthcare providers. This type of service is especially necessary when considering that, among PrEP users, one may have already an established HIV infection, theoretical increase of other STI and a lack of monitoring kidney functions.. BCN Checkpoint is a community center since 2006 for the detection of HIV and other STI aimed at gay men, other men who have sex with men (MSM) and transgender women (TGW), which has shown high efficiency in HIV screening and fast referral to standard HIV care and treatment.. In 2017 the organization opened BCN PrEP·Point, a community centre with the goal to provide information, to conduct clinical trials and clinical monitoring of informal PrEP use. For this reason, it is presented here the protocol of the SeguiPrEP study, prospective, longitudinal study of health care in the community environment, to MSM and TGW, users of informal PrEP, based on point-of-care testing technology.
This is a one year study to develop and test a culturally-tailored, web-based cognitive behavioral stress management (CBSM) intervention for Latino sexual minority men living with both HIV and cancer. Sexual minority Latino men living with HIV and cancer experience a variety of health disparities related to their diagnoses, including higher distress. The project will be a pilot randomized trial, comparing culturally-tailored CBSM to standard CBSM for dually-diagnosed participants. The project will use a community-based participatory research approach, and the investigators have included (and will continue to include) LGBT-serving community partners in all phases of the research from study design to implementation and dissemination of findings. The proposed study will aid in attenuating health disparities among Latino sexual minority men living with HIV and cancer.
B-HAPPY is an implementation project to study the process by which pre-exposure prophylaxis (PrEP) is introduced and integrated into a specific international health system facing high rates of HIV incidence among men who have sex with men. The study will use a stepped wedge design to compare implementation outcomes across eight municipalities in Yunnan, China.
The PRINCESSE study will implement a comprehensive package of services in sexual and reproductive health for female sex workers in the region of San Pedro in Cote d'Ivoire, including screening, prevention and treatment for HIV, viral hepatitis B, sexually transmitted infections and family planning. All services will be available in mobiles clinics operating on prostitution sites and organized for a chronic follow-up of participants.
