Filter by:exercise and physical activity can have an anti-inflammatory effect, while there is evidence that a sedentary lifestyle could be the basis for the development of systemic inflammation and increased cardiovascular risk. The primary objective is to assess whether regular physical activity is able to induce a decrease in systemic immune-activation in HIV positive patients.
Background: Human immunodeficiency virus (HIV) attacks the immune system. Some people with HIV have a low CD4+ T-cell count despite taking antiviral medicines that control HIV replication. These cells fight disease, so a low count makes it easier for people to become sick. Researchers want to see if a new drug can improve the immune system, including T cells. The drug is called pembrolizumab Objective: To see if pembrolizumab is safe to use in people with HIV who have a low CD4+ T cell count despite taking medcines that control HIV replication, and to see if it strengthens the immune system. Eligibility: People age 18 years or older with HIV who are taking antiretroviral drugs as treatment, have blood HIV levels below detection limits of commercial assays, and have a low CD4+ T-cell count (below 350 cells/mm3). Design: Participants will be screened with: Medical history Physical exam Heart, blood, and urine tests Sexually active participants must use 2 kinds of birth control. Participants will have leukapheresis. Blood will be removed through a needle in one arm. A machine will remove white blood cells. The rest of the blood will be returned into the other arm. Participants will have a baseline visit. They will have blood tests. They may have a pregnancy test. A needle will insert a thin plastic tube (IV) into an arm vein. The participants will get the study drug or a placebo through the IV for 30 minutes. They will be watched for a couple hours after. Participants will have 11 follow-up visits over the next 48 weeks. They will have a physical exam, vital signs, medical review, and blood tests. Participants may have another leukapheresis. Participants will be called every 12 weeks after their last follow-up visit to talk about how they feel and their health. Participation ends after the week 96 phone call. ...
Phase 3b, single arm, simplification study with dual therapy including Lamivudine (300 mg QD) plus Raltegravir (1200 mg QD) in virologically suppressed HIV-1 infected patients experiencing inconvenience, toxicity, negative impact on comorbidities or risk of drug-drug interactions with their current regimen.
The objective of the study is to evaluate the effectiveness of a HIV risk assessment tool to promote HIV testing and to reduce high risk sexual behaviors among men who have sex with men (MSM). It hypothesizes that the social media-based HIV risk assessment tool can increase 20% HIV testing proportion during the six months follow-up period.
Phase 3b, single arm, single site simplification study of HIV-1 infected patients with virological suppression under the combination of Lamivudine (150 mg BID) plus Raltegravir (400 mg BID) switching to Lamivudine (300 mg QD) plus Raltegravir (1200 mg QD): Roll-over study of the RALAM clinical trial (NCT02284035)
Background: A person s genome is the collection of all their genes. A gene instructs individual cells to make proteins. Proteins are involved in all of our body s chemical processes. Genome sequencing allows researchers to find variations in genes. Some of these are normal and are not known to cause disease. Some variants are known to cause or affect diseases like cancer. Researchers want to study genetic variants in people with cancer who also have an immunologic disease like HIV. Objective: To study the biology of cancer in order to improve ways to prevent, detect, and treat it. Eligibility: Adults at least 18 years old with certain cancers and/or immunodeficiencies Design: Participants will be screened with medical history, physical exam, and lab tests. Participants will give samples of one or more tissue type. They may give blood or urine samples. Researchers may get samples of tissue when participants have surgery or when the participants are on other protocols in the NCI. Participants may have a procedure to have tissue samples removed. Researchers may collect data from participant medical records. Researchers will compare the genes in a participant s cancer tissue to their normal tissue. They may use the tissue cells to grow new cells in a lab. Participants may be contacted about the results. The samples will be stored for future research. No personal data will be kept with them. ...
HIV infection is now a chronic disease in countries where antiretroviral treatments (ART) are largely available. Long-term follow-up is required to describe and understand the evolution of morbidities and complications as well as new treatments side effects. The main objective of the cohort is to describe and study the evolution of HIV infection in ART-treated individuals.
This is a prospective cohort study designed to define the impact of HIV infection and antiretroviral therapy (ART) on young adults with perinatal HIV infection as they transition to adulthood.
Phase IV, Single-Arm, Open-Label Study Evaluating Bone Mineral Density in HIV-1-Infected Adults ≥50 Years Old Switching from EVG/COBI/FTC/TAF (Genvoya) or EVG/COBI/FTC/TDF (Stribild) to ABC/DTG/3TC (Triumeq)
Despite decades of traditional prevention efforts based on behavior change and condom use, Ontario has seen over 700 new HIV infections annually over the past 10 years. Post-exposure prophylaxis (PEP) is one such approach, in which uninfected persons use 28 days of antiretroviral medications (ARVs) shortly after an HIV exposure to minimize the risk of acquiring HIV. PEP is highly efficacious, is considered a standard of care intervention based on medical and ethical grounds, and is supported by treatment guidelines. Yet several implementation challenges have limited its clinical and public health impact in Ontario, where no formal PEP policy exists. Our proposal seeks to optimize two aspects of delivering PEP for sexual exposures (nPEP). Results will inform the development of a standardized approach to nPEP both province-wide and elsewhere. Thus study has pragmatic, multicenter randomized controlled trial using a 2x2 factorial design to determine whether the proportion of nPEP patients that successfully complete follow-up: 1. is higher among those receiving mobile phone-based text messaging support than among those receiving standard care; and 2. is non-inferior among those receiving care from a sexual health clinic nurse compared to those receiving hospital-based physician care. The prospective, randomized, non-blinded, 2x2 factorial trial that will enroll 318 study participants in Toronto. In Intervention A, we will randomize half of study participants to a text messaging support service ('WelTel'), in which a trained, community-based counselor provides standardized weekly 'check-in' messages during their 12-week course of PEP follow-up. The other half will receive standard care, which does not include any form of active outreach or reminders outside of scheduled appointments. In Intervention B, we will randomize half of participants to receive nurse-led care for PEP follow-up at a local sexual health clinic; the other half will receive standard care by a hospital-based ID physician. The specific activities for each follow-up visit will be clearly defined in a medical directive. In keeping with Ontario legislation on medical directives, nurses will review cases with their authorizing physician or nurse practitioner on a routine basis.
