Active clinical trials for "HIV Seropositivity"

To determine the safety and immunogenicity of vaccinia-derived HIV-1 recombinant envelope glycoprotein (gp160) in asymptomatic HIV-infected adult volunteers. To compare safety and immunogenicity of two different schedules of gp160 administration. To examine the effects of gp160 and hepatitis B vaccine (Engerix-B) on various markers of viral load and on selected immune parameters. Potentiation of a patient's immune response to HIV might possibly prolong the period of clinical latency and protect the patient indefinitely. Preliminary results from a study of Immuno-AG recombinant gp160 vaccine in healthy volunteers not infected with HIV suggest that the vaccine is safe and produces antibodies against the virus. Because another previous study failed to demonstrate a specific anti-HIV response in patients injected with a recombinant vaccinia virus containing HIV-1 genes, this study is also testing the immunotherapeutic role of other immunizations (such as hepatitis B vaccination) that would be expected to induce a nonspecific immune response in HIV-infected persons.

To provide information on the response of HIV infected, neurosyphilis patients to the currently recommended treatment for neurosyphilis; to determine whether possible co-infection with both HIV and syphilis makes more difficult the diagnosis of syphilis; to explore the usefulness of an alternative treatment which, if effective, would permit outpatient treatment for neurosyphilis that until now required prolonged hospitalization. Studies suggest that syphilis treatment failures may be more common in HIV infected patients than in patients without HIV infection and that treatment failures occur due to and/or are displayed as central nervous system (CNS) involvement. Very little is known about the best treatment course for neurosyphilis in patients who are also infected with HIV.

This study will provide data on the switch from a protease inhibitor or efavirenz to the new formulation of raltegravir (RAL) dosed once daily. The study group consists of patients with metabolic risk factors and co-morbidities, in need of optimization of their current ART to minimize the drug-related metabolic side effects as standard of care. The primary objective of this study is to investigate whether switching a protease inhibitor (PI) or efavirenz to raltegravir once daily reduces liver fat in patients who are overweight or obese and have at least one metabolic syndrome component. For this purpose, the liver fat content will be analyzed using the proton magnetic resonance spectroscopy. In addition, the aim is to clarify the change in the body composition and metabolism in this study group. For this purpose the visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) volumes will be measured and subcutaneous tissue samples will be collected for future analyses of adipose tissue function.

The present study focuses on adult persons living with HIV in the New York City and Newark, New Jersey metropolitan areas who are not highly adherent to HIV medication and who do not evidence undetectable HIV viral load (the ultimate goal of HIV treatment). Those who have not decided whether they wish to take HIV medications are invited to enroll. The study uses technology, is grounded in principles of behavioral economics, and uses the multiphase optimization strategy (MOST) to examine the acceptability, feasibility, and evidence of efficacy of three intervention components. The components are intended to increase rates of HIV viral suppression in the sample. The three components are: prizes for viral suppression (fixed compensation [$275] or lottery prizes [up to $500]), text messages and quiz questions that generate points to earn prizes (to foster engagement), and counseling sessions grounded in the motivational interviewing approach to help participants articulate goals with respect to health and viral suppression, identify and resolve barriers to HIV medication use, and build motivation for viral suppression. Participants are assessed at baseline and then 5- and 8-months later.

The purpose of this study is to evaluate the safety and efficacy of Zadaxin® in the treatment of HIV-positive patients with immune reconstitution disorders. Researchers previously used Zadaxin® (Thymosin α-1, Tα1) as an immune adjuvant for people infected with HIV-1 and found that Tα1 and Interferon-α (IFN-α) have a synergistic effect in immune enhancement. In addition, studies have found that the triple combination of Tα1, IFN-α and Zidovudine has better tolerability, safety and efficacy. After treatment, patients have lower HIV RNA and more stable high CD4+ T cell counts. In addition, extensive studies on the administration of Tα1 in thymectomized mice have demonstrated its ability to promote immune reconstitution. The researchers hypothesized that Zadaxin® has a better therapeutic effect on HIV-positive patients with immune reconstitution disorders, can increase the CD4+T cell count, reduce the viral load, and has better safety.

Specific Aim: To conduct a randomized, placebo-controlled trial of extended release-naltrexone (XR-NTX) among Human Immunodeficiency Virus (HIV) infected prisoners meeting Diagnostic Statistical Manual IV (DSM-IV) criteria for opioid dependence who are transitioning from the structure of a correctional setting to the community. Hypotheses: i. XR-NTX will result in improved HIV clinical outcomes, including lower changes in HIV-1 RNA levels, higher CD4 counts and higher rates of retention in care. ii. XR-NTX will result in improved opioid treatment outcomes, including longer time to opioid relapse, lower addiction severity and lower craving for opioid. iii. XR-NTX will result in reduced drug- and sex-related HIV risk behaviors compared to the control group. iv. XR-NTX will result in decreased rates of reincarceration after 12 months of release to the community.

The purpose of this study is to determine whether the long-term administration of statins may benefit the clinical and immunological evolution in HIV-1-infected individuals before the use of antiretroviral therapy is required.

Children living with HIV from sub-Saharan Africa often present with severe malnutrition. In severe malnutrition, metabolic and/or gut structural derangement may lead to inadequate antiretroviral (ARV) absorption and/or erratic drug levels. The greater surface area to weight ratio in severely malnourished children could also place them at higher risk of under dosing compared to children with mild to moderate malnutrition. However, limited data are available on the pharmacokinetics of ARVs in severely malnourished children. This study addressed this critical gap in knowledge by evaluating the PK of zidovudine (ZDV), lamivudine (3TC), and lopinavir/ritonavir (LPV/r) in severely malnourished children living with HIV, compared to children with normal nutrition to mild malnutrition living with HIV.

The number of late middle-age and older adults living with HIV/AIDS in the U.S. continues to rise due largely to better clinical care and the improved efficacy of highly active antiretroviral therapy that has extended the lives of many HIV-positive persons an increase in the number of new HIV infections in older persons. This study tested the efficacy of 1- and 4-session telephone-administered behavioral sexual risk reduction interventions for HIV-positive adults 45-plus years of age who engage in risky sexual behaviors.

To compare the effect of AS-101 to that of placebo on clinical efficacy and immunologic function in HIV positive patients with advanced disease. To compare the effect of AS-101 to that of placebo on occurrence of disease progression in HIV positive patients with advanced disease as defined by: (1) development of new diagnostically confirmed major opportunistic infection(s); or (2) development of AIDS-related dementia. To compare the effect of zidovudine (AZT) plus AS-101 versus AZT alone (placebo arm) on clinical efficacy and immunologic function in patients who require anti-viral therapy due to disease progression. Garlic capsules will be given to all study participants to mask the obvious garlic odor of AS-101.
