NCT ID: NCT00365729 Recruiting - HIV Infections Clinical Trials

Viral Load Determination and Biomarkers of High Risk Human Papillomavirus (HPV) - Types in HIV-positive Men

Start date: October 2003
Phase: N/A
Study type: Observational

Human papillomavirus (HPV)-infection belongs to the most common sexually transmitted diseases worldwide. HIV-infected men having sex with men (MSM) are strongly associated with a higher prevalence of genital HPV-infection, a higher incidence of anal intraepithelial neoplasia (AIN), and, consecutively, an increased risk for anal cancer. Since the introduction of highly active antiretroviral therapy (HAART), the incidence of several viral-associated neoplasias has significantly fallen in HIV-infected individuals. At the beginning of the era of HAART, a justified hope existed that genitoanal HPV-related neoplasias would also decrease based on the success of HAART-induced immune restoration. However, HAART seems to have only a small impact on the natural history of AIN as observed in a cohort of HIV-positive MSM before and after the initiation of HAART. As AIN and cancer precursor lesions of the cervix, cervical intraepithelial neoplasia, share distinct clinical similarities, cytologic smear testing for AIN has been recommended to detect and treat early lesions. Thus, this prospective study mainly focuses on the predictive value of HPV-DNA load for the development and clinical progression of AIN in HIV-infected MSM. Moreover, the course of HPV viral load under therapy for anal intraepithelial neoplasia, e.g. topical treatment with imiquimod, will be evaluated. Additionally, immunohistochemical determination of several proliferative biomarkers, as well as cytokines, will be performed.

NCT ID: NCT00306410 Recruiting - HIV Infections Clinical Trials

The Prevalence of Vitamin D Deficiency and Effects of Vitamin D Supplementation in HIV-1 Infected Patients

Start date: January 2006
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine the effect of normalization of vitamin D levels on bone density, immune and adipocyte function in HIV1-seropositive patients.

NCT ID: NCT00285441 Recruiting - HIV Infections Clinical Trials

Identification of Cytokine Profiles and T Cell Subsets Among Immunosuppressed Patients at Risk of Developing Active Tuberculosis

Start date: November 2005
Phase: N/A
Study type: Observational

The purpose of this study is to identify differences in TB specific immune responses among immunosuppressed patients latently infected with TB and patients with active TB.

NCT ID: NCT00273403 Recruiting - HIV Infections Clinical Trials

Outcome Evaluation of Minority AIDS Initiative Programs in the New York EMA

Start date: November 1999
Phase: N/A
Study type: Interventional

This outcome evaluation effort provides the opportunity to learn what programmatic approaches effectively address two of the most difficult hurdles in HIV health services delivery: (1) getting people who would benefit from health care to use it and (2) getting people who do use health care to do so more consistently and effectively. The New York HIV Planning Council (through MHRA) has funded 23 agencies to achieve these objectives for people of color with HIV disease.

NCT ID: NCT00241930 Recruiting - HIV Infections Clinical Trials

Integrating Buprenorphine Into HIV Treatment

Start date: September 2005
Phase: Phase 4
Study type: Interventional

We hypothesize that integrating drug treatment into HIV treatment will improve HIV outcomes as well as drug treatment outcomes in heroin users. This study will test this hypothesis by randomizing patients to two groups. The first group will receive HIV treatment and buprenorphine treatment contemporaneously at their HIV clinic. The second group will receive HIV treatment at their HIV clinic, and go to another facility to receive buprenorphine treatment services. We will look at HIV outcomes such as CD4 counts, HIV viral loads, and attendance at appointments and drug treatment outcomes such as receipt of buprenorphine and urine toxicology testing.

NCT ID: NCT00239733 Recruiting - HIV Infections Clinical Trials

Anti-D for Treating Thrombocytopenia in Adults Infected With Hepatitis C Virus With or Without HIV Co-Infection

Start date: March 2005
Phase: N/A
Study type: Interventional

Thrombocytopenia occurs when a person's blood has a decreased number of platelets, which are cells involved in blood clotting. This condition may lead to uncontrolled bleeding and can be fatal. Thrombocytopenia commonly occurs with hepatitis C virus (HCV) infection or as a result of standard HCV treatment. Anti-D is an antibody approved by the Food and Drug Administration (FDA) for the treatment of HIV-related thrombocytopenia. The purpose of this study is to determine the safety and effectiveness of intravenous anti-D for the treatment of thrombocytopenia in patients with HCV infection who are starting or already undergoing treatment with peginterferon alfa-2 and ribavirin. This study will recruit HCV patients both with and without HIV co-infection.

NCT ID: NCT00214812 Recruiting - HIV Infections Clinical Trials

An Imaging Trial of the Distribution of Topical Gel in the Human Vagina: Assessment of Bare Spots

Start date: June 2005
Phase: Phase 1
Study type: Interventional

This study will assess the distribution of a microbicidal gel in the vagina and confirm the presence of bare spots. MRIs will be done with and without the addition of the MRI contrast Gadolinium to the microbicide in order to determine whether the bare spots are an artifact of the MRI technique.

NCT ID: NCT00214435 Recruiting - HIV Infection Clinical Trials

Once Daily 3TC, Efavirenz and ddI for HIV Infection

Start date: May 2004
Phase: Phase 4
Study type: Interventional

Poor compliance is thought to be a major cause of treatment failure. The TEddI study is a randomised, multi-centre, open-label study in well-controlled treatment-experienced HIV-infected patients to assess compliance with a once-daily regimen of antiretroviral therapy versus continuation of current anti-retroviral regimen delivered at least twice daily.

NCT ID: NCT00206531 Recruiting - HIV Infections Clinical Trials

The Role of Naive T-Cells in HIV Pathogenesis

Start date: n/a
Phase: N/A
Study type: Observational

While HIV mainly infects mature T-cells it can also infect newly produced (or naïve) T-cells. These infected naïve T cells may then act a viral reservoir even in patients with undetectable viral loads. Understanding when and how these cells are infected is important because it could help us to understand why patients fail therapy even if they have a persistently undetectable viral load.

NCT ID: NCT00187512 Recruiting - HIV Infections Clinical Trials

SCOPE: Observational Study of the Consequences of the Protease Inhibitor Era

SCOPE
Start date: March 2000
Phase:
Study type: Observational

SCOPE is an observational, prospective study of HIV-1 infected volunteers designed to provide a specimen bank of samples with carefully characterized clinical data. SCOPE specimens will be used to examine multiple questions involving virologic, immunologic, and host factors involved in HIV-1 infection, progression, non-progression, response to treatment, control of HIV-1 virus, and evolution of drug resistance.
