Active clinical trials for "HIV Infections"

Patients with congenital or acquired immunodeficiencies are at an increased risk to develop polyclonal or oligoclonal lymphoid malignancies. Some develop a lymphoproliferative disorder that can follow a clinically aggressive course and may represent a pre-malignant lesion. Although most of these lymphoproliferative disorders are of B-cell origin, T-cell or non-B-non-T-cell processes have also been observed. The pathogenesis is only partially understood. In the case of pre-malignant conditions it is often difficult to know when and whether a therapeutic intervention is necessary and a careful consideration of potential treatment-associated morbidity is indicated. Therapies have ranged from influencing the possible infectious etiology (by treating with acyclovir), decreasing the amount of immunosuppression (in transplant patients), to the use of immunomodulatory agents, including interferons and interleukins. Recent data have indicated that the use of differentiating agents, such as the retinoids, might offer yet another treatment option. In the current study we will try to get a better understanding of the pathogenesis and natural course of lymphoproliferative disorders in immunodeficient children. The study will have two parts: an initial observation period to obtain information on the natural course of these disorders, and then a six month treatment period with the combination of a differentiating agent (13-cis-retinoic acid was used until all-trans-retinoic acid became available on 7/96) with an immunomodulatory agent (interferon-alpha2a, IFN-alpha2a).

Several dideoxynucleosides have now been shown to have activity against HIV but to have different toxicities. This study will involve therapy of patients with AIDS or ARC with two of these agents, AZT and 2', 3'-dideoxyinosine (ddI), which have different toxicity profiles, over a 2-year period of time. The rationale for using the two drugs will be to reduce toxicity and also possibly to delay or prevent the development of resistance. Patients will be randomized to receive either an alternating regimen or a continuous simultaneous regimen with these two drugs. The study will be structured as a randomized pilot study.

To conduct a double-blind, randomized, dose ranging study of an orally administered low dose interferon alfa-n3 (IFN-An3) immunomodulator in the treatment of symptomatic HIV+ subjects.

The purpose of this study is to see whether it is better to take delavirdine (DLV) plus indinavir (IDV) plus zidovudine (ZDV) twice a day or three times a day.

The purpose of this study is to find out whether hormonal birth control increases, decreases, or does not change the risk of women becoming infected with HIV. Sexual intercourse between men and women is the main way HIV is transmitted. About 90 percent of HIV infections in women are caused by sexual intercourse. Also, hormonal birth controls are widely used. This study hopes to find out whether hormonal birth control changes the risk of women becoming infected with HIV.

To compare the relative merits of three therapeutic regimens in patients with AIDS and CMV retinitis who have been previously treated but whose retinitis either is nonresponsive or has relapsed. These three therapeutic regimens were (1) foscarnet, (2) high-dose ganciclovir, and (3) combination foscarnet and ganciclovir. To compare two treatment strategies in patients with relapsed or nonresponsive CMV retinitis: (1) continuing the same anti-CMV drug or (2) switching to the alternate drug.

In natural HIV disease, a small fraction (1-2%) of infected individuals develops exceptionally high titres of HIV-1 neutralizing serum activity. Antibodies isolated from these individuals have been shown to be highly active against a broad range of different HIV strains and are therefore called broadly neutralizing antibodies (bNAbs). These antibodies are in fact able to prevent (S)HIV infection in animal models and therefore of great interest for the development of an HIV vaccine. Information of neutralizing antibodies in patients from Africa is still scarce and would be of great value in the development of adapted HIV vaccine strategies in these regions. This study aims to investigate African HIV-infected individuals, who have developed neutralizing antibodies using highly specialized laboratory methodologies.

The purpose of this study is to create a smartphone, tablet and web-based application to help people deal with stress. Stress often increases fatigue in people with HIV infection, so successfully dealing with stress could help reduce HIV-related fatigue. The study is being done at one site, the Medical University of South Carolina. Approximately 30 people will take part in this portion of the study.

A clinical study for patients with HIV that investigates the best way to reduce HIV transmission risk, and to improve the overall health of people living with HIV/AIDS. Participants will complete four assessments over the course of one year and will be randomly assigned to a five-week treatment program.

This study is a prospective observational cohort. The target study population is PLHIV who receive ART at hospitals and community-based organizations (CBOs) in Chiang Mai, Ubon Ratchathani, Chonburi, and Songkhla. Participants will receive ART service in the same standard as in the hospital setting. Secondary data will be collected from the medical records already existed in the hospital and CBO systems.
