Oncogenic Viral Pathogenesis and Cancer Risk Factors Among Patients With the Acquired Immunodeficiency Syndrome: A Prospective Cohort Study
The purpose of this study is to find out why cancers develop in HIV-positive patients. Cancer is a leading cause of death in AIDS patients. Common cancers in HIV-infected patients include Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL), a cancer of the immune system. Risk factors include certain chemicals, viruses, and perhaps even anti-HIV drugs. Doctors would like to find out which risk factors are most important and how they relate to cancer in AIDS patients.

A Phase II/III Placebo-Controlled Study of Nitazoxanide (NTZ) For Persons With AIDS and Cryptosporidiosis
To determine the frequency of complete, marked, and partial clinical responses in patients with cryptosporidiosis treated with 6 weeks of NTZ versus 21 days of placebo. To determine the safety of NTZ in subjects with cryptosporidiosis. There is no proven therapy for cryptosporidiosis in persons with AIDS. Nitazoxanide appears to be a good candidate drug for further evaluation because of its effectiveness in preclinical models, the data from early clinical trials and its safety profile. Cooperation between clinical researchers and basic scientists in clinical trials of agents for HIV infection and its complications is a high priority for the ACTG, the NIAID, and the NIH. Thus, it is important to design a clinical trial of NTZ that includes cooperation with basic scientists.

An Observational Study of the Rate of Opportunistic Infection Events in HIV-Infected Children Who Have Demonstrated Immunologic Reconstitution and Who Have Discontinued OI Prophylaxis
The purpose of this study is to find out if it is safe for HIV-positive children who are responding well to their anti-HIV treatment to stop taking medications that prevent AIDS-related infections (opportunistic infections) such as pneumonia and other bacterial infections. This is an observational study, meaning children will only be monitored to see if they develop any infections. Children have been receiving medications to prevent complications of HIV infection, such as Pneumocystis carinii pneumonia (PCP), Mycobacterium avium complex (MAC) disease, or other bacterial infections. It is common for HIV-positive patients with low CD4 counts to receive these preventive medications. However, these drugs can have serious side effects, they are expensive, and it is possible for bacteria resistant to the drugs to grow. For these reasons, it may be beneficial to the child to stop taking these preventive medications if he/she has been on anti-HIV (antiretroviral) therapy and has improved CD4 counts. This study will look at how many children who stop taking their medications develop opportunistic infections.

A Phase II, Double-Masked, Randomized, Placebo-Controlled Evaluation of Standard Therapy vs. Standard Therapy Combined With Human Monoclonal Anti-Cytomegalovirus Antibody (MSL 109) in the Therapy of AIDS Patients With Cytomegalovirus (CMV) Retinitis
To evaluate the effect of MSL 109, human monoclonal anti-cytomegalovirus (CMV) antibody, on time to progression of CMV retinitis. To determine the safety and pharmacokinetic profile of MS 109. To evaluate the relationship between pharmacokinetic measurements of MSL 109 and efficacy and virologic markers. Therapeutic agents currently available for CMV retinitis are limited by their inherent toxicities and short half-lives which require frequent intravenous dosing. Alternatively, MSL 109 has demonstrated safety and effectiveness in neutralizing CMV isolates at concentrations easily maintained in AIDS patients.

Comparison Study of Liposomal Doxorubicin With or Without Bleomycin and Vincristine for the Treatment of Advanced AIDS-Associated Kaposi's Sarcoma
To evaluate the safety and efficacy of liposomal doxorubicin hydrochloride ( DOX-SL ) alone or in combination with bleomycin and vincristine in the long-term treatment of AIDS-related Kaposi's sarcoma. To determine whether the 3-drug combination enhances progression-free survival and quality of life. Liposomal formulations of chemotherapeutic agents increase drug accumulation in tumors, which permits disease palliation at relatively low doses and thus decreases some of the dose-limiting toxicity. Multi-agent therapy is considered to be more effective than single-agent therapy; therefore, DOX-SL will be combined with bleomycin and vincristine.

Women's AIDS Cohort Study (WACS)
To study the effect of pregnancy, age, drug use, and coinfections on HIV progression rate. To document the prevalence, incidence, characteristics, and course of HIV infection and anogenital intraepithelial neoplasia among HIV-positive and HIV-negative women. To study the effect of HIV disease on gynecologic health including infections and reproductive function.

A Multicenter, Open-Label Study of Viral Burden in Peripheral Blood Versus Lymphoid Tissue Before and After Antiretroviral Therapy in HIV-Infected Individuals Without AIDS (NOTE: One Arm Receives no Treatment)
Immunopathogenesis objectives: To compare and quantitatively determine HIV burden and HIV replication in peripheral blood (PB) and lymphoid tissue (LT). To determine the degree to which antiretroviral therapy alters HIV replication in LT. Clinical objectives: To gain insight into the degree of correlation between immunologic surrogate markers for HIV disease (e.g., CD4, beta-2 microglobulin) as compared to measures of HIV replication in PB and LT. To assess changes in PB and LT viral burden after antiretroviral therapy and to determine its ability to predict an antiviral response. One of the major problems in defining the immunopathogenic changes in HIV infections has been the inability to correlate the extent of loss of immunologic function with the number of HIV-infected CD4+ cells in the peripheral blood. Few studies exist that measure viral burden in lymph nodes of HIV-infected individuals. Researchers hope to find out whether the amount of HIV virus or markers for the virus in the body's lymph tissue is a better measure of disease progression than the amount of virus or markers for the virus in the blood.

Comparison of Fluconazole (UK-49,858) and Amphotericin B for Maintenance Treatment of Cryptococcal Meningitis in Patients With Acquired Immunodeficiency Syndrome
To compare the safety and effectiveness of a new drug, fluconazole, with that of the usual therapy, amphotericin B, in the prevention of a relapse of cryptococcal meningitis (CM) in patients with AIDS who have been successfully treated for acute CM in the last 6 months. Cryptococcal meningitis is a life-threatening infectious complication of AIDS. Because relapse after treatment occurs in over 50 percent of cases, chronic maintenance therapy with intravenous (IV) amphotericin B is usually given. However, amphotericin B is not always effective, has toxic effects, and must be given by the intravenous route. Fluconazole is an antifungal agent that can be given orally and has been shown to be effective against cryptococcal infections in animals and against acute CM in a few AIDS patients. Also, the side effects experienced by over 2000 patients or volunteers given fluconazole have seldom been severe enough to require withdrawal of the drug.

The Safety and Efficacy of Zidovudine in the Treatment of Patients With Early AIDS Related Complex
To determine the safety and usefulness of zidovudine (AZT) for the treatment of patients with early symptomatic HIV infection or early AIDS related complex (ARC). The ability of AZT to suppress HIV, to improve body defenses, and to prevent the occurrence or development of AIDS or advanced ARC is being evaluated. In one human study, patients with AIDS or advanced ARC who received AZT had fewer life-threatening infections, improved in weight and performance, and lived longer than patients who received a placebo (inactive medication). Further studies are needed because toxic effects associated with the use of AZT were noted and the long-term effectiveness and toxicity of AZT are still unknown. It is also unknown if AZT will benefit patients with less severe HIV infections such as early ARC or PGL.

A Phase I/II Dose Ranging Trial of Oral Dextran Sulfate (UA001) in HIV Infected Individuals and in Patients With Acquired Immunodeficiency Syndrome (AIDS) or AIDS Related Complex (ARC)
To determine the effectiveness and safety of dextran sulfate (DS) as a treatment for patients with AIDS, AIDS related complex (ARC), or asymptomatic HIV infection with or without persistent generalized lymphadenopathy (PGL), and to determine antiviral activity at different doses of DS. Although zidovudine (AZT) has shown promise in prolonging life in patients with AIDS and severe ARC, it has significant blood toxicities. It would be beneficial to combine AZT with another antiviral agent that does not have the same toxicity. DS might be a suitable drug since it has shown antiviral activity against HIV in the laboratory, and in preliminary studies it has shown little toxicity. Also, the combination of DS with AZT has been shown to be more effective than either alone.
