This study will examine the effectiveness of clofazimine in the prophylaxis of Mycobacterium avium complex infection in HIV infected individuals who are at risk to develop this untreatable opportunistic disease. In the absence of truly effective antiretroviral therapy, a potential mode of treatment of patients with HIV infection is to prevent the development of the life-threatening opportunistic infections. Current studies demonstrate a possible efficacy of clofazimine in the prophylaxis against Pneumocystis carinii pneumonia (PCP), the most common AIDS-defining opportunistic infection. Future studies will examine the potential for prophylaxis against the other opportunistic infections. This proposal hopes to define the role of prophylactic clofazimine in preventing the currently untreatable Mycobacterium avium complex infection. AMENDED: To include prophylaxis for Asymptomatic and ARC.
The objective of this double-blind placebo-controlled study is to evaluate the effect of Isoprinosine in a group of homogenous male volunteers who present with immunologic defects relative to: - Comparison of total helper and suppressor T-cell number between the groups. - Comparison of the phytohemagglutinins (PHA) and concanavalin A lymphoproliferative response and natural killer (NK) cell activity between the groups. - Determination of the clinical course of the volunteers after discontinuance of Isoprinosine.
The objective is to determine the effect of Isoprinosine (inosine pranobex) in homosexual male patients with AIDS related complex (ARC) in delaying the onset of AIDS. Secondly, to determine the effect of Isoprinosine in decreasing the severity and/or incidence of lesser opportunistic infections and/or other conditions associated with ARC.
The objective of this Phase III, randomized, double-blind, placebo-controlled study in patients with immunologic deficiency is to determine the effect of isoprinosine in producing an immuno-restorative response within the study observation period (including the 2-month period following cessation of the 28 days of treatment), measured by one or more of the following immunologic parameters: - Increase in natural killer (NK) cell activity. - Increase in total T-cells (OKT-11). - Increases in absolute number and percentages of T-helper cells (OKT-4).
This protocol provides for the availability of spiramycin under compassionate-use conditions for the treatment of chronic diarrhea due to cryptosporidium in patients with a compromised immune system, thus deriving additional information regarding its safety and efficacy profile.
Primary: To determine the clinical effect of zidovudine (AZT) compared to placebo in terms of time to progression to AIDS (i.e., occurrence of major opportunistic infections, dementia, and malignancies) or death. Initial drug assignment will be changed to open-label AZT for patients who experience a sustained decline in CD4 lymphocyte concentration to less than 200 cells/mm3, but analysis will be based on initial treatment assignment. To determine the immunologic effect of AZT compared to placebo in terms of time to drop in CD4 lymphocyte concentration of at least 25 percent from baseline assessment. To determine the antiviral effect of AZT compared to placebo in eradicating or suppressing HIV. Secondary: To determine the effect of AZT compared to placebo on the immune status of HIV-infected patients by comparing lymphocyte profiles and indices. To determine the long-term toxicities of AZT compared to placebo in terms of abnormalities in BL, hepatic function, renal function, skin, gastrointestinal system, and central nervous system. To describe the natural history of AIDS related complex (ARC) in placebo patients in terms of initial CD4 lymphocyte concentration and the Walter Reed staging system.
To compare pyrimethamine and intravenous (IV) clindamycin vs. pyrimethamine and sulfonamides in the treatment of AIDS patients with central nervous system (CNS) Toxoplasma gondii.
To assess the safety and efficacy of depot disulfiram as a new treatment for AIDS and AIDS related complex.
Examine the ability of thymopentin (Timunox) to: Reduce the amount and/or frequency of virus isolation. Stimulate the immune system and alter the clinical findings in patients infected with HIV who do not yet have AIDS.
To compare the effects of megestrol acetate and placebo on body weight, anorexia, cachexia, calorie intake, and nutritional parameters of patients with a confirmed diagnosis of AIDS. To determine whether megestrol acetate relative to placebo improves the perception of well-being among AIDS patients with cachexia. To evaluate megestrol acetate's effect on immune function via skin test reactivity, T4/T8 ratio, and total lymphocytes.
