Active clinical trials for "HIV Infections"

To evaluate the safety and effectiveness of Retrovir (AZT) when used as prophylaxis for health care workers at risk for HIV infection from exposure to HIV-contaminated blood or blood components.

To evaluate the safety and tolerance, in patients with severe clinical manifestations of HIV infection, of zidovudine (AZT) administered daily for 48 weeks as a low dose every 4 hours or a higher dose every 12 hours.

To compare two lipid emulsions in the long-term parenteral alimentation of patients with AIDS in relation to: Clinical effectiveness. Effect on immunologic function. Effect on HIV load as measured by p24 antigen levels. Effect on relative HIV infectivity.

The purpose of this pilot study is to evaluate the efficacy of Retrovir (AZT) in the treatment of AIDS-related dementia and various neuromuscular complications. HIV is both a lymphotropic and neurotropic virus which can affect both the central and peripheral nervous systems (CNS, PNS). There is evidence that the CNS and PNS may harbor the virus in a latent state, with the potential for continuous reinfection of other body systems. Therefore, effective therapeutic efforts against HIV infection should provide effective antiviral activity within the nervous system.

To evaluate the pharmacokinetics of Retrovir (AZT) administered orally as 1 of 3 doses in the treatment of patients with severe clinical and laboratory manifestations of HIV infection. To compare the safety and tolerance of AZT administered 2, 3, and 6 x daily to these patients.

To compare the safety and effectiveness of fluconazole and amphotericin B as maintenance treatment for preventing the relapse of cryptococcal meningitis in patients with AIDS.

To assess the efficacy of Saccharomyces boulardii (a nonpathogenic yeast) in producing a significant reduction in diarrheal symptoms in HIV-infected patients with chronic diarrhea.

To evaluate the efficacy of oral ganciclovir in preventing progression to cytomegalovirus (CMV) disease (e.g., CMV retinitis, gastrointestinal CMV disease) in CMV-infected people with HIV infection and CD4 lymphocyte counts <= 100 cells/mm3. To evaluate the efficacy of this drug in reducing morbidity associated with coinfection by both CMV and HIV.

To evaluate the clinical toxicity, safety, and maximum tolerated dose (MTD) of intravenous nystatin in patients with HIV infection. To evaluate the potential anti-HIV activity and clinical pharmacology of intravenous nystatin.

To determine the tolerance and side effects of a combination of lentinan and didanosine (ddI) compared with ddI alone. To determine whether the combination of lentinan and ddI produces a significant immunorestorative effect within the study observation period (6-12 months) as measured by an increase in one or more of the following: neutrophil count and activity, T-cell subsets, and a decrease in p24 antigen.
