Active clinical trials for "Communicable Diseases"

To evaluate the efficacy of dinitrochlorobenzene (DNCB) in patients with early HIV infection by monitoring immunologic parameters and serum HIV RNA. To facilitate the understanding of possible alterations in the immunological status of the HIV+ patient cohort.

To assess the magnitude and duration of the antiviral activity in plasma and the incidence and time to total suppression of detectable HIV RNA in plasma. To assess the long-term safety and tolerability of this combination therapy and the magnitude and duration of the effect of this therapy over CD4 cell counts.

To compare the safety, tolerance, and efficacy of saquinavir mesylate (Ro 31-8959) alone, zalcitabine (dideoxycytidine; ddC) alone, and both in combination, in patients discontinuing or unable to take zidovudine (AZT).

To determine whether clarithromycin is safe and effective in preventing disseminated Mycobacterium avium Complex in HIV-infected patients with CD4 counts <= 100 cells/mm3.

To determine the safety and pharmacokinetics of L-ofloxacin (RWJ 25213) in patients with HIV infection.

To study the effectiveness of alpha interferon (IFN-A2b) and zidovudine (AZT) in treating progressive multifocal leukoencephalopathy (PML) as a complication of HIV-1 infection.

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 examine the effectiveness of subcutaneous gamma interferon in reducing severity of Mycobacterium avium- intracellulare (MAI) bacillemia episodes in AIDS patients in an open-label dose-randomized multi-center pilot clinical investigation. To evaluate the safety of gamma interferon given by subcutaneous injection (SC) in the AIDS patient in the presence and absence of AZT therapy.

Primary: To provide rifabutin to HIV positive patients in an attempt to prevent or delay Mycobacterium avium Complex (MAC) infection by a daily dose of rifabutin. Secondary: To further characterize the safety of rifabutin monotherapy in preventing or delaying MAC bacteremia in HIV positive patients with CD4 counts = or < 200.

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.
