Filter by:To evaluate the efficacy and safety of two different doses of azithromycin in combination with ethambutol for the treatment of patients with Mycobacterium avium complex (MAC) infection, and to determine whether an azithromycin-containing regimen is at least as safe and effective as the same regimen containing clarithromycin..
PRIMARY: To determine the efficacy of azithromycin and rifabutin alone and in combination for the prevention of disseminated Mycobacterium avium Complex (MAC) infection in HIV-infected patients. To determine the efficacy of daily versus weekly fluconazole for the prevention of deep fungal infections in this patient population. SECONDARY: To determine the incidence of bacterial (including mycobacterial) infections, cryptosporidiosis, and toxoplasmosis in azithromycin versus non-azithromycin containing regimens. To determine the incidence of oropharyngeal and vaginal candidiasis in patients treated with daily versus weekly fluconazole. To compare survival and outcomes of primary endpoints in the treatment arms.
To demonstrate, in patients with tubercular or nontubercular mycobacterium infections with or without HIV infection, the safety of thalidomide use as judged by symptoms, physical exam, and studies of microbiologic, immunologic, hematologic, renal, and hepatic status. To demonstrate efficacy of the drug as judged by status of fever, nutrition, tuberculosis lesions, and immune responses.
To compare the efficacy of clarithromycin/ethambutol with placebo or with rifabutin at two different doses in reducing colony-forming units (CFUs) by 2 or more logarithms in patients with Mycobacterium avium Complex bacteremia and maintaining this response until 16 weeks post-randomization. To assess survival and comparative tolerability among the three treatment regimens.
To evaluate the efficacy and safety of two doses of azithromycin given chronically for the treatment of Mycobacterium avium bacteremia in AIDS patients.
To evaluate the efficacy and safety of azithromycin given chronically for the treatment of Mycobacterium avium (MAC) bacteremia in patients failing or intolerant of current available MAC therapy.
To evaluate the efficacy and safety of azithromycin given chronically for the treatment of serious nontuberculous mycobacterial infection in patients failing or intolerant of other available 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.
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.
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.
