Active clinical trials for "Infections"

To evaluate the safety and tolerance of long-term ganciclovir (DHPG) therapy for newly diagnosed macular threatening Cytomegalovirus (CMV) retinitis in AIDS patients. To evaluate the clinical response to a 52 week course of intravenous DHPG therapy. To evaluate the safety and tolerance of long-term DHPG with concurrent treatment with zidovudine (AZT). (Patients utilizing treatment with other anti-retroviral drugs will be considered for study entry on a case by case basis.) To determine survival in this group of patients with AIDS and CMV retinitis.

To compare the effectiveness of standard treatment with parenteral ampicillin and oral amoxicillin compared to initial daily therapy with ceftriaxone followed by 3 times weekly suppressive treatment for salmonella infections in AIDS patients.

To determine whether co-administration of sargramostim (granulocyte-macrophage colony-stimulating factor; GM-CSF) improves tolerance to ganciclovir in patients previously intolerant because of neutropenia defined as an absolute neutrophil count less than 500 cells/mm3. To assess if improved tolerance of ganciclovir is associated with a favorable outcome as defined by a delayed time to progression of retinitis; to confirm the safety and co-administration of ganciclovir and GM-CSF; to assess the changes in the expression of HIV p24 antigen in the serum and number of T4+ lymphocytes in the blood of patients receiving ganciclovir with or without GM-CSF.

Primary: To determine whether the combination of zidovudine/zalcitabine/interferon alfa-n1 (Retrovir/HIVID/Wellferon) can produce complete responses (i.e., CD4 counts return to >= 800 cells/mm3 for more than 24 weeks) in patients with virus sensitive to all three agents. To determine the antiviral effect of the combination therapies as evidenced by measures of quantitative viral load performed at select study centers only. Secondary: To determine the effectiveness of Retrovir/HIVID and Retrovir/HIVID/Wellferon in maintaining or increasing CD4 counts and preventing disease progression as evidenced by the development of an AIDS-defining indicator disease. To determine the effect of these regimens on secondary measures of clinical status (e.g., performance score, weight change, and secondary infections) and on measures of virologic activity such as serum p24 antigen. To assess the safety and tolerance of these regimens.

To evaluate the efficacy and safety of two doses of azithromycin given chronically for the treatment of Mycobacterium avium bacteremia in AIDS patients.

The purpose of this study is to see if it is safe to give a combination of four anti-HIV drugs to patients recently infected with HIV who have never received anti-HIV treatment. The effects of this combination of drugs on the immune system and the level of HIV in the body are studied also. The four-drug combination includes lamivudine, abacavir, amprenavir, and indinavir.

To determine the safety, tolerance, and potential in vivo antiviral effects of five dosage levels and a dose to be determined of human anti-cytomegalovirus (CMV) monoclonal antibody (SDZ MSL-109; formerly SDZ 89-109) when administered once every 2 weeks for a total of 12 doses to patients with either AIDS or eligible AIDS-related complex (ARC) and with culture proven evidence of CMV viremia and/or viruria. Sandoglobulin will be employed as a comparative control.

To attempt to demonstrate the efficacy of ganciclovir (DHPG) treatment of cytomegalovirus (CMV) colitis in AIDS patients by evaluating both clinical and virologic parameters. To determine acceptability and the safety profile of a 2-week course of intravenous (IV) DHPG therapy.

This double-blind, placebo-controlled study is designed to determine the long-term safety and efficacy of concurrent oral Retrovir / Zovirax (AZT and ACV) therapy and oral AZT therapy alone, in the treatment of early symptomatic HIV infection. Efficacy will be evaluated by monitoring the incidence, severity, and time of development of opportunistic infections and other manifestations of advanced symptomatic HIV infection. The effects of the combination and single AZT therapy on immune function and viral replication will also be evaluated. Study participants will be monitored for evidence of toxicity or intolerance to concurrent AZT / ACV administration and AZT therapy alone.

The purpose of this study is to see if it is safe and effective to give adefovir dipivoxil plus abacavir (ABC) plus efavirenz (EFV) plus amprenavir (APV) to HIV-infected patients who have failed to respond to previous treatment with protease inhibitors (PIs).
