A Study of Three Drugs Plus Zidovudine in the Prevention of Infections in HIV-Infected Patients

A Randomized Trial of Three Anti-Pneumocystis Agents Plus Zidovudine for the Primary Prevention of Serious Infections in Patients With Advanced HIV Infection

To evaluate and compare 3 anti-pneumocystis regimens plus zidovudine (AZT) in persons with HIV infection and T4 cell count less than 200 cells/mm3. All persons completing at least 8 weeks of therapy on 081 will be offered the opportunity to participate in the nested study (ACTG 981) of systemic antifungal therapy (fluconazole) versus local therapy (Clotrimazole) for the prevention of serious fungal disease.

Persons with HIV disease who are receiving AZT are at risk for PCP, toxoplasmosis, bacterial pneumonia, and other serious infections. It is therefore important to find drugs that can be given along with AZT to control these infections. Aerosolized pentamidine (PEN) has been shown to be useful in preventing PCP and is expected to lower the 2-year risk of PCP. Both sulfamethoxazole/trimethoprim (SMX/TMP) and dapsone probably also provide effective preventive treatment against PCP, and both may be useful in preventing toxoplasmosis and extrapulmonary pneumocystosis.

Study Overview

Detailed Description

Persons with HIV disease who are receiving AZT are at risk for PCP, toxoplasmosis, bacterial pneumonia, and other serious infections. It is therefore important to find drugs that can be given along with AZT to control these infections. Aerosolized pentamidine (PEN) has been shown to be useful in preventing PCP and is expected to lower the 2-year risk of PCP. Both sulfamethoxazole/trimethoprim (SMX/TMP) and dapsone probably also provide effective preventive treatment against PCP, and both may be useful in preventing toxoplasmosis and extrapulmonary pneumocystosis.

All patients receive AZT. In addition, they are placed in one of three groups to receive either SMX/TMP, dapsone, or PEN. Stratification criteria are:

Received first AZT equal to or less than 6 weeks prior to study entry. Received first AZT more than 6 weeks prior to study entry. Potential to participate in ACTG 981. ACTG center in which the patient is enrolled.
