Patients with ARC who are positive for HIV antibody are randomized to receive one of three treatment arms: (1) TNF alone by intramuscular injection (IM); (2) IFN-G alone by IM; (3) TNF plus IFN-G. Patients receive IM injections 3 times weekly for 4 months (16 weeks). Repeated physical examinations and laboratory tests are used to monitor patients' safety. Serial HIV cultures and core antigen assays are employed to obtain evidence of antiviral activity and serial T cell and skin tests are used to measure immunologic effect.
