Although zidovudine (AZT) prolongs life in certain AIDS patients, it is not a cure for AIDS and it also has toxic effects in many patients. Therefore, it is necessary to test other drugs in HIV-infected patients. AL-721 is a mixture of lipids (fats) extracted from egg yolks. Laboratory tests suggest that it might inhibit the infectivity of the HIV. AL-721 has been tried so far in a few patients for short periods of time and has been found to be well tolerated.

Patients receive AL-721 twice daily. The first dose is taken on an empty stomach 1 hour before a fat-free breakfast, with specific instructions given on foods that are allowed; the second dose is taken at least 3 hours after the evening meal. No snacks are permitted after the evening meal or after the evening dose of study medication. The study is scheduled to last for 16 weeks of treatment and 4 weeks of follow-up. Throughout the study, frequent blood samples will be taken from an arm vein. The blood samples are studied to evaluate any changes in the patient's immune system, any toxic effects that might be detected in the blood, and any changes in the presence of the HIV in the blood.

Inclusion Criteria

• Persistent generalized lymphadenopathy (PGL) (CDC-Group III), defined as palpable lymphadenopathy (nodes of 1 cm or greater) at two or more noncontiguous extrainguinal sites persisting for > 3 months in the absence of an illness other than HIV infection to account for the findings.
• AIDS related complex (ARC), defined as the presence of at least one of the following findings within 12 months prior to entry and the absence of a concurrent illness or condition other than HIV infection to explain the findings:
• Any findings which define CDC-Group IV A.
• History of any one of the findings that define CDC-Group IV C2.
• Patients with any of the ARC symptoms can also have PGL and be enrolled in the protocol as ARC patients.
• A positive antibody to HIV by any federally licensed ELISA test kit within 30 days of entry.
