Summary

1\) To determine whether it is possible to remove and culture (increase in number and activate) in the laboratory, CD8(+) lymphocytes (white blood cells) from HIV-infected patients receiving zidovudine (AZT); 2) To determine the toxicity of returning to the patients intravenously the expanded and activated autologous cells (given to the patient from whom they were taken), with and without giving the patients recombinant interleukin-2 ( aldesleukin; IL-2 ) at the same time; 3) To radiolabel (mark) the CD8(+) lymphocytes with Indium 111, and then scan the patients to determine the distribution of the CD8(+) lymphocytes in those who are and are not given IL-2 infusions; 4) To determine the toxicity of IL-2 given at the same time with autologous CD8(+) lymphocytes; 5) To measure changes in the immunology of the subjects following these treatments.

CD8(+) cells are suppressor/killer lymphocyte cells that act to limit replication of viruses. It is hoped that the reinfusion of activated autologous CD8(+) cells into patients with AIDS will help to control opportunistic infections such as cytomegalovirus and toxoplasmosis (two of the leading causes of sickness and death in AIDS patients). This treatment may also stop the HIV virus from replicating (reproducing itself) in the AIDS patient. Further activation of these cells, once infused, may be necessary. It is hoped that IL-2 will stimulate the patient's immune system against the AIDS virus along with the activated CD8(+) cells. Thus, IL-2 will be given, and its effects studied.
