Subcutaneously Administered Aldesleukin ( Interleukin-2; IL-2 ) Therapy in HIV-Infected Patients

To compare the effects of low-dose versus high-dose subcutaneous ( SC ) aldesleukin ( interleukin-2; IL-2 ) on immunologic and virologic markers in HIV-infected patients. To compare the effects of monthly versus bimonthly administration of SC IL-2 on these markers. Interleukin-2 is a protein that is naturally produced by lymphocytes. In an initial study, patients in an earlier stage of HIV-1 infection tended to tolerate SC IL-2 better than those with more advanced infections, and those with higher baseline CD4+ counts tended to derive the greatest benefit.
