Interleukin-2 (IL-2) can increase numbers of absolute CD4 cells in persons infected with the human immunodeficiency virus who are receiving antiretroviral therapy. Twenty-five subjects with >400/mm3 absolute CD4 cells received zidovudine and low-dose intravenous or subcutaneous IL-2 (106 U/m2). Absolute CD4 cells increased significantly during IL-2 treatment, and 56% of the subjects achieved a maximal increase of ≥500 cells/mm3. A dose-response relationship favored increasing IL-2 doses, and subcutaneous delivery offered greater increases than intravenous administration. Fifteen subjects had persistent increases of ≥100 cells/mm3 6 weeks after IL-2 was discontinued. No changes occurred in delayed-type hypersensitivity or helper T cell responses to recall antigens. Cell-mediated cytotoxicities increased against Daudi cells. IL-2 was well tolerated and only 1 subject required dose reduction. Relatively low-dose IL-2 delivered by subcutaneous or intravenous routes may provide an important complement to antiretroviral therapy to increase absolute CD4 cells with the potential for less toxicity than with higher IL-2 doses. |
